Description

Technical Field

[0001] This invention relates to the field of leveling equipment technology, specifically to a leveling equipment for lightweight alloy rolled plates. Background Technology

[0002] Lightweight alloys such as magnesium alloys and aluminum alloys have been widely used in many fields such as aerospace, automobile manufacturing, and electronic equipment due to their advantages such as low density, high specific strength, and good specific stiffness.

[0003] Patent CN222220704U relates to a plate leveling device in the field of lightweight alloy rolling, which solves the problem of plate warping during lightweight alloy plate rolling. It includes three sets of rollers: an upper roller for adjusting plate shape and a lower roller for adjusting plate shape. This device processes the flatness of the plate through a leveling mechanism, reducing the warping deformation of the final rolled product. This effectively reduces the deformation problem of the plate after lightweight alloy rolling, significantly improving the plate shape quality. It eliminates the need for manual tensioning, has a simple and practical structure, high production efficiency, and good practicality. However, when leveling alloy plates of different thicknesses, this device is prone to problems such as insufficient pressure on the alloy plate due to excessive thickness or excessive rolling pressure due to excessive thickness, causing the alloy plate to jam and affecting the normal rolling of the aluminum alloy plate. Therefore, a plate leveling device for lightweight alloy rolling is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flattening device for lightweight alloy rolled plates, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a flattening device for lightweight alloy rolled plates, comprising a base, a support plate fixedly connected to the top of the base, a fixing frame fixedly connected to the front of the support plate, an electric sliding plate fixedly connected to the inner wall of the fixing frame, a chamfering block fixedly connected to the inner wall of the support plate, a threaded rod rotatably connected to the inner wall of the chamfering block, a counterweight plate fixedly connected to the circumferential surface of the threaded rod, a bidirectional lead screw rotatably connected to the inner wall of the fixing frame, and an angled block fixedly connected to the bottom of the counterweight plate. The inner wall of the beveled block is rotatably connected to a pressure roller. A movable plate is threaded onto the circumferential surface of the bidirectional lead screw. A push plate is fixedly connected to the inner wall of the movable plate. The bottom of the counterweight plate has a cleaning structure to prevent pitting on the plate surface. The top of the counterweight plate has a detection mechanism for checking the flatness of the plate. An electric rotating roller is installed on the inner wall of the support plate. A support frame is fixedly connected to the top of the base. When the alloy plate needs to be rolled, the distance between the pressure roller and the electric rotating roller can be precisely adjusted according to the actual thickness of the lightweight alloy plate. The roller gap matches the thickness of the sheet material, providing basic pressure conditions for flattening, thereby improving the adaptability to flattening different sheet materials and avoiding cracking of thin materials or insufficient flattening of thick materials due to fixed spacing. A motor is installed at the top of the threaded rod, which will drive the threaded rod to rotate. A counterweight plate is threadedly connected to the circumference of the threaded rod, and the surface of the counterweight plate is slidably connected to the inner wall of the support plate. A motor is installed on the left side of the bidirectional lead screw, which will drive the bidirectional lead screw to rotate. The push plate is slidably connected to the fixed frame. The top of the support frame is rotatably connected to the bottom of the threaded rod. During the rolling process of the sheet metal, it can ensure that its center line is aligned with the center line of the pressure roller, avoid excessive force on one side due to sheet metal offset, reduce defects such as edge cracking and wavy edges, and improve the edge quality and dimensional accuracy of the sheet metal after flattening. At the same time, the centered sheet metal can make the pressure of the pressure roller surface evenly distributed along the width direction, preventing uneven sheet metal thickness caused by local pressure concentration and collision with the support plate during movement. Especially for easily deformable materials such as lightweight alloys, it can ensure a consistent flatness effect across the entire width.

