Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe processing, in particular to a stainless steel pipe cutting device. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instrumentation, etc. However, most of the existing stainless steel pipe cutting is done by mechanical cutting or laser cutting. Laser cutting replaces the traditional mechanical knife with an invisible beam, which has the characteristics of high precision, fast cutting, no limitation on cutting pattern, automatic typesetting to save materials, smooth incision, low processing cost, etc., and is gradually improving or replacing the traditional stainless steel pipe cutting process equipment;

[0003] Among them, when laser cutting stainless steel pipes, the laser cutting machine is started after clamping the stainless steel pipes to perform laser cutting on the stainless steel pipes. However, smoke will appear in the laser cutting process, and most of the smoke generated is unguided, but the smoke is directly dispersed at will. At that time, the smoke will contain tiny particles (such as metal particles, metal oxides, etc.) and irritating gases (such as ozone, nitrogen oxides, etc.), which will not only easily cause the surface of the laser cutting equipment to stick to debris and form an oxide layer, but also the operator may easily inhale these substances by mistake, causing symptoms such as coughing, wheezing, and sore throat. Long-term exposure to this environment will lead to an increase in the incidence of respiratory diseases such as chronic bronchitis and emphysema, which will not only affect the effect of subsequent laser cutting, but also affect the personal safety of the staff.

[0032] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the existing laser cutting of stainless steel pipes, the laser cutting machine is started after the stainless steel pipe is clamped to perform laser cutting on the stainless steel pipe. However, smoke will appear in the laser cutting process, and most of the smoke generated is unguided, but the smoke is directly dispersed randomly. Because the smoke contains tiny particles (such as metal particles, metal oxides, etc.) and irritating gases (such as ozone, nitrogen oxides, etc.), it is not only easy to cause the surface of the laser cutting equipment to stick to debris, but also the operator is easy to accidentally inhale these substances, causing symptoms such as coughing, wheezing, and sore throat. Long-term exposure to this environment will lead to an increase in the incidence of respiratory diseases such as chronic bronchitis and emphysema, which will not only affect the effect of subsequent laser cutting, but also affect the personal safety of the staff. For the embodiments of the present invention, please refer to Figures 1 to 12 A stainless steel pipe cutting device comprises a box body 1, a discharge port 2 for preventing stainless steel pipes from being discharged is provided inside the box body 1, a laser device 3 for laser welding is detachably installed inside the box body 1, a reciprocating guide structure 400 for guiding smoke is provided inside the box body 1, a filter structure 500 for filtering smoke is provided on a side of the reciprocating guide structure 400 away from the box body 1, and a swing structure 600 for wiping the laser device 3 is provided in the middle of the reciprocating guide structure 400;

[0034] During the laser welding process, the reciprocating guide structure 400 rotates and reciprocatingly changes the wind flow blown out by the reciprocating guide structure 400 to be directed to the surface of the filter structure 500 in an S-shape, and the reciprocating drive of the reciprocating guide structure 400 causes the filter structure 500 to intermittently squeeze the filter structure 500 to generate shaking to guide the sticky impurities out from the swing structure 600, and the shaking of the filter structure 500 drives the swing structure 600 to swing to cause the reciprocating guide structure 400 to generate shaking to better guide the impurities that are accidentally stuck to the filter structure 500, and the swinging of the swinging structure 600 can also better guide the impurities dropped from the filter structure 500 out of the outside of the box body 1;

[0035] The present invention takes into account that when laser cutting a stainless steel pipe, the laser cutting machine is started after the stainless steel pipe is clamped to perform laser cutting on the stainless steel pipe. However, smoke will appear during the laser cutting process, and most of the smoke generated is unguided, but the smoke is directly dispersed at will. The particles and gas molecules in the smoke will scatter and absorb the energy of the laser beam. When the smoke concentration is high during the laser cutting process, the energy of the laser reaching the surface of the cutting material will be reduced, resulting in a reduction in the cutting speed, insufficient cutting depth, or even failure to complete the cutting task, which seriously affects the cutting quality. Therefore, the smoke can be guided to the surface of the filter structure 500 and filtered by the rotation of the fan 404, and the reciprocating guide structure 400 can also drive the reciprocating plate 403 and the guide plate 408 to reciprocate when rotating, so that the wind flow blown out by the fan 404 is guided to an S shape, so that the smoke in the guide flow can be more evenly contacted with the filter structure 500 and filtered, effectively preventing the filter structure 500 from being blocked and affecting the subsequent filtering effect.

