Abstract

The invention provides a cathode structure, an electrochemical polishing tank and electrochemical polishing equipment. The cathode structure comprises at least one first cathode part and at least onesecond cathode part, wherein the first cathode part is connected with the second cathode part; and the first cathode part and the second cathode part are used for polishing the surfaces of workpieces.The electrochemical polishing tank comprises the cathode structure; and the electrochemical polishing equipment comprises the electrochemical polishing tank. Through the cathode structure, the innersurfaces and the outer surfaces of the workpieces can achieve good polishing effects, so that the appearance quality of the inner surfaces and the outer surfaces of the workpieces can be improved. Inaddition, compared with the traditional cathode structure which is a single structure, the cathode structure is a combined structure and is capable of finely adjusting the spacing between the workpieces and the cathode structure, so that the workpieces with complex structures achieve better polishing effects.

Description

technical field [0001] The invention relates to the technical field of electrochemical polishing, in particular to a cathode structure, an electrochemical polishing tank and electrochemical polishing equipment. Background technique [0002] Medical metal stents can be made of stainless steel, titanium alloys, nickel-titanium alloys, cobalt-chromium alloys and other metals, and are prepared by laser cutting or weaving. Medical metal stents are mainly used in the tissue cavity or blood vessel cavity in the body to treat various diseases of the tissue cavity or blood vessel cavity. After the pre-processing of medical metal stents, there will generally be residual slag, burrs, and oxide films on the surface. The metal stents must be pretreated first. Pretreatment includes operations such as grinding or pickling. Electrochemical polishing can improve the biocompatibility and corrosion resistance of metal stents, and improve the application performance of metal stents. [0003] ...
