Novel electrolytic milling method and device for machined gap through electrolyte wall-attaching direct spraying

Abstract

The invention discloses an electrolytic milling method for a machined gap through electrolyte wall-attaching direct spraying. The front wall face of the front end in the feeding direction of a cathodemachining section is used for machining a workpiece, an electrolyte comes out from a liquid spraying opening in the bottom of a cathode body on the upper part of the cathode machining section and isdirectly sprayed to enter a machining area in the mode of closely attaching a cathode machining face, namely wall-attaching direct spraying, and thus the kinetic energy loss caused by electrolyte steering is avoided. The liquid supplying mode is extremely simple, compared with ordinary metal milling, milling can be conducted more flexibly, the high-speed and large-flow electrolyte can enter the machining area at the minimum loss, and thus the electrolytic machining speed is increased in a multiplied mode. The invention further discloses an electrolytic milling device implementing the electrolytic milling method, the electrolytic milling device comprises the cathode body, and the cathode machining section is arranged at the lower end of the cathode body; feeding is conducted according to aset trajectory; the inner side face of the liquid spraying opening in the lower end face of a cathode clamping body and the front wall face of the cathode machining section are located on the same plane, and the electrolyte sprayed from the liquid spraying opening is directly sprayed to enter the machining area in the mode of closely attaching the front wall face of the cathode machining section.

Description

technical field [0001] The invention relates to an electrolytic milling method and a device thereof, in particular to an electrolytic milling method and a device thereof in which an electrolyte solution is adhered to a wall and directly sprayed to process gaps. Background technique [0002] Electrolytic milling uses a simple cathode to form the workpiece surface through the envelope surface of the cathode movement trajectory, which has the advantages of large flexibility and short preparation period. The existing liquid supply methods for electrolytic milling are mainly divided into internal spray liquid supply and external spray liquid supply. For the electrolytic milling device and method of internal spray liquid supply, the electrolyte enters the processing area after turning 90° or at a certain angle after coming out of the nozzle. In the electrolytic milling device and method using external spray liquid supply, the electrolyte also enters the processing area through a ...

Problems solved by technology

In the electrolytic milling device and method using external spray liquid supply, the electrolyte also enters the processing area through a turning point, or enters the front processing area from the rear of the feeding direction. In both ways, the working fluid is not directly sprayed into the processing area. The loss of kinetic energy during the movement is huge, and the processing area cannot obtain high-speed and large-flow electrolyte, which can only reduce the processing efficiency to ensure the stability of the processing process
