Description

Technical Field

[0002] Metal cutting is a processing method that divides metal materials into predetermined shapes and sizes. It is widely used in the manufacturing and mechanical processing fields. With the development of science and technology, metal cutting technology has become increasingly diversified and refined. Laser cutting represents the forefront of modern precision processing technology. A high-energy-density laser beam is used to irradiate the metal surface, causing the material to melt and evaporate rapidly, forming a precise incision.

[0003] Existing laser cutting equipment usually produces a certain amount of slag during the metal cutting process due to the melting and oxidation reaction of the metal under high temperature. The produced slag will fall down onto the cutting table. The slag dropped on the cutting table is not only difficult to clean manually, but also sticky due to its own high temperature during the slag generation process. In addition, it will also produce a certain amount of smoke due to the high cutting temperature, which not only pollutes the air but also causes harm to the operator. Summary of the invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a cutting method of a laser cutting device for metal cutting. Through the cutting method of the laser cutting device for metal cutting, the slag can be cleaned and collected while the exhaust gas can be filtered.

[0033] The slag is removed by moving the scraping plate 203 inside the cleaning mechanism 200, and the high-temperature slag is cooled by squeezing out the water component 207; The exhaust gas is treated by the cooperation of the activated carbon filter plate 307 inside the exhaust gas treatment mechanism 300 and the drum fan 301.

[0034] The moving plate 201 inside the mobile cleaning mechanism 200 drives the scraping plate 203 to scrape away the slag inside the cutting groove 107. When the scraping plate 203 scrapes away the slag sticking due to high temperature, it will be squeezed and thus cooperate with the forward and backward moving component 205 to move the scraping plate 203 forward and backward.

When the exhaust gas enters the installation groove 302 through the air inlet 306, it will be filtered and treated by activated carbon.

[0039] The extruded water assembly 207 includes a filling pipe 207a, and water tanks 207b are fixedly installed on the front and rear sides of both sides of the top of the movable plate 201. Both ends of the filling pipe 207a are connected to the water tank 207b. The bottom of the water tank 207b is fixedly connected to a one-way three-way valve pipe 207c. The front and rear ends of the one-way three-way valve pipe 207c are fixedly connected to a fixed pipe 207d. The outer end of the fixed pipe 207d is fixedly connected to a telescopic hose 207e. The end of the telescopic hose 207e away from the fixed pipe 207d is connected to the scraping plate. The inner side of 203 is fixedly connected, a water pipe 207f is fixedly installed on the top of the scraping plate 203, the top of the water pipe 207f is fixedly connected with a nozzle 207g, a plurality of nozzles 207g are arranged and are distributed at equal distances, the end of the telescopic hose 207e away from the fixed pipe 207d is connected to the water pipe 207f, the top of the scraping plate 203 is fixedly connected with a protective cover 207h, the protective cover 207h is located on the top of the water pipe 207f, and the top of the water tank 207b is fixedly connected with a water level detection component 207i.

[0040] The auxiliary collecting component 204e includes a cam 204e-1, and inclined grooves 204e-2 are provided on both sides of the bottom of the inner wall of the cutting groove 107. The inner side of the inner wall of the inclined groove 204e-2 is fixedly connected with a fixed shaft 204e-3, and the surface of the fixed shaft 204e-3 is movably connected with an inclined plate 204e-4. The front and rear sides of the top of the inclined plate 204e-4 are fixedly connected with a transmission frame 204e-5, and the transmission frame 204e-5 is movably connected to the cam 204e-1. The outer side of the bottom of the inclined plate 204e-4 is movably connected with a rubber spring plate 204e-6, and the bottom of the rubber spring plate 204e-6 is fixedly connected to the bottom of the inner wall of the inclined groove 204e-2. The outer side of the bottom of the inner wall of the inclined groove 204e-2 is movably connected with a collecting box 204e-7.

