Document Type and Number:
Japanese Patent JPH0813387
Kind Code:
B2
Abstract:
A punch machining device for a plate is formed of a vertically movable upper die including a horizontally arranged punch holder with a large number of punches for punching the plate, a stripper plate vertically movably situated under the punch holder and having holes to allow the punches to pass therethrough and a returning device for urging the stripper plate in a direction away from the punch holder, and a lower die situated under the stripper plate to form a passage for the plate to be punched between the lower die and the stripper plate. The device further includes pressing heads installed on the punch holder for the respective punches, and pressing head driving devices attached to the respective pressing heads. Each pressing head driving device operates to locate a head part of the pressing head for immovably holding the punch against the punch holder or to locate a stepped part of the pressing head for allowing the punch to slide upwardly through the punch holder to thereby selectively activate the punch for making a hole in the plate. A control device may be installed for actuating the pressing head driving device in compliance with punching pattern so that desired pattern of holes is made in the plate in the punching operation.
