There are mainly the following six methods of pipe bending in the pipe bending factory Stamping method:
Use a tapered core on the punch to expand the pipe end to the required size and shape.
Rolling wheel method: Put a core in the tube, and push the outer circumference with a roller for round edge processing.
Bulging method: one is to place rubber in the tube and compress it with a punch above to make the tube protrude into shape; the other method is hydraulic bulging, filling the middle of the tube with liquid, and the pressure of the liquid to bulge the tube into the desired shape. Most of the production of bellows uses this method.
Rolling method: Generally, no mandrel is used, and it is suitable for the inner round edge of thick-walled pipe.
Forging method: Use a swage forging machine to punch out the end or part of the pipe to reduce the outer diameter of the pipe. Common swage forging machines include rotary, connecting rod, and roller types.
Bending method: There are three commonly used methods, one method is called stretching method, the other method is called stamping method, and the third method is roller method. There are 3-4 rollers, two fixed rollers, one adjusting roller, and adjusting fixed roller. Distance, the finished pipe is bent.
