  • Patent number: 7401492
    Abstract: A control device (10) for a die cushion mechanism that produces a force for a slide (24) in a press machine, comprising slide velocity command-forming means (61) for forming a velocity command for the slide (24), die cushion velocity command-forming means (62) for forming a velocity command for said die cushion (20), and velocity relation calculation means (65) for calculating a velocity relation between the velocity of the slide and the velocity of the die cushion based on a rate of increase (dF) in the force produced between the slide and the die cushion immediately after the collision of the slide with the die cushion. The cushion velocity command-forming means forms the velocity command for the die cushion based upon the slide velocity command formed by the slide velocity command-forming means and upon the velocity relation calculated by the velocity relation-calculation means. This makes it possible to form an optimum velocity command for the slide and/or the die cushion.

  • Patent number: 7370507
    Abstract: Transfer apparatus and method are provided from first (15A, 16A) to second (15B, 16B) stations of tooling in a cap (11) making press. This cap is biased against the first upper tools by a first airstream (50) introduced under the cap and moves upward with the first station punch (45). As the punch approaches its top location, a transfer airstream (52) begins while the first airstream is still on, and moves the cap out through a transfer chute (18) to the second station. The cap departs the chute and passes detents (67) on a pair of closed retention fingers (60) which define an extension of the transfer path from the chute into the open second station tools. A vacuum (85) applied to a port in the second station punch then holds the cup against the rising upper tools. When the punch clears the closing fingers and approaches its top location, an ejection airstream (87) commences to propel the finished cup via a discharge chute (19).

  • Patent number: 7367893
    Abstract: An assembly line for continuously manufacturing fasteners from a rod with a groove for receiving a wire for retaining the fasteners in a strip includes a receiver for receiving the rod. A die press is arranged to receive the rod from the receiver and includes a piercing member for piercing an aperture in each fastener and a cutting member for cutting each fastener from the rod. A tapping member provides ribs to an inner wall of the aperture formed in the fastener by the piercing member. An inspector inspects the internal rib formed into the inner wall of the aperture disposed in the fastener verifying exactness of the aperture and the rib. A wire inserter inserts the wire into the groove forming a strip of connected fasteners. The inserter receives the fasteners sequentially from the inspector after verification of the exactness of the aperture disposed in each fastener.
