Additive Manufacturing Metal Rough Surface Electrolytic EDM Composite Leveling Tool and Method

Abstract

The invention relates to an additive manufacturing metal rough surface electrolysis electric spark composite leveling tool and method, and belongs to the electric spark electrolysis processing technology field. An extremely non-leveling surface of additive manufacturing metal is continuously leveled and processed through an electrolysis-electric spark-electrolysis composite process new method. Firstly, an extreme high point on a surface of a workpiece is preliminarily leveled through pipe electrode large-gap jet flow electrolytic processing; after that, the relatively high points are rapidly discharged through an electric spark electrode so that further leveling is performed; and finally, the rough and leveled surface after electric spark processing is further electrolyzed and processed sothat the surface is smooth through a tube electrode. Therefore, a purpose of efficiently leveling and finishing the rough surface of the additive manufacturing metal is achieved. Through electrolysis-electric spark-electrolysis continuous processing, the surface of the additive manufacturing metal can be efficiently leveled and smoothed, and the tool and the method has important significance in improving the processing efficiency of the additive manufacturing metal.

Description

Problems solved by technology

In the time difference, the surface processed by EDM may form an oxide layer again, which will hinder the efficient operation of subsequent electrolytic machining

In addition, after EDM, no matter other tools or equipment are used for electrolytic machining, operations such as tool setting must be performed first, which will consume a certain amount of time and reduce processing efficiency

For EDM-electrolysis composite machining, the current research is mainly on the removal of materials by EDM, supplemented by the removal of the recast layer of EDM through electrolysis. Most of the solutions used are ultra-low concentration salt solutions, which cannot be achieved through High-efficiency electrolysis; some scholars try to use the low-concentration solution required for electric spark discharge and the high-concentration solution required for electrolysis to realize composite electrolytic processing at the same time during processing, but after this method is processed, two solutions with different concentrations are mixed in the Together, it cannot be reused, which is not conducive to long-term mass industrial production
