Description

Technical Field

[0001] This utility model relates to the field of steel coil feeding technology, and in particular to a leveling mechanism for steel coil feeding. Background Technology

[0002] Steel coils are finished products made by continuously rolling hot-rolled or cold-rolled steel plates in steel mills. They are easy to store, transport and process, and are widely used in automobile manufacturing, home appliance production, building materials, pipe manufacturing and other fields. During the rolling process, the steel plate is easily subjected to external forces to generate internal stress. After uncoiling, it is prone to deformation such as warping, wavy lines and sickle bends, and cannot be processed directly. Therefore, leveling treatment is required.

[0003] In existing technologies for flattening steel coils, a cylinder fixed to the top plate provides driving force, pushing a pressure arm downwards to flatten the coil. However, because the cylinder-driven pressure arm cannot move flexibly horizontally, it is difficult to precisely adjust the pressure arm according to the actual flattened area of ​​the coil. This makes it difficult to adapt to diverse flattening operation requirements and reduces the overall flexibility and operability of the device. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the cylinder-driven pressure arm cannot move flexibly horizontally, making it difficult to make precise adjustments to the pressure arm according to the actual flattening part of the steel coil. Therefore, a leveling mechanism for feeding steel coils is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leveling mechanism for feeding steel coils includes a worktable, a lower pressure arm fixedly mounted on the worktable, a movable frame corresponding to the lower pressure arm slidably mounted on the worktable, a connecting plate slidably mounted on the movable frame, a cylinder fixedly connected to the bottom of the connecting plate, an upper pressure arm fixedly connected to the telescopic end of the bottom of the cylinder, and further includes;

[0007] Drive component one is disposed on the worktable and is used to drive the moving frame to slide horizontally.

[0008] Drive component two is disposed on the movable frame and is used to drive the connecting plate to slide horizontally.

[0009] Preferably, the driving component one includes:

[0010] A pair of rotating shafts are rotatably connected to the movable frame.

[0011] The gear is fixedly sleeved on the rotating shaft;

[0012] A rack is fixedly connected to the top of the worktable, and the gear meshes with the rack;

[0013] Motor 1 is fixedly connected to the movable frame and drives one of the rotating shafts to rotate.

[0014] Preferably, the driving component one further includes:

[0015] A slide rail is formed on the top of the workbench, and the movable frame and the slide rail are horizontally slidably connected.

[0016] The plate body is fixedly connected to the movable frame;

[0017] A sliding opening is formed on the worktable, and the sliding opening and the sliding groove are connected. The plate is embedded and horizontally slidably connected in the sliding opening.

[0018] Preferably, the second driving component includes:

[0019] The screw is rotatably connected to the movable frame;

[0020] Motor 2 is fixedly connected to the movable frame and drives the screw to rotate.

[0021] Preferably, the second driving component further includes:

[0022] The movable blocks, arranged in pairs, are fixedly connected to the top of the connecting plate, and the movable blocks are threadedly connected to the screw.

[0023] A limiting groove is formed on the movable frame, and the movable block and the limiting groove are horizontally slidably connected.

[0024] Preferably, a pair of limiting rods are fixedly connected to the top of the upper pressure arm, and the limiting rods slide vertically through the connecting plate.

[0025] Preferably, the top of the workbench is threaded with a bolt, and a baffle is rotatably connected to the bolt, and the baffle is in contact with the vertical side wall of the lower pressure arm.

[0026] Preferably, the top of the workbench has several threaded grooves at equal intervals to facilitate the threaded connection of the bolts.

[0027] Compared with the prior art, the advantages of this utility model are as follows:

[0028] This invention, through the arrangement of drive assembly one and drive assembly two, allows the steel coil to be placed horizontally on the appropriate lower pressure arm. Motor one is then started to drive the rotating shaft, adjusting the front-to-back position of the upper pressure arm via gear meshing with a rack and pinion. Motor two is then started to drive the screw to rotate, adjusting the left-to-right horizontal position of the upper pressure arm. Once adjustment is complete, a cylinder drives the upper pressure arm to move downwards, completing the leveling operation. This effectively ensures the accuracy of leveling, further enhancing the overall flexibility and adjustability of the device, and meeting diverse operational needs. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Reference Figures 1-3A leveling mechanism for steel coil loading includes a worktable 1. A lower pressure arm 2 is fixedly mounted on the worktable 1, forming an upper pressure arm 6 in a corresponding structure. When the lower pressure arm 2 receives the steel coil, it cooperates with the pressing action of the upper pressure arm 6 to ensure that the steel coil remains stable during the leveling process, providing reliable bottom support for subsequent uniform leveling and effectively improving the consistency of the leveling effect. A movable frame 3 corresponding to the lower pressure arm 2 is horizontally slidably mounted on the worktable 1. A connecting plate 4 is horizontally slidably mounted on the movable frame 3. A cylinder 5 is fixedly connected to the bottom of the connecting plate 4. The telescopic end of the bottom of the cylinder 5 is fixedly connected to the upper pressure arm 6. The cylinder 5 is the power source for driving the upper pressure arm 6 to rise and fall, and can flexibly adjust the pressing force of the upper pressure arm 6 according to the thickness and material of the steel coil, ensuring that the steel coil is fully leveled while avoiding damage to the surface of the steel coil due to excessive pressure. It also includes;

[0041] Drive component one is set on the worktable 1 and is used to drive the moving frame 3 to slide horizontally.

