Variable thickness electrochemical discharge wire cutting machining device

The invention discloses a variable thickness electrochemical discharge wire cutting machining device, and belongs to the field of non-traditional machining. The variable thickness electrochemical discharge wire cutting machining device comprises tension control components, a row wire interval controllable device and a wire winding device. The row wire interval controllable device is located above a working solution box, row wire guiding wheels supporting and guiding the row wire interval controllable device are arranged in a working solution, the tension control components are arranged on the two sides of the working solution box, a fixed driving wheel and a wire storage cylinder of the wire winding device are located on the two sides of the working solution box respectively, a workpiece is installed on a main shaft, and the workpiece is cut by an electrode wire in the horizontal direction through the linkage between the axis Z and the axis Y. According to the variable thickness electrochemical discharge wire cutting machining device, the distance between the row wire guiding wheels immersed into the electrolyte solution can be adjusted in real time according to the thickness of a machined part, the control over the length of the electrode wire is achieved, it is ensured that the bubble generation process can be stable and reliable, machining efficiency is improved, the phenomenon that the electrode wire shakes due to the fact that the workpiece is too thin and the span of the electrode wire is large can be effectively avoided, and machining precision can be improved.