[0006] Preferably, the cleaning structure includes a connecting plate fixedly connected to the bottom of the counterweight plate. A reciprocating screw is rotatably connected to the inner wall of the connecting plate. A cleaning plate is movably connected to the circumferential surface of the reciprocating screw. A transmission wheel is fixedly connected to the circumferential surface of the reciprocating screw. A fixing ring is fixedly connected to the circumferential surface of the pressure roller. An L-shaped plate is fixedly connected to the top of the counterweight plate. An elastic rod is slidably connected to the inner wall of the L-shaped plate. A shaped block is fixedly connected to the bottom of the elastic rod. A brush roller is rotatably connected to the inner wall of the shaped block. A transmission wheel is fixedly connected to the central axis of the brush roller. During the rolling process, this structure can remove metal debris, oxide scale, and other impurities adhering to the surface of the pressure roller. To prevent impurities from accumulating on the roller surface and causing unevenness between the roller surface and the alloy plate surface, ensuring uniform contact between the pressure roller and the plate, avoiding uneven plate thickness caused by local pressure fluctuations, and ensuring the stability of the leveling process, the circumferential surface of the transmission wheel one is in contact with the circumferential surface of the fixed ring, the surface of the cleaning plate is in contact with the circumferential surface of the pressure roller, and the top of the cleaning plate is in contact with the bottom of the counterweight plate. The brush roller is used to remove impurities from the surface of the plate. During the rolling process of the alloy plate, it can remove impurities from the surface of the plate, reducing the probability of impurities being pressed into the alloy surface layer by the pressure roller during the leveling process, thereby further avoiding the formation of surface defects such as indentations, inclusions, and scratches, and ensuring the appearance quality and surface precision of the plate.

[0007] Preferably, the detection mechanism includes a straight plate fixedly connected to the circumferential surface of an elastic rod. A sensing plate is fixedly connected to the top of the counterweight plate. A sliding rod is slidably connected to the inner wall of the straight plate via a spring. When the alloy plate is unloaded after rolling, the mechanism can detect whether the alloy plate warps and the degree of warping. After the rolling process is complete, the sensing plate can activate an electric sliding plate to automatically re-roll the alloy plate, ensuring that the flattened finished product is free of warping defects, thus improving the final product's pass rate and quality consistency. The sliding rod's rear... The device is fixedly connected to an inclined plate. A round rod is slidably connected to the inner wall of the push plate. A push plate is fixedly connected to the right side of the round rod. A threaded rod is threadedly connected to the inner wall of the push plate. The front part of the sensing plate is in contact with the rear part of the inclined plate. The right side of the threaded rod is rotatably connected to the left side of the push plate. The sensing plate is electrically connected to the electric sliding plate. When centering alloy plates of different sizes is required, the device can adapt to plates of any width without the need to replace the special push components for plates of different widths, which greatly improves the applicability and equipment utilization of the leveling device.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This lightweight alloy rolled sheet leveling device, through the coordinated operation of a base, support plate, fixed frame, electric sliding plate, chamfering block, threaded rod, counterweight plate, double-acting screw, bevel block, pressure roller, moving plate, pushing plate, electric rotating roller, and support frame, allows for precise adjustment of the distance between the pressure roller and the electric rotating roller according to the actual thickness of the lightweight alloy sheet during rolling. This ensures that the roller gap matches the sheet thickness, providing basic pressure conditions for leveling and improving adaptability to leveling different sheets. It also avoids issues caused by fixed spacing. This can lead to cracking of thin materials or insufficient flatness of thick materials. During the rolling process of the sheet metal, it is possible to ensure that its center line is aligned with the center line of the pressure roller, avoiding excessive force on one side due to sheet metal misalignment, reducing defects such as edge cracking and wavy edges, and improving the edge quality and dimensional accuracy of the flattened sheet metal. At the same time, the centered sheet metal can ensure that the pressure on the roller surface is evenly distributed along the width direction, preventing uneven sheet metal thickness caused by local pressure concentration and collision with the support plate during movement. Especially for easily deformable materials such as lightweight alloys, it can ensure a consistent flatness across the entire width.

[0009] 2. This lightweight alloy rolled plate leveling device, through the coordinated operation of the connecting plate, reciprocating screw, cleaning plate, transmission wheel, and fixed ring, can remove metal debris, oxide scale, and other impurities adhering to the surface of the pressure roller during the rolling process. This prevents impurities from accumulating on the roller surface and causing unevenness between the roller surface and the alloy plate surface, ensuring uniform contact between the pressure roller and the plate, avoiding uneven plate thickness caused by local pressure fluctuations, and ensuring the stability of the leveling process.

