ABSTRACT:
The punch is surrounded by a tubular housing carrying a stripper plate and having a hinged door which is latched closed unless the punch is retracted to a tool change position. In addition, means sense the position of the door and prevent automatic cycling of the punch if the door is not closed. To adjust the stripper plate vertically, provision is made of compactly nested threaded rings and, to orient the punch angularly, provision is made of an adjusting mechanism which acts on a rod projecting from the upper end of a hydraulic cylinder and connected to a downwardly projecting ram for reciprocating the punch.
