Many products are made from sheet metal - drainage systems, shaped parts for cladding or metal tiles, flashings for bases, corners for structures made of corrugated sheets, etc. All this can be done by a special bending machine for sheet metal. We’ll talk about how to make a sheet bending machine with your own hands in this article.
Types of sheet benders
All these devices are classified as sheet bending machines. The easiest way to make one with your own hands is the unit of the first group, a little more difficult - the third (rollers for sheet metal). So we’ll talk about them - from how to make a sheet bending machine with your own hands.
Simple manual
Shaped metal parts cost a lot of money. Even more than corrugated sheeting or metal tiles, therefore it makes sense to make a simple machine for bending sheet metal, and with its help make as many corners, ebbs and other similar parts as you need, and exclusively to your own dimensions.
Bending machine - side view 
If you're worried about appearance, you shouldn't be. On sale today there is sheet metal not only galvanized, but also painted. In all designs, the sheet is fixed tightly, so that when working it does not slide on the table, which means that the paint does not rub off or get scratched. It is also not damaged in places of bending. So the products will look quite decent. If you try, they will look even better than what they sell on the market.
Powerful sheet bending machine from brands
This sheet bending machine will require a flat surface (table), preferably metal, three corners with a shelf width of at least 45 mm, and a metal thickness of at least 3 mm. If you plan to bend long workpieces (more than a meter), it is advisable to take wider shelves and thicker metal. You can use brands, but this is for bending metal sheets of large thickness and length.
You will also need metal door hinges (two pieces), two large diameter screws (10-20 mm), wings on them, and a spring. You will also need a welding machine - weld the hinges and make holes (or a drill with a metal drill bit).
For a homemade sheet bender, a 70 mm brand was used - three pieces of 2.5 m each, two bolts of 20 mm in diameter, a small piece of metal 5 mm thick (for cutting jibs), a spring. Here's the procedure:
- Two brands are folded, and grooves are cut into them at both ends for hinges. The edges of the recesses are beveled at 45°. The third tee is cut in the same way, only the depth of the recess is made a little larger - this will be the clamping bar, so it should move freely.
- Weld the loops on both sides (weld on the front and back).
- Two jibs on each side are welded to one of the brands (the one farthest from you, if you “open” them). They are needed so that you can install the clamping bar clamp bolt on them.
- Weld the bolt nut to the jibs.
- Install the clamping bar (third cut tee), weld metal plates with a hole in the middle in the upper part. The diameter of the hole is slightly larger than the diameter of the bolt. Center the holes so that they are on the same vertical line with the welded nut. Weld.
- Cut the spring so that it raises the pressure bar by 5-7 mm. Pass the bolt into the “ear” of the clamping bar, put on the spring, tighten the nut. After installing the same spring on the other side, the clamping bar rises on its own when unscrewed.
- Weld two pieces of reinforcement to the screw head to serve as handles for tightening.
- Weld a handle to the movable (closest to you) brand. That's it, you can work.
This option is very powerful - you can bend long workpieces and sheets of considerable thickness. Such scales are not always in demand, but they can always be reduced. The video suggests a similar design of a smaller size, but with a different fastening of the clamping bar. By the way, no one bothers you to also install a spring on the screw - it will be easier to raise the bar. What’s interesting about this design is that you can make beading on it, something that such devices usually cannot do.
From a corner with a different type of clamping bar
This model is welded from a thick-walled angle, the frame is made like an ordinary construction sawhorse, which is welded from the same angle. The handle is from a luggage trolley. The design of the screws is interesting - they are long, the handle is curved in the shape of the letter “L”. Convenient to unscrew/screw.
This homemade sheet metal bending machine has many features:
Now let's move on to the design of the clamping bar (pictured above). It is also made from a corner, but is laid on the machine with an upward bend. To ensure that the bar does not bend during operation, reinforcement is welded on - metal jumpers. Small metal platforms are welded at both ends of the strip, in which holes are drilled for bolts.
Another important point is that the edge that faces the bend is cut off to obtain a sharper bend angle.
The clamping bar is placed on the machine, and a spring is placed in the place where the nut is installed. The handle is installed in place. If it does not press the bar, it is raised above the surface due to the elastic force of the spring. In this position, the workpiece is tucked under it, positioned, and pressed.
Place a spring under the hole, then a bolt
A good option for home use. It will not be possible to bend thick metal, but tin and galvanized steel can be bent without difficulty.