[0010] 3. This lightweight alloy rolled plate leveling device, through the coordinated operation of L-shaped plate, elastic rod, irregular block, brush roller and transmission wheel, can remove impurities from the plate surface during the alloy plate rolling process, reduce the probability of impurities being pressed into the alloy surface layer by the pressure roller during the leveling process, and further avoid the formation of surface defects such as indentations, inclusions, and scratches, thus ensuring the appearance quality and surface precision of the plate.

[0011] 4. This lightweight alloy rolled plate leveling device, through the coordinated operation of a straight plate, an induction plate, a slide bar, and an inclined plate, can detect whether the alloy plate is warped and the degree of warping when the rolled alloy plate is discharged. Then, after the rolling process is completed, the electric slide bar is activated by the induction plate to automatically re-roll the alloy plate, ensuring that the leveled finished product is free of warping defects and improving the pass rate and quality consistency of the final product.

[0012] 5. This lightweight alloy rolled plate leveling device, through the coordinated operation of the round rod, push plate and threaded rod, can adapt to plates of any width when centering alloy plates of different sizes are required. There is no need to replace the special push components for plates of different widths, which greatly improves the applicability of the leveling device and the utilization rate of the equipment.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-7One embodiment of the present invention is as follows: a flattening device for lightweight alloy rolled plates, comprising a base 1, a support plate 2 fixedly connected to the top of the base 1, a fixed frame 3 fixedly connected to the front of the support plate 2, an electric sliding plate 4 fixedly connected to the inner wall of the fixed frame 3, a chamfering block 5 fixedly connected to the inner wall of the support plate 2, a threaded rod 6 rotatably connected to the inner wall of the chamfering block 5, a counterweight plate 7 fixedly connected to the circumferential surface of the threaded rod 6, a bidirectional lead screw 8 rotatably connected to the inner wall of the fixed frame 3, a beveled block 9 fixedly connected to the bottom of the counterweight plate 7, a pressure roller 10 rotatably connected to the inner wall of the beveled block 9, a moving plate 11 threadedly connected to the circumferential surface of the bidirectional lead screw 8, a push plate 12 fixedly connected to the inner wall of the moving plate 11, a cleaning structure 13 for preventing pits from appearing on the surface of the plate provided at the bottom of the counterweight plate 7, a detection mechanism 14 for detecting whether the plate is flat provided at the top of the counterweight plate 7, an electric rotating roller 15 provided on the inner wall of the support plate 2, and a support frame 16 fixedly connected to the top of the base 1; When the alloy plate needs to be rolled, the operator places the plate to be rolled on top of the electric slide plate 4. At this time, the electric slide plate 4 will start and drive the alloy plate to move backward. Then the alloy plate will come into contact with the electric roller 15. At the same time, the electric roller 15 will start and drive the metal plate to move backward. Before the metal plate comes into contact with the electric roller 15, the motor will start and drive the threaded rod 6 to rotate. The rotation of the threaded rod 6 will drive the counterweight plate 7 to move downward through the threaded groove on the surface. The downward movement of the counterweight plate 7 will drive the bevel block 9 to move downward. The downward movement of the bevel block 9 will drive the pressure roller 10 to move downward. Thus, the distance between the pressure roller 10 and the electric roller 15 can be precisely adjusted according to the actual thickness of the lightweight alloy plate to ensure that the roller gap matches the plate thickness, providing basic pressure conditions for flattening, thereby improving the adaptability to flattening different plates and avoiding the cracking of thin materials or insufficient flattening of thick materials due to fixed spacing. During the rolling process, the pressure roller 10 will come into contact with the plate and will be driven to rotate by friction. A motor is installed at the top of the threaded rod 6, and the threaded rod 6 will be driven to rotate by the motor. A counterweight plate 7 is threadedly connected to the circumferential surface of the threaded rod 6. The surface of the counterweight plate 7 is slidably connected to the inner wall of the support plate 2. A motor is installed on the left side of the bidirectional screw 8, and the bidirectional screw 8 will be driven to rotate by the motor. The push plate 12 is slidably connected to the fixed frame 3. The top of the support frame 16 is rotatably connected to the bottom of the threaded rod 6. When the alloy plate is on top of the electric sliding plate 4 and ready for rolling, the motor starts and drives the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 drives the moving plate 11 to move in the opposite direction through the threaded groove on its surface. The movement of the moving plate 11 drives the pushing plate 12 to move. During the movement of the pushing plate 12, it will contact the alloy plate and push the alloy plate towards the center, thereby ensuring that its center line is aligned with the center line of the pressure roller 10. This avoids excessive force on one side due to plate offset, reduces defects such as edge cracking and wavy edges, and improves the edge quality and dimensional accuracy of the plate after flattening. At the same time, the centrally located plate can make the pressure of the pressure roller 10 evenly distributed along the width direction, preventing uneven plate thickness caused by local pressure concentration and collision with the support plate 2 during movement. Especially for easily deformable materials such as lightweight alloys, it can ensure a consistent flatness effect across the entire width.

