Abstract
Design of the seamless steel tubes blanking mould was introduced in this paper. On the basis of investigation for the blanking mould industry domestic and international developments in recent years, analysize the structure blanking form, the mechanical properties of steel pipe and the equipment of blanking and the tool of steel pipes cut-off. For analysis in the contraction issue in blanking the pipe and the work process and the principle of blanking mould, to focus on design calculations of the seamless steel tubes blanking design process. Introduction of the dual-core cutting punching of the seamless steel tubes for blanking, to achieve high-quality, efficient blanking. Finally, an introduction on the choice of material and heat treatment, the life of failure and design features in blanking mould design, was useful for understanding the design of the blanking mould.
