Description

Technical Field

[0001] The utility model relates to metal-based grinding wheel production equipment, in particular to an electrode assembly used for abrasive plating of metal-based grinding wheels. Background Art

[0002] Patent document CN202187072U discloses an electrode for electroplating, which includes an electrode rod body, the electrode rod body has a flat-topped cone, the base of the electrode rod body is connected to a power cord, and the electrode rod body is a chromium-nickel stainless steel rod body. Its structural design is reasonable, which can effectively improve the electroplating effect, and it avoids the phenomenon of entanglement with small products. At the same time, it will not have other adverse effects on the electroplated products. The electroplating has good conductivity and long service life. However, this electrode adopts a flat-topped cone structure. During the production process of metal-based grinding wheels, it cannot cooperate with the circular abrasive area of ​​the grinding wheel matrix, and a point discharge area is formed between the electrode and the grinding wheel matrix. The deposition area of ​​the abrasive and the metal coating is small, resulting in a slow abrasive plating process, and the formed abrasive layer has poor density, which affects the wear resistance and service life of the grinding wheel. Therefore, it is necessary to optimize the structure of this electrode to overcome the above-mentioned defects. Utility Model Content
