Abstract:
To provide a stopper of a cutting device capable of high-speed end material processing, in the end material processing of the cutting device for cutting a long size raw material of the definite length in a predetermined dimension.SOLUTION: When a billet 121 is sheared by the prescribed number, a piston 622 moves to an upper end position, and a stopper 67 retreats to the upper end position. A retreat stroke S3 of the stopper 67 (set in 20 millimeter in a stopper device 6 of the embodiment of the present invention) is set larger than a maximum height S1 in the vertical direction of a contact surface 674. Thus, the upper side of an outer peripheral part of an end material 122 is positioned on the lower side than a left end surface 673 of the stopper 67. Next, a succeeding rod material 12 is sent out in the right direction by operating an unillustrated rod material feed mechanism, and the end material 122 is sent out by the tip of the succeeding rod material 12. When continuously operating the unillustrated rod material feed mechanism thereafter, the end material 122 is pushed out by the tip of the succeeding rod material 12, and is discharged to an unillustrated recovery chute.SELECTED DRAWING: Figure 3
