Description

Technical Field

[0001] The present application relates to the technical field of bending machines, and in particular to a continuous forming bending machine for H-beams. Background Art

[0002] In the field of steel structure processing, H-shaped steel, as a common structural material, is widely used in many industries such as construction, bridges, and machinery manufacturing. The continuous forming and bending of H-shaped steel is an important process in the processing, and its quality directly affects the stability and performance of the entire steel structure.

[0003] JP2007185672A discloses an H-beam bending processing device, comprising a bending device for bending an H-beam to be bent into a state where one flange is located on the outer diameter side and the other flange is located on the inner diameter side, and a telescopic support structure arranged between the flanges at the bending processing position of the H-beam and used to clamp the web; when the H-beam is bent along the width direction of the web, the device can disperse the bending load acting on the web to prevent the web from buckling, while ensuring that the welding part of the flange will not break, and can easily remove the parts used to prevent the web from buckling after the bending process; when the continuous forming operation of the H-beam is performed, it is necessary to arrange multiple telescopic support structures, hydraulic cylinders or jacks on both sides of the web to prevent the web from bending in the vertical direction during the bending process of the H-beam, but this solution can only perform bending operations along the parallel plane of the web of the H-beam, and is not suitable for bending operations in the direction perpendicular to the web plane;

[0004] CN102896480B discloses a method for manufacturing a hyperbolic H-shaped steel, comprising the following steps: 1) re-inspecting the material of the horizontal plate, flattening the horizontal plate, and pre-treating; 2) computer three-dimensional lofting and plane unfolding; 3) cutting and blanking on a CNC cutting machine; 4) butt welding after beveling the web of the H-shaped steel; 5) marking bending lines and assembly lines on the web and flange plates; 6) manufacturing a bending frame according to three-dimensional coordinates; 7) bending the web and flange plates by a flame correction assisted cold bending forming method; 8) manufacturing an assembly frame; 9) assembling the upper and lower flange plates on the assembly frame respectively, positioning and spot welding; 10) welding the weld between the web and the lower flange plate; 11) hoisting the component out of the frame and turning it over Weld the weld between the web and the upper flange plate; 12) Return to the tire for re-inspection, and use a total station to perform three-dimensional coordinate detection; the present invention uses simple equipment and improves manufacturing efficiency and production efficiency; it adopts a method of flame correction plus external force assistance to achieve the bending and forming of the workpiece, but the bending deformation value needs to be measured before flame correction, and the flame correction position is determined according to the required deformation. At the same time, it is also necessary to determine the size of the counterweight and external force, and mark the heating area on the component to determine the number of heating zones, and after each heating, it is necessary to wait for natural cooling to room temperature and then measure the deformation size to determine the next heating area, so that the H-shaped steel is limited by the flame correction process during the bending process in the direction perpendicular to the web plane, and continuous bending and forming operations cannot be achieved. Summary of the invention

[0005] The problem to be solved by the present application is that when the existing bending machine uses external force to bend the H-beam along the vertical web plane, it is necessary to use flame to heat and correct the deformed parts of the H-beam one by one, and cumbersome measurements and time-consuming natural cooling operations are required before and after heating, which makes it impossible to achieve continuous bending and forming operations of the H-beam.

[0006] In order to solve the above technical problems, the present application provides a continuous forming bending machine for H-beams, comprising a machine base, wherein a platform is symmetrically and fixedly arranged on both sides of the upper width direction of the machine base, a first motor for providing driving force is arranged vertically downward on the top of the platform, and a frame is arranged linearly and reciprocatingly along its surface at the midline position of the upper width direction of the machine base, and a traction assembly capable of pulling the H-beam for reciprocating movement is arranged inside the platform, and the traction assembly comprises a core rod, which is vertically arranged inside the platform and connected to the core rod at both ends by bearings, and support plates threadedly connected to the core rod are arranged at intervals on the upper part of the core rod along its axial direction, and the two support plates are respectively threadedly connected to the core rod, and the two support plates are abutted against one side of the web of the H-beam, and the support plates are threadedly connected to the core rod to adjust the spacing between the flange plates for supporting the H-beam, so that the flange plates of H-beams of various models and sizes can be supported in the vertical direction, thereby ensuring that the H-beam will not slip during the traction process.

