Description

Technical Field

[0001] This invention belongs to the field of steel structure component processing technology, specifically relating to a steel structure box column production device. Background Technology

[0002] In the production process of box-type columns, the first step is the assembly and welding of the web and the base plate (partition plate), ensuring the accuracy and stability of the web position and providing a solid foundation for subsequent steps. The next stage is the U-shaped assembly, which involves combining two side plates and a base plate to form a U-shaped structure and completing the corresponding welding. However, the U-shaped assembly process presents some challenges in the current production process.

[0003] Traditionally, the U-shaped assembly of box columns relies on horizontal swing arms on both sides to limit and fix the side panels. While this method effectively maintains the positional stability of the side panels, it requires additional space to accommodate the swing arms, significantly increasing the width of the assembly platform and limiting the effective utilization of factory space. To address this issue, existing welding methods typically employ a design where the box column moves while the spot welding device remains stationary, such as the box column spot welding device described in application number CN202221839625.3, which uses a conveyor roller assembly to transport the box column. However, this method, which relies on moving the box column to reach different welding positions, makes it difficult to guarantee the accuracy of the welding position for each U-shaped assembly welding operation. Furthermore, moving large, heavy box columns is not only time-consuming and labor-intensive but also increases energy consumption.

[0004] If we attempt to improve welding accuracy by allowing the welding platform to move freely along the length of the assembly platform, the welding platform would need to be designed to be longer than the assembly platform. This would further occupy valuable factory space and limit the flexibility of the production line layout. Although some innovative solutions have been proposed in existing technical literature, such as the welding production line for box girders described in application number CN202222505701.3, which uses clamping blocks in a clamping device to fix the side plates, effectively reducing the width of the assembly platform and improving space utilization and operational flexibility, this clamping method cannot effectively fix taller side plates when applied to the production of taller box columns due to the height limitation of the clamping blocks. This affects the stability and accuracy of the welding process.

[0005] Although the automatic welding device for double-wire gas shielded welding of box columns described in application number CN201921766495.3 has successfully realized the mobile operation of the welding platform, this technical solution is only applicable to the welding of the corner welds of box columns and not to the assembly welding process of box columns. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide a steel structure box column production device, which aims to solve the problem of the existing technology having a large assembly platform width and being unable to achieve mobile operation of the welding platform during the assembly of box columns by optimizing the two-side swing arm structure in the traditional box column production device.

[0007] To solve the above-mentioned technical problems, the first technical solution of the present invention is a steel structure box column production device, including a clamping component with a swing arm for fixing the box column workpiece. The clamping component has a retracted state and an operating state. An assembly platform is used for the assembly and welding of the box column. The assembly platform has a movable groove for the swing arm to move. In non-U-shaped assembly, the clamping component is in the retracted state, and the swing arm is located below the assembly platform. In U-shaped assembly, the clamping component is in the operating state, and the swing arm extends from the movable groove to limit the position of the box column workpiece.

[0008] Preferably, the operating state is divided into a feeding state and a clamping state; when the clamping component is in the feeding state, there is an inclination angle between the swing arm and the assembly platform, so as to place the box-shaped column workpiece by relying on the swing arm; when the clamping component is in the clamping state, the swing arm and the assembly platform are in a vertical relationship, and the box-shaped column workpiece is clamped and fixed by the swing arm.

[0009] Furthermore, the clamping component also includes a base, on which a guide structure for assembling the swing arm is provided; when the clamping component is in the retracted state, the guiding direction of the guide structure is parallel to the length direction of the swing arm, and by changing the position of the swing arm on the guide structure, the clamping component can switch between the retracted state and the working state; when the clamping component is in the working state, by changing the angle between the swing arm and the guide structure, the clamping component can switch between the material feeding state and the clamping state in the working state.

