Abstract: 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.

Abstract: A punch assembly for a turret-type punch press comprises an outer guide sleeve having an inner bore in which a punch shank fits for reciprocating but not rotating movement. The punch shank has a concentric, downward opening formed in a lower end in which is received a head portion of an insert that has a punch point formed on it. Built into the shank is a latching mechanism for releasably wedging and thereby securing the insert to the lower end of the shank.

Abstract: A multiple punch and die assembly adapted to a punch press for carrying out a punching or forming operation comprises a punch assembly for holding a plurality of selectively operable punches that selectively engage a workpiece. The punch assembly has a punch carrier for reciprocal motion within a punch guide and a striker body engaging the punch carrier, said striker body being selectively, toollessly connectable to the punch carrier while permitting relative rotation of the striker body and punch carrier to select a punch for engagement by the striker. A detent means releasably positions the striker body in one of a plurality of operating positions, at which a punch is positioned for being struck selectively by the ram via the striker body such that one punch is driven to an operating position when at least one other punch is inactive, the inactive punches engageable by a lock plate.

Abstract: A multiple punch and multiple die assembly has a workpiece protector as 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.

Abstract: A punch assembly for a punch press has a punch housing with a punch that is slideably mounted for reciprocation along punch axis within the punch housing and at least one resilient member in the housing for yieldably biasing the punch upwardly in the housing along the punch axis. A punch length adjustment subassembly is provided in the punch housing. The subassembly has a base member that is slideable axially but non-rotatably mounted within the housing and a punch head member having an upper end that is positioned to be struck by a punch ram of a punch press for driving the punch downwardly to an operating position. The punch head is mounted for rotation on the punch axis relative to the base member but is held against axial movement relative to the base member. The punch head is operatively associated by a threaded length adjustment connection to the punch and a releasable stop member is connected between the punch head and the base member for preventing rotation of the punch head relative to the base member while the punch assembly is in operation on the punch press. The invention is also directed to the punch head subassembly per se as a retrofit insert to update existing punch assemblies for manual tooless punch length adjustment and tooless punch removal.

Abstract: A tapping tool having a guide body, a driver for longitudinal movement of a tap within the guide body, and a pump for lubricating the tap. A keyway in the outer body of guide body mates with an indexing key in a rotatable indexing holder of a turret press, which causes the guide body to rotate in sync with the turret press. A driver cylinder is centrally disposed in the guide body. The driver is adapted for sliding, mating engagement within the driver cylinder. A chamber in the lubrication pump holds the lubrication which is ejected by the pump onto the tap. Lubrication is ejected onto the tap through a normally closed ejector inlet that is opened by downward movement of a plunge pin against the lubrication in the chamber. The ejector is sized to restrict the flow of lubrication from the ejector outlet, which creates back pressure in the lubrication chamber. The back pressure forces a ball to close the lubrication conduit when the plunge pin moves downward.

Abstract: A punch press alignment instrument has upper and lower cylindrical components that are associated for vertical displacement relative to one another. Both components have outer tool holder engaging surfaces which are to be aligned with one another so as to in turn align the tool holders of the punch press when the upper and lower components themselves are in alignment. Alignment elements, e.g., ridges and grooves provided on mating surfaces of the components confronting each other are brought into contact with one another to move the components of the instrument into mutual alignment. An alignment control member, e.g., a screw is preferably provided for progressively bringing the upper and lower components toward one another and an indicator such as a lamp, a dial indicator or an audible indicator is provided for denoting the spacing between the upper and lower components to thereby confirm the alignment of the tool holders. A releasable element is used to temporarily hold the upper and lower components apart when they are spaced laterally from one another or for any reason are not capable of being placed in alignment.

Abstract: A method and an apparatus are provided for marking a sheet-shaped workpiece using a marking tool. The marking tool is mounted in a punch holder of a punch press and a counter-support is fixed in place on a side opposite of a marking surface of the workpiece to be marked. The surface of the workpiece is marked by displacing the workpiece in its plane while engaging the marking tool with the workpiece. In one form, a support roller provides counter-support. In another form, an elastic element is cooperatively associated with the punch stroke of the punch press to translate an exactly defined contact pressure force between the tool tip and the workpiece to be marked.
