Description

Technical Field

[0001] This invention relates to the field of steel truss production equipment technology, specifically to an automatic adjustment device for steel truss curved wave forming. Background Technology

[0002] With the rapid development of the construction industry, steel trusses are widely used in large-scale engineering construction fields such as bridges, tunnels, railways, highways, and prefabricated concrete component factories due to their economic, convenient, safe, and reliable characteristics. The function of the truss production line's bending forming device is to process truss web reinforcement of different heights and pitches by bending the steel bars. Currently, there are various types of truss bending forming devices, including chain extrusion forming, swing bending forming, and hydraulic jacking bending forming. Among them, the chain extrusion forming device cannot achieve free height switching, resulting in a significant waste of a long section of steel reinforcement after the truss web reinforcement changes height. Furthermore, the formed web reinforcement needs to be transported over a long distance to the welding station, making it difficult to ensure the original waveform and dimensional consistency of the web reinforcement during transport. The swing bending forming device can achieve free height switching, but the formed web reinforcement still needs to be transported over a long distance to the welding station, resulting in lower forming accuracy. The hydraulic jacking bending forming device can solve the problems of height switching and forming accuracy, but the forming of trusses of different heights is achieved by lifting them to the mechanical limit position with a hydraulic cylinder, resulting in significant noise and impact on the equipment. This invention provides an automatic adjustment device for the curved forming of steel trusses to solve the above-mentioned problems. Summary of the Invention

[0003] This invention provides an automatic adjustment device for the curved wave forming of steel trusses, which enables free switching of bending height and pitch, reduces mechanical impact, improves the forming accuracy and stability of trusses, and ensures the consistency of the waveform of the finished trusses.

[0009] Furthermore, the top wave structure includes a top wave base, a power unit three, and a lifting structure.

[0010] Furthermore, the power mechanism includes a power unit four, a horizontal adjustment structure, a limiting structure, a mounting shaft, a connecting crank, and a power base.

The mounting shaft and the power unit four are mounted on the power base. The power base is connected to the mounting shaft and drives the mounting shaft to rotate.

Detailed Implementation

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing this patent and simplifying the description, 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. Therefore, they should not be construed as limitations on this patent.

[0034] like Figure 1 , 2As shown in Figure 3, an automatic adjustment device for forming curved sections of a steel truss includes a frame 1, a power mechanism 2, a swinging link 3, a swinging mechanism 4, a curved section forming mechanism 5, and a positioning mechanism 6. The frame 1 serves as the mounting base for the power mechanism 2, the swinging link 3, the swinging mechanism 4, the curved section forming mechanism 5, and the positioning mechanism 6. The power mechanism 2, the swinging link 3, and the swinging mechanism 4 are located on one side of the frame 1, forming an adjustable swinging structure that drives the curved section forming mechanism 5. The swinging frequency and amplitude are controlled by adjusting the power mechanism 2 and the swinging mechanism 4. The swinging mechanism 4 is connected to the power mechanism 2 through the swinging link 3. The curved section forming mechanism 5 and the positioning mechanism 6 are located on the frame 1. The curved section forming mechanism 5 is located on the other side of the frame 1, and the positioning mechanism 6 is located on the rear side of the frame 1 and behind the curved section forming mechanism 5. The curved section forming mechanism 5 is connected to the swinging mechanism 4 and works with the positioning mechanism 6 to bend the web reinforcement of the steel truss. The power mechanism 2, the swinging mechanism 4, the curved section forming mechanism 5, and the positioning mechanism 6 are linked together.

[0035] The driving principle of the overall structure of this invention embodiment is as follows: The power mechanism 2 is movably mounted on the frame 1. By adjusting its own position and the position of the sliding structure 44 on the swing mechanism 4, the sliding structure 44 is connected to the power mechanism 2 via the swing linkage 3. The above adjustments can change the swing radius and swing angle of the swing mechanism 4, thereby realizing the feeding distance of the wave-forming mechanism 5. The positioning mechanism 6 presses the steel truss, thereby forming waveforms of different shapes on the web reinforcement of the steel truss. This invention adjusts the amplitude of the wave-forming mechanism 5 by adjusting the power mechanism 2 and the swing mechanism 4, forming different waves on the steel reinforcement. At the same time, by adjusting the position of the positioning foot 62 on the positioning mechanism 6, it adapts to steel trusses with different node spacings.