Sheet metal rollers or roller bender
This type of sheet bending machine can have three types of drive:
- manual;
- hydraulic;
- electric.
They make rollers for sheet metal with manual or electric drive with their own hands. Manual ones have 3 shafts, electric ones can have 3-4, but usually there are also three.
This machine needs a good solid foundation. This could be a separate bed or some kind of workbench or table. The basis of the structure is rolls. They are made the same size. The two lower ones are installed permanently, the upper one is movable, so that in the lower position it is located between the rollers. By changing the distance between the lower rollers and the upper one, the radius of curvature changes.
The machine is set in motion using a handle attached to one of the shafts. Then the torque is transmitted to other rollers through sprockets. They are selected so that the rotation speed is the same.
If the equipment is intended to produce pipes, the upper roller on one side is made removable, with a quick fixation system. Once the sheet is rolled into a pipe, there is no other way to pull it out.
A bending machine for sheet metal can be made at home. Not every home craftsman needs such equipment, but for those, for example, who do roofing work, it will help to significantly increase their own earnings. And for some, perhaps, it will become the first machine of the future plant.
Reasons why you should assemble a sheet bending machine yourself
Why should you even bother making such complex equipment yourself? To answer this question, let's go in reverse and look at alternative methods for obtaining valleys, ridges, gutters, eaves strips and other structural fragments.
Although, I would like to immediately note that this is far from the only industry that requires products created by bending iron. Just now, for clarity, we’ll touch on it.
Do without a machine at all
There are two options here:
- Purchasing ready-made samples, which significantly exceed the price of sheet metal and even the labor costs required to process it. That is, it is simply a refusal of a significant part of earnings in favor of industrial plants;
- The old fashioned way is to use a punch to get the desired shapes. But this will lead to the immediate loss of many customers who prefer products without a brandy look. The modern market is very cruel in this regard: everyone wants both quality and beauty.
Buy a ready-made machine
Let's look at a hypothetical situation in numbers. On average, a manual sheet bender can cost you $1,500-$2,000. In theory, it will be possible to turn in a couple of days a ton of galvanized iron 0.55 mm and worth 1000 US dollars into 250 square meters of corrugated sheets, which are already valued at 1400 of the same monetary units.
It seems that everything is turning out beautifully, but in your mind you are already calculating not only the return on purchase, but the colossal profits received in the future.
But, unfortunately, everything is not so rosy in practice, where the following difficulties will stand in your way:
- When rolling corrugated sheets, corners often become too tight, resulting in the need to repeat the operation. This already leads to an increase in theoretical work time;
- Violations of intercrystalline metal bonds are possible. After a while, cracks begin to creep in such places. You will have to redo such a marriage at your own expense.
A line that is free of such problems already costs around 20,000 US dollars, which will be even more difficult to recoup. Plus, this all applies to the case when you have sales of manufactured products. And if you only occasionally need certain products to fulfill an order for roofing work, then the profitability of even the cheapest purchased equipment is out of the question.
For clarity and the opportunity to think about this issue yourself, I will give you examples of some specific models of machine tools that can be purchased ready-made:
- Model "Tapco Max 20-08":
- Model “Van Mark Metal Master Commercial MM 1051”:
Step-by-step assembly process
The instructions for making a sheet bending machine begin with solving some theoretical questions:
Step No. 1: decide on the type of drive
In order to bend sheet metal, one of the following drives can be designed and used:
- Mechanical. It can be presented in the form of a flywheel with a friction clutch and a crank, or in the form of a falling weight with a system of cables, blocks and levers. It has a high efficiency, but is not at all suitable for our case. The fact is that at the beginning of its working stroke there is a sharp blow, which then weakens, and for bending metal sheets exactly the opposite effect is required;
- Electric. Here we observe a problem of a different nature: a significant drop in efficiency and an increase in energy consumption when working with small-sized fragments. This is due to the fact that with the resistance of the bent steel, the engine slip increases and the torque decreases;
- Hydraulic. In these devices, the hydraulic cylinder independently adjusts its force to the resistance of the metal part. They would be ideal if they weren't too expensive for a homemade machine;
- Manual. Despite the fact that in this case the driving force will be your hands, such a drive is ideal for a homemade machine. It is the easiest to manufacture, does not require the consumption of electrical energy and is inexpensive.
At the same time, you get the necessary and uniform force. We will choose the handbrake for the construction of a homemade sheet bender.
