Abstract
PURPOSE: To reduce a main crank driving motor in capacity by using a speed regulating rod controlled to keep matching a speed of a steel billet with a parallel sliding speed of a pendulum shear just before a start of shearing.
CONSTITUTION: A speed regulating rod 13 is driven by a speed regulating motor 22, to which input data is sent from a steel billet thickness setter 14 and a steel billet sliding speed detector 29. A length of the speed regulating rod is converted into a main crank angle by a rod length and angle coverter 17. The result is put into a positioning unit 18 to set it in place by a feedback of the positioning detector 20. Matching of a steel billet sliding speed with a shear parallel sliding speed is continued just before a start of shearing. At a timing of the shearing start a lutch memory 15 is on to finish the speed matching control.
