Abstract

The invention relates to the technical field of an anode device for electroplating, in particular to an anode device for electroplating of an oil pipe inner wall. The anode device comprises an upper copper rod, a lower copper rod, copper connecting blocks, a copper cable and a titanium tube; a mounting ring groove is formed in the outer wall of the lower end of the upper copper rod, a mounting ring groove is formed in the outer wall of the upper end of the lower copper rod, and the mounting ring groove in the outer wall of the lower end of the upper copper rod and the inner wall of the upper end of the titanium tube are fixedly mounted together; the mounting ring groove in the outer wall of the upper end of the lower copper rod and the inner wall of the lower end of the titanium tube are fixedly mounted together; at least two copper connecting blocks are arranged in a cavity formed among the upper copper rod, the lower copper rod and the titanium tube at intervals, and the diameter of the copper connecting blocks is matched with the inner diameter of the titanium tube. The anode device is reasonable and compact in structure, the weight of the whole anode device can be effectively reduced, the device is not likely to be bent, meanwhile, the manufacturing difficulty and the manufacturing cost of the anode device can be effectively reduced, meanwhile, it is ensured that electric conduction is more uniform, and therefore electroplating quality is ensured, the yield is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of an anode device for electroplating, and relates to an anode device for electroplating the inner wall of an oil pipe. Background technique [0002] The uniformity of anode conductivity is a key factor affecting the quality of the electroplating layer. During electroplating, the plating metal or other insoluble materials are generally used as the anode, and the workpiece to be plated is used as the cathode, and the cations of the plating metal are reduced on the surface of the workpiece to be plated to form a coating. [0003] When electroplating the inner wall of the oil pipe with a length of 9 meters to 10 meters and a pipe diameter of 100 mm, insoluble materials are used as anodes for electroplating, and the conductivity uniformity of the anode device is a key factor affecting the quality of electroplating. When a titanium tube is used as the insoluble material of the anode, the conductivity of titanium...
