The punch press of the present invention is capable of selecting three tracks of the punch tool by a standard and low-priced cylinder device. The tool setting station with punch tool is provided in the turret A that is rotatable around the center of the periphery. At least one of the tool setting stations is arranged with three punch tools in the turret diameter direction. The ram comprises the ram main body capable of elevating and descending, and the striker which is provided transferable in the diameter direction at the lower part of the ram main body. The punch press comprises the link member which is connected rotatable in both directions to the striker , and two cylinder devices A, B of which the piston rods A, B are connected rotatable to both ends of the link member.

Punch press

The present invention provides a tool centering mechanism for a punch press having a plurality of tools installed in juxtaposition and which can simultaneously be replaced with new ones, wherein the tool pitch of the tools can be adjusted to agree with the pitch of cooperating tools. A tool holder ( ) is provided on a first support ( ), the tool holder ( ) has a plurality of tool support sections ( ) spaced at a predetermined pitch and which can each support a tool ( ). The tool support sections ( ) each allow a tool ( ) cooperating with the tool ( ) in punching to be installed on its axis. In a punch press of the above construction, the tool holder ( ) and one ( B) of the cooperating tools ( ) can be moved relative to the first support ( ) and a second support ( ), respectively. Simulated punching is carried out to move the tool holder ( ) and the adjustable cooperating tool ( B) so that the cooperating tool ( B) can be installed on the axis of an associated one of the tools ( ) on the first support ( ).
