Description

Technical Field

[0001] The present invention relates to the technical field of sound barrier panel processing, and specifically to a processing device for producing arc-shaped sound barrier panels. Background Art

[0002] For wind-resistant arc-shaped sound barrier panels, the sound barrier panels usually use an overall arc or a top arc. The acting force of the wind on the panel is converted into the axial pressure of the panel through the arc-shaped curved surface to improve the wind resistance.

[0003] The arc-shaped sound barrier panel needs to be processed with louver holes. The required thickness of the sound barrier panel is different under different usage conditions, and the punching depth of the louver holes affects the wind resistance of the sound barrier panel. If the punching is too deep, the effective load-bearing cross-sectional area of the sound barrier panel will be reduced, resulting in a decrease in bending stiffness and wind pressure resistance, which may cause deformation or fracture. If the punching is too shallow, it will affect the efficiency of sound entering the sound-absorbing material of the sound barrier panel, resulting in a decrease in sound insulation effect. The traditional processing device needs to replace different dies to adjust the punching depth, resulting in a decrease in processing efficiency, and cannot adaptively adjust the punching depth according to the thickness of the plate, and cannot ensure the processing quality of the sound barrier panel. Summary of the Invention

[0004] The purpose of the present invention is to provide a processing device for producing arc-shaped sound barrier panels to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A processing device for producing arc-shaped sound barrier panels, the processing device includes a conveying mechanism, a positioning mechanism, a punching mechanism, a bending mechanism and a collection box. The conveying mechanism and the positioning mechanism are fixedly connected, the conveying mechanism and the punching mechanism are fixedly connected, the punching mechanism and the bending mechanism are fixedly connected, and the conveying mechanism, the punching mechanism, the bending mechanism and the collection box are arranged in sequence along the processing direction;

[0007] The punching mechanism includes a fixed frame, a hydraulic cylinder, a mounting plate, a fixing unit, a connecting plate, a depth adjusting unit and a punching head. The fixed frame and the hydraulic cylinder are fixedly connected, the output end of the hydraulic cylinder and the mounting plate are fixedly connected.

[0008] The arc-shaped sound barrier panel to be processed is transported through a conveying mechanism to a positioning mechanism. After the positioning mechanism adjusts the position of the arc-shaped sound barrier panel, it is transported to a punching mechanism. Through a hydraulic cylinder fixed on a fixed frame, the output end of the hydraulic cylinder is fixed to a mounting plate, so that the hydraulic cylinder drives the mounting plate to move. The two fixing units are respectively fixed to the connecting plate and the mounting plate, so that the fixing units and the connecting plate move with the mounting plate. The plate to be processed is fixed by the two fixing units. At the same time, through a depth adjustment unit, the depth adjustment unit slides on the punching head to adjust the length of contact between the punching head and the plate, and adjust the punching depth of the punching head. The punching head is fixed to the connecting plate, so that the punching head moves with the connecting plate to punch the plate to be processed, and then louver holes are processed on the plate. After the punching process is completed, the subsequent plate pushes the processed plate to a bending mechanism. Through the bending mechanism, the punched plate is bent into an arc shape. The arc-shaped sound barrier panel after the bending process falls into a collection box for collection, realizing the automatic processing of the arc-shaped sound barrier panel.

[0009] Further, the depth adjustment unit includes a driving component, a transmission component, a first nut, a bearing, a screw rod, and a sliding plate. The driving component is in transmission connection with the transmission component, the transmission component is fixedly connected to the first nut, the inner ring of the first nut is fixedly connected to the bearing, the outer ring of the bearing is fixedly connected to the connecting plate, the first nut is in threaded connection with the screw rod, the sliding plate is fixedly connected to the screw rod, and the sliding plate is provided with an adjustment groove, and the adjustment groove is in sliding connection with the punching head.

