Description

Technical Field

[0001] This invention relates to the field of steel plate rolling and forming technology, and in particular to an integrated machine for testing and rolling corrosion-resistant steel plates and its usage method. Background Technology

[0002] In the field of steel plate rolling processing, integrated rolling forming machines are common equipment used to roll steel plates to the target thickness. Currently, most integrated machines on the market use manual feeding, that is, the operator aligns the end of the steel plate and manually pushes it into the inlet between the upper and lower pressure rollers. After the pressure rollers engage the steel plate, the equipment automatically completes the subsequent rolling and conveying.

[0003] However, the above methods have the following significant drawbacks in practical applications: manually pushing heavy steel plates is difficult, labor-intensive, and poses safety hazards. When rolling heavy steel plates with large thicknesses (e.g., 10mm or more) or large dimensions, the plates themselves can weigh tens or even hundreds of kilograms. It is extremely strenuous for operators to manually push them smoothly and accurately to the pressure roller inlet, often requiring multiple people or the use of auxiliary tools such as pry bars. During this process, operators need to exert force for extended periods and remain close to the rotating pressure roller, which can easily lead to muscle strain. There is also a significant safety risk of hands or clothing being caught in the pressure roller.

[0004] Therefore, it is necessary to improve the feeding structure of the existing integrated steel plate rolling and forming machine to solve the problem of heavy steel plates being difficult to push manually, and to achieve safe, stable and automated steel plate feeding. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated machine for testing and rolling of corrosion-resistant steel plates and its usage method. The L-shaped plate is driven by an electric telescopic rod, and after the steel plate is firmly clamped by the steel plate clamping mechanism, the heavy steel plate can be automatically and smoothly pushed between the upper and lower pressure rollers. With the cooperation of a laser rangefinder and an auxiliary block, it is possible to accurately determine whether the end of the steel plate has reached the predetermined position between the upper and lower pressure rollers. The sensor moving mechanism can help the electric telescopic rod to push steel plates of different lengths.

[0006] To achieve the above objectives, the present invention provides an integrated machine for testing and rolling corrosion-resistant steel plates, comprising a support, a steel plate rolling and forming device, a steel plate conveying mechanism, a steel plate clamping mechanism, a sensor moving mechanism, an electric telescopic rod, and an L-shaped plate. The fixed end of the electric telescopic rod is fixedly connected to the upright plate of the support, and the movable end of the electric telescopic rod is fixedly connected to the side wall of the L-shaped plate. The support is also provided with a steel plate conveying mechanism and a steel plate rolling and forming device. A steel plate clamping mechanism is provided on the inner side of one wall of the L-shaped plate, and a sensor moving mechanism is provided on the inner side of the other wall of the L-shaped plate.

[0007] Preferably, the steel plate rolling forming device includes an upper pressure roller and a lower pressure roller. A drive shaft is fixedly connected to the middle of the upper pressure roller. The drive shaft is driven by a drive motor and rotated on the frame. The lower pressure roller is also driven by a drive motor and rotated on the frame.

[0008] Preferably, the steel plate conveying mechanism includes multiple rollers and a connecting frame. The multiple rollers are arranged horizontally at intervals, and a rotating shaft is fixedly connected to the middle of the roller. The rotating shaft is rotatably connected to the connecting frame through a bearing. The top of the roller and the top of the lower pressure roller are located on the same plane.

[0009] Preferably, the steel plate clamping mechanism includes a fixed plate, a bidirectional screw, a clamping plate, a slider, a guide groove, and a motor. Two fixed plates are fixedly connected to the inner side of the wall opposite to the upper pressure roller of the L-shaped plate. A bidirectional screw is rotatably connected between the fixed plates. The bidirectional screw passes through the two clamping plates and is threadedly connected to the clamping plates. The two clamping plates are located on different threaded sections of the bidirectional screw. A slider is provided on one side wall of the clamping plate. A guide groove is also horizontally opened on the inner side of the wall opposite to the upper pressure roller of the L-shaped plate. One end of the slider is slidably connected in the guide groove.

[0010] Preferably, a laser rangefinder is fixedly connected to the other side wall of each of the two clamping plates. The laser rangefinders are arranged opposite each other and their probes face the side wall of the steel plate.

