The fine blanking press supports huge impact load and high-speed stamping frequency in the work process, and the deformation of the molds and the precision of components are significantly influenced by the deformation and vibration of the press. The frame under impact load and stamping frequency, thus the frame structure is the key factor to ensure the reliable work. To make the virtual prototype of the 12000KN fine blanking press frame meet requirements in the best way, the concept design of the frame was built. And optimal interval of the frame stiffness and first order natural frequency were find according to finite element analysis, which can lay the foundation for the design of an ideal frame.
