Hot forming elbow machine

The forming process of hot push elbow machine is based on the working principle of using special medium frequency induction elbow machine, elbow push machine, core die and heating device to make the steel pipe and tube blank on the die move forward under the push of push machine, and be heated, enlarged and bent in the movement. Notes for elbow making: the diameter of pipe blank must be smaller than that of elbow, otherwise it will affect the wall thickness requirements of forming elbow. Reason is due to the deformation characteristics of the hot pushing elbow is according to the volume before and after plastic deformation rule of metal materials determine the pipe diameter, adopted by the medium frequency pipe billet diameter less than bend diameter of bend machine, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.
