Technical Field
[0001] This invention relates to the field of plate rolling machine technology, specifically to a roll seam adjustment and positioning structure for a plate rolling machine. Background Technology
[0002] A plate rolling machine is a device that uses work rollers to bend and shape sheet metal. It can form parts of different shapes such as cylindrical and conical parts, and is a very important type of processing equipment. The working principle of a plate rolling machine is to use external forces such as hydraulic pressure and mechanical force to move the work rollers, thereby bending or rolling the sheet metal into shape. Depending on the rotation and position changes of the work rollers of different shapes, parts such as elliptical, arc-shaped, and cylindrical parts can be processed.
[0003] The shortcomings of existing technology:
[0004] After the plate rolling machine presses the cylindrical product, the roll seam is usually located at the bottom. In the subsequent welding process, the roll seam needs to be aligned upwards with the bottom of the welded structure, and then the roll seam is closed by a clamping device for welding. Therefore, the rolled material needs to be removed from the plate rolling machine first, the angle of the roll seam needs to be adjusted, and then it needs to be sent to the automatic welding line for welding. It is not possible to directly send the rolled material to the automatic welding line for welding, which not only reduces the efficiency of rolling material to welding, but also increases the wage burden of workers.

[0031] As a further improvement of the present invention, the support mechanism is symmetrically arranged with the upper roller of the rolling device as the center, and the upper end of the support mechanism and the upper end of the lower roller are on the same horizontal plane.
[0032] As a further improvement of the present invention, the adjustment and positioning method of the roll seam adjustment and positioning structure includes the following steps:
[0033] S1. The metal sheet is rolled into a roll of the corresponding specifications by the rolling device: the lifting hydraulic cylinder is started, the lifting hydraulic cylinder drives the lifting plate to move downward, the distance between the lower end of the support beam and the upper roller of the rolling device is set according to the diameter of the roll, the lifting hydraulic cylinder is closed, and then the rolling device is started to roll the roll. After the roll is rolled into shape, it is wrapped around the support beam and the upper roller of the rolling device.
[0034] S2. Rotate the roll of material from the bottom to the top, following these steps:
[0035] a. First, the cylinder is started, and the cylinder pushes the limit frame to move downward. During this process, the sector gear disk is rotated by the action of the gear rack, and then the connecting rod is pulled to move. The connecting rod pulls the movable plate to move horizontally. The positioning post is affected by the guide post and the guide groove. The tilt angle of the positioning post becomes smaller. The ball at its lower end contacts the plate and compresses the positioning post to retract a certain distance. Then the cylinder stops moving.
[0036] b. Then start the upper roller of the rolling device. The upper roller rotates and drives the roll material to rotate through friction. After the roll seam of the roll material rotates to the upper end, the lower end of the positioning post extends and inserts into the roll seam, and the edge of the roll material contacts the positioning wheel. The pressure sensor detects the pressure, that is, the contact part reaches the positioning line. The positioning wheel rotates to block the contact part from continuing to rotate, and the edge of the roll material is calibrated to ensure that the edge of the roll material is in a straight line. When all the pressure sensors detect the pressure, that is, the edge of the roll material is in a straight line, the adjustment and positioning are completed, and the driving hydraulic cylinder is activated.
[0037] c. Control the lower roller of the coiling device and the lifting hydraulic cylinder to move downwards synchronously a certain distance, so that the coil material no longer contacts the lower end of the upper roller of the coiling device, and then stop the movement. Then start the driving hydraulic cylinder and the lifting hydraulic cylinder to move upwards synchronously a certain distance. The driving hydraulic cylinder pushes the support frame to move upwards, and the roller lifts the coil material, ensuring that there is a certain gap between the lower inner surface of the coil material and the upper roller of the coiling device. The cylinder continues to move downwards until the limiting wheel contacts both sides of the upper end face of the coil material. At this time, the lower end of the coil material is supported by the roller, and the two sides of the roll seam are limited by the limiting roller and the limiting wheel, and the positioning post is inserted into the roll seam.
