Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of four-roll plate rolling machine, in particular to a full-automatic production four-roll plate rolling machine. BACKGROUND

[0002] The plate rolling machine is a key equipment for bending metal plates into arc or cylinder shape through rotating rollers, and is widely used in fields such as pressure vessels, ships, chemical industry and building steel structure manufacturing. Among them, the four-roll plate rolling machine has become the mainstream model of medium plate rolling because it has two side rollers that can be independently adjusted, and is superior to the three-roll plate rolling machine in pre-bending and centering.

[0003] However, the existing four-roll plate rolling machine still has a lot of room for improvement in terms of automation and intelligence, and has the following defects: Dependence on manual centering and experience operation: The centering (i.e. alignment) of the center line of the plate with the center line of the machine roller during feeding mainly depends on the visual inspection and manual adjustment of the operator. This not only has low production efficiency, but also has a large influence on the centering accuracy due to human factors. Once the centering is not accurate, it will cause defects such as misalignment and skew of the rolled cylinder, seriously affecting the quality of the finished product. The plate rolling process is a complex elastic-plastic deformation process. Most existing equipment lacks real-time online detection means for the bending curvature of the plate. The operator usually sets the pressing amount according to experience, and approaches the target curvature through repeated attempts of "trial bending - measurement - adjustment", resulting in long auxiliary time, large material waste, and difficulty in ensuring the consistency of batch products. The processes of feeding, centering, rolling and unloading are mostly independent units, and the degree of automation connection is insufficient, which cannot realize the "one-key" full-process automatic production in the true sense, restricting the overall efficiency of the production line. SUMMARY

[0004] The purpose of the present application is to provide a full-automatic production four-roll plate rolling machine to solve the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a full-automatic production four-roll plate rolling machine, comprising a feeding conveyor, a centering mechanism fixedly installed on the feeding conveyor, a four-roll plate rolling machine provided at one end of the feeding conveyor and close to the centering mechanism, a detection mechanism fixedly installed on the upper side of the four-roll plate rolling machine, and a discharging conveyor provided at the discharging end of the four-roll plate rolling machine. The four-roll plate rolling machine comprises a bottom plate, a main rolling assembly, a support, a secondary rolling assembly and an adjusting piece. The bottom plate is provided at one end of the feeding conveyor and close to the centering mechanism. The main rolling assembly is fixedly installed on the upper side of the bottom plate. The support is provided at one end of the main rolling assembly close to the discharging conveyor. The secondary rolling assembly is provided on both sides of the main rolling assembly. The adjusting piece is provided on the lower side of the main rolling assembly. The detection mechanism includes a connecting plate, a linear assembly, and a vision inspection device. The connecting plate is fixedly installed on the upper side of the base plate, the linear assembly is fixedly connected to the connecting plate, and the vision inspection device is installed on the linear assembly. The centering mechanism enables automatic centering of incoming materials, achieving fully automated roll plate production under real-time detection by the inspection mechanism.

[0006] Furthermore, the centering mechanism includes a power component, a pusher plate one, a pusher plate two, and a pressing component. The bottom of the material conveyor belt near the four-roll plate bending machine is fixedly connected to the power component via a rectangular plate. The upper side of the power component is fixedly connected to pusher plate one and pusher plate two, and pressing components are installed on both pusher plate one and pusher plate two.

[0007] Furthermore, the power assembly includes a motor, a gear, a rack, and a rack. The bottom of the material conveyor belt near the four-roll plate bending machine is fixedly connected to the motor. The upper output end of the motor is fixedly connected to the gear. The outer side of the gear is meshed with racks 1 and 2. A push plate is fixedly connected to the upper side of rack 1, and a push plate is fixedly connected to the upper side of rack 2.

