How is the hot push elbow formed?

The hot push elbow forming process uses a special elbow push machine, a core mold and a heating device, so that the blank set on the mold moves forward under the push of the push machine, and is heated, expanded and bent during the movement. the process of. The deformation characteristic of the hot push elbow is to determine the diameter of the tube blank according to the law that the volume of the metal material does not change before and after plastic deformation. The diameter of the tube blank used is smaller than the diameter of the elbow. The metal flow is compensated to other parts thinned by the expansion, so as to obtain an elbow with a uniform wall thickness.
