Definitions

  • the invention relates to a method of manufacturing a part. frustoconical annular such as for example a clutch rod, as well than a part obtained by this process.
  • This known method has the drawback of generating large metal scraps which considerably increases the cost manufacturing per piece.
  • the invention also relates to a part produced by the process defined above and comprising a radial weld zone.
  • a first step we cut from a wire metallic 1 of circular section unwound for example from a coil of wire not shown, a section 2 of predefined length.
  • the length of section 2 also depends on desired dimensions of the final part. In the concrete case mentioned above, we chose a length of section equal to 402.7mm.
  • Figure 2 shows in the disengaged position a first tool or a first press 7 of which only the upper 8 and lower 9 dies are represented. These matrices respectively define two surfaces planar, parallel annulars 8A, 9A between which are positioned so centered the blank 6.
  • the dimensions of a flat annular part 13 obtained from a section of wire 4.2mm in diameter and 402.7mm length are typically 119.5mm for the inside diameter, 137.5mm for the outside diameter and between 1.5 and 1.6mm with regard to its thickness.
  • the upper matrix 19 comprises on the one hand a housing cylindrical central 19A centering substantially complementary to the central part 20A of the lower die 20 and on the other hand a punch peripheral ring 19B intended to cooperate with the peripheral part 20B during forming.
