摘要： A method for the manufacture of a machine part with external teeth, particularly a starter ring or gear part, by spin forming of a circular blank and inductive heating which makes it possible to form high-quality tooth systems on an outer area of a cylindrical part. A circuit metal blank is fixed between chuck jaws in a spinning device and an end region is heated by at least one induction device and passes into a plastic state. Tools are then infed on either side of the chuck jaws and a forming operation, which includes material upsetting, is performed with a gear-cutting roll to form the external teeth. This is followed by induction heating of the teeth.

摘要： According to the present invention, in a heating step, an outer circumferential portion of a workpiece having a disk shape is heated to high temperatures. In a hot rough-rolling step, the outer circumferential portion of the heated workpiece is formed by use of a roller die to generate a rolled-gear having teeth. In a warm finish-rolling step, the teeth of the rolled-gear are finish-rolled by use of the finishing roller die. The starting temperature T.sub.1 of the hot rough-rolling step is set in the range of from 850.degree. through 1100.degree. C., the terminating temperature of the hot rough-rolling step T.sub.2 is set in the range of from 500.degree. through 700.degree. C. The starting temperature T.sub.3 of the warm finish-rolling step is set in the range of from 400.degree. through 700.degree. C., and the terminating temperature of the warm finish-rolling step T.sub.4 is set in the range of from 200.degree. through 650.degree. C.

摘要： For shaping longitudinal grooves or comparable longitudinal structures into round housings or housings which are otherwise regularly shaped with respect to a longitudinal axis, a press is provided with a deforming tool whose top tool presses a workpiece through a corresponding roll arrangement of a bottom tool. The bottom tool has an opening which is coaxial to the top tool contains an axially displaceable cage provided with a group of rolls. The rolls are rotatably disposed in the cage and are supported on radially exterior abutments which are stationarily held in the bottom tool. The rolls are constructed as profile rolls and shape the desired longitudinal structures into the workpiece when it is moved through between the profile rolls. The resulting radial reaction forces are absorbed exclusively by the abutments and not by the cage. For supporting the longitudinal movement of the cage, a transmission is formed, for example, by gear wheels which are rotatably disposed on the cage. The gear wheels are supported radially on the outside on stationary toothed racks and radially on the inside on a workpiece-operated slide provided with toothed racks.

摘要： In an impact rolling apparatus the axes of roller heads are arranged substantially perpendicularly relative to the longitudinal axis of the workpiece. Accordingly, a displacing of the material at the workpiece proceeds predominantly tangentially perpendicularly to the longitudinal axis of the workpiece, caused by the impact effect of the impact rollers mounted at the roller heads. By this arrangement of the roller heads impact rolling operations can be performed close to a shoulder of the workpiece and marked steps thus maintaining the advantages over the known impact rolling method at which the displacement of the material proceeds predominantly in the direction of the longitudinal axis of the workpiece.
摘要翻译：在冲击轧制设备中，辊头的轴线相对于工件的纵向轴线大致垂直地布置。因此，由安装在辊头上的冲击辊的冲击效应引起的材料在工件处的移位主要垂直于工件的纵向轴线切向。通过辊头的这种布置，可以靠近工件的肩部执行冲击滚动操作，并且标记的步骤因此保持了优于已知的冲击轧制方法的优点，其中材料的位移主要沿纵轴方向工件。

摘要： In a method for increasing the thickness of an outer peripheral portion of a metallic disc material, a first forming die is prepared so as to have a first groove portion on an outer periphery thereof for receiving the metallic disc material. The first groove portion has a pair of side walls and a bottom wall therebetween. The side walls has inclined surfaces facing each other so as to increase the width of the first groove portion toward the outer peripheral portion of the metallic disc material. One of the side walls has a greater length from the bottom wall of the first groove portion than that of the other side wall. The first cylindrical forming die is pressed against the outer peripheral portion of the metallic disc material in a radial direction to form a thickened outer peripheral portion of the metallic disc material. When the first forming die is pressed against the outer peripheral portion of the metallic disc material in the radial direction, the inclined surface of the one side wall of the first forming die is brought into contact with one surface of the outer peripheral portion of the metallic disc material, so that the outer peripheral portion of the metallic disc material is bent in a direction along the inclined surface of the one side wall while molding the thickened outer peripheral portion of the metallic disc material in the first groove portion.

摘要： An improved spline rack for use on a spline rack cutter is disclosed wherein the spline rack includes a plurality of teeth each having a top land surface that curves toward the inner tooth edge region, and the inner tooth edge region of each tooth includes a chamfer connecting the inner tooth edge region with the curved portion of the top land surface. In this manner, the exit radius of curvature of the inner top land surface may be maximized, while the chamfer prevents interference between the inner tooth edge region and the workpiece. A method of forming an improved spline rack is also disclosed.

摘要： A rotary forming machine assembly including a lower base (12) and a pair of spindle housings (14) including front (16) and rear (18) walls. The housings (14) are movably mounted on the base (12) for movement toward and away from one another. A tool spindle (20) is rotatably mounted between the front (16) and rear (18) walls of each of the housings (14) for rotation about spaced axes (B) to form a workpiece therebetween. The invention includes a deflection control bar (26) extending between and interconnecting the front walls (16) of the spindle housings (14). The control bar (26) limits the distance apart the (B) axes of the tool spindles (20) may move at the front walls (16) in response to the forming of a workpiece (22) between the tool spindles. The control bar is adjustably supported on the front walls (16) for selective movement in a direction parallel to a plane intersecting the axes (B). A dual thickness adjuster member (118 ) includes a rectangular thickness (148) slidably disposed within a rectangular groove (114) formed in the front walls (10) and a trapezoidal thickness (154) slidably disposed within a recess (112) formed in the control bar.
