A quality monitoring system and method for rolling shears based on laser and vision detection

Abstract

The invention belongs to the technical field of metal material processing process control systems, and in particular relates to a rolling shear quality monitoring system and method based on laser and visual detection. The purpose of the invention is to improve the intelligent control level of rolling shears and improve the shearing quality of medium and thick plates. The present invention includes a system monitoring host computer, a system detection device, a system regulation and execution device, and a control system. The cutting edge clearance wedge-shaped adjustment mechanism of the present invention is driven by a servo hydraulic cylinder and regulated by a servo valve to realize the adjustment of the cutting edge clearance. The shear blade clearance wedge-shaped adjustment mechanism converts the longitudinal linear motion of the hydraulic cylinder into the horizontal and lateral motion of the shear blade, ensures the stiffness of the shear blade through the wedge block and the pressing mechanism, and realizes the control of the shear blade clearance of the rolling shear.

Description

technical field [0001] The invention belongs to the technical field of metal material processing process control systems, and in particular relates to a rolling shear quality monitoring system and method based on laser and visual detection. Background technique [0002] The shearing machine is an important core equipment on the medium and heavy plate finishing line. With the continuous increase of the thickness of the steel plate and the continuous improvement of the strength of the steel plate, the traditional shearing technology restricts the improvement of the cutting dimension accuracy and section quality of the medium and heavy plate. Compared with the general oblique blade cutting technology, the rolling shear technology has the advantages of good cutting quality, large cutting thickness, less scratch and wear of the cutting blade, straight cutting steel plate, and high cutting efficiency. Therefore, it is widely used in the medium and thick plate finishing line. The ...

Problems solved by technology

[0003] However, there are currently existing problems: in the subsequent finishing process of the medium and thick plate, it is necessary to check the straightness of the steel plate after shearing, the accuracy of the cut-to-length, and the tearing degree of the fracture. The traditional method is to rely on meter ruler detection and Manual visual judgment, detection accuracy and evaluation standards are heavily dependent on the responsibility and quality of workers, which is not only time-consuming and laborious, but also cannot achieve comprehensive, real-time, accurate and traceable records and evaluations