[0036] Moreover, the smoke may contain tiny particles such as (metal particles, metal oxides, etc.) and irritating gases such as (ozone, nitrogen oxides, etc.), which may not only easily cause the surface of the laser cutting equipment to stick with debris, but also the operator may easily inhale these substances by mistake, causing symptoms such as coughing, wheezing, and sore throat. Long-term exposure to this environment may increase the incidence of respiratory diseases such as chronic bronchitis and emphysema, which may not only affect the effect of subsequent laser cutting, but also affect the personal safety of the staff. Therefore, when the reciprocating guide structure 400 reciprocates to guide the airflow, the wedge plate 502 and the gauze 503 may be driven to move intermittently up and down, so that the movement of the gauze 503 may shake the impurities sticking to the surface and drop them to the outside of the box 1, thereby preventing The gauze 503 is prevented from being blocked when used for a long time and the service life of the gauze 503 is increased. When the reciprocating rod 504 moves, the wiping plate 506 can clean the impurities stuck in the smoke on the surface of the laser device 3, thereby reducing the oxide layer on the surface of the laser device 3 and improving the effect and service life of subsequent laser welding of the laser device 3. The wiping plate 506 can be shaken up and down to drive the arc plate 601 to move, contact the dust outlet 604 and clean the impurities stuck on the surface of the dust outlet 604, thereby improving the impurities dropped from the gauze 503 to be better guided to the outside of the box 1. At the same time, the swing of the arc plate 601 can make the first wave block 602 and the second wave block 603 contact, thereby driving the guide plate 408 to remove the impurities stuck on the guide plate 408 when reciprocatingly guiding the smoke.

[0037] In order to realize the laser cutting of stainless steel tubes, the following specific structures need to be disclosed in detail, please refer to Figure 1-Figure 3 The discharge port 2 opened inside the box body 1 is adapted to the stainless steel pipe, and the laser device 3 detachably installed inside the box body 1 is set in a cone shape;

[0038] First, the staff pushes the stainless steel pipe into the box 1 through the discharge port 2 and passes through the box 1, and then drives the laser device 3 to laser cut the surface of the stainless steel pipe through the staff control panel. After the laser cutting, the staff pushes the stainless steel pipe again, guides the stainless steel pipe out of the box 1 from the discharge port 2 in another direction and collects it;

[0039] In order to guide the smoke generated by laser cutting of stainless steel pipes, the following specific structures need to be disclosed in detail, please refer to Figure 4-Figure 7 The reciprocating guide structure 400 includes a motor 401, which is fixedly connected to the inner side of the box body 1, and the output shaft end of the motor 401 is fixedly connected to a rotating gear 402, and the end of the rotating gear 402 away from the motor 401 is fixedly connected to a fan 404, and the surface of the rotating gear 402 is meshed with a first tooth 405;

[0040] The top of the first tooth 405 is fixedly connected to the reciprocating plate 403, and the inside of the reciprocating plate 403 is also fixedly connected to the second tooth 406. The outer ring surface of the reciprocating plate 403 is slidably connected to the limit plate 407, and the limit plate 407 is fixedly connected to the inner side of the box body 1. The side of the limit plate 407 away from the reciprocating plate 403 is fixedly connected to the fan 404, and both ends of the reciprocating plate 403 are fixedly connected to the guide plate 408;

