What are the different forming processes for stainless steel seamless elbows?
There are mainly five common forming processes for stainless steel seamless elbows:
1. Forging process: Use a forging machine to punch the pipe end or part to reduce the outer diameter.
2. Rolling process: Place a core inside the tube and push the outer circumference with rollers for round edge processing.
3. Stamping process: Use a tapered core on a punch to expand the pipe end to the required size and shape.
4. Bending forming process: The bending forming process is divided into three common methods (① stretching method; ② stamping method; ③ roller method: there are 3-4 rollers, 2 fixed rollers, and 1 adjusting roller for adjustment and fixation. roller distance, the finished pipe fitting is curved)
5. Bulging process: ① Place rubber inside the tube and compress it with a punch above to make the tube bulge and shape. ② Hydraulic bulging, the middle part of the tube is filled with liquid, and the liquid pressure bulges the tube into the required shape. Suitable for corrugated pipes.
