Description

Technical Field

[0001] This invention relates to the field of metal sheet processing equipment technology, and in particular to a grooving device and method for processing color steel sheets. Background Technology

[0002] Color-coated steel sheet, also known as color-coated steel sheet, is a composite sheet made of cold-rolled or galvanized steel strip as substrate, which is pre-treated on the surface, then coated with organic paint and baked to cure. It is widely used in clean rooms, prefabricated houses, color-coated steel composite air ducts, building envelopes and other fields. In the deep processing of color-coated steel sheet, grooving is a key pre-process to realize the subsequent processes such as sheet bending, splicing and installation, and air duct manufacturing. Its processing accuracy and efficiency directly affect the final product assembly quality and production efficiency.

[0003] Existing color steel plate grooving equipment mostly adopts a single-blade fixed station structure, which makes grooving position adjustment cumbersome and difficult to adapt to different width plates and diverse groove spacing requirements. Some multi-blade equipment has each blade holder driven independently, resulting in poor synchronization and problems such as asymmetrical groove positions and inconsistent groove depths. In terms of plate positioning, traditional equipment usually uses manual adjustment of the limit baffles on both sides, which has low operating efficiency and difficulty in ensuring centering accuracy. It is impossible to achieve synchronous opposite movement of the limit baffles on both sides, and the adjustment workload is large when frequently changing production.

[0004] In terms of material conveying, existing grooving equipment mostly uses friction feeding with conveyor rollers or manual pushing. For long color steel plates, problems such as plate movement and positioning deviation are prone to occur during the conveying process. Moreover, the switching between the conveying and grooving processes requires manual intervention, making it difficult to achieve automated continuous production. Some equipment that uses a clamping and pulling structure has a clamping mechanism that is mostly driven on one side. The opening and closing of the upper and lower clamping plates are not synchronized, which can easily cause plate deviation or uneven surface indentation. Furthermore, there is a lack of linkage between the clamping mechanism and the positioning mechanism, which requires independent control. The control system is complex and the processing cycle is long.

[0005] Therefore, there is an urgent need to develop a color steel plate processing and grooving device with synchronous centering and limiting, positioning and conveying linkage, and independent adjustable grooving on both sides, in order to solve the technical problems of low positioning accuracy, cumbersome adjustment, insufficient automation and limited processing efficiency in the existing technology. Summary of the Invention

[0006] The main objective of this invention is to provide a grooving device and method for processing color steel plates, which can effectively solve the problems that existing grooving equipment mostly uses conveyor roller friction feeding or manual pushing, which can easily cause problems such as plate movement and positioning deviation during the conveying process for long color steel plates. Furthermore, the switching between the conveying and grooving processes requires manual intervention, making it difficult to achieve automated continuous production.

The inner cavities of the two hydraulic components I are connected by two hydraulic pipes. A limiting plate I is provided on the end face of the extension rod of the two hydraulic components I. The two limiting plates I are adapted to the conveying mechanism and are slidably installed in the inner wall of the conveying mechanism.

[0010] Preferably, the positioning device includes a hydraulic cylinder three, which is slidably mounted on the upper part of the fixed frame. The output end of the hydraulic cylinder three is provided with a limit plate two. One side of the outer surface of the hydraulic cylinder three is provided with a mounting plate one. The lower part of the mounting plate one is fixedly connected to the middle part of the corresponding limit plate one. The upper end of the mounting plate one is provided with a hydraulic component two. The end face of the extension rod of the hydraulic component two is provided with a connecting handle. The connecting handle is fixedly mounted on the extension end of the hydraulic cylinder three.

[0011] Preferably, the pushing device includes two hydraulic cylinders, which are fixedly installed in the middle of the worktable. The output ends of the two hydraulic cylinders are provided with connecting plates. The upper end of the connecting plate is provided with a clamping mechanism, and the lower end of the connecting plate is provided with a support leg. A limit roller is provided on the outer surface of the connecting plate away from the conveying mechanism. The upper part of the limit roller is flush with the upper part of the roller on the conveying mechanism.

[0012] Preferably, the clamping mechanism includes a positioning frame, which is fixedly installed on the upper end of the connecting plate. Mounting plates two are slidably installed on both the upper and lower sides of the middle part of the positioning frame. Clamping plates are provided on the side of the outer surface of the two mounting plates two that are close to each other. Hydraulic components four are provided on both sides of the upper part of the positioning frame. The extension rods of the two hydraulic components four are fixedly connected to the upper end of the mounting plate two located at the upper part. Pushing components are provided on both sides of the outer surface of the positioning frame.

[0013] Preferably, the inner cavities of the two hydraulic components four are respectively connected to the inner cavities of the two hydraulic components two via hydraulic pipes.

