Description

TECHNICAL FIELD

[0001] The utility model relates to electroplating technical field, concretely relates to electroplating hanger for high-precision continuous seat valve cover. BACKGROUND

[0002] Electroplating is a process of plating a thin layer of other metal or alloy on the surface of certain metal by electrolysis, which is a technology of attaching a metal film to the surface of metal or other material parts by electrolysis to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.), and enhance aesthetics. Electroplating hanger is an important tool in electroplating production, mainly having the functions of conducting electricity, supporting and fixing the plated parts. The traditional hanger generally has a plurality of hanging teeth on the hanging rod, and the plated parts are directly hung on the hanging teeth. The hanger is connected with the electrode, so that the current is uniformly transmitted to the plated parts for electroplating.

[0003] However, there is a high-precision continuous seat valve cover 3 (as shown in the accompanying drawings Figure 7 and Figure 8 ), which is a square special-shaped structure, including a square base plate 310 and a pipe body 320 protruding from the front end face of the base plate 310. The four side corners of the base plate 310 form a sharp end area 301, and the corner area between the base plate 310 and the pipe body 320 forms a corner concave area 302. The four side corners of the base plate 310 are also hollowed out to form connecting holes 303. When the high-precision continuous seat valve cover 3 is placed on the ordinary hanger, the circumferential side of the high-precision continuous seat valve cover 3 is not blocked by other components. During the electroplating process, due to the electroplating sharp end discharge effect, the sharp end area 301 is located in the high area of the electroplating power line distribution, which causes the sharp end area 301 to easily burn; the corner concave area 302 is located in the low area of the electroplating power line distribution, which causes the plating layer of the corner concave area 302 to be insufficient and fogging, so that it cannot pass the salt spray test.

[0004] Therefore, how to design a suitable electroplating hanger for the high-precision continuous seat valve cover 3 and improve the electroplating yield has become the main problem to be solved at present. SUMMARY

[0005] In view of the above defects or deficiencies in the prior art, it is desirable to provide an electroplating hanger for a high-precision continuous seat valve cover. By providing a shielding part to shield the sharp end area, the shielding part is connected to the power supply cathode, so that during the electroplating process, the power lines converging to the sharp end area are dispersed by the shielding part, thereby avoiding burning of the sharp end area due to high potential; and the blocked power lines flow to the corner concave area through the avoidance opening formed between the shielding parts, so that the power lines distributed in the corner concave area increase, the thickness of the plating layer in the corner concave area increases, fogging is avoided, and the salt spray performance test of the high-precision continuous seat valve cover is qualified. The plating layer thickness of the high-precision continuous seat valve cover after electroplating is uniform, and the quality of electroplating is improved.

[0028] Please refer to the accompanying drawings Figures 1-8 The present embodiment provides an electroplating hanger for a high-precision seat valve cover, which includes a vertical main rod 1 and a plurality of hanging assemblies arranged along the length direction of the main rod 1. Each of the hanging assemblies includes two brackets 2 which are symmetrically arranged in an up-down manner.

The space surrounded by the shielding parts 210 on the two brackets 2 forms an avoidance opening 201. When the high-precision seat valve cover 3 is placed in the mounting area, the shielding part 210 is close to the tipped end area 301, and the avoidance opening 201 avoids and exposes the corned recessed area 302.