[0010] The driving component and the transmission component are in gear transmission connection, so that the driving component drives the transmission component to work. The transmission component drives the first nut to rotate. Since the inner ring of the first nut is fixed to the bearing and the outer ring of the bearing is fixed to the connecting plate, the first nut rotates in place. The first nut is in threaded connection with the screw rod, and one end of the screw rod is fixed to the sliding plate, so that the first nut drives the screw rod to move, and then the screw rod drives the sliding plate to move. Through the adjustment groove provided on the sliding plate, the sliding plate slides on the punching head to adjust the length of contact between the punching head and the plate, and further adjust the punching depth, so as to ensure that the processed louver holes completely penetrate the plate, and at the same time prevent the punching head from pressing down excessively and damaging the arc structure of the louver holes.

[0011] Further, the driving component includes a first sliding rod, a first spring, a first fixing block, a first rack, a first gear, a transmission shaft, a second fixing block, a second rack, and a second gear. The connecting plate is provided with a first sliding groove, the first sliding rod is in sliding connection with the first sliding groove, one end of the first spring is fixedly connected to the connecting plate, the other end of the first spring is fixedly connected to the first fixing block, the first sliding rod is fixedly connected to the first fixing block, the first rack is fixedly connected to the first fixing block, the first gear is engaged with the first rack, the transmission shaft is in transmission connection with the first gear, the transmission shaft is rotatably connected to the second fixing block, the second fixing block is fixedly connected to the fixing unit, the second rack is engaged with the first gear, and the second rack is engaged with the second gear.

[0012] It is fixed by the second fixing block and the fixing unit. The two ends of the first spring are respectively fixed to the first fixing block and the connecting plate. The second rack is slidably connected to the connecting plate. The second rack is provided with a groove, which cooperates with the protrusion on the connecting plate, so that the second rack can only move linearly. The second rack meshes with the first gear. The first gear is installed on the second fixing block through a transmission shaft. The fixing unit moves with the connecting plate and stops moving after contacting the plate. The first fixing block continues to move driven by the first spring under the drive of the connecting plate until it moves to the fixing frame parallel to the bottom of the plate. At the same time, the first rack drives the first gear to rotate, the first gear drives the second rack to move upward, the second rack drives the second gear to rotate, and through the first slide bar and the first sliding groove, the first rack can only move linearly. After punching, the first rack is reset by the first spring.

[0013] Furthermore, the transmission assembly includes a lead screw, fixing plates, a second nut, a first guide rail, a third rack and a third gear. There are two fixing plates. The two fixing plates are rotatably connected to the lead screw. The two fixing plates are fixedly connected to the connecting plate. The second gear is in transmission connection with the lead screw. The second nut is threadedly connected to the lead screw. The second nut is slidably connected to the first guide rail. The third rack is fixedly connected to the second nut. The third gear meshes with the third rack. The third gear is in transmission connection with the first nut.

[0014] By providing two fixing plates, the two ends of the lead screw are rotatably connected to the fixing plates, and the fixing plates are fixed on the connecting plate, so that the lead screw is supported at both ends. The second gear and the lead screw are in transmission connection through a keyway, so that the second gear drives the lead screw to rotate. By the second nut being threadedly connected to the lead screw, the second nut slides along the first guide rail on the lead screw. By the third rack being fixed to the second nut, the third rack drives the third gear to rotate. The third gear and the first nut are in transmission connection through a keyway, so that the first nut rotates.

[0015] Furthermore, the fixing unit includes sleeves, second springs, second slide bars and fixing rods. There are two sleeves. The sleeves are provided with second sliding grooves. There are two second slide bars. The two second slide bars are respectively slidably connected to the two second sliding grooves. There are two second springs. The two second springs are respectively placed in the two second sliding grooves. The fixing rod is fixedly connected to the two second slide bars.

[0016] When the fixing rod contacts the plate, the connecting plate continues to move downward. By fixing the second slide bar to the fixing rod, the second slide bar slides into the second sliding groove of the sleeve, so that the second spring is compressed. Through the elastic force generated by the compression of the second spring, the fixing rod presses the plate tightly, thereby realizing the fixing of the plate.

