The invention discloses an electrolytic machining electrolyte current-sharing array group hole cathode and a manufacturing method thereof, and belongs to the field of cathode for electrolytic machining. The electrolytic machining electrolyte current-sharing array group hole cathode comprises an end cover, a flow equalizing barrel, a base, a spring piece, a cathode support and a group hole cathodetube, the electrolyte enters the stirring cavity from the liquid inlet hole, the spring piece is impacted in the stirring cavity to enable the spring piece to vibrate and stir the electrolyte, the stirred electrolyte is evenly divided into a plurality of branch streams through the dense filtering layer, a stable flowing layer flow is formed in the dense filtering layer, and the laminar flow is conveyed into the group hole cathode pipe through the buffer cavity to be subjected to electrolytic group hole processing. Through the adoption of the structure, before the electrolyte enters the group-hole cathode pipe for electrolytic machining, the electrolyte is subjected to oscillation stirring and flow-sharing laminar flow stabilization in sequence, so that the stability of the electrolyte flowfield is improved, the method solves the problem that the cathode is easy to short circuit in the group hole machining process, improves the machining quality of the array group hole electrolytic machining, and has the advantages of being simple in structure, stable in flow field, strong in practicability and the like.
Description
technical field [0001] The invention relates to a cathode for electrolytic machining and a manufacturing method thereof, more specifically, to an electrolytic machining electrolyte flow equalizing array group hole cathode and a manufacturing method thereof. Background technique [0002] Electrolytic machining is the use of the principle that metals can undergo anodic dissolution in electrolytes to process parts into shapes. It has the following advantages: (1) almost all conductive materials can be processed, the hardness, strength and toughness of the processed material can be ignored, and the metallographic structure of the processed material basically does not change; (2) there is no Macroscopic force, so there is no processing deformation and stress, especially suitable for processing thin-walled parts; (3) No tool cathode consumption; (4) Simple tooling and easy operation. Therefore, this processing method is widely used in aerospace, military, medical and other fields...