[0041] The water level detection component 207i includes a fixed ring 207i-1, the inner wall of which is movably connected to a sealing rod 207i-2, the bottom of the sealing rod 207i-2 is fixedly connected to a floating ball 207i-3, and the top of the sealing rod 207i-2 is fixedly connected to a prompt ball 207i-4.

[0042] Specifically, by starting the motor 204b inside the fixed slot 204a, the screw 204c can be driven to rotate, so that after the screw 204c rotates, the movable plate 201 can be driven to move through the screw sleeve 204d, thereby facilitating the user to drive the movable plate 201 and the scraping plate 203 to clean the slag, and at the same time, it is convenient for the user to change the moving direction of the movable plate 201.

[0043] When the scraping plate 203 moves toward the movable plate 201, the positioning pin 205a is driven to move inside the guide groove 205b, so that the cooperation of the positioning pin 205a and the guide groove 205b can make the scraping plate 203 move back and forth when moving, so as to facilitate the scraping of sticky slag.

[0044] When the scraping plate 203 moves toward the movable plate 201, it will squeeze the telescopic hose 207e, so that the water inside the telescopic hose 207e can be injected into the water pipe 207f after being squeezed and sprayed outward through the nozzle 207g. The water flow sprayed by the nozzle 207g will be blocked by the protective cover 207h, so that the water flow can flow according to the inclination of the scraping plate 203 to cool the high-temperature slag.

[0045] When the motor 204b drives the screw 204c to rotate, the cam 204e-1 will also rotate synchronously, and the rubber spring plate 204e-6 will drive the inclined plate 204e-4 on the surface of the fixed shaft 204e-3 to move upward through its own elastic force, so that the transmission frame 204e-5 on the inclined plate 204e-4 will always be in contact with the cam 204e-1. When the protruding position of the cam 204e-1 is downward, it will squeeze the transmission frame 204e-5 downward. When the protruding position of the cam 204e-1 is upward, the inclined plate 204e-4 will move upward due to the elastic force of the rubber spring plate 204e-6 to reset, so that the inclined plate 204e-4 can vibrate reciprocatingly to facilitate the collection of the slag that falls into the inclined groove 204e-2, while preventing the slag from sticking to the inclined plate 204e-4.

[0046] As the liquid inside the water tank 207b replenishes the telescopic hose 207e, the water level inside the water tank 207b will gradually drop, causing the float 207i-3 on the water level to drop along with the water level, and the sealing rod 207i-2 on the float 207i-3 will drive the prompt ball 207i-4 to drop, so that the drop of the prompt ball 207i-4 can be convenient for the user to observe and replenish the water tank 207b through the filling tube 207a.

[0047] Furthermore, after the laser controller 105 starts the laser cutting head 106 to cut the metal inside the cutting groove 107, the motor 204b inside the fixed groove 204a is started, so that after the motor 204b is started, it can drive the screw 204c to rotate, so that after the screw 204c rotates, it can drive the screw sleeve 204d to move to one side, so that the screw sleeve 204d can drive the movable plate 201 to move to one side, so that after the movable plate 201 moves, it can drive the scraping plate 203 to move, so that the scraping plate 203 can push and clean the slag dropped on the cutting groove 107 when moving.

[0048] When the scraping plate 203 faces sticky slag due to high temperature during its movement, the scraping plate 203 will move toward the movable plate 201. When the scraping plate 203 moves toward the movable plate 201, it drives the positioning pin 205a to move inside the guide groove 205b, so that the positioning pin 205a drives the scraping plate 203 to move toward the movable plate 201 along the curved route of the guide groove 205b, so that the scraping plate 203 will move back and forth in this process, so that the scraping plate 203 can more conveniently scrape off the sticky slag when it moves back and forth, and at the same time compress the return spring 208.

[0049] When the scraping plate 203 moves toward the movable plate 201, it will squeeze the telescopic hose 207e, so that after the telescopic hose 207e is started and squeezed, the water flow inside the telescopic hose 207e will enter the water pipe 207f, and as the telescopic hose 207e is continuously squeezed, the water flow will be sprayed out through the nozzle 207g on the water pipe 207f. At the same time, the protective cover 207h blocks the sprayed water flow, so that the water flow will pass through the scraping plate 203 and flow to the sticky slag caused by high temperature, so that the water flow can cool the slag after contacting the slag, making it easier for the movable plate 201 to scrape off the slag.

