Abstract

PURPOSE: To make projections on the surface of a hollow bar material in a very simple process by arranging a concave die on the hollow bar material, inserting the convex die and a receiving plate into the hollow part of the hollow bar material and forcing in a push plate between the convex die and the receiving plate.
CONSTITUTION: A convex die 8 having projections 5a in a hollow part 7' of a hollow bar material 7 and a receiving plate 9 are inserted in order to make projection on the surface 4 of a hollow raw material 3. A concave die 10 which makes a pair of the convex die 8 is arranged at a position corresponding to the convex die 8 on the outside of the hollow bar material 7. Then, after a holding tool 11 pushes the concave die 10 on the surface of the hollow bar material 7, a push plate 12 is forced in between the convex die 8 in the hollow part 7' and the receiving plate 9 by means of a hydraulic cylinder, etc., and the convex die 8 is pressed in the direction of the concave die 10.
