Definitions

  • the present invention relates to a forming press with elastic matrix.
  • the tool stamping machine has a male part and a part female between which is formed the part to be stamped.
  • the elastic matrix forming consists in simplifying the tool by reducing it to a single male or female part and to replace the other part with an elastic matrix. The main advantage comes from the savings made, since there is only half a tool left to manufacture for each different series of coins.
  • the elastic matrix is either a cushion elastomer, a bladder swollen with liquid.
  • the machine is dimensioned according to the pieces of dimensions maximum that it will have to train. Besides, the machine is also designed to withstand the maximum effort of forming which corresponds to the maximum forming pressure necessary applied to the larger room. Furthermore, the necessary forming pressure depends on several parameters: the material of the part, its thickness and forming radii.
  • Forming machines of this type have a frame, supporting the forming efforts, and including usually between a bottom beam and a beam upper, a jack, resting on the beam lower, and on the piston of which a pile of support rests, and on this heap of support a tool table for the removal different forming tools on which the sheets to be formed, and, bearing against the beam upper, a container inside which is located the elastic cushion acting as elastic matrix of forming acting in combination with a tool based on the tool table.
  • the pressure exerted by the forming matrix (the elastic cushion) is exerted over the entire surface of the table that enters the container.
  • the object of the present invention is to provide a more economical machine by limiting the effort of the machine, and therefore the resistance of its frame. This of course at a price of a compromise which means that, for large rooms, exerts only a lower forming pressure than that is necessary to obtain a part without retouching manual. So, for such parts, which do not represent that a small proportion of the whole production, we accepts manual retouching after the operation of machine forming.
  • the support pile is fitted with track rollers comprising means for place either in the retracted position in the support pile, or in the extended position.
  • said container is kept fixed to said frame by unlockable locks.
  • an elastic matrix forming press This comprises a frame 1 comprising a lower beam 2, an upper beam 3 and uprights 4 and 5 connecting beams.
  • a cylinder 6, comprising a piston 7, is supported against the lower beam 2.
  • the press includes a dismountable forming assembly allowing to exchange it against another.
  • This forming set includes a bunch support 8, a tool table 9, an elastic cushion 10 and its container 11.
  • the container 11 bears against the beam upper 3 and it is held in place by latches 12 and 13.
  • the support pile 8 rests on the piston 7 of the jack.
  • the tool table 9 rests on an annular cradle 14 which itself rests, on rollers 15, on rails 16 linked to the frame 1.
  • This arrangement makes it possible to release, by rotation, the tool table 9 of the machine in order to place a tool there forming such as 17 and sheet 18 to be formed, and removing the part once formed and also to replace tool 17 by another, in another form, if need be.
  • the support pile 8 is fitted with rollers retractable 19 mounted on cylinders 20 ( Figures 12A, 12B).
  • FIG. 12A a roller 19 can be seen in the retracted position in the support pile 8.
  • Figure 13 shows the detail of the support of a table tool holder 9 on its cradle 14 via a adapter ring 22 in the case where the tool table 9 'is smaller than the supports 23 of the cradle 14.
  • the support pile 8 has intended to cooperate, during the rise of the piston, with two conical holes 25 of table 9, so as to position them correctly the tool table on the support pile 8.
  • Figures 2 and 3 show a forming cycle of a room. After a forming tool 17 and a sheet 18 to form were dropped on table 9 as we see Figure 1, the pressure is sent to the cylinder, the piston 8 rises and presses the assembly 18, 17 into the elastic matrix 10 (figure 2) which applies the sheet 18 against the forming tool 17 by applying pressure substantially normal to the walls as if it were about near a liquid.
  • the piston is lowered, figure 3, until returning to the starting position where the table tool holder 9 rests on the cradle 14.
  • Figures 4 to 11 show a replacement cycle of one forming assembly by another in which the dimension of the tool table 9 is smaller, therefore also the section of the elastic cushion 10 and the section internal of container 11.