[0007] According to the above technical solution, the traction assembly also includes a tray, which is symmetrically arranged on the outside of the support plate and threadedly connected to the core rod. The tray and the support plate are parallel and spaced apart. The two trays are respectively abutted against the end faces of the two flange plates in the height direction, and the support plate and the tray are abutted against the end face of a single flange plate in the thickness direction. The support plate and the tray are both mirror-symmetrical and have a semicircular disk structure connected by bolts and nuts. The tray adjusts the spacing between the support plate and the core rod for clamping the H-beam flange plate, thereby being able to perform vertical clamping operations on the flange plates of H-beams of various models and sizes, thereby ensuring that the H-beam will not bend longitudinally during the traction process.

[0008] According to the above technical solution, the diameter of the pallet is 1.4-1.5 times the diameter of the support plate. By virtue of the size difference between the pallet and the support plate, the flange plate of the H-beam can be placed between the pallet and the support plate, and the web of the H-beam can abut against the support plate, thereby increasing the contact area between the support plate, the pallet and the H-beam, thereby enhancing the friction force used to pull the H-beam to move.

[0009] According to the above technical solution, a bending assembly capable of driving the H-beam to perform bending operations is arranged inside the frame. The bending assembly has the same structure as the traction assembly, including a core rod, a support plate and a tray, which are arranged inside the frame. A jack vertically connected to the core rod is arranged on the outside of the frame. The first slide rails arranged on the surface of the machine base and along the movement direction of the frame are symmetrically arranged on both sides of the width direction of the frame. The first sliders connected to the first slide rails are symmetrically and spaced around the bottom of the frame, so that the jack drives the bending assembly to perform linear reciprocating motion along the surface of the machine base, thereby enabling the H-beam to achieve continuous bending and forming operations under the action of the bending assembly.

[0010] According to the above technical solution, a side support assembly is arranged at the lower end of the interior of the frame, and the side support assembly includes a support plate. There are two support plates, which are spaced and arranged in parallel along the vertical direction. One end of the support plate is symmetrically provided with rollers abutting against the other side of the H-beam web. The support plates are connected by a plurality of vertically arranged support rods. The rollers and support plates are arranged on both sides of the H-beam web, so that the H-beam can be subjected to a restraining force from the horizontal direction during the traction and bending process, thereby preventing the H-beam from escaping from between the support plate and the pallet, thereby ensuring effective traction and anti-slip operation.

[0011] According to the above technical solution, the side support assembly also includes a first screw rod, which is vertically arranged on one side of the support plate, and a first screw sleeve connected to the support rod is threadedly connected to the upper part of the first screw rod, and a vertical plate is vertically arranged on one side of the first screw rod, and bearing seats for supporting the first screw rod are symmetrically arranged at both ends of the vertical plate, and a second motor connected to the first screw rod through a coupling is arranged at one end of the vertical plate, and second slide rails arranged along the movement direction of the first screw sleeve are symmetrically arranged on both sides of the vertical plate, and second sliders connected to the second slide rails are symmetrically and spaced apart on one side of the support rod. Through the action of the second motor, the first screw and the first screw sleeve, the roller can perform longitudinal height adjustment operation according to H-shaped steel of different height sizes, so that the roller can apply force to the centerline position of the web of the H-shaped steel as much as possible, so that the web is relatively evenly stressed.

[0012] According to the above technical solution, the side support assembly also includes a cross plate, which is placed horizontally below the vertical plate and connected to the stand, a second screw is arranged at the upper part of the cross plate along the midline position of its length direction, and the upper part of the second screw is threadedly connected to a second screw sleeve connected to the vertical plate, and both ends of the second screw are connected to the cross plate through bearing seats respectively, and a third motor connected to the second screw through a coupling is arranged at one end of the cross plate, and third slide rails arranged along the movement direction of the second screw sleeve are symmetrically arranged on both sides of the cross plate, and third sliders connected to the third slide rails are symmetrically and spaced apart at the bottom of the vertical plate, and through the action of the third motor, the second screw and the second screw sleeve, the roller can perform horizontal spacing adjustment operations according to H-shaped steel of different thicknesses, so that the roller can fully and effectively abut and limit the H-shaped steel webs of different thicknesses.

