Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal pipe processing, in particular to a metal pipe processing device for highway construction. BACKGROUND

[0002] In the field of highway construction, metal pipes are widely used, such as in the drainage system of highway bridges, cable protection sleeves in tunnels, and support structures of highway guardrails. In order to adapt to different construction scenes and installation requirements, these metal pipes often need to be processed according to actual needs, such as bending and cutting. Therefore, metal pipe processing devices play a crucial role in highway construction.

[0003] Currently, many metal pipe processing devices used in highway construction sites mainly rely on manual operation in the feeding and discharging process. Workers need to carry the metal pipes from the storage place to the workbench of the processing device, and then carry the finished pipes to the designated place for stacking after processing. Since the metal pipes required for highway construction usually have a large length and weight, such as some large metal pipes used for bridge drainage, with a single weight of tens of kilograms or even hundreds of kilograms, manual carrying not only consumes a lot of physical strength, but also slows down the carrying speed, seriously affecting the processing efficiency.

[0004] Some existing metal pipe processing devices have certain processing functions, but lack effective automated auxiliary mechanisms in feeding and discharging. For example, the workbench height of some devices is fixed, and no lifting or tilting mechanism is provided. Workers need to adjust the carrying posture according to the height of the workbench when placing the metal pipe on the workbench, increasing the difficulty and complexity of the operation.

[0005] In highway construction, the bending angle requirements of metal pipes are diverse. For example, in the support structure of highway guardrails, metal pipes may need to be bent at different angles according to the terrain and design requirements to achieve stable support effect. However, many existing metal pipe processing devices have a narrow bending angle adjustment range, usually only a few fixed angles can be achieved, which cannot meet the needs of multi-angle bending of metal pipes in highway construction.

[0006] Most existing metal pipe processing devices can only achieve single-angle bending. For metal pipes that need to be bent at multiple angles at the same time, multiple processing is required, and the position and angle of the metal pipe need to be adjusted after each processing, which not only increases the processing time and labor intensity, but also easily causes damage to the metal pipe during multiple processing, reducing the quality and service life of the metal pipe. SUMMARY

[0018] Preferably, the right rear end of the support is provided with a power distribution operation cabinet.

[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1. The present application realizes precise control of the metal pipe processing process by controlling the coordinated operation of the adjusting rod, the sliding table and the electromagnet. In the initial positioning and center position adjustment stage, the metal pipe can be accurately moved to the specified position, and the bending area is ensured to be in the center, so that the two side clamping pipes are the same distance from the bending area. This precise operation ensures that the metal pipe is evenly stressed on both sides during bending, effectively avoiding the problem of poor bending effect caused by uneven stress, greatly improving the quality and precision of metal pipe bending, and meeting the scenes with high precision requirements for metal pipe processing.

[0021] 2. When bending a metal pipe of a specific shape, the cooperation of the adjusting rod and the sliding table realizes a unique bending mode. During the bending process, the sliding table moves from the outside to the inside, and the adjusting rod gradually rotates upward, so that the clamping pipe position moves from the outside to the inside, not only increasing the bending effect and rate, realizing secondary acceleration, but also forming a labor-saving lever in the early stage of bending, reducing equipment wear and tear, and facilitating stable bending. At the same time, by controlling the electric push rod, the angle of the clamping pipe can be changed, and metal pipes of various shapes such as two-side inclination can be processed, meeting the diversified needs of different customers for the shape of metal pipes, and enhancing the versatility and flexibility of the equipment.

[0022] 3. The design is very convenient in the feeding and discharging links. For the metal pipe in the horizontal state on both sides, the feeding and discharging can be automatically completed by controlling the adjusting rod and the sliding table, without manual operation, saving manpower and time. When feeding, the electric push rod is controlled to shrink a small distance to make the clamping pipe inclined, and the metal pipe can slide along the clamping pipe relying on gravity, reducing energy consumption and processing cost. This convenient and labor-saving feeding and discharging mode improves the overall processing efficiency and makes the equipment more advantageous in production application.

[0036] The specific embodiments of the present application are described in detail below. Figures 1-12 The specific embodiments of the present application are described in detail below.

