文档介绍：摘要
本文详细地阐述了厚板料冲小孔模具的设计及有限元模拟过程。首先简明叙述了现代国内外模具发展概况,通过有限元模拟分析模具可能出现的问题,然后重点设计了冲裁模具中相关部件,如凹凸模、模架设计以及压力机选择,并对冲压材料性能进行了分析。最后根据冲裁件的产品数量要求,以及结构要求,设计出来整套模具。整个设计过程都是用CAD、Pro/Engineering软件进行参数化设计,使整个模具设计过程简单明了。利用DEFORM软件进行有限元模拟分析,为模具设计和成型工艺的指定提供参照依据。
在设计过程中首先使用CAD软件设计成型零件以及非标零件,然后在Pro/Engineering软件中实现三维实体设计,最后导入DEFORM中,分析工件上选取点的应力、应变以及应变速率等相关因素,从而完成模具的整体设计以及有限元模拟,对直接指导生产有一定的意义。

ABSTRACT
The design of a die used for punching small holes on thick sheets and its finite element simulation were investigated in this paper. Elaborated the modern die & mould development situation concisely. First, by using finite analysis Microsoft to simulate the deformation processing for avoiding serious problems that may occur, then focusing on the calculation of the relevant parts in mould design, such as designing the die、bump, and formwork and choosing for punching machine , and analysis of material performance. Finally, according to the requirement of the structure and amounts of the product, we design the set of mold, and then carry out some related simulation analysis. We use CAD and Pro/Engineering software parameterization design in the process of whole designing, making the whole mold design process simple and clear to mend. Also, we use DEFORM software to provide reference basis of mould design and forming technology for the finite element analysis.
First, using CAD software design molding parts and non-standard parts in the design process, then, designing the 3D entity in Pro/Engineering software, finally, put the 3D entity into DEFORM to analyze the stress、strain and strain rate of selecting points. Thus, complete the overall design and finite element simulation and analysis, there must be have certain significance to direct production.
Key words thick sheet; blunt holes; parametric design; finite element simulation
