12000KN精冲压力机机身、主立板、下筋板对机身的，Abstract: For the 12000KN 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 press frame was designed, and its finite element analysis model was established. Using Hyperworks software research(research was done by hyperworks software about) the frame’s tilt amount effected by the thickness of side standing plate, main vertical board and under the rib when the eccentric load is imposed, and the main influencing factor is the thickness of main vertical board. It provides a theoretical basis(can lay the foundation) for fine blanking press frame design(the design of fine blanking press frame).

It’s crucial to get a fine blanking with good rigidity, large bearing capacity, load deflection resistance ability and light weight. To get high quality fine blanking parts, it is necessary to ensure that all parts of the fine blanking press with small work deformation, stress distribution and high guiding precision. As a more complex critical component, the structure of fine-blanking press frame is also the research object people first to carry out the structural analysis(去掉) [1]. 本文以12000KN精冲压力机机身为设计对象, 以机身受到偏心载荷时的倾斜量为试验指标，结合正交试验[2-3]研究了各板厚对机身倾斜量的影响规律和影响程度大小，为精冲压力机机身的设计优化ased on the 12000KN fine blanking press frame, using（去掉） the frame’s tilt amount under the eccentric load as（was） the test index, then the effect degree and rule of the thickness of some（去掉） plate on the tilt amount were studied combined with orthogonal experiment [2-3], It provides a theoretical basis for fine blanking press
