冲压模具毕业设计(论文) 摘 要 随着科学技术的发展，对压铸件产品的安全性和造型美观的要求不断提高。根据使用的不同，对零件的质量评价有所不同。如何生产出高质量的零件，对节约材料、能源和提高经济效益都有很大的意义。 分析了灯罩这种形状复杂、壁薄零件的结构特点。针对压铸中易形成裂纹、拉伸不足等缺陷的工艺特性，在根据理论分析的要求和数据的基础上运用Sol- idworks软件进行三维实体造型，并对未知的尺寸进行规定。然后利用这个三维实体计算零件的质量，在Solidworks软件中根据零件的质量来设计出的预定厚度的圆形坯料板材直径。根据所得的直径来确定原始坯料的一些尺寸，为后续的设计和研究提供一定的依据。同时利用Solidworks软件或其它三维软件对冲压模型可行性进行分析和设计，利用软件进行灯罩成型模的相关模具设计。 通过运用Solidworks软件，同时结合逆向造型的方法来设计相对应的模具，为了实现零件的成型，本人利用Solidworks软件设计四副模具，分别设计落料模、液压模、翻边模和卷边模，使原材坯料经过以上四副模具的加工来得到所要求的零件。 研究成果是得到四副模具三维模型和相对应的二维CAD图尺寸图。结论是得到所设计的零件的四副模具的相关数据，如果在实际生产中，可能运用的话，再添加其它相关的数据，可以成批生产。最后，对本次的模具设计进行总结。 关键词：落料； 液压； 翻边； 卷边 Abstract With the development of science and technology, Die-casting products for safety and aesthetic shapes rising. According to different use, Evaluation of the quality of parts are different. How to produce high-quality parts, to save materials, energy and increase economic efficiency has great significance. Analysis of the complexity of the shade of such a shape, thin-walled parts of the structural characteristics. Easy for die-casting in the formation of cracks, lack of defects in the tensile properties of the process, and in accordance with the requirements of theoretical analysis and data based on the use of Solidworks 3D solid modeling software, and the provisions of unknown size. Then calculated using the three-dimensional entities, the quality of parts, in accordance with Solidworks software to design parts of the quality of the target plate thickness the diameter of the circular blank. According to the original blank diameter to determine the number of dimensions for the design and follow-up to provide a basis for research. At the same time, the use of Solidworks software or other three-dimensional software model of the stamping feasibility analysis and design, use of software related to shade Mold mold design. Through the use of Solidworks software, combined with the method of reverse modeling of the corresponding mold design, molding parts i