[0014] Preferably, the pusher includes two racks, which are slidably mounted on the inner surface of the positioning frame. The two racks are respectively fixedly connected to the outer surfaces of the two mounting plates. A gear is meshed between the two racks, and the gear is rotatably mounted on the outer surface of the positioning frame.

[0015] The present invention also discloses a method for using the above-mentioned grooving device for processing color steel sheets, the specific steps of which are as follows: S1. According to the width specifications and grooving position requirements of the color steel plate to be processed, adjust the lateral distance between the two grooving components on the upper part of the workbench so that the lateral coordinates of the grooving mechanisms on both sides are aligned with the target groove to complete the rough positioning. Then, according to the thickness specifications and grooving depth requirements of the color steel plate, set the motion coordinates of the lateral conveying mechanism and the longitudinal conveying mechanism as well as the feed stroke parameters of hydraulic cylinder one in the control system. At the same time, drive hydraulic cylinder two to output, and drive the two limit plates one to move synchronously through the hydraulic synchronization circuit to adjust the distance between them so that it matches the width of the color steel plate. During this process, limit plate one drives hydraulic cylinder three to move synchronously laterally along the fixed frame through mounting plate one, so that limit plate two automatically aligns to the top of the corresponding side without separate adjustment. S2. The color steel plate to be processed is inserted from one side of the pushing device, passes through the upper part of the limiting roller and the middle part of the clamping mechanism in sequence, and is placed on the upper roller surface of the conveying mechanism. The limiting roller forms rolling support for the extended section of the color steel plate to ensure the levelness of the plate. In the initial state, the upper and lower clamping plates of the clamping mechanism are in the open state, and the color steel plate can be smoothly inserted. S3. The second hydraulic cylinder outputs and pushes the first limit plate on the same side to move inward. The first limit plate on this side compresses the first hydraulic component on the corresponding side, so that the hydraulic oil flows into the inner cavity of the first hydraulic component on the other side through the hydraulic pipeline, thereby pushing the first limit plate on the other side to move inward in sync. The two limit plates on both sides move towards each other at the same speed, pushing the color steel plate to the center position of the worktable, completing the centering and lateral limiting of the color steel plate. S4. The three hydraulic cylinders on both sides output synchronously, driving the limit plate two to move downward and press against the upper surface of the color steel plate on both sides to achieve vertical positioning and prevent the plate from warping or shifting during the grooving process. At the same time, the hydraulic cylinder three extends downward and drives the extension rod of the hydraulic component two to compress downward synchronously through the connecting handle, so that the hydraulic oil in the inner cavity of the hydraulic component two is transported to the inner cavity of the hydraulic component four through the hydraulic pipeline. The hydraulic component four then retracts and pulls the upper mounting plate two upward. The upper mounting plate two drives the gear to rotate through the rack and pinion, synchronously driving the lower rack to move in the opposite direction and driving the lower mounting plate two downward, so that the upper and lower mounting plates two separate synchronously in the opposite direction, driving the upper and lower clamping plates to open synchronously. The clamping mechanism releases the clamping and fixing of the color steel plate, preparing for the subsequent material pulling stroke. S5. The horizontal conveying mechanism and the vertical conveying mechanism work together to drive the mounting frame and the grooving mechanism on it to move in two dimensions in the horizontal and vertical directions, and move precisely to the preset grooving coordinate position. Then, the hydraulic cylinder outputs to drive the grooving mechanism to feed downward along the mounting frame, so that the rotating grooving tool cuts into the color steel plate to the set depth. Then, the vertical conveying mechanism drives the grooving mechanism to move at a constant speed along the longitudinal direction of the plate to complete the grooving of the current station. According to the processing requirements, the grooving components on both sides can run synchronously to achieve double grooving, or they can run separately to achieve single-sided grooving. S6. After the current workstation's grooving is completed, hydraulic cylinder one retracts in the reverse direction, causing the grooving mechanism to lift the cutter upwards and detach it from the surface of the color steel plate. Hydraulic cylinder three then retracts in the reverse direction, causing limit plate two to move upwards to release the vertical pressure on the color steel plate. Simultaneously, hydraulic cylinder three retracts upwards, driving the extension rod of hydraulic component two upwards through the connecting handle. This causes the hydraulic oil in the inner cavity of hydraulic component four to flow back into the inner cavity of hydraulic component two. Under negative pressure, hydraulic component four extends and pushes the upper mounting plate two downwards. Through the synchronous transmission of gears and racks, the lower side... The mounting plate moves upward synchronously, and the upper and lower clamping plates close synchronously to clamp the color steel plate. Then, the hydraulic cylinder retracts in the opposite direction, driving the two limit plates to move outward synchronously, releasing the lateral limit on the color steel plate. The hydraulic cylinder outputs in the opposite direction, pulling the connecting plate to move closer to the conveying mechanism. The clamping mechanism clamps the color steel plate and moves synchronously, so that the unprocessed part of the color steel plate is pulled into the processing station, completing one step feeding. During this process, the support leg moves along the ground to support the connecting plate, and the limit roller continuously lifts the color steel plate to ensure it is horizontal. S7. After the step feeding is completed, the process cycle of lateral centering limit, vertical clamping and positioning, grooving processing and step feeding is repeated until all grooves in the entire length of the color steel plate are processed. In each cycle, the positioning device and the clamping mechanism are hydraulically linked to achieve alternating clamping, ensuring that the plate is reliably fixed by the positioning device during grooving processing and stably clamped by the clamping mechanism during feeding. The two are seamlessly connected to achieve continuous automated processing. S8. After all slots are processed, hydraulic cylinder three drives limit plate two to lift, and hydraulic cylinder two drives limit plate one to retract. The clamping mechanism maintains the clamping state. Then, hydraulic cylinder four continues to extend outward to gradually push the finished color steel plate out of the conveying mechanism. The staff receives and unloads the material at the discharge end. Finally, the parameters are readjusted according to the specifications and slot requirements of the next batch of plates to be processed, in preparation for the next round of processing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In this invention, grooving components are symmetrically arranged on both sides of the upper end of the worktable. Each grooving component can slide and adjust its position along the horizontal direction of the worktable, which can adapt to the processing requirements of color steel plates with different widths and different groove spacings. At the same time, the two grooving components can operate synchronously to achieve double-grooving processing, or they can operate independently to meet the processing requirements of single-sided grooving or asymmetrical grooves. It can adapt to diverse production needs without changing tooling, significantly improving the process adaptability and usage flexibility of the equipment, and reducing the time for production changeover. Each grooving component integrates a horizontal conveying mechanism and a vertical conveying mechanism, which can achieve two-dimensional precise positioning of the grooving mechanism, and control the vertical feed depth through a hydraulic cylinder. The grooving position and depth accuracy are controllable, and the processing quality is stable.

