Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, and in particular to a plate rolling machine with adaptive clamping function. Background Technology

[0002] The plate rolling process is a continuous three-point bending process of plate. According to different rolling temperatures, it can be divided into cold rolling, hot rolling and warm rolling. It is mainly used to bend metal plates of a certain thickness into cylindrical, arc, rectangular and other curvature or variable curvature mechanical equipment. It is one of the essential mechanical equipment in industries such as metallurgy, building materials, shipbuilding, and boilers.

[0003] In existing technology, plate rolling machines cannot limit the plates to be processed during operation, which causes the plates to move left and right during processing, resulting in wrinkles on the surface of the processed plates and affecting sales.

[0004] An existing patent (publication number: CN217191840U) discloses a plate rolling machine with a limiting device. When this device is used, the motor is started before the plate rolling machine starts working. The motor starts and drives the rotating shaft to rotate. The rotating shaft drives the first gear to rotate. The first gear drives the second gear to rotate. The second gear drives the threaded drum to rotate. The rotating drum drives the threaded rod to move. The rotating shaft rotates forward and reverses and drives the threaded rod to move outward. The movement of the threaded rod drives the limiting clamps to move. The operator controls the distance between the limiting clamps by controlling the forward and reverse rotation and opening and closing of the motor, so that the limiting clamps fit with the left and right sides of the rolled material to limit the material. After the material is limited, the plate rolling machine can be started to work.

[0005] To address the aforementioned issues, while existing patents offer solutions that can limit and clamp the sheet metal using components such as motors, a problem exists in actual use: the clamping force cannot be precisely controlled. This can lead to over-clamping and deformation of the sheet metal, especially for thinner metal sheets, which may even cause arching, thus affecting the quality of the rolled sheet. Summary of the Invention

[0006] The purpose of this utility model is to provide a plate rolling machine with adaptive clamping function, which can solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a plate rolling machine with adaptive clamping function, comprising a plate rolling machine body, a connecting plate fixedly installed at the front end of the plate rolling machine body, and a clamping mechanism provided between the two connecting plates;

[0008] The clamping mechanism includes a rotating block rotatably connected between two connecting plates, with rotating shafts fixedly installed at both ends of the rotating block. A through groove is formed inside the rotating block, and a sliding plate is slidably connected inside the through groove. A sliding groove is formed at the bottom of the through groove, and a slider is slidably connected inside the sliding groove. A bidirectional threaded rod extends through the slider, and a motor is fixedly installed at one end of the bidirectional threaded rod. A first damping spring is embedded in the inner wall of the sliding plate, and a clamping plate is fixedly installed at one end of the first damping spring extending out of the sliding plate. A limit groove is formed on one side of the first damping spring on the outer wall of the sliding plate, and a sensor is embedded inside the limit groove.

[0009] Preferably, the rotating block forms a rotating structure with the connecting plate via a rotating shaft, and the rotating block forms a sliding structure with the sliding plate via a through groove.

[0010] Preferably, the bidirectional threaded rod is threadedly connected to the slider, and a sliding structure is formed between the slider and the sliding groove.

[0011] Preferably, the top of the sliding plate is provided with a mounting groove, and the inside of the mounting groove is provided with an abutment mechanism.

[0012] Preferably, the abutment mechanism includes a rotating plate, which is rotatably connected inside the mounting groove, and a support rod extends through one end of the rotating plate that extends out of the mounting groove. An abutment plate is sleeved on one side of the rotating plate outside the support rod.

[0013] Preferably, the abutment mechanism further includes a fixed block, which is fixedly installed on the top of the rotating block, and a through rod extends through the inside of the fixed block. A second damping spring is fixedly installed at one end of the through rod inside the fixed block, and a connecting frame is fixedly installed at the bottom end of the through rod. An abutment roller is rotatably connected between the two axes at the bottom end of the connecting frame, and a rubber layer is sleeved on the outer wall of the abutment roller.

