Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to an arc cutting device specifically designed for the production of building steel components. Background Technology

[0002] In the field of construction engineering, steel components are widely used in various projects such as bridges, factories, and high-rise buildings due to their advantages of high strength and high stability. In the production process of steel components, the cutting process is one of the core links, and its precision and efficiency directly affect the subsequent processing quality and production progress. Arc cutting, as a highly efficient thermal cutting technology, has become the mainstream cutting method in the current production of steel components due to its fast cutting speed, wide applicability to materials, and relatively low equipment cost. This technology releases high temperatures through an electric arc generated between the electrode and the workpiece, causing localized melting of the metal in the steel component. Simultaneously, an airflow blows the molten metal away, thus achieving cutting and separation, adapting to the cutting needs of steel components of different specifications and shapes.

[0003] However, existing arc cutting equipment for the production of building steel components still has the following defects in practical applications. Since building steel components are mostly thick-walled structures and made of materials such as carbon steel and alloy steel, they are prone to thermal adhesion during arc cutting—that is, the molten metal at the cutting surface is not completely blown away, and after cooling, it re-solidifies, resulting in the cut steel component segment not being completely separated from the main body. This problem not only requires manual secondary processing, increasing labor costs and production cycle, but also may damage the cutting accuracy of the steel component due to improper manual handling; at the same time, manual handling requires close contact with the high-temperature component after cutting, posing safety hazards such as burns and injuries. Furthermore, existing equipment lacks effective monitoring of the component's falling state after cutting, making it impossible to accurately determine whether auxiliary unloading is needed. In addition, the stability of the steel component's conveying and limiting during cutting is insufficient, and the control of the cutting accuracy around the component is poor, further affecting production efficiency and product qualification rate. Therefore, this invention proposes a dedicated arc cutting equipment for the production of building steel components to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a dedicated arc cutting device for the production of building steel components. This device features an elastic striking component positioned at the front end of the arc cutting assembly. This component is specifically designed to elastically strike and knock off steel component segments that remain adhered after cutting. After arc cutting, if the steel component has not completely fallen off due to thermal fusion adhesion, the elastic striking component can intervene promptly to provide auxiliary striking, achieving separation and detachment of the adhered segments without manual intervention. This completely solves the drawback of existing equipment requiring secondary manual processing, reduces labor costs, avoids safety hazards associated with manual handling, and ensures the continuity of the production process.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a special arc cutting equipment for the production of building steel components, comprising a conveying assembly, a surrounding arc cutting assembly, and an elastic striking assembly. The surrounding arc cutting assembly is located at the feeding end of the conveying assembly, and the conveying assembly is used to send the steel component to the inside of the surrounding arc cutting assembly for surrounding arc cutting. The elastic striking assembly is located at the front end of the surrounding arc cutting assembly and is used to elastically strike and knock down the steel component segments that are still stuck together after cutting. A shock-absorbing pad is provided at the lower position of the front end of the surrounding arc cutting assembly, and the shock-absorbing pad is used to support the falling steel component segments.

[0006] An identification plate is provided above the front end of the surrounding electric arc cutting assembly, and an infrared identification probe is provided below the identification plate. The infrared identification probe determines whether the cut steel component segment has fallen off by distance identification and sends the signal to the control terminal. The control terminal combines the signal with the number of surrounding cuts of the surrounding electric arc cutting assembly to determine whether to activate the elastic striking assembly for auxiliary material feeding.

[0007] A further improvement is that the surrounding arc cutting assembly includes a first frame and a second frame. The upper inner side of the first frame has a rotating hinge shaft, and the outer side of the hinge shaft is provided with a rotating arm and a connecting frame. The rotating arm and the connecting frame are connected to each other. One end of the connecting frame is elastically rotatably provided with a hinge frame, and the inner side of the hinge frame is provided with a hammer head.

[0008] A further improvement is that: a side frame is provided on one side of the rear end of the first seat frame, and a first linkage arm is rotatably provided on the side frame.