[0017] Further, the bending mechanism includes a bracket, a first roller, a second roller, a linear module, a first bidirectional module, a support block, and a driving mechanism. The bracket is fixedly connected to the linear module. There are two first rollers and five support blocks. Each first roller is rotatably connected to two support blocks, and the second roller is rotatably connected to one support block. The linear module is fixedly connected to the bracket, and the sliding end of the linear module is fixedly connected to one support block. The first bidirectional module is fixedly connected to the bracket, and the two sliding ends of the first bidirectional module are respectively fixedly connected to two support blocks. The driving mechanism is fixedly connected to the bracket and is in transmission connection with the two first rollers.

[0018] Through the driving mechanism, the two first rollers are driven to rotate, so that the sound barrier panel to be bent moves on them, thereby bending the sound barrier panel under the action of the two first rollers and the second roller. Fixed by the bracket and the linear module, the sliding end of the linear module is fixed to one support block, and the support block is rotatably connected to the second roller, so that the support block supports the second roller. Fixed by the first bidirectional module and the two support blocks, the two support blocks fixed on the first bidirectional module are respectively rotatably connected to the two first rollers, and both ends of the first roller are rotatably connected to the support block, so that the support block supports the two first rollers, enabling the first bidirectional module to drive the two support blocks to move, thereby adjusting the distance between the two first rollers. The linear module drives the support block to move to adjust the vertical distance between the second roller and the midpoint of the two first rollers, thereby adjusting the bending radius of the sound barrier panel.

[0019] Further, the driving mechanism includes a motor, a synchronous belt, a rotating shaft, a slider, a second guide rail, a third spring, a third sliding rod, and a third fixing block. The motor is fixedly connected to the bracket. There are two rotating shafts. The output end of the motor is fixedly connected to the first rotating shaft. The synchronous belt is in transmission connection with the rotating shaft and is also in transmission connection with the first roller. The slider is rotatably connected to one rotating shaft. The second guide rail is slidably connected to the slider. The third spring is fixedly connected to the slider and is also fixedly connected to the third fixing block. The third fixing block is provided with a through hole, and the third sliding rod is slidably connected to the through hole and is fixedly connected to the slider.

[0020] The motor is fixed to the bracket through the machine base, and the output end of the motor is fixed to one rotating shaft, so that the motor drives the rotating shaft to rotate. The synchronous belt is sleeved between the two first rollers and the two rotating shafts. The first rollers and the rotating shafts are provided with tooth grooves that cooperate with the synchronous belt, so that the synchronous belt rotates, thereby driving the two first rollers to rotate. The slider is rotatably connected to one rotating shaft and adjusts the distance with the two first rollers, driving the slider to move up and down on the second guide rail. Through the third spring fixed to the slider and the third fixing block at both ends, the elastic force of the third spring provides a pre-tightening force for the slider. The third sliding rod passes through the third spring and slides on the through hole, so that the acting direction of the elastic force of the third spring is always perpendicular to the slider, ensuring that the synchronous belt always maintains a transmission connection.

[0021] Furthermore, the positioning mechanism includes a second bidirectional module and a limiting block. The second bidirectional module is fixedly connected to the conveying mechanism. There are two limiting blocks, and the two sliding ends of the second bidirectional module are respectively fixedly connected to the two limiting blocks.

[0022] Through the second bidirectional module fixed on the conveying mechanism, the two sliding ends of the second bidirectional module are respectively fixed to the two limiting blocks, so that the second bidirectional module drives the two limiting blocks to contact both sides of the plate respectively, thereby adjusting the position of the plate, and ensuring the accuracy of the punching position.

[0023] Furthermore, the first roller is provided with an annular groove.

[0024] By providing the annular groove on the first roller, the protruding part of the louver hole of the plate after the hole processing is located in the annular groove, protecting the processed louver hole and preventing damage to the processed louver hole when bending the plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. Through the depth adjustment unit, the punching depth is adaptively adjusted according to the thickness of the plate, thereby ensuring that the processed louver holes completely penetrate the plate, while preventing the punch from pressing down excessively and damaging the arc structure of the louver hole, thus ensuring the processing quality of the sound barrier panel, and there is no need to replace different molds due to the thickness of the plate, improving production efficiency.

