Quite often, the farm faced with the fact that you need exactly bend any rod, metal plate or tube. And if it must be done perfectly accurately, it is necessary to look for a place where there is a rolling machine. And you are lucky if you have friends from the factory, or a friend who has a machine. You can get rid of these searches, if you can produce a primitive rolling machine at home, which can be said, going from scrap.
Understand what material you can make this device and how it will work.
In the manufacture of rolling machine from vise will need the following material:
- Automotive tension pulley with diameter of 60 mm – 2 PCs.;
- The bearing 302 – 2 PCs.;
- Metal corner 40 by 40 mm length 60 cm;
- A metal rod with a diameter of 15 mm and a length of 70 cm;
- Metal pipe with inner diameter 16 mm length 100 cm;
- A metal pipe with an inner diameter of 42 mm with a length of 20 cm;
- A metal pipe of an outside diameter of 14 mm and inner 10 mm long 105 mm;
- Bolt diameter 15 mm – 2 PCs+nuts on them;
- Washer with inner diameter 10 mm, thickness 2.5 mm – 6 PCs.;
- Bolt diameter 7 mm length 45 mm – 2 PCs.;
- Bolt M14 with a length of 7 cm;
- Metal plate width 3 cm, length 25 cm, 4 mm thick;
- A rod with a diameter of 7 mm which obviously need to cut a thread length of 13 cm.
And we will need the following tool:
- Wire Cup brush for angle GRINDERS;
- Set of drills;
- Step drill 4-20 mm;
- The welding machine;
- A set of taps.
Instructions for the Assembly of the rolling machine from the clutches of the steps
We clean the thin metal pipe to a Shine, and cut from it 4 bushing for 37 mm.
On the metal area also clean the rust and cut into two corner of the 180 mm.
Thick pipe with one hand, if it is possible do the rolling with a length of 45 mm, if not, you can make the risks of a normal grinder, but turn out not very nice.
Then drilled on one face of each corner hole with 4 mm diameter on both sides about 1.5 cm from the edges. These holes we need to start working speed drill, reams data hole to 16 mm.
Each sleeve exactly matching with our holes on the inside of the corner and put alternately on the bolts that would be convenient and smooth to weld. Weld.
To check fix the corners of the outer sides in a vise so the holes match, and watch it easy takes place in our bar. If the rod is not included finalizing the ratio of openings.
Without removing the part from the vise, drill two tap holes with a diameter of 7 mm on the top side farthest from us the area within 3 cm from the edges in the middle of the face width. With a tap cut threads in each hole. These places will stand the tension rollers.
On top of these holes and put on three washers and clips, fix bolts. If the adjustable long bolts washers.
Cut from the thick tube portion with knurling a length of 70 mm. press-fitted from the side of the rolling bearing, on the other hand put any sleeve length of 25 mm and put the second bearing in until it stops.
In the area without commercials on the free side in the middle of the drilled hole with a diameter of 13 mm and threaded with a tap. Fine washer plant tube with bearings risk to the bottom, fix the M14 bolt.
Cut two rods of 150 mm and each weld one side of the puck.
Now we need to make the handle for this device. Weld from the side without grooves for the large tube, the future the handle of the metal plate. Drilled with the free edge of the handle hole with a diameter of 7 mm, threaded
Screw the threaded rod into the hole in the direction opposite to the pipe with the bearings. As soon as the rod begins to exit through the plate, fix them by welding. Cut thin tube with inner diameter 16 mm, length 10 cm
Now to the rod with thread since the beginning, put on the thin tube, it is thicker. Inner tube protrudes by 5 mm, it put on any puck that would the outer tube is closed and fix with the nut. If possible, for aesthetics, you can paint the handle in any color. Collect the entire structure.
This device can easily bend various pipes, sheet steel, etc. under a certain radius, which will be regulated directly by the vise. As you can see from this article the device does not require complex operations and high costs, and where to apply it, the farm is always there!
