摘 要
在汽车更新换代的过程中,汽车覆盖件成形是整个汽车行业的重要组成部分,也是技术最密集、加工难度最大的部分。由于汽车覆盖件形状十分复杂,常用的工艺生产方式会引起零件回弹、拉裂现象,同时效率低下是现有的覆盖件的普遍问题。冲压是生产汽车覆盖件的主要工艺,合理的设计和安排冲压工艺的各道工序是保证覆盖件的主要工艺,合理的设计和安排冲压工艺的各道工序是保证覆盖件质量和精度的关键。本课题主要通过复杂汽车覆盖件成形过程分析,完成冲压成形工艺方案的设计,并对其进行验证。复杂覆盖件冲压成形过程是一个包含多种物理特征“非线性”变化的复杂过程。
为了更好的研究研究轿车覆盖件,并对其综合冲压工艺过程和攻击方法进行设计,本文开展了以下工作:
(1)首先通过对汽车覆盖件冲压工艺的现状及发展趋势进行了综述,结合了某一覆盖件产品,阐述了覆盖件冲压工艺的设计方法以及流程。
(2)在对产品进行结构特征和成形可能性分析的基础上,通过对零件冲压工序的逐步分析、工位排列及工序集中等设计,完成了该产品全流程的冲压工艺方案设计,提高了生产效率。
(3)结合了所研究的覆盖件产品特征及冲压成形特点,对冲压工艺设计的基本内容、合理标准以及工艺方法进行了阐述。
(4)对汽车覆盖件冲压工艺方案和工序的顺序进行了制定,通过工艺的设计使得汽车覆盖件的设计更加合理。
(5)着重研究了拉延模的计算、修边线的方向、冲孔工序的设计,从而完成汽车覆盖件冲压工艺的详细设计。

Abstract
In the process of automotive replacement,Automotive panel forming is an important part of the entire automotive industry,and it is also the most technologically intensive, the most difficult part of the process,Due to the complexity of the shape of the car cover, craft production methods commonly cause parts rebound, the phenomenon of crack,meanwhile,Inefficiency is a common problem in conventional cover.The main process is the production of automotive stamping parts covered,Rational design and arrangement of the various processes of stamping process is to ensure that the cover of the main process.And reasonable arrangements for stamping process design and each process is the key cover to ensure the quality and accuracy.The main topic of the forming process analysis through complex auto cover and Completion of the stamping process plan design and validate.Stamping complex process is a complex process that contains a variety of physical characteristics "nonlinear" change. order to better research studies car cover, and its consolidated stamping process design and attack methods, this paper carried out the following:
(1)First, through analyzing the present situation and development trend of stamping process of automobile panel are reviewed.With a covering parts, presents a design method of stamping process and process.
(2)Based on the structure feature and forming possibility analysis of product.Through the analysis of the stamping process gradually, the station arrangement and process design, completed the whole process of the stamping process for the design of the product.And it Improves production efficiency.
(3)Combined with the panel product features and forming characteristics,The basic content of stamping process design, reasonable standard and process methods are described.
(4)The stamping process plan and process of automobile covering the order is established, through process design makes the design of automobile panel is more reasonable.
(5)The design focuses on the calculation, drawing die trimming line direction,punching process, so as to complete the detailed design of stamping process of automobile panel.
