Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a self-cleaning wire cutting machine. Background Technology

[0002] Wire EDM is a machine tool that uses the principle of electric spark discharge to cut and process metal materials, and it is widely used in mold manufacturing, aerospace, automobile manufacturing and other fields.

[0003] A search revealed that Chinese patent CN221289796U discloses a wire cutting machine that uses an exhaust mechanism to draw exhaust gas into a water storage chamber. The water in the storage chamber filters out pollutants and absorbs odors from the exhaust gas, while also cooling it to prevent overheating and affecting the purification effect of the filtration mechanism. The purified exhaust gas then enters the interior of the filtration chamber through a vent, where it undergoes secondary purification by the filtration mechanism. A drive mechanism then rotates the exhaust mechanism, accelerating the discharge of the purified exhaust gas to the outside environment. This dual purification of the exhaust gas enhances the environmental friendliness of the wire cutting machine.

[0004] However, in the existing technology, wire cutting machines generate various debris and contaminants during operation, causing impurities to scatter in the processing area, affecting processing accuracy and equipment lifespan, requiring manual cleaning by workers. In order to solve the problem of cleaning debris and contaminants in the existing technology, this application proposes to automatically clean the processing area and workpiece by setting up a freely movable cleaning component, thereby avoiding manual cleaning by workers and reducing the labor intensity of workers. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has the shortcomings and defects of requiring manual cleaning of debris and contaminants, which makes cleaning troublesome and labor-intensive.

[0006] The self-cleaning wire cutting machine disclosed in this utility model includes a base, a cutting body and a shell on the base, a sliding plate on the inner side of the shell, a driving component between the sliding plate and the shell, a vertical plate on the base, an adjusting component between the vertical plate and the sliding plate, a mounting plate on one side of the vertical plate, an ultrasonic vibrator on the mounting plate, and a brush plate on the lower end face of the mounting plate.

[0007] Furthermore, a high-pressure nozzle is provided on the side of the vertical plate away from the brush plate, and the high-pressure nozzle is mounted on the vertical plate by a fixing plate.

[0008] Furthermore, the adjustment assembly includes a screw, which is rotatably mounted on the slide plate. The screw is threadedly connected to the vertical plate, and limiters are provided at both ends of the vertical plate and the slide plate.

[0009] Furthermore, the limiting component includes a limiting shaft, which is fixedly installed on the slide plate. A sliding groove is provided on the vertical plate, and the limiting shaft is slidably connected to the sliding groove.

[0010] Furthermore, a connecting shaft is provided between the mounting plate and the vertical plate. The connecting shaft is mounted on the vertical plate. The mounting plate is provided with a mounting hole. The connecting shaft passes through the mounting hole. A limit cap is threaded onto the connecting shaft. The length of the mounting hole is greater than the diameter of the connecting shaft.

[0011] Furthermore, a locking block is provided at the upper end of the brush plate, and a locking groove is provided on the mounting plate at the corresponding position of the locking block, and the locking block engages with the locking groove.

[0012] Furthermore, the drive assembly includes a lead screw, which is rotatably mounted on the housing and threadedly connected to the slide plate. A servo motor is provided at the power end of the lead screw, and the servo motor is mounted on the housing.

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

[0014] 1. This utility model is equipped with components such as a sliding plate, a vertical plate, an ultrasonic vibrator, and a brush plate. During the working process, after the processing is completed, the sliding plate is controlled to move horizontally by the drive component. The vertical plate component, the brush plate component, and the ultrasonic vibrator component work together to automatically clean the inside of the device and the surface of the workpiece, avoiding the trouble of manual cleaning by the workers and thus reducing the labor intensity of the workers.

[0015] 2. This utility model is equipped with components such as a high-pressure nozzle, a fixed plate, a limiting shaft, and a screw. During operation, the high-pressure nozzle and the fixed plate work together to mount the high-pressure nozzle on the sliding plate and achieve synchronous movement with the sliding plate. The high-pressure air jet can first blow most of the loose debris away from the working area, and the brush plate then performs fine cleaning to ensure that residual debris is completely removed, thereby improving the cleaning effect. By adjusting the rotation of the screw, the height of the brush plate can be adjusted to facilitate cleaning of workpieces of different heights and increase the applicability of the device.