[0050] After the scraping plate 203 scrapes off the sticky slag, it loses its resisting force on the slag, so that the reset spring 208 can drive the scraping plate 203 to reset through its own elastic force. During the resetting process of the scraping plate 203, the telescopic hose 207e will be stretched, so that the water stored in the water tank 207b can flow into the fixed pipe 207d through the one-way three-way valve pipe 207c, and the water flow can flow into the telescopic hose 207e again through the fixed pipe 207d, thereby filling the telescopic hose 207e with water, so that the water flow can be sprayed out through the nozzle 207g again after the telescopic hose 207e is squeezed next time.

[0051] When the motor 204b drives the screw 204c to rotate, the cam 204e-1 on the output end of the motor 204b and the surface of the screw 204c will rotate synchronously. As the cam 204e-1 rotates, the transmission frame 204e-5 will be driven to move downward, so that the transmission frame 204e-5 will drive the inclined plate 204e-4 on the surface of the fixed shaft 204e-3 to move downward, so that the inclined plate 204e-4 will move downward to deform the rubber spring plate 204e-6. After the cam 204e-1 is separated from the transmission frame 204e-5, the transmission frame 204e-5 loses the ability to press down the inclined plate 204e-4. The rubber spring plate 204e-6 will reset due to its own elasticity, so that the rubber spring plate 204e-6 will drive the inclined plate 204e-4 on the surface of the fixed shaft 204e-3 to reset, and the inclined plate 204e-4 will drive the transmission frame 204e-5 to move upward and reset. As the cam 204e-1 rotates, it will drive the transmission to move downward again, so that the inclined plate 204e-4 can move up and down and vibrate reciprocatingly, so that the slag falling into the inclined groove 204e-2 can be affected by the vibration of the inclined plate 204e-4 and can quickly fall into the collection box 204e-7 to facilitate the collection of the slag.

[0052] When the water tank 207b is in use, the liquid inside will gradually decrease, causing the float 207i-3 at the bottom of the sealing rod 207i-2 to drop as the liquid level drops, so that the float 207i-3 can drive the prompt ball 207i-4 to move downward through the sealing rod 207i-2 inside the fixed ring 207i-1, thereby facilitating the user to observe the liquid capacity inside the water tank 207b and to facilitate the user to refill the water tank 207b through the filling tube 207a.

The knocking cleaning rack 304a is movably connected to the movable plate 201, and the knocking cleaning rack 304a is movably connected to the activated carbon filter plate 307.

[0057] Specifically, when the movable plate 201 moves, the gear 303b will be driven to move, so that the gear 303b will mesh with the tooth groove 303a when it moves, so that the gear 303b can rotate, and the gear 303b can drive the transmission bevel gear 303f to rotate through the connecting rod 303d, so that the transmission bevel gear 303f can drive the transmission rod 303h to rotate through the driven bevel gear 303g, so that the transmission rod 303h can drive the transmission pulley 303i to rotate, and after the transmission pulley 303i rotates, it can drive the driven pulley 303j to rotate through the transmission belt 303k, and after the driven pulley 303j rotates, it can drive the drum fan 301 to rotate, so that the drum fan 301 close to the moving direction of the movable plate 201 can suck in the outside air through the air inlet 306 and discharge it through the exhaust port 305, so that the outside air carries the exhaust gas and is filtered by the activated carbon filter plate 307, thereby filtering the exhaust gas.

[0058] As the scraping plate 203 is reset, the knocking cleaning frame 304a will be driven to reset inside the sliding groove 304b. After the knocking cleaning frame 304a is reset, the activated carbon filter plate 307 can be filtered, so that the floating dust on the surface of the activated carbon filter plate 307 falls off after being vibrated, avoiding the floating dust from clogging the activated carbon filter plate 307.

