摘要： A punch system or assembly includes a punch body and a punch tip or insert with a working end and a stem configured for selective engagement and disengagement within a cavity in the punch body. A latch mechanism which can be operated without tools is configured to engage the punch tip stem within the axial cavity in a closed position, and to disengage the punch tip from the punch body in an open position.

摘要： A multiple punch and die assembly body member has dies or strippers that are held within multiple pockets in a multipunch body member by means of a centrally positioned retaining member formed from a rigid or flexible material located in a central recess at the middle of a ring of the surrounding dies or strippers. The retaining member is preferably held in place by a push plate that can be secured to the multipunch body member by a tightening element, e.g., a screw fastener for pressing the peripheral surface of the retainer member into engagement with the dies or strippers to hold them in their respective pockets in the multipunch body member.

摘要： A punching tool has a guided, axially displaceable die plunger 12, which is fixed against relative rotation, in a guide bushing 10. In a bore in its front end a punching die 22 is seated. During the punching stroke the punching die rests against a front face of the die plunger and is axially fixed in place by means of one or several snap-in balls 32, each of which is seated in a transverse bore 30, which snap-in balls are maintained in engagement with an annular groove 34 by means of a spring washer 36 in the die plunger. The outer diameter of the spring washer is only slightly less in the engagement position than the inner diameter of the guide bushing and can be elastically widened for releasing the punching die outside of the guide bushing.

摘要： A multiple punch and multiple die assembly has a workpiece protector comprising a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece.
