Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, in particular to a smoke removal device for metal product processing. Background Art

[0002] During the metal welding process, the welding rod will produce smoke due to high-temperature combustion, and the insoluble substances in the smoke are easy to cause pneumoconiosis. Long-term inhalation will cause fibrotic lesions in the lung tissue of workers. Therefore, the smoke needs to be adsorbed and filtered during the welding process. Existing welding tables usually have fans to generate negative pressure, suck the smoke into the filter, and filter the smoke through the filter to achieve the effect of dust reduction.

[0003] Since the welding platform is relatively large compared to the welding site, during the actual welding process, if the large-area welding platform is constantly adsorbing smoke, then in order to ensure the suction strength, the vacuum pump needs a larger power and needs to continuously perform suction work. This causes the welding platform to not only easily adsorb the smoke generated by welding, but also more easily absorb impurities in the air into the filter, making the filter component more easily clogged. In the process of adsorption and drainage, the welding platform is more likely to cause external dust and impurities to be drained to the operator's position, and then more easily absorbed by the operator, so improvement is needed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a smoke removal device for metal product processing, comprising a spot welding component, drainage devices are symmetrically arranged on the front and rear sides of the spot welding component, and a workbench is arranged below the spot welding component;

[0005] The spot welding component includes a hollow spacer, and plug interfaces are symmetrically provided on both sides of the outer surface of the hollow spacer, and the plug interfaces extend to the inner cavity of the hollow spacer, and adsorption elbows are evenly arranged at the bottom of the inner cavity of the hollow spacer, and a welding rod is slidably connected to the axis of the inner wall of the hollow spacer, and a tension cover plate is fixedly connected to the top of the inner cavity of the hollow spacer, and tension rods are evenly arranged on the lower surface of the tension cover plate, and a sliding clustering ring is fixedly connected to the bottom end of the tension rod, and the sliding clustering ring can use the tension rod as a force-transmitting component to pressurize or pull the fixed tension cover plate, and a detection device is provided in the middle of the inner wall of the hollow spacer. Since the top end of the welding rod extends to the outside of the hollow spacer, the welding rod can be pushed downward by pressing down the top of the welding rod to achieve single spot welding;

[0006] The drainage equipment includes an exhaust bottom box, both ends of which are fixedly connected with hollow conduits, the top of the hollow conduit is fixedly connected with a drainage box shell, adsorption inner blocks are symmetrically arranged on both sides of the inner wall of the drainage box shell, and the top of the inner cavity of the drainage box shell is fixedly connected with a compression connecting pipe through a through opening, the part where the compression connecting pipe is inserted into one side of the drainage box shell is a fixed bent pipe structure, but the part directly connected to the hollow partition tube is a compressible and deformable hose structure.

[0007] Furthermore, the workbench includes a base frame, a modified pallet is slidably connected to the axis at the top of the inner wall of the base frame, a processing plate is arranged on the upper surface of the modified pallet, elastic support columns are evenly arranged on the lower surface of the modified pallet, power supply boxes are symmetrically arranged on the front and rear sides of the outer surface of the base frame, and the top of the power supply box is fixedly connected to a built-in plug through a sticking plate.

[0008] Furthermore, magnetic plates are symmetrically arranged on the left and right sides of the outer surface of the base frame, and a multi-section sleeve rod is slidably connected to one side of the outer surface of the magnetic plate close to the hollow spacer. The multi-section sleeve rod has a retractable structure similar to a folding cup, and one side of the multi-section sleeve rod that is in contact with the magnetic plate is adsorbed on the outer surface of the magnetic plate by magnetic force, so the multi-section sleeve rod can be in contact with the outer surface of the magnetic plate for free sliding movement, and the end of the multi-section sleeve rod away from the magnetic plate is fixedly connected to the outer surface of the hollow spacer through a socket.

[0009] Furthermore, one end of the compression connection pipe away from the drainage box shell is connected to the inner cavity of the hollow spacer through the plug interface, the number of the drainage devices is two, the lower surface of the drainage box shell is fixedly connected to one side of the upper surface of the bottom frame, and the outer surface of the vacuum bottom box is fixedly connected to one side of the outer surface of the bottom frame. A spring washer is sleeved on the upper part of the outer surface of the welding rod, the top end of the welding rod extends to the outside of the tension cover plate, and the top end of the welding rod is slidably connected to the axis of the inner cavity of the tension cover plate, and the outer surface of the sliding cluster ring is slidably connected to the inner cavity of the hollow spacer.

