Abstract: A punching tool has a guided, axially displaceable die plunger, which is fixed against relative rotation, in a guide bushing. In a bore in its front end a punching die 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 each of which is seated in a transverse bore, which snap-in balls are maintained in engagement with an annular groove by means of a resilient ring in the die plunger. The outer diameter of the resilient ring is only slightly less in the engagement position than the inner diameter of the guide bushing and can be resiliently widened for releasing the punching die outside of the guide bushing.

Abstract: 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.

Abstract: A punch canister includes a punch head with an axial shaft that has a screw thread which is adapted to be connected during use to the screw threads of a punch element that is slideably associated within a stripper bushing. A punch recess adjustment member is rotatably and slideably associated with the punch head. The adjustment member is adapted to the slideably but non-rotatably rotatably connected during operation to the punch element. A resilient retraction member, e.g., a spring, is located between the punch head and the adjustment member for biasing the adjustment member axially downward on the punch head. A manually releasable detent provided on the adjustment member is operatively associated with the punch head for retaining the adjustment member in any one of a plurality of selected circumferentially distributed angular positions on the punch head such that during operation disengagement of the detent allows the adjustment member and the punch element to be threaded axially on the punch head to control the distance that the punch element is recessed within the stripper bushing. In a preferred form, the detent is a lock that can be disengaged manually when the punch recess adjustment is to be made.

Abstract: A punch assembly for punching or forming sheet metal has a circumferentially extending, horizontally disposed supporting flange that is slideably mounted upon the body of the punch assembly as a part thereof for supporting the punch assembly on a punch press. A resilient tool retractor, e.g., one or more springs is provided within the punch assembly for retracting or elevating the body of punch assembly relative to the supporting flange. Provision is also made for enabling a person to manually change the tool length and thus the feed gap from the exterior of the punch assembly by controlling the distance that the upper forming tool, i.e., the punch extends downwardly below the supporting flange and a lock is provided for securely retaining it in a selected position.

Abstract: A split ring alignment ring for holding a punch has a split ring by which the alignment ring can be tightened onto the punch shaft. The alignment ring has a pair of radially aligned cut outs, on its inner circumference and are on its out circumference. A pin on the tool shaft engages the inner cut out to fix the tool against rotational movement relative to the ring. A second pin projects axially from the top of a punch point of the tool to engage the outer cut out, also to prevent rotational movement relative to the ring.

Abstract: A punch press tool for stamping successive multicharacter impressions into a workpiece such as a piece of steel, sheet metal, or other workpiece, includes a guide body in which a stamp driver is slidably mounted for being driven downwardly toward the workpiece by a punch press ram which is a standard part of a high speed commercial punch press. A multicharacter marking stamp is supported at the lower end of the stamp driver for reciprocal movement therewith. The marking stamp includes multicharacter wheels that are rotated automatically during operation for advancing characters in sequence responsive to the movement of a character advancing arm. At least one character stamp operating lever is operatively associated with the punch press tool for articulation responsive to motion imparted to the tool by the ram. The lever has an operating element that is operatively associated with the character advancing arm of the multicharacter stamp for indexing the arm to enable successive characters thereof to be placed in an operating position responsive to a stroke of the punch press ram.