[0010] Furthermore, the guide structure has a mounting block that can slide on the base, a linear moving component for driving the mounting block, and a limiting surface for restricting the movement of the swing arm. The mounting block and the swing arm are rotatably connected. Under the action of the limiting surface, the linear moving component controls the movement of the mounting block, thereby causing the position of the swing arm to change on the guide structure. The base also has a vertical surface, and the top end of the limiting surface intersects with the vertical surface. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the clamping component switches from a retracted state to a working state. At this time, the swing arm can rotate about the mounting block as the center point towards the vertical surface, realizing the switching of the clamping component between the unloading state and the clamping state in the working state. When the swing arm contacts the vertical surface, the clamping component switches from the unloading state to the clamping state.

[0011] Furthermore, a drive motor is provided on the mounting block, and the output end of the drive motor is connected to the swing arm; when the mounting block reaches the intersection of the limiting surface and the vertical surface, the drive motor drives the swing arm to rotate in the direction of the vertical surface.

[0012] To solve the above-mentioned technical problems, the second technical solution of the present invention is a steel structure box column production device, which provides another swing arm rotation scheme, as follows: The guide structure has a control block that can slide on the base. The control block and the mounting block are both controlled by the linear moving component. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the mounting block is fixed at the intersection, and the control block moves with the moving end of the linear moving component. The base is provided with a push block and a starting block. The push block and the starting block are both located at the intersection of the limiting surface and the vertical surface. The push block is located on the side closer to the limiting surface, and the starting block is located on the side closer to the vertical surface. The base is provided with a control circuit for connecting the push block and the starting block. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the control block pushes the starting block. Under the action of the control circuit, the push block moves, thereby realizing that the push block pushes the swing arm to rotate in the direction of the vertical surface.

[0013] Furthermore, the base is provided with a locking block and an excitation block, the locking block and the excitation block are located between the push block and the start block, the locking block is located on the side closer to the limiting surface, and the excitation block is located on the side closer to the vertical surface; the base is provided with a transmission circuit for connecting the locking block and the excitation block; when the mounting block reaches the junction of the limiting surface and the vertical surface, the control block pushes the start block to excite the block, and under the action of the transmission circuit, the locking block extends, thereby restricting the movement of the mounting block.

[0014] Furthermore, the swing arm includes a sliding member and a swing member, which are slidably connected. The sliding member is rotatably connected to the mounting block, and one end of the swing member is rotatably connected to the junction of the limiting surface and the vertical surface of the base. When the mounting block reaches the junction of the limiting surface and the vertical surface, the control block pushes the starting block. Under the action of the control circuit, the push block is activated, causing the push block to push the swing member to rotate, thereby causing the sliding member to rotate towards the vertical surface.

[0015] To solve the above-mentioned technical problems, the third technical solution of the present invention is a method of using the steel structure box column production device described in the first technical solution, the method comprising the following steps:

[0016] 1) Clamping component state switching: The transition from the retracted state to the working state is achieved by controlling the linear moving component to drive the mounting block to slide along the guide structure until the mounting block reaches the intersection of the limiting surface and the vertical surface, thus completing the transition from the retracted state to the working state; the transition from the unloading state to the clamping state is achieved by driving the swing arm to rotate through the drive motor. When the swing arm is perpendicular to the assembly platform, the transition from the unloading state to the clamping state is completed.

[0017] 2) Box-type column assembly process: During non-U-shaped assembly, the clamping components remain retracted; if the clamping components are not needed to fix the box-type column workpiece, they remain retracted, and the swing arm is located below the assembly platform, not interfering with other operations in box-type column production; during U-shaped assembly, the clamping components remain in the working state; when it is necessary to place the box-type column workpiece, the drive motor drives the swing arm to rotate to a position at an angle to the assembly platform, facilitating workpiece placement; after the box-type column workpiece is placed in place, the drive motor continues to adjust the swing arm to make it perpendicular to the assembly platform, clamping and fixing the box-type column workpiece, ready for assembly or welding operations; after completing the assembly or welding operation, the above steps can be repeated, and the clamping components are readjusted to the retracted state to prepare for the next operation.

