Abstract
A mounting plate (16) pivotally supports a finger (14) for pivotal movement about a pivot axis A as a shear pin (34) breaks between a post (30) and the finger (14) in response to a predetermined force urging the finger (14) to pivot about the pivot axis A. A first fastener (24) is disposed under an opening (46) in the finger (14) for removing the mounting plate (16) and the finger (14) together as a unit from the transfer bar (12) while remaining connected by a bolt (36) at the pivot axis A.
Claims36
A work piece transfer assembly for a press including a reciprocating member and a series of longitudinally spaced in-line stations wherein each station is a further progression of a work piece forming process, said assembly comprising:
- a transfer bar (12);
- a motion transmitting mechanism for moving said bar (12) inward, outward, and longitudinally for transferring work pieces through the press;
- a finger (14) for engaging and transferring work pieces through the press;
- a mounting plate (16) pivotally supporting said finger (14) for pivotal movement about a pivot axis (A) extending transversely to said transfer bar (12) with said finger (14) extending in a cantilevered fashion to a distal end for engaging the work pieces;
- first (24) and second (26) fasteners connecting said mounting plate (16) to said transfer bar (12);
- and
- a shear pin (34) having a first end supported by said mounting plate (16) and a second end disposed in said finger (14) for shearing in response to a predetermined force urging said finger (14) to pivot about said pivot axis (A);
- said assembly characterized by said first fastener (24) disposed under said finger (14) for removing said mounting plate (16) and said finger (14) together from said transfer bar (12) while connected at said pivot axis (A).
A work piece transfer assembly for a press including a reciprocating member and a series of longitudinally spaced in-line stations wherein each station is a further progression of a work piece forming process, said assembly comprising:
- a finger (14) adapted for attachment to a transfer bar (12) for engaging and transferring work pieces through a press;
- a mounting plate (16) pivotally supporting said finger (14) for pivotal movement about a pivot axis A extending transversely to the transfer bar (12) with said finger (14) extending in a cantilevered fashion to a distal end for engaging the work pieces;
- first (24) and second (26) fasteners for connecting said mounting plate (16) to the transfer bar (12);
- and
- a shear pin (34) having a first end supported by said mounting plate (16) and a second end disposed in said finger (14) for shearing in response to a predetermined force urging said finger (14) to pivot about said pivot axis A;
- said assembly characterized by said first fastener (24) disposed under said finger (14) for removing said mounting plate (16) and said finger (14) together from the transfer bar (12) while remaining connected at said pivot axis A.
