Electric spark machine tool capable of effectively avoiding damage caused by electric spark

Abstract

The invention relates to the technical field of electric spark machine tools, in particular to an electric spark machine tool capable of effectively avoiding damage caused by electric sparks. The electric spark machine tool comprises a box body, a first liquid storage box is arranged on the rear side of the box body, a first self-priming pump is arranged at the top of the first liquid storage box, a refrigeration box and a machining groove are arranged at the top of the box body, and a snakelike pipeline is arranged in the refrigeration box. The first self-priming pump is connected with the input end of the snakelike pipeline through a first liquid feeding pipe, the output end of the snakelike pipeline is connected with an immersion liquid input pipe, and a machining table is arranged in the middle of the bottom of the inner wall of the machining groove. According to the electric spark machine tool capable of effectively avoiding damage caused by electric sparks, machining liquid output by the first liquid storage box is cooled through the refrigeration box, and the machining liquid in the first liquid storage box is continuously output, so that the machining liquid in the machining groove is in a flowing state, and high temperature is avoided. Electric sparks generated when the electric spark machine tool works can be extinguished through a second self-priming pump, a second liquid storage tank, a connecting pipe, a gooseneck pipe and an atomizing nozzle, and generation of open fire is avoided.

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
