摘要： PROBLEM TO BE SOLVED: To perform a drawing work at high productivity without generating cracks in a shoulder part or the like of a formed product and while suppressing the damage of a forming die even in the case of a blind cylindrical body which requires strength.
SOLUTION: After preliminarily drawing a high strength steel sheet into a blind cylindrical shape which approximates a desired shape, a plurality of preliminarily drawn goods are superimposed and drawn into the desired shape. Because the load to the die is remarkably reduced as compared with the case that the cylindrical body is formed from a thick plate by one drawing work, by adopting the preliminary drawing of the steel sheet, the maintenance of the die is reduced. Furthermore, a thick high-strength cylindrical body without cracks is manufactured simply and stably.

摘要翻译：要解决的问题：为了以高生产率进行拉拔加工，不会在成形品的肩部等产生裂纹，并且即使在要求的盲筒的情况下也能抑制成形模的损伤强度。解决方案：在将高强度钢板预先拉伸成近似所需形状的盲筒形状之后，将多个预先拉伸的物品叠加并拉伸成所需的形状。与通过一次拉伸加工由厚板形成圆筒体的情况相比，由于对模具的负荷明显降低，所以通过采用钢板的预备拉伸，能够降低模具的维护。此外，简单且稳定地制造无裂纹的厚的高强度圆筒体。版权所有（C）2010，JPO＆INPIT
