Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology for high-temperature alloy stainless steel plates, specifically a laser cutting device for high-temperature alloy stainless steel plates. Background Technology

[0002] Laser cutting machines, as powerful tools in modern advanced manufacturing, concentrate enormous energy onto the surface of a workpiece by precisely focusing a high-energy laser beam. When a laser irradiates a high-temperature alloy stainless steel plate with extremely high power density, the instantaneous high temperature can rapidly bring it to its melting point or even boiling point. With the synergistic effect of auxiliary gas, the material is efficiently vaporized or melted and blown away, forming a precise kerf, achieving non-contact, high-precision cutting operations, and is now widely used in industrial processing.

[0003] A patent with publication number CN113305429B discloses a stainless steel plate laser cutting device, including a movable base and a water tank fixedly installed on a platform. The movable base is equipped with a laser head via an electric telescopic rod. Two isolation covers are mounted on the upper end of the electric telescopic rod via a locking mechanism, and a positioning component is installed between the two isolation covers. A one-way pipe is fixedly connected to the isolation cover on the side away from the water tank. An air pump is fixedly installed on the water tank, and the air pump is connected to an air outlet pipe and an elastic pipe, with the elastic pipe fixedly connected to the isolation cover on the side closer to the water tank. A cover is locked onto the water tank, and a feeding component is installed on the cover. The advantages are: the use of isolation covers and rubber pads prevents dust generated during laser cutting from flying around, improving the environmental quality during use; and the water tank, elastic pipe, and air outlet pipe work together to transport some of the dust into the water tank for removal.

[0004] However, in actual production processes, when laser cutting high-temperature alloy stainless steel plates, the inherent nature of laser cutting is a combination of high-temperature thermal melting and high-pressure slag blowing. High-temperature alloy stainless steel has a high melting point, poor fluidity of molten metal, and a rapid cooling rate, making it easy for molten metal to remain at the cut edge. After cooling, this forms solidified metal protrusions, molten nodules, and burrs. Current treatment methods often involve subsequent grinding, which not only increases labor costs but also easily damages the cutting precision. This is because the hardness of the solidified metal protrusions, molten nodules, and burrs is the same as that of the high-temperature alloy stainless steel plate. At the same time, the laser cutting process generates a large amount of metal dust particles, including micron- and submicron-sized metal fumes, fine metal fragments, and oxide waste particles. These dust particles contain heavy metal elements and are easily suspended in the production environment, causing equipment wear and tear, harming the health of operators, and contaminating the surface of the sheet material, further increasing subsequent cleaning costs.

[0005] Therefore, the present invention provides a laser cutting device for high-temperature alloy stainless steel plates. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The high-temperature alloy stainless steel plate laser cutting equipment of the present invention includes a machine body. Two first guide rails are symmetrically arranged inside the machine body. A first guide plate is slidably connected to each first guide rail. The same second guide rail is fixed to the surface of the two first guide plates. A second guide plate is slidably connected to the surface of the second guide rail. A laser head is fixed to one side of the second guide plate. An alloy steel plate is clamped inside the machine body. A processing component is arranged on one side of the second guide plate. The processing component includes a fixing plate fixed to one side of the second guide plate. A symmetrically arranged limiting plate is fixed to one side of the fixing plate. A positioning frame is slidably arranged on the upper surface of the limiting plate. The positioning frame is inserted into the end face of the cut alloy steel plate. The positioning frame grinds the end face of the alloy steel plate. A limiting component is arranged inside the machine body. The limiting component includes a positioning groove opened inside the machine body. An alloy steel plate is clamped inside the positioning groove. A positioning push rod is arranged in one side of the positioning groove.

[0008] Preferably, the processing component further includes a limiting guide rail formed on the surface of the limiting plate, a connecting guide rail slidably connected inside the limiting guide rail, a connecting guide groove formed on the upper surface of the connecting guide rail, a connecting guide block slidably connected inside the connecting guide groove, a compression spring fixed to the bottom wall of the connecting guide block, a positioning frame fixed to the top of the compression spring, the positioning frame magnetically attracting the connecting guide block, and an electro-permanent magnet block provided on the inner bottom wall of the connecting guide block.

