Definitions

  • the device further comprises means to move said clamp 15 (therefore the sheet 2) relative to said blade and counter blade 161 and 162, in successive steps, laterally with respect to the large dimension of the blade 162.
  • the clamp in its movement away from the blade and counter blade 161 and 162, the clamp does not will not stray too far from a plane perpendicular to the plane of the orifice 1, passing through the said orifice.
  • the frame 11 is pierced in the center of a window 101 extended on one side by a clearance 102, receiving press 16 (see Figure 2).
  • the counter blade 161 is mounted on a fixed blade holder 13, and the blade 162 is mounted on a movable blade holder 14, by means of trapezoidal keys 131 and 132 respectively (see more particularly Figure 4).
  • the back 130 of the fixed blade holder 13 is a circular base cylinder, i.e. forms an arc of a very large radius when viewed in the plane of FIG. 1, in order to be able to adjust the parallelism of the blade and counter blade 161 and 162 by moving the fixed blade holder 13 transversely relative to the frame 11.
  • a corner 181 is interposed between the movable blade holder 14 and a reference surface 17 on the frame 11, with interposition of needle roller tracks 185.
  • This corner 181 is mounted on a nut 183, itself mounted on a screw 180.
  • the translation of the screw 180 along its axis is blocked by suitable arrangement.
  • the translation of the movable blade holder 14 takes place while it remains always parallel to itself, the forces exerted by the mobile tool holder 14 in the direction parallel to the axis of the screw 180 are taken up by the frame 11.
  • the movable blade holder 14 and all of the members cooperating therewith are held in place against the frame 11 by a plate 160.
  • the cutting of the profile 32 will typically be different for each of the elements 31, according to the shape of the sculpture of the tread to be molded.
  • the invention lends itself perfectly well to computer-aided manufacturing. From computer files containing the definition of the sculpture, you can order a cutting cutting of preforms, for example a laser cutting machine. The invention allows therefore the production of molds of the type described in patent application EP 0 569 909 according to a very direct method.
