Definitions

  • the invention relates to a method for manufacturing outer parts of constant velocity joints of the kind set forth in the preamble of claim 1.
  • German Offenlegungsschrift 37 12 301 discloses a press tool for plastic deformation of a preform having a cavity open on one side to produce non-undercut axial ball tracks and cage guide surfaces.
  • the preform is received in an outer tool and the shaping of the wall regions is then performed by an inner tool with the application of pressure.
  • the inner tool consists of an inner die having individual radial ribs which reach through segments of a sleeve die to provide a forming surface which is closed in the circumferential direction.
  • the joint between the two parts of the inner tool is always in the transition between the ball track forming region and the cage guide surface forming region.
  • the part of the inner tool for making the ball tracks is formed by a one-piece solid tool part which can accept large forces without distortion or change in shape. This makes it possible to shape the ball track portions so precisely that no finishing operation is needed in these regions.
  • the intervening undercut cage guide surface regions are formed by the outwardly crowned segments of the sleeve die of the inner tool, the segments of which, after removal of the inner die, can be removed from the finished workpiece by springing them radially inwards.
  • the known press tool has the disadvantage that the two- piece inner tool is extremely complex and costly to manufacture and, owing to the parting surfaces formed between the two parts of the tool, namely the inner die and the sleeve die, has increased susceptibility to wear.
  • a further disadvantage is that the tolerances required for making the forming tool in two parts necessarily lead to an increase in the workpiece tolerances, that is to say, the current tool tolerances must be added to the specified workpiece tolerances.
  • German Offenlegungsschrift 42 14 444 discloses a method for the manufacture of ball sockets for constant velocity joints wherein a cup-shaped blank is progressively locally plastically deformed radially as a function of time, with plastic reduction in section, to shape its inner form against a profiled mandrel which in the circumferential direction is corrugated and which in the axial direction has different convex curvatures which vary, preferably segmentally, around the circumference.
  • the profiled mandrel used here is multipart and consists of radially separable profiled mandrel segments .
  • the object of the invention is to provide a method for the manufacture of outer parts of constant velocity joints of the kind referred to in which the disadvantages of the known manufacturing process which have been pointed out are avoided and in which ball tracks can be made either without or with undercuts .
  • the tool and process steps indicated in the characterising part of claim 1 are employed.
  • Fig. 1 shows a vertical section through the tool-preform arrangement at the start of the forming
  • Fig. 2 shows a vertical section through the tool-workpiece arrangement after the wobble forming
  • Fig. 3 is a bottom view of the one-piece inner tool.
  • the inner tool 1 is in the form of a one-piece wobble pressing die the outer contour of which has, by segments, different convex curvatures and includes rib-shaped contours 4 for the ball tracks and adjacent contours 5 for the cage guide surfaces.
  • the corresponding outer contours 4 and 5 are designed on the basis of a particular orbital angle in order to produce the desired final guide surfaces.
  • the preform 3 is received and fixed in an outer tool 2.
  • the outer tool 2 is moved upwards to the shaping die 1, which is still disposed centrally with respect to the machine axis, and then fixed.
  • the shaping die 1- is now set in wobbling movement.
  • An intermittent shaping force moves corresponding to the course of the movement - depending on the wobble frequency and the orbital angle ⁇ - circularly over the surfaces of the preform 3 which are being shaped.
  • the shaping die is rolled on the preform 3, i.e. between material and shaping tool 1 there is rolling sliding friction: this is considerably smaller than the frictional parameter in the conventional shaping process.
  • the yield stress of the material is only slightly exceeded by the maximum stress occurring, thereby ensuring a better flow of material.
  • the inner tool 1 is again disengaged centrally of the axis of the machine and the workpiece 3' can be ejected from the outer tool 2 by an ejector.
  • external splines 8 can be formed on the outer contour of the preform 3.
  • the outer splines 8 hold the preform 3 precisely in position and prevent it from twisting in the outer tool 2 under the influence of the wandering torque of the wobbling movement.
  • the external splines can be used as speed sensor for an ABS system.

Abstract

Cette invention concerne un procédé de fabrication de pièces femelles pour joints homocinétiques. L'opération s'effectue par déformation d'une préforme (3) ayant une cavité ouverte sur un côté pour réaliser des gorges à billes axiales sans dégagement de gorge (6) et des glissières de cage (7). La préforme (3) est portée par un outil externe (2) et l'outil interne (1) façonne plastiquement des sections de paroi interne pour les gorges à billes (6) et les glissières de cage (7), par application d'une pression. L'outil interne (1) comprend une matrice de pressage oscillante monobloc qui comporte des segments de différentes courbures convexes et qui, avant tout, est plongée centralement à l'intérieur de la cavité de la préforme, après quoi les contours définitifs souhaités des gorges à billes et des glissières de cage (7) sont réalisés par de multiples mouvements oscillants dans un angle orbital correspondant α.
