Definitions

  • the invention relates to the technical sector of the production of parts in cast alloys and in particular in aluminum, magnesium, copper or other obtained in foundry, forging and similar processes.
  • EP 119 365 discloses a specific process called COBAPRESS which combines the techniques of foundry and forging of parts, in particular aluminum or aluminum alloy.
  • This process consists in casting aluminum or aluminum alloy in a mold, and after casting, in unmolding the still hot part at a temperature of the order of 400 to 500 ° C and placing it between two shells d '' a matrix defining an imprint of dimensions slightly smaller than that of the mold, the two shells being strongly pressed one against the other to exert, on the casting put between the shells, a combined effect of core pressing and wrought superficial.
  • COBAPRESS process is widely used for multiple applications for automotive parts such as connecting rods, triangles, pivots or suspension spindles, engine mounts and others, for cycle parts such as cranks.
  • the parts are cooled to room temperature.
  • a heat treatment can then follow at a temperature of 540 ° C. approximately for the soaking operation. It then returns to room temperature.
  • the aim sought after according to the invention was to optimize the process described in the aforementioned patent EP 119 365 in order to reduce the time necessary for the production of parts for all treatments combined, to eliminate the final operation of heat treatment by dipping.
  • the temperature homogenization time corresponding to the heating time for obtaining the same criteria for the part is in a variable duration depending on the desired mechanical characteristics of at least 30 minutes.
  • the oven used after the first casting of the part is a tunnel oven.
  • the heating time at 540 ° C. or substantially, and corresponding to the quenching temperature of the part dissolved, is within a range of 40 minutes to 2 hours and advantageously 1 hour.
  • the method thus described according to the invention makes it possible to eliminate the heat treatment and straightening operations initially necessary to avoid and correct the deformations of the part according to the prior art.
  • the intermediate treatment operation in the tunnel oven for a period of approximately 1 hour makes it possible to eliminate the operations which were carried out according to the previous technique downstream from the cast-forged operations and which took place during a period of 6 to 8 hours, and while obtaining characteristics substantially equal to those of the prior art.
  • the method according to the invention thus makes it possible to optimize the COBAPRESS method described in patent EP 119,365.
  • Another development of the invention consists in carrying out other operational phases if the performance of the invention is to be further refined.
  • the three casting operations, treatment in a tunnel oven at 540 °, then pressing are carried out as indicated above and are then extended by a fourth operating phase at the pressing outlet consisting in carrying out a complementary operation. re-solution of the part in another tunnel oven at 540 ° approximately for a period of 40 minutes to 2 hours and preferably 1 hour. This fourth operation is followed by a fifth soaking operation, then the parts obtained are cooled to room temperature. Parts in final operation undergo an income treatment.
  • This process allows the results to be refined and the parts treated to be homogenized.
  • FIG. 1 shows the different temperature stages.
  • the period x corresponds to the waiting time at room temperature of the part obtained according to patent EP 119 365 before the subsequent soaking operation.
  • the period y ( Figures 2 and 3) corresponds to the time taken for the solution to pass through the tunnel oven.
  • the improved method according to the invention in its two alternative embodiments makes it possible to substantially reduce the production time and the manufacturing cost by an approximate value of the order of 8 to 10% while obtaining the same characteristics of the parts compared to the COBAPRESS process described in EP 119 365.