[0009] Preferably, the positioning frame has a slot inside, and the top and bottom walls of the slot are provided with two sets of fixing plates, which are made of sponge material.

[0010] Preferably, sliding grooves are provided on both sides of the connecting guide block, a sliding block is slidably connected inside the sliding groove, a sliding frame is fixed to one side of the sliding block, and a sliding guide plate is slidably connected inside the sliding frame. The sliding guide plate is used to guide the metal dust from grinding.

[0011] Preferably, the limiting component includes a positioning plate fixed to one side of the machine body, a positioning post slidingly penetrating the surface of the positioning plate, a top plate fixed to the top of the positioning post, two positioning springs fixed between the top plate and the positioning plate, and a positioning block fixed to the bottom of the positioning post, the positioning block having a conical cross-section.

[0012] Preferably, the positioning block has a positioning cavity inside, and the positioning cavity has an auxiliary component inside. The auxiliary component includes an auxiliary spring fixed to the top wall of the positioning cavity, an auxiliary block fixed to one end of the auxiliary spring, auxiliary rods fixed to both sides of the auxiliary block, the ends of the two auxiliary rods rotatably connected to the same auxiliary plate, a torsion spring rotatably connected between the two auxiliary rods, an auxiliary guide plate fixed to one side of the auxiliary block, and an auxiliary groove opened in the positioning cavity corresponding to the position of the auxiliary guide plate.

[0013] Preferably, a collection box is provided at the bottom of the machine body, and a collection frame is fixedly connected inside the machine body. The cross-section of the collection frame is grooved, and a filter plate is fixedly connected to the top of the collection frame. The filter plate is made of metal fiber filter material. An exhaust fan is also fixedly connected to one side of the collection frame. The exhaust fan assists the collection frame in collecting metal dust generated during the cutting and grinding process.

[0014] Preferably, when performing laser cutting of alloy steel plates, the alloy steel plates are first inserted along the positioning grooves opened inside the machine body, and then fixed by the limiting components. After the alloy steel plates are fixed, the first guide rail inside the machine body is activated. The first guide rail drives the first guide plate to move the second guide rail, moving the second guide rail to the end of the alloy steel plate. Then, the second guide rail is activated, driving the second guide plate to move the laser head to the cutting position. The laser head is then activated, and the desired cutting shape is obtained through the movement of the first and second guide rails. After laser cutting, the alloy steel plate is cut into two sections. At this time, the positioning push rod inside the machine body is activated, moving one section of the alloy steel plate to the side. Since the alloy steel plate is limited in the positioning groove, after one section of the alloy steel plate moves, a corresponding space is created between the two sections of the alloy steel plate. At this time, the second guide rail drives the fixing plate to move to the middle of the two alloy steel plates, and then the connecting guide block is activated. The electro-permanent magnet at the bottom repels the positioning frame. The positioning frames inside the two connecting guide blocks move upward, causing the second guide rail to drive one of the positioning frames to engage with the alloy steel plate. The positioning frame on the other side is pushed by the positioning push rod to engage with the positioning frame on one of the limit plates. After both alloy steel plates are engaged by the positioning frames, the connecting guide rail is activated. The connecting guide rail drives the connecting guide block to slide, which in turn drives the positioning frame to slide along the cut end face of the alloy steel plate. During the sliding process, the positioning groove inside the positioning frame is made of frosted material. At the same time, sponge material fixing plates are fixed to the top and bottom walls of the positioning groove, which can be used to wipe the positioning frame during grinding. The metal dust that is ground will slide down along the sliding frames and sliding guide plates on both sides of the positioning frame into the collection component. The sliding frame moves upward as the positioning frame moves upward. When it moves to the top, the internal guide rail of the sliding frame is activated, extending the sliding guide plate to guide the metal dust.

