Abstract

The invention discloses a laminated roller type electrode electrolytic machining system and method for a metal plate with micro group grooves, and belongs to the technical field of electrolytic machining. The system comprises an electrolytic power supply, laminated roller type electrodes, an electrode driving assembly connected to the laminated roller type electrodes, and an electrolyte circulating assembly. According to the system, the machining efficiency of the micro group grooves is effectively improved; a plurality of independent micro flow channel machining areas are formed by adopting the laminated roller type electrodes, so that respective regulation and control can be performed according to actual requirements, and the processing effect of other areas is not influenced; insulating layers are arranged on the two sides of a conducting layer and are tightly attached to a workpiece, so that material removal in a non-machining area is effectively inhibited, and machining defects such as secondary machining and stray corrosion in a non-machining area are reduced; high-precision machining with smaller groove width and lower stray corrosion is realized; and the electrodes are easy to manufacture, long in service life, low in machining environment requirement, capable of being repeatedly used for multiple times and free of replacement.

Description

technical field [0001] The invention relates to the technical field of electrolytic processing, in particular to a stacked roller electrode electrolytic processing system and method with fine group grooves on a metal plate. Background technique [0002] The micro-groove structure on the surface makes the parts more excellent than smooth surfaces in terms of heat transfer characteristics, energy conversion characteristics, chemical reaction characteristics, bionic characteristics, friction characteristics, etc., and has great application potential, such as proton exchange membrane fuel cells. The core components are bipolar plates, heat transfer tubes, microfluidic chips, piston rings and coolers, etc. However, the processing of micro-groove structures, especially on difficult-to-machine materials, such as manufacturing microstructures on superalloys, titanium alloys, and stainless steels, is a difficult problem in the manufacturing industry. [0003] At present, the process...
