Abstract
The invention concerns a method of producing aluminium housings, in which formed components of the housing are subjected to heat treatment, affixed with adhesive and given a finished coating of resin. The invention proposes the selection of materials, adhesives and resins which enable final assembly of the housing (including finish coating) to be carried out using a single heat treatment.
Description
SPECIFICATION
Method of producing aluminium housings
The invention concerns a method of producing aluminium housings, in which at least one component part of the housing is formed from an aluminium alloy and is to be subjected to heat treatment for a defined period within a predetermined temperature range, and in which at least one housing seam is fixed by means of a hardened metal adhesive, and in which at least one part of the housing is coated with a resin.
Methods of this kind are not new. Normally
Al-Mg-Si alloys are used in which an increase in rigidity occurs after they have been exposed to heat for a defined period of heat treatment within a temperature range of 150 - 180"C. After heat treatment the formed and hardened components are assembled into a housing, whereby instead of welded joints or screwed joints a metal adhesive is often used. Until the metal adhesive has hardened, the metal seams are pressed together by means of suitable clamps. Next the surface finish is applied by application of a synthetic resin coating which is hardened/stoved at an increased temperature. The final product is then complete.
It is clear that the present method of production of such aluminium housings makes demands on time and space for the intermediate storage of semifinished products. The aim of the invention is to eliminate these disadvantages.
According to the invention in a method of producing aluminium housings in which at least one component part is formed from an aluminium alloy and is to be subjected to heat treatment for a defined period within a predetermined temperature range, in which at least one seam of the housing is fixed by means of a hardened metal adhesive, and in which at least one part of the housing is coated with a resin; the metal adhesive and the resin are selected so as to harden under the same heat treatment as is required for the aluminium alloy, and, wherein after the component parts of the housing are formed, final assembly of the housing is carried out with simultaneous application of the metal adhesive and mechanical fixing of the seams of the housing, the resin coating is applied to the housing, and then the finished product is subjected to heat treatment to harden the metal, the metal adhesive and the resin coating at the same time.
Preferably the seams of the housing are fixed by means of clamps fitted within the outer periphery of the housing, the clamps exerting a compression force on the metal parts forming the seams.
One particularly advantageous version of the method proposed by the invention is the use of clamps within the interior of the housing or set within the thickness of the walls to fix the housing seams mechanically and to exert a compression force on the metal parts which form the housing seams.
The method of the invention makes it possible to produce aluminium housings using only one heat treatment, thus saving a considerable amount of time.
Another particular advantage is the fact that in accordance with this invention the finished product with its final surface finish can be manufactured continuously, i.e. without any intermediate storage.
The single heat treatment fulfils several functions at once. On the one hand the bending stresses resulting from the process of forming the component parts of the housing are reduced and the aluminium alloy is strengthened by hot storage. On the other hand the metal adhesive is also hardened and at the same time the finish coating hardened stoved.
Normal clamping arrangements can also be used to fix the housing seams with the method of the invention. The aforementioned clamps are however more suitable, these being, for example, tapped into grooves or holes provided for this purpose in the thickness of the walls of the adjacent metal parts, thus not only fixing the housing seams but also exerting a compression force upon the metal parts which form the housing seams. This enables final assembly of the housing to be carried out prior to the subsequent heat treatment and without the use of external clamping arrangements, thus making the method of the invention even more advantageous.
1. In a method of producing aluminium housings in which at least one component part is formed from an aluminium alloy and is to be subjected to heat treatment for a defined period within a predetermined temperature range, in which at least one seam of the housing is fixed by means of a hardened metal adhesive, and in which at least one part of the housing is coated with a resin; the metal adhesive and the resin are selected so as to harden under the same heat treatment as is required for the aluminium alloy, and, wherein after the component parts of the housing are formed, final assembly of the housing is carried out with simultaneous application of the metal adhesive and mechanical fixing of the seams of the housing, the resin coating is applied to the housing, and then the finished product is subjected to heat treatment to harden the metal, the metal adhesive and the resin coating at the same time.
2. The method according to claim 1 wherein the seams of the housing are fixed by means of clamps fitted within the outer periphery of the housing, the clamps exerting a compression force on the metal parts forming the seams.