[0015] Preferably, during the process of limiting the alloy steel plate, when the alloy steel plate is inserted into the positioning groove, it will first squeeze the positioning block on one side of the machine body to move upward. Then, the alloy steel plate extends into the positioning groove. After the alloy steel plate is fully inserted into the positioning groove, the positioning block is reset under the reset force of the top positioning spring. At the same time, the auxiliary spring in the positioning cavity inside the positioning block is squeezed outward by the repulsive force of the electrophoretic magnetic block built into the top wall of the positioning block. The auxiliary spring drives the auxiliary block and the auxiliary rod to move out of the positioning cavity, so that the auxiliary plate rotatably connected to one end of the auxiliary rod abuts against the alloy steel plate located in the positioning groove. During the abutment process, the auxiliary plate will gradually rotate, so that the entire auxiliary plate abuts against the side of the alloy steel plate. During the movement of the auxiliary block, it will be limited along the auxiliary groove by the auxiliary guide plate on one side, thus completing the limiting work of the alloy steel plate.

[0016] Preferably, during the laser cutting and processing of alloy steel plates, the exhaust fans in the collection frame at the bottom of the machine are always running. The exhaust fans suck up the metal dust in the air, and the sucked metal dust settles in the collection box. Finally, the collection box is pulled out for unified processing of the metal dust.

[0017] The beneficial effects of this invention are as follows: 1. The high-temperature alloy stainless steel plate laser cutting equipment of this invention ensures the stability of the steel plate position during laser cutting by inserting the alloy steel plate into the positioning groove and fixing it with the limiting component, thereby improving cutting accuracy and ensuring that the cut shape meets the requirements. Secondly, the dual guide rails work together to drive the laser head to move, which can flexibly realize various complex shape cutting to meet diverse production needs. After cutting, the positioning push rod and the electro-permanent magnet block and other devices cooperate to form a space between the two alloy steel plates, which facilitates the positioning frame to lock in place and prepares for subsequent grinding. After cutting, the end face of the alloy steel plate is ground to avoid the alloy steel plate becoming too hard after the metal protrusion has completely cooled, making it difficult to grind. In addition, the positioning frame wraps around the cutting end face for sliding grinding, and the frosted positioning groove effectively removes burrs, improves the quality of the alloy steel plate, and has high grinding efficiency. At the same time, the sponge fixing plate can also wipe the steel plate, and the metal dust can slide to the collection component in time to avoid dust pollution and harm to workers' health. At the same time, the guiding of the sliding guide plate makes dust collection more efficient, which improves overall production efficiency and product quality.

