Description

Technical Field

[0001] This application relates to the field of steel plate processing technology, and in particular to a flame cutting machine for steel plate processing. Background Technology

[0002] Currently, in industrial fields such as machinery manufacturing, steel structure construction, and shipbuilding, flame cutting machines for steel plate processing have become one of the core equipment for steel plate cutting and processing due to their advantages such as adaptability to medium and thick steel plates, cutting thickness ranging from several millimeters to hundreds of millimeters, low equipment purchase and maintenance costs, and convenient operation. Its working principle is to form a high-temperature flame by mixing combustible gas and oxygen to form a flame with a temperature that can reach over 3000℃, heating the part of the steel plate to be cut to the ignition point. Then, with the help of high-pressure oxygen flow, the high-temperature metal is violently oxidized and separated from the steel plate body, ultimately forming a cutting seam that conforms to the preset size and shape, thus realizing the segmentation and processing of steel plates. Commonly used combustible gases include acetylene and propane. However, existing flame cutting machines for steel plate processing have significant technological shortcomings in practical applications, which restrict the overall efficiency of steel plate processing and the smoothness of subsequent processes. On the one hand, after the cutting operation is completed, irregular melt particles will inevitably form at the edge of the steel plate cut. These melt particles have strong sharpness due to the characteristics of hot processing, which may not only pose safety hazards to operators in subsequent handling and assembly processes, but also affect the fit between the steel plate and other components. On the other hand, when flame cutting thick steel plates, due to the difference in heat conduction in the thickness direction of the steel plate and the effect of the cutting airflow, weld beads, which are common in welding processes, are easily generated at the cutting edge, accompanied by irregular sharp protrusions. To address the aforementioned issues during existing processing, a grinding and polishing step must be added to the current processing flow. This can be achieved either by manual grinding using hand tools, which is labor-intensive, time-consuming, and the polishing effect is inconsistent due to the operator's skill level, or by using dedicated polishing equipment for automated processing. However, this requires additional investment in equipment and space on top of the existing cutting production line, increasing the time cost of process transitions. Both manual grinding and dedicated equipment polishing must be set up independently outside the flame cutting process, extending the entire steel plate processing chain and significantly reducing processing efficiency. This fails to meet the demands of modern industrial production for efficient and continuous processing. Therefore, the design of existing flame cutting machines for steel plate processing has defects and deficiencies in the post-cutting treatment stage. Structural improvements and process optimization are urgently needed to achieve the integration and high efficiency of cutting and subsequent grinding and polishing processes, breaking through the current processing efficiency bottleneck.

This solves the problem of the need for additional polishing after cutting in the prior art, which leads to a complicated processing process and low overall operating efficiency. At the same time, this integrated design does not require additional configuration of dedicated polishing equipment, which reduces equipment purchase costs and eliminates the need to reserve space for polishing equipment. This achieves the effect of saving costs and production space, and solves the problem of additional investment in costs and space required by configuring dedicated polishing equipment in the prior art. During the application of this technical solution, by setting up an automated structure driven by multiple motors, the entire process of conveying, cutting, and polishing of the sheet metal can be automated. There is no need for manual hand-held tools for polishing, which reduces the labor intensity of operators. Moreover, the polishing parameters can be uniformly set and adjusted through the equipment control system to ensure that the polishing effect of the cut edges of different batches and different specifications of sheet metal is consistent. This achieves the effect of stable polishing quality and reduces reliance on manual labor. It solves the problems of high labor intensity of manual polishing and the difficulty in ensuring quality uniformity due to the influence of the operator's skill level in the existing technology. In addition, the automated conveying and positioning structure also avoids the errors when manually handling and adjusting the sheet metal, further improving the processing accuracy. During the application of this technical solution, the cooperative structure of the adjustment mechanism and the telescopic module, as well as the collaborative structure of the conveying mechanism and the positioning module, allows for flexible adjustment of the cutting mechanism position according to different sizes and thicknesses of the sheet material. This ensures that the sheet material does not shift or move during conveying and cutting, enabling cutting and polishing of both small, thin and large, thick sheet materials. This improves equipment adaptability and processing stability, solving the problems of poor adaptability to different sheet material specifications and low precision caused by easy shifting of sheet materials during processing in existing technologies. Furthermore, the polishing module adjusts synchronously with the cutting mechanism, ensuring that sheet materials of different specifications achieve flat cutting edges, further improving processing quality.

