Abstract: 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 reinfo

Abstract: A rolling tool (5) has a basic body (6) for fastening the rolling tool (5) in a rolling machine (1) and a profiled part (7) for the shaping treatment of a workpiece (2) to be rolled. The basic body (6) and the profiled part (7) are of multi-piece design. The basic body (6) and the profiled part (7), in their interconnected position, are mounted movably relative to one another in a plane perpendicular to the rolling direction (23). The basic body (6) of the rolling tool (5) can also be part of the rolling machine (1).

Abstract: A die module set (1) for a pressing tool for producing screws, threaded bolts and ball pins includes two different cores (5, 14) and two different reinforcement rings (8, 11) being designed to be coordinated in a way that a first die (2) including a first core (5) and the reinforcement rings (8, 11) or alternatively a second die (2) including the other core (14) and only one of the reinforcement rings (11) can be composed thereof.

Abstract: A method of manufacturing fastenings or fasteners with radial outer contours, especially screws or threaded bolts, made of solid metal is performed by a device. The method manufactures the fastenings or fasteners preferably on a multi-stage press. Several recesses running in an axial direction at a fixed radial distance are formed in the shank-shaped section of a blank. The prefabricated blank with the recesses is inserted into a multi-part split mold within a multi-stage press, whose die stocks have an inner profiling forming the outer contour, and are opened in the starting position, that at the places where the die stocks are opened, there are the recesses. During the closing movement of the die stocks, at least one radial outer contour is pressed on the shank-shaped section of the blank by radial action of forces, with the recesses preventing material from getting between the die stocks during the pressing process.

Abstract: A device and associated methodology for producing longitudinal components of metal with helical grooves, in particular spiral drill bits or screws, is provided. The method is suited for mass production and improves the cost effectiveness of production. The method includes providing at least one cold forming stage in which a blank is inserted in a guide mold and cold formed in a split mold with at least two movable jaws. The inner wall of the jaws includes at least one section with a contour designed as a negative of the helical grooves. By a heading tool which is movable in axial direction and which engages the free end of the blank positioned in the guide mold, the blank is pressed at least partially through the central opening of the closed split mold. Thus, helical grooves are produced during the contact with the mold contour by plastical cold forming.

Abstract: A method for the non-cutting production of an outer thread on hollow metal work pieces for use as hollow screws, hollow shafts, threaded sleeves or fittings as stable connecting or fastening elements. The method is particularly suited for thin-walled work pieces and a device is provided for carrying out the method. Within a multistage press formed with a displaceable carriage and a stationary work piece carrier unit, a wire or hollow tube section forming the base material is reshaped in one or more reshaping stages I to V into a finished hollow blank. In the multistage press, the pre-fabricated hollow blank is inserted in a further stage VI into a multipart split tool with a cavity having an inside wall that is provided with a negative of the thread to be formed.

Abstract: An economical, low-effort method and device for producing annular, rotationally symmetrical workpieces, rings or cores for dies of metal and/or ceramic powder or for pressing powder or massive forming of workpieces or components of metal with different qualities. A beam core or shaft-shaped element having at least one beam core is clamped into a rotatable clamping device and rotated. The beam core is made of temperature-resistant material and has at least one segment with an outer diameter corresponding to or smaller than the inner diameter of the workpieces. Metal and/or ceramic powder is fused onto the jacket surface of the beam core at a defined distance from the clamping fixture by a laser and applied in layers until a final wall thickness of the workpiece blank. After cooling, the beam core is partially or completely removed from the blank which is machined on inner and/or outer sides to final dimensions.
