Definitions

  • the present invention relates to a method for manufacturing parts from aluminum, or from a cast aluminum alloy, according to the preamble of claim 1.
  • One of the known methods consists in manufacturing them by stamping, or by forging, which has the advantage of giving them a metallographic structure at heart corresponding to high mechanical performance.
  • Another known method consists in manufacturing the parts by molding with lost wax, in particular when it is desired to produce parts having precise geometric dimensions, and a surface finish of an excellent finish.
  • the object of the present invention is to avoid these drawbacks, by using an improved casting process, making it possible to manufacture pieces of aluminum or light alloy having better performances than those obtained by a conventional process.
  • the method according to the invention consists in casting aluminum or an aluminum alloy, in a mold, to obtain a metal part as soon as the solidification is finished sufficiently rigid, and it is characterized in that immediately after the pouring, the still hot part is removed from the mold, and it is placed between two shells of a matrix defining an imprint of dimensions slightly smaller than those of the mold, the two shells of the matrix then being strongly pressed against each other, to exert on the casting, put between the shells, a combined effect of pressing to the core, and of surface dressing.
  • the core temperature of the molded part is still between 400 ° and 500 ° centigrade degrees at the time of pressing between the shells of the matrix.
  • the two shells of the matrix are mounted in a press, for example an eccentric press, which subjects the part to a percussion or to a pressing or a pressing between the two shells of the matrix.
  • the part is molded by tilting at ninety degrees, or one hundred and eighty degrees, in a shell, which makes it possible to obtain a quiet filling, without oxidation. , or bubbling.
  • An aluminum alloy is treated with copper, of the type known under the trade name AU5GT Y34.
  • a silicon aluminum alloy is used, of the type known under the trade name AS7G 06 Y33.

Claims (4)

1. Verfahren zum Giessen von Aluminium oder von legiertem Aluminium in eine Form um ein in genügendem Mass versteiftes Metallstück gleich nach Beendigung der Erstarrung zu erhalten, dadurch gekennzeichnet, dass das noch immer heisse Stück gleich nach dem Giessen aus der Form abgenommen und zwischen zwei Gusschalen einer Matrize eingelegt wird, die einen Abdruck beschreibt, dessen Abmessungen etwa kleiner als die Abmessungen der Form sind, wobei die zweie Gusschalen der Matrize dann stark gegeneinander zusammengepresst werden, um auf das Gusstück zwischen den Gusschalen eine kombinierte Wirkung von Herzpressen und oberflächlichem Schrecken auszuüben.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Herztemperatur des aus der Form abgenommenen Stücks zum Zeitpunkt des Pressens zwischen den Gusschalen der Matrize immer noch zwischen 400 und 500 Celsiusgraden liegt.
3. Verfahren nach einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass die zweie Gusschalen der Matrize in einer Presse montiert sind, mittels welcher das Gusstück zwischen den zweien Gusschalen der Matrize durch eine Schlag'wirkung oder eine Pressenwirkung beaufschlagt wird.
4. Verfahren nach einer der vorherigen Ansprüche, dadurch gekennzeichnet, dass die Formung des Gusstücks durch Verschwenken um 90 Grade oder um 180 Grade in einer Gusschale erfolgt, wobei eine ruhige Füllung, ohne Oxydierung noch Aufbrausen und entsprechend der Güte des herzustellenden Stücks erreicht wird.
