锥形盒件拉深成形有限元分析及工艺正交优化

摘要随着我国汽车、飞机等工艺的发展,对金属板料成形的研究变得越来越重要, 对板料成形过程分析的需求日益迫切。目前,对于很多简单形件的拉深已有大量研究。
本课题选取了锥形盒件作为研究对象,对锥形盒件的拉深过程进行研究,通过PRO/E建立锥形盒件有限元模型,利用Dynaform对锥形盒件的拉深过程进行有限元仿真分析,探究了不同盒件锥度、模具参数、板厚、压边力等因素对此过程的影响,并利用正交优化的方法寻找较合理的参数组合,为生产提供帮助。8774

TitleFinite Element Analysis and Orthogonal Optimization of Deep Drawing of Taper Square Cups
Abstract
With the developing of cars and airplanes in our country, deep drawing from metal blanks has e increasingly important, and the analysis of blank forming has e increasingly urgent. Plenty of studies have been done in some kinds of simple cups.
The deep drawing process of the taper square cups is selected as the object of study. Firstly, the finite element model is established by PRO/, the deep drawing process is analyzed by finite element simulation with Dynaform. After that, different box tapers, mold parameters, blank thickness and the blank holder force in this process are explored. After all, a more bination of parameters is found by orthogonal method,which provides assistance for the production.

现阶段对某些形件拉深的研究已经有了较成熟的结论,比如圆筒形件、方形盒件,其模具制造参数在很多冲压模具设计手册上已经有了明确的结论。但是对锥形盒件这类兼备圆锥形件及方形盒件特点的特殊形件的拉深研究至今仍没有比较成熟的结论,基于锥形盒件在工业生产中频繁的使用率,本课题选择了对锥形盒件的拉深过程进行有限元仿真,探讨了锥形盒件拉深过程中的各因