[0036] The operating principle of this embodiment is as follows: The power mechanism 2, the swing linkage 3, and the swing mechanism 4 form an adjustable swing structure. The mounting shaft 24 on the power mechanism 2 serves as the rotation center for power output. The connecting crank 25 is fixedly connected to the mounting shaft 24, and its rotation radius is equal to the length of the crank. The distance between the slider on the sliding structure 44 and the mounting shaft 24 is equal to the length of the rocker arm. The two ends of the swing linkage 3 are movably connected to the slider and the connecting crank 25, respectively. When the power device 41 drives the mounting shaft 24, the connecting crank 25 rotates, and the swing linkage 3 drives the swing mechanism 4 to swing within a certain range. When the swing mechanism 4 rotates, it drives the main shaft 42 to move with a corresponding amplitude. The wave-forming mechanism 5 connected to the main shaft 42 also moves along with the main shaft 42. The lever arm 51 of the wave forming mechanism 5 moves with the main shaft 42 at a corresponding amplitude. The long connecting rod 52 and the short connecting rod 53 connected to the lever arm 51 move together with the lever arm 51, thereby driving the wave pushing structure 54 and the top wave structure 55 to reciprocate within a certain range. When the wave pushing structure 54 moves to the farthest distance from the positioning mechanism 6, the pressing structure 543 presses the steel bar. Then the top wave structure 55 and the wave pushing structure 54 move forward at an adjustable speed ratio. At the same time, the lifting structure 553 moves upward, and its speed matches the speed of the wave pushing structure 54. When the wave pushing structure 54 reaches the end point, the lifting structure 553 reaches the highest point at the same time, bending the steel bar. After that, the wave pushing structure 54 and the top wave structure 55 are reset, waiting for the next wave forming.

[0037] like Figure 6 , 7 As shown, the swing mechanism 4 further includes a swing housing 41, a main shaft 42, a power device 43, a sliding structure 44, and a locking structure 45. The main shaft 42 serves as the power input structure for the wave-forming mechanism 5. The swing housing 41 is connected to the main shaft 42. When the swing housing 41 moves, it drives the main shaft 42 to move together, transmitting the swing amplitude to the wave-forming mechanism 5 through the main shaft 42. The main shaft 42 passes through the frame 1, with one end connected to the swing housing 41 and the other end connected to the wave-forming mechanism 5. The main shaft 42 serves as the rotation center of the swing mechanism 4. The slider on the sliding structure 44 serves as the power fulcrum of the swing mechanism 4. The sliding structure 44 is located in the swing housing 41 and connected to the swing connecting rod 3. The sliding structure 44 serves as the power point for the swing of the swing mechanism 4. The locking structure 45 is located on the sliding structure 44. The power device 43 is located on the swing housing 41 and connected to the sliding structure 44.

[0038] The swing amplitude adjustment principle of the swing mechanism 4 in this embodiment is as follows: The main shaft 42 is located at the lower part of the swing box 41, serving as the rotation center of the swing box 41. The sliding structure 44 is located in the swing box 41. The slider moves on the slide rod, changing the distance between the slider and the main shaft 42, thereby adjusting the rotation radius of the swing box 41 and thus adjusting the swing amplitude of the swing box 41. After changing the swing amplitude of the swing box 41, the change is transmitted to the wave forming mechanism 5 through the main shaft 42, thereby realizing the change of wave forming height and pitch respectively.

[0039] In this embodiment, the power unit 43 in the swing mechanism 4 is used to drive the sliding structure 44 to change the distance of the slider on the slide rod. The locking structure 45 is used to lock the slider. After the slider moves into place, the slider is locked by the locking structure 45.

[0040] like Figure 6 As shown, the sliding structure 44 further includes a slide rod and a slider. The slide rod is disposed in the swing box 41 and is arranged along its length. The slider is movably connected to the slide rod. The power device 43 is connected to the slide rod and drives the slide rod to move, thereby causing the slider to move on the slide rod, so that the sliding structure 44 swings at different amplitudes.

