Optimization research of the shell nosing mould of long steel pipe

Shell nosing is applied to fabricate part based on the technology demand of the product. Through the simulation of the shell nosing of long steel pipe using DEFORM-2D, a few parameters of the mould (the transition arc R_1, the transition arc R_2 and the inside diameter of upper die Φ are designed in optimal condition. The results indicate that when the radius of transition arc R_1 is 130mm, the radius of transition arc R_2 is 100mm and the inside diameter Φ of upper die is 288mm, the optimized shell nosing can be achieved and applied in factory.
