Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating, and in particular relates to an end fixing tool for workpiece electroplating. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics. The outer layer of many coins is also electroplated.

[0003] After searching, the patent with application number 202223165064.6 discloses a fixing tool for mold electroplating. The patent sets up a cylinder, a trapezoidal block and a wedge block, and uses the cylinder to push the trapezoidal block up and down. The movement of the trapezoidal block drives the wedge blocks on both sides to be relatively close or away from each other, thereby achieving the clamping and fixing of the mold and improving the stability of the work. Although it avoids the trouble of manually taking and placing the workpiece in the electroplating solution, the continuous contact between the clamp and the workpiece will make the contact part not be electroplated, thereby reducing the electroplating effect.
