Medium frequency induction heating and pushing technology of elbow
Hot pushing elbow forming technology is to use special elbow machine, the mandrel and the heating device, make on the mould of billet in pushing forward movement, under the impetus of elbow machine in motion is heated and hole enlargement and forming process.Hot push bend deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter bend diameter, 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.