[0010] Further, the modified support plate includes an arched slide plate, the top of the inner wall of the arched slide plate is evenly provided with a plug sleeve, the front and rear sides of the inner cavity of the arched slide plate are symmetrically provided with a limit plug plate, and the outer surface of the limit plug plate is symmetrically provided with a compression spring belt on both sides away from the plug sleeve. The outer surface of the arched slide plate is slidably connected to the inner wall of the bottom frame, the side of the outer surface of the limit plug plate close to the plug sleeve is slidably connected to the inner wall of the arched slide plate, the end of the limit plug plate away from the plug sleeve is plugged into the inner wall of the built-in plug through a through slot, the top of the elastic support column is fixedly connected to the inner wall of the arched slide plate through the plug sleeve, the modified support plate is limited to a fixed height of the inner wall of the bottom frame by the limit plug plates on both sides, and when the arched slide plate is subjected to a large downward pressure, the end parts of the limit plug plates on both sides will slide out from the socket of the inner cavity of the bottom frame, thereby losing the limiting effect on the modified support plate.

[0011] Further, the detection device comprises an inner ring sleeve, the top of the inner cavity of the inner ring sleeve is slidably connected with an adsorption slider, the bottom of the inner cavity of the adsorption slider is evenly provided with detection suction rods, the bottom end of the detection suction rod is fixedly connected with a closed bottom cover, and the lower surface of the adsorption slider is fixedly connected with a spring sleeve. The outer surface of the inner ring sleeve is fixedly connected to the middle of the inner wall of the hollow spacer, the bottom end of the spring washer is fixedly connected to the upper surface of the adsorption slider, the bottom end of the spring sleeve is fixedly connected to the bottom of the inner cavity of the inner ring sleeve, and the outer surface of the welding rod is slidably connected to the axis of the inner wall of the inner ring sleeve.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device performs spot welding on the processing plate below through a welding rod that can move relatively freely. Since toxic smoke and gas will be generated during spot welding, and the actual scope of the overall spot welding work is also relatively large, the hollow partition is improved and directly connected to the exhaust bottom box through the compression connecting pipes on both sides. The adsorption elbow surrounding the bottom of the hollow partition is used to adsorb the toxic gas generated by each spot welding. Therefore, without the need for large-scale modification of the workbench, the fume cleaning work of the spot welding work can be achieved, and the adsorption position each time is relatively accurate, which is more advantageous.

[0014] 2. The adsorption elbow of the device points to the range of spot welding by the welding rod, so there will be no large-scale adsorption work in the surrounding area, which will cause the exhaust bottom box to absorb too many air impurities and easily become blocked. Since spot welding is prone to produce larger particulate impurities, if these impurities are adsorbed by the adsorption elbow, the adsorption elbow may be blocked. At this time, the pressure in the inner cavity of the hollow spacer tube drops suddenly, thereby pulling the tension cover on the top through the tension rod. The tension cover reminds the operator to clear the adsorption elbow in time according to the sudden increase in tension, so as to avoid the diffusion of smoke generated by spot welding.

[0015] 3. When spot welding is performed, the welding rod will exert a certain amount of pressure on the processing plate. However, when the operator pushes down the welding rod and causes the pressure on the processing plate to be too great, the processing plate may be welded through. Therefore, the modified pallet is improved so that the arched slide has a certain load-bearing capacity. When the pressure is too great, the processing plate can be transported to the side away from the bottom end of the welding rod and the power supply of the welding rod can be disconnected, thereby playing an effective protective role and avoiding the above problems.

[0016] 4. Every time the welding rod slides down for spot welding, the detection suction rod inside the inner ring sleeve will also slide out, absorb the surrounding air through the exposed mesh holes, perform gas detection, and judge the air pollution level at the current position, thereby judging whether the smoke removal effect of the device is qualified. In order to avoid the detection suction rod performing meaningless detection work when the welding rod is not working, the detection suction rod will automatically shrink inside the inner ring sleeve and be isolated from the outside world by the closed bottom cover, thereby preventing the detection suction rod from working, achieving a certain automation effect.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a smoke removal device for metal product processing, comprising a spot welding component 1, a drainage device 3 is symmetrically arranged on the front and rear sides of the spot welding component 1, and a workbench 2 is arranged below the spot welding component 1;