[0017] In this invention, the limiting device uses a single hydraulic cylinder to drive a single-sided limiting plate, and through a hydraulic synchronization circuit composed of two hydraulic components, drives the other-sided limiting plate to move in the opposite direction synchronously, so as to achieve synchronous centering and clamping of the two limiting plates. This hydraulic synchronization structure does not require a dual-cylinder synchronization control system. It can achieve synchronous centering of the two limiting plates by driving with only a single hydraulic cylinder. The structure is simple and reliable, with high centering accuracy, effectively avoiding lateral displacement of the color steel plate and ensuring the symmetry of the slotted position.

[0018] In this invention, the positioning device and the pushing device are linked through a closed-loop hydraulic circuit composed of hydraulic component two and hydraulic component four. When the positioning device presses the color steel plate, the clamping mechanism releases synchronously; conversely, when the positioning device releases, the clamping mechanism clamps synchronously. The two work alternately in conjunction with the pushing and pulling action of hydraulic cylinder four to achieve step-by-step continuous grooving processing. The automatic cycle of pressing, grooving, releasing, and pulling can be completed without the need for an additional electrical control system. This simplifies the control system, shortens the processing cycle, improves production efficiency, and reduces equipment manufacturing costs and maintenance difficulty. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figures 1-14As shown, this embodiment discloses a grooving device for processing color steel plates, including a workbench 1, a conveying mechanism 2 at the upper end of the workbench 1, grooving components 3 slidably installed on both sides of the upper end of the workbench 1, a limiting device 4 at the middle of the upper end of the workbench 1, positioning devices 5 on both sides of the upper part of the limiting device 4, and a pushing device 6 on one side of the outer surface of the workbench 1.

[0023] Specifically, during the grooving operation of the color steel plate, the worker first passes the color steel plate through the pushing device 6 and places it on the upper part of the conveying mechanism 2. Then, the limiting device 4 limits the color steel plate laterally, and then the positioning device 5 vertically presses and positions the color steel plate. After the positioning device 5 reliably limits the color steel plate, the grooving components 3 on both sides can perform the grooving operation on the color steel plate.

[0024] Furthermore, after the grooving components 3 on both sides complete the grooving processing of a certain position of the color steel plate, the pushing device 6 pushes the color steel plate to move longitudinally, so that the unprocessed part of the color steel plate enters the processing station. During this process, the positioning device 5 and the pushing device 6 achieve alternating clamping and releasing through hydraulic linkage to ensure the continuity of the conveying process and the positioning accuracy.

[0025] Furthermore, before the grooving component 3 performs grooving operations on the color steel plate, the operator can adjust the lateral position of the two grooving components 3 to adapt to the processing requirements of color steel plates with different widths and different groove spacings. In addition, according to the actual processing requirements of the color steel plate, the two grooving components 3 can operate synchronously to achieve double-grooving processing, or they can operate independently to meet the processing requirements of single-sided grooving or asymmetrical grooves, thus having strong process adaptability.

