The invention provides a billet shearing device based on image sensing and a shearing method thereof. The method comprises the following steps: setting a coordinate system by two CCD image sensors, an image processing module, an image identification module and a drive module; performing image acquisition in real time; extracting a billet contour line, identifying a head part and a tail part of the billet; determining an optimum shearing lines at the head part and the tail part of the billet, obtaining the distance between the endpoint of the billet head part to be sheared and a shearing edge of a shearing machine, and controlling the shearing time of the shearing machine. In the invention, by adopting image acquisition, image processing and identification calculation in the above steps, the optimum shearing lines at the head part and at the tail part of the billet can be finally identified; and operation of a servo mechanism of the shearing machine can be accurately controlled according to the coordinate information of the optimum shearing lines, thus obtaining the best energy and material conservation effect for shearing the billet on a hot rolling production line.
Description
technical field [0001] The invention relates to a shearing device and a shearing method thereof in the technical field of mechanical equipment, in particular to a billet shearing device and a shearing method based on image sensing. Background technique [0002] The shearing of hot continuous rolling in steel mills is an important link in the continuous rolling process. The purpose is to cut off the curved edges that appear at the head and tail of the billet, so that the overall billet presents an approximately rectangular strip. How to achieve shear optimization is directly related to the technical issues of saving materials, energy and improving the economic benefits of enterprises. Specifically, it is necessary to solve the optimal shearing problem of the billet head and tail on the hot rolling machine. [0003] After searching the existing technical documents, it was found that the paper "Design and Realization of the Optimal Cutting Algorithm for Plates" by Tan Hansong ...