[0008] Metal sheets are conveyed into the working area by an incoming conveyor belt. When the sheet reaches the centering mechanism area, the control system activates the power unit. Motor 1 drives gear 1 to rotate, which in turn drives rack 1 and rack 2 meshing with it to move in opposite or opposite directions in a linear motion. This, in turn, pushes push plates 1 and 2 fixed on the racks to move synchronously, clamping or pushing the sheet from both sides, aligning its centerline with the centerline of the rollers of the subsequent plate rolling machine. Furthermore, the pressing assembly includes an electric telescopic rod, a rotating rod, and a pressure roller. The electric telescopic rod is rotatably connected to the side of the push plate 1 and push plate 2 away from the center of the incoming material conveyor belt. The other end of the electric telescopic rod 1 is rotatably connected to the rotating rod. The pressure roller is rotatably connected to one end of the electric telescopic rod 1. The other end of the electric telescopic rod 1 is rotatably connected to its corresponding push plate 1 and push plate 2 respectively.

[0009] During or after centering, the pressing assembly begins operation. As the electric telescopic rod extends, it pushes the rotating rod and the pressure roller at its end downwards, pressing into contact with the surface of the sheet material. Sheets warped during transport are locally flattened, ensuring they enter the rolling machine in a flat state. This lays the foundation for high-precision rolling and also prevents warping during the rolling process from affecting accuracy.

[0010] Furthermore, the main winding assembly includes a second motor, a gearbox, a second gear, a third gear, and a main winding roller. The second motor is fixedly connected to the upper side of the base plate. The output end of the second motor is fixedly connected to the gearbox. The output end of the gearbox is fixedly connected to the second gear. The third gear meshes with the outer side of the second gear. The main winding roller is fixedly connected to the side of the third gear away from the second motor. The main winding roller is rotatably connected to the base plate.

[0011] Furthermore, the support component includes a rotating connecting block and an electric telescopic rod II. The rotating connecting block is rotatably connected to the inner side of the base plate, and the rotating connecting block is rotatably connected to the main roller. The electric telescopic rod II is rotatably connected to the base plate, and the electric telescopic rod II is rotatably connected to the rotating connecting block.

[0012] Furthermore, the auxiliary winding assembly includes an electric telescopic rod three, a movable block, and an auxiliary winding roller. Auxiliary winding rollers are provided on both sides of the main winding roller. Movable blocks are rotatably connected to both ends of the auxiliary winding rollers. The movable blocks are rotatably connected to the base plate. The other end of the movable block is rotatably connected to the electric telescopic rod three, which is rotatably connected to the base plate.

[0013] Furthermore, the adjusting component includes an electric telescopic rod four, a bearing block, and an adjusting roller. Two sets of bearing blocks are slidably connected to the inner side of the base plate, and the electric telescopic rod four is rotatably connected to the outer side of the bearing block. The electric telescopic rod four is rotatably connected to the base plate, and an adjusting roller is rotatably connected between the two sets of bearing blocks.

[0014] The sheet metal is fed between the main roll and the adjusting roll of the four-roll plate bending machine. The height of the adjusting roll is adjusted by extending or retracting the electric telescopic rod. At this time, the auxiliary roll of the auxiliary rolling assembly is in the starting position.

[0015] When motor two starts, the power is transmitted through the gearbox, driving gear two to drive gear three, ultimately causing the main winding roller to rotate actively, providing the main torque for the sheet rolling.

[0016] The electric telescopic rod extends in three directions, and drives the auxiliary rollers on both sides to rotate through the movable block, thereby realizing the rolling and shaping of the board.

[0017] Furthermore, the linear assembly includes a third motor, a support block, a lead screw, and a moving block. The third motor is fixedly connected to the upper side of the connecting plate, and the lead screw is fixedly connected to the output end of the third motor. Two sets of support blocks are provided on the outer side of the lead screw, and the lead screw and the support blocks are rotatably connected. The moving block is threadedly connected to the outer side of the lead screw, and a sliding groove corresponding to the moving block is provided on the connecting plate.

[0018] Furthermore, the visual inspection includes an industrial camera, a bracket, and a light source. The bracket is fixedly connected to the lower side of the moving block, the industrial camera is fixedly connected to the lower side of the bracket, and a light source is fixedly connected to the lower part of the bracket and directly below the industrial camera.