[0017] Working principle: When the alloy plate needs to be rolled, the operator places the plate to be rolled on top of the electric slide plate 4. At this time, the electric slide plate 4 will start and drive the alloy plate to move backward. Then the alloy plate will come into contact with the electric roller 15. The distance between the pressure roller 10 and the electric roller 15 can be precisely adjusted according to the actual thickness of the lightweight alloy plate to ensure that the roller gap matches the plate thickness and provide basic pressure conditions for flatness. When the alloy plate is on top of the electric slide plate 4 and ready for rolling, the motor will start and drive the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 will drive the moving plate 11 to move in the opposite direction through the threaded groove on the surface. The movement of the moving plate 11 will drive the push plate 12 to move. During the movement of the push plate 12, it will come into contact with the alloy plate and push the alloy plate to move towards the center, thereby ensuring that its center line is aligned with the center line of the pressure roller 10 and avoiding excessive force on one side due to plate offset.

[0018] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the cleaning structure 13 includes a connecting plate 131, which is fixedly connected to the bottom of the counterweight plate 7. A reciprocating screw 132 is rotatably connected to the inner wall of the connecting plate 131. A cleaning plate 133 is movably connected to the circumferential surface of the reciprocating screw 132. A transmission wheel 134 is fixedly connected to the circumferential surface of the reciprocating screw 132. A fixing ring 135 is fixedly connected to the circumferential surface of the pressure roller 10. An L-shaped plate 136 is fixedly connected to the top of the counterweight plate 7. An elastic rod 137 is slidably connected to the inner wall of the L-shaped plate 136. A shaped block 138 is fixedly connected to the bottom of the elastic rod 137. A brush roller 139 is rotatably connected to the inner wall of the shaped block 138. A transmission wheel 1310 is fixedly connected to the central axis of the brush roller 139. During the rolling process, the rotation of the pressure roller 10 drives the fixed ring 135 to rotate. The rotation of the fixed ring 135 contacts the transmission wheel 134 and drives the transmission wheel 134 to rotate through friction. The rotation of the transmission wheel 134 drives the reciprocating screw 132 to rotate. The rotation of the reciprocating screw 132 drives the cleaning plate 133 to move through the reciprocating thread groove on its surface. During the movement of the cleaning plate 133, it contacts the surface of the reciprocating screw 132, thereby removing metal debris, oxide scale and other impurities adhering to the surface of the pressure roller 10. This prevents impurities from accumulating on the roller surface and causing unevenness between the roller surface and the alloy plate surface, ensuring uniform contact between the pressure roller 10 and the plate, avoiding uneven plate thickness caused by local pressure fluctuations, and ensuring the stability of the flattening process. The circumferential surface of the drive wheel 134 is in contact with the circumferential surface of the fixed ring 135, the surface of the cleaning plate 133 is in contact with the circumferential surface of the pressure roller 10, the top of the cleaning plate 133 is in contact with the bottom of the counterweight plate 7, and the brush roller 139 is used to remove impurities from the surface of the plate. During the alloy sheet rolling process, the counterweight plate 7 moves downward, which drives the L-shaped plate 136 to move. The movement of the L-shaped plate 136 drives the elastic rod 137 to move downward. The movement of the elastic rod 137 drives the irregular block 138 to move. The movement of the irregular block 138 drives the transmission wheel 1310 to move. During the movement of the transmission wheel 1310, it comes into contact with the top of the alloy sheet and generates friction during the movement of the alloy sheet, which enables the transmission wheel 1310 to rotate. The rotation of the transmission wheel 1310 drives the brush roller 139 to rotate, thereby removing impurities from the surface of the sheet and reducing the probability of impurities being pressed into the alloy surface by the pressure roller 10 during the flattening process. This further avoids the formation of surface defects such as indentations, inclusions, and scratches, ensuring the appearance quality and surface precision of the sheet.