[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 self-cleaning wire cutting machine of this utility model includes a base 1, a cutting body 2 and a shell 3 on the base 1, a sliding plate 4 on the inner side of the shell 3, a filter screen 19 on the shell 3 below the sliding plate 4, a liquid outlet pipe 20 on one side of the shell 3, a driving component between the sliding plate 4 and the shell 3, a vertical plate 5 on the base 1, an adjustment component between the vertical plate 5 and the sliding plate 4, a mounting plate 8 on one side of the vertical plate 5, an ultrasonic vibrator 14 on the mounting plate 8, and a brush plate 11 on the lower end face of the mounting plate 8. The ultrasonic vibrator 14 and the brush plate 11 work together to help break the adhesion between the chips and the workpiece surface, thereby improving the cleaning effect.

[0024] The cutting body 2 is a common wire EDM machine. The workpiece is connected to the positive terminal of the pulse power supply, and a metal wire such as molybdenum wire or copper wire is used as the cutting electrode wire. The electrode wire is connected to the negative terminal of the high-frequency pulse power supply as the tool electrode. Under the action of the electric field, an instantaneous high-temperature heat source is formed between the electrodes, causing local metal melting and vaporization. The vaporized working fluid and workpiece material vapor expand rapidly and instantaneously. Under the combined action of thermal expansion and working fluid pressure, the melted and vaporized workpiece material is thrown out of the discharge channel, completing one spark discharge process. The above discharge process is repeated continuously. The cutting trajectory of the metal wire is controlled by CNC programming, thereby cutting the workpiece into shape.

[0025] like Figure 1 As shown, a high-pressure nozzle 7 is provided on the side of the vertical plate 5 away from the brush plate 11. The high-pressure nozzle 7 is connected to an external air tank and is installed on the vertical plate 5 through a fixing plate 6. The high-pressure nozzle 7 can blow most of the loose debris away from the working area, achieving preliminary cleaning and facilitating fine cleaning that needs to be performed by the brush plate 11.

[0026] like Figure 2 As shown, the adjustment assembly includes a screw 15, which is rotatably mounted on the slide plate 4. The screw 15 is threadedly connected to the vertical plate 5. Limiting components are provided at both ends of the vertical plate 5 and the slide plate 4. By driving the screw 15 to rotate, the screw 15 drives the vertical plate 5 to move on the slide plate 4. The slide plate 4 drives the brush plate 11 and the high-pressure nozzle 7 to move accordingly, thereby adjusting the height of the brush plate 11. This facilitates cleaning of workpieces of different heights and improves the applicability of the device.

[0027] Combination Figure 2 , Figure 3 As shown, the limiting component includes a limiting shaft 16, which is fixedly installed on the slide plate 4. A slide groove 17 is provided on the vertical plate 5. The limiting shaft 16 is slidably connected to the slide groove 17. While the vertical plate 5 moves, the limiting shaft 16 restricts both ends, thereby improving the stability of the vertical plate 5 during movement.

[0028] See Figure 2 , Figure 4 As shown, a connecting shaft 9 is provided between the mounting plate 8 and the vertical plate 5. The connecting shaft 9 is mounted on the vertical plate 5. The mounting plate 8 is provided with a mounting hole 10. The connecting shaft 9 passes through the mounting hole 10. A limit cap is threaded onto the connecting shaft 9. The length of the mounting hole 10 is greater than the diameter of the connecting shaft 9. Rubber pads are provided on both sides of the mounting plate 8, and the rubber pads are fitted onto the connecting shaft 9.

[0029] In a preferred embodiment, a locking block 12 is provided on the upper end of the brush plate 11, and a locking groove 13 is provided on the mounting plate 8 at the corresponding position of the locking block 12. The locking block 12 and the locking groove 13 are engaged. Through the mutual cooperation between the locking block 12 and the locking groove 13, the brush plate 11 and the mounting plate 8 can be quickly connected, thereby improving the convenience of installation.

[0030] Looking back Figure 1 As shown, the drive assembly includes a lead screw 18, which is rotatably mounted on the housing 3. The lead screw 18 is threadedly connected to the slide plate 4. A servo motor is provided at the power end of the lead screw 18. The servo motor is mounted on the housing 3. The lead screw 18 is driven to rotate by the servo motor, thereby driving the slide plate 4 to move. The direction of movement of the slide plate 4 is adjusted by controlling the rotation direction of the servo motor.

[0031] The implementation principle is as follows: After the workpiece is processed, the lead screw 18 is driven to rotate by the servo motor. The lead screw 18 drives the slide plate 4 to move. The slide plate 4 drives the vertical plate 5 to move. The vertical plate 5 drives the brush plate 11 and the high-pressure nozzle 7 to move synchronously. The high-pressure nozzle 7 first blows most of the loose debris away from the working area. Then the brush plate 11 performs fine cleaning to ensure that the residual debris is completely removed. At the same time, the ultrasonic vibrator 14 assists the brush plate 11 in cleaning to improve the cleaning effect.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
