The elbow forming machine manufacturer, the hot push elbow forming process is to use a special elbow push machine, core mold and heating device, so that the blank sleeved on the mold moves forward under the push of the push machine, and is heated during the movement. The process of expanding and bending. The deformation characteristic of the hot push elbow is to determine the diameter of the tube blank according to the law of the constant volume before and after the plastic deformation of the metal material. The tube blank diameter used is smaller than the elbow diameter, and the deformation process of the blank is controlled by the core mold to compress the inner arc The metal flow is compensated to other parts that are thinned due to diameter expansion, so as to obtain an elbow with uniform wall thickness.
