Vortex chip discharge electric discharge machine

Abstract

The invention relates to a vortex chip discharge electric discharge machine. The vortex chip discharge electric discharge machine comprises a pulse power supply, a tool electrode, a work piece electrode, a stand column, a lifting arm, a lifting shaft, an oil tank and a machine tool. The stand column is connected to the lifting arm, the lifting arm is connected to the lifting shaft, and the liftingshaft is arranged on the machine tool. The tool electrode and the work piece electrode are separately connected to the two poles of the pulse power supply, working fluid is arranged in the oil tank,the work piece electrode is immersed in the working fluid, a work piece platform is installed in the oil tank, and two work piece fixing grooves are formed in the upper end of the work piece platform.Discharge grooves are formed in the periphery of the work piece fixing grooves, vortex discharge modules are arranged in the work piece platform, the vortex discharge modules are separately connectedwith a first pump body and a second pump body, the first pump body is connected with an inlet of a liquid storage box after a filter is connected with the first pump body, and the second pump body isconnected to an outlet of the liquid storage box. According to the vortex chip discharge electric discharge machine, the problems that iron chips enter the oil tank and form precipitation, cleaning is not easy and much working fluid is polluted are solved due to the fact that vortexes are formed at the top of the discharge grooves in the work piece platform during pumping of the working fluid andthe iron chips are drawn out together through the vortex-shaped working fluid.

Description

technical field [0001] The invention belongs to a vortex chip removal electric discharge machine. Background technique [0002] EDM machine is a kind of mechanical processing equipment, mainly used for EDM processing. Widely used in the manufacture of various metal molds and mechanical equipment. The electric discharge machine is a special processing method that uses the electric erosion effect produced by the pulse discharge between the two electrodes immersed in the working fluid to erode the conductive material, also known as electric discharge machining or electric erosion machining. [0003] The Chinese patent application number is: 20141075519.4, and the applicant: Wuhu Wanhua Plastic Products Co., Ltd. discloses an electric discharge machine, including a pulse power supply, a tool electrode, a workpiece electrode, a column, a lifting arm, a lifting shaft, a fuel tank, and a machine tool. The column is connected to the lifting arm, the lifting arm is connected to the...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to solve the above problems and provide a vortex chip removal EDM machine. When the working fluid is pumped, a vortex is formed above the discharge groove in the workpiece platform, and the vortex-shaped working fluid will extract the iron filings together, avoiding the Iron filings enter the oil tank, forming precipitates, making it difficult to clean, and polluting more working fluids, etc.
