  • Patent number: 7971468
    Abstract: A transfer assembly (22) for moving a work-piece (26) between stations of a hydroforming and/or hydrotrimming assembly. The transfer assembly (22) includes left and right posts (40, 42) spaced from and parallel to each other and extending vertically. A left top arm (56) and a left bottom arm (58) and a right top arm (62) and a right bottom arm (64) extend in spaced and parallel relationship with each other transversely to the posts (40, 42) to distal ends (60, 84). An upper rail (80) extends between the distal ends (60) of the top arms (56, 62) and a lower rail (82) extends between the distal ends (60) of the bottom arms (58, 64). The rails (80, 82) each include a plurality of part grabbers (86, 88) for engaging the work-piece (26). A transfer module interconnects each arm with the associated post for moving the arms (56, 58, 62, 64) vertically up and down and for moving the arms (56, 58, 62, 64) in and out.

  • Patent number: 7007538
    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.
