A die holder mounts a die to form heads on nails or screws. A top surface of the die includes a groove for longitudinally receiving and holding an elongate body. The die has a recess merging into the groove at one end of the groove to form a nail or screw head. The die is conical for press fit by contact with an inner surface of a bore or hole in the die holder. A top surface of the die is planar to a top surface of the die holder with a bottom surface engaging bottom part of the die holder. The bottom portion of the die has a recess or engaging with a corresponding protrusion die holder fixing an angular orientation of the groove relative to the die holder. Two opposite dies are brought together by two opposite die holders forming the head.

Some embodiments disclosed herein are directed to a tubular member including a central axis, a first end, a second end opposite the first end, an upset region between and axially spaced from the first end and the second end, and a first outer diameter axially spaced midway between the first end and the upset region. The upset region includes a second diameter which is larger than the first diameter, does not include a weld joint, and includes redistributed material from the tubular member.

A radial forge is provided with variable radial displacement. The forge includes upper and lower frames having upper and lower double acting hydraulically driven rams. The forge also includes a horizontal master gear mounted on a circular thrust bearing to provide rotational freedom. One or more radial hydraulically drive rams are mounted to the master gear. Accordingly, the master gear serves as a gantry for positioning the radial rams. A billet may be centrally located between the inwardly directed radial rams and may be supported by the lower ram. The upper ram is aligned with the lower ram so that actuating the upper ram and/or lower ram compresses the billet between them and forces the billet to flow into and fill radial dies removably affixed to the radial rams.

The present invention relates to tool, die, piece or mould, which, in use, is able to transfer heat out, in and/or through it, and where high mechanical and/or tribological loads have to be withstand at least in one area of the component. The invention also relates to several steel compositions with high fracture toughness and/or high resistance to decarburization comprised in the tool, die, piece or mould of the invention.

A forging apparatus includes an ironing mechanism and a phase alignment mechanism. The ironing mechanism includes: a punch set, which is fitted into a cylindrical portion of a pre-processing material to be formed into the outer joint member, and is radially expandable and contractible, the cylindrical portion having grooves formed in an inner peripheral surface thereof; and a die having a hole into which the cylindrical portion is press-fitted. The phase alignment mechanism is configured to align phases of the grooves in the inner peripheral surface of the pre-processing material and phases of track groove portion forming surfaces of the punch set with each other before the pre-processing material is fitted to the punch set.

A mounting plate for forming a gas turbine engine component according to an example of the present disclosure includes, among other things, a plate body defining an abutment dimensioned to mate with a forming die. The plate body defines at least one internal cooling circuit. The at least one internal cooling circuit includes a passageway having an intermediate portion interconnecting inlet and outlet portions. The intermediate portion is dimensioned to follow a perimeter of the abutment. The intermediate portion includes a plurality of fins extending partially from a first sidewall towards a second sidewall opposed to the first sidewall. A method of forming a gas turbine engine component is also disclosed.
