Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for electrolytic treatment of an aluminum alloy, which is used for electrolytic treatment of aluminum alloys, and particularly for anodizing treatment and electrolytic coloring treatment of heat-insulating profiles in which the profile members are connected by a heat insulating material. The present invention relates to a power supply jig for electrolytic treatment of a heat insulating profile.

2. Description of the Related Art A heat-insulating profile formed by connecting an outdoor-side profile and an indoor-side profile with a connecting member made of a heat-insulating material prevents heat transfer between the outdoor and the indoor-side profiles, and thus prevents a sash or the like. By applying it to building materials, it is possible to prevent dew condensation in winter and improve the efficiency of heating and cooling, so the demand for it is increasing.

The outdoor side and indoor side profiles used for such a heat insulating profile have conventionally been separately subjected to electrolytic coloring treatment before the two profiles are connected to each other. The heat insulating profile has been manufactured by connecting the outdoor side profile and the indoor side profile that have been electrolytically colored using the connecting member. Further, at the time of connection, the connecting member is fixed by caulking the peripheral portion of the connecting groove of the shape member with the end portion of the connecting member fitted in the connecting groove provided on both the shape members. I was trying to integrate and.

[0004]

However, in the conventional heat insulating profile, as described above, the outdoor side profile after the electrolytic treatment and the indoor side profile are connected to each other. Since the connecting member is fixed by crimping the connecting groove part of the shape, the oxide film that has been colored can be discolored, cracked, or peeled off in some cases due to plastic deformation during crimping. There is a possible problem. In addition, since the outdoor-side profile and the indoor-side profile that were separately electrolytically colored were combined, a subtle difference in color tone due to lots caused by slight differences in processing time and processing solution concentration caused the outdoor-side profile. It cannot be said that it does not occur between the indoor side profile and the indoor side profile, and in such a case the sense of unity as a heat insulating profile is impaired and the commercial value is reduced. It has been a problem of the conventional heat insulating profile to solve the above problem and prevent discoloration or peeling due to caulking, and to obtain a heat insulating profile having the same color tone of the outdoor side and the indoor side to have a unified feeling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in conventional heat-insulated profiles that have been subjected to electrolytic coloring treatment. Electrolysis is performed on heat-insulated profiles in the state where the profiles are connected by a connecting member in advance. It is possible to carry out the treatment, and at the same time, it is possible to supply power to both profiles connected by a connecting member made of a heat insulating material which is generally non-conductive, and to make the oxide film thickness uniform in the anodizing treatment. You can
An object of the present invention is to provide a method for electrolytically treating a heat-insulating profile and a power supply jig for electrolytic treatment, which can eliminate the color tone difference between the two profiles and improve the appearance quality of the heat-insulating profile in the electrolytic coloring treatment.

According to a fourth aspect of the present invention, the electrolytic treatment power supply jig is characterized in that a plurality of pressing members are provided so as to be movable along the power supply member.

[0009]

In the method for electrolytically treating a heat-insulating profile according to the present invention, notches are provided in each of a plurality of profiles constituting the heat-insulating profile, and these notches are hooked on the power feeding member made of a conductive material. By stopping it, the heat insulating profile is suspended in the electrolytic solution, and the power is supplied to a plurality of profiles at the same time via the power supply member that is engaged over both notches,
The difference in the oxide film thickness or the difference in color tone between the two profiles is eliminated, and the appearance quality of the heat insulating profile is improved. Further, since the heat-insulating profiles are subjected to the electrolytic treatment in a state where the profiles are connected to each other by the connecting member in advance, it is not necessary to perform the caulking process after coloring, and the problem due to the plastic deformation of the profiles is solved.

According to a second aspect of the present invention, there is provided a power feeding jig for electrolytic treatment of a heat insulating profile, which is suitable for carrying out the electrolytic treatment method of a heat insulating profile according to the present invention. A power feeding member for suspending a certain heat insulating shape member and a pressing member for pressing the heat insulating shape member suspended on the power feeding member are provided, and the power feeding member is formed on each of a plurality of shape members connected by a heat insulating connecting member. Since the pressing member presses the heat insulating profile from the back side of the notch, the heat insulating profile as the material to be processed falls off from the power feeding member. In addition, each of the plurality of shape members that make up the heat-insulating shape member will surely make conductive contact with the power supply member and be energized at the same time, forming an oxide film with an even thickness in the anodizing process. In the electrolytic coloring process So that the level difference is eliminated. Of course, since it is not necessary to perform caulking after coloring, problems such as discoloration due to plastic deformation of the profile and peeling of the oxide film can be solved.