[0037] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0038] In the prior art, metal pipe processing devices generally have technical bottlenecks of relying on manual operation for feeding and discharging and limited adjustment range of bending angle. The workbench of the traditional device is fixed in height and lacks a lifting mechanism, and the operator needs to repeatedly adjust the carrying posture to adapt to different processing requirements. For the common multi-angle bending requirement in highway construction, the existing equipment often needs to be positioned and processed repeatedly for multiple times, resulting in low processing efficiency and the risk of pipe damage.

[0039] To solve the above problems, the researchers observed that there are three core contradictions in the metal pipe processing process: the contradiction between the efficiency of manual carrying of heavy pipes and the construction progress, the contradiction between the single-angle bending mechanism and the complex construction requirement, and the contradiction between the fixed workbench and the diversified processing scene. By analyzing the bending stress principle of the metal pipe, it is found that the dynamic matching of the bending fulcrum position and the clamping height is the key breakthrough to realize multi-angle processing. Based on this, a solution combining an adjustable support structure and a power clutch device is proposed, and the processing parameters are quickly switched through modular design.

[0040] The present application provides a metal pipe processing device for highway construction, comprising a support 101, a slide rail 102 is arranged on the top of the support 101, the slide rail 102 is a guide structure extending longitudinally along the support 101, and can be implemented by a linear guide rail or a T-shaped groove track, used for bearing a sliding table 106 and limiting the movement track of the sliding table 106, two sliding tables 106 are arranged symmetrically on the top of the slide rail 102, the two sliding tables 106 are symmetrically arranged with the center line of the slide rail 102 as the axis of symmetry, the sliding table 106 is a bearing platform moving along the slide rail 102, and can be implemented by a moving base with a roller, the symmetric arrangement design can adapt to metal pipes of different lengths, an adjusting assembly is arranged on the top of the sliding table 106, a support rod 204 is arranged on the top of the adjusting assembly, the adjusting assembly can change the front and back positions of the support rod 204, a bending column 203 is arranged at the top of the middle part of the support 101, the bending column 203 serves as a bending fulcrum, and the stepped structure thereof can match pipes of different diameters, when the metal pipe needs to be processed, the two sliding tables 106 are symmetrically moved to the predetermined positions along the slide rail 102, forming a clamping interval matching the length of the pipe. The adjusting assembly drives the support rod 204 to move to the front end, so that the metal pipe is fed and discharged, and interference with the bending column 203 is avoided. Figures 1-12

[0041] The present application comprises a support 101, a slide rail 102 is arranged on the top of the support 101, the slide rail 102 is a guide structure extending longitudinally along the support 101, and can be implemented by a linear guide rail or a T-shaped groove track, used for bearing a sliding table 106 and limiting the movement track of the sliding table 106, two sliding tables 106 are arranged symmetrically on the top of the slide rail 102, the two sliding tables 106 are symmetrically arranged with the center line of the slide rail 102 as the axis of symmetry, the sliding table 106 is a bearing platform moving along the slide rail 102, and can be implemented by a moving base with a roller, the symmetric arrangement design can adapt to metal pipes of different lengths, an adjusting assembly is arranged on the top of the sliding table 106, a support rod 204 is arranged on the top of the adjusting assembly, the adjusting assembly can change the front and back positions of the support rod 204, a bending column 203 is arranged at the top of the middle part of the support 101, the bending column 203 serves as a bending fulcrum, and the stepped structure thereof can match pipes of different diameters, when the metal pipe needs to be processed, the two sliding tables 106 are symmetrically moved to the predetermined positions along the slide rail 102, forming a clamping interval matching the length of the pipe. The adjusting assembly drives the support rod 204 to move to the front end, so that the metal pipe is fed and discharged, and interference with the bending column 203 is avoided.​

