なう。(Example) Next, a method for forming a shaft portion on a plate material according to the present invention will be explained using the drawings. FIG. 1 shows the steps of the first invention. First, a first tool 2 having a flat tip and a shape that tapers out from the tip is pressed against the plate material 1 from its negative side to form a hole 3 on one side and a protrusion 4 on the other side. First thing to do
Then, the plate material l that has gone through this first step is
A second tool 5 having a diamond-shaped tip and a shaft portion at its base having a diameter larger than that of the protrusion 4 of the plate material 1 is pressed to cause the protrusion 4 to further protrude and to enlarge the hole 3. A second step of forming a shoulder 6 in the hole 3 is performed, and then the first tool 2 is again pressed against the absorbent material l that has undergone this second step to give the protrusion 4 a height. Perform the third step of adding.
