<p>The present invention relates to a method for determining parameters of a rolling shear mechanism according to technical requirements, including steps: (1) establishing a model in which Δ1 refers to the variable distance between the tip of the upper blade and its projection on the plane of the lower blade, Δ2 refers to the variable distance between the tip of the lower blade and its projection on the plane of the upper blade, the absolute value of Δ1 plus Δ2 is less than or equal to the permitted maximum range Δmax of the side clearances between the plate to be sheared and the upper or lower blades when the plate is in its minimum thickness δmin; (2) writing shear models of design variables for the six parameters to be determined by using the established model in optimized computing; (3) changing the shear models into objective models; (4) evaluating, according to the objective model, the rotary radius RD and RG of the lower and upper blades, the distance HO between the axles of the blades, the eccentric distance E between the axles of the blades, the clined angle ΥC and ΥK of the lower and upper blades, respectively.</p> |
