Have you ever learned about the hot push forming process of stainless steel seamless elbow?
The hot push forming of stainless steel seamless elbow mainly uses a special pushing machine, mandrel and heating device, so that the billet set on the mold moves forward under the push of the pushing machine, and is heated, expanded and bent during the process take shape.
Deformation characteristics of stainless steel seamless elbow:
The diameter of the tube blank is determined according to the rule that the volume of the metal material remains unchanged before and after plastic deformation. The diameter of the tube blank used is smaller than the diameter of the elbow, and the deformation of the blank is controlled by a mandrel, so that the compressed metal flow at the inner arc can be compensated to the extent due to expansion. Other parts that are thinned by the diameter, so as to obtain a seamless elbow with uniform wall thickness.
The elbow after hot push forming process has beautiful appearance, uniform wall thickness, can be continuously operated, and is suitable for mass production. This is also the main forming method for carbon steel and alloy steel elbows, and it is also used for certain specifications of stainless steel elbows. Head forming.