[0027] 2. The plate is bent into an arc shape by the bending mechanism, and by adjusting the distance between the two first rollers and the vertical distance from the second roller to the first roller, the bending radius of the sound barrier panel is adjusted, thereby adapting to the bending processing of different plates.

[0028] 3. The first roller is provided with an annular groove, so that the protruding part of the louver hole of the plate after the hole processing is located in the annular groove, protecting the processed louver hole and preventing damage to the processed louver hole when bending the plate.

[0041] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment: As Figures 1-3 shown, the present invention provides a technical solution for a processing device for manufacturing an arc-shaped sound barrier panel. A processing device for manufacturing an arc-shaped sound barrier panel includes a conveying mechanism 1, a positioning mechanism 2, a punching mechanism 3, a bending mechanism 4, and a collection box 5. The conveying mechanism 1 and the positioning mechanism 2 are fixedly connected. The conveying mechanism 1 and the punching mechanism 3 are fixedly connected. The punching mechanism 3 and the bending mechanism 4 are fixedly connected. The conveying mechanism 1, the punching mechanism 3, the bending mechanism 4, and the collection box 5 are arranged in sequence along the processing direction.

[0043] The punching mechanism 3 includes a fixed frame 31, a hydraulic cylinder 32, a mounting plate 33, a fixing unit 34, a connecting plate 35, a depth adjustment unit 36, and a punching head 37. The fixed frame 31 and the hydraulic cylinder 32 are fixedly connected. The output end of the hydraulic cylinder 32 and the mounting plate 33 are fixedly connected. There are two fixing units 34. The two fixing units 34 and the mounting plate 33 are fixedly connected. The two fixing units 34 and the connecting plate 35 are fixedly connected. The depth adjustment unit 36 and the connecting plate 35 are fixedly connected. The punching head 37 and the connecting plate 35 are fixedly connected. The depth adjustment unit 36 and the punching head 37 are slidably connected.

[0044] The arc-shaped sound barrier panel to be processed is conveyed by the conveying mechanism 1 through the positioning mechanism 2. After the positioning mechanism 2 adjusts the position of the arc-shaped sound barrier panel, it is conveyed to the punching mechanism 3. Through the hydraulic cylinder 32 fixed on the fixed frame 31, the output end of the hydraulic cylinder 32 and the mounting plate 33 are fixed, so that the hydraulic cylinder 32 drives the mounting plate 33 to move. Through the two fixing units 34 being respectively fixed to the connecting plate 35 and the mounting plate 33, the fixing unit 34 and the connecting plate 35 move with the mounting plate 33. The plate to be processed is fixed by the two fixing units 34. At the same time, through the depth adjustment unit 36, the depth adjustment unit 36 slides on the punching head 37 to adjust the length of contact between the punching head 37 and the plate, and adjust the punching depth of the punching head 37. Through the punching head 37 and the connecting plate 35 being fixed, the punching head 37 moves with the connecting plate 35 to punch the plate to be processed, thereby processing louver holes on the plate. After the punching process is completed, the subsequent plate pushes the processed plate to the bending mechanism 4. Through the bending mechanism 4, the punched plate is bent into an arc shape. The arc-shaped sound barrier panel after the bending process falls into the collection box 5 for collection, realizing the automatic processing of the arc-shaped sound barrier panel.

[0045] As Figures 3-6As shown in the figure, the depth adjustment unit 36 includes a driving component 361, a transmission component 362, a first nut 363, a bearing 364, a screw rod 365, and a sliding plate 366. The driving component 361 and the transmission component 362 are in transmission connection. The transmission component 362 is fixedly connected to the first nut 363. The inner ring of the first nut 363 is fixedly connected to the inner ring of the bearing 364, and the outer ring of the bearing 364 is fixedly connected to the connecting plate 35. The first nut 363 is in threaded connection with the screw rod 365, and the sliding plate 366 is fixedly connected to the screw rod 365. The sliding plate 366 is provided with an adjustment groove 3661, and the adjustment groove 3661 is in sliding connection with the punching head 37.

