摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A guided keeper assembly and method for metal forming dies includes a base having a mounting face, at least one marginal fastener aperture to detachably mount the base to an associated die shoe, and a central guide aperture. A guide pin with a cylindrically shaped body portion 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 extending perpendicularly therethrough 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 and positively prevent the guide pin from rotating axially relative to the die pad.

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 self-contained stock lifter is particularly adapted for use in multiple station, progressive metal forming dies and the like, and includes a base plate with two vertical through holes adjacent opposite sides, and a vertical spring unit aperture located between the through holes. The stock lifter also includes a lifter bar having two vertical through holes in vertical registry with the base plate through holes. Two rigid guide shafts are mounted in the base plate through holes to permit the lifter bar to reciprocate in a manner which selectively lifts stock in the die to permit longitudinal shifting of the stock along the multiple die stations. A spring unit has a base retained in the spring unit aperture, and a reciprocating rod biased outwardly, with a free end abutting a central portion of the lifter bar to shift the lifter bar to an extended position, thereby defining a fully self-contained unit that can be readily mounted in and removed from the die to reduce manufacturing and repair costs.
