For example, it is manufactured through the following steps. That is, first, in a first step, as shown in FIG. 3A, in a state where the plate-shaped material 5 is held by the blank punch 6 and the draw pad 8, as shown in FIGS. Then, the die center 9 is moved to form the material 5 from a plate shape into a shallow drawn cup 5a. The bottom and the side of the die center 9 on the side pressing the material 5 are substantially perpendicular to each other.

る。[0004] In the manufacturing process of such an aluminum can, in order to suppress the occurrence of wrinkles in the cup in the above-mentioned redrawing, for example, by adjusting the cylinder pressure for applying a thrust to the holder 2, etc. The wrinkle pushing force is increased. In the bottom forming process, the pressure for pressing the mold is increased. Further, for example, as described in Japanese Patent Application No. Hei 7-88580, there is a method of forming a shallow drawing cup from a plate material and preforming the bottom of the cup so as not to cause wrinkles at the bottom.

拘束のない状態で成形されるために生じる。In recent years, there has been a demand for reducing the diameter of the lid in order to reduce the material cost of the lid. When the diameter of the lid is reduced in this manner, it is necessary to reduce the diameter of the bottom contact of the aluminum can from the viewpoint of ensuring stacking performance. However, when the bottom contact diameter of the aluminum can is reduced, for example, when performing bottom preforming by redrawing, there is a problem that wrinkles are easily generated in the bottom. As described above, when wrinkles occur during the bottom preforming, the wrinkles cannot be eliminated even when the bottom forming process is performed, and traces of the wrinkles remain on the product. This bottom wrinkle occurs because, for example, the material 5 is formed between the tip of the punch 3 and the radius portion of the die 4 without restriction by a mold or the like during redrawing.

Further, as described above, in the method of preforming the bottom of the cup, it is necessary to significantly change the structure of the cupping press, and the cost associated with the change becomes enormous.