[0013] According to the above technical solution, the core rod is evenly and spacedly arranged with keyways along its axial direction in the circumferential direction, the tray is divided into a base plate at the lower end of the core rod and a pressure plate at the upper end of the core rod, the base plate and the core rod are connected by a keyway, the base plate abuts against a bearing seat with an end cover at the bottom of the core rod, the pressure plate and the core rod are also connected by a keyway, the base plate and the pressure plate are connected by the keyway with the core rod, which not only simplifies the loading and unloading method, but also makes the base plate inside the traction assembly and the bending assembly automatically maintain at the same horizontal height after installation, ensuring that there will be no movement interference with the base plate during the traction and bending process of the H-beam.

[0014] According to the above technical solution, the top of the platform is evenly and spacedly arranged along its circumference with downward pressure components for applying vertical pressure to the pressure plate, the downward pressure component includes a cylinder body, the cylinder body is horizontally arranged on the inner side of the top of the platform, a cylinder rod is arranged inside the cylinder body along its axial direction for reciprocating sliding, the end of the cylinder body has a support sleeve arranged with the cylinder rod, a ball head is arranged at one end of the support sleeve, the end of the ball head has a ring that rotates around the support sleeve, the ring is meshed with the cylinder rod, and through the arrangement of the cylinder rod, the pressure plate can apply sufficient downward pressure to the flange plate of the H-shaped steel in the vertical direction to ensure that the H-shaped steel will not undergo vertical bending deformation during the bending process.

[0015] According to the above technical solution, the support plate is divided into an outer plate, a middle plate and an inner plate which are coaxially sleeved in multiple stages. The outer plate, the middle plate and the inner plate are connected in sequence by bolts, so that flange plates of H-shaped steels of different widths can be placed between the support plate and the tray to ensure that the support plate can form a stable contact with the web of the H-shaped steel.

[0016] The present application provides a continuous forming bending machine for H-beam, which has the following beneficial effects:

[0017] The present application sets a traction assembly so that the support plate and the tray can adjust the traction and clamping spacing of the H-shaped steel by means of the threaded connection between the support plate and the core rod, and then the first motor drives the support plate and the tray meshing with the core rod to drive the H-shaped steel between them to perform traction movement, thereby realizing the clamping and traction operation of various types of H-shaped steels;

[0018] 2. The present application sets a bending assembly so that the jack-driven frame and the bending assembly inside it perform bending operations in a direction perpendicular to the plane of the H-beam web, and with the help of the traction of two sets of traction assemblies, the H-beam can achieve continuous bending operations in a moving state, and the bending assembly can also slide along the surface of the first slide rail with the help of the first slider to improve the stability of the motion trajectory during the bending process;

[0019] 3. The application sets the side support assembly so that the roller can be driven by the second motor and the third motor to adjust the horizontal and vertical positions in the space, thereby forming a relatively centered stable support operation for the other side of the web of different types of H-beams, thereby cooperating with the support plate to achieve an effective lateral clamping and supporting operation for the web of the H-beam in the bending process;

[0020] 4. The present application sets a downward pressure assembly so that the cylinder rod can drive the ball head to perform vertical spatial flipping with the help of the sleeve ring engaged with it, thereby applying vertical downward pressure to the pressure plate at the bottom, so that the pressure plate can be effectively pressed on the surface of the upper flange plate of the H-beam, thereby cooperating with the base plate to achieve effective longitudinal clamping and supporting operation on the position of the H-beam flange plate in the bending;

[0021] 5. The present application adopts the setting of a multi-stage sleeve support plate, so that the flange plates of H-shaped steels of different widths can be placed between the support plate and the tray, so as to ensure that the support plate can form a stable contact with the web of the H-shaped steel.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0046] The present application relates to a continuous forming bending machine for H-beams, such as Figure 1-8 As shown, the bending machine includes a machine base 1, and a stand 2 is symmetrically and fixedly arranged on both sides of the upper width direction of the machine base 1. A first motor 3 for providing driving force is arranged vertically downward on the top of the stand 2, and a frame 4 is arranged linearly reciprocatingly along its surface at the midline position of the upper width direction of the machine base 1. A traction assembly 5 capable of pulling the H-shaped steel for reciprocating movement is arranged inside the stand 2. The traction assembly 5 includes a core rod 51, which is vertically arranged inside the stand 2 and connected to the upper and lower ends through bearings. The upper end of the core rod 51 is connected to the first motor 3 through a coupling, and support plates 52 threadedly connected to the core rod 51 are arranged at intervals on the upper part of the core rod 51 along its axial direction. The two support plates 52 are respectively threadedly connected to the core rod 51, and the distance between the two support plates 52 can be conveniently adjusted. The distance between the outer surfaces of the two support plates 52 is the distance between the inner surfaces of the two flange plates of the H-shaped steel, so as to support the two flange plates of the H-shaped steel with different heights.