[0046] The driving component 361 and the transmission component 362 are connected by gear transmission, so that the driving component 361 drives the transmission component 362 to work. The transmission component 362 drives the first nut 363 to rotate. Since the inner ring of the first nut 363 is fixed to the inner ring of the bearing 364 and the outer ring of the bearing 364 is fixed to the connecting plate 35, the first nut 363 rotates in place. The first nut 363 is in threaded connection with the screw rod 365, and one end of the screw rod 365 is fixed to the sliding plate 366, so that the first nut 363 drives the screw rod 365 to move. Furthermore, the screw rod 365 drives the sliding plate 366 to move. Through the adjustment groove 3661 provided on the sliding plate 366, the sliding plate 366 slides on the punching head 37, adjusting the length of the contact between the punching head 37 and the plate, and further adjusting the punching depth, so as to ensure that the processed louver holes completely penetrate the plate, and at the same time prevent the punching head from pressing down excessively and damaging the arc structure of the louver holes.

[0047] As Figure 5 and Figure 7 shown in the figure, the driving component 361 includes a first sliding rod 3611, a first spring 3612, a first fixing block 3613, a first rack 3614, a first gear 3615, a transmission shaft 3616, a second fixing block 3617, a second rack 3618, and a second gear 3619. The connecting plate 35 is provided with a first sliding groove 351, and the first sliding rod 3611 is in sliding connection with the first sliding groove 351. One end of the first spring 3612 is fixedly connected to the connecting plate 35, and the other end of the first spring 3612 is fixedly connected to the first fixing block 3613. The first sliding rod 3611 is fixedly connected to the first fixing block 3613. The first rack 3614 is fixedly connected to the first fixing block 3613. The first gear 3615 meshes with the first rack 3614. The transmission shaft 3616 is in transmission connection with the first gear 3615. The transmission shaft 3616 is rotatably connected to the second fixing block 3617. The second fixing block 3617 is fixedly connected to the fixing unit 34. The second rack 3618 meshes with the first gear 3615, and the second rack 3618 meshes with the second gear 3619.

[0048] It is fixed by the second fixing block 3617 and the fixing unit 34. The two ends of the first spring 3612 are respectively fixed to the first fixing block 3613 and the connecting plate 35. The second rack 3618 is slidably connected to the connecting plate 35. The second rack 3618 is provided with a groove, which cooperates with the protrusion on the connecting plate 35, so that the second rack 3618 can only move linearly. The second rack 3618 meshes with the first gear 3615. The first gear 3615 is installed on the second fixing block 3617 through the transmission shaft 3616. The fixing unit 34 moves with the connecting plate 35 and stops moving after contacting the plate. The first fixing block 3613 continues to move under the drive of the first spring 3612 driven by the connecting plate 35 until it moves to the fixing frame 31 parallel to the bottom of the plate. At the same time, the first rack 3614 drives the first gear 3615 to rotate. The first gear 3615 drives the second rack 3618 to move upward. The second rack 3618 drives the second gear 3619 to rotate. Through the first slide bar 3611 and the first sliding groove 351, the first rack 3614 can only move linearly. After punching, the first spring 3612 resets the first rack 3614.

[0049] As Figure 6 and Figure 8 shown in the figure, the transmission assembly 362 includes a lead screw 3621, fixing plates 3622, a second nut 3623, a first guide rail 3624, a third rack 3625 and a third gear 3626. There are two fixing plates 3622. The two fixing plates 3622 are rotatably connected to the lead screw 3621. The two fixing plates 3622 are fixedly connected to the connecting plate 35. The second gear 3619 is in transmission connection with the lead screw 3621. The second nut 3623 is threadedly connected to the lead screw 3621. The second nut 3623 is slidably connected to the first guide rail 3624. The third rack 3625 is fixedly connected to the second nut 3623. The third gear 3626 meshes with the third rack 3625. The third gear 3626 is in transmission connection with the first nut 363.