[0042] Drive component two is set on the movable frame 3 and is used to drive the connecting plate 4 to slide horizontally.

[0043] Reference Figures 1-2 The drive assembly includes: a rotating shaft 31, a gear 32, a rack 33, and a motor 34.

[0044] A pair of rotating shafts 31 are rotatably connected to the movable frame 3. The rotating shafts 31 not only provide a stable mounting surface for the gears 32, but also ensure synchronous rotation of the gears 32 through their paired arrangement. The balanced force on both sides of the rotating shafts 31 prevents the movable frame 3 from tilting due to excessive force on one side during sliding, ensuring smooth sliding along the slide groove 35 and improving the stability and reliability of the drive assembly. The gear 32 is fixedly mounted on the rotating shaft 31; the rack 33 is fixedly connected to the top of the worktable 1, and the gear 32 and rack 33 mesh; the motor 34 is fixedly connected to the movable frame 3, and drives one of the rotating shafts 31 to rotate. The motor 34 adjusts the front-to-back position of the upper pressure arm 6, moving it to the precise leveling position.

[0045] The drive assembly also includes: a slide 35, a plate 36, and a slide opening 37.

[0046] A slide groove 35 is formed on the top of the worktable 1, and the movable frame 3 and the slide groove 35 are horizontally slidably connected; a plate 36 is fixedly connected to the movable frame 3; a sliding opening 37 is formed on the worktable 1, and the sliding opening 37 and the slide groove 35 are connected through each other, with the plate 36 embedded and horizontally slidably connected within the sliding opening 37. The plate 36, in conjunction with the slide groove 35, further restricts the movement trajectory of the movable frame 3, enhancing the sliding stability of the movable frame 3. When the movable frame 3 slides along the slide groove 35, the plate 36 slides synchronously within the sliding opening 37, preventing the movable frame 3 from warping or wobbling due to uneven force, ensuring that the overall force on the movable frame 3 is balanced, and improving the smoothness of the operation of the drive assembly.

[0047] Reference Figures 1-2 The second drive component includes: a screw 41 and a second motor 42.

[0048] The screw 41 is rotatably connected to the movable frame 3; the second motor 42 is fixedly connected to the movable frame 3, and the second motor 42 drives the screw 41 to rotate.

[0049] The second drive component also includes: a moving block 43 and a limiting groove 44.

[0050] A pair of movable blocks 43 are fixedly connected to the top of the connecting plate 4, and the movable blocks 43 and the screw 41 are threaded together; a limiting groove 44 is formed on the movable frame 3, and the movable blocks 43 and the limiting groove 44 are horizontally slidably connected. The limiting groove 44 can prevent the movable blocks 43 from rotating when they follow the screw 41, ensuring that the movable blocks 43 slide only in the horizontal direction, thereby ensuring the stability of the left and right lateral adjustment trajectory of the connecting plate 4.

[0051] A pair of limiting rods 61 are fixedly connected to the top of the upper pressure arm 6, and the limiting rods 61 slide vertically through the connecting plate 4. The limiting rods 61 can effectively restrict the lifting direction of the upper pressure arm 6, prevent it from shifting laterally or tilting during the lifting process, and further improve the leveling accuracy.

[0052] The top of the workbench 1 is threaded with a bolt 8, and a baffle 7 is rotatably connected to the bolt 8, and the baffle 7 is in contact with the vertical side wall of the lower pressure arm 2.

[0053] The top of the workbench 1 has several threaded grooves 9 at equal intervals to facilitate the threaded connection of bolts 8. The threaded grooves 9 provide threaded connection positions for bolts 8, and their equidistant layout can provide multiple adjustment positions for bolts 8, thereby satisfying the limitation and fixation of the lower pressure arm 2 in the horizontal direction.

[0054] The functional principle of this utility model can be explained through the following operation methods:

[0055] When using the steel coil feeding leveling mechanism, first connect the bolt 8 to the threaded groove 9 on the top of the workbench 1, adjust the position of the baffle 7, and rotate the bolt 8 to make the baffle 7 contact the vertical side wall of the lower pressure arm 2, thus completing the limiting of the lower pressure arm 2.

[0056] Place the steel coil material on the lower pressure arm 2;

[0057] Start drive component one: motor one 34 drives the rotating shaft 31 to rotate, the gear 32 fixed on the rotating shaft 31 meshes with the rack 33 on the top of the worktable 1, driving the moving frame 3 to slide horizontally back and forth along the slide groove 35 (the plate 36 slides synchronously in the slide 37 for auxiliary guidance), and adjust the position of the moving frame 3 to match the part of the material to be leveled.

[0058] Next, drive component two is started: motor two 42 drives screw 41 to rotate, and moving block 43, which is threadedly connected to screw 41, slides along limit groove 44, causing connecting plate 4 to slide horizontally left and right on moving frame 3, adjusting the lateral position of upper pressure arm 6.

[0059] Subsequently, the telescopic end of cylinder 5 extends, causing the upper pressure arm 6 to descend and cooperate with the lower pressure arm 2 to press the steel coil material (the limiting rod 61 at the top of the upper pressure arm 6 slides vertically along the connecting plate 4 to ensure stable downward pressure).

[0060] After leveling is completed, cylinder 5 retracts to raise the upper pressure arm 6, and drive components one and two reverse to reset the moving frame 3 and connecting plate 4. The leveled steel coil can then be removed.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
