Definitions

  • the present invention relates to a device for producing a shaped body having a concentric hub according to the preamble of claim 1.
  • Shaped bodies produced by means of such devices are used in many fields of application.
  • the non-cutting production known as the spinning process, usually cold forming, is characterized by many advantages, which in particular allow rational and cost-effective production for series articles, such as those used as gear parts in automobile construction.
  • a generic device is such.
  • B known from WO 94/20235.
  • a molded body is produced from a metal blank, that is to say a sheet metal plate which has a central opening, and is provided with a concentric hub.
  • material is pressed out of the circular blank by radial infeed and pushed in the direction of the tool pin, where it is formed into a hub by molding onto this tool pin.
  • material displacement which can also be referred to as flow
  • the blank thickness is reduced in accordance with the material removal required for the hub formation.
  • the trailing roller serves firstly to prevent the round plate from bending open during pressing and secondly to precisely form the tool pin perform.
  • the trailing roller follows the spinning roller at a short distance.
  • the pressure rollers are designed so that their circumferential pressure surface runs parallel to the central longitudinal axis of the tool pin or the blank, the pressure surface directly adjoining the pressure edge which can be brought into engagement with the blank.
  • the material released from the round blank builds up in front of the pressure surface and is moved into the area of the tool pin, where it flows along it until it reaches a stop that specifies the height of the hub.
  • the material that has been swaged up, so to speak only flows parallel to or almost parallel to the tool pin immediately before it touches it, while previously taking up the space of a relatively thick bead.
  • the present invention is therefore based on the object of designing a device of the generic type in such a way that the loads which occur when pressing are reduced.
  • the pre-shaped hub is not pressed directly against the tool pin by the pressure roller. This is done by means of the trailing roller, the pressure surface of which runs parallel to the central longitudinal axis and with which the previously slightly inclined hub or the hitherto approximately funnel-shaped shape presses against the tool pin in such a way that a cylindrical shape results.
  • the trailing roller for the end limitation of the hub has a shoulder on which the free end face of the hub bears during molding.
  • the tool pin can also have a stop in the form of a shoulder, which limits the height of the hub and runs in the same plane, parallel to the round blank as the attachment of the pressure roller.
  • the width of the shoulder and the shoulder are preferably the same size, but together maximum according to the wall thickness of the hub.
  • the The hub is initially formed by the spinning roller in a funnel shape with an inclined wall in relation to the central axis of the tool pin and is then brought into a cylindrical shape by pressing the wall against the tool pin by means of the trailing roller.
  • the single figure shows a partial section through a device according to the invention in a schematic longitudinal section.
  • a device for producing a shaped body 1 having a concentric hub 12 which has a rotating tool plate 2 in the form of a chuck, a pressure roller 4, a follower roller 7 and a tool pin 3.
  • the tool plate 2 is provided with a recess in which a circular disc 11 lies, onto which the hub 12 can be formed by means of the pressure roller 4 and the follower roller 7, for which purpose the pressure roller 4 can be advanced axially and radially with respect to the central axis of the circular disc 11 ,
  • the initially disc-shaped, provided with a center hole round plate 11 is inserted into the tool plate 2 and set in rotation.
  • material of the circular blank 11, which initially projects beyond the tool plate 2 is pressed in the direction of the tool pin 3, the material so far separated being supported on a pressure surface 6 of the pressure roller 4.
  • This pressure surface 6 is inclined towards the outside relative to the longitudinal axis of the tool pin 3, starting from the blank 11, so that an initially approximately funnel-shaped hub is formed, as is shown on the right in the drawing.
  • the angle of inclination ⁇ of the pressure surface 6 is preferably 3-5 °.
  • the trailing roller 7 follows the spinning roller 4 immediately, whereby it is supported on the correspondingly machined surface of the round blank 11.
  • the trailing roller 7 also has a pressure surface 13, which, however, runs parallel to the central axis of the tool pin 3. Hence the initially inclined
  • Hub 12 pressed against the tool pin 3 and comes to rest there, so that a concentric cylindrical shape of the hub 12 is formed.
  • the trailing roller 7 On its side facing away from the round blank 11, the trailing roller 7 has a shoulder 8, which represents an end limitation in the design of the hub 12 and the latter
  • the tool pin 3 has a circumferential shoulder 9 which also forms a stop against which the hub 12 abuts.
  • the respective abutment surfaces of the shoulder 9 and the shoulder 8 are in one plane.
  • annular gap 10 is formed between the shoulder 8 and the tool pin 3, into which excess material can flow during the hub formation, so that an otherwise precise design of the hub 12 is possible without problems. This excess part can then be removed in a machining process.

Abstract

L'invention concerne un dispositif permettant de produire un corps moulé (1) pourvu d'un moyeu concentrique (12) à partir d'un flan (11). Ce dispositif comprend : un plateau outil rotatif (2) sur lequel repose le flan (11), un rouleur presseur (4) pouvant avancer axialement et/ou radialement, ainsi qu'un rouleur suiveur (7) conçu pour former le moyeu (12) autour d'une tige outil (3) disposée de manière concentrique. Le rouleau presseur (4) comporte, au niveau de la face orientée vers la tige outil (3), une surface de pression (6) à côté de laquelle se trouve la matière du flan enlevée par pression. Le dispositif selon l'invention est configuré de façon que la surface de pression (6) s'étende de manière inclinée par rapport à l'axe central de la tige outil (3), et plus précisément, vers l'extérieur à partir du flan (11).
