The die holder A57 is further crimped and protected by a die holder B58. Further, a rounded portion 61 is provided on the inside of one end surface of the die holder 57A, and a center line 62
It is divided into two parts (Figure 8). Die body 5
The squeeze surface 59 of No. 3 is the inner surface 6 of the die holder A57.
It is configured to be slightly smaller than 0.
以下に、上記の構成からなるプレス金型装置を
用いて板金１１を加工する場合について、図面を
参照しながら説明する。 Hereinafter, a case in which the sheet metal 11 is processed using the press die apparatus having the above configuration will be described with reference to the drawings.

５９と共同してしごき成形（２次加工）を行う。 In FIG. 7, the sheet metal 11 is
The die plate 16 and the punch plate 17 are pressed against each other while being sandwiched between the die plate 16 and the die holder A57 and the die holder B58. The compression spring 15 contracts, and the punch tool 12 advances to push the sheet metal 11 into the hollow parts of the die holder A57 and the die body 53, and the die holder A57
The sheet metal 11 is drawn (primary processing) in cooperation with the rounded portion 61 of the die body 53, and then ironed (secondary processing) is performed in cooperation with the inner circumferential surface 59 of the die body 53.

くいという効果を奏する。Effects of the Invention As described above, the press mold device of the present invention has a cylindrical shape with a hollow portion having the same size as the outside dimension after forming the sheet metal plus a predetermined clearance. A die holder made of a steel member with a rounded part on the inside, and a cylindrical shape having a hollow part of the same size as the outside dimension after forming the sheet metal, and this hollow part is concentric with the hollow part of the die holder. A processing member is provided with a die made of ceramic material arranged as shown in FIG. and the convex part of the processing member enters the die holder and the hollow part of the die, and after drawing and forming the sheet metal in cooperation with the rounded part of the die holder, it is ironed in cooperation with the inner circumferential surface of the die. During the drawing stage, which is the primary process, the die holder, which the sheet metal pressed by the punch tool comes into impact contact with, is made of steel, and a rounded part is provided at the part where the processing resistance is most severe. There is no risk of damage to the die holder, and since the die is made of non-metallic ceramic material during the ironing process, which is the secondary process, it has very little compatibility with sheet metal. This has the effect that burn-in is less likely to occur.
また、絞り成形およびしごき成形を一連の動作
で行うことができるという効果を奏するものであ
る。 Moreover, it has the effect that drawing forming and ironing forming can be performed in a series of operations.
