dynaform某汽车结构件的冲压模具设计与成型模拟

摘要钣金件是一种广泛应用于汽车中的结构件，本课题针对某汽车钣金结构件设计一套冲压模具，首先设计汽车结构件冲压总体方案，使用 dynaform 软件进行模具冲压仿真，对整个制件成型过程进行冲压仿真分析，准确预测钣金件的成型过程、厚度变化、应力应变和金属流动情况，从而为模具设计提供最佳方案。使用 solidworks 软件分别设计凸模、凹模、定位装置、卸料装置和固定结构，完成模具结构设计。依照汽车结构件的形状、精度、大小、工艺要求以及 dynaform 软件钣金分析所得到的设计参数，按照相应的设计步骤，最终完成某汽车结构件冲压模具的全部设计。最后绘制总体方案图和部分零、部件工程图纸。68491

Title Stamping die design and forming simulation of the Automobile parts

Abstract

The sheet metal parts is widely used in automobiles, this topic researches on designing a stamping die for automobile sheet metal structure . First design the method of processing automobile structural components,using the DYNAFORM software to simulate and analyze the molding process, accurate prediction the forming process ,Thickness variation, strain and metal flow of sheet metal, so as to provide the best plan for die design.using the SolidWorks software to design the punch and die, positioning device,discharge device and fixed structure, completed the design of the die structure.according to automobile structure shape,size, precision, process requirements and The design parameters from DYNAFORM software for sheet metal analysis, in accordance with the relevant design process, finish all the design of the car parts stamping die. Finally draw overall plans and some of the engineering drawings.
