Description

Technical Field

[0001] This utility model belongs to the field of wire electrical discharge machining technology, and in particular relates to a high-temperature protection device for wire electrical discharge machining machine tools. Background Technology

[0002] Wire electrical discharge machining (EDM) machines are specialized machine tools used for cutting and machining metal workpieces. During operation, the unique nature of wire EDM generates high temperatures. Current EDM systems typically spray coolant continuously during workpiece cutting to provide high-temperature protection. However, in actual use, the coolant needs to circulate at a high speed, and if it cannot cool down quickly enough, the workpiece temperature remains high, resulting in inadequate high-temperature protection.

[0003] In addition, existing wire electrical discharge machining (EDM) processes generate high-temperature exhaust gases, which can affect the health of workers and pose a safety hazard.

[0004] To address this issue, we propose a high-temperature protection device for wire EDM machines. Utility Model Content

[0005] The purpose of this invention is to solve the problem of unsatisfactory protection effect in the existing technology, and to propose a high-temperature protection device for wire EDM machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-temperature protection device for an electrical discharge wire cutting machine includes an open-top operating chamber. A top plate is fixedly connected to one side of the top surface of the operating chamber. A vent hole is opened through the top surface of the top plate. A filter box with an open bottom is fixedly connected to the top surface above the vent hole. A gas filter plate is installed inside the filter box. A ventilation pipe is fixedly connected to the top of the filter box. A horn-shaped ventilation hood is fixedly connected to the other end of the ventilation pipe.

[0008] The operating chamber is provided with a connecting pipe facing one side. The end of the connecting pipe away from the operating chamber is connected to a radiator, and the radiator is fixedly installed inside the ventilation hood. A fan is fixedly installed on one side of the radiator. A drain pipe extending upward is fixedly connected to the outlet of the radiator. A water pump connected to the connecting pipe is fixedly installed inside the operating chamber.

[0009] Preferably, the fan is located on the side of the radiator facing the ventilation duct, and the fan blows air towards the side of the radiator.

[0010] Preferably, a flange that matches the radiator is fixedly connected to the middle of the inner side of the ventilation hood.

[0011] Preferably, a liquid filter plate is fixedly installed inside the operating chamber below the top plate, and the vent and the connecting pipe are located on both sides of the filter plate.

[0012] Preferably, hinge plates are hinged to both sides of the top surface of the operating compartment, and a limiting block extends inward from the inner sidewall of the top of the operating compartment.

[0013] Preferably, the hinge plate is L-shaped.

[0014] In summary, the technical effects and advantages of this utility model are as follows: This high-temperature protection device for wire EDM machines uses a water pump to circulate the coolant from the operating chamber to the drain pipe for reuse. A cooling radiator and fan work together to cool the coolant after use. Simultaneously, a negative pressure is created around the vents using a filter box and ventilation pipe, drawing the exhaust gas generated by wire cutting into the filter box and filtering it with a gas filter plate. Compared to existing devices, this avoids the problems of coolant not cooling down in time and exhaust gas dispersion, thus improving the protective performance. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3A high-temperature protection device for an electrical discharge wire cutting machine includes an operating chamber 1 with an open top surface. A top plate 2 is fixedly connected to one side of the top surface of the operating chamber 1. A ventilation hole 3 is opened through the top surface of the top plate 2. A filter box 4 with an open bottom surface is fixedly connected to the top surface above the ventilation hole 3. A gas filter plate 5 is installed inside the filter box 4. A ventilation pipe 6 is fixedly connected to the top of the filter box 4. A horn-shaped ventilation cover 7 is fixedly connected to the other end of the ventilation pipe 6.