[0018] 2. The high-temperature alloy stainless steel plate laser cutting equipment of the present invention, when the alloy steel plate is inserted into the positioning groove, the positioning block moves upward first. After the steel plate is fully inserted, the positioning spring resets the positioning block. At the same time, the repulsive force of the electrophoretic magnetic block causes the auxiliary spring to drive the auxiliary block, auxiliary rod and auxiliary plate to move and abut against the side of the steel plate. The rotation of the auxiliary plate ensures full fit. The movement of the auxiliary guide plate along the auxiliary groove also plays a limiting role, so that the alloy steel plate is firmly fixed in the positioning groove, effectively avoiding the shaking of the steel plate during cutting, greatly improving the cutting accuracy and quality. In terms of dust treatment, the exhaust fan in the collection frame at the bottom of the machine operates throughout the laser cutting and processing process, which can timely suck the metal dust in the air into the collection box and let it settle, preventing dust from spreading in the working environment, protecting the health of workers, and reducing the corrosion of equipment by dust. Finally, the collection box is pulled out to dispose of the dust. The operation is simple and improves the cleanliness and environmental protection of the overall production process.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 9 As shown in the embodiment of the present invention, a high-temperature alloy stainless steel plate laser cutting equipment has two first guide rails symmetrically arranged inside the machine body 1. Each first guide rail 11 is slidably connected to a first guide plate 12. The same second guide rail 13 is fixed to the surface of the two first guide plates 12. A second guide plate 14 is slidably connected to the surface of the second guide rail 13. A laser head 16 is fixed to one side of the second guide plate 14. An alloy steel plate 3 is clamped inside the machine body 1. A processing component is arranged on one side of the second guide plate 14. The processing component includes a fixing plate 15 fixed to one side of the second guide plate 14. A symmetrically arranged limiting plate 5 is fixed to one side of the fixing plate 15. A positioning frame 55 is slidably arranged on the upper surface of the limiting plate 5. The positioning frame 55 is inserted into the end face of the cut alloy steel plate 3. The positioning frame 55 grinds the end face of the alloy steel plate 3. A limiting component is arranged inside the machine body 1. The limiting component includes a positioning groove 21 opened inside the machine body 1. An alloy steel plate 3 is clamped inside the positioning groove 21. One of the positioning slots 21 has a positioning push rod 22; the processing component also includes a limiting guide rail 51 on the surface of the limiting plate 5, a connecting guide rail 52 slidably connected inside the limiting guide rail 51, a connecting guide groove 53 on the upper surface of the connecting guide rail 52, a connecting guide block 54 slidably connected inside the connecting guide groove 53, a compression spring 512 fixed to the bottom wall of the connecting guide block 54, a positioning frame 55 fixed to the top of the compression spring 512, the positioning frame 55 and the connecting guide block 54 magnetically attracted, and the connecting guide block 54... The bottom wall of the part is provided with an electro-permanent magnet block; the inside of the positioning frame 55 is provided with a slot 56, and the top and bottom walls of the slot 56 are provided with two sets of fixing plates 57, which are made of sponge material; both sides of the connecting guide block 54 are provided with sliding grooves 58, and sliding blocks 59 are slidably connected inside the sliding grooves 58. A sliding frame 510 is fixed to one side of the sliding block 59, and a sliding guide plate 511 is slidably connected inside the sliding frame 510. The sliding guide plate 511 is used to guide the metal dust from grinding.

