Technical Field

[0001] The utility model relates to the field of mechanical processing equipment, in particular to an adjustable chip removing device for a working liquid tank of an electric spark forming machine. Background Art

[0002] The EDM machine is a special processing method that uses the electro-erosion effect generated by the pulse discharge between two electrodes immersed in the working fluid to remove conductive materials. During the EDM process, the working fluid plays a role in cooling and chip removal. The iron chips generated by the workpiece circulate with the working fluid. When the waste chips in the working fluid accumulate to a certain extent, the iron chips in the working fluid will affect the discharge state of the EDM, and even cause the channel to be blocked, seriously affecting the discharge effect and the surface quality of the processed workpiece. At the same time, the iron chips are mixed in the working fluid, which is not conducive to the recovery and reuse of the working fluid;

[0003] At present, in order to remove iron filings mixed in the working fluid in the prior art, a filter is usually set in the working fluid tank. However, after long-term use, the accumulated iron filings will clog the filter, affecting the normal circulation of the working fluid.

[0004] Therefore, an adjustable chip removal device for the working liquid tank of an EDM machine is proposed to solve the above problems. Utility Model Content