[0047] The traction assembly 5 also includes a tray 53, which is symmetrically arranged on the outer side of the support plate 52 and is threadedly connected to the core rod 51. The tray 53 and the support plate 52 are parallel and spaced apart. The spacing between the two trays 53 is the thickness of the H-beam flange plate. The spacing between the inner surfaces of the two trays 53 is the overall height of the H-beam, and the diameter of the tray 53 is 1.4-1.5 times the diameter of the support plate 52, so that the two support plates 52 can abut against the web plate, and the two trays 53 abut against the end faces of the two flange plates in the height direction respectively, and the support plate 52 and the tray 53 abut against the end face of a single flange plate in the thickness direction, so as to increase the abutment area with the H-beam and then increase the friction between them, so as to avoid the H-beam from slipping during the traction process. In order to facilitate the independent maintenance and replacement of the support plate 52 and the tray 53, the support plate 52 and the tray 53 are both mirror-symmetrical and have a semicircular disk structure connected by bolts and nuts.

[0048] The frame 4 is provided with a bending assembly 6 capable of driving the H-shaped steel to perform bending operations. The bending assembly 6 has the same structure as the traction assembly 5, including a core rod 51, a support plate 52 and a tray 53, which are arranged inside the frame 4. During the movement of the frame 4, the support plate 52 and the tray 53 of the bending assembly 6 position and support the H-shaped steel, and at the same time cooperate with the movement of the frame 4 to realize the bending operation. The frame 4 is provided with a jack 61 vertically connected thereto on the outside thereof, and the frame 4 is driven by the jack 61 to perform horizontal movement on the surface of the machine base 1, thereby horizontally pushing the H-shaped steel passing through. For the dynamic bending operation, the jack 61 uses an electric screw jack 61, which can not only improve the driving accuracy of the jack 61, but also simplify the driving method. The frame 4 is symmetrically provided with first slide rails 62 arranged on the surface of the base 1 and along the movement direction of the frame 4 on both sides in the width direction, and the first sliders 63 connected to the first slide rails 62 are symmetrically and spaced around the bottom of the frame 4. With the help of the cooperation of the first slider 63 and the first slide rail 62, the jack 61 is more stable when the traction frame 4 and the bending component 6 inside it move linearly.

[0049] When in use, according to the height size of the H-shaped steel, the support plate 52 and the tray 53 are rotated around the core rod 51 (at this moment, the core rod 51 needs to remain relatively still, and the power-off locking operation can be achieved with the help of the first motor 3 with a mechanical self-locking function, or the core rod 51 can be temporarily fixed manually using a clamp), and the spacing between the support plate 52 and the tray 53 is adjusted to ensure that they can fit tightly against the flange plate and the web plate of the H-shaped steel. According to the bending requirements, the position and height of the jack 61 are adjusted to ensure that the frame 4 can be accurately pushed to move horizontally, and the H-shaped steel to be processed is placed between the support plate 52 and the tray 53 of the traction assembly 5 to ensure accurate positioning, and the first motor 3 is started to drive the core rod 51 to rotate, drive the support plate 52 and the tray 53 to rotate, so as to pull the H-shaped steel to reciprocate to the bending position, and start the jack 61 to push the frame 4 to move horizontally. The bending assembly 6 in the frame 4 positions and supports the H-shaped steel, and cooperates with the movement of the frame 4 to achieve the bending operation. As needed, the above steps are repeated for multiple bending operations until the required bending angle and shape are achieved. Example

[0050] Based on the first embodiment, Figure 9-11As shown, a side support assembly 7 is arranged at the lower end of the interior of the stand 2, and the side support assembly 7 includes a support plate 71. There are two support plates 71, which are spaced and arranged in parallel along the vertical direction. One end of the support plate 71 is symmetrically provided with a roller 72 abutting against the other side of the web of the H-beam. The support plates 71 are connected by a plurality of vertically arranged support rods 73. With the help of the arrangement of the rollers 72, they can cooperate with the support plates 52 to clamp the web of the H-beam, thereby preventing the web of the H-beam from being separated from the support plate 52 during the bending process, thereby reducing the contact area between the H-beam and the traction assembly 5, and then causing traction slippage, thereby ensuring stable traction operation of the H-beam during the bending process.

