Closed die forging and closed upsetting part of forging two advanced technology, because there is no flash, material utilization is high. With a process or procedure may be completed several complex forgings finishing. Since there is no flash, forging forging force area is reduced model, the required load is reduced. However, you should be careful not to make the blank completely restricted, this should strictly control the volume of the blank, to control the relative position of the forging die and forging measure, efforts to reduce the die wear. Different methods have different processes forging, hot forging process in which the longest forging distributors, general order: By forging the blank; forging billet heating; blank roll forging equipment; die forging; trimming; punching ; correction; intermediate inspection, size and surface defect inspection and forgings; forging forging heat treatment type, to eliminate forging stress, improve metal cutting; cleaning up forgings, primarily to remove the surface oxide; correction; check to go through the general appearance and forgings hardness test, it is important to go through forging chemical analysis, mechanical properties, residual stress testing and nondestructive testing.