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0018] This application discloses a flame cutting machine for steel plate processing. For example... Figure 1-8 As shown, it includes a base frame 1, with conveyor frames 2 fixedly installed on the top left and right sides of the base frame 1, a conveying mechanism 3 fixedly installed on the top of the conveyor frame 2, an adjustment mechanism 4 fixedly installed on the top of one of the conveyor frames 2, a cutting mechanism 5 fixedly installed on the moving end of the adjustment mechanism 4, a positioning module 6 fixedly installed in the middle of the front and rear sides of the conveying mechanism 3, and a cutting steel plate placed on the top of the conveying mechanism 3. The cutting mechanism 5 includes a telescopic module 51, which is fixedly installed on the outside of the adjusting mechanism 4. An external arm 52 is fixedly installed on one side of the telescopic module 51, and the external arm 52 is movably connected between the inner sides of the two conveyor frames 2. A polishing module 53 is fixedly installed on the outside of the external arm 52. A connecting arm 54 is fixedly installed on the outside of the moving end of the telescopic module 51, and a flame cutting gun 55 is fixedly installed on the outer end of the connecting arm 54. During the application of this device, through the cooperation of the base frame 1, conveyor frame 2, conveying mechanism 3, adjusting mechanism 4, cutting mechanism 5 and positioning module 6, the steel plate to be cut can be placed on top of the conveying mechanism 3, and the conveying mechanism 3 will drive the plate to be conveyed towards the cutting mechanism 5. When the plate moves to the corresponding position, the positioning module 6 can position the plate to prevent it from shifting during processing. Then, the adjusting mechanism 4 drives the cutting mechanism 5 to move, adjusting the cutting mechanism 5 to a suitable position. In the cutting mechanism 5, the telescopic module 51 can adjust the height of the flame cutting gun 55, allowing it to precisely target the area of ​​the sheet metal to be cut. Simultaneously, the outer arm 52 of the cutting mechanism 5 is equipped with a polishing module 53. During or after cutting, the polishing module 53 can polish the cut area. This design allows for more efficient integration of cutting and polishing operations, eliminating the need for separate polishing equipment and processes, reducing processing time, and improving overall processing efficiency. The positioning module 6 ensures stability during sheet metal processing, contributing to improved cutting accuracy. The coordination between the adjustment mechanism 4 and the telescopic module 51 allows the cutting mechanism 5 to flexibly adjust its position to adapt to different processing needs, making the entire process smoother and more efficient. This solves the problems of cumbersome processing steps, low efficiency, and compromised processing accuracy that may exist in existing technologies.

