Sharing of Several Forming Processes of Stainless Steel Seamless Elbow
The stainless steel seamless elbow is mainly used as the turning point of the pipeline. It has five forming processes. Let’s learn about it with Licheng? !
Wenzhou Licheng Steel Industry Co., Ltd. is a modern enterprise specializing in the production of stainless steel pipes, fittings and flanges. We have professional technical force and advanced team management skills. Brands include: 304.304L.304H.321.321H.316.316L.317L.310S.347H, etc.
Explanation of the forming process of stainless steel seamless elbow:
① Forging: use a swage forging machine to stretch the pipe end or part to reduce the outer diameter. Commonly used swage forging machines are rotary, roller, and connecting rod.
②Rolling: Place a core in the tube, push the outer circumference with a roller, and use it for round edge processing. Rolling generally does not use a mandrel, and is suitable for the inner round edge of thick-walled pipes.
③ Stamping: Use a tapered core on the punching machine to expand the pipe end to the required size and shape.
④ Bending forming: There are three commonly used methods, namely stretching, stamping, and rolling. There are 3-4 rolls, 2 fixed rolls, and 1 adjustment roll. Adjust the fixed roll distance. The finished product is curved.
⑤ Bulging: One is to place rubber in the tube, and compress it with a punch above to make the tube protrude; the other is to form by hydraulic bulging, filling the middle of the tube with liquid, and the pressure of the liquid will bulge the tube into the desired shape. Bellows production Most of them use this method.