[0038] S3. Transport the adjusted and positioned roll material to the automatic welding line: Start the drive motor, which drives the conveying slider to move inside the conveying groove of the conveying guide rail. The pusher frame moves accordingly, and the pusher block pushes the roll material onto the automatic welding line.
[0039] Compared with the prior art, the beneficial effects of the present invention are:
[0040] 1. In this invention, a support mechanism is provided, which includes a fixed frame, a driving hydraulic cylinder, a support frame and several rollers. Through the action of the support mechanism, and in conjunction with the upper roller drive of the plate rolling machine, the roll seam can be adjusted from bottom to top without manual adjustment.
[0041] 2. In this invention, a limiting mechanism is provided. The limiting mechanism includes a stand, a support beam, a fixed beam, several cylinders, a limiting frame, and a seam positioning component. The seam positioning component includes a sector gear disk, a gear rack, a movable plate, and a positioning column. It can accurately detect whether the seam has been adjusted to the specified position and can effectively determine whether the roll material has shifted during the adjustment process, causing the seam edges to be out of straight line. When the seam edges shift, it can automatically calibrate until the seam edges are in straight line, ensuring that the seam can be accurately adjusted, thereby improving the accuracy of the seam during subsequent welding and improving the welding quality.
[0042] 3. In this invention, a conveying mechanism is provided, which includes a conveying guide rail, a conveying slider and a pushing frame. Through the action of the conveying mechanism, and with the support and limitation of rollers, limiting rollers and limiting wheels, the positioned roll material can be directly pushed out and conveyed to the automatic welding line, avoiding the roll material from deviating during the conveying process.

[0057] Example 1
[0058] Please see Figure 1-10 The present invention provides a technical solution: a roll seam adjustment and positioning structure for a plate rolling machine, comprising a plate rolling machine 1, a support mechanism 2 for supporting and assisting the rotation of the roll material is installed on both sides of the roll shaft on the plate rolling machine 1, and a limiting mechanism 3 for limiting the roll material after the roll seam adjustment and positioning is completed is installed on the upper end of the plate rolling machine 1. The plate rolling machine 1 includes a frame 101, a control box 102 for controlling the operation of the control device and a plate rolling device 103. The control box 102 and the plate rolling device 103 are both installed on the upper end of the frame 101, and the two ends of the fixing frame 21 and the upright frame 31 are all fixed to the frame 101 by bolts.
[0059] The support mechanism 2 includes a fixed frame 21, a driving hydraulic cylinder 22, a support frame 23, and several rollers 24. The two ends of the fixed frame 21 are fixed to the plate rolling machine 1. The fixed end of the driving hydraulic cylinder 22 is fixed to the fixed frame 21 by bolts. The support frame 23 is formed by welding two clamping plates in parallel. The support frame 23 is fixed to the telescopic end of the driving hydraulic cylinder 22 by bolts. The rollers 24 are rotatably installed between the two clamping plates of the support frame 23 via a rotating shaft. When in use, the extension or retraction of the driving hydraulic cylinder 22 causes the support frame 23 to rise or fall along the inclined direction of the driving hydraulic cylinder 22. The rollers 24 support both sides of the lower end of the roll material, which can stably and conveniently adjust the height of the roll material, facilitating the rotation and conveying of the roll material.
