英国伯明翰 A H Cole 公司经过大约十年的研究,研制出一种串联式连续拉延模。这种拉延模能够在压力机的一个行程中完成五次拉延。虽然这只是一个实验性装置,但表演了用0.38毫米厚的电镀马口铁拉制φ25.4×127毫米、底部和璧部厚度与坯料厚度相同的容器。与人们比较熟悉的单次拉延和并连式连续拉延相比,串联式连续拉延模 After about ten years of research, A H Cole, Birmingham, UK, developed a tandem continuous drawing die. The drawing die is capable of drawing five draws in one stroke of the press. Although this was just an experimental device, it performed a container of φ25.4 x 127 mm with a 0.38 mm thick galvanized tinplate with the same thickness as the billet at the bottom and the billet. And people are more familiar with the single drawing and parallel continuous drawing compared to the series of continuous drawing die
