The Influence and Simulation of Crank Shaft Length over Upper Knife Holder Trace of Rolling-Cut Bilateral Shear

Abstract:

Rolling-cut bilateral shear is a sort of auxiliary equipment with arc upper blade performing pure rolling over flat lower one. The working principle are characterized as up-and-down movement of upper blade by crank shaft, after the rotation caused by the phase difference between two shafts, which makes upper blade rotate to adapt to steel shearing with different thickness. Through analysis the processing of rolling-cut bilateral shear and make the shearing mechanism simplify 8-linkage, and then the kinetics formula of shearing mechanism was established. The relationship of crank shaft length of rolling-cut bilateral shear in shearing process and movement trace of upper blade (shearing overlapping) was obtained as well as the change rule of length of linkage over upper blade, which provides the theoretical support for the design of rolling-cut bilateral shear.
