Abstract
A punch press comprising (i) a tool set magazine that is located above a work table for supporting a workpiece and is juxtaposed with a main frame for supporting a punching head and (ii) a tool set delivery system for delivering tool sets between the tool set magazine and the punching head. A tool set mounting method comprising the steps of: (a) inserting the tool set delivery means into a tool set mounting section in a horizontal direction with a very small gap between the contact surface of an punch and its corresponding surface of the tool set mounting section opposite to the punch's contact surface and between the contact surface of a die and its corresponding surface of the tool set mounting section opposite to the die's contact surface; (b) lowering the tool set delivery means after the inserting step in such a direction that the small gap between the contact surface of the die and its corresponding surface of the tool set mounting section is eliminated; and (c) pulling the tool set delivery means out of the tool set mounting section in the horizontal direction after the lowering step while leaving the punch and die to be retained in the tool set mounting section.
