Abstract

PURPOSE: To provide a rolling device which produces shaft object products of specific shapes by bringing plural pieces of wedges, which are inclined at prescribed angles in the movable direction of a movable base body, and are disposed at successively increasing height sides, into pressure contact successively with the work.
CONSTITUTION: The motor of a driving base 2 is operated to revolve wedge rolls 10, 10 via a driving shaft 3, a universal joint 12 and a shaft 11. Thereby, the wedges 14n+1, 14n, 14n-1... of the rolls 10 are brought successively into contact with a blank pipe 5 which is the work, and the forming is completed by one turn of the rolls 10, 10. Hence, the time for forming is reduced considerably as compared to coventional methods of plural processes such as spinning, that is, wherein the work 5 and the rolls are revolved and further the rolls are moved in plural directions. The contact surface of the tool and the material forms the shape long in an axial direction, and the products of large working width having ≥5 ratios thereof are rolled with small working force, whereby productivity is improved.