A fourth linkage arm is connected to one side of the upper sprocket. The rear end of the second linkage arm is hinged to the fourth linkage arm. Base blocks are provided below both ends of the second seat, and limiting rollers are rotatably provided on the inner side of the base blocks. The limiting rollers at both ends are respectively limited to the two ends of the chain.

[0010] A further improvement is made in that: the front end of the hammer head is provided with a soft pad, and the rear end of the hammer head is provided with a hinge seat. A spring rod is hinged on the hinge seat. A rotating rod is rotatably provided at one end of the inner side of the connecting frame. The spring rod moves through the rotating rod. A spring is sleeved on the outer side of the spring rod, and the spring is located between the rotating rod and the hinge seat.

[0011] A further improvement is made in that: the surrounding arc cutting assembly includes a support column, a lifting plate, and an arc cutting head. The lifting plate is slidably disposed at the front end of the support column. A gear ring is rotatably disposed at the front end of the lifting plate. A connecting plate is connected to the inner side of the gear ring. The arc cutting head is located on the connecting plate. A drive gear adapted to the gear ring is rotatably disposed above the front end of the lifting plate. Bearing gears adapted to the gear ring are disposed on both sides below the front end of the lifting plate. Limiting blocks are disposed at the triangular part of the front end of the lifting plate. The three sets of limiting blocks are equally angled and limited to the outer side of the gear ring.

[0012] A further improvement is made in that: a reduction motor is provided above the rear end of the lifting plate, and the output end of the reduction motor is connected to the drive gear. The drive gear is used to drive the gear ring to rotate. The drive gear has a built-in encoder, which is used to calculate the number of rotations of the drive gear. The control terminal calculates the number of rotations of the gear ring based on the number of rotations of the drive gear, thereby obtaining the number of circumferential cutting revolutions around the arc cutting assembly, specifically based on the following formula:

[0013] ,

[0014] Wherein, n2 is the number of cuts around the arc cutting assembly, i.e. the number of rotations of the gear ring; Z1 is the number of teeth of the drive gear, which is an inherent structural parameter of the equipment and is determined by the design and manufacturing specifications of the drive gear; Z2 is the number of teeth of the gear ring, which is an inherent structural parameter of the equipment and is determined by the design and manufacturing specifications of the gear ring; and n1 is the number of rotations of the drive gear, which is obtained by the encoder built into the drive gear.

[0015] A further improvement is that: the front end of the support column is provided with a guide rail, the lifting plate is slidably mounted on the guide rail through a guide block, a first cylinder is provided on one side of the support column, and the output end of the first cylinder is connected to the lifting plate.

[0016] A further improvement is that the conveying assembly includes a bearing plate, a limiting plate, and a moving plate. The limiting plate is located on both sides of the top of the bearing plate, and the moving plate is slidably located on the inner side of the limiting plate. Both ends of the inner side of the moving plate are provided with ear plates, and a drive roller is rotatably provided on the inner side of the ear plates. A conveyor belt is wound around the outer side of the drive roller.

[0017] A further improvement is that a second cylinder is provided at the middle of the outer side of the limiting plate, and the output end of the second cylinder is connected to the moving plate. Guide rods are provided at both ends of the outer side of the moving plate, and the guide rods movably pass through the limiting plate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention features an elastic striking component positioned at the front end of the surrounding arc cutting component. It is specifically designed to elastically strike and knock off steel component segments that remain adhered after cutting. If the steel component has not completely fallen off due to thermal fusion adhesion after arc cutting, the elastic striking component can intervene in time to provide auxiliary striking. This achieves the separation and falling of the adhered segments without manual intervention, completely solving the drawback of existing equipment requiring secondary manual processing, reducing labor costs, avoiding safety hazards caused by manual processing, and ensuring the continuity of the production process.

[0020] 2. The hammer head of this invention adopts an elastic buffer design. The rear end of the hammer head is hinged to a spring rod through a hinge seat. The spring rod moves through the rotating rod inside the connecting frame, and a spring is sleeved on the outside of the spring rod and located between the rotating rod and the hinge seat. This structure enables the hammer head to have elastic buffering performance during the hammering process and facilitates reset. It can effectively buffer the impact force of the hammering and avoid deformation and damage to steel components caused by hard hammering. It ensures the shape integrity and dimensional accuracy of the steel components after cutting and improves the product qualification rate.

