Abstract

The invention provides an electrolytic machining process method for an open type blisk. The electrolytic machining process method comprises the following steps of performing electrolytic machining bytaking the open type blisk as a workpiece anode, taking a machining tool as a tool cathode, connecting the workpiece anode with a power supply anode and connecting the tool cathode with a power supplycathode, wherein an insulating layer on the tool cathode is made of thermosetting polyether-ether-ketone. Stable and continuous electrolytic machining of the open type blisk is achieved, it is guaranteed that the machining precision and the machining quality of the blade profile meet the technological design requirements, and the defects that an existing open type blisk electrolytic machining process is frequently interrupted, short-circuit faults are prone to occurring, and the electrolytic machining efficiency is low are overcome.

Description

technical field [0001] The invention relates to electrolytic machining, in particular to an electrolytic machining process for an open integral blisk. Background technique [0002] Electrolytic machining is to connect the anode of the workpiece to the positive pole of the power supply, and the cathode of the tool to the negative pole of the power supply. Under the dual action of the electric field and the flow field between the positive and negative poles, the cathode of the tool is used to copy the surface of the cathode of the tool to the anode of the workpiece. , to achieve the purpose of forming processing. [0003] The open blisk has a complex structure and a large number of blades. The forming method is to electrolytically process one blade at a time, and then complete the electrolytic machining of the remaining blades in turn. Therefore, the stability and continuity of the electrolytic machining process is to ensure the quality of electrolytic machining and electrolyt...
