摘要
结合锻造工艺理论的现状和发展情况,对刘助柏教授提出的圆柱体镦粗新理论、锥形板镦粗新工艺进行了评述。认为该新理论能够反映大型锻件内部应力状态的实际情况,弥补了传统的镦粗理论的不足,是对自由锻造工艺理论的一个重要探索。
Regarding to the current and future development of the forging process theory, this paper has evaluated the new theory of the cylinder upsetting and the new process of the cone-shaped upsetting proposed by Prof. Liu Zhubai. The new theory can reflect the actual inner stress status of the heavy forgings and compensate the imperfection of the conventional upsetting theory, which makes a great contribution to the free forging process and theory.