[0059] Furthermore, when the moving plate 201 moves, the gear 303b will be driven to move along, and since the gear 303b is meshed with the tooth groove 303a, the gear 303b itself rotates, so that the gear 303b can drive the connecting rod to rotate after the rotation, so that the connecting rod 303d can drive the transmission bevel gear 303f inside the linkage groove 303c to rotate after the rotation, so that the transmission bevel gear 303f can drive the driven bevel gear 303g to rotate after the rotation, so that the driven bevel gear 303g can drive the transmission rod 303h to rotate after the rotation, so that the transmission rod 303h can drive the transmission pulley 303i inside the transmission groove 303e to rotate, so that the transmission pulley 30 After 3i rotates, it drives the driven pulley 303j to rotate through the transmission belt 303k, so that the driven pulley 303j can drive the two drum fans 301 inside the installation slot 302 to rotate after the rotation, so that the drum fan 301 close to the moving direction of the movable plate 201 can suck the air at the movable plate 201 into the installation slot 302 through the air inlet 306 and discharge it through the exhaust port 305, and the inhaled air will carry the waste gas generated by the slag into the air inlet 306, so that the waste gas can be filtered by the activated carbon filter plate 307 inside the air inlet 306 after passing through the air inlet 306, so that the activated carbon filter plate 307 can filter the waste gas.

[0060] When the scraping plate 203 moves outward to reset, it will drive the knocking cleaning frame 304a to move outward inside the sliding groove 304b, so that the knocking cleaning frame 304a can knock on the activated carbon filter plate 307, so that the dust on the surface of the activated carbon filter plate 307 can fall off after being vibrated, thereby avoiding the clogging of the activated carbon filter plate 307.

[0061] The remaining structure is the same as that of Example 2.

[0062] Reference Figures 1 to 7 , which is the fourth embodiment of the present invention, is different from the third embodiment in that: a laser cutting device for metal cutting.

[0063] After the laser controller 105 starts the laser cutting head 106 to cut the metal inside the cutting groove 107, the motor 204b inside the fixed groove 204a is started, so that the motor 204b can drive the screw 204c to rotate after starting, and the screw 204c can drive the screw sleeve 204d to move to one side after rotating, so that the screw sleeve 204d can drive the movable plate 201 to move to one side, and the movable plate 201 can drive the scraping plate 203 to move after moving, so that the scraping plate 203 can push and clean the slag dropped on the cutting groove 107 when moving.

[0064] When the scraping plate 203 faces sticky slag due to high temperature during its movement, the scraping plate 203 will move toward the movable plate 201. When the scraping plate 203 moves toward the movable plate 201, it drives the positioning pin 205a to move inside the guide groove 205b, so that the positioning pin 205a drives the scraping plate 203 to move toward the movable plate 201 along the curved route of the guide groove 205b, so that the scraping plate 203 will move back and forth in this process, so that the scraping plate 203 can more conveniently scrape off the sticky slag when it moves back and forth, and at the same time compress the return spring 208.

[0065] When the scraping plate 203 moves toward the movable plate 201, it will squeeze the telescopic hose 207e, so that after the telescopic hose 207e is started and squeezed, the water flow inside the telescopic hose 207e will enter the water pipe 207f, and as the telescopic hose 207e is continuously squeezed, the water flow will be sprayed out through the nozzle 207g on the water pipe 207f. At the same time, the protective cover 207h blocks the sprayed water flow, so that the water flow will pass through the scraping plate 203 and flow to the sticky slag caused by high temperature, so that the water flow can cool the slag after contacting the slag, making it easier for the movable plate 201 to scrape off the slag.

[0066] After the scraping plate 203 scrapes off the sticky slag, it loses its resisting force on the slag, so that the reset spring 208 can drive the scraping plate 203 to reset through its own elastic force. During the resetting process of the scraping plate 203, the telescopic hose 207e will be stretched, so that the water stored in the water tank 207b can flow into the fixed pipe 207d through the one-way three-way valve pipe 207c, and the water flow can flow into the telescopic hose 207e again through the fixed pipe 207d, thereby filling the telescopic hose 207e with water, so that the water flow can be sprayed out through the nozzle 207g again after the telescopic hose 207e is squeezed next time.