[0026] To achieve multi-dimensional adjustment of the slotting position and precise feeding, such as Figure 3 and Figure 4 As shown, the grooving component 3 includes a mounting frame 31, which is slidably mounted on the upper end of the workbench 1. Horizontal conveying mechanisms 32 are provided on both sides of the upper part of the mounting frame 31. Vertical conveying mechanisms 33 are provided below the two horizontal conveying mechanisms 32. Mounting frames 34 are provided below the two vertical conveying mechanisms 33. Hydraulic cylinders 35 are provided on the inner surfaces of the two mounting frames 34. Grooving mechanisms 36 are slidably mounted on the outer surfaces of the two mounting frames 34. The output ends of the two hydraulic cylinders 35 are fixedly connected to the lower parts of the two grooving mechanisms 36, respectively.

[0027] Specifically, during the grooving operation of the color steel plate, the staff first adjusts the horizontal position of the mounting frame 31 on the upper end of the workbench 1 according to the grooving position requirements to complete the rough positioning. Then, the horizontal conveying mechanism 32 and the vertical conveying mechanism 33 work together to drive the mounting frame 34 fixed at the lower part of the vertical conveying mechanism 33 and the grooving mechanism 36 on it to move to the target processing coordinates. Then, the hydraulic cylinder 35 outputs to drive the grooving mechanism 36 to feed downward, so that the grooving mechanism 36 performs the grooving operation on the color steel plate at the set depth.

[0028] To achieve centering and limiting of the color steel plate and ensure synchronization of the limiting on both sides, such as Figure 5 and Figure 6 As shown, the limiting device 4 includes a fixed frame 41, which is fixedly installed on the upper end of the workbench 1. A hydraulic cylinder 42 is provided on the lower part of one side of the outer surface of the fixed frame 41. A hydraulic component 44 is provided on the upper part of both sides of the outer surface of the fixed frame 41. The inner cavities of the two hydraulic components 44 are connected by two hydraulic pipes. A limiting plate 43 is provided on the end face of the extension rod of the two hydraulic components 44. The two limiting plates 43 are adapted to the conveying mechanism 2 and are slidably installed in the inner wall of the conveying mechanism 2. The output end of the hydraulic cylinder 42 is fixedly connected to the middle of the limiting plate 43 located on the same side.

[0029] Specifically, after the color steel plate is placed on the upper part of the conveying mechanism 2, the hydraulic cylinder 2 42 outputs and drives the limit plate 43 connected to it to move inward. During this process, the limit plate 43 simultaneously drives the hydraulic component 44 on the side close to the hydraulic cylinder 2 42 to compress. The hydraulic oil in the inner cavity of the hydraulic component 44 on this side is transported to the inner cavity of the hydraulic component 44 on the other side through the hydraulic pipe, pushing the hydraulic component 44 on the side away from the hydraulic cylinder 2 42 to extend, thereby pushing the limit plate 43 on the other side to move inward synchronously. Thus, the two limit plates 43 move towards each other synchronously, completing the centering and limiting of the color steel plate.

[0030] Furthermore, after the grooving component 3 completes the grooving processing of the current station of the color steel plate, the pushing device 6 needs to transport the color steel plate so that the subsequent station can enter the processing area. During this process, the hydraulic cylinder 42 outputs in the reverse direction and pulls the limiting plate 43 outward, so that the two limiting plates 43 release the lateral limitation on the color steel plate, so that the pushing device 6 can smoothly transport the color steel plate.

[0031] To achieve vertical pressing and positioning of the color steel plate and synchronize it with the limiting device, such as... Figures 7-9As shown, the positioning device 5 includes a hydraulic cylinder 3 51, which is slidably mounted on the upper part of the fixed frame 41. The output end of the hydraulic cylinder 3 51 is provided with a limit plate 2 52. One side of the outer surface of the hydraulic cylinder 3 51 is provided with a mounting plate 1 54. The lower part of the mounting plate 1 54 is fixedly connected to the middle part of the corresponding limit plate 1 43. The upper end of the mounting plate 1 54 is provided with a hydraulic component 2 53. The end face of the extension rod of the hydraulic component 2 53 is provided with a connecting handle 531, which is fixedly mounted on the extension end of the hydraulic cylinder 3 51.

[0032] Specifically, after the color steel plate is transported to the corresponding processing position, the hydraulic cylinder 3 51 outputs and drives the limiting plate 2 52 to move downward, so that the limiting plate 2 52 is pressed against the upper surface of the color steel plate to achieve vertical positioning and prevent the plate from warping or shifting during the grooving process.

[0033] Furthermore, during the process of hydraulic cylinder 2 42 driving limit plate 1 43 to move laterally, limit plate 1 43 drives hydraulic cylinder 3 51 to move laterally synchronously along the fixed frame 41 through mounting plate 1 54. This linkage structure can avoid the need for the operator to adjust the lateral position of the two hydraulic cylinders 3 51 separately, so that the two hydraulic cylinders 3 51 can automatically and synchronously move with the centering adjustment of the two limit plates 1 43, ensuring that limit plate 2 52 is always directly above the corresponding side.

