Title: Bending equipment for plate material
Inventor: OSUMI YOSHIHIRO
IPC: B21D5/01
Filed: 1988-01-14
Abstract: PURPOSE:To obtain a square external side and an irregular deformation on a surface part at one stage by providing a fine projection along a curve on a curved corner part of a worked surface of a punch and making a clearance between the punch and a die smaller than the thickness of a plate. CONSTITUTION:The plate material 15 is put on a recess part 16 of a reverse blank holder 14 and an edge part is positioned by a positioning material 18. When the punch 11 is lowered and comes into contact with the plate material 15, the projection X of the punch 11 encroaches upon the surface of the plate material 15, tensile force acts on the surface of the plate material 15 and the edge part of the plate material 15 begins rising. Further, the edge part is supported as it is contracted between the punch 11 and the die 12 and at the same time, bending works on the edge part, tensile force acts on the surface of the outside of the bend and the material is supplied from the part compressed by the rising edge part to the outside part of the bend. The concentration of the stress occurring in the plate material 15 can be reduced and, besides, residual stress can be decreased.
