Abstract
PURPOSE: To produce shear drum driving torque for providing stable shearing force by presuming and calculating the shearing torque produced in the shearing.
CONSTITUTION: Shear blade speed detected by a tachometer 7 connected to a shear motor 6 and shear angle detected by an angle detector 8 are applied to a shear blade position calculation controller 15. On the other hand, a tachometer 9 and pulse generator 10 connected to a roll 3 measures workpiece speed and workpiece length. These outputs are applied to a calculation controller 13 for calculating shear start timing and shear acceleration. When arrival of a workpiece 5 is here detected by a material detector 4, the calculation controller 13 calculates necessary shear acceleration and timing to give them to a speed controller 12 for the shear motor 6 and start drive of a drum 1 through a current controller 11 for the shear motor 6 for providing stable shearing force.