[0019] Working principle: During the rolling process, the rotation of the pressure roller 10 drives the fixed ring 135 to rotate. The rotation of the fixed ring 135 contacts the transmission wheel 134 and drives the transmission wheel 134 to rotate through friction, thereby removing metal debris, oxide scale and other impurities adhering to the surface of the pressure roller 10, preventing impurities from accumulating on the roller surface and causing unevenness between the roller surface and the alloy plate surface. During the rolling process of the alloy plate, the counterweight plate 7 moves downward and drives the L-shaped plate 136 to move. During the movement of the transmission wheel 1310, it contacts the top of the alloy plate and generates friction during the movement of the alloy plate, enabling the transmission wheel 1310 to rotate. The rotation of the transmission wheel 1310 drives the brush roller 139 to rotate, thereby removing impurities from the surface of the plate.

[0020] The detection mechanism 14 includes a straight plate 141, which is fixedly connected to the circumferential surface of the elastic rod 137. A sensing plate 142 is fixedly connected to the top of the counterweight plate 7. A sliding rod 143 is slidably connected to the inner wall of the straight plate 141 via a spring. An inclined plate 144 is fixedly connected to the rear of the sliding rod 143. A round rod 145 is slidably connected to the inner wall of the push plate 12. A push plate 146 is fixedly connected to the right side of the round rod 145. A threaded rod 147 is threadedly connected to the inner wall of the push plate 12. When the rolled alloy plate is discharged, it will come into contact with the second transmission wheel 1310 again. If the alloy plate warps, it will exert an upward thrust on the second transmission wheel 1310, causing it to move upward and drive the L-shaped plate 136 upward. The upward movement of the L-shaped plate 136 will drive the irregular block 138 upward, which in turn will drive the elastic rod 137 upward. The movement of the elastic rod 137 will drive the straight plate 141 upward, which will then drive the sliding rod 143 upward. The movement will cause the inclined plate 144 to move upward. At this time, the slide bar 143 will move to the left through the spring. The leftward movement of the slide bar 143 will cause the inclined plate 144 to move to the left, so that the inclined plate 144 can be stuck in the inner wall of the induction plate 142. This allows the detection of whether the alloy plate is warped and the degree of warping. After the rolling process is completed, the electric slide bar 4 can be activated by the induction plate 142 to automatically re-roll the alloy plate, ensuring that the flattened finished product is free of warping defects and improving the pass rate and quality consistency of the final product. The front part of the induction plate 142 is in contact with the rear part of the inclined plate 144, the right side of the threaded rod 147 is rotatably connected to the left side of the push plate 146, and the induction plate 142 is electrically connected to the electric sliding plate 4. When centering alloy plates of different sizes is required, the operator can rotate the threaded rod 147 by turning a knob. The rotation of the threaded rod 147 will cause it to move to the right through the threaded groove on its surface. The movement of the threaded rod 147 to the right will drive the push plate 146 to move, and the movement of the push plate 146 to the right will drive the round rod 145 to move. This allows the device to adapt to plates of any width without the need to replace the special push components for plates of different widths, greatly improving the applicability and equipment utilization of the leveling device.

[0021] Working principle: When the rolled alloy plate is discharged, it will come into contact with the transmission wheel 1310 again. If the alloy plate warps, it will exert an upward thrust on the transmission wheel 1310, causing it to move upward and drive the L-shaped plate 136 upward. The upward movement of the L-shaped plate 136 will drive the irregular block 138 upward, which will drive the elastic rod 137 upward. The movement of the elastic rod 137 will drive the straight plate 141 upward, which will drive the sliding rod 143 upward. This can detect whether the alloy plate is warped and the degree of warping. When centering alloy plates of different sizes is required, the operator can rotate the threaded rod 147 by turning the knob. The rotation of the threaded rod 147 will cause it to move to the right through the threaded groove on its surface, thus allowing the device to adapt to plates of any width.
