Definitions

  • the invention relates to the technical sector of the parts obtained by casting operations of foundry, forging and also parts undergoing two successive operations casting foundry and forging.
  • this method consists of producing a preform in the foundry casting of aluminum or aluminum alloy parts and then transferring it to a forge die whose imprint is substantially smaller in size than the dimensions of the preform and exerting a striking operation to obtain a part with the shapes and dimensions chosen with superior mechanical characteristics.
  • the foundry casting preform is immersed in a bath containing a graphite coating and then transferred into a tunnel oven at a temperature of the order of 400 to 500 °.
  • This Transfer operation in the tunnel furnace is intended to make particularly malleable the preform for the next forging operation.
  • the forge matrix also has a prior emulsion type poteyage to facilitate the creep of the material in the area of the burr and prevent the alloy from adhering to the tools.
  • foundry poteyage is the action of depositing a protective coating to facilitate the release of the part.
  • This practice is known for sand casting, metal casting, gravitational casting.
  • the poteyage can be permanent (ex casting metal mold) or applied between each casting.
  • the poteyage is done through nozzles or brushes.
  • Foundry is also known in the foundry to oil by manifold or robot and also the dry poteyage in the particular case of the foundry under pressure.
  • the invention consists in implementing in a casting process a preform in shapes of desired dimensions, to transfer said foundry preform in a tunnel oven and then a preheating operation at a temperature of the order of 500 °, to transfer the preheated foundry preform in a forge matrix to dimensions and substantially less shape and perform the striking operation at a pressure of the order of 600 to 700 MPa, the method being characterized in that prior to transferring the preheated foundry preform into the forging die, said forging die and pin-shaped preform positioning means are subjected to a powder-spraying operation over the entire surface inside of the forge die capable of receiving the preheated foundry preform and on the pins.
  • the spraying can be done with or without electrostatic deposition.
  • the electrostatic deposition ensures homogeneous deposition and makes it possible to reach inaccessible areas on the forge die with respect to the configuration of the preform.
  • the powder which is sprayed and sprayed contains a wax as a carrier for the release agents and melts at 100 ° C.
  • the powder may include a composition based on graphite particles or not in very limited proportions in the case of electrostatic deposition of the order of 10% maximum.
  • the solution provided by the invention has many advantages over the technology developed by the Applicant. It is no longer necessary to have a retention tray graphited coating and there is more water to use. There is no longer a need to monitor the dilution ratio which significantly reduces the cost of monitoring and maintenance. The noise made for the projection of the liquid potting on the matrix is reduced to the environmental level, as for the suppression of the coating tanks, there is no longer any liquid discharge and there is no fouling of the network. Aspiration related to the projection of liquid potting on the matrix.
