Abstract

The invention relates to a system and a method for continuous electrolysis processing of microgroove groups of a flexible metal sheet, and belongs to the technical field of electrolysis processing. The system comprises a flexible metal sheet workpiece conveying system, an electrolysis processing tool electrode system, a processing power source, an electrolyte circulating system, and an electrolysis processing machine tool. The method comprises the following steps of during processing, firstly, clamping the flexible metal sheet, enabling the flexible metal sheet to penetrate between a plurality of support rollers and an arc-shaped masking plate, and enabling the inner and outer surfaces to tightly attach with the corresponding support rollers and the arc-shaped masking plate; according to the structure and size of each microgroove group, selecting a tool electrode, and completing the clamping; flushing electrolyte, feeding each tool electrode along the radial direction of the corresponding support roller, and processing a groove structure in the surface of the flexile metal sheet; processing to the specified depth, enabling a driving wheel to continuously rotate, and driving the flexible metal sheet to slowly slide along the tangential direction of each roller, so as to complete the continuous processing of the microgroove groups of the flexible metal sheet. The system and the method have the advantages that the tool electrodes can be synchronously performed with auxiliary movement, and the updating of electrolyte and the discharging of electrolysis products are promoted.

Description

technical field [0001] The invention relates to a continuous electrolytic machining system and method for micro-group grooves of flexible metal sheets, belonging to the technical field of electrolytic machining. Background technique [0002] Micro-scale groove structures widely exist in important parts in aerospace, instrumentation and other fields, and most of them appear as group groove structures. In order to meet the needs of use, titanium alloys, high-temperature alloys, stainless steel and other difficult-to-machine materials are generally used. The manufacture of such difficult-to-machine materials with micro-groove structures poses a great challenge to the existing processing technology, and has become a research hotspot and difficulty. [0003] Researchers at home and abroad have proposed a variety of process methods to improve the processing quality and processing efficiency of the micro-groove structure. Plastic forming is a common processing method for micro-gr...
