It is formed so that it can be fitted perfectly, and has an arcuate groove 16 around its side surface to prevent the inwardly curved peripheral edges 27 and 28 of the side surface of the can body from being crushed during molding. Diagonal grooves 17 are provided on both sides corresponding to the rotating dies 7, 7 so that the projecting edges 10, 10 can enter when the male mold is raised after molding.
17 are provided. Reference numeral 18 indicates a relief portion of the folded portion 22, and reference numeral 19 indicates a shank connected to a known press (not shown).
次に上記装置を用いて角缶を製造する場合によ
き説明する。 Next, a case in which square cans are manufactured using the above-mentioned apparatus will be explained.
先ず予め、第５図に示す如き薄金属板C1を別
の金型で打ち抜く。この金属板では各隅角の折込
部２２の周縁２３を切除すると共に折込部の尖端
部２４も切除する。 First, a thin metal plate C1 as shown in FIG. 5 is punched out using another die. In this metal plate, the periphery 23 of the folded portion 22 at each corner is cut out, and the pointed end 24 of the folded portion is also cut off.
次に第６図のC2に示す如く、上記打ち抜かれ
た金属板Ｃの各折込部２２に折込線２５と折曲線
２６を設け且つ折込線２５側より折曲線２６側を
やや打ち起すと同時に、各側面部２７，２８の周
縁２７′，２８′を上向きに弯曲させる。 Next, as shown in C 2 of FIG. 6, a folding line 25 and a folding line 26 are provided in each folding part 22 of the punched metal plate C, and the folding line 26 side is slightly raised from the folding line 25 side. , the peripheral edges 27', 28' of each side surface portion 27, 28 are curved upward.
而して、雌型の案内板側１２を取出口１５側よ

底板４に突き当る。 After the guide plate side 12 of the female mold is made considerably higher than the opening 15 side and the entire female mold is fixed diagonally, when the punched metal plate C 2 is placed on the guide plate 12, the metal The plate slides under its own weight and is stopped by the stopper 14, and is positioned above the fixed dies 6, 6 and the rotating dies 7, 7. Then, when the male die B is pressed in with a press, one of the two side surfaces 28, 28 of the metal plate is folded up with the fixed dies 6, 6, and then the other both side surfaces 27, 27 are folded up with the two rotating dies 7, which are vertically opposed to each other. ，
7, each folding part 22 is crimped to the side part, and it becomes a square can shape and enters between the die holders 5, 5, and the bottom of the male mold B is pushed into the bottom plate 4 through the bottom part 29 of the metal plate. Hit.
更に、実施例の如く凹所２内にスプリング３を
