Problems solved by technology
However, the obvious defect of this method is that the welding scars are difficult to deal with, and the electroplating layer is partially damaged during the welding process, which directly affects the appearance and reliability of the product.
[0005] Some manufacturers use polished parts instead of electroplated parts to decorate cars, but the defects of polished parts are obvious. There is a color difference between them and the configuration of car exterior parts, and they are easy to change color, which cannot meet the needs of users.

Embodiment Construction
[0038] figure 2 A schematic diagram showing the structure of the auxiliary anode device used for double-cavity tailpipe electroplating according to the present invention. see figure 2 As shown, a hanger frame 20 is provided with several hooks 21 for placing the dual-chamber tailpipe. The rack frame 20 is generally composed of electrolytic copper plates, which serve as cathodes in electroplating. One embodiment of the auxiliary anode equipment used for double-cavity tailpipe electroplating of the present invention includes an auxiliary anode frame 22 connected and insulated with the hanger frame 20, and an upper auxiliary anode pair 23 and a lower auxiliary anode set on the auxiliary anode frame 22. The anode 24 is composed of three sets of inverted pin-shaped auxiliary anode groups. Auxiliary anode frame 22 can be connected with hanger frame 20 by electrical wire connecting buckle, and the green hook glue or hanger varnish used for electroplating between the two is used a...

Abstract
The present invention discloses a method for electroplating automotive dual-chamber tail pipe by utilizing auxiliary anode and its equipment. Said equipment mainly includes the following several main portions: hanger frame, auxiliary anode frame which is coupled with said hanger frame and insulated from it, auxiliary anode group including a pair of upper auxiliary anodes and a lower auxiliary anode and a tail pipe which can be mounted on the hanger frame. Besides, said invention also provides the concrete operation steps of its electroplating method.
Description
technical field [0001] The invention relates to an electroplating method for a double-cavity tailpipe of an automobile, in particular to an auxiliary anode device for electroplating a double-cavity tailpipe and a method for using the auxiliary anode device to electroplate the inner and outer cavities of the tailpipe. Background technique [0002] Automobile tailpipes are more and more widely used in cars at home and abroad. As a novel configuration, new styles emerge in an endless stream with the needs of automobile personalization and appearance aesthetics. A double-cavity tailpipe is born under this prospect. . [0003] figure 1 A schematic diagram of the structure of the double-cavity tailpipe 10 is shown, which includes a tailpipe body 11 and two bifurcated ends 13 and 14 of a U-shaped bifurcation, and the lower part of the tailpipe body is an installation head 12 . The double-cavity tailpipe 10 is installed on the rear of the automobile through the installation head 1...
