Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a fume treatment structure of an electric spark wire cutting machine tool. Background Art

[0002] Wire EDM is a machine tool that uses the principle of electric spark for cutting. It is mainly composed of a control system, a mechanical structure, a power supply system, a servo system, a cutting wire and auxiliary equipment. During the wire EDM process, the workpiece and the cutting wire are used as two electrodes with different polarities. The cutting wire passes through the workpiece. Under the action of a high-frequency pulse power supply, electric spark discharge is generated between the two electrodes. The discharge channel instantly generates high temperature, causing the surface of the workpiece to melt or even vaporize. Through the movement of the XY axis and the UV axis, the cutting wire moves along a predetermined trajectory to achieve cutting of the workpiece. Wire EDM usually produces some smoke and exhaust gas during operation. These smoke and exhaust gas mainly come from the gas release during the corrosion and dissolution of the workpiece and electrode materials, as well as the gas generated by the evaporation and injection of the working fluid. Since the exhaust gas contains fine particles, in order to ensure the safety of the working environment and the health of the operator, it is necessary to treat the exhaust gas.

[0003] In the related art, during the use of the wire-cut electric discharge machine, the exhaust gas is generally sucked out by a vacuum pump to treat the exhaust gas.

[0004] However, during the current use of wire-cut EDM machines, since the exhaust gas will diffuse everywhere, the suction end of the vacuum pump is difficult to follow the movement of the working head to suck the exhaust gas, resulting in incomplete exhaust gas treatment. Exhaust gas still diffuses outward, affecting the comprehensiveness and treatment effect of the exhaust gas treatment. Utility Model Content

[0032] Example

[0033] Reference Figure 1-Figure 5 The utility model provides a technical solution: a smoke treatment structure of an electric spark wire cutting machine, comprising an electric spark wire cutting machine body 1 and a smoke treatment mechanism, a working plate 2 is installed on the top of the electric spark wire cutting machine body 1, and a working head 3 is installed on the bottom of the working plate 2.

[0034] Reference Figure 1-Figure 5In a preferred embodiment, the smoke treatment mechanism includes a treatment box 4, which is arranged on the left side of the electric spark wire cutting machine body 1, and an air pump 5 is installed on the right side of the treatment box 4. The output end of the air pump 5 is connected to the treatment box 4, and a hose 6 is fixedly connected to the input end of the air pump 5. A suction head 7 is fixedly connected to the right side of the hose 6, and a follower frame 8 is fixedly connected to the top of the suction head 7. A clamp 9 is installed on the top and bottom of both sides of the follower frame 8. The gas separation and filtering mechanism is movably connected to the inside of the treatment box 4. Since the suction head 7 is connected to the input end of the air pump 5 through the hose 6, and the output end of the air pump 5 is connected to the treatment box 4, and the follower frame 8 and the clamp 9 are installed on the top of the suction head 7, when the treatment box 4 is used for the first time, clean water is first added to the inside of the treatment box 4 to prepare for the subsequent adsorption of dirt in the smoke, and then according to actual use needs, the suction head 7 is connected to the working plate 2 through the follower frame 8 and the clamp 9. The suction head 7 can move with the working plate 2 and the working head 3. When the working plate 2 and the working head 3 are working, the suction head 7 moves with the working head 3 to suck the flue gas during the working process, and concentrates the flue gas into the treatment box 4, so that the clean water in the treatment box 4 can adsorb the dirt in the flue gas. The gas separation and filtering mechanism includes a gas separation frame 10, a gas separation plate 11, a filter box 12 and filter cotton 13. The gas separation frame 10 is movably connected to the inside of the treatment box 4, the gas separation plate 11 is fixedly connected to the bottom of the inner side of the gas separation frame 10, the filter box 12 is fixedly connected to the top of the gas separation frame 10, and the filter cotton 13 is movably connected to the inside of the filter box 12.

A plurality of support rods 15 are provided, and the plurality of support rods 15 are distributed at equal distances. In the process of the filter box 12 cooperating with the filter cotton 13, a space can be provided for the separated smoke to enter the filter box 12 and contact the filter cotton 13.

The right side of the sliding rod 17 is fixedly connected to the left side of the chuck 9. When the chuck 9 is used in conjunction with the follower frame 8, a medium for following connection can be provided for the chuck 9 to avoid separation from the follower frame 8 during use, which makes it difficult for the suction head 7 to be connected to the working plate 2. Therefore, the connection effect between the chuck 9 and the follower frame 8 is improved.