[0067] When the motor 204b drives the screw 204c to rotate, the cam 204e-1 on the output end of the motor 204b and the surface of the screw 204c will rotate synchronously. As the cam 204e-1 rotates, the transmission frame 204e-5 will be driven to move downward, so that the transmission frame 204e-5 will drive the inclined plate 204e-4 on the surface of the fixed shaft 204e-3 to move downward, so that the inclined plate 204e-4 will move downward to deform the rubber spring plate 204e-6. After the cam 204e-1 is separated from the transmission frame 204e-5, the transmission frame 204e-5 loses the ability to press down the inclined plate 204e-4. The rubber spring plate 204e-6 will reset due to its own elasticity, so that the rubber spring plate 204e-6 will drive the inclined plate 204e-4 on the surface of the fixed shaft 204e-3 to reset, and the inclined plate 204e-4 will drive the transmission frame 204e-5 to move upward and reset. As the cam 204e-1 rotates, it will drive the transmission to move downward again, so that the inclined plate 204e-4 can move up and down and vibrate reciprocatingly, so that the slag falling into the inclined groove 204e-2 can be affected by the vibration of the inclined plate 204e-4 and can quickly fall into the collection box 204e-7 to facilitate the collection of the slag.

[0068] When the water tank 207b is in use, the liquid inside will gradually decrease, causing the float 207i-3 at the bottom of the sealing rod 207i-2 to drop as the liquid level drops, so that the float 207i-3 can drive the prompt ball 207i-4 to move downward through the sealing rod 207i-2 inside the fixed ring 207i-1, thereby facilitating the user to observe the liquid capacity inside the water tank 207b and to facilitate the user to refill the water tank 207b through the filling tube 207a.

[0069] When the moving plate 201 moves, the gear 303b will be driven to move along. Since the gear 303b is meshed with the tooth groove 303a, the gear 303b itself rotates, so that the gear 303b can drive the connecting rod to rotate after the rotation, so that the connecting rod 303d can drive the transmission bevel gear 303f inside the linkage groove 303c to rotate after the rotation, so that the transmission bevel gear 303f can drive the driven bevel gear 303g to rotate after the rotation, so that the driven bevel gear 303g can drive the transmission rod 303h to rotate after the rotation, so that the transmission rod 303h can drive the transmission pulley 303i inside the transmission groove 303e to rotate after the rotation, so that the transmission pulley 303i After the rotation, the driven pulley 303j is driven to rotate through the transmission belt 303k, so that the driven pulley 303j can drive the two roller fans 301 inside the installation slot 302 to rotate after the rotation, so that the roller fan 301 close to the moving direction of the movable plate 201 can suck the air at the movable plate 201 into the installation slot 302 through the air inlet 306 and discharge it through the exhaust port 305. The inhaled air will carry the waste gas generated by the slag into the air inlet 306, so that the waste gas can be filtered by the activated carbon filter plate 307 inside the air inlet 306 after passing through the air inlet 306, so that the activated carbon filter plate 307 can filter the waste gas.

[0070] When the scraping plate 203 moves outward to reset, it will drive the knocking cleaning frame 304a to move outward inside the sliding groove 304b, so that the knocking cleaning frame 304a can knock on the activated carbon filter plate 307, so that the dust on the surface of the activated carbon filter plate 307 can fall off after being vibrated, thereby avoiding the clogging of the activated carbon filter plate 307.

[0071] In summary, the moving plate 201 drives the scraping plate 203 to scrape away the slag. When the scraping plate 203 encounters sticky slag during the process of scraping away the slag, the slag will be cooled by squeezing out the water component 207. At the same time, the front and rear moving components 205 are used to scrape away the cooled slag, and the exhaust gas is filtered in real time through the activated carbon filter plate 307.
