Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to a metal coil flattening device. Background Art
[0002] In the sheet metal processing industry, especially in the production of color-coated sheets, metal coils are the basic materials, and their quality directly affects the appearance and performance of the finished products.
[0003] After uncoiling, the metal coil will form a natural curl state, so it must be leveled to eliminate the curling deformation and ensure the flatness of the metal strip after leveling, so as to meet the subsequent processing requirements such as painting, shearing, and forming.
[0004] Existing metal coil leveling devices have limitations. The spacing between the upper and lower rollers is fixed and cannot be adjusted, and cannot adapt to metal coils of different thicknesses. This may cause excessive leveling or insufficient leveling, affecting the flatness of the metal strip and subsequent processing. Utility Model Content
[0005] The utility model aims to provide a metal coil flattening device with high flexibility and wide application range in view of the above problems existing in the prior art.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A metal coil leveling device, characterized in that it includes a base, a lower roller assembly, an upper roller assembly and a lifting assembly, the base is rectangular when viewed from above and is concave when viewed from the side, the lower roller assembly includes a plurality of lower leveling rollers, and the plurality of lower leveling rollers are rotatably connected to the notch of the base, the lifting assembly is connected above the base, the lifting assembly is connected to the upper roller assembly and the lifting assembly can drive the upper roller assembly to move up and down, the upper roller assembly includes a plurality of upper leveling rollers, both ends of the plurality of upper leveling rollers are rotatably connected to the lifting assembly, and the plurality of upper leveling rollers are respectively arranged opposite to the plurality of lower leveling rollers up and down.
[0008] The metal coil flattening device is used to flatten the uncoiled metal coil and eliminate its curling deformation to form a flat metal strip.
[0009] The leveling device provides a stable installation platform by arranging a base to stably support the lower roller assembly and the lifting assembly; the lifting assembly is provided to drive the upper roller assembly to move up and down, so that the spacing between the upper roller assembly and the lower roller assembly is adjustable, and can be flexibly adjusted according to the actual thickness of the metal coil. Whether it is thicker or thinner metal coils, suitable leveling effects can be obtained, effectively improving the applicability and flexibility of the device; by arranging the upper roller assembly and the lower roller assembly, a plurality of upper leveling rollers and the lower leveling rollers are opposite to each other, ensuring that both sides of the metal coil can be subjected to uniform pressure multiple times when passing through the leveling device, effectively eliminating the curling deformation of the metal coil and improving the flatness, and the upper leveling roller and the lower leveling roller can both rotate circumferentially, reducing resistance during the leveling process, not affecting the transportation of the metal coil, and reducing the possibility of surface damage to the metal coil.
[0010] In the above-mentioned metal coil leveling device, four support columns are respectively fixedly connected to the four corners of the base, a support plate is commonly fixedly connected to the four support columns, the above-mentioned lifting assembly is fixedly connected to the support plate, and the above-mentioned upper roller assembly is located below the support plate.
[0011] The support column provides a stable support for the support plate, and the support plate provides a stable connection carrier for the lifting assembly, thereby ensuring the operational stability of the lifting assembly driving the upper roller assembly to move up and down.
[0012] In the above-mentioned metal coil leveling device, the lifting assembly includes two lifting units, and the two lifting units are symmetrically arranged at both ends of the upper leveling roller.
[0013] The two lifting units provide a stable suspension platform for the upper leveling rollers, ensuring the stable axial connection of the upper leveling rollers. At the same time, the two lifting units synchronously control the up and down translation of the upper leveling rollers to improve the movement accuracy and stability.
[0014] In the above-mentioned metal coil leveling device, the lifting unit includes a cylinder and a slider. The cylinder is fixedly connected to the support plate and the piston rod of the cylinder passes downward through the support plate. The slider is fixedly connected to the end of the piston rod. The above-mentioned several upper leveling rollers are rotatably connected to the slider.
[0015] The cylinder drives the slider to move up and down, and the slider drives several leveling rollers connected to the slider to move synchronously. The cylinders in the two lifting units operate synchronously, so that the several leveling rollers always remain in a horizontal state and always face the lower leveling roller during the synchronous movement of the two sliders, and stop at an appropriate height position according to the actual thickness of the metal coil, which helps to improve the uniformity and stability of the leveling process, thereby improving the flatness of the metal strip after leveling.
[0016] In the above-mentioned metal coil leveling device, the number of the cylinders is several, and the several cylinders are evenly distributed along the length direction of the slider.
[0017] The arrangement of the plurality of cylinders can provide more stable support and adjustment capability, so that the slider and the plurality of upper leveling rollers are more stable during the up and down movement and are not prone to tilting or deflection.
[0018] In the above-mentioned metal coil leveling device, the sliding block is slidably connected to the support columns at both ends of the sliding block.
[0019] The support columns at both ends of the slider limit the slider, so that the slider always maintains a vertical downward direction during the up and down translation process and is not easy to tilt left or right.
[0020] In the above-mentioned metal coil leveling device, two support columns at both ends of the slider are provided with slide grooves on opposite sides thereof, the slide grooves match the slider, and the two ends of the slider are respectively slidably connected in the two slide grooves.
[0021] The slide groove further limits the slider, so that the slider always moves along the direction of the slide groove during the up and down translation process, limiting the left and right tilting and the front and back tilting of the slider.
[0022] In the above-mentioned metal coil leveling device, the upper surface of the lower leveling roller is flush with the upper surface of the base.
[0023] In the above-mentioned metal coil leveling device, the lower surface of the upper leveling roller is flush with the lower surface of the slider.
[0024] The limit of the downward movement of the cylinder-driven slider is that the lower surface of the slider abuts against the upper surface of the base, and the upper surface of the lower leveling roller is flush with the upper surface of the base, and the lower surface of the upper leveling roller is flush with the lower surface of the slider, which can ensure that the upper leveling roller can move downward at most to fit perfectly with the lower leveling roller without excessive downward pressure causing damage.
[0025] Compared with the prior art, the metal coil leveling device provides stable support for the entire device through the arrangement of a base, support columns, and support plates to ensure operational stability; a lifting assembly is arranged to drive the upper roller assembly to move up and down, so that the spacing between the upper roller assembly and the lower roller assembly is adjustable, and can be flexibly adjusted according to the actual thickness of the metal coil. Whether it is thicker or thinner metal coils, a suitable leveling effect can be obtained, effectively improving the applicability and flexibility of the device. BRIEF DESCRIPTION OF THE DRAWINGS
