| Abstract: | In order to study the effects of technological parameters on the boss forming, the process plans are designed for the aviation connector according to its structural characteristics. A blanking and punching compound die is designed to complete the stamping process at the same time. The press forging of boss is simulated by using software of FEM, and optimization of press forging parameters for boss forming is obtained by using orthogonal method. The results show that the order of parameters that influence boss forming is as follows: the punch height, width, friction coefficient, length; when punch size is 5.5 mm×2.5 mm×1.2 mm, the friction coefficient 0.2, the boss forms with good results. |