[0027] The spot welding component 1 includes a hollow spacer 11, and plug-in ports 12 are symmetrically provided on both sides of the outer surface of the hollow spacer 11, and the plug-in ports 12 extend to the inner cavity of the hollow spacer 11, and adsorption elbows 13 are evenly arranged at the bottom of the inner cavity of the hollow spacer 11. A welding rod 14 is slidably connected to the axis of the inner wall of the hollow spacer 11, and a tension cover plate 18 is fixedly connected to the top of the inner cavity of the hollow spacer 11. Tension rods 17 are evenly arranged on the lower surface of the tension cover plate 18, and a sliding clustering ring 16 is fixedly connected to the bottom end of the tension rod 17. The sliding clustering ring 16 can use the tension rod 17 as a force-transmitting component to pressurize or pull the fixed tension cover plate 18. A detection device 4 is arranged in the middle of the inner wall of the hollow spacer 11. Since the top end of the welding rod 14 extends to the outside of the hollow spacer 11, the welding rod 14 can be pushed downward by pressing down the top of the welding rod 14 to achieve a single spot welding operation;

[0028] The drainage device 3 includes an exhaust bottom box 31, both ends of which are fixedly connected with hollow conduits 32, the top of the hollow conduit 32 is fixedly connected with a drainage box shell 33, adsorption inner blocks 34 are symmetrically arranged on both sides of the inner wall of the drainage box shell 33, and the top of the inner cavity of the drainage box shell 33 is fixedly connected with a compression connecting pipe 35 through a through opening, and the part where the compression connecting pipe 35 is inserted into one side of the drainage box shell 33 is a fixed bent pipe structure, but the part directly connected to the hollow partition 11 is a compressible and deformable hose structure.

[0029] The workbench 2 includes a base frame 21, a modified pallet 5 is slidably connected to the axis at the top of the inner wall of the base frame 21, a processing plate 24 is arranged on the upper surface of the modified pallet 5, and elastic support columns 25 are evenly arranged on the lower surface of the modified pallet 5. Power supply boxes 26 are symmetrically arranged on the front and rear sides of the outer surface of the base frame 21, and the top of the power supply box 26 is fixedly connected with a built-in plug 27 through a sticking plate.

[0030] Magnetic plates 22 are symmetrically arranged on the left and right sides of the outer surface of the bottom frame 21. The outer surface of the magnetic plate 22 is slidably connected to a multi-section sleeve rod 23 on one side close to the hollow partition tube 11. The multi-section sleeve rod 23 has a retractable structure similar to a folding cup, and one side of the multi-section sleeve rod 23 that is in contact with the magnetic plate 22 is adsorbed on the outer surface of the magnetic plate 22 by magnetic force, so the multi-section sleeve rod 23 can be in contact with the outer surface of the magnetic plate 22 for free sliding movement, and the end of the multi-section sleeve rod 23 away from the magnetic plate 22 is fixedly connected to the outer surface of the hollow partition tube 11 through a socket.

[0031] The end of the compression connecting tube 35 away from the drainage box shell 33 is connected to the inner cavity of the hollow partition 11 through the plug interface 12. The number of drainage devices 3 is two. The lower surface of the drainage box shell 33 is fixedly connected to one side of the upper surface of the bottom frame 21, and the outer surface of the exhaust bottom box 31 is fixedly connected to one side of the outer surface of the bottom frame 21. A spring washer 15 is sleeved on the upper part of the outer surface of the welding rod 14, and the top end of the welding rod 14 extends to the outside of the tension cover plate 18, and the top end of the welding rod 14 is slidably connected to the axis of the inner cavity of the tension cover plate 18, and the outer surface of the sliding cluster ring 16 is slidably connected to the inner cavity of the hollow partition 11.

[0032] The device is easy to use. After placing the processing plate 24 that needs spot welding on the modified support plate 5 on the inner wall of the base frame 21, the hollow spacer 11 can be manually moved to move the welding rod 14, and then the hollow spacer 11 can be fixed, and the welding rod 14 can be pressed downward to spot weld the upper surface of the processing plate 24 through the bottom end of the welding rod 14.

[0033] During the movement of the hollow spacer 11, the compression connecting tubes 35 on the front and rear sides can bend and deform as the hollow spacer 11 moves, and the multi-section sleeve rods 23 on both sides can stretch and shrink and slide along the outer surface of the magnetic plate 22, so the hollow spacer 11 has a relatively high degree of freedom in movement.