[0018] To solve the above-mentioned technical problems, the fourth technical solution of the present invention is a method of using the steel structure box column production device described in the second technical solution, the method comprising the following steps:

[0019] 1) Clamping component state switching: From the retracted state to the working state, the linear moving component drives the mounting block to slide along the guide structure until the mounting block reaches the intersection of the limiting surface and the vertical surface, completing the transition from the retracted state to the working state; from the unloading state to the clamping state, the control block pushes the trigger block, and under the action of the transmission circuit, the clamping block extends to restrict the movement of the mounting block and prevent unnecessary displacement during operation; at the same time, the control block pushes the starter block, and under the action of the control circuit, the pusher block moves, and the action of the pusher block pushes the swing component, causing the swing component to rotate in the direction of the vertical surface with the mounting block as the center point. When the swing arm is perpendicular to the assembly platform, the transition from the unloading state to the clamping state is completed.

[0020] 2) Box-type column assembly process: During non-U-shaped assembly, the clamping components remain retracted. If the clamping components are not needed to fix the box-type column workpiece, they remain retracted, with the swing arm positioned below the assembly platform, not obstructing other box-type column production operations. During U-shaped assembly, the clamping components remain operational. When a box-type column workpiece needs to be placed, the linear moving component moves the control block, pushing the starting block. The control circuit then moves the push block, causing the swing arm to rotate a certain angle towards the vertical plane, creating an inclination angle to facilitate placement of the box-type column workpiece. After placing the workpiece, the moving component continues to push the starting block by moving the control block until the swing arm is perpendicular to the assembly platform, clamping and fixing the workpiece, ready for assembly or welding operations. After completing the assembly or welding operation, the above steps can be repeated, and the clamping components can be readjusted to the retracted state to prepare for the next operation.

[0021] The main technical effects of this invention are reflected in the following aspects:

[0022] By designing a multi-state switching mechanism for the clamping components (including retracted state, working state, unloading state, and clamping state), the production process has been significantly optimized: the retracted state effectively reduces the width of the assembly platform and improves the utilization rate of factory space; the switching between unloading and clamping states in the working state not only facilitates workpiece placement but also ensures high stability and accuracy during the welding process.

[0023] By designing the clamping components to be retracted during non-U-shaped assembly and positioning the swing arm below the assembly platform, this invention significantly reduces the additional space required for the assembly platform. This design not only effectively reduces the overall footprint of the production unit but also improves the space utilization of the factory, making the production line layout more flexible and efficient. Allowing the welding platform to move freely along the length of the assembly platform enables improved welding position accuracy. Compared to traditional methods that rely on moving box-shaped columns, this solution ensures high stability and accuracy during the welding process while reducing energy consumption and manual intervention, thus enhancing the overall operational flexibility and efficiency.

[0024] Introducing a drive motor for arm angle adjustment greatly simplifies the operation process and reduces the need for manual adjustments. Furthermore, the application of automated components ensures consistency and accuracy in every angle adjustment, enhancing system stability and reliability. This improvement not only increases work efficiency but also reduces operational difficulty and error rate. Simultaneously, by replacing the drive motor with a mechanical linkage mechanism consisting of control blocks, start-up blocks, and locking blocks, precise arm angle adjustment and mounting block position locking are achieved. This design not only improves system reliability and safety but also allows for easy switching of the clamping components between various states through the drive of linear moving parts.

Detailed Implementation

[0033] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0034] The steel structure box column production device provided by the present invention is mainly used for the U-shaped assembly of box columns, but it is not limited thereto and can also be used in other similar welding and production processes.

[0035] Example 1

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7This embodiment discloses a steel structure box-shaped column production device, including a clamping component 1 with a swing arm 11 for fixing the box-shaped column workpiece. The clamping component 1 has a retracted state and an operating state. An assembly platform 3 is used for assembling and welding the box-shaped column. The assembly platform 3 has a movable groove 31 for the swing arm 11 to move freely without obstruction. In non-U-shaped assembly, the clamping component 1 is in the retracted state, and the swing arm 11 is located below the assembly platform 3, not occupying additional space. In U-shaped assembly, the clamping component 1 is in the operating state, and the swing arm 11 extends from the movable groove 31, limiting the position of the box-shaped column workpiece. This significantly reduces the width required for the assembly platform 3 and improves the utilization rate of factory space. Compared to previous methods that relied on moving box columns to achieve different welding positions, this solution allows the welding platform to move flexibly along the length of the assembly platform 3, while maintaining good maneuverability for large and heavy box columns, thereby achieving higher welding accuracy and operational flexibility.

