摘要： An apparatus and a method for producing a one-part vehicle wheel are provided, in which a substantially disk-shaped, undercut-free preform is cast. Immediately after casting the preform is conveyed to a flow-forming machine, whilst maintaining a residual heat and is fixed therein. The circumferential area of the fixed preform is split and by subsequent spinning and flow-forming is constructed as an intermediate form with a rim, which already substantially has the wall thickness of the rim of the finished vehicle wheel. The intermediate form is cooled, sized and undergoes a final end-working.

摘要： A method for the manufacture of a machine part with external toothing from a circular sheet metal blank. According to this method the blank is fixed between a tool and a tail stock. Subsequently the circumferential edge of the circular sheet metal blank is bent by a first metal working roll towards the side of the tool by an angle of more than 180.degree. to form a curl. This curl is radially flattened with a second metal working roll. Subsequently the flattened curl is pressed against the tool with a gear cutting roll and shaped to form an external tooth system.

摘要： The invention relates to a method for the manufacture of a vehicle wheel with a wheel body and a rim having at least one undercut. In order to provide a simple, inexpensive method for the manufacture of a weight-reduced vehicle wheel, according to the invention the construction of an undercut in the rim area is integrated into the manufacture thereof by a spinning process. A cast preform having a clearly defined construction, is fixed in a spinning machine where initial preshaping takes place, a rim bed with an inside rim horn is formed and then by splitting and forming a rectangular flange cast radially onto the wheel body, the undercut and an outside rim horn are constructed. Following a heat treatment, machining is carried out for the final rim construction.

摘要： The invention relates to a method for forming a hub disk, in which a circular blank-like workpiece is placed in a flow-forming machine and fixed with at least one overarm support, an area of the outer contour of the overarm support corresponding to an area of the inner contour of a hub to be formed, the circular blank-like workpiece is rotated, at least one roller is infed and substantially radially moved in, a material flow taking place on the workpiece, and the radial moving in of the roller is ended when the distance between an area of the outer profile of the roller and the overarm support corresponds to the desired thickness of the hub wall and during the infeeding of the roller the workpiece is initially contacted by a cutting or separating edge of the roller and the material flow along the roller and therefore the axial length of the hub is limited by the roller geometry. The invention also relates to a roller for use in forming a hub disk, the outer circumference of the roller having a cutting edge, with which it initially contacts a workpiece to be formed, and a circumferentially positioned projection spaced from the cutting edge is provided for limiting the axial material flow.

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： A method of manufacture of a gear part with a bottom area and a circumferential area, which has two portions. One portion extends to one side of the bottom area, while the other portion extends to the opposite side of the bottom area. On one portion is formed an inner profiling and on the other portion an outer profiling. According to a first method, on a cup-shaped preform a web is formed by splitting or flow-forming and extends in the opposite direction to the cup wall. In the thus formed web and in the cup wall are subsequently made the desired profilings. In a second method, an arcuate curl is produced and is subsquently flow-formed to the portions with the profilings.

摘要： The invention relates to a method and an apparatus for the manufacture of a poly-V-pulley, particularly with a toothed reference mark sensor. The method uses per se known spin forming and combines in one setting on a spinning machine with tool changers, the method steps of upsetting, profiling and gear cutting. The method according to the invention is preferably based on a tilted circular metal blank, which has a bevelled or angled marginal area with a clearly defined length and wall thickness. From the tilted or upset blank is formed a cup-shaped preform with an asymmetrically reinforced, cylindrical area with the aid of a spinning roll and subsequently in a radial setting is infed a spinning roll with a recess and an axially limited diameter reduction and material accumulation are obtained. This is followed by preprofiling, profiling of the thickened area and a gear cutting on a simultaneously constructed reference mark sensor of an outer flange.

摘要： The invention relates to a method for the manufacture of a rotationally symmetrical part, particularly a vehicle wheel. The starting material is constituted by a circular blank preform, which has a substantially radial base and a connecting, axial shoulder. The shoulder is firstly rolled out by spinning rollers axially on either side of the base to a first web and a second web. At least one of the two webs is spun against a spinning chuck. Subsequently the outer contour of the webs is finally shaped and calibrated in the outer regions.
