Abstract

PURPOSE:To prevent a sheared work from rapidly dropping down onto a table, in an up cut shear, by following up a rise of the sheared work, lifted in accordance with a rise of a lower tool, and lifting the rear side table of the shearing machine. CONSTITUTION:A lift amount H1 of a lower tool 5, when a work 1 is sheared by the tool 5, is detected by a sensor 8, and this lift amount H1 is fed to a synchronization controller 10 through a lower tool position detector 9. In this way, on the basis of this lift amount H1, a rear surface table 3 is lifted by a rear table elevation power unit 11, and its lift amount H2 is detected by a sensor 12 and returned to the synchronization controller 10 then feedback control is performed. The lower tool 5 of a shearing machine is lifted, when the work 1 is sheared, the rear surface table 3 is lifted synchronously with the lift of the work 1.