[0037] See Figure 3 and Figure 4 The operation is divided into a feeding state and a clamping state. When the clamping component 1 is in the feeding state, there is an inclination angle between the swing arm 11 and the assembly platform 3, which facilitates the placement of the box-shaped column workpiece by relying on the swing arm 11, reducing the time and effort required for manual adjustment and improving work efficiency. When the clamping component is in the clamping state, the swing arm 11 and the assembly platform 3 are in a vertical relationship, and the box-shaped column workpiece is clamped and fixed by the swing arm 11, ensuring that the box-shaped column can maintain high stability during the welding process and guaranteeing the welding quality.

[0038] See Figure 5 The clamping component 1 further includes a base 12, on which a guide structure 13 for assembling the swing arm 11 is provided. When the clamping component 1 is in the retracted state, the guiding direction of the guide structure 13 is parallel to the length direction of the swing arm 11. By changing the position of the swing arm 11 on the guide structure 13, the clamping component 1 can switch between the retracted state and the working state. When the clamping component 1 is in the working state, by changing the angle between the swing arm 11 and the guide structure 13, the clamping component 1 can switch between the material feeding state and the clamping state in the working state.

[0039] See Figure 5The guide structure 13 has a mounting block 14 that can slide on the base 12, a linear moving component 15 for driving the mounting block 14, and a limiting surface 16 for restricting the movement of the swing arm 11. The mounting block 14 and the swing arm 11 are rotatably connected, allowing the swing arm 11 to rotate about the mounting block 14 as the center point. The design of the limiting surface 16 ensures the stability and accuracy of the swing arm 11 in any state, especially during the process of switching from the unloading state to the clamping state, ensuring the safe fixation of the box-shaped column workpiece and improving the welding quality. Under the action of the limiting surface 16, the linear moving component 15 controls the movement of the mounting block 14, thereby causing the position of the swing arm 11 on the guide structure 13 to change. The base 12 also has a vertical surface 17, and the top of the limiting surface 16 intersects with the vertical surface 17. When the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, the clamping component 1 switches from the retracted state to the working state. At this time, the swing arm 11 can rotate about the mounting block 14 as the center point towards the vertical surface 17, realizing the switching between the feeding state and the clamping state of the clamping component 1 in the working state. When the swing arm 11 contacts the vertical surface 17, the clamping component 1 switches from the feeding state to the clamping state. By introducing the adjustable guide structure 13 and the angle adjustment mechanism of the swing arm 11, not only is the flexible switching between the retracted state and the working state of the clamping component 1 realized, but it can also adapt to different production needs and box column sizes.

[0040] A drive motor is mounted on the mounting block 14, and the output end of the drive motor is connected to the swing arm 11. When the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, the drive motor drives the swing arm 11 to rotate towards the vertical surface 17. With the help of the drive motor, the swing arm 11 can accurately complete the transition from the unloading state to the clamping state; this not only improves the automation level of the operation and reduces the need for manual intervention, but also ensures the consistency and accuracy of each angle adjustment, enhancing the stability and reliability of the entire system.

[0041] Example 2

[0042] This embodiment discloses a steel structure box column production device. Compared with the production device in Embodiment 1, this embodiment provides a new control scheme for switching the clamping component 1 between the retracted state and the working state, as follows:

