Electrolytic machining method, cathode for electrolytic machining and electrolytic machining device

Abstract

The invention discloses an electrolytic machining method, a cathode for electrolytic machining and an electrolytic machining device. The method comprises the steps that a part serves as an anode, an electrolyte is introduced into an internal structure from a surface port of the part, the electrolyte makes contact with the inner wall of the internal structure for a reaction, then the electrolyte flows out of the other surface port of the part and continues to flow through the cathode arranged at the other surface port, an electrolytic machining loop is formed, and the internal structure of the part is treated; the disclosed cathode is provided with an electrolyte collection container, and the collection container is provided with an electrolyte collection port and an electrolyte outflow port; and the electrolytic machining device comprises the cathode and an electrolyte tank. According to the method, a workpiece is machined and formed on the basis of an oxygen electrode metal electrochemical dissolution principle, the efficient and precise machining problem of internal structure metal parts such as titanium alloy and high-temperature alloy manufactured through laser additive manufacturing is effectively solved, and the metal workpiece internal structure surface high in precision and good in surface quality can be effectively machined.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an electrolytic processing device for internal channel structural parts. Background technique [0002] Internal structural parts (also referred to herein as parts) refer to metal parts including a body and an internal structure inside the body, at least two ports on the surface of the body, and the at least two ports communicated through the internal structure. The internal structure includes but is not limited to flow channel structures, such as straight flow channels, curved flow channels, spiral flow channels, irregular linear flow channels, etc., at least two ports provided on the surface of the part body communicate through the above flow channels ; It is also possible to set multiple parallel flow channels inside the part body, each flow channel has an independent inlet and outlet, or multiple flow channels share the flow channel or share the port. The usual ...

AI Technical Summary

Problems solved by technology

For example, for internal flow channel structural parts, slag and foreign matter often appear in the flow channel after pre-processing. Since the inner diameter of the flow channel is small, it is difficult to deal with the roughness of the inner wall, slag and foreign matter.