[0050] By providing two fixing plates 3622, the two ends of the lead screw 3621 are rotatably connected to the fixing plates 3622, and the fixing plates 3622 are fixed on the connecting plate 35, so that the lead screw 3621 is supported at both ends. The second gear 3619 and the lead screw 3621 are in transmission connection through a keyway, so that the second gear 3619 drives the lead screw 3621 to rotate. By threadedly connecting the second nut 3623 to the lead screw 3621, the second nut 3623 slides on the lead screw 3621 along the first guide rail 3624. By fixing the third rack 3625 to the second nut 3623, the third rack 3625 drives the third gear 3626 to rotate. The third gear 3626 and the first nut 363 are in transmission connection through a keyway, so that the first nut 363 rotates.

[0051] As Figure 2 and Figure 9As shown, the fixing unit 34 includes a sleeve 341, a second spring 342, a second sliding rod 343, and a fixing rod 344. There are two sleeves 341, and the sleeve 341 is provided with a second sliding groove 3411. There are two second sliding rods 343, and the two second sliding rods 343 are respectively slidably connected to the two second sliding grooves 3411. There are two second springs 342, and the two second springs 342 are respectively placed in the two second sliding grooves 3411. The fixing rod 344 is fixedly connected to the two second sliding rods 343.

[0052] By contacting the plate through the fixing rod 344, the connecting plate 35 continues to move downward. Through the second sliding rod 343 fixedly connected to the fixing rod 344, the second sliding rod 343 slides into the second sliding groove 3411 of the sleeve 341, compressing the second spring 342. Through the elastic force generated by the compression of the second spring 342, the fixing rod 344 presses the plate, thereby realizing the fixation of the plate.

[0053] As Figure 10 As shown, the bending mechanism 4 includes a bracket 41, a first roller 42, a second roller 43, a linear module 44, a first bidirectional module 45, a support block 46, and a driving mechanism 47. The bracket 41 is fixedly connected to the linear module 44. There are two first rollers 42, and there are five support blocks 46. Each first roller 42 is rotatably connected to two support blocks 46. The second roller 43 is rotatably connected to one support block 46. The linear module 44 is fixedly connected to the bracket 41. The sliding end of the linear module 44 is fixedly connected to one support block 46. The first bidirectional module 45 is fixedly connected to the bracket 41. The two sliding ends of the first bidirectional module 45 are respectively fixedly connected to the two support blocks 46. The driving mechanism 47 is fixedly connected to the bracket 41. The driving mechanism 47 is drivingly connected to the two first rollers 42.

[0054] Through the driving mechanism 47, the two first rollers 42 are driven to rotate, enabling the sound barrier panel to be bent to move thereon. Thus, the sound barrier panel is bent under the action of the two first rollers 42 and the second roller 43. Through the fixation of the bracket 41 and the linear module 44, the sliding end of the linear module 44 is fixedly connected to one support block 46, and the support block 46 is rotatably connected to the second roller 43, enabling the support block 46 to support the second roller 43. Through the fixation of the first bidirectional module 45 and the two support blocks 46, the two support blocks 46 fixed on the first bidirectional module 45 are respectively rotatably connected to the two first rollers 42. Both ends of the first roller 42 are rotatably connected to the support block 46, enabling the support block 46 to support the two first rollers 42, enabling the first bidirectional module 45 to drive the two support blocks 46 to move, thereby adjusting the distance between the two first rollers 42. Through the linear module 44 driving the support block 46 to move, the vertical distance between the second roller 43 and the midpoint of the two first rollers 42 is adjusted, thereby adjusting the bending radius of the sound barrier panel.