[0041] Preferably, the sliding structure 44 is a lead screw and nut structure, the slide rod is a lead screw, and the slider is a nut slider, which is threadedly connected to the lead screw. The end of the slide rod is movably connected to the swing box 41 and connected to the power device 43. The power device 43 drives the slide rod to rotate, thereby driving the slider to move on the slide rod.

[0042] Preferably, the locking structure 45 is a friction chuck device driven by a cylinder. After the slider is in place, the cylinder drives the chuck to lock it, thereby restricting and locking the slider position.

[0043] like Figure 8 , 9 As shown, the curved wave forming mechanism 5 further includes a lever arm 51, a long connecting rod 52, a short connecting rod 53, a wave-pushing structure 54, and a top wave structure 55. The wave-pushing structure 54 and the top wave structure 55 are mounted on the frame 1 via guide rails. The wave-pushing structure 54 is located in front of the top wave structure 55. The outer ends of the long connecting rod 52 and the short connecting rod 53 are movably connected to the wave-pushing structure 54 and the top wave structure 55, respectively. The outer end of the lever arm 51 is movably connected to one end of the main shaft 42. The inner ends of the long connecting rod 52 and the short connecting rod 53 are hinged to the lever arm 51. The long connecting rod 52 is hinged to the inner end of the lever arm 51, and the short connecting rod 53 is hinged to the middle of the lever arm 51.

[0044] The principle of the curved wave forming mechanism 5 for forming curved steel bars is as follows: The lever arm 51 is movably connected to the pushing wave structure 54 and the top wave structure 55 through the long connecting rod 52 and the short connecting rod 53 respectively, so that the pushing wave structure 54 and the top wave structure 55 move along the guide rail at a fixed speed ratio. While the pushing wave structure 54 and the top wave structure 55 move horizontally along the guide rail together, the pushing wave structure 54 presses the steel bar and pushes the steel bar to move backward together. While the top wave structure 55 moves horizontally, it lifts upward at the same time, bending the steel bar upward. The pushing wave structure 54 and the top wave structure 55 cooperate with each other to bend the web reinforcement of the steel truss into an isosceles triangle.

[0045] like Figure 10 As shown, the wave-pushing structure 54 further includes a wave-pushing base 541, a second power device 542, and a pressing structure 543. The wave-pushing base 541 is mounted on the frame 1 via a guide rail and is movably connected to the long connecting rod 52. The pressing structure 543 is mounted on the wave-pushing base 541, and the second power device 542 is mounted on the pressing structure 543 to drive the pressing structure 543 to move. The pressing structure 543 includes a pressing shaft and a pressing seat, and the pressing shaft is connected to the second power device 542.

[0046] Furthermore, the clamping seat is fixedly connected to the push wave base 541, and the clamping shaft is connected to the power device 542 through a cam structure, which periodically drives the clamping shaft to move up and down. When the clamping shaft moves down, it cooperates with the clamping seat to clamp the steel bar. When the clamping shaft moves up, it releases the steel bar, and the steel bar can be fed at this time, waiting for the next bending action. The clamping shaft and the clamping seat cooperate with each other.

[0047] The working principle of the wave-pushing structure 54 is as follows: the wave-pushing base 541 moves horizontally on the frame 1 along the guide rail driven by the long connecting rod 52. Before moving, the pressing structure 543 is driven down by the power device 542 to press the steel bar, and together with the positioning mechanism 6, it fixes the steel bar. Then, when the wave-pushing base 541 moves horizontally, it presses the front end of the steel bar backward, while the wave-pushing structure 55 pushes it upward to bend the steel bar.

[0048] like Figure 11 As shown, the top wave structure 55 further includes a top wave base 551, a power unit 552, and a lifting structure 553. The top wave base 551 is mounted on the frame 1 via a guide rail and is movably connected to the short connecting rod 53. The lifting structure 553 is located in the top wave base 551 and is connected to the power unit 552.

[0049] The working principle of the top wave structure 55 is as follows: The top wave base 551 is set on the frame 1 through the guide rail. Driven by the short connecting rod 53, it moves horizontally on the frame 1 along the guide rail. During the movement, the lifting structure 553 is pushed by the power device 552 to lift and lower on the top wave base 551. Its top lifts the steel bar, so that the steel bar is bent and formed.

