20150020663 | Multipunch With Axial Retainer For Securing Multiple Dies or Strippers - 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. | 01-22-2015 |
20140109742 | Punch Assembly With Separate Adjustable Punch Guiding Shim Block - A punch assembly for a hydraulic punch press machine that affords the ability to compensate for punch point metal loss due to resharpening by facilitating accurate repositioning of the punch point relative to an aperture in a stripper plate through which the punch point member projects during a stamping stroke of the punch assembly. | 04-24-2014 |
20130240615 | PUNCH ASSEMBLY WITH QUICK ATTACH PUNCH POINT AND STRIPPER PLATE REMOVABLY SECURE THEREON - A punch assembly for a turret punch press having a two piece reciprocally movable punch member that has a punch point insert removably attached to a punch driver that allows replacement of the punch point insert without the need to extract the punch member from its punch guide. A locking assembly comprising four vertical guideways containing slider strips for coupling the punch point insert to the punch driver ensures precision registration of the punch point insert with its driver. | 09-19-2013 |
20130199352 | Punch Assembly With Steel Punch Point Insert Removably Secured Therein - 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. | 08-08-2013 |
20130047808 | Punching and Forming Lubrication System and Lubricant Retention Matrix - A punch element is mounted for sliding movement in the guide sleeve or casing with the punch point at its lower end for forming or punching a workpiece. A stripper element is located at the lower end of the guide sleeve which defines the casing of the punch assembly, and the stripper element has an opening aligned with the punch point through which the punch point passes to engage the workpiece. A matrix placement chamber is provided within the casing between the punch point and the guide sleeve so as to at least partially surround the punch point and at least one flexible lubrication matrix body is contained in the matrix placement chamber inside the housing. The matrix which is enclosed entirely within the casing of the unitary punch assembly in which the punch reciprocates comprises an integral porous elastic multi-cellular polymeric body containing a multiplicity of hollow communicating cells adapted to hold a lubricant in fluid communication with the sidewalls of at least the point of the punch and in a preferred form completely surrounds the punch point. The lubrication matrix can also hold a cleaning agent or an abrasive in particulate form. | 02-28-2013 |
20120199642 | Multiple Punch and Die Assembly Providing Hand Disassembly, Punch Length Adjustment and Replacement - 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. | 08-09-2012 |
20100229701 | Multiple Punch and Die Assembly Providing Hand Disassembly, Punch Length Adjustment and Replacement - 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.
