を特徴とする罐口円弧部の成形方法にある。[Means for Solving the Problems] The present invention has been made to solve the problems. That is, a part of the metal plate (3) having the laminate material (2) on the inner surface of the metal plate material (1) is formed from a flat state to a vertical rising part (5e) having a hole (5c), and then, In the method for forming a canister circular arc portion in which the vertical rising portion (5e) is formed in a small circular arc portion (5f) from the outer side to the lower side, a cone is formed on the flat portion (5a) of the metal plate (3). Forming the rising part (5b), this conical rising part (5b)
After forming the hole (5c) inside the vicinity of the connecting part (5d) of b) so that the side surface (5g) is vertical, the hole is formed vertically including the connecting part (5d) of the conical rising part (5b). Startup section (5
e), and the vertical rising portion (5e) is formed in a small circular arc portion (5f) from the outer side to the lower side and further inward.
［作用］ かかる本発明の成形方法によれば、円錐立ち上げ部
（5b）の連接部（5d）が垂直立ち上げ部（5e）内に含ま
れていて外側に変形しやすくなっているので、垂直立ち
上げ部（5e）を外側から下方へさらに内方へと成形する
際に、円弧部（5f）の形成が著しく容易となる。[Operation] According to the molding method of the present invention, since the connecting portion (5d) of the conical rising portion (5b) is included in the vertical rising portion (5e) and is easily deformed to the outside, When the vertical rising portion (5e) is formed from the outer side to the lower side and further inward, the arc portion (5f) is significantly facilitated to be formed.
また、円錐立ち上げ部（5b）の連接部（5d）近傍内側

なり、垂直立ち上げ部（5e）を成形する際に、この連接
部（5d）から小さく変形することができ、極めて小さな
円弧部を形成することができる。Since the hole (5c) is formed inside the conical rising part (5b) near the connecting part (5d), this deformable connecting part (5d) should be located above the vertical rising part (5e). Therefore, when the vertical rising portion (5e) is formed, the connecting portion (5d) can be slightly deformed, and an extremely small arc portion can be formed.

変形力が強く加わり、それによりラミネート材（２）を
損傷せずに成形できる。Furthermore, since the hole (5c) is formed in the conical rising portion (5b) having the laminating material (2) on the inner surface so that the side surface (5g) is vertical, the laminating material (2) is a metal plate material ( The hole (5c) can be formed while maintaining a state of being closely adhered to 1). And vertical launching part (5e)
Since the non-laminating side of the metal plate material (1) is higher in the state where the metal plate material (1) is formed, when the vertical rising part (5e) is deformed by the upper die (7), the metal plate material (1) is Since the laminating material side is high, a deforming force is strongly applied to the anti-laminating material side, whereby the laminating material (2) can be molded without damage.
［実施例］ 以下、本発明の一実施例を第１図〜第３図に基いて説

面に貼着されたラミネート材２とより構成されている。
まず、金属板３は平板状態から円筒状側壁部４と上壁部
５とカシメ部６との三部分が所定形状になるように形成
される。上壁部５は、第２図に示すように、平坦部5aの
中央部に円錐立ち上げ部5bが形成され、この円錐立ち上
げ部5bの平坦部5aとの連接部5d近傍内側に穴5cをその側
面5gが垂直になるように形成される。平坦部5aから円錐
立ち上げ部5bが形成されるので、その連接部5dが弱い部
分となっている。また、内面にラミネート材２を有する
円錐立ち上げ部5bに穴5cをその側面5gが垂直になるよう
に形成されるので、ラミネート材２が金属板素材１に良
好に密着した状態を保ったまま穴5cが形成される。The metal plate 3 for a mouthpiece is composed of a tin metal plate material 1 and a laminating material 2 attached to the inner surface thereof.
First, the metal plate 3 is formed in a flat plate state so that the cylindrical side wall portion 4, the upper wall portion 5, and the crimp portion 6 have three predetermined shapes. As shown in FIG. 2, in the upper wall portion 5, a conical rising portion 5b is formed in the central portion of the flat portion 5a. Is formed so that its side surface 5g is vertical. Since the conical rising part 5b is formed from the flat part 5a, the connecting part 5d is a weak part. Further, since the hole 5c is formed in the conical rising portion 5b having the laminating material 2 on the inner surface so that the side surface 5g becomes vertical, the laminating material 2 is kept in good contact with the metal plate material 1. Hole 5c is formed.
しかる後、円錐立ち上げ部5bの連接部5dを含んで垂直
立ち上げ部5eが第３図に示すように平坦部5aから形成さ
れる。連接部5dは垂直立ち上げ部5eの上部に位置するこ
とになる。Thereafter, the vertical rising portion 5e including the connecting portion 5d of the conical rising portion 5b is formed from the flat portion 5a as shown in FIG. The connecting portion 5d is located above the vertical rising portion 5e.
次いで、第３図に示すように円筒状側壁部４内に成形
用下型８を挿入して下型８上に平坦部5aを載置した状態
で、円弧状の成形用凹面を有する成形用上型７を降下さ
せて垂直立ち上げ部5eの上端を上型７の成形用凹面に当
接し、さらに上型７を降下させる。これにより、垂直立
ち上げ部5eは、成形用凹面に案内されて外側から下方へ
と変形し、さらに内方へと変形して小さな円弧部5fが第
１図に示すように形成される。Then, as shown in FIG. 3, the molding lower die 8 is inserted into the cylindrical side wall portion 4 and the flat portion 5a is placed on the lower die 8, and the molding die having an arcuate molding concave surface is formed. The upper die 7 is lowered to bring the upper end of the vertical rising portion 5e into contact with the molding concave surface of the upper die 7 and further lower the upper die 7. As a result, the vertical rising portion 5e is guided by the molding concave surface, deforms downward from the outside, and further deforms inward to form a small arc portion 5f as shown in FIG.
この際、円錐立ち上げ部5bの連接部5dが垂直立ち上げ
部5e内に含まれていて外側に変形しやすくなっているの
で、著しく容易に変形される。しかも、この変形しやす
い連接部5dが垂直立ち上げ部5eの上部に位置されている
ので、連接部5dから小さく変形され、極めて小さな円弧
部5fが形成される。At this time, since the connecting portion 5d of the conical rising portion 5b is included in the vertical rising portion 5e and is easily deformed outward, it is remarkably easily deformed. Moreover, since the deformable connecting portion 5d is located above the vertical rising portion 5e, the connecting portion 5d is slightly deformed to form an extremely small arc portion 5f.
上型７の成形用凹面で垂直立ち上げ部5eの変形を開始
する際に、金属板素材１の反ラミネート材側が高くなっ
ているので、反ラミネート材側に変形力が強く加わり、
これによりラミネート材２を損傷せずに成形することが
できる。When the vertical rising portion 5e starts to be deformed on the molding concave surface of the upper die 7, the anti-laminating material side of the metal plate material 1 is high, and therefore the anti-laminating material side is strongly deformed.
Thereby, the laminate material 2 can be molded without damage.
［発明の効果］ 本発明によれば、極めて小さな円弧部を著しく容易に
ラミネート材を損傷することない罐口円弧部の成形方法
を提供することができる。[Advantages of the Invention] According to the present invention, it is possible to provide a method for forming a mouth arc portion in which an extremely small arc portion does not damage the laminate material very easily.
