Definitions

  • the present invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 8.
  • Cylindrical pot-like hollow bodies the lateral surface of which have a regular structure, such as in particular a toothing, are conventionally used, for example, by means of mechanical processes such as rollers or. Hammering or pressing.
  • Edge area of such hollow body necessary. This is usually done using separate, downstream processing machines.
  • a conventional method for the production of such ramparts provides that by means of a suitable tool in an additional work step in the axial direction of the
  • the object of the present invention was to find a method for producing such walls on the inside of tooth heads of a hollow body, which does not change the geometry of the outer contour of the tooth head, particularly in the area of the tooth flanks. According to the invention, this object is achieved by the features of the method according to claim 1.
  • the strength of the blow or Embossing process set such that a wall with the desired dimension, i.e. in particular the required radial expansion.
  • the wall is advantageously designed to extend over the entire width of the inner surface of the tooth head if the corresponding tool itself corresponds to this width, i.e. has a corresponding effective area.
  • Clutch disk carriers can of course also be used for other such cup-shaped hollow bodies.
  • FIG. 1 shows the view of a hollow body in the form of a clutch lamella carrier
  • FIG. 2 shows the longitudinal section through the clutch plate carrier according to FIG. 1;
  • FIG. 3 shows a detail of a front edge of a tooth head according to FIG. 2; 4 a) schematically the front view and longitudinal section of a tooth head of a hollow body according to FIG. 1 before the machining according to the invention;

  • FIG. 5 b schematically the front view and longitudinal section of FIG. 5 a) with the blow or. Embossing tool in the end position;
  • Fig. 6 is the view of another, preferably designed impact or Embossing tool.
  • FIG. 1 the view of a cylindrical hollow body in the form of a clutch plate carrier 1 is shown as it is used in automatic transmissions, for example for passenger cars.
  • Coupling lamellar carrier 1 has toothing profiles that run parallel to its longitudinal axis.
  • the bottom of the clutch plate carrier 1 is designed as an internally open flange 2, and while the toothing profile ends open towards the free end face, as can be clearly seen from the longitudinal section according to FIG.
  • Such clutch plate carrier 1 are conventionally by means of pressing, rolling or Impact method resp. combined process made from a blank directly in the profiled form.
  • the toothing profiles along the longitudinal axis thus also have an identical shape, and in particular the inner and outer surfaces of the tooth head and the tooth base run parallel to the longitudinal axis.
  • a radially inwardly directed wall 4 is now to be created on the inside 3 'of each tooth head 3, as can be clearly seen in FIG. 3 in the detail section of the longitudinal section according to FIG.
  • This wall 4 is intended to prevent the oil film formed on the inside of the clutch plate carrier 1 during operation from moving axially in the direction of the end face and thus leading to oil drainage in this direction. This means that the wall can only have very small radial dimensions,
  • this stamp 5 now has a width which is smaller than the width b of the tooth head 3. the embossing process is not carried out over the entire width b of the tooth head 3, but only over a partial area of this width b.
  • the inside of the tooth head 3 ' is inserted as required Wall 4 formed.
  • a small groove resp. Notch 6 formed on the outside. Due to the dimension of the stamp 5 according to the invention, the edge of the outer surface of the tooth head 3 is advantageously not machined or impaired, so that the tooth flanks 7 also still have the original shape after the stamping process.
  • the stamp 5 preferably has an at an acute angle to the outer surface 3 1 'of the tooth head 3 in
  • the width of the plunger 5 is preferably selected such that a wall is formed which spans the width of the inner surface of the tooth head 3 between the two inner tooth flanks.
  • Clutch plate carrier 1 or very wide tooth heads 3 can advantageously be a stamp 8 used as an embossing tool, which in addition to the actual embossing or.
  • the working surface 8 'and the holding surfaces 9 are advantageously made in one piece.
  • the work surface 8 'could also be made of a separate material and with the Base body of the holding surfaces can be detachably or firmly connected.
  • Such an embossing tool thus prevents lateral hiking or. Displacement of the material of the tooth head 3, and thus serves to maintain the shape of the outer shape of the tooth head 3 in question by the fact that these holding surfaces 9 act as counterholders to the punch 8 and only allow material to be moved within the tooth head 3 in the radial direction to the longitudinal axis of the clutch disc carrier 1.
  • Such a tool is particularly suitable, for example, with relatively thin wall thicknesses or wide tooth tips 3.
  • Embossing tool is shown schematically in longitudinal section of Figure 6.
  • the stamp 8 as an embossing tool and the holding surfaces 9 as a counter-holder 10 can be moved separately from one another.
  • the counter-holder 10 can first be brought into abutment against the tooth head 3 and only then can the stamp 8 be embossed against the top of the tooth head 3.
  • embossing processes for each individual tooth head 3 are advantageously carried out sequentially in sequence, ie the clutch disk carrier 1 rotates step by step about its longitudinal axis and the processing is carried out at one station.
  • two or more stamping operations to be carried out simultaneously in parallel with one another and for the clutch disc carrier to be rotated between the corresponding number of tooth heads 3.
  • the embossing tool is driven in a known manner, for example either mechanically or hydraulically. With a mechanical drive, a greater regularity and accuracy of the formation of the ramparts 4 is generally achieved.

Abstract

La présente invention concerne un procédé de production de saillies ou de bourrelets (4) faisant radialement saillie vers l'intérieur sur le côté intérieur (3') de sommets de dents (3) conçus de façon essentiellement axiale par rapport à l'axe longitudinal sur la surface d'enveloppe d'un corps creux essentiellement cylindrique (1), au niveau de l'arête frontale du corps creux (1). De tels corps creux (1) peuvent de préférence être des supports de lamelles d'embrayage destinés à être employés dans des transmissions automatiques. Des processus de frappe ou d'estampage sont de préférence réalisés radialement par l'extérieur contre l'axe du corps creux, sur le côté extérieur (3'') du sommet de dent (3), au niveau de l'arête frontale. Les processus de frappe ou d'estampage ne sont réalisés que sur une partie de la largeur (b) d'un sommet de dent respectif (3). Ainsi, il est possible d'éviter que lesdits processus de frappe ou d'estampage ne provoquent des modifications de la forme extérieure des sommets de dents (3), notamment des bords et flancs extérieurs (7).