[0042] The support rod 204 has a control component inside, and an adjusting rod 304 is located on the front side of the control component. The control component can precisely control the rotation angle of the adjusting rod 304, thereby changing the position and height of the outer hinge point of the adjusting rod 304 (e.g., Figure 12 As shown, the top of the adjusting rod 304 is provided with a clamping tube 305. The internal diameter of the clamping tube 305 is the same as that of the metal tube to be processed, which facilitates the passage of the clamping tube 305. By moving the clamping tube 305 and adjusting its height, the loading, unloading and bending operations of the metal tube can be completed. The rear side of the clamping tube 305 is provided with a transmission rod 410. The clamping tube 305 can rotate with the rotation of the transmission rod 410. The rear side of the transmission rod 410 is provided with a clutch assembly. The clutch assembly can control the rotation of the transmission rod 410, which can realize the clamping tube 305 moving horizontally at all times, or the clamping tube 305 rotating freely and moving at a fixed angle, to complete different operations. The front end of the transmission rod 410 is provided with a reset assembly. The reset assembly automatically returns to the initial state after completing a single bend, preparing for the next processing.

[0043] The clutch assembly includes an electric push rod 403, which can extend and retract according to specific conditions after being energized. The outer wall of the electric push rod 403 is provided with a toothed block 404, and the top of the toothed block 404 is fitted with a toothed groove 405. When the toothed block 404 and the toothed groove 405 are interlocked, the electric push rod 403 can be constrained from rotating. The top of the toothed groove 405 is provided with a limiting block 406, and the inner side of the limiting block 406 is connected to the adjusting rod 304. When the electric push rod 403 retracts, since the top height of the electric push rod 403 remains unchanged, it will drive the non-extending part of the electric push rod 403 to move upward, thereby driving the toothed block 404 and the toothed groove 405 to engage with each other, thus constraining the rotation of the electric push rod 403.

[0044] Each slide table 106 has a threaded rod 105 on its outer side, and a first motor 104 is mounted on the outer side of each threaded rod 105. The bottom of the first motor 104 is connected to the bracket 101. The inner side of the threaded rod 105 is rotatably connected to the slide rail 102. After the first motor 104 starts, it drives the threaded rod 105 to rotate around its own axis. The threaded rod 105 and the threaded hole on the outer side of the slide table 106 form a helical transmission pair. Under the rotation of the threaded rod 105, the slide table 106 generates horizontal displacement along the slide rail 102. Because the rotatable connection between the inner side of the threaded rod 105 and the slide rail 102 restricts the axial movement of the threaded rod 105, the rotation of the threaded rod 105 is converted only into the linear motion of the slide table 106. By controlling the direction and speed of the first motors 104 on both sides respectively, the two slide tables 106 can adjust their spacing synchronously or asynchronously to adapt to the processing requirements of metal tubes of different lengths.

[0045] Compared with the prior art, the traditional slide table 106 adjustment needs manual rotation of the screw rod or pulling of the mechanical handle, and has the problems of slow adjustment speed and low positioning accuracy. The scheme realizes automatic adjustment of the slide table 106 by driving the threaded rod 105 by the motor, eliminates the human operation link, and uses the self-locking characteristic of the threaded transmission to ensure that the slide table 106 remains stable in position during processing.

[0046] The adjustment assembly includes a support plate 201, the bottom of the support plate 201 is connected with the top of the slide table 106, the support plate 201 is a rigid platform for bearing the hydraulic rod 202, and can be implemented by a welded steel plate structure, and the bottom of the support plate 201 forms a sliding fit relationship with the slide table 106, and is used to maintain the overall stability of the adjustment assembly during lateral movement. The hydraulic rod 202 is arranged at the top rear end of the support plate 201, and the front end top of the hydraulic rod 202 is connected with the support rod 204. When it is necessary to adjust the front and rear positions of the support rod 204, the position adjustment can be realized by the extension and contraction of the hydraulic rod 202, so that the metal pipe is convenient for feeding and discharging, and is convenient for multi-angle bending.

