[0002] Wire EDM is a special machine tool used for cutting and processing metal workpieces. During use, high temperatures are generated due to the special method of wire EDM.

[0003] Chinese utility model patent: Publication number CN213857499U discloses a new type of electric spark wire cutting machine, including a cutting machine body, a cooling box is fixedly connected to the lower end of the front side wall of the cutting machine body, a partition is fixedly provided on both the left and right sides of the interior of the cooling box and is divided into a filter chamber, a cooling chamber and a liquid storage chamber from left to right through the two partitions, a U-shaped liquid baffle plate is fixedly provided on the upper end of the workbench of the cutting machine body, a return pipe is fixedly connected to the lower end of the front side wall of the U-shaped liquid baffle plate, and the end of the return pipe away from the U-shaped liquid baffle plate passes through the upper side wall of the filter chamber and extends to the interior, and a filter screen is fixedly provided on the upper part of the interior of the filter chamber.

[0004] In the existing technology, CN213857499U, when in use, filters, refluxes and cools the coolant, so that the coolant can be recycled and the cooling effect is guaranteed, which greatly reduces the waste of the coolant. At the same time, the cooling efficiency of the coolant is high, which is beneficial to the cooling of the electric spark cutting machine.

[0005] However, in the prior art, when cooling the coolant, the device injects cold air into the cooling box through a cold air blower to cool the coolant. However, the internal space of the cooling box is limited, and under a sealed condition, the injection amount of cold air is limited, which leads to low cooling efficiency of the coolant. In addition, when the cutting machine is working at high power, the coolant needs to circulate at a higher speed, which leads to the coolant being unable to be cooled in time, resulting in a high temperature at the workpiece, thereby affecting the processing efficiency. Therefore, a high temperature protection device for an electric spark wire cutting machine is proposed to solve the above problems. Utility Model Content

When the heat dissipation fan 11 is started, the cooling pipe 10 can be air-cooled by the mirror-mounted heat dissipation fan 11, so that the temperature of the coolant is reduced when flowing through the cooling pipe 10, thereby achieving continuous cooling of the workpiece. The larger air flow rate improves the cooling efficiency of the coolant flowing in the cooling pipe 10, thereby achieving the effect of improving the cooling efficiency of the coolant used for workpiece processing cooling.

[0049] When the utility model is used, the processing end of the cutting machine body is located in the processing bin 5, and a large amount of coolant is injected into the liquid storage bin 1, and the coolant level in the processing bin 5 is made equal to the coolant level in the liquid storage bin 1 through the cooling pipe 10. During the processing, the coolant can be transported to the spray system through the pump body 15 through the discharge pipe 3, and the coolant is sprayed on the workpiece through the spray system, so that the workpiece can be cooled by the coolant.