[0021] 3. This invention uses an infrared recognition probe under the recognition plate to accurately determine whether the cut steel component segment has fallen off by means of distance recognition, and sends the signal to the control terminal in real time. The control terminal combines the number of rotations collected by the encoder built into the drive gear, calculates the number of rotations of the arc cutting component through a formula, determines whether the set threshold has been reached, and determines whether to activate the elastic striking component based on the two pieces of information. This intelligent design realizes real-time monitoring and precise control of the cutting and unloading status, avoids the ineffective action of the elastic striking component, reduces equipment energy consumption, and improves the automation and reliability of the unloading process.

[0022] 4. The circumferential arc cutting assembly of this invention uses a geared motor to drive a drive gear, which, together with a bearing gear and three sets of equal-angled limiting blocks, provides limiting support for the gear ring. This drives the arc cutting head on the connecting plate to perform a stable circumferential motion, achieving uniform cutting of the steel component around its entire circumference with higher cutting precision. The lifting plate can slide along the guide rail of the support column via a first cylinder, adapting to the cutting needs of steel components of different heights. The conveying assembly limits the steel component on both sides via a limiting plate, and simultaneously uses a second cylinder to drive a moving plate to slide along a guide rod, adjusting the position of the drive roller and the conveyor belt to achieve stable conveying of steel components of different widths, avoiding cutting deviations caused by steel component offset during conveying. The synergistic effect of both components significantly improves the equipment's adaptability to steel components of different specifications, while ensuring cutting precision and production efficiency.

Detailed Implementation

[0029] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0030] Example 1

[0031] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a special arc cutting equipment for the production of building steel components, including a conveying assembly 1, a surrounding arc cutting assembly 2, and an elastic striking assembly 3. The surrounding arc cutting assembly 2 is located at the feeding end of the conveying assembly 1, and the conveying assembly 1 is used to send the steel component to the inside of the surrounding arc cutting assembly 2 for surrounding arc cutting. The elastic striking assembly 3 is located at the front end of the surrounding arc cutting assembly 2 and is used to elastically strike and knock down the steel component segments that are still stuck together after cutting. A shock-absorbing pad 4 is provided at the lower position of the front end of the surrounding arc cutting assembly 2, and the shock-absorbing pad 4 is used to support the falling steel component segments.

[0032] The upper part of the front end of the arc cutting assembly 2 is provided with an identification plate 5, and the lower part of the identification plate 5 is provided with an infrared identification probe 6. The infrared identification probe 6 determines whether the cut steel component segment has fallen off by distance identification and sends the signal to the control terminal. The control terminal combines the signal and the number of arc cutting revolutions of the arc cutting assembly 2 to determine whether to activate the elastic striking assembly 3 for auxiliary material feeding. During production, the conveying component 1 first stably conveys the steel component to be cut to the inside of the surrounding arc cutting component 2, which then performs a full-circumferential arc cut on the steel component. During the cutting process, the control terminal simultaneously counts the number of arc cuts. After the cutting is completed, the infrared recognition probe 6 detects the change in distance between itself and the steel component segment below to determine whether the steel component segment has not fallen off due to thermal adhesion (if the distance remains unchanged, it is determined to be adhered). After the control terminal integrates the "adhesion judgment signal" and the "circumferential cutting circle count met signal" (ensuring that the cutting has been completed), if adhesion is determined, the elastic knocking component 3 is activated; if it is determined that the component has fallen normally, it is not activated. Finally, the steel component segment that falls normally or is knocked off rests on the shock-absorbing pad 4, which can buffer the impact of the fall and prevent damage to the steel component segment.

