KNIFE CYLINDER, ROTARY DIE CUTTER, CUTTING TOOL MOUNTING BLOCK, AND KNIFE CYLINDER CUTTING TOOL MOUNTING BLOCK FIXING METHOD

摘要

A fixing hole (12) opened to the outer circumference face 11a of the knife cylinder (11) is formed. A magnetic-force generator (16) is fixed to the bottom face of the fixing hole (12) and a magnetic-force generator (34) is slidably arranged over the magnetic-force generator (16) . A sliding member (24) is inserted through a cylindrical face (14b) of a base (14) formed at the opening of the fixing hole (12) and is then placed inside the fixing hole (12) . North pole magnets (22a) and South pole magnets (22b) are embedded in respective semicircle regions on the contacting surface of the magnetic-force generators (16) and (34). The magnetic-force generator (34) is configured to rotate 180 degrees. Resilient force is generated by causing the magnets having the same polarity to each other face and project the flush portion (24a) from the fixing hole (12). Then, the slope face (48) of the penetrating hole (42) formed on the blade mount (40) is fitted and fixed to the space between the flush portion (24a) and the outer circumference face (11a).