[0051] The side support assembly 7 also includes a first screw rod 74, which is vertically arranged on one side of the support plate 71. A first screw sleeve 75 connected to the support rod 73 is threadedly connected to the upper portion of the first screw rod 74. A vertical plate 76 is vertically arranged on one side of the first screw rod 74. Both ends of the vertical plate 76 are symmetrically arranged with bearing seats for supporting the first screw rod 74. A second motor 77 connected to the first screw rod 74 through a coupling is arranged at one end of the vertical plate 76, so that the first screw rod 74 is driven to rotate by the second motor 77, so that the first screw sleeve 75 can convert the circumferential rotation of the first screw rod 74 into The roller 72 moves linearly in the vertical direction, so that the roller 72 can adjust its lateral support position according to the H-shaped steel of different heights to cooperate with the tray 53 to realize the lateral stable support operation of the H-shaped steel. The second slide rails 712 arranged along the movement direction of the first screw sleeve 75 are symmetrically arranged on both sides of the vertical plate 76, and the second sliders 713 connected to the second slide rails 712 are symmetrically and spaced on one side of the support rod 73. With the help of the cooperation between the second slider 713 and the second slide rail 712, the position adjustment movement of the roller 72 under the traction of the second motor 77 is more stable.

[0052] The side support assembly 7 also includes a transverse plate 78, which is placed horizontally below the vertical plate 76 and connected to the stand 2. A second screw 79 is arranged on the upper part of the transverse plate 78 along the midline position of its length direction. The upper part of the second screw 79 is threadedly connected to a second screw sleeve 710 connected to the vertical plate 76. Both ends of the second screw 79 are connected to the transverse plate 78 through bearing seats. A third motor 711 connected to the second screw 79 through a coupling is arranged at one end of the transverse plate 78, so that the second screw 79 is driven to rotate by the third motor 711, so that the second screw sleeve 710 can rotate the second screw 79 in the circumferential direction. The movement is converted into horizontal linear movement of the vertical plate 76, so that the roller 72 can adjust its lateral support position according to the H-shaped steel with different web thicknesses, so as to cooperate with the tray 53 to realize the lateral stable support operation of the H-shaped steel. The third slide rails 714 arranged along the movement direction of the second screw sleeve 710 are symmetrically arranged on both sides of the cross plate 78, and the third sliders 715 connected to the third slide rails 714 are symmetrically and spaced at the bottom of the vertical plate 76. With the help of the cooperation of the third slider 715 and the third slide rail 714, the position adjustment movement of the roller 72 under the traction of the third motor 711 is more stable.

[0053] When in use, according to the height size of the H-beam and the thickness of the web, firstly, the third motor 711 is used to drive the second screw 79 to rotate, and the horizontal position of the vertical plate 76 is adjusted so that the roller 72 initially approaches the web of the H-beam. Then, the second motor 77 is used to drive the first screw 74 to rotate, and the vertical position of the roller 72 is adjusted to ensure that the roller 72 moves to the center line position of the web of the H-beam. Then, the third motor 711 continues to drive the second screw 79 to rotate so that the roller 72 forms a firm contact with the web. Under the drive of the traction assembly 5, the H-beam moves along the platform 2 to the bending position. During this process, the roller 72 of the side support assembly 7 always maintains a close contact with the web of the H-beam to provide stable lateral support. When the jack 61 pushes the frame 4 to perform a bending operation, the roller 72 of the side support assembly 7 and the support plate 52 jointly clamp the web of the H-shaped steel to prevent it from detaching or slipping. According to different H-shaped steel sizes and bending requirements, the position of the roller 72 can be adjusted at any time by the second motor 77 and the third motor 711 to ensure that the side support assembly 7 always provides effective lateral support. The design of the side support assembly 7 enhances the stability of the H-shaped steel during the bending process and avoids detachment and slipping between the web and the support plate 52. Driven by the second motor 77 and the third motor 711, the side support assembly 7 can adjust its lateral support position according to H-shaped steels of different heights and web thicknesses, thereby improving the adaptability of the equipment. Example

