Many products are made from sheet metal - drainage systems, shaped parts for roofing, covered with a professional flooring or metal tile, fed for base, corners for structures from the professional leaf, etc. All this can make a special bending machine - for sheet metal. How to make a listogib with your own hands and let's talk in this article.
Types of sheet bibs
There are three types of sheet bending machines:
- Simple manual, flexible metal in which occurs when the power is applied in a certain place. These aggregates make it possible to bend the sheet material in a straight line at any angle - from several degrees to almost 360 °.
For flexible sheet metal
- Hydraulic machines in which the sheet metal bend is bent along the form of the matrix. The matrix can be straight, can be curvilinear. This is professional equipment, used in medium and high power enterprises.
- Roller or rolls. In them, the metal sheet is not flexible in a straight line, but spinning. With this equipment you can make the pipe or other similar products.
To obtain the radial bending of the metal sheet
All these devices refer to sheet bending machines. With your own hands, the unit of the first group is easier to make, slightly harder - the third (rollers for sheet metal). That's what we'll talk about them - from how to make leafogib do it yourself.
Simple manual
Shaped metal details are a lot of money. Even more than professional flooring or metal tile, therefore it makes sense to make the simplest machine for flexible sheet metal, and with it to make so many angles, swells and other similar details, how much you need, and exclusively under your sizes.

Another model
If you are worried about the appearance, then in vain. There is a leaf metal today not only galvanized, but also painted. In all designs, a sheet is fixed tight, so when working does not slide on the table, which means that the paint does not erase and does not scratch. In the bend places, it is also not damaged. So the view of the products will be quite decent. If you try, it will look even better to look like what they sell in the market.
Powerful sheet bending
For this, the leaf bending machine will require a smooth surface (table), preferably metallic, three corners with a width of the shelf at least 45 mm, a metal thickness of at least 3 mm. If you plan to bend long blanks (more than meter), it is desirable and the shelves are wider, and the metal is thicker. You can use brands, but it is for flexible sheet metal sheets of large thickness and length.
Metal door loops will also need (two pieces), two large diameter screws (10-20 mm), "lames" on them, spring. We still need a welding machine - to spend the loops and make holes (or drill with a metal drill).
For improvised leafogib, a brand of 70 mm was used - three pieces of 2.5 m, two bolts 20 mm with a diameter, a small piece of metal with a thickness of 5 mm (for cutting forcein), a spring. Here is the procedure:
- Two brands are folded, from two ends cut into them under the loop of the excavation. The edges of the recesses are mounted under 45 °. The third brand is covered in the same way, only the depth of the excavation makes a little more - it will be a clamping plank, so it should walk freely.
Cut out the recess under the loop
- Welcome loops from two sides (peak from the face and from the inside).
Weganing well a loop
- To one of the brands (distant from you, if you "reveal") are welded two bodies on each side. They are needed so that you can set the clamping plate on them.
Such drives
- To the bolt bolt nut.
We weld the nut
- Install the clamping bar (third cropped brand), at the top of the weld metal plates with a hole in the middle. The diameter of the opening is slightly more than the diameter of the bolt. To center the holes so that they are with a welded nut on one vertical. Spear.
Center, weld
- Spring cut off with such a calculation so that it raises the clamping bar by 5-7 mm. Skip the bolt in the "ear" clamping plank, put on the spring, spin the nut. After you installed the same spring on the other hand, the clamping bar when unscrewed the sama is risen.
Little things remained
- To the screw of the screw of the screw, two segments of the reinforcement - as a knob for twisting.
To a bolt hat to quickly cut fittings
- To the moving (neighbor to you) Tavra to welcome the handle. Everything can work.
Homemade Listogib in the Process
This option is very powerful - you can bend long blanks and a sheet of solid thickness. Not always, such scales are in demand, but can always reduce. The video provides a similar design of a smaller size, but with another fastening of the presser plank. By the way, no one bothers the screw too to install the spring - it will be easier to raise the bar. And this design is interesting to the fact that you can make flashes on it that usually such devices do not know how.
From a corner with a clamping plate of another type
This model is welded from a thick-walled corner, the bed is made as an ordinary building goat, which is welded from the same corner. Handle - from the luggage trolley. An interesting design of screws - they are long, the handle is bent in the form of the letter "g". Convenient to unscrew / twist.
Small manual leaf bending for self-making
In this homemade machine for flexible sheet metal there are many features:
- Corners are located not by the shelves to each other, but are directed in one direction. Because of this, the loop fastening is not the most convenient, but you can do.
Features
- On the bend of a long-range (still) corner of welded on both sides, small plates-stops for the presses.
- On the same bar welded nut from the screw (from two sides).
Clamping Planck
Now we turn to the design of the presser plate (in the photo above). It is also made from the corner, but stacked on the machine bending up. In order for the work at work, the reinforcement is not curved, the reinforcement - jumpers from the metal. From both ends, the planks are welded small metal platforms, in which holes under the bolts are drilled.
Another important point is the face that is addressed to the seal of the bend is cut - to obtain a more acute bend angle.
Planck is installed
The clamping strap is placed on the machine, the plant is placed in the installation site. The handle is installed in place. If it does not presses the bar, the springs are raised over the surface due to the strength of elasticity. In this position under it, the workpiece is filled, exhibit, pressed.
Under the hole put the spring, then - bolt
Not bad option for home use. Thick metal will not be able to bend, but tin, galvanized - without difficulty.
Rollers for sheet metal or roller sheet bending
This type of leafogib can have three types of drive:
- manual;
- hydraulic;
- electric.
With their own hands make rollers for sheet metal with manual or electrical drive. There are 3 shafts in manual, there may be 3-4 in their electric, but usually three.
Roller sheetogib
For this, the machine is needed a good reliable basis. It can be a separate bed or some kind of workbench or table. The basis of the design - rolls. They do the same size. The two lower ones are installed stationary, the upper is moving, so that it is located between the rollers at the bottom position. Due to the change in the distance between the lower rollers and the upper changes, the radius of curvature changes.
Move the machine with the help of a handle that is coming to one of the shafts. Next, the torque is transmitted to other rollers through asterisks. They are selected so that the speed of rotation is the same.
If it is assumed on the equipment to make pipes, the upper rink on one side is removable, with a quick fixation system. Running a sheet into a pipe, not to pull it differently.
