There are many processing methods for stainless steel elbows, many of which belong to mechanical processing. The most commonly used methods are stamping, forging, rolling, bulging, stretching, bending, and combination processing. The processing of stainless steel elbows is organically combined with metal force processing.
The following are the processing methods for stainless steel elbows:
1. Forging method: Use a forging machine to punch and stretch the end or part of the pipe to reduce the outer diameter. Common forging machines include rotary, connecting rod, and rolling wheel.
2. Rolling method: Generally does not require a core shaft, suitable for the inner circular edge of thick walled pipes. Place the core inside the tube and use a roller to push the outer circumference for edge processing.
3. Stamping method: Use a tapered core on the punch press to expand the tube end to the required size and shape.
4. Bending forming method: There are three commonly used methods, one is called stretching method, another is called stamping method, and the third is roller method, which has 3-4 rollers, two fixed rollers, one adjustment roller, and adjusts the fixed roller distance. The finished pipe fittings are bent.
5. Dilation method: One method is to place rubber inside the tube and compress it with a punch to make the tube protrude and form a shape; Another method is hydraulic bulging forming, in which liquid is filled in the middle of the pipe, and the liquid pressure swells the pipe into the desired shape. This method is widely used in the production of corrugated pipes.
The processing methods for stainless steel elbows mainly include the five methods mentioned above. You can choose the processing method that suits you.
