发明名称 Cutting tool
摘要 A cutting tool, particularly for steel sheet billets, having a cutting blade fastened to a blade holder and a pressure cushion which is arranged on sides of the blade holder and, when the cutting blade penetrates into the material to be punched, is pressed onto the latter in the area of the useful punched part. During the passage of the cutting blade, a high-quality edge of the useful punched part is largely kept free of an interfering burr and elevation formation by the pressure cushion material being displaced radially outward during the punching stroke, such that the cutting blade is acted upon by pressure in the lateral direction under an increasing elastic deflection of the cutting blade edge.
