Abstract

PURPOSE:To form a titled shaft, etc. of high squareness and high strength even at the center of the surface of a metallic material by tearing up a projecting stripe made by die pressing on the surface of the metallic material and forming it by compression. CONSTITUTION:A slightly thick material, for instance a steel plate 1, is press- worked with a die 10 for die pressing to form a projecting stripe 2 on the surface of the plate 1. Next, this is torn up with a die 13 for tearing to form a projection band 3. A cylindrical shaft 4 is formed in a body with the plate 1 by placing the projection 3 in a press die and forming by compression. Besides forming the projecting stripe 2 near the end face of the metallic material 1 as mentioned above, the shaft, etc. can be formed at the center by forming the projecting stripe 2 at the center of the metallic material 1 and tearing up from its one side.