[0011] Preferably, the sensor moving mechanism includes a groove, a screw rod, a slider, a guide groove, and a motor. A groove is horizontally formed on the inner side of a wall parallel to the L-shaped plate and the electric telescopic rod. The two ends of the groove are rotatably connected to the screw rod. One end of the screw rod is connected to the output shaft of the motor, and the motor is fixedly connected to the end of the L-shaped plate. The screw rod passes through the slider and is threadedly connected to the slider. A guide groove is formed on the inner wall of the groove. The slider moves along the guide groove, and the direction of movement of the slider is the same as the direction of movement of the steel plate.

[0012] Preferably, a photoelectric sensor is fixedly connected to the front end of the second slider. The photoelectric sensor is disposed opposite to the side wall of the steel plate, and the probe of the photoelectric sensor faces the side wall of the steel plate.

[0013] Preferably, a laser rangefinder II is also fixedly connected to the middle wall of the second slider, and the end face of the probe of the second laser rangefinder II is flush with the axis of the probe of the photoelectric sensor.

[0014] Preferably, an auxiliary block is fixedly connected to the side wall of the frame of the steel plate rolling forming device. The auxiliary block is located to the left of the axis of the drive shaft of the upper pressure roller, and the probe of the laser rangefinder II faces the auxiliary block. The motor 1, motor 2, photoelectric sensor, laser rangefinder 1, laser rangefinder 2, and electric telescopic rod are all electrically connected to the controller, which is mounted on the upright plate of the support.

[0015] A method for using an integrated testing and rolling forming machine for corrosion-resistant steel plates includes the following steps: Step 1: Place the steel plate on the steel plate conveying mechanism, with the inner wall of the L-shaped plate parallel to the upper pressure roller in contact with one end of the steel plate; Step 2: The controller controls the operation of the steel plate clamping mechanism. Motor 1 drives the forward and reverse screws to rotate, which in turn drives the two clamping plates to move towards each other. When both laser rangefinders measure a value of zero, it means that the clamping plates can be firmly clamped on both sides of the steel plate. Step 3: The controller controls the operation of the sensor moving mechanism. Motor 2 drives screw 1 to rotate, and screw 1 drives slider 2 to move towards the steel plate rolling forming device. The signal output by the photoelectric sensor is continuously blocked by the steel plate. When the signal output by the photoelectric sensor is no longer blocked by the steel plate, the information is transmitted to the controller. The controller controls motor 2 to stop rotating, indicating that the photoelectric sensor and laser rangefinder 2 have moved to the other end of the steel plate. Step 4: The controller controls the extension of the movable end of the electric telescopic rod, causing the steel plate to move towards the steel plate rolling and forming device and move into the gap between the upper and lower pressure rollers. When the laser rangefinder detects a value of zero, it means that one end of the steel plate has moved between the upper and lower pressure rollers. At this time, the electric telescopic rod no longer needs to push the steel plate to move. Step 5: The motor rotates in the opposite direction, thus removing the steel plate from the clamp. The steel plate is then rolled under the action of the upper and lower pressure rollers. The controller resets the sensor moving mechanism, the electric telescopic rod, and the steel plate clamping mechanism, ready for the next steel plate to be processed.

[0016] The advantages and positive effects of the corrosion-resistant steel plate inspection, rolling and forming integrated machine described in this invention are: 1. The L-shaped plate is driven by an electric telescopic rod. After the steel plate is firmly clamped by the steel plate clamping mechanism, the heavy steel plate can be automatically and smoothly pushed between the upper and lower pressure rollers without the need for manual pushing. This significantly reduces the labor intensity of operators and is especially suitable for processing steel plates with large thickness and weight.

[0017] 2. By using a laser rangefinder and an auxiliary block, it is possible to accurately determine whether the end of the steel plate has reached the predetermined position between the upper and lower pressure rollers, avoiding over- or under-push. At the same time, operators do not need to approach the rotating pressure rollers, effectively preventing accidents such as hands or clothing being caught in the rollers.

