An electric discharge machine tool that can effectively avoid damage caused by electric sparks

Abstract

The invention relates to the technical field of electric discharge machine tools, in particular to an electric discharge machine tool capable of effectively avoiding damage caused by electric sparks. There is a first self-priming pump, the top of the box is equipped with a refrigeration box and a processing tank, and a serpentine pipeline is arranged in the refrigeration box. The first self-priming pump is connected to the input end of the serpentine pipeline through the first liquid delivery pipe, and the serpentine The output end of the pipeline is connected with the immersion liquid input pipe, and the middle part of the bottom of the inner wall of the processing tank is provided with a processing table. The EDM machine tool, which can effectively avoid damage caused by electric sparks, cools down the processing fluid output from the first liquid storage tank through the refrigeration box, and the processing fluid in the first liquid storage tank is continuously output, so that the processing in the processing tank The liquid is in a flowing state to avoid high temperature. The electric spark generated when the EDM machine is working can be extinguished through the second self-priming pump, the second liquid storage tank, the connecting pipe, the gooseneck and the atomizing nozzle to avoid open flames. generation.

Description

technical field [0001] The invention relates to the technical field of electric discharge machine tools, in particular to an electric discharge machine tool which can effectively avoid damage caused by electric sparks. Background technique [0002] EDM machine tool is a kind of electric processing equipment, its basic physical principle is that free positive ions and electrons accumulate in the field, and soon form an ionized conductive channel, at this stage, a current is formed between the two plates, resulting in countless occurrences between particles Collision forms a plasma region, and quickly rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some materials on the surface of the two conductors, and at the same time, due to the vaporization of the electrodes and dielectric fluid, a bubble is formed, and its pressure rises regularly Until it is very high; then the current is interrupted, the temperature suddenly drops, causing the bubble to explod...

Problems solved by technology

[0004] The purpose of the present invention is to provide an electric discharge machine tool that can effectively avoid damage caused by electric sparks, to solve the problem that the existing machining fluid injection method proposed in the background technology has limited effect on the elimination of electric sparks, and the existing electric discharge machine tools The dielectric fluid in the machining tank is injected well during processing. Long-term processing will cause the temperature of the dielectric fluid to rise, and the high-temperature dielectric fluid will transfer the temperature to the machine tool, which will cause certain damage to the EDM machine tool. In severe cases, it may cause damage to the components inside the EDM machine tool
