Description

Technical Field

[0001] This utility model relates to the field of sheet metal rolling equipment, and in particular to a sheet metal rolling guide and limit device. Background Technology

[0002] Sheet metal rolling equipment is typically used to roll flat sheet metal materials into circular or curved shapes. It is widely used in the manufacture of industrial products such as metal cylinders, pipes, and tanks. Its working principle is mainly to gradually roll the sheet metal material through roller pressing to eventually form the required circular or curved shape.

[0003] Existing technologies, such as the utility model patent with publication number CN221754406U, disclose a sheet metal rolling machine. This patent uses a bracket whose top and bottom ends are slidably connected to a top plate and a support plate respectively along the lateral direction, and a pair of vertical rollers rotatably installed on the front and rear sides of the inner cavity of the bracket. The outer peripheral wall of the vertical roller has an annular groove near the top. The lifting seat is located above the middle of the top surface of the base platform. The bottom end of the limiting sleeve is rotatably fitted onto the top surface of the lifting seat. The telescopic cylinder is used to drive the bracket to slide laterally, and the vertical telescopic cylinder is used to drive the lifting seat to move up and down. The main roller is vertically located directly above the limiting sleeve, and the bottom end of the main roller is slidably fitted and matched with the limiting sleeve. A limiting ring that engages and matches the annular groove is fitted near the top of the main roller. This design avoids deviation when rolling sheet metal and improves the material feeding efficiency.

[0004] The inventors have found in the prior art that when a person moves the sheet metal body between the main roller and the auxiliary roller for rolling, the person needs to manually and accurately move the sheet metal body between the main roller and the auxiliary roller for rolling. However, since this process relies on manual control of the position of the sheet metal body throughout, it is easy for the sheet metal body to fail to maintain perpendicularity with the main roller, which leads to the problem of deviation of the sheet metal body during the rolling process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where manual control of the sheet metal body during the rolling process can easily lead to deviations in the sheet metal body. Therefore, this invention proposes a sheet metal rolling guide and limit device.

[0006] To solve the above-mentioned technical problems, this utility model provides a sheet metal rolling guide and limiting device, including: a sheet metal rolling equipment, a sheet metal body, and an adjusting structure. The sheet metal rolling equipment has a main roller, an auxiliary roller, and two side rollers installed inside. A moving device is installed on one side of the sheet metal rolling equipment, and a retaining ring is installed at one end of the moving device. The retaining ring is mounted on the main roller. A limiting structure is provided on one side of the sheet metal rolling equipment. The limiting structure includes a fixed plate, which is fixedly connected to the sheet metal rolling equipment. A positioning rod is fixedly connected to one side of the fixed plate, and a motor is fixedly connected to the side of the positioning rod away from the fixed plate. A limiting groove is formed inside the fixed plate, and a lead screw is rotatably connected to the inner wall of the limiting groove. The arc surfaces at both ends of the lead screw have opposite threads. The lead screw is rotatably connected to the fixed plate and fixedly connected to the output end of the motor. Two connecting blocks are slidably connected to the inner wall of the limiting groove. The connecting block is threadedly connected to the lead screw. A movable plate is fixedly connected to the side of the connecting block away from the sheet metal rolling equipment. A positioning block is fixedly connected to the side of the movable plate away from the connecting block. An mounting plate is fixedly connected to the upper surface of the movable plate. An auxiliary plate is slidably connected to the surface of the mounting plate. A fixing block is fixedly connected to the side of the auxiliary plate away from the sheet metal rolling equipment. An adjusting rod is rotatably connected to the inner wall of the fixing block. The arc surface of the adjusting rod is threaded. The adjusting rod is threadedly connected to the positioning block. A rotating block is fixedly connected to the upper end of the adjusting rod. A connecting rod is rotatably connected to the inner wall of the auxiliary plate. A coil spring is sleeved on the arc surface of the connecting rod. The two ends of the coil spring are fixedly connected to the auxiliary plate and the connecting rod, respectively. A rotating plate is fixedly connected to the ends of the two connecting rods that are close to each other. A limit plate is fixedly connected to the side of the rotating plate away from the connecting rod. An adjusting plate is installed on the side of the rotating plate close to the limit plate by means of an adjusting structure.

[0007] The effect achieved by the above-mentioned components is that when the operator needs to insert the sheet metal body between the main roller and the auxiliary roller for rolling, the operator can first pass the sheet metal body between the two sets of adjusting plates and limiting plates until the sheet metal body is moved between the main roller and the auxiliary roller. This can prevent the sheet metal body from shifting when the operator puts the sheet metal body between the main roller and the auxiliary roller, which would cause deviation in the rolling of the sheet metal body, thereby improving the yield of the rolled sheet metal body.

[0008] Preferably, the inner wall of the limiting groove is fixedly connected to two limiting rods, and the limiting rods are slidably connected to the connecting block.

[0009] The effect achieved by the above components is that the limiting rod can limit the connecting block and prevent the connecting block from becoming misaligned during the sliding process on the inner wall of the limiting groove.