[0022] Reference Figure 2-4 The operating chamber 1 has a connecting pipe 8 facing one side. The end of the connecting pipe 8 away from the operating chamber 1 is connected to a cooling radiator 9, which is fixedly installed inside the ventilation hood 7. A fan 11 is fixedly installed on one side of the cooling radiator 9, and an upward-extending drain pipe 12 is fixedly connected to the outlet of the cooling radiator 9. A water pump 10 connected to the connecting pipe 8 is fixedly installed inside the operating chamber 1. The cooling radiator 9 is existing technology, featuring a winding water channel inside to increase the contact area with air and facilitate heat dissipation of the coolant.

[0023] It should be noted that this device should be used in conjunction with an electrical discharge wire cutting machine. The electrical discharge wire cutting machine includes a conductive wire, a drive assembly for moving the conductive wire, and an energizing assembly for applying pulsed current to the conductive wire. This type of electrical discharge wire cutting machine is existing technology and common in the field; it is easily understood by those skilled in the art, and therefore will not be described in detail. The top end of the drain pipe 12 should be fixedly connected directly above the cutting section of the conductive wire.

[0024] The high-temperature protection device for this wire EDM machine requires coolant to be injected into the operating chamber 1 before use. During wire cutting, the water pump 10 and fan 11 are turned on. The water pump 10 pumps the coolant in the operating chamber 1 into the connecting pipe 8, and then into the radiator 9 through the connecting pipe 8. The fan 11 blows air onto the radiator 9, which cools the coolant. The cooled coolant is then sprayed onto the cutting section of the conductive wire through the drain pipe 12, thus achieving high-temperature protection. At the same time, the fan 11, together with the ventilation pipe 6 and the ventilation hood 7, creates a negative pressure at the vent 3. The exhaust gas generated by wire cutting is drawn into the vent 3, filtered by the gas filter plate 5, and then blown onto the radiator 9, achieving efficient use of space.

[0025] Reference Figure 1-3 The fan 11 is located on the side of the radiator 9 facing the ventilation pipe 6, and the fan 11 blows air towards the side of the radiator 9. Compared with the suction type, the blowing type has a better heat dissipation effect on the radiator 9. Moreover, the blowing type design allows the fan 11 to be closer to the ventilation pipe 6 than the suction type, ensuring the negative pressure suction effect of exhaust gas.

[0026] A flange 13 is fixedly connected to the center of the inner side of the ventilation shroud 7 to match the radiator 9. The radiator 9 can be easily fixedly installed on the flange 13 to achieve fixed installation of the radiator 9 inside the ventilation shroud 7. The flange 13 can also work with the edge of the radiator 9 to ensure the stability of the airflow path of the ventilation shroud 7, preventing air from blowing backward from the edge of the radiator 9 to the ventilation duct 6, thereby improving the heat dissipation effect of the radiator 9.

[0027] A liquid filter plate 14 is fixedly installed inside the operating compartment 1 below the top plate 2, and the vent 3 and the connecting pipe 8 are located on both sides of the filter plate. The liquid filter plate 14 filters small particulate impurities in the coolant, preventing impurities from entering the radiator 9 and clogging the water circuit, thereby improving service life and stability.

[0028] Reference Figure 1-2 The operating chamber 1 has hinged plates 15 on both sides of its top surface. A limiting block 16 extends inward from the inner sidewall of the top of the operating chamber 1. When not cutting, the hinge plates 15 hang naturally. Before cutting, the two hinge plates 15 are rotated until their bottom surfaces are in contact with the limiting block 16. At this point, the two hinge plates 15 shield the top surfaces of the operating chamber 1 on both sides, preventing the electric spark light from directly shining into the worker's eyes and improving safety. Furthermore, shielding the top surfaces of the operating chamber 1 reduces the exposed area of ​​the top surface, facilitating the intake of exhaust gases generated by electric spark cutting to the filter plate and improving the filtration effect.

[0029] The hinge plate 15 is L-shaped. The L-shaped design is to match the cutting component located in the middle of the operating chamber 1, leaving space for the cutting component while further reducing the exposed area of ​​the top surface of the operating chamber 1, thereby further improving the exhaust gas filtration effect.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
