Have you ever learned about the processing methods of stainless steel seamless elbows? Generally, there are four common processing methods: rolling method, stamping method, bulging method and bending forming.
One rolling method
This method is manifested as: under normal circumstances, no mandrel is required, and it is suitable for processing the inner round edge of thick-walled tubes. Put a core in the tube and push the outer circumference with a roller for round edge processing.
Two stamping method
This method is manifested as: using a tapered core on the punching machine to expand the pipe end to the required size and shape.
Three inflation method
There are two forms of this method, one is to place rubber in the tube, and press it with a punch above to make the tube protrude into shape; the other is hydraulic bulging, filling the middle of the tube with liquid, and the pressure of the liquid makes the tube bulge into the desired shape. the desired shape. Bellows mostly use this method.
Four bending
There are three forms of this method, stretching method, stamping method, and roller method. There are 3-4 rollers, 2 fixed rollers, and 1 adjusting roller, which are used to adjust the fixed roller distance, and the finished pipe is in a curved state.
