Carbon steel elbow forming process is the use of special elbow

　　Carbon steel elbow forming process is the use of special elbow push machine, mandrel and heating device, in order to achieve set in the blank on the die in the pushing machine driven forward, in the movement was heated, diameter and bending Forming process. Carbon steel elbow deformation is characterized by the volume of metal materials before and after the plastic deformation of the law to determine the diameter of the tube, the diameter of the tube used in less than the elbow diameter, through the core mold to control the deformation process, Of the compressed metal flow, complemented by the expansion of the thinning of the other parts, to get a uniform thickness of the carbon steel elbows.
