Abstract
PURPOSE: To make the closeness between outer and inner blades uniform and improve the cutting quality by providing the inner blades with a certain curvature as shown in Formula II.
CONSTITUTION: One contact point between an upper curved part of outer blade supporting frame 1 and one end part of outer blade 2 is made as a starting point and direct axis x passing the other contact point is drawn, and when a thin metal plate is curved in an arch shape, there occurs deformation on the parabolic line connecting distance A between both of the contact points and height of the apex H. Since inner blade 2 is pressurized in the y axis direction by spring 6 installed around driving rod 5, in order to adjust the pressure in the x axis direction so that it folows the natural curve when the thin metal plate is curved, and also considering the fact that the pressure of spring 6 is imposed only in the y axis direction, if the shape of inner blade 3 is made with a slight smaller curvature as shown in Formula II, uniform contact pressure is obtained at the main part of the blade and the cutting quality is improved.
