In the process in which the strip-shaped steel sheet 5 sequentially passes through the plurality of press dies 81 to 84 in the deep drawing zone A, the drawing process of a desired shape progresses, and the final stage press dies 84 allow the taper pipe portion 9 to be formed. A small-diameter pipe portion 10 extending continuously in the pipe axis direction is formed integrally with the small-diameter hole of the taper pipe portion 9 to deep-draw the caulking cap 3 formed in a substantially funnel shape. Since the deep drawing wrinkles 11 are generated on the caulking cap 3 due to the deep drawing formation, particularly on the inner surface of the tapered tube portion 9, the occurrence of the deep drawing wrinkles 11 causes the above problems.

Therefore, in this embodiment, when the caulking cap 3 deep-drawn in the deep-drawing zone A is moved to the adjacent coining zone B, the lower surface of the caulking cap 3 is dealt with in the coining zone B. As shown in FIG. 2, the inner and outer surfaces of the taper pipe portion 9 of the caulking cap 3 are compressed and deep-drawn to extend wrinkles by the positioned die 8C and the punch 8D corresponding to the upper surface of the caulking cap 3. Coining is performed to make the surface smooth. At that time, it is extremely important that no force is applied to the small diameter pipe portion 10 and only the tapered pipe portion 9 is coined.