[0014] Preferably, the contact plate forms a rotating structure with the rotating plate via a support rod, and the support rod and the through rod are perpendicular to each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the cooperation of rotating block, rotating shaft, through groove, sliding plate, sliding groove, slider, bidirectional threaded rod, motor, first damping spring, clamping plate, limit groove and sensor, it can limit the movement of metal plate during processing to prevent loosening, and prevent over-clamping during the clamping process, which could cause the metal plate to arch or even deform, thus affecting the quality of the metal plate. At the same time, it can also prevent over-clamping from affecting the smoothness of conveying.

[0017] 2. Through the cooperation of the mounting groove, rotating plate, support rod, abutment plate, fixing block, second damping spring, through rod, connecting frame, abutment roller and rubber layer, the metal plate can be limited by the clamping mechanism while being pressed down from above. This avoids the situation where the metal plate is loosened and detached due to the tensile force when the clamping mechanism is not over-clamped, which would cause the metal plate to shake and affect the processing.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution:

[0029] Please see Figures 1 to 4 A plate rolling machine with adaptive clamping function includes a plate rolling machine body 1. A connecting plate 2 is fixedly installed at the front end of the plate rolling machine body 1, and a clamping mechanism 3 is provided between the two connecting plates 2. The clamping mechanism 3 includes a rotating block 301, which is rotatably connected between the two connecting plates 2. A rotating shaft 302 is fixedly installed at both ends of the rotating block 301. A through groove 303 is opened inside the rotating block 301. A sliding plate 304 is slidably connected inside the through groove 303. A sliding groove 305 is opened at the bottom end of the through groove 303. A slider 306 is slidably connected inside the sliding groove 305. A bidirectional threaded rod 307 extends from the interior of slide plate 304. A motor 308 is fixedly installed at one end of the bidirectional threaded rod 307. A first damping spring 309 is embedded in the inner wall of slide plate 304. A clamping plate 310 is fixedly installed at one end of the first damping spring 309 extending out of slide plate 304. A limit groove 311 is formed on one side of the first damping spring 309 on the outer wall of slide plate 304. A sensor 312 is embedded inside the limit groove 311. Rotating block 301 forms a rotating structure with connecting plate 2 through rotating shaft 302. Rotating block 301 forms a sliding structure with slide plate 304 through through groove 303. The bidirectional threaded rod 307 is threadedly connected to slider 306. Slider 306 forms a sliding structure with sliding groove 305.

[0030] By adopting the above technical solution, after the metal sheet passes through the main body 1 of the plate rolling machine, it is inserted into the through slot 303 of the rotating block 301. First, it is limited to prevent the sheet from detaching under force during processing, which would affect the processing. At the same time, the rotating block 301 is rotatably connected to the connecting plate 2 through the rotating shaft 302, and can automatically rotate according to the curvature of the metal sheet, thereby avoiding affecting the deformation of the metal sheet. The motor 308 drives the bidirectional threaded rod 307, which causes the slider 306 to slide along the sliding groove 305, thereby driving the sliding plate 304 to slide along the through slot 303. The two sliding plates 304 drive the corresponding clamping plates 310 to... The metal plate is clamped and limited twice to maintain stable conveying. When the clamping plate 310 is under pressure, it compresses the first damping spring 309. At the same time, the clamping plate 310 slides axially along the limiting groove 311 and abuts against the sensor 312 to trigger a signal. After receiving the signal, the control system of the plate rolling machine body 1 stops the motor 308 from rotating, thereby avoiding over-clamping of the metal plate, which would cause the metal plate to be subjected to excessive pressure and arch, thus causing deformation of the metal plate and even affecting its quality. At the same time, it increases the friction force, which affects the smoothness of the metal plate conveying. It can adaptively adjust according to the metal plate to improve convenience and flexibility.