[0054] On the basis of embodiment 1 or 2, Figure 12-16As shown, the surface of the core rod 51 has threads (internal threads), and keyways 54 are evenly and spacedly arranged in the circumferential direction of the core rod 51 along its axial direction. The tray 53 (no longer threadedly connected to the core rod 51) is divided into a base plate 55 at the lower end of the core rod 51 and a pressure plate 56 at the upper end of the core rod 51. The base plate 55 is connected to the core rod 51 through the keyway 54, so that the base plate 55 can slide directly to the bottom of the core rod 51 after installation, and the base plate 55 abuts against the bearing seat with an end cover at the bottom of the core rod 51. Therefore, the base plates 55 inside the traction assembly 5 and the bending assembly 6 can automatically maintain the same height to support the horizontal plane of the H-shaped steel, avoiding the need to adjust the rotation height of the base plates 55 one by one during the installation process to perform the plane correction operation between each other, so as to avoid the deformation operation of the H-shaped steel caused by longitudinal offset during the bending process due to the uneven height of the base plates 55. In addition, the base plate 55 adopts an integrated molding method to improve its load-bearing and anti-deformation capacity for the H-shaped steel, and the pressure plate 56 and the core rod 51 are also connected by a keyway 54. The pressure plate 56 is connected so that it can slide along the vertical direction of the core rod 51 after installation. The top of the platform 2 is evenly and spacedly arranged along its circumference with a pressing assembly 8 for applying vertical pressure to the pressure plate 56. The pressing assembly 8 includes a cylinder body 81, which is horizontally arranged on the inner side of the top of the platform 2. A cylinder rod 82 that slides back and forth is arranged inside the cylinder body 81 along its axial direction. The end of the cylinder body 81 has a support sleeve 83 that is sleeved with the cylinder rod 82. A ball head 84 is arranged at one end of the support sleeve 83. The end of the ball head 84 has a There is a ring 85 that rotates around the support sleeve 83, and the ring 85 is meshed with the cylinder rod 82, so that through the telescopic movement of the cylinder rod 82, the ring 85 drives the ball head 84 to flip vertically around the support sleeve 83, so that the ball head 84 abuts against the upper surface of the pressure plate 56, and then the pressure plate 56 can be firmly pressed on the upper surface of the upper flange plate of the H-beam. Compared with the threaded adjustment method of the first embodiment, the vertical downward pressing method can further cooperate with the base plate 55 to achieve the crimping traction effect of the H-beam.

[0055] When in use, first adjust the spacing between the support plates 52 and cooperate with the base plate 55 to perform a preliminary fixing operation on the H-beam. At this moment, the pressure plate 56 abuts against the upper surface of the upper flange plate of the H-beam under the action of its own gravity, and then the cylinder rod 82 extends along the cylinder body 81, and with the help of the meshing connection between its end and the ring 85, the ball head 84 at one end of the ring 85 is driven to flip vertically downward around the support sleeve 83, and then the ball head 84 abuts against the upper surface of the pressure plate 56, thereby increasing the downward pressure of the pressure plate 56 on the H-beam, so that the H-beam can achieve anti-warping traction operation in the height direction, avoiding the H-beam from warping and deformation in the height direction during traction and bending. Example

[0056] On the basis of Embodiment 1, 2 or 3, Fig.17 As shown, the support plate 52 is divided into a multi-stage coaxial sleeve arrangement of an outer plate 57, a middle plate 58 and an inner plate 59, and the outer plate 57, the middle plate 58 and the inner plate 59 are connected in sequence by bolts, so that through the loading and unloading of the outer plate 57, the middle plate 58 and the inner plate 59, it can adapt to the flange plates of H-shaped steels of different widths when placed between the support plate 52 and the tray 53, ensuring that the support plate 52 can form a stable contact with the web of the H-shaped steel.

[0057] When in use, first select a suitable combination of the support plates 52 according to the specific width of the H-beam, and adjust the width of the support plates 52 to match the width of the H-beam flange plate by disassembling or installing the outer plate 57, the middle plate 58 and the inner plate 59. Then, place the adjusted support plate 52 on the pallet 53, and place the flange plate of the H-beam between the support plate 52 and the pallet 53. Finally, ensure that the support plate 52 forms a stable contact with the web of the H-beam for subsequent processing operations. The support plate 52 structure with a multi-stage coaxial sleeve arrangement can flexibly adapt to H-beams of different widths, thereby improving the versatility and practicality of the equipment. The outer plate 57, the middle plate 58 and the inner plate 59 connected by bolts are stable and reliable, ensuring the stable contact between the support plate 52 and the web of the H-beam, thereby improving the safety and accuracy during processing.
