Abstract

An apparatus includes an anvil having a first end and second end, and a press head reciprocally mounted relative to the anvil. The apparatus further includes an induction heater having a workpiece discharge end mounted adjacent the first end of the anvil, and a plurality of first station dies secured to the anvil. The first station dies each form at least a portion of a first contour. A plurality of second station dies are also secured to the anvil, the second station dies each defining at least a portion of a second contour.

First claim

The invention claimed is:

1. A method comprising:
heating a plurality of forgeable workpieces with at least one induction heater having a workpiece discharge end;
moving an arm of a die feeder into a first position adjacent the respective workpiece discharge ends such that workpieces exiting the workpiece discharge end are received by respective receptacles of the arm and are supported by trays;
moving the arm of the die feeder into a second position wherein the workpieces are unsupported by the trays and drop into a respective plurality of first station dies;
applying pressure simultaneously to the forgeable workpieces until the forgeable workpieces have a first shape; and
transferring each of the forgeable workpieces to one of a plurality of second forming stations having a second common die shape.

2. The method of claim 1 , further comprising:
upon depositing each of the forgeable workpieces in the second stations, applying pressure simultaneously to the forgeable workpieces until the forgeable workpieces have a second shape.

3. A method comprising:
inductively heating a plurality of forgeable workpieces with at least one induction heater having a workpiece discharge end;
receiving the forgeable workpieces from the workpiece discharge end at receptacles defined on an arm of a die feeder, the workpieces supported by trays;
moving the arm to a position where the workpieces are unsupported by the trays causing the respective workpieces to be deposited in one of a plurality of first forming stations having a first common die shape;
upon depositing the forgeable workpieces in the first stations, applying pressure simultaneously to the forgeable workpieces until the forgeable workpieces have a first shape;
transferring each of the forgeable workpieces to one of a plurality of second forming stations having a second common die shape; and
upon depositing each of the forgeable workpieces in the second stations, applying pressure simultaneously to the forgeable workpieces until the forgeable workpieces have a second shape.

4. The method of claim 3 further comprising:
measuring the temperature of each of the forgeable workpieces before the depositing of the forgeable workpieces.

5. The method of claim 3 , wherein the transferring of the forgeable workpieces to the second forming stations displaces each of the forgeable workpieces along a line parallel to a progression axis.

6. The method of claim 3 , wherein the first forming stations are positioned along a first line.

7. The method of claim 6 , wherein the second forming stations are positioned along a line parallel to the first line.
