Definitions

  • the invention relates to a combination of a device and a preform for producing a light metal wheel from the preform and a method for producing a light metal wheel from a preform.
  • the invention relates to the production of light-alloy wheels, in particular made of aluminum or aluminum alloy by means of flow forming. This is a sub-form of Shear Forming, while in German different terms, such as flow (pressure) rollers, rotating rollers or draw rolls are used and here the latter term is to be used.
  • Stretching is a non-cutting forming process for final shaping of lightweight aluminum bodies such as aluminum or aluminum alloys, particularly metal wheels.
  • the preform of a wheel with a rotationally symmetrical sheath formation on a simple, rotating tool a mandrel is placed, which is rotated with the preform in rotation.
  • a plurality of differently shaped drafting rollers engage with radial pressure on the rotationally symmetrical peripheral wall of the Preform and are moved along this, ie in an axial component during the rotation of the preform, whereby on the one hand, a compaction of the material takes place, on the other hand, this stretched by the substantially axially extending draw rolls and thus deformed and just when producing a metal wheel for Rim of the same.
  • This processing operation in itself a cold-forming process, can be carried out at an elevated temperature of up to 350 ° C., wherein it should be noted that heating takes place anyway by the deformation process by means of the drafting rollers alone.
  • Such methods are basically from the US 2003/0145466 A1 or the ITVI20040061 A known.
  • the inner or underside of the wheel to be produced is predetermined by the shape of the mandrel and the peripheral edge of the rim flange can be optionally formed only in a complex manner by traversing the same with the drafting rollers, including the one hand complicated control operations of movement are required, on the other hand, the mandrel can disturb.
  • the EP 1 712 310 and the EP 1 714 714 A1 relate to the molding of a snap ring groove in the manufacture of oblique shoulder rims for trucks.
  • rims are usually processed in a flow-forming process.
  • a rim blank which is usually from a rounded to a hollow cylinder and butt welded sheet metal strip, so that steel, deformed by pressing of pressure rollers.
  • the workpiece is set in rotation about its longitudinal axis.
  • the molding is carried out by deforming a groove and then by means of a - attacking from the inside - element element substantially away from the longitudinal axis of forming the end portion of the workpiece to a - provided on the outside of the workpiece wall - a predetermined groove profile exhibiting counter element. So here it takes place only a reshaping of the metal strip in the region of the snap ring groove to be formed to this.
  • the DE 2 053 005 and the DE 2 231 842 relate to methods and apparatus for producing Schrägschulterfelgen itself (as they are then provided according to the aforementioned publications with a groove).
  • the flowforming process was not yet available.
  • the DE 103 22 752 A1 relates to a method for producing workpieces made of sheet metal with at least one branch by a forming process, among other things, rims for motor vehicles are addressed. But even here it is only about the pure forming to the effect that in the area of a previously introduced bending point by means of an attacking forming roller (2-2c) at least one weg josder from the sheet plane flange is formed from the sheet, with areas of this flange fastened differently, so compressed should be and thus have different strength in the final product. An axial stretching along the wall of the metal jacket does not take place here either.
  • the WO 2005/065049 A2 refers to the production of a one-piece steel wheel.
  • the process is multi-level and the individual stages are carried out in different form-changing processing stages.
  • a short cylinder jacket wall is radially perpendicular over a cylindrical mandrel by radially pressurizing and axially moving rollers.
  • a retracted into the interior of the cylinder barrel contoured other mandrel on this the shaping of the rim and its individual sections made by other rollers, which are also each in their working section (rim 3, tire seat 2 and 4) must move axially restricted.
  • the formation of the inner and outer rim flange (these two stages are preceded by further steps in turn other tools). It is essential that the rim flange is not formed by a roller in the first-mentioned stage of the stretching, but between only radially against each other engaging rollers / rollers is formed, although a non-working feed movement and the two rollers but only working radially against each oppressive.
  • the DE 1 452 610 relates to a method of forming an outwardly opening groove on a cylindrical tube.
  • the tube is stretched in a first step by means of a first roller along the cylindrical portion of a mandrel, which has a taper at one end.
  • a tailstock cushion and another roll To form the actual groove at the free end of the tube engage radially from the inside and from outside the taper of the mandrel, a tailstock cushion and another roll.
  • stretching and forming processes are separated and carried out by different tools.