[0019] Please refer to Figures 1-5The conveying mechanism 3 includes a side plate 31, which is fixedly installed on the front and rear sides of the top of the conveyor frame 2. A rotating shaft 32 is rotatably connected to both ends of the inner side of the side plate 31. A first motor 33 is fixedly installed at the outer end of one side plate 31. The output end of the first motor 33 passes through the side plate 31 and is fixedly connected to the front end of the rotating shaft 32. Conveyor wheels 34 are fixedly installed at both ends of the outer surface of the rotating shaft 32. A conveyor belt 35 is connected to the outer surface of the conveyor wheels 34. Cut steel plates are placed on top of the conveyor belt 35. Steel plate conveying anti-slip bonding plates 36 are evenly spaced and fixedly connected to the outer surface of the conveyor belt 35 along the direction of the conveyor belt 35. The overall cross-sectional shape of the steel plate conveying anti-slip bonding plates 36 is... Arranged in a T-shape, this device, during operation, utilizes the cooperation of the side plate 31 of the conveying mechanism 3, the rotating shaft 32, the first motor 33, the conveyor wheels 34, the conveyor belt 35, and the steel plate conveying anti-slip bonding plates 36. This allows the cut steel plate to be placed on top of the conveyor belt 35 first, then the first motor 33 is started. The first motor 33 drives the rotating shaft 32 to rotate, which in turn drives the conveyor wheels 34 at both ends to rotate synchronously. The rotation of the conveyor wheels 34 drives the conveyor belt 35 to move in a preset direction, thereby conveying the cut steel plate at the top. Simultaneously, the steel plate conveying anti-slip bonding plates 36, evenly spaced on the conveyor belt 35, have an overall T-shaped cross-section. The T-shaped design significantly increases the contact friction between the conveyor belt and the steel plate being cut, preventing the plate from shifting or sliding during its movement. This ensures stable and precise transport of the plate to subsequent processing stages. The design eliminates the need for manual adjustment during transport, relying on the first motor 33 for automated delivery, reducing errors and labor costs associated with manual intervention. The T-shaped anti-slip bonding plate 36 further enhances transport stability, ensuring precise positioning of the plate during transport. This provides a foundation for accurate subsequent cutting, polishing, and other processing steps, solving the problems of unstable and easily shifted plate transport in existing technologies, which could affect subsequent processing accuracy or require frequent manual adjustments. This makes the entire plate transport process more efficient and reliable.

[0020] Please refer to Figures 1-4 and Figures 6-7The adjusting mechanism 4 includes a concave frame 41, which is fixedly installed on the side of the input end conveyor 2 near another conveyor 2. A top plate 42 is fixedly installed on the top of the concave frame 41, and a transverse moving module 43 is provided on the top of the top plate 42. A telescopic module 51 is fixedly installed on the moving end of the transverse moving module 43. A positioning module 6 is fixedly connected to the front and rear ends of the side of the top plate 42 away from the cutting mechanism 5. The transverse moving module 43 includes a fixed frame 431, which is fixedly installed on the top of the top plate 42. Both ends of the fixed frame 431 are rotatably connected to drive wheels 432, and the outer surfaces of the two drive wheels 432 are connected to a drive belt 433. A second motor 434 is fixedly installed on one end of the fixed frame 431. The output end of 434 is fixedly connected to one side of a drive wheel 432. A guide assembly 435 is fixedly installed on the side of the fixed frame 431 near the cutting mechanism 5. A telescopic module 51 is fixedly connected to the outside of the guide assembly 435. The guide assembly 435 includes a rail frame 4351, which is fixedly installed on the side of the fixed frame 431 near the cutting mechanism 5. A slide plate 4352 is slidably connected inside the rail frame 4351. A fixed arm 4353 is fixedly connected to the top of the slide plate 4352. The outside of the fixed arm 4353 is fixedly connected to the top of the drive belt 433. The telescopic module 51 is fixedly installed on the outside of the slide plate 4352. During the application of this device, it is moved by the concave frame 41, top plate 42, and transverse movement of the adjustment mechanism 4. The cooperation of module 43, guide assembly 435, and positioning module 6 allows the position of the cutting mechanism 5 to be adjusted according to processing requirements during use. After the second motor 434 of the transverse module 43 is started, the second motor 434 will drive the drive wheel 432 at one end of the fixed frame 431 to rotate. When the drive wheel 432 rotates, it drives the drive belt 433 to drive along the two drive wheels 432. The drive belt 433 then drives the slide plate 4352 to slide along the rail frame 4351 of the guide assembly 435 through the fixed arm 4353. The telescopic module 51 is fixed on the outside of the slide plate 4352. The sliding of the slide plate 4352 will drive the telescopic module 51 to move synchronously, thereby realizing the horizontal position adjustment of the cutting mechanism 5. At the same time, the positioning module 6 can be used during processing. The positioning module 5 plays a role in positioning the steel plate being cut, preventing plate misalignment from affecting cutting accuracy. This design allows for more flexible and precise position adjustment of the cutting mechanism 5. Driven by the second motor 434 and guided by the guide component 435, the movement trajectory of the cutting mechanism 5 can be stably controlled, ensuring that the cutting mechanism 5 can accurately align with the part of the plate to be cut, meeting different cutting position requirements. There is no need for manual adjustment of the position of the cutting mechanism 5, reducing errors and labor intensity caused by manual operation. The cooperation of the positioning module 6 further ensures the stability of the processing process, solving the problems of inconvenient adjustment and insufficient positional accuracy of the cutting mechanism 5 in the prior art, which may affect the cutting quality, making the entire cutting position adjustment process more efficient and reliable.