[0043] See Figure 5 and Figure 6The guide structure 13 has a control block 18 that can slide on the base 12. The control block 18 and the mounting block 14 are both controlled to move by the linear moving component 15. The moving ends of the control block 18, the mounting block 14 and the linear moving component 15 are magnetically or snap-fitted together so that the control block 18 and the mounting block 14 can be separated at the intersection of the limiting surface 16 and the vertical surface 17. When the mounting block 14 reaches the junction of the limiting surface 16 and the vertical surface 17, the mounting block 14 is fixed at the junction, and the control block 18 moves with the moving end of the linear moving component 15. The base 12 is provided with a push block 19 and a start block 20. The push block 19 and the start block 20 are both located at the junction of the limiting surface 16 and the vertical surface 17. The push block 19 is located on the side closer to the limiting surface 16, and the start block 20 is located on the side closer to the vertical surface 17. The base 12 is provided with a control circuit 21 for connecting the push block 19 and the start block 20. When the mounting block 14 reaches the junction of the limiting surface 16 and the vertical surface 17, the control block 18 pushes the start block 20. Under the action of the control circuit 21, the push block 19 is activated, thereby enabling the push block 19 to push the swing arm 11 to rotate towards the vertical surface 17.

[0044] See Figure 6 The base 12 is provided with a locking block 22 and an excitation block 23. The locking block 22 and the excitation block 23 are located between the push block 19 and the start block 20. The locking block 22 is located on the side closer to the limiting surface 16, and the excitation block 23 is located on the side closer to the vertical surface 17. The base 12 is provided with a transmission circuit 24 for connecting the locking block 22 and the excitation block 23. When the mounting block 14 reaches the junction of the limiting surface 16 and the vertical surface 17, the control block 18 pushes the start block 20 to excite the block 23. Under the action of the transmission circuit 24, the locking block 22 extends, thereby restricting the movement of the mounting block 14.

[0045] See Figure 6The swing arm 11 includes a sliding member and a swing member, which are slidably connected. The sliding member is rotatably connected to the mounting block 14, and one end of the swing member is rotatably connected to the junction of the limiting surface 16 and the vertical surface 17 of the base 12. When the mounting block 14 reaches the junction of the limiting surface 16 and the vertical surface 17, the control block 18 pushes the starting block 20. Under the action of the control circuit 21, the push block 19 is activated, causing the push block 19 to push the swing member to rotate, thereby causing the sliding member to rotate towards the vertical surface 17. The length of rotation of the swing arm 11 optimizes the effect of the push block 19 pushing the swing arm 11 to rotate. Specifically, when it is necessary to adjust the angle of the swing arm 11 (e.g., switching from the feeding state to the clamping state), the push block 19 will act on the swing member. Due to the sliding connection between the sliding member and the swing member, the actual force on the swing arm 11 can be adjusted according to the point and direction of force application. This method actually applies the lever principle, that is, by changing the length of the lever arm, the required force can be adjusted, thus enabling a smaller force to produce a larger rotational effect, effectively reducing energy consumption and improving operational efficiency. By introducing two mechanisms—the push block 19 and the starting block 20, and the locking block 22 and the triggering block 23—not only is precise angle adjustment of the swing arm 11 achieved, but the stability of the mounting block 14 in critical positions is also ensured, improving the reliability and safety of the entire system. Furthermore, by utilizing the linear moving component 15 in conjunction with the control circuit 21 and the transmission circuit 24, a series of automated operation steps are realized, including the angle adjustment of the swing arm 11 and the position locking of the mounting block 14, reducing the need for manual intervention and improving work efficiency.

[0046] Example 3

[0047] This embodiment discloses a method for using the steel structure box column production device described in Embodiment 1, the method comprising the following steps:

[0048] 1) Switching of clamping component 1 state: The transition from the retracted state to the working state is achieved by controlling the linear moving component 15 to drive the mounting block 14 to slide along the guide structure 13 until the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, thus completing the transition from the retracted state to the working state; the transition from the unloading state to the clamping state is achieved by driving the swing arm 11 to rotate through the drive motor. When the swing arm 11 is perpendicular to the assembly platform 3, the transition from the unloading state to the clamping state is completed.

