A method is used to forge an outer joint member of a constant velocity universal joint. Track grooves of the outer and inner joint members each have an arc-shaped ball raceway center line having a curvature center that is not offset in an axial direction with respect to a joint center. The forging method includes performing ironing by press-fitting a cylindrical portion of one end of a shaft portion of a pre-processing material of the outer joint member including the shaft portion and the cylindrical portion into a die hole of a die while a punch set that is radially expandable and contractable is fitted to an inner peripheral surface of the cylindrical portion. The punch set includes punches and a punch base to guide the punches to enable advancing and retreating. Each of the punches has a pair of forming surfaces for forming the adjacent track grooves.

A device for lightening the weight of vehicle components includes a tooling provided with a seat wherein the component is formed and a plurality of moveable bodies, which are moveable between an initial position and a final position, such that in the final position one end of each moveable body penetrates the seat of the tooling to form a cavity to lighten the weight of a component of the vehicle, wherein at least one of the moveable bodies can move laterally. Such device allows lightening the weight in a more simple and productive way than in currently known systems. This is achieved because the moveable bodies do not interfere with each other during the movement thereof, such that the lightening process can be done in a single blow during a forging procedure.

Modular forming tool (1), in particular pressing tool, preferably for producing essentially rotationally symmetrical parts, comprising at least one primary tool (10), in particular a core, at least one reinforcing tube (30) and at least one auxiliary tool (50), the forming tool (1) extending along a longitudinal extension direction (L), the primary tool (10) having a workpiece machining surface (12), a sheath surface (14) and two end surfaces (16), the workpiece machining surface (12) contacting or being designed to contact a workpiece, the sheath surface (14) delimiting the primary tool (10) in a radial direction (R), wherein the end surfaces (16) delimit the primary tool (10) in the longitudinal extension direction (L), wherein the reinforcing tube (30) has an inner sheath surface (32) and an outer sheath surface (34), wherein the primary tool (10) is pressed into the reinforcing tube (30) indirectly and/or directly via the sheath surface (14), so that the primary tool (10) is secured relative to the reinforcing tube (30) in the radial direction (R), wherein the inner sheath surface (32) and the outer sheath surface (34) each have an interference fit, wherein the auxiliary tool (50) is bounded in the longitudinal direction of extension (L) by cover surfaces (56), wherein the auxiliary tool (50) is bounded outwardly in the radial direction (R) by a circumferential surface (54), and wherein the circumferential surface (54) has a clearance fit in the radial direction (R).

Disclosed is a forming system having a first die assembly and a second die assembly with dies having die surfaces that are configured to cooperate with each other to form a die cavity therebetween so as to receive a workpiece therein. One or both of the dies includes a heater insert member that has a serpentine groove therein for receiving a flexible heater member. The flexible heater member is configured to conform with the shape of the serpentine groove. The heater insert member is position adjacent to the die surface and provides more uniform heating of the surface to form complex 3D surfaces with tailored properties.

A tool unit 20 and a press 21, particularly an embossing press. The tool unit 20 is simply and quickly arranged in or removed from a holder 23 of the press 21 in order to carry out a quick tool change with short downtime of press 21. For this purpose the tool unit 20 comprises a first tool 45 and a second tool 46 that are arranged along a tool axis A on a tool carrier 31. By means of a tool guide device 47, the second tool 46 is movably supported in a guided manner relative to the tool carrier 31 and the first tool 45, independent from guide devices of press 21. Therefore, the tool unit 20 can be prepared and set up during the ongoing operation of press 21. If desired or necessary, the prepared tool unit 20 is exchanged against the presently used tool unit 20.

A process for stamping metallic member with forging thickness of side walls, the process comprising: a forming step by forging, which forms the metallic member by forging; a step for forging thickness of the side walls, which extrudes the side walls of the metallic member to increase thickness of the metallic member; a specular treatment step with diamond cutter, which generates metallic texture of the side walls of the metallic member; and a finish step for forging thickness of the side walls of the metallic member. Wherein the metallic member, for example, is a sheet stamping component.
