Abstract

PURPOSE:To permit a material to be shear-cut efficiently corrsponding to the thickness of the material to be shear-cut and the shear-cut resistance by adjusting the feed pitch so that the shear load value becomes smaller than the permissible load value of a shear, in shear-cutting of a thick material by using a rollng cur shear. CONSTITUTION:In the related chart regarding the feeding pitch f and the max. shear load Fs, the generated max. shear load Fs max. reduces by reducing the feed pitch of the material to be cut in relation to a rolling cut shear. Therefore, shear-cut of the material to be cut which has a large thickness of plate and a large shear is enabled by varying the feed pitch f within the range where the max. shear load generated in shear-cut becomes smaller than the permissible shear load of the shear-cut machine system.
