[0002] A wire EDM machine, also known as a wire EDM cutting machine or wire EDM machine, is a process testing instrument used in the field of mechanical engineering. Wire EDM uses a continuously moving fine metal electrode wire as the electrode to perform pulsed spark discharge on the workpiece, generating high temperatures to erode the metal and cut it into shape. The principle of wire EDM is based on the gap between the wire electrode and the workpiece, where continuous discharge removes metal. During the operation of the wire EDM machine, cooling water is needed to lower the temperature. As the cooling water circulates, heat needs to be removed to maintain its low temperature; therefore, a low-temperature maintaining device for the cooling water in the wire EDM machine is required.

[0003] Existing technologies have the following problems:

[0004] Existing low-temperature maintaining devices for cooling water in wire EDM machines typically remove heat from the cooling water by blowing air through a blower. However, in practical applications, this single method is ineffective in cooling the water and fails to maintain its low temperature, hindering its widespread adoption. Utility Model Content

A circulating water pipe 9 is fixedly connected to the inner surface of the cooling plate 8. A first cold air pipe 10 is fixedly connected to the front surface of the cooling plate 8.

[0025] During use, cooling water is discharged from the outlet pipe 11 on one side of the slow wire EDM machine body 2 into the dispersion pipe 4. At this time, the discharged cooling water is discharged through the dispersion head below the multiple dispersion pipes 4, which increases the heat dissipation area. The fan motor 52 drives the fan blades 53 to rotate, generating airflow to cool down the falling cooling water.

[0026] As a preferred technical solution for the low-temperature holding device for cooling water of the slow wire EDM machine of this utility model, a liquid outlet pipe 11 is provided on one side of the slow wire EDM machine body 2. One end of the liquid outlet pipe 11 is fixedly connected to the dispersion pipe 4, and a dispersion head is fixedly connected to the bottom surface of the dispersion pipe 4. The water in the liquid outlet pipe 11 enters the dispersion pipe 4 and is discharged through the dispersion head. The inner cavity of the dispersion head is a conical hollow tube.

[0027] As a preferred technical solution for the low-temperature holding device for cooling water of the wire EDM machine of this utility model, the blower mechanism 5 includes a blower shroud 51 that is fixedly connected to one side surface of the water tank 3, and a blower motor 52 is fixedly connected to one side surface of the blower shroud 51; the inner cavity of the blower shroud 51 is provided with a blower fan blade 53, and one end of the blower fan blade 53 is fixedly connected to the output end of the blower motor 52; a through hole is provided on the side surface of the blower shroud 51 away from the water tank 3 to ensure that the blower motor 52 drives the rotation of the blower fan blade 53 to generate airflow.

[0028] As a preferred technical solution for the low-temperature maintaining device for cooling water of the wire EDM machine of this utility model, the pump 6 has a pumping pipe fixedly connected to its pumping end, and the pumping end is fixedly connected to the circulating water pipe 9 via a flexible hose; an inlet pipe 13 is provided on one side of the wire EDM machine body 2, and the outlet end of the circulating water pipe 9 is fixedly connected to the inlet pipe 13; one end of the pumping pipe is fixedly connected to the water storage tank 3 and is located at the bottom of the inner cavity of the water storage tank 3.

[0029] Example 2

[0030] Please see Figure 1 and Figure 3 The difference between this embodiment and Embodiment 1 is that:

[0031] The heat sink 74 has heat dissipation holes through its surface on the side away from the cooling plate 71. The bottom surface of the heat sink 74 and the bottom surface of the cold air cover 73 are both fixedly connected to the support platform 1. The top surface of the water tank 3 is fixedly connected to the second cold air pipe 12. The air outlet end of the air outlet pipe 76 is fixedly connected to the first cold air pipe 10 and the second cold air pipe 12 respectively. The cooling surface of the semiconductor refrigeration chip 72 faces the cold air cover 73, and the heating surface of the semiconductor refrigeration chip 72 faces the heat sink 74. The air blown by the blower 75 behind the heat sink 74 cools the heating surface of the semiconductor refrigeration chip 72. The blower 75 behind the cold air cover 73 blows the cold air into the air outlet pipe 76, and then into the first cold air pipe 10 and the second cold air pipe 12.

[0032] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as the blower motor 52, water pump 6, thermoelectric cooler 72, blower 75, etc., should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0033] The working principle and usage process of this utility model are as follows: When in use, after the water in the dispersion pipe 4 falls into the inner cavity of the water storage tank 3, the water pump 6, blower 75 and semiconductor cooling chip 72 start synchronously. The water pump 6 pumps the water into the circulating water pipe 9 through the liquid extraction pipe. At this time, the blower 75 on the back side of the cold air cover 73 blows cold air into the air outlet pipe 76, and then into the first cold air pipe 10 and the second cold air pipe 12. The second cold air pipe 12 discharges the cold air directly into the water storage tank 3 to cool the cooling water. The first cold air pipe 10 blows the cold air towards the circulating water pipe 9 to cool the water in the circulating water pipe 9. The cooling plate 8 has a through hole on the back side to improve the heat dissipation effect of the circulating water pipe 9. That is, after the cooling water is cooled by the blower mechanism 5, it is cooled by the cold air blown out by the second cold air pipe 12. Under the action of the water pump 6, it is pumped into the circulating water pipe 9. The first cold air pipe 10 blows out cold air for further cooling, thereby keeping the cooling water at a low temperature.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
