Abstract

A progressive forming machine having a frame supporting a plurality of workstations uniformly spaced in a horizontal plane, a transfer mechanism for shifting parts from one station to another and from a last station to a discharge station, a conveyor in the frame for lowering parts from the transfer discharge station, the conveyor having individual part carriers, the conveyor being arranged to present a carrier beneath the discharge station in timed relation to the operating cycle of the machine.

Claims (8)

1. A progressive forming machine having a frame supporting a plurality of workstations uniformly spaced in a horizontal plane, a transfer mechanism including transfer fingers for gripping a part and for shifting parts from one station to another and from a last station to a discharge station, a conveyor in the frame for lowering parts from the transfer discharge station, the conveyor having individual part carriers, the conveyor being arranged to present a carrier directly vertically beneath the discharge station in timed relation to the operating cycle of the machine, whereby transfer fingers of the transfer mechanism directly drop a single part into an individual part carrier.

2. A conveyor for lowering formed parts in a progressive cold forming machine comprising an endless loop trained over top and bottom wheels and forming up and down stretches, a plurality of carriers uniformly spaced along the loop, the conveyor being adapted to dispose a carrier directly vertically beneath a part discharge station where a part is dropped from transfer fingers in the forging machine whereby the carrier can receive a part dropped directly from the transfer fingers at the discharge station, the conveyor having a plurality of carriers on each stretch of the loop whereby the conveyor can deliver a part to a level substantially below the discharge station at a low velocity rate in relation to the operating speed of the machine.

3. A conveyor as set forth in claim 2 , wherein said carriers are pivotally mounted on said loop and a mechanism is arranged to pivot said carriers from a downward discharge orientation to an upward carrying orientation while a respective pivot connection of the carrier is adjacent the top wheel, and a lower part supporting surface of a carrier remains below a top of the top wheel.

4. A conveyor as set forth in claim 3 , wherein the orientation of a carrier is controlled by the position of an associated carrier roller having a fixed relation to the carrier.

5. A conveyor as set forth in claim 3 , wherein said mechanism includes a channel that guides successive carrier rollers through a path to orient a carrier to the part carrying orientation from the downward orientation as a portion of the loop associated with the carrier pivot passes over the top wheel.

6. A conveyor as set forth in claim 4 , wherein two loops are provided and said carriers are disposed between said loops and are pivotally fixed to both loops.

7. A conveyor as set forth in claim 4 , wherein said channel pivots about a fixed horizontal pivot axis in timed relation to the rotation of one of said wheels.

8. A progressive forming machine as set forth in claim 1 , wherein the conveyor is defined in claim 2 .
