在有限元数值模拟基础上,根据模拟所得的最优型砧工艺参数,利用线切割技术加工一对新型复合曲面型砧。采用铅试件代替在高温状态下的钢,以KD法为基础,在1 000 k N液压材料实验机上进行有效锻合区域的实验验证。结果表明,有效锻合区域的有限元计算结果与实验结果基本吻合,证明了M型砧的优越性。 Based on the finite element numerical simulation, a pair of new composite curved anvils were manufactured by using the wire cutting technology according to the simulated optimum anvils process parameters. A lead specimen was used to replace the steel at high temperature. The KD method was used to test the effective forging area on a 1 000 k N hydraulic material testing machine. The results show that the calculated results of the effective forging region are in good agreement with the experimental results, which proves the superiority of M-type anvil.