[0033] The surrounding arc cutting assembly 2 includes a first frame 7 and a second frame 8. The upper inner side of the first frame 7 has a rotating hinge shaft 13, and the outer side of the hinge shaft 13 is provided with a rotating arm 9 and a connecting frame 10. The rotating arm 9 and the connecting frame 10 are connected to each other. One end of the connecting frame 10 is elastically rotatably provided with a hinge frame 11, and the inner side of the hinge frame 11 is provided with a hammer head 12. The first frame 7 and the second frame 8 are the core support structures of the elastic striking component 3. When elastic striking is required, the power mechanism drives the hinge shaft 13 to rotate inside the first frame 7. The hinge shaft 13 simultaneously drives the rotating arm 9 and the connecting frame 10 fixed on its outside to rotate. The connecting frame 10 drives the hammer head 12 to swing in an arc through the hinge frame 11, so that the hammer head 12 is accurately aligned with the steel component segment that may stick after cutting, providing motion trajectory support for the subsequent elastic striking action. The elastic rotational connection between the hinge frame 11 and the connecting frame 10 allows the hammer head 12 to adapt to the placement angle of the steel component segment before striking, so that the hammer head 12 has elastic buffering performance during striking and is also easy to reset. It can effectively buffer the striking impact force and avoid deformation and damage to the steel component caused by hard impact.

[0034] A side frame 14 is provided on one side of the rear end of the first base 7, and a first linkage arm 15 is rotatably mounted on the side frame 14. A second linkage arm 16 is hinged to the first linkage arm 15, and a third linkage arm 17 is connected to one side of the hinge shaft 13. The front end of the second linkage arm 16 is hinged to the third linkage arm 17. The side frame 14 provides a rotational support point for the first linkage arm 15, forming a power transmission link for the elastic striking assembly 3. External power drives the second linkage arm 16 to push and pull based on the fulcrum of the first linkage arm 15. The second linkage arm 16 then drives the third linkage arm 17 to swing through the hinge node with the third linkage arm 17. Finally, the third linkage arm 17 drives the hinge shaft 13 to rotate, realizing the power transmission of "power → linkage arm assembly → hinge shaft 13 → hammer head 12", ensuring that the hammer head 12 obtains stable striking power.

[0035] The upper and lower ends of the inner side of the second base frame 8 are rotatably provided with sprockets 18, and a chain 19 is wound around the outer side of the sprockets 18. A fourth linkage arm 20 is connected to one side of the upper sprocket 18. The rear end of the second linkage arm 16 is hinged to the fourth linkage arm 20. A base block 25 is provided below both ends of the second base frame 8, and a limiting roller 26 is rotatably provided on the inner side of the base block 25. The limiting rollers 26 at both ends are respectively limited to the two ends of the chain 19. The second frame 8 provides mounting support for the sprocket 18 and chain 19, forming a power amplification and stable transmission structure. External power drives the lower sprocket 18 to rotate, which in turn drives the upper sprocket 18 to rotate synchronously through the chain 19. The upper sprocket 18 drives the fourth linkage arm 20 to swing, and the fourth linkage arm 20 drives the second linkage arm 16 to move through the hinge node, completing the further transmission of power. The limiting roller 26 on the base block 25 limits both ends of the chain 19 to prevent the chain 19 from deviating or falling off during the movement, ensuring the meshing stability of the sprocket 18 and the chain 19, thereby ensuring the transmission accuracy of the entire linkage arm assembly and keeping the striking force and trajectory of the hammer head 12 stable.

[0036] The front end of the hammer head 12 is provided with a soft pad, and the rear end of the hammer head 12 is provided with a hinge seat 21. A spring rod 22 is hinged on the hinge seat 21. A rotating rod 23 is rotatably provided on one end of the inner side of the connecting frame 10. The spring rod 22 moves through the rotating rod 23. A spring 24 is sleeved on the outer side of the spring rod 22, and the spring 24 is located between the rotating rod 23 and the hinge seat 21. This structure serves as the core of the elastic buffer for the hammer head 12. When the hammer head 12 contacts and strikes the steel component segment, the steel component segment generates a reaction force on the hammer head 12, causing the hammer head 12 to drive the spring rod 22 to slide backward along the rotating rod 23 via the hinge seat 21. At this time, the spring 24 is compressed and contracted by the rotating rod 23 and the hinge seat 21, converting the impact force into the elastic potential energy of the spring 24, thus buffering the impact force. After the strike is completed, the spring 24 elastically resets, driving the spring rod 22 and the hammer head 12 back to their initial positions. Simultaneously, the soft pad at the front end of the hammer head 12 directly contacts the steel component segment, further buffering the impact force and preventing deformation or damage to the steel component segment caused by hard strikes.