[0060] The limiting mechanism 3 includes a stand 31, a support beam 33, a fixed beam 35, several cylinders 37, a limiting frame 38, and a seam positioning assembly 310. The stand 31 is fixed to the upper end of one side of the plate rolling machine 1. A lifting assembly 32 is installed on the stand 31. One end of the support beam 33 is fixed to the lifting end of the lifting assembly 32. Several limiting rollers 34 are rotatably installed on both sides of the upper end of the support beam 33. One end of the fixed beam 35 is fixed to the lifting end of the lifting assembly 32 and is located above the support beam 33. The lower end face of the fixed beam 35... Several columns 36 are bolted to both sides, and the lower ends of the columns 36 are bolted to the fixed beam 35. A cylinder 37 is fixed to the lifting end of the lifting assembly 32 and the end of the fixed beam 35 away from the lifting assembly 32. A limiting frame 38 is bolted to the lower end of the cylinder 37 and is slidably connected to the columns 36. Several limiting wheels 39 are rotatably mounted on the lower ends of both sides of the limiting frame 38. A seam positioning assembly 310 is mounted on the limiting frame 38. The lifting assembly 32 includes a lifting hydraulic system. Hydraulic cylinder 321 and lifting plate 322 are used. The lower end of the lifting hydraulic cylinder 321 is fixed to the upright 31 by bolts. The telescopic end of the lifting hydraulic cylinder 321 is connected to the lifting plate 322. The lifting plate 322 is slidably connected to the upright 31. The support beam 33, fixed beam 35, and cylinder 37 are all fixed to the lifting plate 322 by bolts. When the sheet metal is rolled, the lifting hydraulic cylinder 321 drives the lifting plate 322 to move downward. When the lower end of the support beam 33 is 1-1.5cm away from the upper roller of the rolling device 103, the roll... After the material is rolled into shape, it is wrapped around the support beam 33 and the upper roller of the rolling device 103. When the rolled material is positioned, the lower roller of the rolling device 103 and the lifting hydraulic cylinder 321 move downwards synchronously to a certain distance, so that the rolled material no longer contacts the lower end of the upper roller of the rolling device 103. Then the movement stops, and the cylinder 37 continues to move downwards until the limiting wheel 39 contacts both sides of the upper end face of the rolled material. At this time, the lower end of the rolled material is supported by the roller 24, and the two sides of the roll seam are limited by the limiting roller 34 and the limiting wheel 39.
[0061] The seam positioning assembly 310 includes a sector gear disk 3101, a gear rack 3103, a movable plate 3104, and a positioning post 3105. The sector gear disk 3101 is rotatably mounted on both sides of the limiting frame 38 via a rotating shaft. One side of the sector gear disk 3101 is connected to a connecting rod 3102 via a rotating shaft. The gear rack 3103 is fixed to two uprights 36 near the lifting assembly 32 and meshes with the sector gear disk 3101. The movable plate 3104 is fixed to the limiting frame 38. The limiting groove is slidably connected, one end of the connecting rod 3102 is rotatably connected to the movable plate 3104, the positioning post 3105 is rotatably installed at the lower end of the movable plate 3104, the positioning post 3105 includes a gas spring, a guide post 5 is rotatably installed on the positioning post 3105, the limiting frame 38 is provided with a guide groove 6 for limiting the movement of the guide post 5, the lower end of the positioning post 3105 is embedded with a ball 7 for reducing friction, and a positioning wheel 3106 is rotatably installed at the lower end of the positioning post 3105. A pressure sensor 3107 is installed in a groove. When adjusting the position of the positioning seam, the cylinder 37 pushes the limit frame 38 downward. During this process, the sector gear disk 3101 rotates under the action of the gear rack 3103, and then pulls the connecting rod 3102 to move. The connecting rod 3102 pulls the movable plate 3104 to move horizontally. The positioning post 3105 is acted upon by the guide post 5 and the guide groove 6. The tilt angle of the positioning post 3105 decreases, and the ball bearing 7 at its lower end contacts the plate and compresses the positioning post 310. 5. After shrinking a certain distance, cylinder 37 stops. After the roll seam of the material rotates to the upper end, the positioning post 3105 extends and inserts its lower end into the roll seam, and the edge of the material contacts the positioning wheel 3106. Pressure sensor 3107 detects the pressure, that is, the contact part reaches the positioning line. The positioning wheel 3106 rotates to stop the contact part from continuing to rotate, and the edge of the material is calibrated to ensure that the edge of the material is in a straight line. When all pressure sensors 3107 detect the pressure, that is, the edge of the material is in a straight line, the adjustment and positioning are completed.