[0023] Specifically, in actual production processes, when laser cutting high-temperature alloy stainless steel plates, the inherent nature of laser cutting is a combination of high-temperature thermal melting and high-pressure slag blowing. High-temperature alloy stainless steel has a high melting point, poor fluidity of molten metal, and a fast cooling rate, making it easy for molten metal to remain at the cut edge. After cooling, this forms solidified metal protrusions, molten nodules, and burrs. Current treatment methods often involve subsequent grinding, which not only increases labor costs but also easily damages the cutting precision. This is because the hardness of the solidified metal protrusions, molten nodules, and burrs is the same as that of the high-temperature alloy stainless steel plate. At the same time, the laser cutting process generates a large amount of metal dust particles, including micron- and submicron-sized metal fumes, fine metal fragments, and oxide waste particles. These dust particles contain heavy metal elements and are easily suspended in the production environment, causing equipment wear and tear, harming the health of operators, and contaminating the surface of the sheet material, further increasing subsequent cleaning costs. Therefore, the present invention addresses the above-mentioned problems by providing the aforementioned structure. Firstly, during laser cutting of the alloy steel plate 3, the alloy steel plate 3 is inserted along the positioning groove 21 inside the machine body 1. Then, the limiting component fixes the alloy steel plate 3. After fixing the alloy steel plate 3, the first guide rail 11 inside the machine body 1 is activated. The first guide rail 11 drives the first guide plate 12 to move the second guide rail 13, moving the second guide rail 13 to the end of the alloy steel plate 3. Then, the second guide rail 13 is activated, driving the second guide plate 14 to move the laser head. 16 moves to the cutting position, then the laser head 16 is activated, and the required cutting shape is obtained by the movement of the first guide rail 11 and the second guide rail 13. After the laser cutting is completed, the alloy steel plate 3 is cut into two sections. At this time, the positioning push rod 22 inside the machine body 1 is activated, which drives one section of the alloy steel plate 3 to move to the side. Since the alloy steel plate 3 is limited in the positioning groove 21, after one section of the alloy steel plate 3 moves, a corresponding space is opened between the two sections of the alloy steel plate 3. At this time, the second guide rail 13 drives the fixing plate 15 to move to the middle of the two alloy steel plates 3, and then the laser head 16 is activated. The electro-permanent magnet at the bottom of the connecting guide block 54 repels the positioning frame 55, causing the positioning frames 55 inside the two connecting guide blocks 54 to move upward. Then, the second guide rail 13 drives one of the positioning frames 55 to engage with the alloy steel plate 3, while the positioning frame 55 on the other side is pushed by the positioning push rod 22, causing that section of the alloy steel plate 3 to engage with the positioning frame 55 on one of the limiting plates 5. After both alloy steel plates 3 are engaged by the positioning frames 55, the connecting guide rail 52 is activated. The connecting guide rail 52 drives the connecting guide block 54 to slide, thereby causing the positioning frame 55 to be cut along the alloy steel plate 3. The cut end face slides, and during the sliding process, the positioning groove 21 inside the positioning frame 55 is made of frosted material. At the same time, the top and bottom walls of the positioning groove 21 are fixed with sponge material fixing plates 57, which can be used to wipe the positioning frame 55 when it is being polished. The metal dust that is polished will slide down along the sliding frames 510 and sliding guide plates 511 on both sides of the positioning frame 55 into the collection component. The sliding frame 510 moves up as the positioning frame 55 moves up. When it moves to the top, the internal guide rail of the sliding frame 510 is activated, and the sliding guide plate 511 is extended to guide the metal dust. By inserting the alloy steel plate 3 into the positioning groove 21 and fixing it with the limiting component during the laser cutting process, the stability of the steel plate position during cutting is ensured, improving cutting accuracy and ensuring that the cut shape meets the requirements. Secondly, the dual guide rails work together to drive the laser head 16 to move, which can flexibly realize the cutting of various complex shapes and meet diverse production needs. After cutting, the positioning push rod 22 cooperates with the electro-permanent magnet block and other devices to create space between the two alloy steel plates 3, which facilitates the locking of the positioning frame 55 and prepares for subsequent grinding. The end face of the alloy steel plate 3 is then ground to prevent the metal protrusions from becoming too hard and difficult to grind after they have completely cooled. In addition, the positioning frame 55 wraps around the cutting end face for sliding grinding, and the frosted positioning groove 21 effectively removes burrs, improving the quality of the alloy steel plate 3 and increasing grinding efficiency. At the same time, the sponge fixing plate 57 can also wipe the steel plate, and the metal dust can slide to the collection component in time, avoiding dust pollution and harm to workers' health. Meanwhile, the guiding of the sliding guide plate 511 makes dust collection more efficient, improving overall production efficiency and product quality.

[0024] Example 2: Figures 1 to 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the limiting component includes a positioning plate 2 fixedly attached to one side of the body 1, a positioning post 24 slidably passing through the surface of the positioning plate 2, a top plate 214 fixedly attached to the top of the positioning post 24, two positioning springs 23 fixedly connected between the top plate 214 and the positioning plate 2, a positioning block 25 fixedly attached to the bottom of the positioning post 24, the positioning block 25 having a conical cross-section; a positioning cavity 26 is provided inside the positioning block 25, an auxiliary component is provided inside the positioning cavity 26, the auxiliary component includes an auxiliary spring 28 fixedly attached to the top wall of the positioning cavity 26, an auxiliary block 29 fixedly attached to one end of the auxiliary spring 28, and auxiliary components fixedly attached to both sides of the auxiliary block 29. The two auxiliary rods 212 are rotatably connected to the same auxiliary plate 27 at their ends. A torsion spring 213 is rotatably connected between the two auxiliary rods 212. An auxiliary guide plate 210 is fixed to one side of the auxiliary block 29. An auxiliary groove 211 is opened in the positioning cavity 26 corresponding to the position of the auxiliary guide plate 210. A collection box 4 is set at the bottom of the machine body 1. A collection frame 41 is fixed inside the machine body 1. The cross-section of the collection frame 41 is grooved. A filter plate 43 is fixed to the top of the collection frame 41. The filter plate 43 is made of metal fiber filter material. An exhaust fan 42 is also fixed to one side of the collection frame 41. The exhaust fan 42 assists the collection frame 41 in collecting metal dust generated during the cutting and grinding process.

