Precision forging, precision forging equipment and precision forgings

摘要

The precision forging method has a metal material (10) disposed in the die hole 22 such that the tip end surface of the peripheral wall (14) of the metal material (10) faces the stopper (24) and the bottom (12) of the metal material (10) faces the punch (30).In addition, the precision forging method moves the punch 30 having a cutting edge (32) at the edge of the processing end face (31) within the die hole (22), thereby cutting part of the thickness direction of the wall (14) by the cutting edge (32); The cut portion has a shear deformation.
