Roll-cutting shear quality monitoring system and method based on laser and visual inspection

Abstract

The invention belongs to the technical field of metal material machining process control systems, and particularly relates to a roll-cutting shear quality monitoring system and method based on laser and visual inspection. The invention aims to improve the intelligent control level of the roll-cutting shear and improve the shearing quality of a medium plate. The system comprises a system monitoringupper computer, a system detection device, a system regulation and control execution device and a control system, a shear blade gap wedge-shaped adjusting mechanism is driven by a servo hydraulic cylinder, a servo valve is used for regulation and control, the adjustment of the shear blade gap is achieved, the shear blade gap wedge-shaped adjusting mechanism converts longitudinal linear motion ofthe hydraulic cylinder into horizontal transverse motion of a shear blade, the rigidity of the shear blade is guaranteed through a wedge-shaped block and a pressing mechanism, and the control over theshear blade gap of the roll-cutting shear is achieved.

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 ...

AI Technical Summary

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
