Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to an automatic leveling machine. Background Art

[0002] Steel plate is a flat steel plate made by pouring molten steel and pressing it after cooling. It is rectangular and can be directly rolled or cut from a wide steel strip. Due to the development of process technology, the quality requirements for metal plates are also high. Therefore, in actual production, it is necessary to process defective metal plates to make the plates reach the required flatness without removing materials, or to process recycled steel plates. This is when a leveling machine is used.

[0003] For example, the utility model with application number 201921047260.9 discloses a steel plate leveling machine. The utility model is provided with a leveling mechanism, a placing table, a pressing plate, a first cylinder, a mounting plate, a second cylinder, a box body, an auxiliary roller and a rotating column, which can effectively ensure the leveling effect and accuracy, and can level steel plates of different thicknesses, while reducing the wear of the roller group and increasing its service life. During leveling, the steel plate is first placed on the top of the placing table, and then the first cylinder is started by an external controller, and the pressing plate is driven by the first cylinder. The pressing plate moves downward to perform the initial leveling of the steel plate, and then the initially leveled steel plate is pushed from the feed port into the box body, and then the second cylinder is started by an external controller, and the first mounting frame and the second mounting frame are driven by the second cylinder to move up and down. , which is used to adjust the gap between the upper and lower roller groups, so as to facilitate the leveling of steel plates of different thicknesses. After the adjustment, the motor is started by an external controller, and the motor drives the connecting column, and the connecting column drives the active roller to rotate. At the same time, the active pulley drives the driven pulley through the belt, and the driven pulley drives the driven roller to rotate, so as to perform secondary correction on it. After correction, it is discharged from the discharge port, and the feed port and the discharge port can be opened in different sizes according to the needs, which solves the problem that the existing leveling machine has poor leveling effect, and the leveling gap and the position of the upper roller are fixed. At the same time, different specifications of leveling machines are required to process steel plates of different thicknesses, which is not only time-consuming and labor-intensive, but also costly. Since the old leveling machine directly uses a roller group for leveling, this will increase the wear of the roller group, thereby reducing its service life.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of steel plate leveling machine uses a cylinder to adjust the spacing between rollers to accommodate steel plates of different thicknesses. Although it has good adaptability, there are no components on the rollers to limit the position of the steel plates. Problems such as positional offset may occur in the process of conveying and leveling the steel plates. The offset position may cause problems such as material jamming, blockage, and deformation of the steel plates.

[0006] Therefore, an automatic leveling machine is designed to optimize the above problems. Utility Model Content