[0021] Please refer to Figures 1-4and Figures 6-7 The telescopic module 51 includes a vertical guide rail 511, which is fixedly installed on the side of the slide plate 4352 away from the fixing frame 431. A mounting base 515 is fixedly connected to the top of the vertical guide rail 511. A third motor 512 is fixedly installed on the top of the mounting base 515. The output end of the third motor 512 passes through the mounting base 515 and the vertical guide rail 511. A ball screw 513 is fixedly installed on the ball screw 513, which is rotatably connected to the inside of the vertical guide rail 511. A movable block 514 is threaded onto the outer surface of the ball screw 513. A connecting arm 54 is fixedly installed on the outside of the movable block 514. An external arm 52 fixing frame 431 is installed on the lower side of one side of the vertical guide rail 511. (Positioning module) The device includes a side mounting frame 61, which is fixedly installed on the outer middle of the side plate 31. A first electric push rod 62 is fixedly installed on the top of the side mounting frame 61. The output end of the first electric push rod 62 passes through the side mounting frame 61 and is fixedly installed with a pressing and positioning frame 63. Positioning pressure rollers 64 are rotatably connected to the inner side of the pressing and positioning frame 63 in a linear arrangement at equal intervals. During the application of this device, through the cooperation of the vertical guide rail 511 of the telescopic module 51, the mounting base 515, the third motor 512, the ball screw 513, the movable block 514, and the side mounting frame 61, the first electric push rod 62, the pressing and positioning frame 63, and the positioning pressure rollers 64 of the positioning module 6, the height of the cutting part can be flexibly adjusted and stabilized during use. After the positioning plate is positioned, the third motor 512 of the telescopic module 51 is activated. The third motor 512 drives the ball screw 513 to rotate inside the vertical guide rail 511. When the ball screw 513 rotates, it drives the movable block 514 to move along the vertical guide rail 511 through thread transmission. The movable block 514 then drives the connecting arm 54 to move synchronously, thereby realizing the adjustment of the height of the outer end component of the connecting arm 54. At the same time, after the first electric push rod 62 of the positioning module 6 is activated, it pushes the pressing positioning frame 63 to move, so that the positioning pressure roller 64 on the inner side of the pressing positioning frame 63 contacts the plate. The positioning pressure roller 64 positions the plate, and the positioning pressure roller 64 can rotate with the plate. This design allows for the cutting of related parts. The height adjustment of the components is more precise and stable. Through the cooperation of the third motor 512 and the ball screw 513, the movement distance of the movable block 514 can be precisely controlled to meet the processing requirements of plates of different thicknesses. The positioning module 6 effectively prevents the plate from shifting during processing by contacting the positioning pressure roller 64 with the plate. At the same time, the rotation of the positioning pressure roller 64 will not hinder the plate conveying. There is no need to manually adjust the height of the components or fix the plate, which reduces the error and labor intensity of manual operation. It solves the problems of inconvenient component height adjustment and unstable plate positioning that may affect the processing accuracy in the existing technology, making the height adjustment and plate positioning of the entire processing process more efficient and reliable, and providing support for precise processing.