[0041] During the laser cutting process of the stainless steel pipe by the laser device 3, the surface of the stainless steel pipe can be quickly heated to the ignition temperature under the irradiation of the laser beam, and then a combustion reaction occurs with oxygen to release a large amount of heat, so that small holes are formed inside the material, and the small holes are surrounded by molten metal walls. These steam and molten metal will float near the laser cutting, thus forming dust and smoke. Then, during the laser cutting process of the laser device 3, the staff starts the motor 401 to rotate the rotating gear 402 fixedly connected to the output shaft end. The rotation of the rotating gear 402 can drive the fan 404 to rotate and generate wind force, so as to guide and blow the smoke generated by the laser cutting process of the laser device 3 toward the filtering structure 500;

[0042] When the rotating gear 402 rotates forward, it drives the first teeth 405 meshed with the surface to move toward the inside of the box body 1, and then the movement of the first teeth 405 drives the reciprocating plate 403 to slide inside the limit plate 407, and synchronously drives the two sets of guide plates 408 to move toward the inside of the box body 1, and then the rotating gear 402 continues to rotate to disengage the first teeth 405, and mesh with the second teeth 406 to drive the second teeth 406 to move toward the other side of the box body 1. Then, the reciprocating plate 403 will be driven to move toward the other side of the box body 1, so that the reciprocating plate 403 can continuously reciprocate inside the limit plate 407, and then the reciprocating motion of the reciprocating plate 403 will drive the two sets of guide plates 408 to reciprocate, so that the wind force generated by the fan 404 will be guided to the surface of the filter structure 500 in an S shape through the reciprocating motion of the guide plates 408. The S-shaped guide of the smoke can better make the smoke contact with the filter structure 500 evenly, which is convenient for the subsequent filtering of the smoke.

[0043] In order to filter impurities from smoke, the following specific structure needs to be disclosed in detail, please refer to Figure 8-Figure 12 The filtering structure 500 includes a wedge block 501 and a U-shaped plate 505. The wedge block 501 is fixedly connected to the surface of the guide plate 408. The U-shaped plate 505 is fixedly connected to the surface of the box 1. A reciprocating rod 504 is slidably connected inside the U-shaped plate 505. Two groups of wedge plates 502 are fixedly connected to the outer annular surface of the reciprocating rod 504. The surfaces of the two groups of wedge plates 502 are fixedly connected with a gauze 503. The outer annular surface of the reciprocating rod 504 is also fixedly connected with a wiping plate 506.

[0044] When the reciprocating guide structure 400 blows the smoke toward the filtering structure 500, the gauze 503 will first come into contact with the smoke and, driven by the wind, will pass the smoke through the surface of the gauze 503, thereby filtering the smoke, and the impurities in the smoke will stick to the surface of the gauze 503, and the smoke will be discharged to the outside of the box body 1. Then, when the guide plate 408 reciprocates to guide the smoke, it will also drive the wedge block 501 to reciprocate, and then the wedge block 501 will contact the wedge plate 502 and drive the wedge plate 502 to move toward the top of the U-shaped plate 505. The movement of the wedge plate 502 will drive the reciprocating rod 504 to move synchronously, and the movement of the reciprocating rod 504 will drive the wiping plate 506 to move synchronously. Because the middle part of the two groups of wiping plates 506 is provided with a sliding groove that is compatible with the laser device 3, when the two groups of wiping plates 506 move, they can wipe the surface of the laser device 3 to prevent the surface of the laser device 3 from being The smoke is invaded to form an oxide layer, and then the movement of the wedge plate 502 drives the screen 503 to move, and the guide plate 408 is constantly reciprocating. Therefore, the two groups of wedge blocks 501 and the wedge plate 502 will be in constant contact with each other, so that the screen 503 can be constantly shaken, so that the impurities sticking to the surface of the screen 503 can be shaken off to the swing structure 600 and discharged to the outside of the box body 1, and the screen 503 can be prevented from being blocked and the service life of the screen 503 can be improved. Since the guide plate 408 reciprocates to guide the smoke to the surface of the screen 503, when the guide plate 408 guides the smoke to one side of the screen 503, the other side of the screen 503 is blocked by the guide plate 408, so the impurities sticking to the surface of the screen 503 that are blocked will fall off, and vice versa, the same is true for the other side of the screen 503. Even if the fan 404 keeps generating wind, the impurities sticking to the screen 503 can fall off to the outside of the box body 1.