[0019] During the rolling process, the inspection mechanism operates continuously. A three-motor drive screw rotates, causing a moving block to move the vision inspection component below it back and forth. An industrial camera, aided by a light source, continuously captures images of the contours of the bending sheet material. The image data is transmitted to the control system in real time, where image processing algorithms calculate the current real-time radius of curvature of the sheet material.

[0020] The control system compares the detected real-time curvature with the preset target curvature. If the real-time curvature is less than the target value, the electric telescopic rod is retracted, which in turn drives the auxiliary rollers on both sides to rotate away from the main roller, increasing the radius of curvature.

[0021] If the real-time curvature is greater than the target value, the electric telescopic rod is controlled to extend three times, thereby driving the auxiliary rollers on both sides to rotate and move closer to the main roller, reducing the radius of curvature.

[0022] This process forms a closed loop of "detection-comparison-adjustment" until a cylinder that perfectly matches the target curvature is rolled out.

[0023] Once the sheet material is rolled into a qualified cylindrical shape and the ends are joined, the electric telescopic rod retracts three times, driving the auxiliary rolling rollers on both sides to reset via the movable block. Then, the electric telescopic rod retracts two times, causing the rotating connecting block to rotate and separate from the main rolling roller. At the same time, the adjusting roller is controlled to move down, and the finished product with the qualified cylindrical shape is removed from the main rolling roller and placed on the discharge conveyor belt by an external robotic arm for transport to the next process.

[0024] Compared with the prior art, the present invention provides a fully automatic four-roll plate bending machine, which has the following advantages: 1. This invention integrates a vision inspection mechanism, using an industrial camera and light source to capture the bending contour of the sheet material in real time and calculate the real-time curvature, forming a closed-loop control system of "detection-comparison-adjustment". This solves the technical defects of existing technologies where "process parameters cannot be fed back in real time and rely on human experience". The system can automatically control the position of the three precisely adjustable auxiliary rollers of the electric telescopic rod, dynamically correcting the bending radius, thereby ensuring that the curvature of each product is highly consistent with the preset target value, fundamentally eliminating the problems of dimensional dispersion and unstable batch quality caused by manual intervention.

[0025] 2. This invention achieves automatic and precise centering of the sheet metal through the linkage of a motor and gear rack in the centering mechanism. Rolling and forming are completed through programmed coordinated actions of various electric telescopic rods and the main rolling mechanism. Finally, the finished product is output through coordinated unloading. This continuous automated process completely solves the problem of "disjointed connections between processes" in existing technologies. It integrates multiple processes that were previously scattered and reliant on manual judgment and operation into a seamless production line, not only improving production efficiency but also reducing the stringent requirements on operators' personal experience and skills, thus achieving standardization and intelligent production.

[0030] Furthermore, the centering mechanism 2 includes a power assembly 21, a pusher plate 1 22, a pusher plate 23, and a pressing assembly 24. The bottom of the material conveyor belt 1 near the four-roll plate bending machine 3 is fixedly connected to the power assembly 21 by a rectangular plate. The upper side of the power assembly 21 is fixedly connected to the pusher plate 1 22 and the pusher plate 23. The pressing assembly 24 is installed on both the pusher plate 1 22 and the pusher plate 23.

[0031] Furthermore, the power assembly 21 includes a motor 211, a gear 212, a rack 213, and a rack 214. The bottom of the material conveyor belt 1 near the four-roll plate bending machine 3 is fixedly connected to the motor 211.

[0032] Metal sheets are conveyed into the working area by the incoming conveyor belt 1. When the sheet reaches the centering mechanism 2 area, the control system activates the power unit 21. Motor 1 211 drives gear 1 212 to rotate, causing rack 1 213 and rack 2 214 meshing with it to move in opposite or opposite directions in a straight line, thereby pushing push plate 1 22 and push plate 2 23 fixed on the rack to move synchronously, clamping or pushing the sheet from both sides, aligning its center line with the center line of the roller shaft of the subsequent plate rolling machine; Furthermore, the pressing assembly 24 includes an electric telescopic rod 241, a rotating rod 242, and a pressure roller 243.

The other end of the electric telescopic rod 241 is rotatably connected to its corresponding push plate 22 and push plate 23.