[0010] Preferably, the arc surface of the coil spring is fitted with a bellows, and the two ends of the bellows are rotatably connected to the auxiliary plate and the connecting rod, respectively.

[0011] The effect achieved by the above components is that the bellows can protect the coil spring and reduce the risk of corrosion on the surface of the coil spring due to external factors.

[0012] Preferably, the connecting rod is a stainless steel rod.

[0013] The effect achieved by the above components is that the stainless steel rod has high strength and good wear resistance, which can prevent the connecting rod from deforming during short-term use.

[0015] The effect achieved by the above components is that when personnel need to limit sheet metal bodies of different thicknesses through the limiting structure, they can rotate the rotating column to move the position of the adjusting plate, thereby limiting sheet metal bodies of different thicknesses and improving the applicability of the limiting structure.

[0016] Preferably, the arc surface of the rotating column is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the arc surface of the rotating column.

[0017] The effect achieved by the above components is that the anti-slip groove can increase the friction between the personnel's hands and the rotating column, which can prevent the personnel from slipping during the rotation of the rotating column.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figure 1The present invention provides a sheet metal rolling guide and limiting device, comprising: a sheet metal rolling equipment 1, a sheet metal body 8, and an adjusting structure 4. The sheet metal rolling equipment 1 is internally equipped with a main roller 2, an auxiliary roller 6, and two side rollers 5. A moving device 7 is installed on one side of the sheet metal rolling equipment 1, and a retaining ring 9 is installed at one end of the moving device 7. The retaining ring 9 is installed on the main roller 2. A limiting structure 3 is provided on one side of the sheet metal rolling equipment 1, and an adjusting structure 4 is provided on the inner wall of the rotating plate 320.

[0031] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The limiting structure 3 includes a fixed plate 301, which is fixedly connected to the sheet metal rolling equipment 1. A positioning rod 305 is fixedly connected to one side of the fixed plate 301, and a motor 306 is fixedly connected to the side of the positioning rod 305 away from the fixed plate 301. A limiting groove 302 is formed inside the fixed plate 301, and a lead screw 304 is rotatably connected to the inner wall of the limiting groove 302. The arc surfaces at both ends of the lead screw 304 are provided with opposite threads. The lead screw 304 is rotatably connected to the fixed plate 301 and fixedly connected to the output end of the motor 306. Two connecting blocks 307 are slidably connected to the inner wall of the limiting groove 302. The connecting blocks 307 are threadedly connected to the lead screw 304. A moving plate 308 is fixedly connected to the side of the connecting block 307 away from the sheet metal rolling equipment 1, and a positioning block 309 is fixedly connected to the side of the moving plate 308 away from the connecting block 307. The upper surface of the moving plate 308 is fixedly connected to... A mounting plate 313 is attached, and an auxiliary plate 314 is slidably connected to the surface of the mounting plate 313. A fixing block 311 is fixedly connected to the side of the auxiliary plate 314 away from the sheet metal rolling equipment 1. An adjusting rod 310 is rotatably connected to the inner wall of the fixing block 311. The arc surface of the adjusting rod 310 is threaded and threaded to the positioning block 309. A rotating block 312 is fixedly connected to the upper end of the adjusting rod 310. A connecting rod 317 is rotatably connected to the inner wall of the auxiliary plate 314. A coil spring 318 is sleeved on the arc surface of the connecting rod 317. The two ends of the coil spring 318 are fixedly connected to the auxiliary plate 314 and the connecting rod 317, respectively. A rotating plate 320 is fixedly connected to the end of each connecting rod 317 that is close to each other. A limit plate 315 is fixedly connected to the side of the rotating plate 320 away from the connecting rod 317. An adjusting plate 316 is installed on the side of the rotating plate 320 that is close to the limit plate 315 by means of the adjusting structure 4. When personnel need to insert the sheet metal body 8 between the main roller 2 and the auxiliary roller 6 for rolling, they can first pass the sheet metal body between the two sets of adjusting plates 316 and the limiting plate 315 until the sheet metal body 8 is moved between the main roller 2 and the auxiliary roller 6. This prevents the sheet metal body 8 from shifting when it is placed between the main roller 2 and the auxiliary roller 6, which would cause deviation in the rolling process and thus improve the yield rate of the rolled sheet metal body 8. Two limiting rods 303 are fixedly connected to the inner wall of the limiting groove 302, and the limiting rods 303 are slidably connected to the connecting block 307. The limiting rods 303 can limit the connecting block 307 and prevent it from shifting during the sliding process of the connecting block 307 on the inner wall of the limiting groove 302. The arc surface of the coil spring 318 is fitted with a bellows 319, and the two ends of the bellows 319 are rotatably connected to the auxiliary plate 314 and the connecting rod 317, respectively. The bellows 319 protects the coil spring 318, reducing the risk of corrosion on its surface caused by external factors. The connecting rod 317 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the connecting rod 317 during short-term use.