[0034] Furthermore, during the downward movement of the limiting plate 52 driven by the output of hydraulic cylinder 3 51, the extension rod of hydraulic component 2 53 moves synchronously with the extension end of hydraulic cylinder 3 51 through connecting handle 531. Since hydraulic component 2 53 and clamping mechanism 63 in pushing device 6 are linked through hydraulic pipeline, when hydraulic cylinder 3 51 drives limiting plate 2 52 to press the color steel plate, hydraulic component 2 53 synchronously triggers clamping mechanism 63 in pushing device 6 to release clamping of color steel plate. Conversely, when positioning device 5 releases the pressing state of color steel plate, clamping mechanism 63 in pushing device 6 synchronously clamps color steel plate. The two work alternately to achieve continuous feeding.

[0035] Example 2: This example further improves the pushing device 6 based on Example 1, such as... Figures 10-12 As shown, the pushing device 6 includes two hydraulic cylinders 61, which are fixedly installed in the middle of the workbench 1. The output ends of the two hydraulic cylinders 61 are provided with connecting plates 62. The upper end of the connecting plate 62 is provided with a clamping mechanism 63, and the lower end of the connecting plate 62 is provided with a support leg 64. The outer surface of the connecting plate 62 away from the conveying mechanism 2 is provided with a limiting roller 65. The upper part of the limiting roller 65 is flush with the upper part of the roller on the conveying mechanism 2.

[0036] Specifically, when the positioning device 5 is in a pressing and fixing state on the color steel plate, the two slotting components 3 are in a slotting operation state, and the clamping mechanism 63 releases the clamping of the color steel plate under the hydraulic linkage of the hydraulic component 53. At this time, the hydraulic cylinder 61 outputs to drive the connecting plate 62 to move away from the conveying mechanism 2. During this process, the support leg 64 moves along the ground and forms vertical support for the connecting plate 62 to ensure the stability of the movement.

[0037] Furthermore, as the hydraulic cylinder 61 outputs and drives the connecting plate 62 to move away from the conveying mechanism 2, the connecting plate 62 drives the clamping mechanism 63 to move synchronously, so that the length of the suspended section of the color steel plate between the clamping mechanism 63 and the conveying mechanism 2 gradually increases, which is a reserve stroke for the next material feeding.

[0038] Furthermore, after the grooving component 3 completes the grooving processing of the color steel plate at the current workstation, the positioning device 5 releases the vertical clamping of the color steel plate. At this time, the hydraulic component 53 synchronously triggers the clamping mechanism 63 to clamp the color steel plate. Then, the hydraulic cylinder 61 outputs in the reverse direction, driving the connecting plate 62 to move towards the side closer to the conveying mechanism 2, thereby pulling the color steel plate along the longitudinal direction and allowing the unprocessed part of the color steel plate to enter the processing station. Subsequently, the positioning device 5 clamps the color steel plate again, and the hydraulic cylinder 61 drives the connecting plate 62 to move outward and reset again. This cycle is used to realize the step-by-step continuous grooving processing.

[0039] Furthermore, the limiting roller 65 can provide auxiliary support for the color steel plate extending from the worktable. Since the roller surface of the limiting roller 65 is flush with the roller surface of the conveying mechanism 2, when the hydraulic cylinder 61 pushes the connecting plate 62 to move outward, the limiting roller 65 first contacts the lower surface of the color steel plate and forms continuous support, effectively preventing the long color steel plate from sagging and deforming due to its own weight, and ensuring the straightness of the plate feeding process.

[0040] To achieve hydraulic linkage and synchronous opening and closing between the clamping mechanism and the positioning device, such as Figure 13 As shown, the clamping mechanism 63 includes a positioning frame 631, which is fixedly installed on the upper end of the connecting plate 62. Mounting plates 632 are slidably installed on both the upper and lower sides of the middle part of the positioning frame 631. Clamping plates 633 are provided on the side of the outer surface of the two mounting plates 632 that are close to each other. Hydraulic components 634 are provided on both sides of the upper part of the positioning frame 631. The extension rods of the two hydraulic components 634 are fixedly connected to the upper end of the mounting plate 632 located at the upper part. Pushing components 635 are provided on both sides of the outer surface of the positioning frame 631.

[0041] Furthermore, the inner cavities of the two hydraulic components 634 are respectively connected to the inner cavities of the two hydraulic components 53 via hydraulic pipes.