[0033] During or after centering, the pressing assembly 24 begins operation. The electric telescopic rod 241 extends, pushing the rotating rod 242 and the pressure roller 243 installed at its end downwards to contact the surface of the sheet material. The sheet material, which has warped due to transportation, is locally flattened to ensure that it enters the rolling machine in a flat state, laying the foundation for high-precision rolling and preventing warping from affecting accuracy during the rolling process.

[0034] Furthermore, the main winding assembly 32 includes a second motor 321, a gearbox 322, a second gear 323, a third gear 324, and a main winding roller 325. The second motor 321 is fixedly connected to the upper side of the base plate 31. The output end of the second motor 321 is fixedly connected to the gearbox 322.

[0036] Furthermore, the auxiliary winding assembly 34 includes an electric telescopic rod 341, a movable block 342, and an auxiliary winding roller 343. The auxiliary winding roller 343 is provided on both sides of the main winding roller 325. The movable block 342 is rotatably connected to both ends of the auxiliary winding roller 343. The movable block 342 is rotatably connected to the base plate 31. The electric telescopic rod 341 is rotatably connected to the other end of the movable block 342. The electric telescopic rod 341 is rotatably connected to the base plate 31.

[0037] Furthermore, the adjusting component 35 includes an electric telescopic rod 351, a bearing block 352, and an adjusting roller 353. Two sets of bearing blocks 352 are slidably connected to the inner side of the base plate 31, and the electric telescopic rod 351 is rotatably connected to the outer side of the bearing block 352. The electric telescopic rod 351 is rotatably connected to the base plate 31, and the adjusting roller 353 is rotatably connected between the two sets of bearing blocks 352.

[0038] The sheet material is fed between the main rolling roller 325 and the adjusting roller 353 of the four-roll plate rolling machine 3. The height of the adjusting roller 353 is adjusted by extending and retracting the electric telescopic rod 351. At this time, the auxiliary rolling roller 343 of the auxiliary rolling assembly 34 is in the starting position.

[0039] When motor 2 321 starts, the power is transmitted through gearbox 322, driving gear 2 323 to drive gear 3 324, ultimately causing the main winding roller 325 to rotate actively, providing the main torque for the rolling of the sheet metal.

[0040] The electric telescopic rod 341 extends out and drives the auxiliary rollers 343 on both sides to rotate through the movable block 342, thereby realizing the rolling and forming of the board.

[0041] Furthermore, the linear assembly 42 includes a motor 421, a support block 422, a lead screw 423, and a moving block 424. The motor 421 is fixedly connected to the upper side of the connecting plate 41. The lead screw 423 is fixedly connected to the output end of the motor 421. Two sets of support blocks 422 are provided on the outer side of the lead screw 423. The lead screw 423 and the support blocks 422 are rotatably connected. The moving block 424 is threadedly connected to the outer side of the lead screw 423. The connecting plate 41 has a groove corresponding to the moving block 424.

The bracket 432 is fixedly connected to the lower side of the motion block 424, the industrial camera 431 is fixedly connected to the lower side of the bracket 432, and the light source 433 is fixedly connected to the lower part of the bracket 432 and directly below the industrial camera 431.

[0043] During the rolling process, the inspection mechanism 4 operates continuously. Motor 3 421 drives the lead screw 423 to rotate, causing the moving block 424 to move the vision inspection component 43 below it back and forth. With the assistance of light source 433, the industrial camera 431 continuously captures images of the contour of the bending sheet material. The image data is transmitted to the control system in real time, and the current real-time radius of curvature of the sheet material is calculated using image processing algorithms.

[0044] The control system compares the detected real-time curvature with the preset target curvature. If the real-time curvature is less than the target value, the control system retracts the electric telescopic rod 341, thereby driving the auxiliary rollers 343 on both sides to rotate away from the main roller 325 and increase the radius of curvature.

[0045] If the real-time curvature is greater than the target value, the electric telescopic rod 341 is extended, thereby driving the auxiliary rollers 343 on both sides to rotate and move closer to the main roller 325, reducing the radius of curvature.

