Abstract:Aiming at the problem of the in accurate calculation of the shear force due to blade passivation in flying shear equipment of continuous annealing unit, through fully considering the equipment and process characteristics of flying shear and analyzing the passivation law, the blade passivation model of flying shears was established. On this basis, a new concept of cutting edge passivation coefficients was put forward for the first time. According to the theory of oblique cutting, the shear force calculation model for the flying shear equipment of the unit was established, and the accurate expression of the actual shear force was realized. Then, the factors affecting the shear force of flying shear were analyzed, and ’’shear stress prediction and influence factor analysis about flying shear equipment of continuous annealing unit software’’ was programmed. It was applied in the production line of continuous annealing line, and could play a guiding role in the selection of motor power and blade hardness as well as the setting of process parameters for flying shear equipment.