[0042] Specifically, when hydraulic cylinder 3 51 outputs and drives limit plate 2 52 to press down on the color steel plate, hydraulic cylinder 3 51 simultaneously drives the extension rod of hydraulic component 2 53 to compress downward, reducing the internal volume of hydraulic component 2 53. Hydraulic oil flows into the internal cavity of hydraulic component 4 634 through the hydraulic pipeline. During this process, the extension rod of hydraulic component 4 634 retracts and pulls the upper mounting plate 2 632 upward. At the same time, pusher 635 simultaneously drives the lower mounting plate 2 632 downward, causing the two mounting plates 2 632 to separate synchronously in opposite directions, thereby releasing the clamping mechanism 63 from clamping and fixing the color steel plate.

[0043] Furthermore, since there are differences in the thickness specifications and surface grooves of color steel plates, the staff can replace the clamping plate 633 according to the actual processing needs, and select clamping plates with different hardness, different tooth shape or different contact surface shape to adapt to color steel plates with different materials and different surface conditions, so as to ensure the reliability of clamping while avoiding damage to the surface coating of the plate.

[0044] To achieve synchronous reverse movement of the upper and lower clamping plates and ensure uniform distribution of clamping force, such as Figure 14 As shown, the pusher 635 includes two racks 6351, which are slidably mounted on the inner surface of the positioning frame 631. The two racks 6351 are fixedly connected to the outer surfaces of the two mounting plates 632 respectively. A gear 6352 is meshed between the two racks 6351, and the gear 6352 is rotatably mounted on the outer surface of the positioning frame 631.

[0045] Specifically, when the hydraulic component 634 drives the upper mounting plate 632 to move vertically, the mounting plate 632 drives the upper rack 6351 fixed to it to move synchronously. The upper rack 6351 drives the gear 6352 in the middle to rotate through tooth meshing. The gear 6352 then drives the lower rack 6351 to move in the opposite direction, so that the lower rack 6351 drives the lower mounting plate 632 to move synchronously in the opposite direction. This gear and rack synchronous structure ensures that the upper and lower clamping plates 633 always open and close symmetrically with the neutral surface of the color steel plate as the reference, and the clamping force is evenly distributed on the upper and lower surfaces of the plate, effectively avoiding plate displacement or uneven surface indentation caused by unilateral clamping.