[0046] This process forms a closed loop of "detection-comparison-adjustment" until a cylinder that perfectly matches the target curvature is rolled out.

[0047] Once the sheet material is rolled into a qualified cylindrical shape and the ends are joined together, the electric telescopic rod 341 retracts, driving the auxiliary rolling rollers 343 on both sides to reset via the movable block 342. Then, the electric telescopic rod 332 is controlled to retract, thereby driving the rotating connecting block 331 to rotate and separate from the main rolling roller 325. At the same time, the adjusting roller 353 is controlled to move downwards. The finished product with the qualified cylindrical shape is removed from the main rolling roller 325 by an external robotic arm and placed on the discharge conveyor belt 5 for transportation to the next process.

[0048] The specific usage and function of this embodiment are as follows: Metal sheets are conveyed into the working area by the incoming conveyor belt 1. When the sheet reaches the centering mechanism 2 area, the control system activates the power unit 21. Motor 1 211 drives gear 1 212 to rotate, causing rack 1 213 and rack 2 214 meshing with it to move in opposite or opposite directions in a linear motion, thereby pushing push plates 1 22 and 23 fixed on the rack to move synchronously, clamping or pushing the sheet from both sides, aligning its centerline with the centerline of the roller shaft of the subsequent plate rolling machine.

[0049] Preliminary flattening: During or after centering, the pressing assembly 24 begins operation. The electric telescopic rod 241 extends, pushing the rotating rod 242 and the pressure roller 243 installed at its end downwards to contact the surface of the sheet material. The sheet material, which has warped due to transportation, is locally flattened to ensure it enters the rolling machine in a flat state, laying the foundation for high-precision rolling and preventing warping during the rolling process from affecting accuracy.

[0050] After centering, the sheet material is fed between the main rolling roller 325 and the adjusting roller 353 of the four-roll plate rolling machine 3. The height of the adjusting roller 353 is adjusted by extending and retracting the electric telescopic rod 351. At this time, the auxiliary rolling roller 343 of the auxiliary rolling assembly 34 is in the starting position.

[0051] When motor 2 321 starts, the power is transmitted through gearbox 322, driving gear 2 323 to drive gear 3 324, ultimately causing the main winding roller 325 to rotate actively, providing the main torque for the rolling of the sheet metal.

[0052] The electric telescopic rod 341 extends out and drives the auxiliary rollers 343 on both sides to rotate through the movable block 342, thereby realizing the rolling and forming of the board.

[0053] Real-time curvature detection: During the rolling process, the detection mechanism 4 operates continuously. Motor 3 421 drives the lead screw 423 to rotate, causing the moving block 424 to move the vision detection component 43 below it back and forth. With the assistance of the light source 433, the industrial camera 431 continuously captures images of the contour of the bending sheet material. The image data is transmitted to the control system in real time, and the current real-time radius of curvature of the sheet material is calculated through image processing algorithms.

[0054] The control system compares the detected real-time curvature with the preset target curvature. If the real-time curvature is less than the target value, the control system retracts the electric telescopic rod 341, thereby driving the auxiliary rollers 343 on both sides to rotate away from the main roller 325 and increase the radius of curvature.

[0055] If the real-time curvature is greater than the target value, the electric telescopic rod 341 is extended, thereby driving the auxiliary rollers 343 on both sides to rotate and move closer to the main roller 325, reducing the radius of curvature.

[0056] This process forms a closed loop of "detection-comparison-adjustment" until a cylinder that perfectly matches the target curvature is rolled out.

[0057] Once the sheet material is rolled into a qualified cylindrical shape and the ends are joined together, the electric telescopic rod 341 retracts, driving the auxiliary rolling rollers 343 on both sides to reset via the movable block 342. Then, the electric telescopic rod 332 is controlled to retract, thereby driving the rotating connecting block 331 to rotate and separate from the main rolling roller 325. At the same time, the adjusting roller 353 is controlled to move downwards. The finished product with the qualified cylindrical shape is removed from the main rolling roller 325 by an external robotic arm and placed on the discharge conveyor belt 5 for transportation to the next process.