[0022] Please refer to Figures 5-8The polishing module 53 includes a mounting arm 531, which is fixedly mounted to the outer end of an external arm 52. The mounting arm 531 is U-shaped. Mounting brackets 532 are fixedly mounted at both the upper and lower ends of the inner side of the mounting arm 531. A polishing assembly 533 is fixedly mounted on the outer side of the mounting brackets 532. The polishing assembly 533 includes a side plate 5331, which is fixedly mounted to the outer end of the mounting brackets 532. A fourth motor 5332 is fixedly mounted on the side of the side plate 5331 near the mounting arm 531.

A hexagonal screw seat 5335 is fixedly mounted on the output end of the fifth motor 5337. The outer side of the hexagonal screw seat 5335 is... The device is bolted with a polishing disc 5336. During operation, the polishing module 53 utilizes a combination of the mounting arm 531, mounting bracket 532, polishing assembly 533, side plate 5331 of the polishing assembly 533, fourth motor 5332, mounting disc 5333, second electric push rod 5334, hexagonal screw seat 5335, and polishing disc 5336 to precisely polish the cut steel plate. When the fourth motor 5332 of the polishing assembly 533 is activated, the fifth motor 5337 drives the mounting disc 5333 to rotate. The mounting disc 5333 then drives the second electric push rod 5334, hexagonal screw seat 5335, and polishing disc 5336 to rotate synchronously, allowing adjustment of the polishing angle. Simultaneously, the second electric push rod 5334 pushes the hexagonal screw seat 5335 and polishing disc 5336 to move back and forth, adjusting the contact position between the polishing disc 5336 and the cut edge of the steel plate. The mounting arm 531 is U-shaped. The shape design allows the mounting brackets 532 and polishing components 533 on the inner upper and lower ends to fit more closely to the upper and lower edges of the steel plate, ensuring that the polishing disc 5336 can fully act on the cutting area. The hexagonal screw seat 5335 installs the polishing disc 5336 with bolts, which also facilitates subsequent replacement according to polishing needs or the wear of the polishing disc 5336. This design allows the polishing operation to flexibly adapt to different positions of the steel plate cutting area. The polishing disc 5336 is rotated by the fifth motor 5337 to achieve polishing. The second electric push rod 5334 adjusts the position to ensure full polishing coverage, avoiding irregular particles or sharp protrusions left on the edge of the steel plate after cutting. No additional special polishing equipment is needed, reducing process changes and eliminating the need for manual polishing, reducing labor intensity and operational errors. It solves the problems of inconvenient polishing and incomplete coverage that may affect the processing quality in existing technologies, making the polishing process after steel plate cutting more efficient and precise, and ensuring the edge quality of the processed steel plate.

[0023] The implementation principle of a steel plate flame cutting machine according to an embodiment of this application is as follows: During the application of this equipment, after starting the device, the steel plate to be cut is first placed on the top of the conveyor belt 35 of the conveying mechanism 3. The steel plate will naturally contact the anti-slip bonding plate 36 on the conveyor belt 35. By setting the anti-slip bonding plate 36, the friction between the plate and the conveyor belt 35 can be increased, making it less likely for the plate to deviate during the conveying process, thus providing initial assurance for the accuracy of subsequent cutting operations. Then, the first motor 33 is started, and the first motor 33 will directly drive the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it drives the conveyor wheel 34 to rotate synchronously. The rotation of the conveyor wheel 34 will drive the conveyor belt 35 to move in a preset direction. During the movement of the conveyor belt 35, the steel plate to be cut is gradually conveyed towards the transfer mechanism 4. During this process, the conveyor frame 2 provides stable support for the conveying mechanism 3 to prevent the conveying mechanism 3 from shaking during operation; while the base frame 1 acts as... The overall support structure of the equipment ensures that all components remain stable during operation, preventing vibration from affecting processing accuracy. When the steel plate is conveyed to the positioning module 6, the first electric push rod 62 of the positioning module 6 is immediately activated. The first electric push rod 62 pushes the pressing positioning frame 63 downward. As the pressing positioning frame 63 moves, it drives the positioning pressure roller 64 downward