Optimization of fine blanking machine's frame based on finite element analysis

For the fine blanking machine's complexity, instantaneous, heavy stress conditions and fine-blanking die's high-precision, which put forward a high stiffness requirement of the equipment, the structure of fine-blanking machine's frame was designed, and its finite element analysis model was established, then based on the result of the fine blanking machine's entablature, crutch and lower separator, a modified scheme of frame structure was put forward and further simulation was carried out to get the best scheme and improve the structure of fine blanking machine's frame. After the modification, both the stiffness and the strength met the requirements of frame structure, and finally the most optimized frame structure of fine blanking machine was drawn.