[0050] The push wave structure 54 and the top wave structure 55 work together under the drive of the lever arm 51, and at the same time, under the drive of the second power device 542 and the third power device 552 respectively, they respectively realize the tightening and loosening of the steel bars and the lifting and bending action, so as to realize the continuous bending operation of the steel bars.

[0051] like Figure 4 , 5 As shown, the power mechanism 2 further includes a power unit 21, a horizontal adjustment structure 22, a limiting structure 23, a mounting shaft 24, a connecting crank 25, and a power base 26. The power base 26 is mounted on the frame 1 via a guide rail, serving as the mounting base for the power unit 21, the horizontal adjustment structure 22, the limiting structure 23, the mounting shaft 24, and the connecting crank 25. The horizontal adjustment structure 22 and the limiting structure 23 are respectively located on both sides of the power base 26. The horizontal adjustment structure 22 drives the power base 26 to move along the guide rail on the frame 1. The limiting structure 23 is connected to the frame 1 and is used to limit the position of the power base 26. The mounting shaft 24 and the power unit 21 are mounted on the power base 26. The power base 26 is connected to the mounting shaft 24 and drives the mounting shaft 24 to rotate. The connecting crank 25 is connected to the mounting shaft 24 and is connected to the swing linkage 3.

[0052] The power unit 21 is mounted on the power base 26 and outputs power to the mounting shaft 24. The connecting crank 25 is mounted on the mounting shaft 24 and moves together with the mounting shaft 24. When the connecting crank 25 rotates, it drives the swing connecting rod 3 to move and rotate, thereby driving the swing mechanism 4 to swing.

[0053] Preferably, the connecting crank 25 is mounted on the mounting shaft 24 either upright or inverted as needed, so that the rotation radius of the connecting crank 25 relative to the mounting shaft 24 changes, thereby satisfying the processing of steel trusses with different height ranges.

[0054] The horizontal adjustment structure 22 and the limiting structure 23 are respectively located on both sides of the power base 26. The horizontal adjustment structure 22 drives the power base 26 to move horizontally through its own movement. After the movement is in place, the limiting structure 23 locks the position of the power base 26 to prevent the power base 26 from shifting during operation.

[0055] Preferably, the power unit 21 includes an electric motor and a reducer, the reducer is mounted on the power base 26, and the power base 26 is connected to the frame 1 via a guide rail.

[0056] Preferably, the horizontal adjustment structure 22 is a lead screw driven by a motor, and the power base 26 is connected to the lead screw by a thread. When the horizontal adjustment structure 22 is activated, the power base 26 moves horizontally on the lead screw.

[0057] Preferably, the limiting structure 23 is an automatically controlled ratchet rack and pinion stop. The automatically controlled ratchet structure is mounted on the power base 26 and moves with the power base 26. Its automatic action is linked to the horizontal adjustment structure 22, and the stop rack is mounted on the frame 1. After the power base 26 is in position, the ratchet structure on the limiting structure 23 is controlled to move under the drive of a cylinder, engaging with the stop rack on the frame 1 to fix the position of the power base 26, thus limiting the position of the power base 26.

[0058] like Figure 12 , 13 As shown, the positioning mechanism 6 is located behind the curved wave forming mechanism 5, and is arranged correspondingly to the front and rear. It includes a positioning base 61, positioning pressure feet 62, and a position adjustment structure 63. The positioning base 61 is fixedly connected to the frame 1. The positioning pressure feet 62 are spaced apart on the positioning base 61 and include fixed pressure feet and movable pressure feet. The position adjustment structure 63 is located on the positioning base 61 and is connected to the movable pressure feet, driving the movable pressure feet to move and adjust the spacing of the positioning pressure feet 62, thereby adapting to steel trusses with different node spacings.

[0059] Furthermore, the positioning foot 62 is movably connected to the positioning base 61, and both the fixed foot and the movable foot are equipped with a power device.

[0060] Furthermore, the main shaft 42 is fixedly connected to the end of the swing box 41, and the sliding structure 44 is movably disposed in the swing box 41 and moves along the swing box 41.

[0061] Preferably, the power device 1 43, power device 2 542, power device 3 552 and power device 4 21 are electric motors, and the power device 5 is a cylinder.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.