[0062] A conveying mechanism 4 for unloading material after the roll seam positioning is completed is installed on the upper end of the fixed beam 35. The conveying mechanism 4 includes a conveying guide rail 41, a conveying slider 42, and a pusher frame 44. The conveying guide rail 41 is fixedly installed on the upper end of the fixed beam 35 by bolts. The two ends of the conveying guide rail 41 are respectively bolted to the lifting plate 322 and the fixed beam 35. The conveying slider 42 is slidably connected to the conveying groove of the conveying guide rail 41. A drive motor 43 for driving the conveying slider 42 to slide in the conveying groove is installed on the conveying slider 42. The pusher frame 44 is welded to the conveying slider 42. Pushing blocks 45 are welded to both sides of the lower end of the pusher frame 44. When the roll material is conveyed to the automatic welding line, the drive motor 43 is started. The drive motor 43 drives the conveying slider 42 to move inside the conveying groove of the conveying guide rail 41. The pusher frame 44 moves accordingly and pushes the roll material to the automatic welding line through the pusher blocks 45.
[0063] The rotation of roller 24, limit roller 34 and limit wheel 39 is in the same direction as the conveying direction of the roll material, which can reduce the friction of roller 24, limit roller 34 and limit wheel 39 on the conveying direction of the roll material.
[0064] The support mechanism 2 is symmetrically distributed around the upper roller of the rolling device 103. The upper end of the support mechanism 2 is on the same horizontal plane as the upper end of the lower roller, which ensures that the roll material can be effectively supported.
[0065] Example 2
[0066] Please see Figure 1-10 The present invention also provides a technical solution: an adjustment and positioning method for a roll seam adjustment and positioning structure, comprising the following steps:
[0067] S1. The metal sheet is rolled into a roll of the corresponding specification by the rolling device 103: the lifting hydraulic cylinder 321 is started, the lifting hydraulic cylinder 321 drives the lifting plate 322 to move downward, the distance between the lower end of the support beam 33 and the upper roller of the rolling device 103 is set according to the diameter of the roll, the lifting hydraulic cylinder 321 is closed, and then the rolling device 103 is started to roll the roll. After the roll is rolled into shape, it is wrapped around the support beam 33 and the upper roller of the rolling device 103.
[0068] S2. Rotate the roll of material from the bottom to the top, following these steps:
[0069] a. First, start cylinder 37. Cylinder 37 pushes limit frame 38 to move downward. During this process, sector gear disk 3101 is rotated by gear rack 3103. Then, pull connecting rod 3102 to move. Connecting rod 3102 pulls movable plate 3104 to move horizontally. Positioning column 3105 is affected by guide column 5 and guide groove 6. The tilt angle of positioning column 3105 becomes smaller. The ball 7 at its lower end contacts the plate and compresses positioning column 3105. After it retracts a certain distance, cylinder 37 stops moving.
[0070] b. Then start the upper roller of the rolling device 103. The upper roller rotates and drives the roll material to rotate through friction. After the roll seam of the roll material rotates to the upper end, the lower end of the positioning post 3105 extends and inserts into the roll seam, and the edge of the roll material contacts the positioning wheel 3106. The pressure sensor 3107 detects the pressure, that is, the contact part reaches the positioning line.
[0071] When all pressure sensors 3107 detect pressure synchronously, that is, when the seam edges are on the same straight line, the adjustment and positioning are completed, and the upper roller of the rolling device 103 can be turned off.
[0072] If only one or a few pressure sensors 3107 detect pressure, that is, the roll seam edges are not on the same straight line, the upper roller of the roll plate device 103 continues to drive the roll material to rotate, and the positioning wheel 3106 rotates to block the contact part from continuing to rotate, thus calibrating the roll material edge. When all pressure sensors 3107 detect pressure, that is, the roll material edge is on a straight line, the adjustment and positioning are completed, and the next operation is carried out.
[0073] c. Control the lower roller of the coiling device 103 and the lifting hydraulic cylinder 321 to move downwards synchronously a certain distance, so that the coil material no longer contacts the lower end of the upper roller of the coiling device 103. Then stop the movement, and then start the drive hydraulic cylinder 22 and the lifting hydraulic cylinder 321 to move upwards synchronously a certain distance. Drive the hydraulic cylinder 22 to push the support frame 23 to move upwards, and the roller 24 lifts the coil material, ensuring that there is a certain gap between the lower inner surface of the coil material and the upper roller of the coiling device 103. The cylinder 37 continues to move downwards until the limit wheel 39 contacts both sides of the upper end face of the coil material. At this time, the lower end of the coil material is supported by the roller 24, and the two sides of the roll seam are limited by the limit roller 34 and the limit wheel 39, and the positioning post 3105 is inserted into the roll seam.
