The lower blade 5 has a height such that it is flush with the conveying direction of the steel plate W.
And a work-up plate 7 which is pushed up by a spring 6 so as to always keep the same height as the conveying surface of the steel plate W so as to be in contact with the lower blade 5 and to the upper side thereof.
Is provided.

An upper blade 11 for cutting the steel plate W in cooperation with the blade 5 is provided, and the upper die 1 is provided via a toggle mechanism (not shown) or the like.
It is configured to move up and down integrally with 0.

る。As described above, according to the present invention, since the upper blade is attached to the upper side of the fixed lower blade in the workpiece conveying direction so as to be movable up and down, the next steel plate which has been pushed down by the upper blade. Since the burr can be directed upward on the front edge of the, when the steel plate is sent out for the next cutting, even if the front edge slides on the belt that continues to move, this burr does not damage the belt. Can be used for a long period of time, and at the same time, the deformation rate of the product caused by the adhesion of the scraped belt material can be greatly reduced.