[0031] Specifically, such as Figure 3 , Figure 5 and Figure 6 As shown, the top of the sliding plate 304 has a mounting groove 4, and the mounting groove 4 is equipped with an abutment mechanism 5. The abutment mechanism 5 includes a rotating plate 501, which is rotatably connected to the inside of the mounting groove 4. A support rod 502 extends from one end of the rotating plate 501 through the mounting groove 4. An abutment plate 503 is sleeved on one side of the rotating plate 501 outside the support rod 502. The abutment mechanism 5 also includes a fixing block 504, which is fixedly installed on the top of the rotating block 301. A through rod 506 extends from the inside of the 04. A second damping spring 505 is fixedly installed at one end of the through rod 506 inside the fixed block 504. A connecting frame 507 is fixedly installed at the bottom end of the through rod 506. An abutting roller 508 is rotatably connected between the two axes at the bottom end of the connecting frame 507. A rubber layer 509 is sleeved on the outer wall of the abutting roller 508. The abutting plate 503 forms a rotating structure with the rotating plate 501 through the support rod 502. The support rod 502 and the through rod 506 are perpendicular to each other.

[0032] By adopting the above technical solution, when the two sliding plates 304 slide relative to each other, a rotating plate 501 and abutting plate 503 are rotatably connected via mounting groove 4, respectively. Simultaneously, the contact ends of the rotating plate 501 and abutting plate 503 are rotatably connected via support rod 502. Support rod 502 is fixed between the two protruding rods 506. The rotating plate 501 and abutting plate 503 are tilted downwards, allowing the rotation of the rotating plate 501 and abutting plate 503 to push against the support rod 502 when clamping the metal plate, causing the protruding rod 506 to stretch the second damping spring 505 and then protrude. The fixing block 504 allows the connecting frame 507 to rotate and contact the abutment roller 508 above the metal plate, pressing it to prevent the metal plate from loosening due to force shaking, while also preventing arching and maintaining the smooth conveying of the metal plate. The outer wall of the abutment roller 508 is covered with a rubber layer 509, which can press down on metal plates of different thicknesses through the elasticity of the rubber. After the metal plate is processed, the sliding plate 304 returns to its original position and elastically contracts in conjunction with the second damping spring 505, facilitating the quick reset of the through rod 506 and the connecting frame 507.

[0033] Working Principle: The main body 1 of the plate rolling machine consists of a frame, transmission system, control system, work rollers, and other auxiliary structures, which are existing technologies and will not be described in detail here. It can process metal plates. After processing, the metal plate is inserted into the through slot 303 of the rotating block 301 for initial positioning to prevent slippage. Simultaneously, the rotating block 301 is rotatably connected to the connecting plate 2 via the rotating shaft 302, automatically rotating according to the degree of bending of the metal plate to adapt to different bending levels and prevent deformation caused by limiting or pressing. Subsequently, the motor 308 drives the bidirectional threaded rod 307, causing the slider 306 to drive the sliding plate 304 to slide along the sliding groove 305, thereby clamping the metal plate from both sides. During clamping, when the clamping plate 310 is pressed against the metal plate, it compresses the first damping spring 309, causing the clamping plate 310 to slide axially along the limiting groove 311 and resist the pressure. Sensor 312 senses pressure and sends a signal to the control system, causing motor 308 to stop rotating to prevent over-clamping and arching of the metal plate. When the two sliding plates 304 are displaced, they drive the corresponding rotating plate 501 and contact plate 503 to rotate and press down via support rod 502. The rotating plate 501 and contact plate 503 tilt downwards to facilitate pressing. They rotate automatically via mounting groove 4 and internal rotating shaft, thereby driving through rod 506 to pass through fixed block 504, causing connecting frame 507 to move downwards. This allows contact roller 508 to slide against the metal plate for limiting and pressing to prevent bending and arching, while maintaining smooth conveying. The rubber layer 509 is elastic and can clamp metal plates of different thicknesses. After conveying is completed, motor 308 resets sliding plate 304, and the elastic contraction of second damping spring 505 resets connecting frame 507.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
