A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

A method of producing shaped parts includes drawing in the wire in cycles conveying the wire; severing wire portions in cycles; gripping and feeding the wire portion into work area; shaping the wire portion in multiple stages to form a shaped part with shank and head portions; ejecting formed shaped parts in cycles; transporting the fully formed shaped parts with a pneumatic conveyor system including a transporting pipe with an insertion opening: arranging the insertion opening near an ejector system such that the finished shaped parts can be inserted into the insertion opening directly in a positionally oriented manner by the ejector system; successively feeding the finished shaped parts into the transporting pipe by the ejector system; taking up the shaped parts inserted into the transporting pipe by suction into the transporting pipe; and pneumatically transporting the shaped parts through the transporting pipe in a direction of a subsequent station.

An iron-type golf club head with a cavity formed via a multi-stage forging process. The forged iron-type golf club head is formed from a single billet of material. An intermediate step of the multi-stage forging process creates a cavity in the iron-type golf club head which can receive an insert. The resultant iron-type golf club head has a substantially lower center of gravity and higher moment of inertia when compared to a traditionally forged iron-type golf club head lacking a cavity. Additionally, the resultant iron-type golf club head has a more solid feel than a traditionally cast iron-type golf club head as a result of the tighter grain structure the forging process yields.

The present invention provides a mold fixing structure capable of easily performing work in which a mold carried into a machine is fixed to a mold mounting surface of the machine, and work in which the mold fixed to the mold mounting surface is carried out to the outside of the machine.

The present invention provides a transfer device of a multistage forging press machine, capable of making a power transmission mechanism compact with a reduced number of components, and capable of easily adjusting a conveyance position. Additionally, the present invention provides a transfer device of a multistage forging press machine, capable of moving a plurality of chuck units in a lump to a place where replacement work can be performed easily, and capable of replacing chuck claws easily.

A forge and method of forging is provided. The forge converts an asymmetric railroad rail to a symmetric railroad rail through a combination of vertical and horizontal forging operations. The rail is linearly translated to heating and forging stations on a roller table. The asymmetric to symmetric conversion can be completed without the need for reorienting the rail except along a single translational axis.

A hydraulic forging press machine and a control method, whereby surging of the forging load or dead zones where the forging speed goes to zero is suppressed, and forging is performed with high precision throughout a wider range than the prior art, from low to high load. Pressure cylinders have a main pressure cylinder configured so working fluid is supplied during forging, and secondary pressure cylinders are configured so supplying and stopping of the supply of working fluid thereto are switched in response to the forging load, head-side hydraulic chambers of the secondary pressure cylinders being connected to a head-side hydraulic chamber of the main pressure cylinder via electromagnetic switching valves. Only the main pressure cylinder is used until the forging load exceeds a set load, and the number of secondary pressure cylinders used is sequentially increased as the forging load increases after the forging load exceeds the set load.

A progressive cold forming machine and a robot for automatically changing a cutoff cassette, tooling cassettes, a transfer slide and transfer cam. A loading area adjacent the machine and robot has provisions for supporting a tooling cassette pallet and a transfer slide and camshaft pallet and a holding area for temporarily receiving some of the componentry being exchanged.

The disclosure describes example systems and techniques for controlling microstructure of a superalloy substrate by controlling temperature during forging and using multiple die forging stages to formation of grain boundary phases of the superalloy, and components formed by such example systems and techniques. The method includes heating a substrate to within a forging temperature range. The substrate includes a nickel-based superalloy, and the forging temperature range is below an eta phase solvus temperature of the substrate. The method includes applying a plurality of die forging stages to the substrate to form a component preform. The method includes maintaining the substrate within the forging temperature range during application of the plurality of die forging stages and cooling the component preform.

A press comprising: at least one press ram by means of which a press stroke can be carried out when the press is actuated; at least one first working station and a second working station, wherein the first and the second working station each has a tool lower part and a tool upper part, wherein a first forming stage is formed by means of the tool lower part and the tool upper part of the first working station, and a second forming stage is formed by means of the tool lower part and the tool upper part of the second working station; and a mechanical element for transmitting the press stroke to one of the first or second forming stages, wherein the press stroke can be transmitted to the first and the second forming stages independently from one another.
