Claims

[Scope of utility model registration request]

Of the press dies that form the workpiece through at least two press operations, each of which involves drawing, the press die that performs the first press operation includes a die that draws the workpiece in cooperation with a punch forming a lower mold. In preparation for the upper die, a positioning groove is cut out at the end of the workpiece in cooperation with teeth formed on the punch after the workpiece is drawn by cooperation with the punch and the die. A press mold characterized in that a sectional die is provided on the upper mold, and the positioning groove is used for positioning a workpiece during a second step of pressing work.
