Title:
A METHOD FOR DETERMINING PARAMETERS OF A ROLLING SHEAR MECHANISM ACCORDING TO TECHNICAL REQUIREMENTS
Document Type and Number:
WIPO Patent Application WO/2000/040361
Kind Code:
A1
Abstract:
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 $g(D)1 refers to the variable distance between the tip of the upper blade and its projection on the plane of the lower blade, $g(D)2 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 $g(D)1 plus $g(D)2 is less than or equal to the permitted maximum range $g(D)¿max? of the side clearances between the plate to be sheared and the upper or lower blades when the plate is in its minimum thickness $g(d)¿min?; (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 R¿D? and R¿G? of the lower and upper blades, the distance H¿O? between the axles of the blades, the eccentric distance E between the axles of the blades, the clined angle $g(U)¿C? and $g(U)¿K? of the lower and upper blades, respectively.
