Abstract
PURPOSE: To make possible the press blanking having no burr-form protrusions by embossing the work into the punch die hole of the resembling shape larger by the specified size than the die hole conforming to the part shape, thence striking it off by a punch thereby forming curved parts at the corner parts of both faces.
CONSTITUTION: The rolled work 1 is sandwiched by a die plate 2 and cushion plate 3 and the work 1 is embossed as a blank 1b into a die hole 2a by an embossing punch 4 slightly larger than the die hole 2a of the die plate 2 conforming to the part shape to form a curved face part 1c at the corner part. The slight clearance between the punch 4 and die plate 2 obviates the separation of the work 1 and blank 1b. Thence, the work 1 with the blank 1b is sandwiched by the plate 11 and die plate 13 in a separate process and the blank 1b is striken off into the die hole 12a by a punch 14, whereby a curved face part 1d is formed on the bottom surface. These make possible pressing free from burr production and yield the worked product of good quality from thin sheet-form material.
