Title: Method for press forming
Inventor: KATSUMATA ISAMU
IPC: B21D22/20
Filed: 1980-09-17
Abstract: PURPOSE: To prevent linear discrepancies produced during the course of swaging  and bulging, by increasing deformation resistances by performing the primary working at the early stage of press forming process, and then, by performed the press  forming while parts to be worked are restrained.  
     CONSTITUTION: A crude material to be worked 5 is placed on a lower blank holder holder 3, and the crude material 5 is grasped by lowering an upper blank holder 4. Then, the material 5 is bent to a condition 6 at the early stage with a punch 1 and a cushion pad 7. After the deformation resistance of the material 5 is increased by this working, the punch 1 is lowered further while the material 5 is restrained with the punch 1 and the pad 7, and the press forming is completed so that the angular part 8 of the punch 1 will not slip out of the place where the angular part 8 initially contacted the material 5. When this method is applied, the bent angle 18 of the material 5 becomes smaller and the material will hardly move in the next press forming process, and, therefore, no linear discrepancy will occur.
