Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel strip leveling technology, and more specifically, to a steel strip leveling device. Background Technology
[0002] A steel strip screed is a specialized piece of equipment that uses multiple sets of staggered rollers to apply repeated bending stress to the steel strip, thereby eliminating internal residual stress and unevenness defects. The equipment mainly consists of an uncoiling device, a guiding mechanism, a screed main unit (including upper and lower working roller sets), a drive system, tension control, and a winding device. By adjusting parameters such as roller gap, pressure, and screed speed, it can effectively correct deformations such as wavy edges and warping of the steel strip. Advanced screeds are also equipped with intelligent control systems and segmented pressure adjustment functions, adapting to the processing needs of steel strips of different materials and thicknesses. They are widely used in industries such as metal products, automobiles, and electronics, ensuring that the steel strip meets the flatness requirements for subsequent precision processing.
[0003] During the production and processing of steel strip, the transfer and unfolding conveying stages easily lead to the accumulation of various contaminants on its surface. Due to the electrostatic adsorption properties of the steel strip surface, dust particles from the environment will adhere during storage, stacking, and transportation; simultaneously, the friction between the steel strip and the equipment rollers during uncoiling and unfolding will generate trace amounts of metal debris. These contaminants mainly include suspended particles in the air and iron powder generated by equipment wear. If they are not effectively cleaned, these impurities will be pressed into the steel strip surface during the subsequent leveling process, not only affecting the leveling effect of the leveling rollers and causing uneven leveling, but also potentially causing defects such as scratches and indentations on the steel strip surface. More seriously, hard particles may damage the working surface of the precision leveling rollers during high-pressure leveling, shortening the service life of the equipment. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the problems existing in the prior art, this utility model provides a steel strip leveling device to solve the technical problem mentioned in the background art that the surface of the steel strip is not easy to clean before leveling, which affects the leveling effect of the steel strip.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A steel strip leveling device includes a leveling machine body, which includes a frame. Multiple lower pressure rollers are mounted on the frame, and a protective cover is mounted on the frame. An upper pressure roller is mounted above the lower pressure rollers and is vertically adjustable within the protective cover. A feeding frame is located at the front end of the frame, and feeding rollers are mounted on the feeding frame. Two limiting rollers are symmetrically arranged between two feeding rollers. A movable adjustment structure is provided on the feeding frame in conjunction with the two limiting rollers. An electric push rod is located at the front end of the protective cover, and an air blowing box is located at the bottom end of the electric push rod. An air blowing port is obliquely downwards from the air blowing box.
[0009] The present invention is further configured such that a suction hood is provided at the front end of the blower box, a dust suction pipe is connected to the suction hood, a dust collection box is connected to the tail end of the dust suction pipe, and a negative pressure fan is provided on the dust collection box. When the negative pressure fan is started, a negative pressure is generated at the suction hood, which can absorb the surface dust blown out by the blower box and prevent the dust from falling back onto the steel belt. The dust will be transported to the dust collection box for collection through the dust suction pipe. The dust collection box is a known existing device, and its structure will not be described in detail in the present invention.
[0010] The present invention is further configured such that a flexible air supply hose is provided between the output end of the negative pressure fan and the air blowing box. In this way, the airflow output by the negative pressure fan can be transported to the air blowing box through the flexible air supply hose and blown onto the steel belt to be leveled through the air outlet, thereby cleaning the dust on the surface of the steel belt. This realizes multiple uses of a set of equipment, improves the utilization effect of the equipment, and reduces the equipment cost.
[0011] The present invention is further configured such that the movable adjustment structure includes a bidirectional screw, which is mounted on the feeding frame via bearings, and an adjustment motor is driven to one end. An adjustment block is provided at the bottom end of the limiting roller, and the adjustment block is threaded onto the bidirectional screw. When the adjustment motor is started, the bidirectional screw is rotated by the adjustment motor. The movement of the limiting roller can be controlled by the cooperation between the bidirectional screw and the adjustment block, so as to realize the flexible adjustment of the installation position of the limiting roller, thereby realizing the limiting of steel strips of different widths during feeding. Here, a limiting rod can be set on the feeding frame so that the adjustment block slides on the limiting rod for limiting the movement of the adjustment block. At the same time, the limiting roller is rotatably mounted on the adjustment block.
[0012] The present invention is further configured such that a hydraulic cylinder is provided inside the protective cover, a pressing frame is provided at the bottom end of the hydraulic cylinder, and the upper pressure roller is provided on the pressing frame. The hydraulic cylinder can control the lifting and lowering of the pressing frame, and the lifting and lowering of the pressing frame can control the lifting and lowering adjustment of the upper pressure roller, thereby realizing the adjustment of the leveling pressure during the leveling process of the steel strip.
[0013] The present invention is further configured such that the protective cover has an installation groove, and the side of the pressing frame slides within the installation groove. This allows for better installation of the pressing frame and improves the cooperation effect between the upper and lower pressure rollers.
[0014] The present invention is further configured such that a limiting slide bar is provided on the side wall of the mounting groove, and a limiting slide groove is provided on the side wall of the clamping frame. The limiting slide bar slides within the limiting slide groove. When the clamping frame moves, the limiting slide bar moves within the limiting slide groove. The cooperation between the limiting slide bar and the limiting slide groove can improve the movement stability of the clamping frame, thereby improving the cooperation stability between the upper pressure roller and the lower pressure roller.
[0015] The present invention is further configured such that an induction heating element is provided at the front end of the clamping frame, wherein the induction heating element is an induction coil module, which generates eddy currents on the surface of the steel strip through a high-frequency induction coil, and quickly heats it to the target temperature. This can reduce the material hardness, reduce residual stress, improve the leveling accuracy and extend the equipment life.
