  • Patent number: 8746029
    Abstract: A gas spring mount and related method for metal forming dies includes a one-piece, split clamping ring having a generally ovate plan shape with two spaced apart axes of symmetry. A generally circular clamping portion extends around the first axis, and is shaped to receive a gas spring body therein. A hook-shaped end extends around the second axis, and is shaped to receive a tapered head mounting member therein. A resilient free end is located operably between the clamping portion and the hook-shaped end portion, whereby tightening of the mounting member shifts the hook-shaped end outwardly and the free end inwardly to constrictingly pull the clamping ring securely against the gas spring body, and contemporaneously attach the assembly to an associated die member.

  • Patent number: 8733147
    Abstract: A gas spring mount and related method for metal forming dies includes a one-piece, generally U-shaped clamping band with an arcuate medial portion shaped to receive an associated gas spring body therein, and two enlarged ends with through apertures. Threaded mounting screws extend through the through apertures in the clamping band ends, and are anchored into threaded retainer holes in an associated die member. At least one of the mounting screws has a tapered head and is disposed laterally offset from the associated threaded retainer hole in the die, whereby tightening of the one screw shifts the related enlarged end of the mounting band laterally toward the opposite enlarged end to pull the clamping band constrictingly against the gas spring body to securely, yet detachably retain the same therein.

  • Publication number: 20140076107
    Abstract: A two-piece guide pin for metal forming dies includes a guide pin body formed from a cut length of an elongate, solid bar of stock having a cylindrical shape and a hard and smooth finished exterior surface with an outside diameter selected for close reception and reciprocal motion in an associated die bore. An alignment member is formed on a first end of the guide pin body. A guide pin head is formed from a cut length of an elongate, solid bar of stock having an outside diameter that is substantially greater than that of the guide pin body, and is rigidly connected with the second end of the guide pin body in a generally concentric relationship to define an enlarged head that positively limits travel between an associated die shoe and die pad.

  • Publication number: 20140047894
    Abstract: A pilot assembly and method for metal forming dies has a generally cylindrical pilot with a stripper that strips stock from the pilot when metal forming dies diverge. The pilot assembly is secured to one die member by a fastener by itself or in combination with a window mount. A spring within the pilot assembly contacts the stripper to force the stripper to reciprocate when the dies are pulled apart. Thus, the pilot assembly helps locate the stock within the metal forming die while also having a stripper to help strip the stock from the pilot.

  • Publication number: 20140013816
    Abstract: A guide pin assembly for metal forming dies includes a cylindrical guide pin body with an external retainer groove adjacent one end thereof in which a retainer ring is received. An annular guide pin ring with an outside diameter greater than the pin body, has a counterbore adjacent the outside end thereof and a retainer groove in a medial portion thereof which receives the outer portion of the retainer ring to securely interconnect the pin body and the ring and thereby form an enlarged head at one end of the pin body which positively limits reciprocal motion between two associated die members. A circular guide pin head cap covers the outer end of the head ring, and includes a support collar that is closely received in the counterbore of the ring, and engages the retainer ring to securely hold the same in place.

  • Patent number: 8522595
    Abstract: A guided keeper assembly for metal forming dies includes a base having a mounting face and a fastener aperture to mount the base to an associated die shoe, as well as a central guide aperture. A guide pin having a central portion is closely received in the central guide aperture for precisely guiding reciprocal motion between the die pad and the die shoe. The guide pin has an enlarged head at one end which abuts the the-base to positively limit travel between the die shoe and the die pad, and a shoulder at an opposite end with an alignment mechanism that precisely locates the guide pin on the die pad. A fastener extends through the fastener aperture in the base to securely connect the same with the die shoe. Another fastener securely connects the second end of the guide pin with the die pad.

  • Publication number: 20130180308
    Abstract: A retractable stock guide has a stationary guide rail on which a retractable guide cap is operably supported. The guide rail and cap have two through holes at opposite ends through which two mounting studs extend to attach the stock guide to an associated die member. The holes in the guide cap are ovate, and the heads of the mounting studs are tapered, whereby tightening of the mounting stud shifts the guide cap relative to the guide rail from an aligned, retracted load/unload condition, to an inwardly protruding, extended run condition, wherein the stock strip is slidingly captured between two like stock guides and the mounting surface of the die. Two ball bearing guides can be substituted for the stationary guide rail.

  • Patent number: 8151619
    Abstract: A guided keeper assembly and method for metal forming dies includes a base having a mounting face, a connector portion and a central aperture. A guide pin has a cylindrical center portion closely received in the central aperture of the base for reciprocation, an enlarged first end with an alignment member, and an outwardly opening circumferential groove. A retainer ring is removably mounted in and protrudes radially outwardly of the groove to securely, yet detachably, retain the base on the guide pin between the enlarged head and the retainer ring in an assembled condition to facilitate transport and mounting of the guided keeper assembly.

  • Patent number: 8146399
    Abstract: A modular spring retainer and method for metal forming dies includes a base shaped for detachable connection with an associated die plate, having a threaded central aperture, and an adjacent lock dowel aperture which extends through the threaded central aperture to form a window. A cylindrically-shaped spring retainer is configured to receive a spring therein, and has a threaded exterior portion which engages the threaded central aperture of the base, such that mutual rotation of the same adjusts the longitudinal position of the spring. A locking dowel is closely received in the lock dowel aperture in the base, and has an unthreaded exterior surface which protrudes through the window and abuttingly engages an adjacent portion of the threaded exterior surface of the spring retainer to securely, yet detachably, retain the spring member in a selected longitudinal position.

  • Patent number: 8074486
    Abstract: A guided keeper assembly and method for metal forming dies includes a base having a flat mounting face and at least one marginal fastener aperture to detachably mount the base to an associated die shoe, as well as a central guide aperture. The assembly also includes a guide pin having a central portion closely received in the central guide aperture of the base for precisely guiding reciprocal motion between the die pad and an associated die shoe. The guide pin has an enlarged head at a first end thereof which abuts the mounting face of the base to positively limit travel between the die shoe and the die pad, and a shoulder at the opposite or second end thereof with an alignment mechanism that precisely locates the second end of the guide pin on the die pad. A first fastener extends through the marginal fastener aperture in the base to securely, yet detachably, connect the same with the die shoe. A second fastener securely, yet detachably, connects the second end of the guide pin with the die pad.
