摘要： A multiple punch and die assembly adapted to be placed in a punch press having a punch ram for imparting movement to a selected punch assembly for carrying out a punching or forming operation comprises a punch assembly for holding a plurality of selectively operable punches mounted for independent movement in the punch assembly so as to 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 by a pair of tabs located on a lower circumference of the striker body, said pair of tabs located on a lower circumference of the striker body with a radial separation other than 180 degrees. A circumferential lip in the punch carrier receives the pair of tabs and has corresponding radially separated reliefs for allowing the pair of tabs to pass the circumferential lip, the engagement of the pair of tabs by the circumferential lip thereby locking the striker body 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 in inactive. In another embodiment the assembly has a stripper retainer that has precision pockets for holding strippers corresponding to the selectively operable punches.

摘要： A stripper unit incorporates a precision threaded plug that preloads a mechanical die spring that, in turn, preloads the movable or traveling stripper adjacent the punch tip. The precision threaded plug simultaneously accurately locates the stripper unit on a commercially available ball-lock punch retainer. The stripper unit is entirely self-contained on the face of the ball-lock punch retainer, thus minimizing the space required on the press platen.

摘要： A retain-and-release member, which is coupled to a punch holder of a punch assembly, engages a punch tip against an end of the holder, such that a working portion of the tip extends from the end. A punch guide sidewall of the assembly includes an aperture aligned with an actuation interface of the retain-and-release member, when the punch holder and the engaged punch tip are slidably engaged within a guide bore formed by the punch guide sidewall. The aperture provides access for applying a force, to the actuation interface, in order to disengage the retain-and-release member from the punch tip, while the punch holder remains within the guide bore of the assembly. Following the removal, the same punch tip, or another, may be inserted into the guide bore and into engagement with the retain-and-release member.

摘要： 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.

摘要： A die stamping system includes an upper die, a sliding block, a lower stripper, a die holder connected to the lower stripper, and a lower die-set moveably connected to the die holder. The sliding block includes a body with a wedge-shaped head facing down, a punch connected to the body, and two arms on opposite sides of the body, respectively. The lower stripper matches the upper die-set and has an aperture for passage of the punch therethrough. The die holder is connected to the lower stripper and includes an opening for passage of the body therethrough, and a first notch receiving the two arms. The first notch is larger than the arms. The lower die-set is movably connected to the die holder and includes a wedge-shaped padding block facing up and supporting the wedge-shaped head of the body.