[0049] 2) Box-shaped column assembly process: During non-U-shaped assembly, clamping component 1 remains in the retracted state; when clamping component 1 is not needed to fix the box-shaped column workpiece, it remains in the retracted state, and the swing arm 11 is located below the assembly platform 3, which does not hinder other operations in the production of box-shaped columns; during U-shaped assembly, clamping component 1 remains in the working state; when it is necessary to place the box-shaped column workpiece, the drive motor drives the swing arm 11 to rotate to a position at an inclined angle with the assembly platform 3 to facilitate workpiece placement; after the box-shaped column workpiece is placed in place, the drive motor continues to adjust the swing arm 11 to make the swing arm 11 perpendicular to the assembly platform 3, clamping and fixing the box-shaped column workpiece, ready for assembly or welding operations; after completing the assembly or welding operations, the above steps can be repeated, and the clamping component 1 is readjusted to the retracted state to prepare for the next operation.

[0050] This embodiment provides a relatively direct method for switching the state of the clamping component 1, which mainly relies on the coordinated work of the linear moving component 15 and the drive motor, simplifying the operation process and making it suitable for production environments that require high efficiency and fast response.

[0051] Example 4

[0052] This embodiment discloses a method of using the steel structure box column production device described in Embodiment 2, the method comprising the following steps:

[0053] 1) Switching of clamping component 1 state: From the retracted state to the working state, the linear moving component 15 drives the mounting block 14 to slide along the guide structure 13 until the mounting block 14 reaches the intersection of the limiting surface 16 and the vertical surface 17, thus completing the transition from the retracted state to the working state; From the unloading state to the clamping state, the control block 18 pushes the trigger block 23. Under the action of the transmission circuit 24, the locking block 22 extends to restrict the movement of the mounting block 14, preventing unnecessary displacement during operation; At the same time, the control block 18 pushes the starting block 20, which, under the action of the control circuit 21, causes the push block 19 to move. The movement of the push block 19 pushes the swing component, causing the swing component to rotate towards the vertical surface 17 with the mounting block 14 as the center point. When the swing arm 11 is perpendicular to the assembly platform 3, the transition from the unloading state to the clamping state is completed.

[0054] 2) Box-shaped column assembly process: During non-U-shaped assembly, clamping component 1 remains in the retracted state; when clamping component 1 is not needed to fix the box-shaped column workpiece, it remains in the retracted state, and the swing arm 11 is located below the assembly platform 3, which does not hinder other operations of box-shaped column production; during U-shaped assembly, clamping component 1 remains in the working state; when it is necessary to place the box-shaped column workpiece, the linear moving component 15 moves the control block 18 to push the starting block 20, and the control circuit 21 causes the push block 19 to move, so that the swing arm 11 rotates a certain angle towards the vertical plane 17 to form an inclination angle, which facilitates the placement of the box-shaped column workpiece; after the box-shaped column workpiece is placed in place, the moving component continues to push the starting block 20 by moving the control block 18 until the swing arm 11 is perpendicular to the assembly platform 3, clamping and fixing the box-shaped column workpiece, ready for assembly or welding operations; after the assembly or welding operation is completed, the above steps can be repeated, and the clamping component 1 is readjusted to the retracted state to prepare for the next operation.

[0055] This embodiment introduces a more complex mechanical linkage mechanism (such as control block 18, start block 20, card block 22, etc.), which increases the complexity of the system but provides higher stability and accuracy. Furthermore, the switching of the clamping component 1 between various states can be achieved directly through the drive of the linear moving component 15.

[0056] Furthermore, as is common knowledge in this industry, this production device, in addition to the assembly platform 3 mentioned above, also includes a welding platform. The assembly platform 3, welding platform, linear moving component 15, and drive motor are also mentioned above. Additionally, both the transmission circuit 24 and the control circuit 21 can be hydraulic circuits filled with liquid, and both the starting block 20 and the actuating block 23 are equipped with springs to control their own reset. Since this is common knowledge, its principles and structure will not be described in detail here.