The main thing is to design the unit correctly so that during its operation the strongest muscle groups work, and the recoil presses the operator’s feet to the floor. In this case, the process will not be too exhausting.
Step No. 2: select a working scheme for the machine
Now you need to decide how your homemade sheet metal bending machine will work.
You can choose from the following schemes:
- Using a traverse. This method allows you to bend steel sheets by hand with a thickness of up to 0.5 mm. You can see it in the diagram:
When using the described method, I recommend that you lean on the traverse in its lower part and push it forward a little, as if smoothing the steel. In this case, the bend will be as correct and accurate as possible.
- Using a press. This option is actively used in industry. For a private workshop, it is too dangerous, since if there is the slightest malfunction in the device or an error in filling the material, the sheet can slip out and cause serious damage to the operator;
- With shaft system. These are just those broaching sheet benders that can be bought for around 1500-2500 US dollars. Can be manual or electric. Very easy to use, but difficult to implement with your own hands.
The easiest way is to create a sheet bending machine with your own hands, bending metal using a traverse, which means we will consider this option further.
Step No. 3: determine the main parameters of the future machine
A homemade sheet bender must have the following qualities to be effective at home:
- Do not overexert the operator. Since we have settled on a manual drive, then let work at the machine not become hard labor for you;
- Be simple from a technical point of view and inexpensive;
- Easily be transported. Very often you may need to bend parts directly at the roofing site.
Based on the above, I propose to focus on the following technical characteristics of the manufactured device:
Step No. 4: draw up a drawing that meets all the listed conditions
Handbrake, traverse, ease of use, compactness and several other important parameters. Now let’s transfer all this to the drawing:
Material of all components – structural steel. Separately, I would like to dwell on the traverse.
In many descriptions you may find that it is suggested to use a corner. I strongly advise installing a channel that will withstand 6 times more operating cycles. As for the sizes, for our case the optimal size would be 8-10 cm.
Step No. 5: proceed to familiarization with detailing and production of basic elements
There are never too many drawings. The more detailed everything is written down on paper, the less chance there is of making a mistake during the assembly process. Therefore, I bring to your attention the details of the equipment being manufactured:
We assemble the pressure beam in accordance with the given diagram, after which we must send the resulting assembly for milling. As the basis of the clamp, we take a steel strip measuring 1.6 by 8 cm. We also mill its front edge at an angle of 45 degrees.
To prevent deflection of the clamp, we reinforce it in the upper part with a corner sixty using welding.
Step No. 6: implement the fastening system
You can fix the device with clamps. But then, if at least one of them breaks, then the work will immediately stop, since the machine will begin to bend not the part, but lift itself.
Therefore, I propose an alternative and more practical solution:
- We extend the support beam beyond the edges of the table;
- We create U-shaped eyes on its edges;
- We screw it to the table with M10 bolts.
Step #7: Putting everything together
And here I present to your attention a drawing of the final assembly:
Conclusion
You have learned how you can make a machine for bending sheet metal at home, and why it is even needed. The video in this article contains additional materials, and in the comments you can ask any questions on the topic.
This publication presents the development of a homemade sheet bender, which was built by a YouTube channel blogger Hot master. In his video tutorial, the master will show a sheet bending machine of his own production, designed for processing rolls of endless sheet iron. It is end-to-end and you can stretch an as long ribbon of painted metal through it as you like. This machine can be used for bending galvanized iron and other metal up to 2 millimeters thick. If the thickness is 2 millimeters, then the length of the fold cannot be more than 30-40 centimeters.
Drawings for this bending machine were found on the Internet.
The presented machine is made of channels and angles. The corners are welded into a box. This is the worker node. The clamping bar is also made from corners welded together into a box. The sheet is clamped on 2 sides, on which clamping screws are installed. However, as experience has shown, it is enough to limit oneself to one side. Valve springs are installed between the working bodies into which the sheet is clamped so that the clamping bar rises freely when the clamp is loosened.
The rotating mechanism has hinges installed. The rotation angle is more than 90 degrees. The handle is made of a shortened hardened rod and does not interfere with the worker’s movement. The iron sheet can be installed both in front from the worker’s side and from the opposite side. The lever is located horizontally, which creates additional convenience when the worker does not need to bend down to grab the handle. In addition, the surface created by the handle can be used to feed sheets into the machine. If desired, you can install an additional table on the lever, creating a flat working surface.
