Dielectric liquid filtration, separation and recovery device for electric spark piercer

Abstract

The invention relates to a dielectric liquid filtration, separation and recovery device for an electric spark piercer, which includes a collection device and a centrifugal separation device. The collection device includes a number of drainage holes set on a workbench, and a A water collection tank, the upper edge of the water collection tank is attached to the lower surface of the workbench, the side wall of the water collection tank is provided with a liquid outlet, and the liquid outlet is communicated with the centrifugal separation device through a pipeline, and the centrifugal separation The device is provided with a clear liquid outlet, and the electric spark piercer includes a dielectric liquid supply device, and the clear liquid outlet is connected with the dielectric liquid supply device. The invention has the effect that the dielectric liquid can be recycled after being filtered to effectively reduce the processing cost.

Description

technical field [0001] The invention relates to the field of electric spark perforation processing equipment, in particular to a dielectric fluid filtration, separation and recovery device for an electric spark perforator. Background technique [0002] At present, EDM is widely used in the processing of metal workpieces. EDM is a new type of processing technology that uses electric energy and heat energy for processing, and is also often called electrical discharge machining. The difference between EDM and general cutting is that there is no direct contact between the processing tool and the workpiece during EDM, but by the pulsed spark discharge continuously generated between the tool and the workpiece, and using the discharge generated during the discharge. The instantaneous local high temperature gradually erodes the metal material, and electric sparks visible to the naked eye will be generated during the discharge process. [0003] In the prior art, when the electric d...

Problems solved by technology

[0004] The above-mentioned prior art scheme has the following defects: since the waste debris generated during the process of erosion will be brought out with the flow of the dielectric, if the dielectric is a liquid, there will be Contains a large number of insoluble particles, and these insoluble particles will destroy the insulation of the dielectric fluid, and also reduce the fluidity of the dielectric fluid, so the dielectric fluid is often difficult to recycle, which increases the processing cost
