The use of steel pipe/tube processing methods

1. Forging method: Uses the type forging machine to be Takiko part or part to be extended, causes the outside diameter to reduce, the common type forging machine has

Rotary type, connecting rod type, wheel type.

2. Stamping method: The tube end is expanded to the required size and shape with taper core on the punching machine.

3. Roller method: In the Tube to place the core, the peripheral roller push pressure, for the round edge processing.

4. Rolling rolling method: The general use of mandrel, suitable for the inner edge of thick wall tube.

5. Bending forming method: There are three kinds of methods are more commonly used, one method is called stretching method, the other is called stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, an adjustment roll, adjust the fixed roll distance, finished pipe is curved. 6. Bulging method: One is to place rubber in the tube, the top with the punch compression, so that the tube protruding forming; Another method is hydraulic bulging forming, filling in the middle of the pipe liquid, liquid pressure to drum the tube into the desired shape, the production of bellows most of this method.