The opposite clamp does not have to be a quick adjustable one, it can be a simple nut that can be turned occasionally to adjust the gap.
How work works on this sheet bending machine.
After the sheet is clamped, the lever rises and with a slight movement the bend occurs. By changing the angle of the handle, you can adjust the depth of the bend. If you need to bend a full corner, then, accordingly, the lever rises more. The result is a completely smooth and straight bend. If the bending is carried out with a reserve, then the result will be even more even. The work doesn't take much time.
At the back there is a table from which the iron is fed, it is convenient to cut off the excess.
The machine can be disassembled, for example you can remove the table. The entire bending machine is disassembled into parts, so it is easy to move. When disassembled, it easily fits in the trunk of a Volga car.
Explanations on the design of the sheet bending machine
Separate sheet bending units with comments. The machine has been in use in the workshop for a long time and has shown very good results. The most basic part is the clamp. This is the device that presses the sheet of iron to the base. The better and more accurately this is done, the better and smoother the bend will be. The clamp is made from corners welded together.
The work table or base of the sheet bending machine consists of one piece. This is a channel. The longer the workpieces, the more powerful this channel should be. In this case, its length is 1.5 meters. If you plan to bend workpieces 1.5 times larger, then the channel should be installed twice as powerful.
All the main work is done using a bending bar. A massive bending lever is welded to it. The bending bar is mounted on hinges that are cut in a special way. It directly bends the iron to the desired angle.
It is recommended to orient the bending bar together with the lever so that it is horizontal. In this case, the lever should be at waist level. On many factory sheet bending machines, the lever hangs down vertically, which creates great inconvenience during operation. You have to bend down and pick it up from below each time. It is much more convenient to push from chest level, which is especially important for large volumes of work.
The lifting clamping device is a set of springs from the cylinder head of a passenger car, along with washers, rings, to center the entire device on the threaded rod. It not only presses the clamping bar, but also lifts it to the position when the upper wing nut is pressed to the desired lift level. If you leave the wing nut, the bar rises and is at a certain height. Hinges - hinges are ordinary garage hinges. The hinge should fit into the groove all the way to its axis. The axis should rise from the base by no more than 2 millimeters. The level of pressure is adjusted by a thumb, which is tightened on a pin, pressing the bar against the sheet of iron. Under the wing there is a nut to which a 6 mm wire is welded, forming a lever.
The indicated shape of the lever has been verified by a large number of works performed with its help. A large nut is placed on the stud, which is loose and not threaded. Next, put on the washer from the block head. Under no circumstances should small threads be placed at the top. It should be taken into account that if you make the lever extending horizontally from the nut, it will interfere with working with some types of workpieces. Therefore, it is better to make the form shown in the video. If you make a flywheel with two handles, as shown in some drawings, this shape will interfere with inserting and removing the workpiece.
The length of the hairpin must be adjusted. It is necessary to ensure that the thread fits completely when the thumb is turned away to the upper maximum position. So that your fingers and palms can fit at least halfway into the clamping bar. What height of lifting level of the clamping bar is required?
Bending machine drawings
Is it possible to make a box using a sheet bender?
Suppose you have a piece of galvanized steel from which you need to make a box. Skeptics believe that this is not possible with this device. However, this is not the case if we use this model. Moreover, with its maximum length equal to the width of the working machine. And the height of the sides is practically not limited by anything at all.
First, watch the video to see how the whole process will happen. Next, the master explains the theory behind this for large boxes.
The most important thing is to correctly mark the future product. Let's assume that we conditionally need a box with sides of 5 centimeters.
To do this, we must set aside 5 centimeters from each corner. When the marks are ready, we connect them with the previously marked marks in order to make it easier and more accurate to make the necessary cuts and not cut everything out, but leave a little in order to bend, rivet or spot weld.
When the markings are ready, we need to make cuts. Since everything will be done using electric resistance welding, it is advisable to leave the outlets. That is, the master leaves tentative cutting lines. The selected parts will remain on the workpiece, that is, they will not go to waste. And the shaded parts will go to waste.
Another example of development
Homemade made of black metal. The base is a 12-gauge channel, a hinge is welded to it, and a 16-gauge pipe. A rod is embedded into the bending roller. It was all welded. The lever is made of a reinforced design. The bending beam is made of 75 angles. Half of the shelf has been cut off. The pressure beam is made of 75 angle and reinforced on one side with 50 angle. Additional emphasis was placed, since the beam in the middle was arched. Along the edges there is an eyelet from 75 angle, a bolt, and valve springs. A primitive eccentric has been made.