[0046] Example 3 This application also discloses a method for using a grooving device for processing color steel sheets, the specific steps of which are as follows: S1. According to the width specifications and grooving position requirements of the color steel plate to be processed, adjust the lateral spacing of the two grooving components 3 on the upper end of the worktable 1 so that the lateral coordinates of the two grooving mechanisms 36 are aligned with the target groove to complete the rough positioning. Then, according to the thickness specifications and grooving depth requirements of the color steel plate, set the motion coordinates of the lateral conveying mechanism 32 and the longitudinal conveying mechanism 33 and the feed stroke parameters of the hydraulic cylinder 1 35 in the control system. At the same time, drive the output of the hydraulic cylinder 2 42, and drive the two limit plates 1 43 to move synchronously through the hydraulic synchronization circuit to adjust the distance between them so that they are adapted to the width of the color steel plate. During this process, the limit plate 1 43 drives the hydraulic cylinder 3 51 to move synchronously laterally along the fixed frame 41 through the mounting plate 1 54, so that the limit plate 2 52 is automatically aligned to the top of the corresponding side without separate adjustment. S2. The color steel plate to be processed is inserted from one side of the pushing device 6, passes through the upper part of the limiting roller 65 and the middle part of the clamping mechanism 63 in sequence, and is placed on the upper roller surface of the conveying mechanism 2. The limiting roller 65 forms rolling support for the extended section of the color steel plate to ensure the levelness of the plate. In the initial state, the upper and lower clamping plates 633 of the clamping mechanism 63 are in the open state, and the color steel plate can be smoothly inserted. S3, hydraulic cylinder 42 outputs and pushes the same-side limit plate 43 to move inward. The limit plate 43 on this side compresses the corresponding hydraulic component 44, so that hydraulic oil flows into the inner cavity of the other hydraulic component 44 through the hydraulic pipeline, thereby pushing the other limit plate 43 to move inward in sync. The two limit plates 43 on both sides move towards each other at the same speed, pushing the color steel plate to the center position of the worktable, completing the centering and lateral limiting of the color steel plate. S4. The two hydraulic cylinders 51 on both sides output synchronously, driving the limit plate 52 to move downward and press against the upper surface of the color steel plate on both sides to achieve vertical positioning and prevent the plate from warping or shifting during the grooving process. When the hydraulic cylinder 51 extends downward, it drives the extension rod of the hydraulic component 53 to compress downward synchronously through the connecting handle 531, so that the hydraulic oil in the inner cavity of the hydraulic component 53 is transported to the inner cavity of the hydraulic component 634 through the hydraulic pipeline. The hydraulic component 634 then retracts and pulls the upper mounting plate 632 upward. The upper mounting plate 632 drives the gear 6352 to rotate through the rack 6351, synchronously driving the lower rack 6351 to move in the opposite direction and driving the lower mounting plate 632 to move downward, so that the upper and lower mounting plates 632 separate synchronously in the opposite direction, driving the upper and lower clamping plates 633 to open synchronously. The clamping mechanism 63 releases the clamping and fixing of the color steel plate, preparing for the subsequent material pulling stroke. S5. The horizontal conveying mechanism 32 and the vertical conveying mechanism 33 work together to drive the mounting frame 34 and the grooving mechanism 36 on it to move in two dimensions in the horizontal and vertical directions, and move precisely to the preset grooving coordinate position. Then, the hydraulic cylinder 35 outputs to drive the grooving mechanism 36 to feed downward along the mounting frame 34, so that the rotating grooving tool cuts into the color steel plate to the set depth. Then, the vertical conveying mechanism 33 drives the grooving mechanism 36 to move at a constant speed along the longitudinal direction of the plate to complete the grooving processing of the current station. According to the processing requirements, the grooving components 3 on both sides can run synchronously to realize the processing of double grooves at the same time, or they can run independently to realize grooving on one side. S6. After the current workstation's grooving is completed, hydraulic cylinder 35 retracts in the reverse direction, driving the grooving mechanism 36 to lift the blade upwards and detach it from the surface of the color steel plate. Hydraulic cylinder 51 retracts in the reverse direction accordingly, driving the limiting plate 52 to move upwards to release the vertical pressure on the color steel plate. Simultaneously, as hydraulic cylinder 51 retracts upwards, it drives the extension rod of hydraulic component 53 to extend upwards synchronously through the connecting handle 531, causing the hydraulic oil in the inner cavity of hydraulic component 634 to flow back into the inner cavity of hydraulic component 53. Under negative pressure, hydraulic component 634 extends and pushes the upper mounting plate 632 downwards. Through the synchronous movement of gear 6352 and rack 6351... In the transmission, the lower mounting plate 632 moves upward synchronously, and the upper and lower clamping plates 633 close synchronously to clamp the color steel plate. Then, the hydraulic cylinder 42 retracts in the reverse direction, driving the two limit plates 43 to move outward synchronously, releasing the lateral limit on the color steel plate. The hydraulic cylinder 61 outputs in the reverse direction, pulling the connecting plate 62 to move closer to the conveying mechanism 2. The clamping mechanism 63 clamps the color steel plate and moves synchronously, so that the unprocessed part of the color steel plate is pulled into the processing station, completing one step feeding. During this process, the support leg 64 moves along the ground to support the connecting plate 62, and the limit roller 65 continuously lifts the color steel plate to ensure it is horizontal. S7. After the step feeding is completed, the process cycle of lateral centering limit, vertical clamping and positioning, grooving processing and step feeding is repeated until all grooves in the entire length of the color steel plate are processed. In each cycle, the positioning device 5 and the clamping mechanism 63 are hydraulically linked to achieve alternating clamping, ensuring that the plate is reliably fixed by the positioning device 5 during grooving processing and stably clamped by the clamping mechanism 63 during feeding. The two are seamlessly connected to achieve continuous automated processing. S8. After all slots are processed, hydraulic cylinder 3 51 drives limit plate 2 52 to lift, hydraulic cylinder 2 42 drives limit plate 1 43 to retract, and clamping mechanism 63 maintains clamping state. Then, hydraulic cylinder 4 61 continues to extend outward, gradually pushing the finished color steel plate out of the conveying mechanism 2. The staff receives and unloads the material at the discharge end. Finally, the parameters are readjusted according to the specifications and slot requirements of the next batch of plates to be processed, in preparation for the next round of processing.

