Description

Technical Field

[0001] This utility model relates to the technical field of wire EDM machine tools, specifically a cooling device for wire EDM machine tools. Background Technology

[0002] The cooling device of the wire EDM machine tool is an important part of the wire EDM process. During wire EDM, high-frequency discharge is generated between the electrode wire and the workpiece, releasing a large amount of heat. The cooling device can effectively remove the heat and prevent the workpiece and electrode wire from deforming or being damaged due to excessive temperature.

[0003] A search revealed a Chinese patent with publication number CN215238393U, which discloses a cooling device for a wire EDM machine. This cooling device operates using a fan, which blows the coolant flowing out of the cooling pipes towards the drain outlet. This prevents the coolant from flowing around and causing difficulties in cleaning the equipment. In addition, the high-speed airflow from the fan assists in cleaning and dissipating heat from the workpiece. By loosening the fixing bolts on the top of the sliding seat, the sliding seat can drive the fan to slide inside the groove, allowing the fan's position to be changed. This avoids dead zones during fan use and improves the flexibility of the equipment.

[0004] However, in the prior art, when processing thick workpieces, the discharge energy between the electrode wire and the workpiece is concentrated in the processing area, resulting in excessively high local temperatures. At the same time, impurities such as metal shavings and oil stains generated during processing affect the heat exchange efficiency of the coolant. In order to solve the problem of poor heat dissipation in the prior art, this application proposes to improve the heat dissipation effect by setting up auxiliary heat dissipation components to spray and clean the surface of the workpiece, thereby removing impurities such as metal shavings and oil stains from the surface of the workpiece. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with a main nozzle, an auxiliary nozzle, a connecting plate, a drive rod, a fixed shaft, and other components.

Detailed Implementation

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 The present invention relates to a cooling device for a wire cutting machine tool, comprising a base 1, a support column 2 on the base 1, a wire cutting device 3 on the support column 2, a main nozzle 4 on the wire cutting device 3, a support frame 5 between the support column 2 and the wire cutting device 3, a slide plate 6 on the support frame 5, a connecting plate 9 rotatably mounted on the slide plate 6, an auxiliary nozzle 8 at one end of the connecting plate 9, and a circulation assembly between the connecting plate 9 and the slide plate 6.

[0024] Combination Figure 2 , Figure 3As shown, the circulation assembly includes a fixed shaft 12. One end of the connecting plate 9 is rotatably mounted on the slide plate 6 via the fixed shaft 12. The connecting plate 9 is provided with a sliding groove 14, and the slide plate 6 is provided with a guide groove 15. A drive rod 13 is provided between the sliding groove 14 and the guide groove 15. The guide groove 15 restricts the movement direction of the drive rod 13. While the drive rod 13 moves, it moves along with it in the sliding groove 14 and pushes the connecting plate 9 to rotate around the fixed shaft 12. By changing the movement direction of the drive rod 13, the rotation direction of the connecting plate 9 is adjusted.

[0025] like Figure 3 , Figure 4 As shown, the circulation assembly also includes a drive plate 16, which is slidably mounted on the slide plate 6. One end of the drive rod 13 is mounted on the drive plate 16. The drive plate 16 is provided with two rows of opposing teeth, and an incomplete gear 17 is provided between the two rows of teeth. The incomplete gear 17 is rotatably mounted on the slide plate 6 and meshes with the teeth. By driving the incomplete gear 17 to rotate, the incomplete gear 17 pushes the drive plate 16 to move through the meshing teeth. By the incomplete gear 17 meshing with the two rows of teeth in turn, the reciprocating movement of the drive plate 16 is realized.

[0026] In a preferred embodiment, the drive plate 16 is a rectangular frame, and an incomplete gear 17 is disposed inside the drive plate 16. Two rows of teeth are symmetrically disposed on the inner wall of the drive plate 16. The auxiliary nozzle 8 is rotatably connected to the slide plate 6 via the mounting block 10. A fixing rod 11 is rotatably mounted on the mounting block 10 and is threadedly connected to the slide plate 6. By driving the fixing rod 11 to rotate, the fixing restriction between the mounting block 10 and the connecting plate 9 is released. Subsequently, the auxiliary nozzle 8 and the mounting block 10 can be driven to rotate, thereby adjusting the spray angle of the auxiliary nozzle 8. The direction of the drive rod 11 to rotate is used to fix the position of the mounting block 10 and the auxiliary nozzle 8.

[0027] See Figure 3 As shown, a limit plate 18 is provided on the slide plate 6. The limit plate 18 is slidably set with the drive plate 16. A servo motor 19 is provided on the limit plate 18. The output end of the servo motor 19 is connected to the incomplete gear 17. By controlling the operation of the servo motor 19, the servo motor 19 drives the incomplete gear 17 to rotate, thereby realizing the uniform reciprocating movement of the drive plate 16 and reducing the labor intensity of the workers.

[0028] Looking back Figure 1 , Figure 2As shown, the support frame 5 is symmetrically arranged. A fastening rod 7 is provided between the slide plate 6 and the support frame 5. The fastening rod 7 is threadedly connected to the support frame 5. One end of the fastening rod 7 contacts the slide plate 6. By driving the fastening rod 7 to rotate, the fixation restriction on the slide plate 6 is released. Subsequently, the height of the slide plate 6 can be adjusted, and the auxiliary nozzle 8 can be moved accordingly. When the auxiliary nozzle 8 reaches the preset height, it reverses and drives the fastening rod 7 to rotate, thus restricting the position of the slide plate 6. This allows it to be used for workpieces of different thicknesses.

[0029] The implementation principle is as follows: During the processing, the main nozzle 4 cools the electrode wire and the workpiece processing area. At the same time, the servo motor 19 drives the incomplete gear 17 to rotate. The incomplete gear 17 pushes the drive plate 16 to move by meshing with the teeth. The drive plate 16 drives the drive rod 13 to move accordingly. The drive rod 13 pushes the connecting plate 9 to rotate around the fixed shaft 12. One end of the connecting plate 9 drives the auxiliary nozzle 8 to perform a fan-shaped motion. At the same time, the auxiliary nozzle 8 sprays coolant onto the workpiece surface for cleaning and cooling, thereby improving the cooling effect on the workpiece.

Various modifications and variations can be made to this utility model by those skilled in the art.
