Abstract

The invention discloses a blisk electrolysis slotting machining annular electrode and a technology method. The slotting machining annular electrode is composed of an electrolyte slot (1), an HSK hydraulic chuck (2), a through connection disc (3), an electrolyte draining valve (4), an electrolyte overflow opening (5), an electrolyte slot front baffle (6), a working cathode component and a base (7). The working cathode component is composed of a sacrificial anode protection plate (8), two electrolyte inlet pipe joints (9), insulation pressing blocks (10) and working cathodes (11). The electrolyte inlet pipe joints (9) are connected with the working cathodes (11) respectively through the insulation pressing blocks (10). The blisk electrolysis slotting machining annular electrode and the technology method solve the problems that a traditional machining method is low in efficiency, high in cost and unstable in quality.

Description

technical field [0001] The invention relates to the technical field of structural design and application of ring electrodes for electrolytic grooving of integral blisks, and in particular provides a ring electrode for electrolytic grooving of integral blisks and a process method. 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 supply 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 the charge exchange occurs between the tool and the workpiece. The material of the anode workpiece is dissolved and taken away by the high-speed flowing electrolyte, thereby achieving very precise processing requirements. [0003] It is urgentl...
