Cold forming elbow machine

Elbow pushing method has cold pushing process, hot pushing process, mainly corresponding to the pipe fitting machine and pipe fitting equipment have intermediate frequency elbow machine, cold pushing elbow machine, elbow pushing machine and other hydraulic elbow machine. After will push system on the tube billet blanking, upper and lower mould, pipe about advancing the mold core make it fall off after bend forming, with hot bend driving method is fast by using medium frequency induction heating pipe, improve its plasticity, using two step hydraulic propulsion, horn mandrel bending hole diameter, push the smaller the diameter of the tube billet made from large diameter bend forming process, the hot pushing craft production efficiency is high, the product specifications, production process continuity is strong, easy to mechanization production, is the existing various kinds of pipe bending process is a kind of economic and effective, has become the main method of the current production of elbow.
