Analysis of resistant-bias loading of 12,000KN fine-blanking press frame

摘要

For the 12,000KN fine-blanking machine's complexity, instantaneous, heavy stress conditions and fine-blanking die's high-precision, which puts forward a high stiffness requirement of the equipment, the structure of fine-blanking press frame was designed, and its finite element analysis model was established. Combined with variable-control method, research was done by Hyper works software about the frame's tilt amount affected by the thickness of side standing plate, main vertical board and under the ribs when the eccentric load is imposed. It can lay the foundation for the design of fine-blanking press frame.
