Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum alloy plate processing equipment, in particular to a high-strength aluminum alloy plate straightening and flattening device. BACKGROUND

[0002] High-strength aluminum alloy plates are widely used in industrial manufacturing due to their excellent mechanical properties. In the production process, the plates often need to go through a straightening and flattening process to eliminate internal stress and ensure surface flatness. The existing straightening and flattening equipment usually uses multiple sets of upper and lower rollers to continuously roll the plate, and achieves the flatness of the plate through repeated bending deformation.

[0003] However, in actual processing, the existing flattening device mostly adopts a rigid pressing structure, that is, the gap between the pressing wheel and the transmission roller is fixed once set, or only the overall lifting is realized through the hydraulic cylinder. When there are local protrusions or uneven thickness on the surface of the aluminum alloy plate due to the previous process, the rigid pressing wheel cannot adaptively avoid, resulting in excessive local extrusion force on the protruding part. This not only easily causes indentation, damage or even local rupture on the surface of the plate, but also may impact the equipment bearings in the opposite direction, shortening the service life of the equipment.

[0004] In addition, the production workshop environment is usually accompanied by dust or metal chips, and the surface of the aluminum alloy plate is easy to adsorb small particles during transmission. The existing flattening equipment often lacks effective online cleaning mechanisms, or only uses simple blowing devices, which is difficult to cover the entire plate width for thorough cleaning. When impurities attached to the surface of the plate enter the high-pressure flattening roller system, the impurities will be forced into the surface of the plate, forming difficult-to-repair pits or dents, which seriously affect the surface quality of high-quality aluminum alloy plates.

[0005] At the same time, different batches of aluminum alloy plates have different width specifications. The traditional conveying mechanism mostly uses fixed guide plates or manual adjustment of limiting devices, which has low adjustment efficiency and poor accuracy. If the limit is not accurate, the plate is easy to deviate laterally when passing through the flattening roller, resulting in uneven stress and affecting the flattening effect. In severe cases, it may even cause material jamming failure, which is difficult to meet the needs of efficient and high-precision automatic production. SUMMARY

[0006] In view of the shortcomings of the prior art, the present application provides a high-strength aluminum alloy plate straightening and flattening device, which solves the technical problems that the existing straightening and flattening equipment usually adopts a rigid pressing structure, which is difficult to adapt to the protrusions on the surface of the plate, resulting in local damage to the plate or damage to the equipment due to impact, and dust and impurities are pressed into the surface of the plate during the flattening process due to the lack of effective full-coverage cleaning means, resulting in defects, and the conveying guide adjustment is not convenient and easy to cause the plate to deviate during conveying.

[0027] In order to adapt to different widths of the plate and prevent deviation, the limiting assembly 6 is arranged below the transmission. The assembly includes a positioning column 611 which is in close contact with the surface of the electric transmission roller 2. One side of the cabinet 1 is fixedly connected with a first fixed block 602, and the first fixed block 602 is mounted with a second motor 601 on one side. The bottom of the electric transmission roller 2 is provided with a second connecting plate 605, and the two sides of the second connecting plate 605 are fixedly connected with third sliding plates 606.

The bottom of the second connecting plate 605 is fixedly connected with third connecting blocks 604 on both sides, one of which is internally threadedly connected with a threaded rod 603, and the other end of the threaded rod 603 is rotatably connected with a second fixed block 607 which is fixed to the inner wall of the cabinet 1. The inner wall of the other third connecting block 604 is slidingly connected with a second limiting rod 608, and the two ends of the second limiting rod 608 are fixed to the inner wall of the cabinet 1 through a third fixed block 609.

[0028] Working principle: During equipment use, the telescopic cylinder 401 first drives the pressure roller 405 at the bottom of the first connecting block 406 to move to a designated position, so that the distance between the pressure roller 405 and the electric drive roller 2 reaches the expected level. Then, a specific aluminum alloy sheet is placed on top of the electric drive roller 2. Subsequently, the electric drive roller 2 is started, driving it to rotate and moving the aluminum alloy sheet. During this process, the dust extraction fan 511 is started, and the suction power of the dust extraction fan 511 is used to absorb dust or fine particulate impurities on the surface of the aluminum alloy sheet through the absorption cover 509 and the first connecting hose 510 to a designated position at the end of the second connecting hose 512. At the same time, the first motor 501 is started, and the output end of the first motor 501 drives the pulley assembly 503 to run. The second connecting block 505 and the slider 506 drive the third connecting frame 504 to move, and the T-shaped slider 507 slides on the groove surface of the inner wall of the second connecting frame 502, limiting the movement direction of the third connecting frame 504. When the second connecting block 505 moves to one side of the pulley group 503, the running force of the pulley group 503 will drive the second connecting block 505 to move from one side to the other side, and the slider 506 will slide on the inner wall of the third connecting frame 504. Then the running force of the pulley group 503 will drive the third connecting frame 504 to continue moving in the opposite direction, thereby driving the absorption cover 509 to move back and forth on the top of the aluminum alloy, thoroughly cleaning the dust and fine particles on its surface, and avoiding affecting the subsequent leveling effect. Next, the second motor 601 is started, and the output end of the second motor 601 drives the threaded rod 603 to rotate. The third connecting block 604 on one side drives the second connecting plate 605 at the top to move, and the third sliding plate 606 slides on the inner wall of the second sliding groove 613. During this process, the third connecting block 604 on the other side slides on the surface of the second limiting rod 608. At the same time, the guide groove 610 drives the positioning posts 611 on both sides to slide in opposite directions between two adjacent electric drive rollers 2. The positioning posts 611 on both sides limit the movement direction of the electric drive rollers 2 and position the aluminum alloy plate to prevent its position from shifting. When the aluminum alloy plate is moved by the rotating force of the motor-driven transmission roller 2, the top pressing roller 405 will perform flattening treatment. When the protrusion on the top of the aluminum alloy plate contacts the surface of the pressing roller 405, the pressing roller 405 will be moved upward, the second sliding plate 407 on the top of the first connecting block 406 will be slid in the inner wall of the fixed shell 412 through the first connecting frame 411, the limiting strip 409 will be slid in the first sliding groove 410, and the spring 408 will be compressed. The elastic characteristics of the spring 408 provide a certain activity space for the pressing roller 405, and the rebounding force of the spring 408 will increase the downward pressure of the pressing roller 405 on the protruding part on the top of the aluminum alloy plate, so that the downward pressure of the equipment can be self-adapted to the concave-convex surface on the top of the aluminum alloy plate, preventing the whole flattening roller from being pressed on the protruding part on the top of the aluminum alloy plate, causing local damage of the aluminum alloy plate, and enhancing the self-adaptability of the equipment.
