Device for electrochemical machining of template

Abstract

The invention discloses a device for electrochemical machining of a template. The device comprises a fixture and the template, and an electrolyte flow chamber is formed between the fixture and the template; and the electrolyte flow chamber is internally provided with a group of metal columns connected with a negative electrode of a power supply, and the outer wall of each metal column is providedwith a circle of convex teeth. The convex teeth on the metal columns are inclined to the same direction. The electrolyte flow chamber is internally provided with a liquid inlet and a liquid outlet separately, and the rotation direction of the metal columns is consistent with the flow direction of electrolytes; and the inclination direction of the convex teeth is consistent with the rotation direction of the metal columns. According to the device, electrolytic products between the negative electrode and a positive electrode are directly stirred through mechanical motion, so that the mass transfer efficiency of the electrolytic products in an electrolyte flow field is improved.

Problems solved by technology

However, existing studies have shown that when the flow rate of the electrolyte reaches 25m / s, the effect of further increasing the flow rate or pressure of the electrolyte on the mass transfer rate of the product will no longer be significant; in addition, the product after electrolysis of some metal materials has a high viscosity and is easily Adhesive to the metal surface, high-speed electrolyte flow is difficult to remove it in time, hindering the continuous progress of electrolytic machining, thus affecting the processing quality of template electrolytic machining
