摘要： A method of producing seamless cans wherein a blank holder 2 is inserted in a metal cup 5 coated with an organic film 12, a punch 1 is advanced into a cavity 7 in a die 3 while pushing the bottom 5a of the metal cup onto the flat surface portion 3a of the die by the blank holder 2, so that the side wall 5b of the metal cup 5 is brought into intimate contact with the flat surface portion 3a of the die and with the working corner 3b having a small radius of curvature, thereby to reduce the thickness of the side wall 5b by bend-elongation. Moreover, the portion to be subjected to the necking is ironed at an ironing ratio of not smaller than 5% by the punch 1 in cooperation with the front end 3b.sub.1, of the working corner 3b, or by the front end 3b.sub.1, and an ironing portion of a short cylindrical portion in front thereof, or by the punch 1 in cooperation with the ironing portion 3g of the die 3 by advancing the side wall 5b slightly toward the inside in the cavity 7, thereby to obtain a seamless can 20 having a reduced thickness in the side wall 5b. This method makes it possible to control the thickness distribution in the side wall and, hence, to produce seamless cans having reduced thickness in the side wall permitting the organic film to be least whitened during the necking working.
摘要翻译：一种生产无缝罐的方法，其中将坯料夹持器2插入涂覆有机膜12的金属杯5中，冲压机1推进到模具3中的空腔7中，同时将金属杯的底部5a推到平面金属杯5的侧壁5b与模具的平面部3a紧密接触，并且具有小的曲率半径的工作角部3b，从而通过弯曲伸长来减小侧壁5b的厚度。此外，通过与作业拐角3b的前端3b1或前端3b1配合的冲头1以熨烫比为5％以上的部分进行颈缩的部分熨烫，以及熨烫通过使侧壁5b稍微朝向空腔7内的内侧前进，与冲头3的熨烫部3g配合，通过冲头1与冲头1配合，从而得到具有减小侧壁5b的厚度。这种方法使得可以控制侧壁的厚度分布，并且因此在侧壁中产生具有减小的厚度的无缝罐，从而允许有机膜在颈缩加工期间最少白化。

摘要： A method and a device for manufacturing a synthetic resin coated metal can body capable of drawing and ironing the synthetic resin coated metal can body with a large processing quantity without causing can body breakage. First and second ironings are conducted to the side wall of a redrawn can (20) formed by drawing a thermoplastic resin-coated aluminum sheet (1) on both surfaces by a first ironing die (14) and a second ironing die (15) in that order according to the pressing-in of a punch (11) with such processing quantities that sheet thickness reduction ratios from an original sheet thickness come within the rages of 35 to 55% and 60 to 75% respectively for manufacturing a metal can body. Since the coated layer of a thermoplastic resin acts on a metal body in a direction for preventing the metal body from being broken (ruptured), processing conditions for ironing are relieved, and even if an ironing with a high sheet thickness reduction ratio is performed, an ironing capable of maintaining quality is allowed without causing the can body breakage in a first step can (21) and a second step can (22).
摘要翻译：一种用于制造合成树脂涂覆的金属罐体的方法和装置，其能够以大的加工量拉伸和熨烫合成树脂涂覆的金属罐体，而不会导致罐体破损。第一和第二熨斗被引导到通过第一熨烫模具（14）和第二熨烫模具（15）在两个表面上拉伸热塑性树脂涂覆的铝片（1）而形成的再拉伸罐（20）的侧壁根据冲头（11）的按压顺序，其具有这样的处理量，即从原始板厚度的板厚减小率分别在制造金属罐体的35至55％和60至75％的范围内。由于热塑性树脂的涂层沿着防止金属体破裂（破裂）的方向作用在金属体上，所以减轻了熨烫的加工条件，即使进行了薄板厚度降低率的熨烫，允许在第一步骤罐（21）和第二步骤罐（22）中不会导致罐体断裂而能够保持质量的熨烫。

摘要： A method of drawing and ironing a resin film laminated metal sheet for forming a can body having a bottom portion, a can wall portion and a flange-forming portion by drawing the resin film laminated metal sheet obtained by laminating at least one surface of a metal sheet with an organic resin film, followed by ironing by using a punch and a plurality of dies neighboring each other. The can wall is effectively prevented from being broken by a decrease in the thickness of the can wall, and drawn and ironed cans are efficiently formed having a thickness which is decreased as designed.