[0037] The surrounding arc cutting assembly 2 includes a support column 27, a lifting plate 28, and an arc cutting head 29. The lifting plate 28 is slidably disposed at the front end of the support column 27. A gear ring 31 is rotatably disposed at the front end of the lifting plate 28. A connecting plate 32 is connected to the inner side of the gear ring 31. The arc cutting head 29 is located on the connecting plate 32. A drive gear 34 adapted to the gear ring 31 is rotatably disposed above the front end of the lifting plate 28. Bearing gears 33 adapted to the gear ring 31 are disposed on both sides below the front end of the lifting plate 28. Limiting blocks 35 are disposed at the triangular part of the front end of the lifting plate 28. The three sets of limiting blocks 35 are equally angled and limited to the outside of the gear ring 31. The support column 27 provides vertical support for the lifting plate 28. The lifting plate 28 can slide along the support column 27 to adjust its height, adapting to the cutting needs of building steel components of different heights and specifications. During cutting, the drive gear 34 rotates and meshes with the gear ring 31, causing the gear ring 31 to rotate at the front end of the lifting plate 28. The bearing gear 33 meshes with the gear ring 31, providing support for the gear ring 31 from below. Together with the three sets of equal-angled limiting blocks 35 at the triangular part of the lifting plate 28 (which restrict the radial displacement of the gear ring 31 from the outside), the gear ring 31 always maintains stable coaxial rotation, avoiding deviation during rotation. The gear ring 31 drives the arc cutting head 29 to perform a full-circumferential motion through the connecting plate 32, ensuring that the arc cutting head 29 performs uniform and precise circumferential cutting on the steel components.

[0038] A reduction motor 36 is provided above the rear end of the lifting plate 28, and the output end of the reduction motor 36 is connected to the drive gear 34. The drive gear 34 is used to drive the gear ring 31 to rotate. The drive gear 34 has a built-in encoder, which is used to calculate the number of rotations of the drive gear 34. The control terminal calculates the number of rotations of the gear ring 31 based on the number of rotations of the drive gear 34, thereby obtaining the number of rotations of the arc cutting assembly 2, specifically based on the following formula:

[0039] ,

[0040] Wherein, n2 is the number of cuts around the arc cutting assembly 2, that is, the number of rotations of the gear ring 31; Z1 is the number of teeth of the drive gear 34, which is an inherent structural parameter of the equipment and is determined by the design and manufacturing specifications of the drive gear 34; Z2 is the number of teeth of the gear ring 31, which is an inherent structural parameter of the equipment and is determined by the design and manufacturing specifications of the gear ring 31; and n1 is the number of rotations of the drive gear 34, which is obtained by the encoder built into the drive gear 34. The geared motor 36 provides stable rotational power to the drive gear 34, and the output speed of the geared motor 36 can be adjusted to adapt to different cutting speed requirements. When the drive gear 34 rotates, the built-in encoder synchronously collects its rotation number n1 in real time and transmits the data to the control terminal. The control terminal calls the preset formula, substitutes the inherent parameters Z1 (number of teeth of drive gear 34) and Z2 (number of teeth of gear ring 31) of the equipment, and calculates the rotation number n2 of gear ring 31. Since the rotation number of gear ring 31 is completely consistent with the number of circumferential cutting circles of the arc cutting head 29, the number of circumferential cutting circles can be accurately obtained, providing core data support for the control terminal to determine whether the cutting is completed.

