[0002] Wire cutting machine is a machine tool that uses the principle of electric sparks to process metal, and is mainly used to process metal parts with complex shapes. The wire cutting process uses a thin metal wire as an electrode and uses the electric sparks generated by the current to remove the workpiece material layer by layer, thereby achieving a high-precision and high-finish cutting effect.

[0003] According to a publicly disclosed positioning and guiding water spray device (publication number: CN107336074A), it includes a nozzle shell for left and right positioning and a water spray plate core for front and back positioning, and is positioned by a positioner on the deflector. Teflon is used instead of traditional plexiglass. The invention performs two-stage positioning through the nozzle shell and the water spray plate core, which is convenient for maintaining accurate positioning, and the fixation is stable and will not cause displacement. However, in the device, components such as the water spray plate core, the positioner and the plexiglass cooperate with each other, and it is difficult to achieve the effect of fixing the workpiece on the top of the operating table while spraying water to cool the top of the operating table. It is difficult to prevent the tool from being worn, deformed or damaged due to overheating, it is difficult to maintain cutting accuracy, and it is difficult to ensure the stability of the processing process.

In the present invention, the force of the extrusion rod moving downward by the upward displacement of the turntable cooperates with the compression spring, mounting plate, storage box and other components in the liquid replenishing device, so that the partition is squeezed by the upward displacement of the extrusion rod, causing the partition to move upward. At this time, a gap appears at the bottom of the storage box, so that the detergent inside the storage box drips into the water tank, achieving the effect of quantitatively replenishing the detergent, ensuring that the amount of detergent injected into the water tank is consistent each time, which helps to maintain stability during the processing and improve cutting efficiency and quality.

At this time, a gap appears at the bottom of the storage box 401, so that the detergent inside the storage box 401 drips into the water tank 204. When the turntable 306 moves downward, the partition 406 is reset by the elastic force of the compression spring 405 and the limit rod 404, thereby achieving the function of quantitatively replenishing the detergent.
