Abstract

The invention relates to a snakelike runner movable formwork cluster hole electrochemical machining device and a machining method and belongs to the technical field of electrochemical machining. The snakelike runner movable formwork cluster hole electrochemical machine device and machining method are characterized in that a traditional wide runner is changed into a snakelike runner, the runner is narrowed, and flow field distribution evenness on the cross section of the runner in a machining area is improved; the flow velocity of the machining area is relatively improved, machined products can be fast discharged, electric field and flow field parameters are reasonably selected, the flow field state of the machining area can be stable, and machining quality is improved. The machining device comprises a power supply, an electrolyte circulation system, an electrochemical machining machine tool, a mask plate negative electrode and a tool clamp. The snakelike runner movable formwork cluster hole electrochemical machining device and the machining method have important significance in improving the cluster hole electrochemical machining flow field distribution evenness and ensuring that a large-area thin-wall hole plate can be machined at a time.

Description

Technical field

[0001] The invention relates to an electrolytic machining device and a machining method for a group of holes in a movable template of a serpentine flow channel, and belongs to the technical field of electrolytic machining. Background technique

[0002] At present, the common group hole processing methods are: mechanical processing, laser processing, EDM, electrochemical jet processing, photographic electrolytic processing, etc. However, the above-mentioned methods all have some deficiencies that are difficult to overcome when processing the multi-hole structure of the thin plate of difficult-to-cut materials. For example, deformation is easy to occur due to the concentration of residual stress in mechanical processing; there is a heat-affected zone on the surface of the workpiece processed by laser processing technology and EDM technology, and the workpiece is prone to thermal deformation resulting in microcracks; Fragile, not suitable for array porous proce...