synchronously until the positioning pressure roller 64 is in close contact with the surface of the steel plate. The positioning pressure roller 64 positions the plate in real time, preventing displacement during subsequent cutting. At the same time, the conveyor belt 35 continues to run, and the positioning pressure roller 64 rolls with the plate, without obstructing the conveying of the plate. The fixed plate provides a stable mounting base for the first electric push rod 62, ensuring that the positioning action can be executed accurately and reliably. Throughout the entire processing, the positioning module 6 maintains the state of pressing and positioning the steel plate, further improving the stability of the cutting process. According to the preset cutting trajectory of the steel plate, the second motor 434 of the transverse module 43 in the adjustment mechanism 4 starts. The second motor 434 drives the drive wheel 432 to rotate. When the drive wheel 432 rotates, it drives the drive belt 433 to move along a fixed path. The movement of the drive belt 433 drives the slide plate 4352 to slide along the rail frame 4351 of the guide component 435 through the fixed arm 4353. During the sliding process of the slide plate 4352, it drives the telescopic module 51 and the flame cutting gun 55 and polishing module 53 associated with the telescopic module 51 to move synchronously in the horizontal direction. Finally, the flame cutting gun 55 is adjusted to the preset cutting starting position. Here, the fixed frame 431 provides the installation base for the drive wheel 432 and the guide component 435, ensuring that the components of the transverse module 43 can be stably assembled; while the rail frame 4351 provides a stable sliding track for the slide plate 4352, so that the slide plate 4352 will not deviate when moving in the horizontal direction, ensuring the accuracy of the horizontal adjustment. Then the extension The third motor 512 of the shrinking module 51 starts, which drives the ball screw 513 to rotate. The ball screw 513 drives the movable block 514 to move up and down along the vertical guide rail 511 through the thread transmission. When the movable block 514 moves, it drives the connecting arm 54 and the flame cutting gun 55 connected to the connecting arm 54 to move up and down synchronously. The operator can adjust the flame cutting gun 55 to a suitable cutting height according to the actual thickness of the steel plate to be cut, so as to ensure that the flame can effectively act on the part of the plate to be cut. The mounting base 515 provides mounting support for the third motor 512 to prevent the third motor 512 from becoming loose during operation. The vertical guide rail 511 provides guidance for the movement of the movable block 514, ensuring that the movable block 514 remains stable when moving in the vertical direction. The external arm 52 is fixed to the lower end of one side of the vertical guide rail 511 at this time, which prepares the structure for the subsequent work of the polishing module 53 and ensures that the polishing module 53 can move synchronously with the cutting mechanism 5. After the flame cutting torch 55 is activated, it generates a high-temperature flame through the combustion of a mixture of combustible gas and oxygen. This high-temperature flame directly acts on the area to be cut in the steel plate, heating it. When the temperature of this area reaches its ignition point, the flame cutting torch 55 sprays a high-pressure oxygen stream. This high-pressure oxygen stream drives the high-temperature metal to undergo violent oxidation and detach from the plate, ultimately forming a cut on the plate. Simultaneously, according to the preset cutting trajectory, the second motor 434 continues to run, driving the flame cutting torch 55 to move horizontally, thus completing the linear cutting operation. After the linear cutting is completed, polishing is performed. After completion, the first motor 33 is started, which drives the conveyor belt 35 to continuously transport the sheet metal, thereby realizing continuous cutting of the sheet metal. The connecting arm 54 plays a connecting role in this process, stably connecting the movable block 514 and the flame cutting gun 55, ensuring that the flame cutting gun 55 can move with the movable block 514 to achieve positional follow, and ensuring that the cutting trajectory always meets the preset requirements without deviation. In the entire processing process, after each cutting operation, the polishing module 53 can be started to process the cutting edge of the steel plate. During the reset process of the flame cutting gun 55 after each polishing, the second motor 434 will drive the drive wheel 43 2. Reverse rotation causes the drive belt 433 to run in reverse. As