[0018] 3. The sensor moving mechanism drives the photoelectric sensor to move along the side wall of the steel plate. When the photoelectric sensor signal changes from being blocked to being unblocked, it automatically stops moving, thereby accurately identifying the end position of the steel plate, which helps the electric telescopic rod to push steel plates of different lengths.

[0030] Laser rangefinder 305 is fixedly connected to the other side wall of both clamping plates 303. The laser rangefinder 305 is set opposite to each other and the probes of the laser rangefinder 305 are facing the side wall of the steel plate 10.

[0031] The sensor moving mechanism 4 includes a groove 401, a first screw 402, a second slider 403, a second guide groove 404, and a second motor 405. A groove 401 is horizontally formed on the inner side of a wall parallel to the L-shaped plate 12 and the electric telescopic rod 11. The first screw 402 is rotatably connected to both ends of the groove 401. One end of the first screw 402 is connected to the output shaft of the second motor 405.

A second guide groove 404 is formed on the inner wall of the groove 401. The second slider 403 moves along the second guide groove 404 in the same direction as the movement of the steel plate 10.

[0032] A photoelectric sensor 7 is fixedly connected to the front end of slider 2 403. The photoelectric sensor 7 is set opposite to the side wall of steel plate 10, and the probe of the photoelectric sensor 7 faces the side wall of steel plate 10.

[0033] A laser rangefinder 28 is also fixedly connected to the middle wall of slider 2 403. The end face of the probe of laser rangefinder 2 8 is flush with the axis of the probe of photoelectric sensor 7.

[0034] An auxiliary block 9 is fixedly connected to the side wall of the frame of the steel plate rolling forming device 2. The auxiliary block 9 is located to the left of the axis of the drive shaft 203 of the upper pressure roller 201, and the probe of the laser rangefinder 28 faces the auxiliary block 9.

[0035] Specifically, a clearance space is provided between the wall parallel to the L-shaped plate 12 and the electric telescopic rod 11 and the auxiliary block 9 to prevent the wall from colliding with the auxiliary block 9.

[0036] Motor 1 (307), Motor 2 (405), photoelectric sensor 7, laser rangefinder 1 (305), laser rangefinder 2 (8), and electric telescopic rod 11 are all electrically connected to controller 6, which is mounted on the upright plate of support 1.

[0037] The present invention discloses a method for using an integrated testing, rolling, and forming machine for corrosion-resistant steel plates, comprising the following steps: Step 1: Place the steel plate 10 on the steel plate conveying mechanism 5, and make the inner wall of the L-shaped plate 12 parallel to the upper pressure roller 201 contact one end of the steel plate 10.

[0038] Step 2: The controller 6 controls the operation of the steel plate clamping mechanism 3.

When both laser rangefinders 305 measure zero, it means that the clamping plates 303 can be firmly clamped on both sides of the steel plate 10.

[0039] Step 3: Controller 6 controls the operation of sensor moving mechanism 4. Motor 2 405 drives screw 1 402 to rotate. Screw 1 402 drives slider 2 403 to move closer to steel plate rolling forming device 2. The signal output by photoelectric sensor 7 is continuously blocked by steel plate 10. When the signal output by photoelectric sensor 7 is no longer blocked by steel plate 10, the information is transmitted to controller. Controller controls motor 2 405 to stop rotating, indicating that photoelectric sensor 7 and laser rangefinder 2 8 have moved to the other end of steel plate.

[0040] Step 4: Controller 6 controls the movable end of the electric telescopic rod 11 to extend, causing the steel plate to move towards the steel plate rolling forming device 2 and move into the gap between the upper pressure roller 201 and the lower pressure roller 202. When the laser rangefinder 28 detects a value of zero, it means that one end of the steel plate 10 has moved between the upper pressure roller 201 and the lower pressure roller 202. At this time, the electric telescopic rod 11 no longer needs to push the steel plate 10 to move.

[0041] Step 5: The motor 307 rotates in the reverse direction, so that the steel plate 10 is no longer clamped. The steel plate 10 is rolled under the action of the upper pressure roller 201 and the lower pressure roller 202. The controller 6 resets the sensor moving mechanism 4, the electric telescopic rod 11 and the steel plate clamping mechanism 3, waiting for the next steel plate 10 to be processed.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
