摘要： The problem of achieving great collar lengths with good quality and even when using high-strength metals, in particular high-strength steels, in a simple manner is solved by the disclosed methods and devices. One such method for producing a collar on a workpiece may involve preforming a region of the workpiece to form a material reserve for a collar drawing operation and drawing the workpiece to form a collar such that the drawn workpiece comprises a flange region and a drawn region adjoining the flange region, with the drawn region including a wall region and an adjoining drawn base. At least some material from a region of the material reserve may be used to form the wall region. The method may further involve punching the drawn base such that an opening is made in the drawn base and the wall region is adjoined by a drawn base sub-region, as well as widening the drawn base sub-region.

摘要： A method for producing rotationally symmetric structural components of metal, in particular steel, is provided. A blank is arranged in a torsion-proof manner on a first receptacle, the receptacle is rotated about a rotation axis so that the blank is caused to rotate about this rotation axis, at least one linear shaping element with a contour having at least partially an unrolled external contour of the rotationally symmetric structural component or a preform of the structural component is moved tangentially to the surface of the synchronously rotating blank, and the linear shaping element is at the same time pressed against the blank so that during the tangential movement the contour of the linear shaping element is formed at least partially into the blank. A kingpin or link pin of a connection link with a connection shaft and a link outer part is produced.

摘要： A machining tool, such as a forming, embossing, punching or pinching tool carries at least two tool elements at radial external faces for processing sheet metal. The tool elements are fixed to a tool body, either as separate pieces or integrated therein, and the tool body is rotatably supported in a receptacle. The tool body is rotatable about a rotation axis which is not perpendicular to the sheet metal during processing.

摘要： A multiple punch and multiple die assembly has a workpiece protector which is a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece.