Where do they get metal parts of various shapes? The answer is that they buy them ready-made or make them themselves. Finished metal parts are much more expensive than the cost of a metal sheet, and to make them yourself, you need a special machine. You can make a sheet bending machine with your own hands, having some tools, materials and, of course, those same “golden hands” available. The videos and drawings presented in our article will also be useful to you.
Isn't it easier to buy a sheet bending machine?
The most pressing question is sheet bending machine price. The cost of factory sheet bending equipment is high. Such an expense is only advisable if you purchase such a machine to earn money, otherwise it will not pay for itself.
In addition, most of the machines of this type are designed to bend sheets up to 3 m wide. Such a unit cannot be called universal, firstly, it will not fit into any garage, and secondly, the mechanical drive is inconvenient for delicate work, and hydraulics complex and expensive. Thirdly, the energy costs for manufacturing small parts are not worth it.
The only option left is with a manual drive, which you can make yourself!
The simplest do-it-yourself sheet metal bending machine
Building a homemade manual sheet metal bender will save you money and will be a real boon whenever you need it. deal with sheet metal. Fortunately, you can find a variety of drawings with descriptions on the Internet. All offered models are different, but you can find something common in the design of all variants of any sheet bending machine:
- Clamp;
- Crimping punch;
- Lever handle;
- Grounds.
By the way, all parts do not have to be made of metal, You can also use wood. The wood is strong enough to process thin aluminum or iron sheets. Ordinary wood for this, of course, is a bit soft; it is better to take hard wood like oak, ash, walnut, etc. But as a last resort, pine material is also suitable for the simplest garage sheet bending machine.
As a basis take the presented drawings:
- We strengthen the tree with metal corners or sheets of metal;
- Where real strength is required are the hinges for the machine, with the help of which its bending link moves;
- If the bending link is a decent size, then you won't even need a weight frame to apply the required pressure to the thin sheet of metal;
- The crimping punch should be fixed with wing nuts, the main thing is to put washers under them;
- To work with sheets of different thicknesses, you can make blanks of several punches with grooves of different thicknesses;
- To bend metal sheets at 90 degrees, you need to equip a limiting surface with an inclination of about 5 degrees. Otherwise, it will be impossible to make a perfectly right angle.
Secret! To make precise bends, you need to make a notch at the intended bend location, which will direct the process in the right direction.
Do-it-yourself manual sheet bender for thick sheets
For the manufacture of parts from thin sheet metal, the simplest option made of wood and a minimum of metal elements will do. Whereas for processing thick sheets, powerful channels and angles will be needed. The design elements are the same as in the previous bending machine: base, clamp, lever and crimping ram.
Materials
Material for manual sheet bending:
- Channel No. 6.5 or No. 8 is suitable for the base;
- For clamping we take channel No. 5;
- For the punch you need a corner No. 5 with the thickest walls;
- For a lever handle, fittings with a diameter of 15 mm are suitable;
- 10 mm rod, sheet metal for the “cheeks”.
Although the design does not differ in principle from the first option, you cannot do without a welding machine.
Sequence of work
Let's get started with the work:
Final processing of parts
Some people recommend simply going over the clamp with a file or, even more outlandishly, with a grinder. However, you must be aware that such processing of the clamping plane will not give ideal accuracy - acceptable The unevenness of this element is only 0.2 mm. You cannot achieve such precision with a file, and if the processing is poor, your sheets will be wavy after bending.
This will still work for home use, but if you decide to do any work professionally, then this is unacceptable. There is only one way out - to send the clamp for milling, but this must be done after final assembly. When all the nuances that could appear have already appeared, then milling will really help to even everything out to a decent result.
As you can see, wonderful manual sheet metal bending machines can be made in a garage. Choose the option you need and do it yourself simple machine for thin metal l for a more serious machine made of channels and angles for working with thick sheets. Drawings with step-by-step descriptions and a video master class will help you. We advise you to heat the sheets at the bending points to make the work even faster and easier.
Various sheet bending operations are an important part of the general work on building or renovating your own home. Without the use of special equipment, it is impossible to perform them efficiently. For one-time bending of sheet blanks, it is permissible to rent a suitable device from a neighbor or friend. But if such procedures are often performed, it is more advisable to have a manual sheet bending machine of your own making on hand. If you have certain skills, tools and space, making a homemade sheet bender is not so bad.
