Definitions

  • the present invention relates to a device for producing a rotationally symmetrical gear part which has a hub, according to the preamble of claim 1.
  • Such a device is known for example from DE 4444 526 Cl.
  • the gear parts produced with such a device are used as function parts of various types. So they are used as sprockets, pulleys, especially as a poly-V pulley or the like.
  • serial parts in a rational manner, such as are used, for example, as transmission parts in motor vehicle construction.
  • the device has a tool pin, around which the hub is molded.
  • the material loosened from the surface of the round blank by means of the pressure roller flows by radially advancing the pressure roller along the tool pin a step-up, which forms an upper limit for the hub and whose distance from the round blank determines the height of the hub.
  • the diameter of the hub opening that is to say the center hole, is not less than a certain dimension, so that the usability of the corresponding gear part is somewhat restricted.
  • this also applies to the wall thickness of the hub to be formed, which is dependent on the diameter of the tool pin due to the deformation forces mentioned, so that a desired greater thickness of the wall thickness of the hub is only possible if the center hole has a correspondingly large diameter.
  • Gear parts with small center hole diameters and / or thicker hub walls can therefore often only be produced by machining, so that the advantages of the spinning process are not used here.
  • the present invention is therefore based on the object of further developing a device of the generic type in such a way that its usability is improved.
  • the support roller has the effect that, during the pressing of the round material towards the medium, the material prevents the material from flowing back towards the edge region or from building up of the material in the edge region.
  • the disk material moved by the spinning roller therefore flows exclusively towards the center, forming the hub.
  • the height of the hub is determined by the volume of the blank material displaced by the pressure roller, taking into account the desired wall thickness of the hub, i. that is, the thicker the wall thickness, the lower the hub height.
  • the support roller is preferably arranged in the area opposite the pressure roller and positioned so that its linear support on the round plate ends near the edge 3 of the abutment chuck which acts as an abutment.
  • FIG. 1 shows a device according to the invention in a schematic sectional view
  • Figure 2 shows the device in a plan view.
  • FIG. 1 is a device for non-cutting production with a hub
  • gear part which has at least one radially from the outside inward pressure roller 1, and a rotatable abutment chuck 2, in which a circular blank 4 lies.
  • the abutment chuck 2 is provided with an encircling, functioning as an abutment
  • a support roller 7 Opposing the pressure roller 1 there is a support roller 7, which rests under spring pressure in the outer edge of the round blank 4 and is held rotatably in a holder 8 transversely to the axis of rotation of the blank 4.
  • the diameter of the central opening or the hub bore 6 can be kept relatively small compared to the prior art.
  • the freely rotatable support roller 7 is arranged so that it rests with its linear contact on the round blank 4 close to the edge of the edge 3.
  • the support roller 7 can also be pressed onto the round blank 4 by means of hydraulics or pneumatics.

Abstract

L'invention concerne un dispositif servant à produire une pièce d'engrenage axialement symétrique présentant un moyeu (5) par un procédé de repoussage à partir d'un rond. Ce dispositif comprend au moins un rouleau de repoussage (1) pouvant être avancé radialement de l'extérieur vers l'intérieur, ainsi qu'une cale de butée (2) rotative présentant un bord (3) servant de butée. Ce dispositif se caractérise en ce qu'il comprend par ailleurs un rouleau d'appui (7) qui, en position de fonctionnement, s'appuie sur le bord extérieur du rond (4) et peut ainsi être mis en rotation perpendiculairement à l'axe de rotation dudit rond (4).