the drive belt 433 runs in reverse, it drives the flame cutting gun 55 to reset and move to the initial cutting position. During this process, the conveyor mechanism 3 at the output end is activated to move the cut steel plate a certain distance away. Then, the second motor 434 is activated to drive the outer arm 52 to move laterally. During the movement of the outer arm 52, the telescopic module 51 retracts, raising the flame cutting gun 55 upwards to provide sufficient working space for the polishing module 53. At this time, the fifth motor 5337 of the polishing module 53 starts, driving the mounting plate 5333 to rotate. When disc 5333 rotates, it drives polishing disc 5336 to rotate synchronously; at the same time, the second electric push rod 5334 is activated, pushing polishing disc 5336 to move back and forth, so that polishing disc 5336 can flexibly adjust its rotation angle and position, and approach the top and bottom edges of the steel plate before and after cutting, thereby causing the two polishing discs 5336 to stably contact the edge of the cut steel plate. As the cutting mechanism 5 moves as a whole, the rotating polishing disc 5336 grinds and polishes the edge of the cut steel plate, effectively removing irregular melt particles, weld beads and sharp protrusions from the edge. The mounting arm 531 is U-shaped, providing stable support for the mounting frame 532; the mounting frame 532 provides the mounting base for the polishing assembly 533; the side disc 5331 provides mounting support for the fourth motor 5332.The hexagonal screw seat 5335 is connected to the polishing disc 5336 by bolts, which facilitates the subsequent replacement and maintenance of the worn polishing disc 5336. After the cut surface of the cut steel plate is polished, the fourth motor 5332 and the second electric push rod 5334 can be started to continue running, driving the polishing disc 5336 to contact the cut surface of the steel plate to be cut, thereby realizing the polishing process of the cut surface of the steel plate before and after cutting, improving the overall processing quality. After the cutting and polishing operations are completed, the first motor 33 remains running, driving the rotating shaft 32 in conjunction with the conveyor wheel 34 and conveyor belt 35 to move the processed sheet metal towards the equipment output end, ultimately transporting the sheet metal to the designated collection position, completing a full steel plate processing cycle. This technical solution integrates a polishing module 53 into the cutting mechanism 5, allowing polishing to be performed synchronously with the cutting operation. This eliminates the need for a separate polishing structure outside the cutting process, reducing process transitions, shortening the steel plate processing chain, and effectively improving processing efficiency. It solves the problem of cumbersome and inefficient processing caused by the need for an additional polishing structure after cutting in the prior art. Furthermore, the polishing module 53 achieves automated polishing through multiple motor drives, eliminating the need for manual hand-held tools, reducing the labor intensity of operators. The polishing parameters can be uniformly set and adjusted through the equipment control system, ensuring consistent polishing effects on the cutting edges of different batches and specifications of sheet metal, thus solving the problem of... The manual polishing process suffers from high labor intensity and its effectiveness is affected by the operator's skill level. Furthermore, the polishing module 53 is directly integrated into the cutting mechanism 5, eliminating the need for separate dedicated polishing equipment. This not only reduces equipment purchase costs but also eliminates the need for dedicated space for polishing equipment, effectively saving production space and resolving the issue of additional costs and space requirements associated with dedicated polishing equipment in the prior art. The positioning module 6 effectively prevents the sheet material from shifting during cutting, ensuring a consistently accurate cutting trajectory and improving cutting quality. The anti-slip steel plate 36 in the conveying mechanism 3 prevents the sheet material from shifting during transport, ensuring accurate delivery to the cutting and positioning positions, supporting precise subsequent cutting and polishing operations. The coordination between the adjustment mechanism 4 and the telescopic module 51 enables precise horizontal and vertical adjustments to the cutting mechanism 5, allowing the equipment to adapt to the cutting needs of sheets of different sizes and thicknesses, improving its versatility and expanding its application range.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
