Definitions

  • the invention relates to a method and an installation for shaping, by stamping, of parts made from a pre-cut strip material.
  • the present invention will find its application in the field of mechanics in general and, in particular, in that of building hardware.
  • a reel arranged at the start of installation, controls the unwinding of said strip, the latter being oriented, then, towards a cutting unit where it is cut into several sections of length determined according to the part to achieve. Then these precut strip sections are brought under a press and undergo one or more stamping operations.
  • the present invention proposes to remedy this problem posed by the supply of a press with a high production rate in parts from a strip material.
  • the invention as it is characterized in the claims, solves the problem consisting of a process of shaping by stamping of the parts from a pre-cut strip material, characterized in that: - a cutting device is supplied, by means of several strips, coming from separate coils, so as to constitute strip sections of length corresponding to the parts to be produced; - the different sections of precut strip are brought into a waiting position to constitute a buffer stock; - One takes one by one the strip sections thus stored and in the standby position to convey them, gradually, under the different machining stations of a stamping press.
  • the invention also relates to an installation allowing the implementation of this process, installation characterized in that it comprises: - first transfer means making it possible to bring one or more sections of precut strip from the cutting device into a waiting position at the entrance of a stamping press; - And second transfer means capable of removing one by one, said sections of strips in the standby position to convey them, progressively, under the different machining stations of said stamping press.
  • the present invention relates to a shaping process by stamping of parts from a pre-cut strip material. More precisely, said strip 1, in particular, of the metallic type, is stored, initially, in the form of a reel 2. This is disposed on a reel which rotates it, preferably, sequentially so as to cause the unwinding of the strip 1. The latter passes initially through a rectifier 3 so that, after cutting, the strip sections obtained are, substantially, rectilinear. Finally, the strip 1 is inserted into a threader 4 which engages it, according to a predetermined length corresponding to the length of the parts to be produced, in a cutting device 5.
  • the cutting device 5 is supplied via several strips 1, 1A from separate coils 2, 2A so that the rate of this supply can be considerably increased.
  • the invention solves the problem by ensuring a buffer stock 6 of these strip sections 15, 15A coming from the cutting device 5, between the latter and said stamping press 8. It suffices, then, to take, one by one, these strip sections 15, 15A from their standby position 9, 9A, 9B so as to gradually transfer them from one machining station 11, 11A, 11B to another under said stamping press 8.
  • the present invention also relates to an installation 14 allowing the implementation of the method as described above.
  • This installation is shown schematically in Figure 1 and in more detail in Figures 2 to 6 below.
  • the various strips 1, 1A initially supply a cutting device 5 so as to constitute sections of strips 15, 15A of length defined by the final part to be produced.
  • the first transfer means 16 are constituted, for example, by at least two arms 18 extending below the cutting device 5 and comprising, in their upper edge 19, housings 20, 20A capable of accommodating the different sections of strips 15, 15A cut simultaneously.
  • These arms 18 are, moreover, animated by a cyclic movement decomposing into a rise, so as to take, at the cutting device 5 said strip sections 15, 15A, this rise being followed by a horizontal displacement, then a descent to deposit, again, these strip sections 15, 15A in their waiting position 9, 9A.
  • These correspond, for example, to reservations 21, 21A, 21B arranged in a table 22 disposed at the front of the cutting device 5.
  • These arms 18 are then driven by a second horizontal movement so as to find their initial position below the following strip sections 15 ′, 15A ′ of the cutting device 5.
  • first transfer means 16 may also be constituted by a transfer belt comprising means for supporting the strip sections 15, 15A and having a sequential type advance movement.
  • the installation 14 further comprises second transfer means 23 capable of removing, one by one, the strip sections 15, 15A, 15B from their standby position 9, 9A, 9B so as to route them in the direction of the various machining stations 11, 11A to 11D under the stamping press 8.
  • these second transfer means 23 have the function of moving, step by step, both the sections of strips 15, 15A, 15B arranged in the standby position 9, 9A, 9B as those 15C, 15D, 15E, 15F, 15G already present at the various machining stations 11, 11A to 11D under the stamping press 8 from the inlet 17 of the latter to the outlet 24.
  • these second transfer means 23 come to take all of the strip sections 15, 15A to 15C to advance them with a pitch 34 so that the strip section 15G, initially disposed at the outlet 24 of the stamping press 8, is ejected of the installation 14 at a discharge ramp 33, while the sections 15B to 15F come to occupy the machining stations 11, 11A to 11D. They also ensure the transfer of the strip sections 15, 15A, from their standby position 9, 9A to their next standby position, respectively 9A, 9B.
  • a cycle of the second transfer means 23 allows only one standby position 9 to be released, and more precisely that located closest to the cutting device 5. From this done, an operating cycle of the first transfer means (16) generates a number of cycles of the second transfer means (23) equal to the number of strip sections (15, 15A) cut and conveyed, simultaneously by said first transfer means (16).
  • this particular arrangement of the present invention makes it possible to prevent the rate of supply of the stamping press 8 from limiting the rate of production of the latter.
  • These second transfer means 23 can take an identical configuration to the first transfer means 16 described above.
  • they consist, according to a first embodiment of at least two arms 25 extending below all of the strip sections 15, 15A to 15G arranged both on the table 22 and under the stamping press 8.
  • These arms 25 comprise in their upper edge 26 housings 27, 27A to 27C equal in number to said strip sections 15, 15A to 15G so that they are able to move all of them by one step 34 during a cycle.
  • this cycle of the second transfer means 23 is controlled by the stamping press 8 so that the rise, followed by the displacement of a step 34 of the different strip sections and the descent of the arms 25 takes place during the phases of ascent and descent of said stamping press 8.
  • these second transfer means 23 are constituted by clamps in number equivalent to the different strip sections 15, 15A, 15B in the standby position and to the strip sections 15C to 15G arranged under the machining stations 11, 11A to 11D. These clamps evolve, under these conditions, in a cyclic movement so as to advance by one step 34 the different strip sections 15, 15A to 15G at each drawing cycle.
  • clamps can be replaced with suction cups or any other gripping element capable of moving the strip sections under the conditions set out above.
  • both the first transfer means 16 and the second transfer means 23 can be actuated by means of conventional control means 28.
  • cam shafts 29, 30 arranged below the cutting device 5 and the table 22. These cam shafts 29, 30 confer the cyclic movement and at the desired rate, to the arms 18 of the first transfer means 16 or to the arms 25 of the second transfer means 23.
  • a motor 31 ensures the drive of said cam shafts 29, 30 through a system of gear 32 allowing the speed of rotation to be varied.
  • the operation of the different transfer means 16, 23 is dependent on the frequency of the stamping cycles, on the one hand, and on the different phases of these cycles on the other hand.
  • the operation of said transfer means 16, 23 can advantageously be managed by means of a programmable electronic processing unit. Note that this makes it possible to drive the camshafts 29, 30 by means of separate motors. The operation of the latter is then managed by said programmable processing unit so as to adjust it to the speed of the press or vice versa.
  • Such an arrangement in fact authorizes individual control of the different transfer means 16, 23 and, ultimately, better adjustment of the installation.
  • the present invention makes it possible to solve the problem by authorizing the multiplication of the supply of a press to stamp by means of several bands.
  • This stamping press can thus operate according to a maximum production yield, which ultimately results in a lower production cost.
