  • Publication number: 20180318905
    Abstract: A guided keeper assembly and related method includes a cylindrical base that mounts to a die member using a multi-piece, interlocking flange. The flanges have outer fastener holes and inner arcuate walls that matingly engage a complimentary profile on the outer surface of the base to axially interconnect the same. The flanges also have male and female end connectors which snap lock together around the base in an assembled condition. Mounting screws pass through the fastener holes in the flanges and are anchored in the die member to securely retain the guided keeper assembly in place. A retainer ring is mounted in an associated groove in the base over the heads of the screws to prevent unintentional unfastening of the screws from the die member.

  • Publication number: 20180297101
    Abstract: A guided keeper assembly includes a base, at least one marginal fastener aperture to detachably mount the base to an associated die shoe, and a central guide aperture. A guide pin is closely received in the central aperture of the base. A first end of the guide pin has an enlarged head to positively limit travel between the die shoe and die pad, and an opposite second end with a generally flat terminal shoulder configured for close reception in a blind hole in the die pad. The shoulder has a fastener aperture at a location spaced radially offset from the central axis of the guide pin. A fastener extends through the fastener aperture in the die pad and engages in the fastener aperture in the second end of the guide pin to securely, yet detachably, connect the second end portion of the guide pin with the die pad.

  • Patent number: 10099270
    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: 20180149184
    Abstract: A collar and shaft assembly utilizing a ring and a multi-stepped groove. The multi-stepped groove permits the ring to be compressed into one groove while the collar is being assembled and then to expand into a different groove that permits the ring to contact surfaces on both the collar and the shaft.

  • Publication number: 20180141106
    Abstract: A pilot assembly and method has a cylindrical pilot body with a tapered outer end, a grooved inner end, and a central portion with at least one inwardly curved side wall relief, as well as internally mounted reciprocating ejector pins with outer ends that protrude through holes in the outer body end to strip stock from the pilot. A spring has its outer end mounted in the groove in the outer body end, and an inner end attached to the inner body end in a pre-tensed condition. A cap screw has an enlarged head that has at least a portion thereof fit into the pilot sidewall relief, and a threaded shank that anchors the pilot in an associated die member.

  • Publication number: 20180009021
    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: 9737923
    Abstract: A stock ejector assembly and method for metal forming dies includes a stock ejector with a large spring and a ring-style stripper. The ring-style stripper provides a larger surface area for contacting the stock. The large compression spring is preloaded and when a load is applied, the stripper retracts and the spring pressure increases. When the dies separate, the stock ejector pushes the part off flat surfaces, separating surfaces sealed by adhesion, including, but not limited to, oil or lubricant adhesion.

  • Patent number: 9694411
    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.

  • Publication number: 20160288190
    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.