[0025] Specifically, during the process of limiting the alloy steel plate 3, when the alloy steel plate 3 is inserted into the positioning groove 21, it will first squeeze the positioning block 25 on one side of the machine body 1 to move upward. Then, the alloy steel plate 3 extends into the positioning groove 21. After the alloy steel plate 3 is fully inserted into the positioning groove 21, the positioning block 25 is reset under the reset force of the top positioning spring 23. The auxiliary spring 28 in the positioning cavity 26 inside the positioning block 25 is squeezed outward by the repulsive force of the electrophoretic magnetic block built into the top wall of the positioning block 25. The auxiliary spring 28 drives the auxiliary block 29 and the auxiliary rod 212 to move out of the positioning cavity 26, so that the auxiliary plate 27 rotatably connected to one end of the auxiliary rod 212 abuts against the alloy steel plate 3 located in the positioning groove 21. During the abutment process, the auxiliary plate 27 will gradually rotate, so that the entire auxiliary plate 27 abuts against the side of the alloy steel plate 3. During the movement of the auxiliary block 29, it will be limited along the auxiliary groove 211 by the auxiliary guide plate 210 on one side, thus completing the limiting work of the alloy steel plate 3. In addition, when the alloy steel plate 3 is laser-cut and processed, the exhaust fan 42 in the collection box 41 at the bottom of the machine body 1 is running. The exhaust fan 42 sucks up the metal dust in the air. The sucked metal dust settles in the collection box 4. Finally, the collection box 4 is pulled out to process the metal dust in a unified manner. When the alloy steel plate 3 is inserted into the positioning groove 21, the positioning block 25 moves upward first. After the steel plate is fully inserted, the positioning spring 23 resets the positioning block 25. At the same time, the repulsive force of the electrophoretic magnetic block causes the auxiliary spring 28 to drive the auxiliary block 29, auxiliary rod 212 and auxiliary plate 27 to move and abut against the side of the steel plate. The auxiliary plate 27 rotates to ensure full fit. The auxiliary guide plate 210 moves along the auxiliary groove 211 and also plays a limiting role, so that the alloy steel plate 3 is firmly fixed in the positioning groove 21, effectively preventing the steel plate from shaking during cutting, which greatly improves the cutting accuracy and quality. Then, in terms of dust treatment, the exhaust fan 42 in the collection frame 41 at the bottom of the machine body 1 runs throughout the laser cutting and processing work. It can timely suck the metal dust in the air into the collection box 4 and let it settle, preventing dust from spreading in the working environment, protecting the health of workers, and reducing the corrosion of equipment by dust. Finally, the collection box 4 is pulled out to dispose of the dust. The operation is simple and improves the cleanliness and environmental protection of the overall production process.

