APPARATUS FOR FABRICATING CAGE OF NEEDLE ROLLER

摘要

PURPOSE: An apparatus for fabricating a cage of a needle roller is provided to improve productivity and quality of the cage of the needle roller by constantly forming an outer diameter of the cage without forming a tolerance. CONSTITUTION: A cage fabricating apparatus includes a rotary mold(20) gripped by a rotary chuck(2). The rotary mold(20) is provided to form an external appearance of the cage. The rotary mold(20) is formed at a lateral center portion thereof with a hole(21) into which a cylindrical workpiece(30) is inserted. A mounting recess section(22) is formed at an inner peripheral surface of the rotary mold(20) so as to mount the cylindrical workpiece(20) therein. A slot section(23) having a shape corresponding to a shape of an outer peripheral surface of a roller mold(10) is formed below the mounting recess section(22).