[0055] AsFigure 11 As shown in the figure, the driving mechanism 47 includes a motor 471, a synchronous belt 472, a rotating shaft 473, a slider 474, a second guide rail 475, a third spring 476, a third slide bar 477, and a third fixing block 478. The motor 471 is fixedly connected to the bracket 41. There are two rotating shafts 473. The output end of the motor 471 is fixedly connected to the first rotating shaft 473. The synchronous belt 472 is in transmission connection with the rotating shaft 473. The synchronous belt 472 is in transmission connection with the first roller 42. The slider 474 is rotatably connected to one rotating shaft 473. The second guide rail 475 is slidably connected to the slider 474. The third spring 476 is fixedly connected to the slider 474. The third spring 476 is fixedly connected to the third fixing block 478. The third fixing block 478 is provided with a through hole 4781. The third slide bar 477 is slidably connected to the through hole 4781. The third slide bar 477 is fixedly connected to the slider 474.

[0056] The motor 471 and the bracket 41 are fixed through the machine base. The output end of the motor 471 is fixed to one rotating shaft 473, so that the motor 471 drives the rotating shaft 473 to rotate. The synchronous belt 472 is sleeved between the two first rollers 42 and the two rotating shafts 473. The first roller 42 and the rotating shaft 473 are provided with tooth grooves that cooperate with the synchronous belt 472, so that the synchronous belt 472 rotates, and then drives the two first rollers 42 to rotate. The slider 474 is rotatably connected to one rotating shaft 473, adjusts the distance with the two first rollers 42, drives the slider 474 to move up and down on the second guide rail 475. The third spring 476 fixed to the slider 474 and the third fixing block 478 at both ends provides a pre-tightening force for the slider 474 by the elastic force of the third spring 476. The third slide bar 477 passes through the third spring 476, and the third slide bar 477 slides on the through hole 4781, so that the acting direction of the elastic force of the third spring 476 is always perpendicular to the slider 474, and the synchronous belt 472 is always kept in transmission connection.

[0057] As Figure 1 shown in the figure, the positioning mechanism 2 includes a second bidirectional module 21 and a limiting block 22. The second bidirectional module 21 is fixedly connected to the conveying mechanism 1. There are two limiting blocks 22. The two sliding ends of the second bidirectional module 21 are respectively fixedly connected to the two limiting blocks 22.

[0058] Through the second bidirectional module 21 fixed to the conveying mechanism 1, the two sliding ends of the second bidirectional module 21 are respectively fixed to the two limiting blocks 22, so that the second bidirectional module 21 drives the two limiting blocks 22 to contact both sides of the plate respectively, and then adjusts the position of the plate, thereby ensuring the accuracy of the punching position.

[0059] As Figure 10 shown in the figure, the first roller 42 is provided with an annular groove 421.

[0060] The first roller 42 is provided with an annular groove 421, so that the protruding parts of the louver holes of the processed plate are located in the annular groove 421, protecting the processed louver holes and preventing damage to the processed louver holes when bending the plate.

[0061] Working principle: The conveying mechanism 1 conveys the arc-shaped sound barrier panel to be processed. The second two-way module 21 drives the two limit blocks 22 to contact both sides of the plate respectively, thereby adjusting the position of the plate. The hydraulic cylinder 32 drives the mounting plate 33 to move, so that the fixed rod 344 contacts the plate. Through the elastic force generated by the compression of the second spring 342, the fixed rod 344 presses the plate tightly. At the same time, the driving component 361 and the transmission component 362 are connected by gear transmission, so that the driving component 361 drives the transmission component 362 to work, making the first nut 363 drive the screw rod 365 to move, and then driving the sliding plate 366 to move, adjusting the length of the contact between the punching head 37 and the plate, and then adjusting the punching depth, so as to ensure that the processed louver holes completely penetrate the plate, and at the same time prevent the punching head from pressing down excessively to damage the arc structure of the louver holes. After the punching process is completed, the subsequent plate pushes the processed plate to the bending mechanism 4. The second roller 43 presses down to contact the plate. The driving mechanism 47 drives the two first rollers 42 to rotate, driving the plate to move, and bending the plate into an arc shape. The processed arc-shaped sound barrier panel falls into the collection box 5 for collection, realizing the automatic processing of the arc-shaped sound barrier panel.