When the sliding rod 17 is used in conjunction with the chuck 9, the chuck 9 can be magnetically positioned by the sliding rod 17 to avoid the situation that the chuck 9 is difficult to clamp and position when in use. Therefore, the clamping and positioning stability of the chuck 9 is improved, and the top of the filter box 12 is fixed. A lifting frame 21 is connected, and positioning holes 22 are provided on both sides of the lifting frame 21. Positioning columns 23 are movably connected inside the positioning holes 22. Positioning grooves 24 are provided on both sides of the inner wall of the processing box 4. The outer sides of the positioning columns 23 are located inside the positioning grooves 24. When the gas distribution frame 10 cooperates with the filter box 12 and the gas distribution plate 11 to work, a medium for positioning between the gas distribution frame 10 and the processing box 4 can be provided to the user, so as to avoid the gas distribution frame 10 being lifted or lowered due to the thrust of the smoke inside the processing box 4 during operation, thereby improving the stability of the connection between the gas distribution frame 10 and the processing box 4.

[0037] Reference Figure 5 In a preferred embodiment, connecting ports 25 connected to the positioning holes 22 are provided on both sides of the top of the lifting frame 21, and the connecting ports 25 are movably connected with connecting strips 26. The outer side of the connecting strips 26 is fixedly connected to the inner side of the positioning column 23. When the positioning column 23 is used in conjunction with the air distribution frame 10 through the positioning groove 24, the positioning column 23 and the lifting frame 21 can be movably connected to avoid the separation of the positioning column 23 from the lifting frame 21 when in use, thereby improving the connection effect between the positioning column 23 and the lifting frame 21. A spring 27 is provided inside the connecting port 25. One end of the spring 27 is fixedly connected to the inner wall of the connecting port 25, and the other end of the spring 27 is fixedly connected to the surface of the connecting strip 26. Slide sleeves 28 are provided on both sides of the surface of the lifting frame 21. The inner side of the slide sleeve 28 is fixedly connected to the outer side of the connecting strip 26. When the connecting strip 26 cooperates with the positioning column 23 to work, the connecting strip 26 can apply a thrust to the positioning column 23. At the same time, a medium is provided for the user to move the connecting strip 26 to drive the positioning column 23, so as to avoid the positioning column 23 from being separated from the positioning groove 24 and being difficult to move when in use, thereby improving the working stability and ease of use of the positioning column 23.

[0038] Specifically, the working process or working principle of the smoke treatment structure of the electric spark wire cutting machine is as follows: when in use, the filter cotton 13 is installed inside the filter box 12, and then the sliding sleeve 28 is held and moved inward. At this time, the connecting strip 26 follows the sliding sleeve 28 to move inside the connecting port 25 and drives the positioning column 23 to move. At this time, the spring 27 is affected by the movement of the connecting strip 26 and contracts. Then, the lifting frame 21 is held by the sliding sleeve 28 to drive the filter box 12 and the gas distribution frame 10 to move, and the gas distribution frame 10 is placed in the processing box 4. The gas distribution plate 11 and the filter box 12 are installed. At this time, the sliding sleeve 28 and the spring 27 are released. The connecting strip 26, the sliding sleeve 28 and the positioning column 23 apply thrust, so that the positioning column 23 enters the positioning groove 24, and the lifting frame 21 is used to position the gas distribution frame 10 and the processing box 4. At the same time, the sliding sleeve 28 follows the connecting strip 26 to move and reset, and then add clean water to the processing box 4, and make the clean water level higher than the filter box 12. Then, the hand-held follower frame 8 drives the suction head 7 to move, and the working plate 2 is located inside the clamp 9, and then the clamp 9 is held to clamp the working plate 2. At this time, the slide rod 17 follows the clamp 9 to move inside the sliding port 16, and the clamp 9 and the following frame 8 are movably connected. At the same time, the slider 19 follows the slide bar 17 to move inside the magnetic groove 18, and performs magnetic attraction positioning work between the moved chuck 9 and the follower frame 8 through the magnetic strip 20, so that the chuck 9 cooperates with the follower frame 8 to clamp the suction head 7 and install it on the surface of the working plate 2, and then connects the vacuum pump 5 to the external power supply through the wire to make the vacuum pump 5 work. During the working process of the working plate 2 and the working head 3, the suction head 7 cooperates with the chuck 9 through the follower frame 8 to follow the movement of the working plate 2 and the working head 3. At this time, the vacuum pump 5 gives suction to the suction head 7 through the hose 6, so that the suction head 7 can suck the smoke generated during the working process of the working head 3. The vacuum pump 5 With the help of the suction head 7, smoke is sucked into the treatment box 4 and bubbles are formed in the clean water inside the treatment box 4. At this time, the air separator 11 performs the separation work on the smoke inside the air intake treatment box 4 through the through holes on the surface, and the smoke bubbles are separated, so that the bubbles become smaller and fully contact with the clean water, which is convenient for the clean water to adsorb the dirt particles in the smoke. As the smoke bubbles rise, they pass through the air inlet 14 into the filter box 12, and the filter cotton 13 soaked in the filter box 12 performs secondary barrier filtration on the dirt particles in the bubbles to ensure the filtering effect of the smoke dirt particles. The treated smoke is discharged through the through holes on the side of the treatment box 4.

[0039] It should be noted that the vacuum pump 5 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