[0041] The front end of the support column 27 is provided with a guide rail 30, and the lifting plate 28 is slidably mounted on the guide rail 30 via a guide block. A first cylinder 37 is provided on one side of the support column 27, and the output end of the first cylinder 37 is connected to the lifting plate 28. The guide rail 30 provides guiding constraints for the vertical sliding of the lifting plate 28, ensuring that the lifting plate 28 slides smoothly along a fixed trajectory and avoiding deviation during the sliding process that would cause the position of the arc cutting head 29 to deviate. When it is necessary to adjust the cutting height, the control terminal controls the extension and retraction of the first cylinder 37. The output end of the first cylinder 37 pushes or pulls the lifting plate 28, causing the lifting plate 28 to slide up and down along the guide rail 30 via the guide block until the arc cutting head 29 reaches the cutting position adapted to the height of the steel component, thereby realizing the automated and precise adjustment of the cutting height.

[0042] Example 2

[0043] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a special arc cutting equipment for the production of building steel components, including a conveying assembly 1, a surrounding arc cutting assembly 2, and an elastic striking assembly 3. The surrounding arc cutting assembly 2 is located at the feeding end of the conveying assembly 1, and the conveying assembly 1 is used to send the steel component to the inside of the surrounding arc cutting assembly 2 for surrounding arc cutting. The elastic striking assembly 3 is located at the front end of the surrounding arc cutting assembly 2 and is used to elastically strike and knock down the steel component segments that are still stuck together after cutting. A shock-absorbing pad 4 is provided at the lower position of the front end of the surrounding arc cutting assembly 2, and the shock-absorbing pad 4 is used to support the falling steel component segments.

[0044] The upper part of the front end of the arc cutting assembly 2 is provided with an identification plate 5, and the lower part of the identification plate 5 is provided with an infrared identification probe 6. The infrared identification probe 6 determines whether the cut steel component segment has fallen off by distance identification and sends the signal to the control terminal. The control terminal combines the signal and the number of arc cutting revolutions of the arc cutting assembly 2 to determine whether to activate the elastic striking assembly 3 for auxiliary material feeding. During production, the conveying component 1 first stably conveys the steel component to be cut to the inside of the surrounding arc cutting component 2, which then performs a full-circumferential arc cut on the steel component. During the cutting process, the control terminal simultaneously counts the number of arc cuts. After the cutting is completed, the infrared recognition probe 6 detects the change in distance between itself and the steel component segment below to determine whether the steel component segment has not fallen off due to thermal adhesion (if the distance remains unchanged, it is determined to be adhered). After the control terminal integrates the "adhesion judgment signal" and the "circumferential cutting circle count met signal" (ensuring that the cutting has been completed), if adhesion is determined, the elastic knocking component 3 is activated; if it is determined that the component has fallen normally, it is not activated. Finally, the steel component segment that falls normally or is knocked off rests on the shock-absorbing pad 4, which can buffer the impact of the fall and prevent damage to the steel component segment.

[0045] The conveying assembly 1 includes a support plate 38, a limiting plate 39, and a moving plate 40. The limiting plate 39 is located on both sides of the top of the support plate 38. The moving plate 40 is slidably located on the inner side of the limiting plate 39. Both ends of the inner side of the moving plate 40 are provided with ear plates 41, and a drive roller 42 is rotatably provided on the inner side of the ear plates 41. A conveyor belt 43 is wound around the outer side of the drive roller 42. The bearing plate 38 provides bottom support for the entire conveying assembly 1, and the limiting plates 39 on both sides play a lateral limiting role in the conveying direction of the steel components, preventing the steel components from shifting left and right during the conveying process; the ear plate 41 provides rotational support for the drive roller 42, and the external power drives the drive roller 42 to rotate, which drives the conveyor belt 43 to perform cyclical motion. The conveyor belt 43 generates friction when it contacts the steel components, which drives the steel components to move towards the inner side of the arc cutting assembly 2; the moving plate 40 can slide along the inner side of the limiting plate 39, driving the drive roller 42 and the conveyor belt 43 to move synchronously, realizing the adjustment of the spacing of the conveyor belt 43, and adapting to the conveying of steel components of different widths.

