A shearing machine for shearing a plate workpiece includes a frame; a ram having an upper cutting blade and being mounted on the frame in a vertically movable manner; a worktable being fixedly mounted on the frame and having a lower cutting blade to define an opening between the upper cutting blade and the lower cutting blade so that the plate workpiece to be sheared may be fed from the front side of the upper blades into the opening with a portion of the plate workpiece extending to the rear side of the opening; a conveyor being mounted on the frame for supporting the portion of the plate workpiece and for conveying the sheared portion of the plate workpiece to the rear side of the shearing machine, the conveyor being vertically movable in response to the vertical movement of the ram; and a drive shaft means having an eccentric member for driving both the ram and the conveyor reciprocalby up and down so that the conveyor descends before, or simultaneously with, the actual cutting into the workpiece by the upper cutting blade. The machine includes a cost-saving adjustable restraint, and a shiftable sheared product stacking mechanism.