[0047] The control assembly includes a second motor 301, the inner side of the second motor 301 is connected with the support rod 204, the top of the second motor 301 is provided with a worm 302, the side of the worm 302 is provided with a worm gear 303, the outer side of the worm gear 303 is connected with an adjustment rod 304, and the second motor 301 drives the worm 302 to rotate around the axis thereof after being started. The helical teeth of the worm 302 are engaged with the external teeth of the worm gear 303, and the rotating motion is transmitted to the worm gear 303. The worm gear 303 is fixedly connected with the adjustment rod 304, so that the adjustment rod 304 rotates synchronously with the worm gear 303, and in turn drives the clamping pipe 305 to adjust the angle around the axis of the adjustment rod 304. The worm gear 303 worm 302 transmission mechanism has a self-locking characteristic. When the second motor 301 stops running, the frictional resistance of the meshing surface of the worm 302 and the worm gear 303 prevents the adjustment rod 304 from rotating in the reverse direction due to external load, so as to keep the angle position of the clamping pipe 305 stable. By controlling the rotation direction and the number of rotations of the second motor 301, the rotation angle of the worm gear 303 can be accurately adjusted, and in turn the continuous adjustment of the bending angle of the metal pipe can be realized.

[0048] The application realizes stepless continuous adjustment of the bending angle of the metal pipe, and no manual intervention is needed in the operation process. The self-locking characteristic of the worm gear 303 worm 302 transmission mechanism can prevent the position of the adjustment rod 304 from deviating during processing, and ensure the consistency of the bending angle processing. By replacing the traditional manual adjustment with the motor driving mode, the processing needs of the multi-angle composite bending of the metal pipe in the highway construction can be met, the number of repeated positioning is reduced, and the processing efficiency is improved.

[0049] The inner rear side of the clamping pipe 305 is provided with an electromagnet 412, which is a magnetic device that generates a magnetic field by electric current, and can be implemented by a coil structure with a core. When energized, it generates an attractive force perpendicular to the axial direction of the metal pipe. The inner rear side of the clamping pipe 305 refers to the inner wall area of the pipe body in the direction close to the transmission rod 410, which can be implemented by a ring groove mounting method, so that the magnetic field generated by the electromagnet 412 covers the contact surface of the rear end of the metal pipe.

[0050] Specifically, when the metal pipe is placed inside the clamping pipe 305, the electromagnet 412 forms a closed magnetic field loop in the energized state, and tightly attracts the rear end of the metal pipe to the inner wall of the clamping pipe 305 by magnetic force. The direction of the attractive force forms an angle with the bending force direction of the metal pipe during processing, for example, it can be set to be approximately perpendicular, so that a two-way constraint is formed during processing. After processing is completed, the current is cut off, and the magnetic field disappears immediately. The metal pipe and the clamping pipe 305 only need to overcome the residual magnetic force to separate.

[0051] The top of the electric push rod 403 is provided with a cylindrical rod 407, which is rotationally connected with the limiting block 406. When the cylindrical rod 407 rotates, it can drive the electric push rod 403 to rotate synchronously. The top of the cylindrical rod 407 is provided with a third bevel gear 408, the front end of which is engaged with a fourth bevel gear 409, the front end of which is fixedly connected with the transmission rod 410. The third bevel gear 408 at the top of the cylindrical rod 407 transmits the rotary motion to the fourth bevel gear 409 engaged therewith, and the fourth bevel gear 409 converts the rotary direction to a direction parallel to the axis of the transmission rod 410, and transmits power to the transmission rod 410 through fixed connection. The bottom of the electric push rod 403 is fixedly connected with a second bevel gear 402, the bottom front side of which is engaged with a first bevel gear 401, the front end of which is fixedly connected with the rear side of the supporting rod 204. When the adjusting rod 304 rotates, it can drive the second bevel gear 402 to rotate around the first bevel gear 401, and can realize the revolution of the second bevel gear 402 while rotating under the action of the first bevel gear 401. When the adjusting rod 304 rotates clockwise under the viewing angle shown in the figure, the second bevel gear 402 will rotate counterclockwise at this time, and the third bevel gear 408 will rotate counterclockwise through the electric push rod 403 and the cylindrical rod 407, and the fourth bevel gear 409 will rotate counterclockwise driven by the third bevel gear 408, that is, when the adjusting rod 304 rotates clockwise, the clamping pipe 305 will rotate counterclockwise by the same angle, so that the clamping pipe 305 can always maintain a horizontal state during rotation with the adjusting rod 304. Figure 9

