Study of the Knife-Gap Adjustment for Rolling-Cut Bilateral Shear

Abstract

The knife-gap accuracy of rolling-cut bilateral shear is one of the key factors influencing the cutting quality. This paper through the site of a high strength low alloy steel shear test, a linear regression equation for the relation between knife-gap and plate thickness is obtained and optimize by using MATLAB Toolbox, after optimization of the linear regression equation can be conveniently used, reduce knife-gap adjustment time, improve production efficiency, reduce shearing defects.

The Analysis of the Influence on Quality of Shearing Section

“…With the temperature changes, the stress properties of material also change. When the temperature inclined, the yield and resist-tension intensity increased and plasticity and tenacity descended [4]. The tenacity of material is especially sensitive to temperature.…”