[0046] A second cylinder 44 is provided at the middle of the outer side of the limiting plate 39, and the output end of the second cylinder 44 is connected to the moving plate 40. Guide rods 45 are provided at both ends of the outer side of the moving plate 40, and the guide rods 45 movably pass through the limiting plate 39. The second cylinder 44 provides power for the sliding of the moving plate 40. When it is necessary to adjust the spacing of the conveyor belt 43, the control terminal controls the extension and retraction of the second cylinder 44, and the output end of the second cylinder 44 pushes or pulls the moving plate 40. The guide rods 45 guide and stabilize the sliding of the moving plate 40, preventing tilting or deviation during the sliding process of the moving plate 40, ensuring that the moving plate 40 drives the drive roller 42 and the conveyor belt 43 to move smoothly in the lateral direction, accurately adjusting to the spacing suitable for the width of the steel component, ensuring that steel components of different widths can be stably conveyed, and improving the versatility of the equipment.

[0047] This specialized arc cutting equipment for building steel components is equipped with an elastic striking component 3 located at the front end of the arc cutting component 2. It is specifically designed to elastically strike and knock off steel component segments that remain adhered after cutting. After arc cutting, if the steel component has not completely fallen off due to thermal fusion adhesion, the elastic striking component 3 can intervene in time to provide auxiliary striking, achieving the separation and falling of the adhered segments without manual intervention. This completely solves the drawback of existing equipment requiring secondary manual processing, reduces labor costs, avoids safety hazards caused by manual processing, and ensures the continuity of the production process. Furthermore, the hammer head 12 is installed with an elastic buffer design. The rear end of the hammer head 12 is hinged to the spring rod 22 through the hinge seat 21. The spring rod 22 moves through the rotating rod 23 inside the connecting frame 10. A spring 24 is sleeved on the outside of the spring rod 22 and is located between the rotating rod 23 and the hinge seat 21. This structure enables the hammer head 12 to have elastic buffering performance during the hammering process and facilitates reset. It can effectively buffer the impact force of the hammering and avoid deformation and damage to the steel components caused by hard hammering. It ensures the integrity of the shape and dimensional accuracy of the steel components after cutting and improves the product qualification rate. Meanwhile, the present invention uses the infrared recognition probe 6 below the recognition plate 5 to accurately determine whether the cut steel component segment has fallen off by means of distance recognition, and sends the signal to the control terminal in real time. The control terminal combines the number of rotations collected by the encoder built into the drive gear 34, calculates the number of rotations of the arc cutting component 2 through a formula, determines whether the set threshold has been reached, and determines whether to activate the elastic striking component 3 by combining the two pieces of information. This intelligent design realizes real-time monitoring and precise control of the cutting and unloading status, avoids the ineffective action of the elastic striking component 3, reduces equipment energy consumption, and improves the automation and reliability of the unloading process. In addition, the circumferential arc cutting assembly 2 of the present invention drives the drive gear 34 through the reduction motor 36, which, together with the bearing gear 33 and three sets of equal-angled limiting blocks 35, limits and supports the gear ring 31, driving the arc cutting head 29 on the connecting plate 32 to make a stable circumferential motion, thereby achieving uniform cutting of the steel component around the entire circumference and higher cutting accuracy. The lifting plate 28 can slide along the guide rail 30 of the support column 27 through the first cylinder 37 to adapt to the cutting requirements of steel components of different heights. The conveying assembly 1 limits the steel component on both sides through the limiting plate 39, and at the same time, drives the moving plate 40 to slide along the guide rod 45 with the help of the second cylinder 44, adjusting the position of the drive roller 42 and the conveyor belt 43 to achieve stable conveying of steel components of different widths and avoid the steel component shifting during the conveying process, which would cause cutting deviation. The synergistic effect of the two greatly improves the adaptability of the equipment to steel components of different specifications, while ensuring cutting accuracy and production efficiency.