[0052] ​The reset assembly comprises a coil spring 411, one end of the coil spring 411 is fixedly connected with the transmission rod 410, and the other end of the coil spring 411 is fixedly connected with the rear side wall of the adjusting rod 304. The coil spring 411 is made of spring steel material, the inner end is fixed with the transmission rod 410 by welding or buckling, and the outer end is fixed with the rear side wall of the adjusting rod 304 by bolting or riveting. When the transmission rod 410 is subjected to external force, the coil spring 411 is elastically deformed and stores energy, and after the external force disappears, the transmission rod 410 is driven to reset by the elastic restoring force.

[0053] The right rear end of the support 101 is provided with a power distribution operation cabinet 103, which is fixed on the main frame of the support 101 by welding or bolting, and the position is convenient for the right hand of the operator to reach when standing and away from the metal pipe processing area. The power distribution operation cabinet 103 refers to a closed box structure integrating electrical control elements, which can be realized by an industrial control cabinet with a touch screen, button switch and circuit breaker, and the internal circuit is electrically connected with the slide table 106 drive motor, hydraulic rod 202 electromagnetic valve and clutch assembly.

[0054] Specifically, the operator can simultaneously adjust the synchronous movement distance of the slide table 106 along the slide rail 102, the lifting height of the hydraulic rod 202 and the meshing state of the clutch assembly through the centralized control interface of the power distribution operation cabinet 103 during processing. When it is necessary to adjust the metal pipe clamping position, the operator can complete the movement speed setting of the slide table 106 on the power distribution operation cabinet 103 without leaving the work station, and simultaneously adjusts the lifting action of the adjusting assembly through the preset program linkage control. The right side layout of the power distribution operation cabinet 103 enables the operator to naturally stretch the right arm to complete parameter setting when facing the processing area, and the rear mounting position forms physical isolation between the operator and the bending column 203, effectively blocking the metal scraps generated during processing into the control elements.

[0055] Specifically, in the initial stage of processing, the two adjusting rods 304 are controlled to rotate downward at the same time, and rotate to the downward state, at which time the two clamping pipes 305 are at the lowest position, and then the two slide tables 106 are controlled to move to the left side at the same time. During the movement, the left clamping pipe 305 will first contact the metal pipe, and then the metal pipe penetrates the left clamping pipe 305, and the electromagnet 412 in the clamping pipe 305 generates magnetic force by being electrified to adsorb and fix the metal pipe. Then the left clamping pipe 305 moves to the right to drive the metal pipe to move to the right, and then penetrates the right clamping pipe 305, and then the left electromagnet 412 is de-energized and the right electromagnet 412 is energized. At the same time, the right slide table 106 moves to the right, and the left clamping pipe 305 becomes a guide to move the metal pipe to the designated position.

[0056] If the center position of the metal pipe needs to be adjusted, the electromagnets 412 on both sides are controlled to be powered on at the same time, and then the two sliding tables 106 are controlled to move to the left or right at the same time, so that the whole metal pipe moves left or right, thereby adjusting the bending area. After the bending area is aligned with the bending column 203, the electromagnets 412 on the left and right sides are controlled to be powered on and off in sequence, and the sliding table 106 is controlled to move, so that the bending area is in the center, and the distance between the two clamping pipes 305 and the bending area is the same, ensuring that the forces on both sides are the same during bending, and ensuring the bending effect.

[0057] If the metal pipe needs to be bent to the state shown in Figure 5 , the two adjusting rods 304 are controlled to rotate upwards at the same time. During the rotation, the distance between the two clamping pipes 305 increases, and the electromagnets 412 inside the clamping pipes 305 are not powered on. Under the action of the bending column 203, the middle part of the metal pipe begins to sag towards the bottom, and then the two metal pipes continue to remain horizontal under the constraint of the clamping pipes 305, finally reaching the state shown in Figure 5 . During this process, the two sliding tables 106 gradually move from the outside to the inside. When the sliding table 106 is on the outside, the two clamping pipes 305 are also on the outside. At this time, it means that the force point of the metal pipe during bending is on the outside, which is a force-saving lever that can effectively reduce the wear and tear of other instruments, making it easier to bend stably in the early stage of bending. As the bending progresses, the two sliding tables 106 gradually move inward, which can increase the bending angle and speed. During this process, the two adjusting rods 304 also gradually rotate upwards, and the position of the clamping pipe 305 also moves from the outermost to the inside, further increasing the bending effect and speed, achieving secondary acceleration of the pipe bending.