[0026] Working principle: First, when performing laser cutting of alloy steel plate 3, alloy steel plate 3 is inserted along the positioning groove 21 opened inside the machine body 1. Then, the limiting component fixes the alloy steel plate 3. After the alloy steel plate 3 is fixed, the first guide rail 11 inside the machine body 1 is activated. The first guide rail 11 drives the first guide plate 12 to move the second guide rail 13. The second guide rail 13 moves to the end of the alloy steel plate 3. Then, the second guide rail 13 is activated. The second guide rail 13 drives the second guide plate 14 to move the laser head 16 to the cutting position. The laser head 16 moves and, through the movement of the first guide rail 11 and the second guide rail 13, obtains the desired cutting shape. After laser cutting, the alloy steel plate 3 is cut into two sections. At this time, the positioning push rod 22 inside the machine body 1 is activated, driving one section of the alloy steel plate 3 to move to the side. Since the alloy steel plate 3 is limited in the positioning groove 21, after one section of the alloy steel plate 3 moves, a corresponding space is created between the two sections of the alloy steel plate 3. At this time, the second guide rail 13 drives the fixing plate 15 to move to the middle of the two alloy steel plates 3, and then the electric circuit at the bottom of the connecting guide block 54 is activated. The permanent magnet blocks repel the positioning frames 55. The positioning frames 55 inside the two connecting guide blocks 54 move upward, causing the second guide rail 13 to drive one side of the positioning frame 55 to engage with the alloy steel plate 3. The positioning frame 55 on the other side is pushed by the positioning push rod 22 to engage with the positioning frame 55 on one of the limiting plates 5. After both alloy steel plates 3 are engaged by the positioning frames 55, the connecting guide rail 52 is activated. The connecting guide rail 52 drives the connecting guide block 54 to slide, thereby driving the positioning frame 55 to move along the cut end face of the alloy steel plate 3. During the sliding process, the positioning groove 21 inside the positioning frame 55 is made of frosted material. At the same time, the top and bottom walls of the positioning groove 21 are fixed with sponge material fixing plates 57, which can be used to wipe the positioning frame 55 during polishing. The metal dust that is polished will slide down along the sliding frames 510 and sliding guide plates 511 on both sides of the positioning frame 55 into the collection component. The sliding frames 510 move upward as the positioning frame 55 moves upward. When it moves to the top, the internal guide rail of the sliding frame 510 is activated, extending the sliding guide plate 511 to guide the metal dust. By inserting the alloy steel plate 3 into the positioning groove 21 and fixing it with the limiting component during the laser cutting process, the stability of the steel plate position during cutting is ensured, improving cutting accuracy and ensuring that the cut shape meets the requirements. Secondly, the dual guide rails work together to drive the laser head 16 to move, which can flexibly realize the cutting of various complex shapes and meet diverse production needs. After cutting, the positioning push rod 22 cooperates with the electro-permanent magnet block and other devices to create space between the two alloy steel plates 3, which facilitates the locking of the positioning frame 55 and prepares for subsequent grinding. The end face of the alloy steel plate 3 is then polished to prevent the alloy steel plate 3 from becoming too hard and difficult to polish after the metal protrusions have completely cooled. In addition, the positioning frame 55 wraps around the cutting end face for sliding polishing, and the frosted positioning groove 21 effectively removes burrs, improves the quality of the alloy steel plate 3, and has high polishing efficiency. At the same time, the sponge fixing plate 57 can also wipe the steel plate, and the metal dust can slide to the collection component in time to avoid dust pollution of the environment and harm to workers' health. Meanwhile, the guide plate 511 makes dust collection more efficient, which improves overall production efficiency and product quality. During the process of limiting the alloy steel plate 3, when the alloy steel plate 3 is inserted into the positioning groove 21, it will squeeze the positioning block 25 on one side of the machine body 1 to move upward. Then, the alloy steel plate 3 extends into the positioning groove 21. After the alloy steel plate 3 is fully inserted into the positioning groove 21, the positioning block 25 is reset under the reset force of the top positioning spring 23. The auxiliary spring 28 in the positioning cavity 26 inside the positioning block 25 is squeezed outward by the repulsive force of the electrophoretic magnetic block built into the top wall of the positioning block 25. The auxiliary spring 28 drives the auxiliary block 29 and the auxiliary rod 212 to move out of the positioning cavity 26, so that the auxiliary plate 27 rotatably connected to one end of the auxiliary rod 212 abuts against the alloy steel plate 3 located in the positioning groove 21. During the abutment process, the auxiliary plate 27 will gradually rotate, so that the entire auxiliary plate 27 abuts against the side of the alloy steel plate 3. During the movement of the auxiliary block 29, it will be limited along the auxiliary groove 211 by the auxiliary guide plate 210 on one side, thus completing the limiting work of the alloy steel plate 3. In addition, when the alloy steel plate 3 is laser-cut and processed, the exhaust fan 42 in the collection box 41 at the bottom of the machine body 1 is running. The exhaust fan 42 sucks up the metal dust in the air. The sucked metal dust settles in the collection box 4. Finally, the collection box 4 is pulled out to process the metal dust in a unified manner. When the alloy steel plate 3 is inserted into the positioning groove 21, the positioning block 25 moves upward first. After the steel plate is fully inserted, the positioning spring 23 resets the positioning block 25. At the same time, the repulsive force of the electrophoretic magnetic block causes the auxiliary spring 28 to drive the auxiliary block 29, auxiliary rod 212 and auxiliary plate 27 to move and abut against the side of the steel plate. The auxiliary plate 27 rotates to ensure full fit. The auxiliary guide plate 210 moves along the auxiliary groove 211 and also plays a limiting role, so that the alloy steel plate 3 is firmly fixed in the positioning groove 21, effectively preventing the steel plate from shaking during cutting, which greatly improves the cutting accuracy and quality. Then, in terms of dust treatment, the exhaust fan 42 in the collection frame 41 at the bottom of the machine body 1 runs throughout the laser cutting and processing work. It can timely suck the metal dust in the air into the collection box 4 and let it settle, preventing dust from spreading in the working environment, protecting the health of workers, and reducing the corrosion of equipment by dust. Finally, the collection box 4 is pulled out to dispose of the dust. The operation is simple and improves the cleanliness and environmental protection of the overall production process.

