FORGING METHOD AND FORGING PRESS FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a forging method which can form at forming speed suitable to a forming process and can prolong the service life of a die, and a forging press facility which adopts such forging method.;SOLUTION: In the forging press having dies for multi-processes, in which an upper die is fitted to a slide S, and supplying a workpiece W formed at the pre-process into the following process in order, the workpiece W is intermittently supplied so that a process for supplying no workpiece W exists, and thus, the formation is performed by adjusting the forming speed in each cycle into the speed according to the process, in which the workpiece W is supplied. If the workpiece W is supplied so as not to simultaneously perform the formations in the processes having large difference of the most suitable forming speed, the damage of the die and the deterioration of the formability caused by the forming speed can be restrained.;COPYRIGHT: (C)2008,JPO&INPIT