[0058] At the end of the pipe bending, the two clamping pipes 305 also move to the highest position. If the angle of the bent pipe needs to be increased at this time, the two sliding tables 106 are controlled to move inward at the same time, continuing to press the two sides of the metal pipe, thereby increasing the bending degree of the metal pipe.

[0059] When a metal pipe with an inclined side needs to be bent, the electric push rod 403 is controlled to retract, driving the tooth block 404 to move upwards and interlock with the tooth groove 405, thereby constraining the cylindrical rod 407 from rotating. That is, the angle between the clamping pipe 305 and the adjusting rod 304 does not change at the beginning of the pipe bending. As the adjusting rod 304 continues to rotate, the two clamping pipes 305 become inclined inward, thereby making the middle part of the metal pipe protrude downward and the two sides inclined inward, so that another form of metal pipe can be processed, which is suitable for different needs.

[0060] After the bending process is completed, if the metal pipe is in a horizontal state, the two adjusting rods 304 are controlled to rotate downward to the lowest point at the same time, and the two sliding tables 106 move outward at the same time, then the metal pipe after bending can be unloaded automatically without manual operation. If the metal pipe is in an inclined state, the two clamping pipes 305 need to be manually detached from the top.

[0061] During the loading process, the electric push rod 403 can also be controlled to retract a small distance upward, but the tooth block 404 and the tooth groove 405 do not contact each other at this time, and the cylindrical rod 407 can rotate freely, that is, the angle of the clamping pipe 305 is no longer restricted. Then the height of the left clamping pipe 305 is controlled to be higher, while the height of the right clamping pipe 305 is controlled to be lower. At this time, the two clamping pipes 305 become inclined, and the metal pipe can slide along the clamping pipe 305 to the right side, reducing energy consumption and relying on gravity to complete the loading and unloading.

[0062] Through the coordinated operation of the adjusting rods 304, the sliding tables 106 and the electromagnet 412, precise control of the metal pipe processing process is achieved. In the initial positioning and center position adjustment stage, the metal pipe can be accurately moved to the specified position and the bending area is ensured to be in the center, so that the two clamping pipes 305 are at the same distance from the bending area. This precise operation ensures that the metal pipe is evenly stressed on both sides during bending, effectively avoiding the problem of poor bending effect caused by uneven stress, greatly improving the quality and precision of metal pipe bending, and meeting the scenes with high precision requirements for metal pipe processing.

[0063] When bending a metal pipe of a specific shape, the cooperation of the adjusting rods 304 and the sliding tables 106 realizes a unique bending method. During the bending process, the sliding tables 106 move from the outside to the inside, and the adjusting rods 304 gradually rotate upward, so that the position of the clamping pipe 305 moves from the outside to the inside. Not only does this increase the bending effect and rate, achieving secondary acceleration, but it also forms a labor-saving lever in the early stage of bending, reducing equipment wear and tear and facilitating stable bending. At the same time, by controlling the electric push rod 403, the angle of the clamping pipe 305 can be changed, and metal pipes of various shapes such as inclined sides can be processed, meeting the diverse needs of different customers for metal pipe shapes and enhancing the versatility and flexibility of the equipment.

[0064] In the loading and unloading links, the design is very convenient. For metal pipes in a horizontal state, the loading and unloading can be automatically completed by controlling the adjusting rods 304 and the sliding tables 106 without manual operation, saving manpower and time. During loading, the electric push rod 403 is controlled to retract a small distance, making the clamping pipe 305 inclined, and the metal pipe can slide along the clamping pipe 305 relying on gravity, reducing energy consumption and lowering processing costs. This convenient and labor-saving loading and unloading method improves the overall processing efficiency and makes the equipment more advantageous in production applications.