After the alloy steel plate (3) is fixed, the first guide rail (11) inside the machine body (1) is started. The first guide rail (11) drives the first guide plate (12) to move the second guide rail (13) to the end of the alloy steel plate (3). Then, the second guide rail (13) is started. The second guide rail (13) drives the second guide plate (14) to move the laser head (16) to the cutting position. Then, the laser is started. The head (16) moves along the first guide rail (11) and the second guide rail (13) to obtain the required cutting shape. After laser cutting, the alloy steel plate (3) is cut into two sections. At this time, the positioning push rod (22) inside the machine body (1) is activated, which drives one section of the alloy steel plate (3) to move to the side. Since the alloy steel plate (3) is limited in the positioning groove (21), after one section of the alloy steel plate (3) moves, a corresponding space is left between the two sections of the alloy steel plate (3). At this time, the second guide rail (13) drives the fixing plate (15) to move to the middle of the two alloy steel plates (3), and then the electro-permanent magnet at the bottom of the connecting guide block (54) is activated. The block repels the positioning frame (55).

The positioning frame (55) on the other side is pushed by the positioning push rod (22) to engage with the positioning frame (55) on one of the limiting plates (5). After both alloy steel plates (3) are engaged by the positioning frames (55), the connecting guide rail (52) is started.

Then, the alloy steel plate (3) extends into the positioning groove (21). After the alloy steel plate (3) is completely inserted into the positioning groove (21), the positioning block (25) is reset under the reset force of the top positioning spring (23). The auxiliary spring (28) in the positioning cavity (26) inside the positioning block (25) is squeezed outward by the repulsive force of the electrophoretic magnetic block built into the top wall of the positioning block (25). When the auxiliary spring (28) moves, the auxiliary block (29) and the auxiliary rod (212) move out of the positioning cavity (26), so that the auxiliary plate (27) connected to one end of the auxiliary rod (212) comes into contact with the alloy steel plate (3) located in the positioning groove (21). During the contact process, the auxiliary plate (27) will gradually rotate, so that the entire auxiliary plate (27) comes into contact with the side of the alloy steel plate (3).
