Abstract

PURPOSE:To prevent a punch and a die from shifting in center in a C type frame press machine by mounting bolster, which has the fitted die, on a head in a surface with specific curvature, and by sliding a rod installed on the bolster to the rod guide of a frame. CONSTITUTION:In a C frame press machine, work center lines (a) rotates around a center Q of rotation by an extent (theta) of inclination like an (a'), and a punch P and a die D shift in center to cause die galling. To prevent it, a cylindrical bolster V which has nearly the same curvature with a cylindrial head B with curvature which nearly has the center Q of curvature as the center of curvature is placed on the head B, and a rod L fixed to the bolster V slides on a rod guide G provided to a frame F. Even if the frame F opens in the front during work to shfit the center of the work from the (a) to the (a'), the bolster V also rotates around the Q, so the punch P and die D never shift in center.
