Abstract: A connecting device connecting a remaining bar and a movable bar of a transfer bar includes a remaining-side clamp and a movable-side clamp. The clamps respectively have a male fitted portion and a female fitted portion that are fitted to one another around a connecting direction, defining a first connector. A male engagement portion and a female engagement portion are provided inside the clamps, defining a second connector. The female engagement portion of the second connector includes a sphere in a form of a movable member moving in a direction orthogonal to the connecting direction. A movement of the sphere effects an engagement and disengagement of the female engagement portion from the male engagement portion.

Abstract: A shiftable workpiece transfer apparatus for transferring a workpiece to a press while simultaneously shifting the workpiece centerline. Such a transfer apparatus includes cooperating workpiece transfer tables, the movement of which is directed by respective guide rails. A first workpiece transfer table is directed along a path that is substantially parallel to the centerline of the press line. The second workpiece transfer table is directed along a path that is skewed with respect to the centerline of the press line by an amount sufficient to produce a desired shift of the workpiece centerline. As the second transfer table moves along the skewed guide rail and toward the first transfer table, the workpiece is automatically moved across the surface of the first transfer table to a desired centerline offset point.

Abstract: A press die set for a multi-step press system includes a lower die attached to a table and an upper die attached to a ram, the lower die and the upper die being adapted to simultaneously press-form workpieces placed in press-forming stations. The lower die includes a base attached to the table, plural pairs of guide rails fixedly secured to a top surface of the base, each pair of guide rails having mutually opposing grooves, a plurality of first die segments for press-forming the workpieces into desired shapes, each of the die segments having a slider plate removably inserted into the grooves of each pair of guide rails, and a plurality of clamping units provided on opposite lateral sides of each pair of guide rails for clamping the slider plate against removal. The upper die has substantially the same structure as that of the lower die.

Abstract: To accommodate a press tooling carrier without interference, a control arm straight guide having at least one drive, e.g., having motor angular gears (worm gears), cardan shaft or the like is provided. A control arm straight guide permits a very shallow position of the joints in the completely assembled state. A hydraulic cylinder may be used to support startup of the motor, i.e., to move the control arm straight guide out of its bottom dead center position.
