PURPOSE: To provide a cutting device for a liner plate which can obliquely cut the liner plate in a short time, and cut a chip into plural pieces at the same time as the cutting of the liner plate.
CONSTITUTION: A liner plate cutting device is composed of a plate-shaped upper edge 5 vertically fixed to the cutter attaching saddle 7 of a press ram 6, a liner plate fixing base 9 provided on the lower part of the press ram 6, and a pair of plate-shaped lower edges 11 vertically fixed on the liner plate fixing base 9 at an interval being equal to the thickness of the upper edge 5. At least the edge tip of the lower edge 11 is formed in a wave form so as to coincide with a wave plate having the circumference flange of a liner plate 1, and plural number of projections to cut a chip into plural pieces at the same time as the cutting of the liner plate 1 are formed on the upper edge 5 at fixed intervals.
