Definitions

  • Tools are known for the manufacture of metal parts by extrusion provided with lateral extensions such as the braces of universal joints. Such a device has been described in document FR A 2 226 228.
  • the present invention aims to allow the production of a tool for manufacturing by extrusion, preferably cold, of metal parts with opposite directions of spinning in the axis of the forging or parallel to it.
  • the die ensuring the spinning of an axial extension of the part which is opposite to another axial spinning, for example tubular, is placed in the movable part of the tool, said die being hooped dynamically during the movement.
  • This element can consist of a hoop of the fixed die (s).
  • the tools illustrated in fig. l firstly comprises a fixed part assigned to the general reference 1 and a tubular movable die 2.
  • the fixed part 1 is clamped on a table not shown. It comprises a base 3 supporting a punch 4 of generally cylindrical shape and the bottom of which has a frustoconical bearing 4a. This range is engaged in a bore of complementary shape 5a of a sole 5 placed above the base 3 so that the sole in question and the punch 4 are locked relative to each other.
  • Around the punch 4 is arranged an annular ring 6 resting on the 'sole 5.
  • the sole 5 and the base 3 are held externally by a centering ring 7 which also extends around part of a die 8.
  • a centering ring 7 which also extends around part of a die 8.
  • the periphery 8b of the matrix 8 is provided slightly tapered upwards.
  • This matrix is hooped in a hoop 9 with additional bore, clamped by any appropriate means with respect to the press table to ensure an energetic clamping of all the components of part 1 of the tooling.
  • the hoop being perfectly centered relative to the sole 5, perfect centering of the annular ring 6 is carried out relative to the punch 4.
  • the punch 4 and the annular ring 6 limit a spinning section intended for the construction of the axial skirt of a part, as will be explained better below.
  • the punch is provided with a head 4b whose end face is conical, while its periphery has a diameter slightly larger than that of the body of the punch.
  • the annular ring 6 has a flange interior 6a of diameter smaller than that of said ring.
  • the movable die 2 is in the form of a tube whose lower annular face 2a is frustoconical, the connection of this face and the internal bore 2b of the die comprising a bead 2c of diameter smaller than that of the bore 2b.
  • the action of the die 2 on the piece 10 generates two simultaneous actions: first the formation of a skirt 11 in the annular space between the ring 6 and the punch 4 (fig. 2) and then the production of a cylindrical shaft end 12 located opposite the skirt 11 and which forms inside the bore 2b of the die 2.
  • the outside diameter of the movable die 2 is at play almost equal to that of the bore 8a of the die 8, so that the introduction of the movable die 2 into said bore 8a causes its hooping dynamic from the moment the die comes into contact with the piece of land 10.
  • the punch 4 could have a complex shape allowing, for example, the production of a part 14 of the kind produced as indicated above, but the skirt 11 of which would be replaced by multiple axially oriented branches, for example for the production of the tripod fork of a universal joint.
  • FIG. 3 Illustrated in fig. 3 a tool capable of allowing the production of such a fork 14. It can be seen that the annular ring 6 has been eliminated, the bore 8a of the matrix 8 externally limiting the spinning of the branches 14a of the fork 14 including the axial rod 14b is spun inside the die 2. We observe the complex shape of the punch 4 which allows the branches and openings which separate them to be obtained.
  • the dynamic hooping system of the die 2 for the spinning of the rod 14b makes it possible to statically hoop the punch 4 with multiple dies intended for the spinning of the branches 14a.
  • the static hooping of the punch 4 makes it possible to ensure (despite its weakening form) optimum resistance to the force by making it possible to manufacture the part 14, which is not achievable by a conventional spinning process.
