1. Overview of cold extrusion (hot extrusion) forgings
Applying external force to the blank, causing it to produce plastic deformation to change the size, shape and performance, is used to manufacture blanks and forming processing methods for mechanical parts.It is the general term for forging and stamping.
Forging is the collective name of forging and stamping. It is a forming process that uses the hammer, anvil, punch or through the die of the forging machine to exert pressure on the blank to cause plastic deformation to obtain the required shape and size of the workpiece. .
2. Classification
Forging is mainly classified according to the forming method and deformation temperature.According to the forming method, forging can be divided into two categories: forging and stamping; according to the deformation temperature, forging can be divided into hot forging, cold forging, warm forging and isothermal forging.