[0045] In order to achieve the effect of wiping and discharging the impurities stuck to the reciprocating guide structure 400 by the swing structure 600, the following specific structure needs to be disclosed in detail, please refer to Figure 8-Figure 12 The swing structure 600 includes an arc plate 601, a second wave block 603 and a dust outlet 604. The top of the arc plate 601 is rotatably connected to the wiping plate 506. The first wave block 602 is fixedly connected to both sides of the arc plate 601. The dust outlet 604 is opened at the bottom of the box body 1. The second wave block 603 is fixedly connected to the inner wall of the guide plate 408.

[0046] When the wiping plate 506 is driven by the reciprocating rod 504 to move up and down, the movement of the wiping plate 506 will also drive the curved plate 601 to move. Since the dust outlet 604 is set as an inclined surface and the bottom of the curved plate 601 is also set as an inclined surface, when the wiping plate 506 moves to lift the curved plate 601, the bottom of the curved plate 601 will not contact the inclined surface of the dust outlet 604, so that the curved plate 601 is in a vertical state of the wiping plate 506, which is convenient for the subsequent contact between the first wave block 602 and the second wave block 603. Then, when the wiping plate 506 is reset, it will also drive the wiping plate 506 to reset and the curved plate 601 to reset. The moving inclined surface of the curved plate 601 will contact the inclined surface of the dust outlet 604, so that the curved plate 6 01 is tilted, and the impurities remaining on the inclined surface of the dust outlet 604 are cleaned and discharged, thereby improving the effect of the gauze 503 in discharging impurities, and the movement of the arc plate 601 will drive the first wave block 602 to move synchronously. Since the second wave block 603 fixedly connected to the inner side of the guide plate 408 is adapted to the first wave block 602, the first wave block 602 will continuously contact the second wave block 603 when moving, causing the guide plate 408 to vibrate, thereby clearing the impurities sticking to the surface of the guide plate 408, preventing the guide plate 408 from accumulating for a long time and reducing the guide effect of the guide plate 408, or even causing uneven guide, thereby completing the treatment of the smoke generated by the laser cutting of the laser device 3;

[0047] In order to better realize the reciprocating flow guiding of the reciprocating guide structure 400, the following specific structure needs to be disclosed in detail, please refer to Figure 4-Figure 7 Two groups of guide plates 408 are symmetrically arranged along the center of the reciprocating plate 403. The surface of the reciprocating plate 403 is provided with a slide groove that matches the guide plate 408. The first teeth 405 and the second teeth 406 that are fixedly connected inside the reciprocating plate 403 are obliquely symmetrically arranged. The surfaces of the first teeth 405 and the second teeth 406 are matched with the rotating gear 402.

[0048] In order to better realize the filtering structure 500 to filter impurities, the following specific structure needs to be disclosed in detail, please refer to Figure 8-Figure 12 , two groups of wedge blocks 501, wedge plates 502, reciprocating rods 504 and wiping plates 506 are symmetrically arranged along the center of the U-shaped plate 505, the outer ring surfaces of the two groups of reciprocating rods 504 are provided with return springs, the middle of the wiping plate 506 is provided with a slide groove adapted to the laser device 3, and the inclined surface of the wedge block 501 is adapted to the inclined surface of the wedge plate 502;

[0049] In order to better realize the effect of the swing structure 600 on the reciprocating guide structure 400 and the filtering structure 500, the following specific structures need to be disclosed in detail. Please refer to Figure 8-Figure 12The bottom of the arc plate 601 and the inclined surface of the dust outlet 604 are adapted to each other, and a plurality of groups of first wave blocks 602 fixedly connected to the side of the arc plate 601 are provided, and the second wave blocks 603 provided on the surface of the first wave blocks 602 are adapted to each other.
