Definitions
- the invention relates to the technical sector of the manufacture of parts in light alloy, in particular aluminum, obtained in foundry, forging and similar processes.
- EP 119.365 discloses a specific process called COBAPRESS which combines . foundry and forging techniques for aluminum or aluminum alloy parts.
- this process consists in casting aluminum or aluminum alloy in a mold and after casting, in demolding the still hot part called a preform at a temperature of the order of 400 ° C.
- COBAPRESS 2 therefore makes it possible to significantly reduce the production time and the manufacturing cost of the parts, while obtaining the same characteristics of the parts compared to the teaching of the COBAPRESS process described in patent EP 1 19,365.
- the spraying of the graphite solution on the forging die is an operation which, depending on the complexity of the shapes of the raw final part, is relatively long and costly, which does not systematically make it possible to have spraying homogeneity. in the parts of difficult access of the room, and finally which is very messy for the work station.
- US Pat. No. 4,683,742 which provides for the preheating of the billets before applying to them a coating of graphite type, then the billets being then forged after passing through a drying installation.
- the aim sought after according to the invention was therefore to ensure optimization of the initial COBAPRESS process of cast-forged light alloy.
- a first step was to focus on improving the conditions for depositing graphite in the forging matrix by spraying the graphite solution on the forging matrix, with better control of the distribution using robots.
- this solution is not very satisfactory, because it still requires human intervention, and the costs and environmental problems are still there.
- the process for manufacturing the light alloy parts is of the type implementing the following phases: - casting of the preform at a temperature of the order of 250 ° to
- the improved process for manufacturing light alloy parts is of the type implementing the following phases: - casting of preform at a temperature of the order of 250 ° to 500 ° C;
- FIG. 1 represents the diagram of implementation of the method according to the invention.
- the process for manufacturing light alloy parts according to the invention requires an installation with five successive specific zones covering the different stages of the process.
- the first zone (Zl) corresponds to the casting of the light alloy in a mold (1) allowing a preform (2) to be obtained under the temperature conditions mentioned above.
- the second zone (Z2) corresponds to the transfer of the heated preform (2) into a tank (3) for immersion and graphitation by coating the preform (2).
- the bath is a solution of graphite and water.
- a phase (Z3) of drying the preformed part outside the bath is provided.
- the following zone (Z4) corresponds to the transfer of the dried graphite preform into the tunnel oven (4) for temperature homogenization.
- the following zone (Z5) corresponds to the exit of the tunnel furnace of the preform to be then forged in a matrix (5) which is subject to less and faster lubrication limited to the bead bead according to the conditions mentioned above , then cooled to room temperature or accelerated or quenched.
- the black color resulting from the graphite bath makes it possible to better store calories and therefore to improve the structural and mechanical characteristics of the part; -
- a shade of color could meet a need for aesthetics and colors. Greater discretion for safety elements and more particularly suspension - chassis to avoid the shine effect under the body visible by the drivers next to the vehicle concerned.
