PURPOSE:To effectively absorb a shock caused when the end of a setting rod is adapted to a positioning stopper, by interposing a cam operation deceleration control mechanism between the moving cylinder of a movable base, arranged with the setting rod of cut length, and a feed discharge control valve. CONSTITUTION:A cutter is operated in such a manner that a movable base 26 is moved along a guide rail 35 by operation of an oil hydraulic cylinder 6 and the end of a cut length setting rod 25 arranged on the movable base 26 is adapted to a positioning stopper 36 provided in the prescribed position of a machine frame 7 then the end position of a cut material M is limited to decide its cut length. In this case, a cam block 38, having a deceleration operating cam 39 and pusher forwarding cam 40, is provided in one side of a movable block 29 movably fitted to the above described rod 25, simultaneously a cam operation deceleration control mechanism 41 is provided in the side of a moving path of the movable base 26. Then the cutter is constituted such that a built-in open-close valve for pressure oil feed-discharge control in said mechanism 41 is controlled by the cam 39 through a cam roller 48. |
