When running large quantities of sewer pipes is good to have a pipe cutter. It allows cutting them quickly and immediately with a prepared chamfer easily passing into the bell. To save, the cutter can be done by hand.
- coupler 110 mm;
- the clamp 110 mm;
- sewer pipe 200 mm;
- square rod 10×10 mm.
- threaded stud M12;
- shaped tube 20×20 mm;
- PP pipe 20 mm;
- screws, nuts.
The process of manufacturing the cutter
On the coupling fits over the clamp with a twisted bracket.
Then from a sewer pipe 200 mm should be cut into 3 rings.
2 of them have a width of 4.5 cm, and 9.5 cm. one Ring are cut along.
One of the narrow rings is shortened and stretched on a greased clutch.
It is loaded to the second adhesive slim, cropped ring.
The third wide release is pasted with the outside of the clutch. For reliability on the seam of the last ring you need to solder the twisted wire heated.
Square rod to sharpen the cutter.
After this, take the stud in her butt drilled hole, which is tapped M6. Then screwed the screw with the threaded nut M8. Thereafter, the end face of the cutter is welded to the rotating of the screw nut.
Taking the length of the profile of the pipe 12 cm, have one end cut into her face at 4 cm Then the walls of the trimmed edges are bowed outwards at a right angle. On the straight end of the pipe is welded nut M12.
In a wide ring on the body of the cutter is cut a square hole in the side of the coupling. It is necessary to insert the cutter pin which is twisted in a bent core tube. Then eyes pipe bolted to the body of the cutter.
On the stud connected to the cutter breaks through the 3 nuts. One will work as a lock nut for fixing the blade depth, so tucks to the pipe profile. The remaining will serve as the holder of the handle. They need to heat and pull the plastic water pipe.
On of the studs is required to make a similar handle as the cutter. It is mounted on the clamp. Before that you will need to drill the wall of the coupling to the stud came inside her. If a regular nut of the clamp is not suitable, instead, you can weld M12, because the thinner the pin can bend under load.
To use the cutter, you want to put on the pipe. Then turn the knob on the clamp to lock it. Then lightly drawn in the cutter, and stick with it wrapped on a circle with periodic screwing. The principle of operation is the same as closing the key to the preservation of the workpieces.
