Definitions

  • the invention relates to a method for producing a pressed material commutator, which has the features of the preamble of claim 1.
  • a known method of this type (US-A-3 812 576) is disadvantageous primarily because of its relatively large number of individual operations which require transitions between several machines. In addition, this method can impair the secure bond between the segments and the molding compound.
  • the invention is therefore based on the object of specifying a method of the type mentioned at the outset which enables more economical production without impairing the quality of the commutator.
  • a process solves this task the features of claim 1.
  • the blank is preferably produced by extrusion, since then with this reshaping the flat part can be provided on its inside with radial grooves which are aligned with the grooves and merge into them. These radial grooves, along which the separating cuts are made to divide the segments in the flat part, reduce the required depth of these separating cuts, which not only reduces the effort for separating, but also makes a significant contribution to not endangering the secure anchoring of the segments in the pressed material.
  • the shaping by extrusion also enables the simultaneous molding of a ring of inner anchoring elements according to claim 3 without additional effort.
  • the inner anchoring elements are expediently separated from one another by the grooves extending to the edge of the central bore.
  • the grooves and preferably also the grooves are advantageously given a shape that widens in a wedge shape towards the free edge of the jacket. For one, there is such a form inexpensive for forming reasons. On the other hand, it is not difficult with such a shape of the grooves to seal them when the molding compound is subsequently introduced.
  • a circular blank is used as the starting material. This can be punched out of sheet metal or tape. However, the material consumption is lower if the round blank is formed from a disc cut from a bar material.
  • the inner anchoring elements are advantageously bent radially outward to increase their effectiveness. This bending process can be carried out in one operation by splitting off external anchoring elements from the inside of the jacket.
  • an annular disk is cut from a rod material. If the rod material is a thick-walled tube, the disc forms a round blank 1. If, however, the disc is cut from a solid material, a central hole 2 is then punched out to form the round blank 1.
  • the round blank 1 has a thickness of 4 mm with an outside diameter of slightly more than 20 mm.
  • the pot-shaped blank 3 shown in FIGS. 2 and 3 is formed by extrusion, which has an annular shape Plan part 4 and an adjoining tubular jacket 5 forms.
  • grooves 6 are formed on the inside of the jacket 5 in the axial direction and open towards the center, the number of which corresponds to the number of segments 7 of the commutator.
  • the grooves 6 are therefore evenly distributed over the circumference of the jacket 5.
  • the width of the grooves decreases evenly from the free end face of the jacket 5 towards the flat part 4.
  • the angle enclosed by the groove flanks is approximately 15 ° in the exemplary embodiment.
  • the grooves 6 are closed radially outwards by a material section 8 each.
  • the plan part 4 is also provided on its inside with radially extending grooves 9, one of which is aligned with each groove 6 and, as shown in particular in FIG.
  • the width of the grooves 9 therefore corresponds to the width of the grooves 6 at their end on the face part side. Since the segments 7 are separated from one another by separating cuts running along the grooves 9, the required depth of cut is considerably reduced by the grooves 9, to less than 2 mm in the exemplary embodiment. Since the groove 9 extends as far as the edge of the central hole 2, the groove 9 divides a collar formed on the inside of the plan part during the forming process and bordering the central hole 2 into a number of identically designed anchoring elements 10 corresponding to the number of segments 7.
  • a radially outwardly projecting ring flange 11 is molded onto the free end of the jacket 5 of the blank 3.
  • the material parts 8 are removed, as a result of which the segments 7 are separated from one another in the region of the jacket.
  • the sleeve displaces a material layer, the thickness of which is equal to or only slightly larger than the thickness of the material parts 8, in the axial direction towards the free end of the jacket 5, where in a tool receiving the blank 3 there is an annular space corresponding to the annular flange 11 to be formed, into which the displaced material flows.
  • the radial thickness of the material parts 8 is therefore chosen so that the volume of the displaced material layer is sufficient to form the ring flange 11.
  • the ring flange 11 can then be calibrated if necessary. This calibration can be carried out by means of the same press with which the extrusion of the round blank 1 and the formation of the ring flange 11 and the segmentation of the jacket 5 are carried out.
  • the connecting elements to be formed from the annular flange 11 and arranged centrally with respect to the segments 7 are now punched out.
  • outer anchoring elements 13 are also split off on the inside of the jacket 5 from the flange side.
  • the inner anchoring elements 10 are bent radially outwards to improve their anchoring effect.
  • the blank is filled with molding material 15, leaving a central hub bore 14 free.
  • the shape that receives the blank 3 is provided with ribs that penetrate slightly from the outside into the grooves 6 and close them tightly.
  • the required contact pressure of the flanks of the ribs against the flanks of the grooves 6 can be achieved thanks to the wedge-like tapering of the grooves 6 easily reach against the plan part 4.
  • the depth of penetration of the ribs is shown in Fig. 12.
  • the plan part 4 is segmented at the end by cuts running along the grooves 9, from the brush tread 4 '.
  • the slots formed by these cuts which, as shown in FIG. 10, also penetrate somewhat into the molding material 15, are denoted by 16.
  • the connection elements 12 are bent towards the brush tread 4 '.
  • the hub bore 14 is also unscrewed and the sprue of the hub body formed by the molding material 15 is removed by lowering.
  • the brush tread 4 ' can be turned.