[0032] In the embodiments of this utility model, please refer to Figure 4 The adjusting structure 4 includes a positioning groove 41, which is formed on the rotating plate 320. A slider 42 is slidably connected to the inner wall of the positioning groove 41, and the slider 42 is fixedly connected to the adjusting plate 316. A threaded rod 43 is rotatably connected to the inner wall of the positioning groove 41, and the threaded rod 43 is threadedly connected to the slider 42 and the rotating plate 320. A rotating column 44 is fixedly connected to the end of the threaded rod away from the fixed plate 301. This design allows personnel to limit sheet metal bodies 8 of different thicknesses by rotating the rotating column 44, thus moving the position of the adjusting plate 316 and limiting the sheet metal bodies 8 of different thicknesses. This improves the applicability of the limiting structure 3. Several anti-slip grooves 45 are evenly distributed on the arc surface of the rotating column 44. The anti-slip groove 45 increases the friction between the operator's hand and the rotating column 44, preventing slippage during rotation. The inner wall of the rotating plate 320 has several graduated grooves 46 evenly spaced. These grooves allow operators to quickly and easily observe the distance the adjustment plate 316 has moved, thus improving ease of operation.

[0033] The working principle of the sheet metal rolling guide and limiting device provided by this utility model is as follows: When the operator needs to roll the sheet metal body 8, the operator manually inserts one end of the sheet metal body 8 between the main roller 2 and the auxiliary roller 6. Then, the operator starts the sheet metal rolling equipment 1 to roll the sheet metal body 8. During the rolling process, the operator can control the sheet metal rolling equipment 1 to move the two side rollers 5. The side rollers are used to ensure the stability of the sheet metal body 8 during the rolling process. After the rolling is completed, the operator starts the moving device 7 to move the retaining ring 9 away from one end of the main roller 2. Then, the operator moves the formed sheet metal body 8 so that the formed sheet metal body 8 slides out of the arc surface of the main roller 2. Then, when the operator inserts the sheet metal body 8 into the main roller 2 and the auxiliary roller 6, the operator can proceed to the next step. When the distance between points 6 and 8 is reached, the operator can first start the motor 306. The output end of the motor 306 drives the lead screw 304 to rotate. The lead screw 304 drives the two connecting blocks 307 to move closer to each other. The connecting blocks 307 slide on the arc surface of the two limiting rods 303. The limiting rods 303 can limit the connecting blocks 307 to prevent misalignment during the sliding process of the connecting blocks 307 on the inner wall of the limiting groove 302. Then, the connecting blocks 307 drive the moving plate 308 to move closer to each other. The moving plate 308 drives the positioning block 309 and the mounting plate 313 to move closer to each other until the distance between the two rotating plates 320 is equal to the width of the sheet metal body 8. The parts are then matched, and then the operator rotates the rotating block 312. The rotating block 312 drives the adjusting rod 310 to rotate, the adjusting rod 310 drives the fixed block 311 to move upward, the fixed block 311 drives the auxiliary plate 314 to move upward, the auxiliary plate 314 slides on the surface of the mounting plate 313, the auxiliary plate 314 drives the connecting rod 317, the bellows 319 and the coil spring 318 to move upward, the connecting rod 317 drives the rotating plate 320 to move upward, the rotating plate 320 drives the limiting plate 315 to move upward, the limiting plate 315 also drives the adjusting plate 316 to move upward with the help of the adjusting structure 4, until the limiting plate 315 moves to a suitable height. At this time, the distance between the adjusting plate 316 and the limiting plate 315 is equal to the thickness of the sheet metal body 8. The sheet metal body 8 is then moved by personnel, passing between the two sets of adjusting plates 316 and the limiting plate 315 until it is positioned between the main roller 2 and the auxiliary roller 6. When the main roller 2 is started to rotate, the sheet metal body 8 rotates slightly. This rotation causes the limiting plate 315 and adjusting plate 316 to rotate. The limiting plate 315, through the adjusting structure 4, drives the rotating plate 320 to rotate. The rotating plate 320 then drives the connecting rod 317 to rotate, which in turn drives the coil spring 318 to rotate. The bellows 319 protects the coil spring 318, reducing the risk of corrosion due to external factors. After the main roller 2 and the auxiliary roller 6 press against the sheet metal body 8...At this point, motor 306 is restarted, moving the adjusting plate 316 and the limiting plate 315 away from the surface of the sheet metal body 8. The connecting rod 317 is made of stainless steel, which has high strength and good wear resistance, preventing deformation of the connecting rod 317 during short-term use.

[0034] In addition, when personnel need to limit the thickness of the sheet metal body 8 using the limiting structure 3, they can first use the rotating column 44 to drive the threaded rod 43 to rotate. The threaded rod 43 drives the slider 42 to move upward, and the slider 42 drives the adjusting plate 316 to move upward. The several anti-slip grooves 45 on the arc surface of the rotating column 44 can increase the friction between the personnel's hands and the rotating column 44, preventing the personnel from slipping during the rotation of the rotating column 44, until the distance between the adjusting plate 316 and the limiting plate 315 matches the thickness of the sheet metal body 8. The scale grooves 46 on the inner wall of the rotating plate 320 can make it easy for personnel to quickly see the distance the adjusting plate 316 has moved, thereby improving the ease of operation for personnel.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