Drawing up technical specifications
Thanks to the capabilities of the Internet, you can quickly find the required set of drawings, and on the YouTube channel you can even watch advertising and informational videos about the device and operating principle of the required unit. However, all these materials are strictly individual, and therefore were intended by their authors for specific sheet-bending operations. Therefore, before building a sheet bending machine with your own hands, you need to make the right choice of its future technical characteristics. The main ones should be the following:
- maximum width of bent metal, mm;
- maximum thickness of the workpiece, mm;
- desired range of bending angles;
- overall dimensions of the mechanism (length, width, height);
- required bending accuracy.
The direct choice of the limit values of the listed parameters depends on the conditions of use of the machine that will bend sheet metal products. In particular, when constructing a roof, you will most likely have to deal with galvanized sheet or steel with a thickness of no more than 1 mm. When processing copper, an even thinner sheet or strip is often used, and when making fences and railings with your own hands, on the contrary, the thickness of the metal can be 2 - 3 mm.
When choosing the optimal width of a workpiece - sheet or strip - you should proceed from the fact that the width of the part will rarely exceed 1000 mm (in extreme cases, adjacent workpieces can then be joined into a fold using the same machine).
The most difficult point in the technical specifications is considered to be the choice of the optimal range of metal bending angles. If everything is clear with the upper limit - 180°, then the lower value should be chosen very wisely. A natural consequence of bending most sheet metals in a cold state is springback - a spontaneous decrease in the actual bending angle due to the elastic properties of the deformed metal. Springing depends on:
How to choose the kinematic diagram of a bending machine
The most accessible machines for making with your own hands are machines in which sheet metal will bend as a result of turning a movable crosshead. The operating principle of such a machine is as follows.
The workpiece to be bent is installed on the guide plane of the lower table of the machine and fixed by a stop, which is fixed to the support frame of the device (it is advisable to provide for adjustment of the stop).
In the guides of the sheet bending frame, the upper traverse moves back and forth, which, when moving downwards, clamps the bent product with its ruler.
In front of the lower table there is a rotating beam that can rotate around its axis. The rotation can be done with a handle from a lever drive, but a version with a foot drive can be made. In the latter case, the operator’s hands remain free, which makes it easier to manipulate the workpiece when it is pressed against the ruler of the upper traverse. In addition, when operating a sheet bending machine using a foot, your hands get less tired.
The set of bending tools on the top and rotary beams may vary. The easiest way for this purpose is to order a set of punches and dies with the required bending radii and standard seats. You will have to send all the details with your order - ruler, clamp, etc. – which will require qualified milling work for their production.
The bevel of the top beam will determine the largest value of the bending angle by which the sheet metal can change its axis.
To make such a unit with your own hands, you will need the following materials:
- steel channel number 6 and above;
- a set of steel angles intended for making your own machine support frame;
- thick-sheet broadband steel from which the rotary, upper and lower beams will be made;
- assorted fasteners;
- rod for the manufacture of a manual lever drive for turning a beam.
To make work easier, you can also use a bench vice, guides from a decommissioned lathe, as well as massive hinges from steel entrance doors.
Using a similar principle, you can make a homemade sheet bender using wooden parts. True, it will only be able to bend aluminum and thin-sheet steel (up to 1 mm in thickness), but in many cases these capabilities are quite sufficient, and the labor intensity of building a sheet bending machine with your own hands will be noticeably reduced. In particular, there is no need for welding operations. It should be noted that the working parts of such a machine should be made only from hardwood (pine, spruce are not suitable).
Having decided on the operating principle of the sheet bender, you can look for suitable drawings. However, a person with an engineering education will be able to produce a set of drawings independently. The advantage of this option is that a number of working drawings can be quickly modified and processed to suit specific capabilities and source materials.
Drawings of the sheet bender must take into account the method of installation. For small units, for example, the bending machine can be mobile or even portable. Otherwise, you will have to use welding to make a stable base, otherwise excessive mobility of the machine will reduce the accuracy of work on it.
Once the machine is ready, it must be checked for functionality and accuracy. To do this, bend a test strip of thick cardboard of the required thickness. If the bending is performed correctly, then the height of the strip flanges will be the same, and there will be no traces left on its surface from the deforming tool.