[0057] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

When the clamping component is in the retracted state, the guiding direction of the guide structure is parallel to the length direction of the swing arm. By changing the position of the swing arm on the guide structure, the clamping component can switch between the retracted state and the working state. When the clamping component is in the working state, by changing the angle between the swing arm and the guide structure, the clamping component can switch between the material feeding state and the clamping state in the working state. The guide structure has a mounting block that can slide on the base, a linear moving component for driving the mounting block, and a limiting surface for restricting the movement of the swing arm. The mounting block and the swing arm are rotatably connected. Under the action of the limiting surface, the linear moving component controls the movement of the mounting block, thereby causing the position of the swing arm to change on the guide structure. The base also has a vertical surface, and the top end of the limiting surface intersects with the vertical surface. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the clamping component switches from a retracted state to an operating state. At this time, the swing arm can rotate about the mounting block as the center point towards the vertical plane, so as to realize the switching between the material feeding state and the clamping state of the clamping component in the working state; when the swing arm contacts the vertical plane, the clamping component switches from the material feeding state to the clamping state. The guide structure has a control block that can slide on the base. Both the control block and the mounting block are controlled by the linear moving component. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the mounting block is fixed at the intersection, and the control block moves with the moving end of the linear moving component. The base is provided with a push block and a start block. Both the push block and the start block are located at the intersection of the limiting surface and the vertical surface. The push block is located on the side closer to the limiting surface, and the start block is located on the side closer to the vertical surface. The base is provided with a control circuit for connecting the push block and the start block. When the mounting block reaches the intersection of the limiting surface and the vertical surface, the control block pushes the start block. Under the action of the control circuit, the push block moves, thereby enabling the push block to push the swing arm to rotate towards the vertical surface.

2. The steel structure box column production device as described in claim 1, characterized in that: The base is provided with a locking block and an excitation block, which are located between the push block and the start block. The locking block is located on the side closer to the limiting surface, and the excitation block is located on the side closer to the vertical surface. The base is provided with a transmission circuit for connecting the locking block and the excitation block. When the mounting block reaches the junction of the limiting surface and the vertical surface, the control block pushes the start block and the excitation block. Under the action of the transmission circuit, the locking block extends, thereby restricting the movement of the mounting block.

3. The steel structure box column production device as described in claim 2, characterized in that: The swing arm includes a sliding member and a swing member, which are slidably connected. The sliding member is rotatably connected to the mounting block, and one end of the swing member is rotatably connected to the junction of the limiting surface and the vertical surface of the base. When the mounting block reaches the junction of the limiting surface and the vertical surface, the control block pushes the starting block. Under the action of the control circuit, the push block is activated, which pushes the swing member to rotate, thereby causing the sliding member to rotate towards the vertical surface.

4. A method of using the steel structure box column production device as described in claim 3, characterized in that: The method of use includes the following steps: 1) Clamping component state switching: The transition from the retracted state to the working state is achieved by controlling the linear moving component to drive the mounting block to slide along the guide structure until the mounting block reaches the intersection of the limiting surface and the vertical surface, thus completing the transition from the retracted state to the working state. The transition from the unloading state to the clamping state is achieved by the control block pushing the trigger block. Under the action of the transmission circuit, the clamping block extends to restrict the movement of the mounting block, preventing unnecessary displacement during operation. At the same time, the control block pushes the starting block, which, under the action of the control circuit, causes the push block to move. The movement of the push block pushes the swinging component, causing it to rotate around the mounting block in the direction of the vertical plane. When the swing arm is perpendicular to the assembly platform, the transition from the unloading state to the clamping state is completed. 2) Assembly process of box-type columns: When performing non-U-shaped assembly, the clamping components remain in the retracted state; if the clamping components are not required to fix the box-shaped column workpiece, the clamping components remain in the retracted state, and the swing arm is located below the assembly platform, which does not interfere with other operations in the production of box-shaped columns; During U-shaped assembly, the clamping components remain in operation. When it is necessary to place the box-shaped column workpiece, the linear moving component drives the control block to move, thereby pushing the starting block. Through the control circuit, the push block moves, causing the swing arm to rotate a certain angle towards the vertical plane, forming an inclination angle to facilitate the placement of the box-shaped column workpiece. After the box-shaped column workpiece is placed in place, the moving component continues to push the starting block by moving the control block until the swing arm is perpendicular to the assembly platform, clamping and fixing the box-shaped column workpiece, ready for assembly or welding operations. After completing the assembly or welding operation, the above steps can be repeated to readjust the clamping parts to the retracted state in preparation for the next operation.
