Forging Process is one of the two components of forging (forging and stamping), in which forging machine is used to press metal billet to produce plastic deformation and Electric Power Fittings so as to obtain forging with certain mechanical properties, shape and size.
According to the way the blank moves, forging can be divided into free forging, upsetting, extrusion, die forging, closed die forging, closed heading forging.
1.Free forging. Use the impact force or pressure to deform the metal between the upper and lower iron (anvil block) to obtain the required forgings, mainly manual forging and mechanical forging two kinds.
2.Die forging. Die forging is divided into open die forging and closed die forging. The metal blank is obtained by compression deformation in the forging die bore of a certain shape, which can be divided into cold heading, roll forging, radial forging and extrusion, etc.
3, closed die forging and closed heading forging because there is no flying edge, the utilization rate of materials is high. It is possible to finish complex forgings with one or several processes. Since there is no flying edge, the forgings have less force area and less load required. However, it should be noted that the blank can not be completely restricted, so it is necessary to strictly control the volume of the blank, control the relative position of the forging die and measure the forging die, and try to reduce the wear of the forging die.