[0034] When spot welding is performed, the vacuum bottom boxes 31 on both sides continuously evacuate and reduce the pressure inside the drainage box shell 33 through the hollow conduit 32. At this time, the drainage box shell 33 will evacuate the inner cavity of the hollow partition tube 11 through the compression connecting tube 35, so that each adsorption elbow 13 has the function of absorbing gas, and the adsorption elbow 13 always surrounds the welding rod 14, so the adsorption elbow 13 can always absorb the toxic smoke generated by the spot welding of the welding rod 14 into the interior of the drainage box shell 33, and solve the pollution problem caused by welding through the purification work of the adsorption inner block 34.

[0035] Since the compression connecting tube 35 sucks air into the inner cavity of the hollow spacer 11 through the plug interface 12, the sliding clustering ring 16 above will also be affected by the decompression effect. When the adsorption elbow 13 is blocked due to the adsorption of excessive impurities, when the extraction force of the compression connecting tube 35 is fixed, the downward pulling force on the sliding clustering ring 16 will increase, thereby pulling the tension cover plate 18 on the top through the tension rod 17. The tension cover plate 18 reminds the operator to clear the adsorption elbow 13 in time according to the sudden increase in tension.

[0036] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of embodiment 1, the modified support plate 5 includes an arched slide plate 51, a plug-in sleeve 52 is evenly arranged on the top of the inner wall of the arched slide plate 51, and a limiting plug plate 53 is symmetrically arranged on the front and rear sides of the inner cavity of the arched slide plate 51, and compression spring belts 54 are symmetrically arranged on both sides of the outer surface of the limiting plug plate 53 away from the plug-in sleeve 52. The outer surface of the arched slide plate 51 is slidably connected to the inner wall of the base frame 21, and the outer surface of the limiting plug plate 53 is slidably connected to the inner wall of the arched slide plate 51 on one side close to the plug sleeve 52. The end of the limiting plug plate 53 away from the plug sleeve 52 is plugged into the inner wall of the built-in plug 27 through a through slot, and the top of the elastic support column 25 is fixedly connected to the inner wall of the arched slide plate 51 through the plug sleeve 52. The modified support plate 5 is limited to a fixed height of the inner wall of the base frame 21 by the limiting plug plates 53 on both sides. When the arched slide plate 51 is subjected to a large downward pressure, the end parts of the limiting plug plates 53 on both sides will slide out of the socket in the inner cavity of the base frame 21, thereby losing the limiting effect on the modified support plate 5.

[0037] The detection device 4 includes an inner ring sleeve 41, the top of the inner cavity of the inner ring sleeve 41 is slidably connected to an adsorption slider 45, the bottom of the inner cavity of the adsorption slider 45 is evenly provided with detection suction rods 44, the bottom end of the detection suction rod 44 is fixedly connected to a closed bottom cover 42, and the lower surface of the adsorption slider 45 is fixedly connected to a spring sleeve 43. The outer surface of the inner ring sleeve 41 is fixedly connected to the middle of the inner wall of the hollow spacer 11, the bottom end of the spring washer 15 is fixedly connected to the upper surface of the adsorption slider 45, the bottom end of the spring sleeve 43 is fixedly connected to the bottom of the inner cavity of the inner ring sleeve 41, and the outer surface of the welding rod 14 is slidably connected to the axis of the inner wall of the inner ring sleeve 41.

[0038] The limit plugs 53 on both sides of the arched slide 51 are squeezed toward the side sockets of the arched slide 51 through the compression spring belts 54. When the pressure on the processing plate 24 above the arched slide 51 is too great, the limit plugs 53 on both sides will be squeezed out from the inner wall of the base frame 21, thereby losing the effect of clamping the arched slide 51. At the same time, the built-in plug 27 interrupts the power supply to the limit plugs 53, so the device will also be powered off, thereby stopping the welding rod 14 from welding.

[0039] When the welding rod 14 is pressed down, under the thrust of the spring washer 15, the adsorption slider 45 located in the middle is also pushed downward. At this time, the closed bottom cover 42 and the detection suction rod 44 slide downward from the inner wall of the inner ring sleeve 41, and the spring sleeve 43 is also compressed. The exposed detection suction rod 44 will perform air quality extraction detection on the area produced by the spot welding of the welding rod 14 through the space at the axis of the hollow spacer 11, and then feed back to the adsorption slider 45, so as to judge the air quality in the area. When the welding rod 14 shrinks back to its original position, the spring washer 15 and the spring sleeve 43 pull the closed bottom cover 42, the detection suction rod 44 and the adsorption slider 45 back to the initial position, and then the closed bottom cover 42 blocks the notch at the bottom of the inner ring sleeve 41.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
