Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] The premise of the embodiment of the present invention is that on the basis of using electrolysis or other methods to groove the overall blisk, the margin of the blade profile is basically controlled at 1-1.5mm. The embodiments of the present invention mainly focus on finishing the blade profiles of the integral blisk, as well as the difficult-to-machine front and rear edges and flow channels. The embodiment of the present invention is based on a multi-axis high-frequency narrow-pulse fine vibration electrolysis machine tool.

[0034] Such as figure 1 As shown, an electrode for fine electrolytic machining of an integral blisk leaf type, the device includes a left electrode device 1 and a right electrode device 2;

[0035] Such as figure 2 As shown, the left electrode device 1 includes an HSK high-precision hydraulic chuck 1-1, a first auxiliary liquid supply...

Abstract

The invention discloses a blisk blade profile subtle electrochemical machining electrode and a machining method. The device comprises a left electrode device and a right electrode device, wherein the left electrode device comprises an HSK high-precision hydraulic chuck, a first auxiliary liquid supply module, a blade back working cathode, a lower insulating baffle, an electrode base, a transfer base and an upper insulating baffle; and the right electrode device comprises an HSK high-precision hydraulic chuck, an electrode base, a transfer base, a sealing baffle, a second auxiliary liquid supply module, a main liquid supply module, a blade basin working cathode and an upper insulating baffle. According to the invention, through the vibrating electrochemical machining of the left and right electrodes, the final machine shaping of the blisk blade profile surface is finished, the machining efficiency can be improved by 50% compared with that of the traditional machining method, and allowance-free shaping is realized.

Description

technical field [0001] The invention belongs to the technical field of electrolytic machining, and in particular relates to an electrode and a processing method for fine electrolytic machining of integral blisk blades in the aviation field. Background technique [0002] The principle of electrolytic machining is a non-traditional cutting method that uses the principle that metals can undergo anodic dissolution in the electrolyte to remove materials and shape workpieces. In electrolytic machining, the tool (knife) is connected to a DC power source as the cathode and the workpiece as the anode. In the electrolyte, the cathode of the tool moves to the anode of the workpiece at a certain speed, and an electric charge exchange occurs between the tool and the workpiece. The anode workpiece is dissolved and taken away by the high-speed flowing electrolyte, thereby achieving very precise processing requirements. [0003] The whole blisk is processed by electrolysis method, which is...