[0074] S3. Transport the adjusted and positioned roll material to the automatic welding line: Start the drive motor 43. The drive motor 43 drives the conveyor slider 42 to move inside the conveyor groove of the conveyor guide rail 41. The pusher frame 44 moves accordingly and pushes the roll material to the automatic welding line through the pusher block 45.
[0075] This invention enables bottom-up adjustment of the roll seam without manual intervention. It can accurately detect whether the seam has been adjusted to the designated position and effectively determine whether the roll has shifted during the adjustment process, causing the seam edges to be out of straight. If the seam edges shift, it can automatically calibrate until they are aligned, ensuring precise adjustment of the roll seam. This improves the accuracy of the roll seam during subsequent welding and enhances welding quality. The positioned roll seam can be directly pushed out and conveyed to the automatic welding line, avoiding roll seam shifting during the conveying process.

8. The roll seam adjustment and positioning structure for a plate rolling machine according to claim 7, characterized in that: The adjustment and positioning method of the roll seam adjustment and positioning structure includes the following steps: S1. The metal sheet is rolled into a roll of the corresponding specifications by the rolling device: the lifting hydraulic cylinder is started, the lifting hydraulic cylinder drives the lifting plate to move downward, the distance between the lower end of the support beam and the upper roller of the rolling device is set according to the diameter of the roll, the lifting hydraulic cylinder is closed, and then the rolling device is started to roll the roll. After the roll is rolled into shape, it is wrapped around the support beam and the upper roller of the rolling device. S2. Rotate the roll of material from the bottom to the top, following these steps: a. First, the cylinder is started, and the cylinder pushes the limit frame to move downward. During this process, the sector gear disk is rotated by the action of the gear rack, and then the connecting rod is pulled to move. The connecting rod pulls the movable plate to move horizontally. The positioning post is affected by the guide post and the guide groove. The tilt angle of the positioning post becomes smaller. The ball at its lower end contacts the plate and compresses the positioning post to retract a certain distance. Then the cylinder stops moving. b. Then start the upper roller of the rolling device. The upper roller rotates and drives the roll material to rotate through friction. After the roll seam of the roll material rotates to the upper end, the lower end of the positioning post extends and inserts into the roll seam, and the edge of the roll material contacts the positioning wheel. The pressure sensor detects the pressure. When the contact part between the edge of the roll material and the positioning wheel reaches the positioning line, the positioning wheel rotates to block the contact part from continuing to rotate, and the edge of the roll material is calibrated to ensure that the edge of the roll material is in a straight line. When all the pressure sensors detect the pressure, that is, when the edge of the roll material is in a straight line, the adjustment and positioning are completed. c. Control the lower roller of the coiling device and the lifting hydraulic cylinder to move downwards synchronously a certain distance, so that the coil material no longer contacts the lower end of the upper roller of the coiling device, and then stop the movement. Then start the driving hydraulic cylinder and the lifting hydraulic cylinder to move upwards synchronously a certain distance. The driving hydraulic cylinder pushes the support frame to move upwards, and the roller lifts the coil material, ensuring that there is a certain gap between the lower inner surface of the coil material and the upper roller of the coiling device. The cylinder continues to move downwards until the limiting wheel contacts both sides of the upper end face of the coil material. At this time, the lower end of the coil material is supported by the roller, and the two sides of the roll seam are limited by the limiting roller and the limiting wheel, and the positioning post is inserted into the roll seam. S3. Transport the adjusted and positioned roll material to the automatic welding line: Start the drive motor, which drives the conveying slider to move inside the conveying groove of the conveying guide rail. The pusher frame moves accordingly, and the pusher block pushes the roll material onto the automatic welding line.
