Abstract
A system and method of making a forged part. A flange may be forged between first and second ends of the part by actuating an upset punch against a second end of the tube that is disposed opposite the first end. The flange may extend away from an axis along which an upset punch is actuated.
Claims19
A method of making a forged part comprising:
- forging a workpiece configured as a non-tubular billet into a tube that extends along an axis and has a through hole;
- positioning the tube in a cavity of an upset die such that a first end of the tube engages an end surface of the upset die;
- and
- actuating an upset punch against a second end of the tube that is disposed opposite the first end to forge a flange between the first and second ends, wherein the flange is disposed opposite the through hole and extends away from the axis, the upset punch is disposed on a punch plate, the upset punch has a punch shaft portion that extends along an upset die assembly axis and has a punch end surface disposed at a distal end, the punch end surface is not disposed parallel to the axis and the upset die assembly axis, and the punch plate directly engages an upper surface of the upset die and the punch end surface directly engages the end surface of the upset die when the upset punch is actuated into the upset die to forge the flange.

A method of making a forged part comprising:
- forging a workpiece configured as a non-tubular billet into a tube that extends along an axis and has a through hole;
- positioning the tube in a cavity of an upset die such that a first end of the tube engages an end surface of the upset die that is disposed in a nonparallel relationship with the axis;
- and
- actuating an upset punch against a second end of the tube that is disposed opposite the first end to forge a flange between the first and second ends, wherein the flange is disposed opposite the through hole and extends away from the axis and wherein the upset punch has a punch shaft portion that has a punch end surface disposed at a distal end and a flange forming portion that extends around the punch shaft portion, and the flange forming portion is completely received in the upset die and the punch end surface directly engages the end surface of the upset die when the upset punch is actuated into the upset die to forge the flange.