According to the width specifications and grooving position requirements of the color steel plate to be processed, adjust the horizontal spacing of the two grooving components (3) on the upper end of the worktable (1) so that the horizontal coordinates of the two grooving mechanisms (36) are aligned with the target groove to complete the rough positioning. Then, according to the thickness specifications and grooving depth requirements of the color steel plate, set the motion coordinates of the horizontal conveying mechanism (32) and the longitudinal conveying mechanism (33) and the feed stroke parameters of the hydraulic cylinder one (35) in the control system. At the same time, drive the output of the hydraulic cylinder two (42) and drive the two limit plates one (43) to move synchronously through the hydraulic synchronous circuit to adjust the distance between them so that they are compatible with the width of the color steel plate. During this process, the limit plate one (43) drives the hydraulic cylinder three (51) to move synchronously along the fixed frame (41) through the mounting plate one (54) so ​​that the limit plate two (52) automatically aligns to the top of the corresponding side without separate adjustment. S2. The color steel plate to be processed is inserted from one side of the pushing device (6), passes through the upper part of the limiting roller (65) and the middle part of the clamping mechanism (63) in sequence, and is placed on the upper roller surface of the conveying mechanism (2). The limiting roller (65) forms rolling support for the extended section of the color steel plate to ensure the levelness of the plate. In the initial state, the upper and lower clamping plates (633) of the clamping mechanism (63) are in the open state, and the color steel plate can be smoothly inserted. S3, hydraulic cylinder two (42) outputs and pushes the same side limit plate one (43) to move inward. The limit plate one (43) of this side compresses the corresponding hydraulic component one (44) at the same time, so that the hydraulic oil flows into the inner cavity of the other side hydraulic component one (44) through the hydraulic pipeline, thereby pushing the other side limit plate one (43) to move inward at the same time. The two limit plates one (43) of both sides move towards each other at the same speed, pushing the color steel plate to the center position of the worktable, and completing the centering lateral limit of the color steel plate. S4. The two hydraulic cylinders (51) output synchronously, driving the limit plate (52) to move downward and press against the upper surface of the color steel plate on both sides to achieve vertical positioning and prevent the plate from warping or shifting during the grooving process. As the hydraulic cylinder (51) extends downward, it drives the extension rod of the hydraulic component (53) to compress downward synchronously through the connecting handle (531), so that the hydraulic oil in the inner cavity of the hydraulic component (53) is transported to the inner cavity of the hydraulic component (634) through the hydraulic pipeline. The hydraulic component (634) then... The upper mounting plate (632) is retracted and pulled upward. The upper mounting plate (632) drives the gear (6352) to rotate through the rack (6351), which synchronously drives the lower rack (6351) to move in the opposite direction and drives the lower mounting plate (632) to move downward. This causes the upper and lower mounting plates (632) to separate in the opposite direction synchronously, which drives the upper and lower clamping plates (633) to open synchronously. The clamping mechanism (63) releases the clamping and fixing of the color steel plate, preparing for the subsequent material pulling stroke. S5. The horizontal conveying mechanism (32) and the vertical conveying mechanism (33) work together to drive the mounting frame (34) and the grooving mechanism (36) on it to move in two dimensions in the horizontal and vertical directions, and move precisely to the preset grooving coordinate position. Then, the hydraulic cylinder (35) outputs to drive the grooving mechanism (36) to feed downward along the mounting frame (34), so that the rotating grooving tool cuts into the color steel plate to the set depth. Then, the vertical conveying mechanism (33) drives the grooving mechanism (36) to move at a uniform speed along the longitudinal direction of the plate to complete the grooving processing of the current station. According to the processing requirements, the grooving components (3) on both sides can run synchronously to realize the processing of double grooves at the same time, or they can run separately to realize grooving on one side. S6. After the current workstation has finished grooving, hydraulic cylinder one (35) retracts in the reverse direction, driving the grooving mechanism (36) to lift the blade upward and detach it from the surface of the color steel plate. Hydraulic cylinder three (51) retracts in the reverse direction, driving the limiting plate two (52) to move upward to release the vertical pressure on the color steel plate. At the same time as hydraulic cylinder three (51) retracts upward, it drives the extension rod of hydraulic component two (53) to stretch upward synchronously through the connecting handle (531), so that the hydraulic oil in the inner cavity of hydraulic component four (634) flows back to the inner cavity of hydraulic component two (53). Under the action of negative pressure, hydraulic component four (634) extends and pushes the upper mounting plate two (632) downward. Through the gear (6352) and rack (6351) Synchronous transmission, the lower mounting plate 2 (632) moves upward synchronously, and the upper and lower clamping plates (633) close synchronously to clamp the color steel plate. Then, the hydraulic cylinder 2 (42) retracts in the opposite direction, driving the two side limit plates 1 (43) to move outward synchronously, releasing the lateral limit on the color steel plate. The hydraulic cylinder 4 (61) outputs in the opposite direction, pulling the connecting plate (62) to move towards the side closer to the conveying mechanism (2). The clamping mechanism (63) clamps the color steel plate and moves synchronously, so that the unprocessed part of the color steel plate is pulled into the processing station, completing one step feeding. During this process, the support leg (64) moves along the ground to support the connecting plate (62), and the limit roller (65) continuously lifts the color steel plate to ensure horizontality. S7. After the step feeding is completed, the process cycle of lateral centering limit, vertical clamping and positioning, grooving processing and step feeding is repeated until all grooves in the entire length of the color steel plate are processed.

The two are seamlessly connected to achieve continuous automated processing. S8. After all slots are processed, hydraulic cylinder three (51) drives limit plate two (52) to lift, hydraulic cylinder two (42) drives limit plate one (43) to retract, clamping mechanism (63) maintains clamping state, and then hydraulic cylinder four (61) continues to extend outward to gradually push the finished color steel plate out from the conveying mechanism (2). The staff receives and completes the unloading at the discharge end. Finally, the parameters are readjusted according to the specifications and slot requirements of the next batch of plates to be processed, and the next round of processing is prepared.
