摘要： A guide pin assembly includes a guide pin body that connects to a die component using retaining rings. The guide pin assembly has an upper and a lower retaining ring that permits the retention of the guide pin body in a hole in a component of a metal forming die, with each retaining ring contacting a surface of the die component. The guide pin body includes an opening to permit the temporary insertion of a device for positioning the guide pin body within the opening in the die member.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A guide pin assembly for metal forming dies includes a cylindrical guide pin body with a tapered guide pin head to guide associated die members from converging and diverging positions. A base is used to secure the guide pin assembly to one of the die members in a reciprocating die. The base includes a tapered surface that coincides with the tapered surface of the guide pin head to transfer the directional force, caused by the diverging die members, on the guide pin assembly to other die components. The guide pin assembly includes additional dampening components between the guide pin assembly and the base to dampen the impact caused by the diverging die members.

摘要： 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.
