【摘要】：近年来,随着科学技术的发展,对各类零件的性能要求越来越高,在这种情况下,传统制造中用单一的材料构成的普通零件已难以满足各类近乎苛刻的使用条件。这使得异质材料零件成型的数字化微滴喷射控制技术研究成为先进制造技术领域的前沿课题之一。本文以基于光固化3DP印刷工艺的异质材料零件数字化设计制造展开探索研究。 1)分析了微滴喷射与UV光固化的研究与发展现状以及现在这两领域的热点问题,阐述了常规的光固化工艺的优缺点,为了优化工艺,将微滴喷射与UV光固化相结合,为异质材料零件成形提供了可能。 2)重点针对异质材料零件难以制造的问题,本文构建了基于光固化3DP印刷工艺的异质材料零件的成形系统装置。对异质材料零件成形系统的机械系统、控制系统、软件系统等展开研究,并对异质材料零件成形装置的控制系统进行重点研究。 3)基于搭建好的成形装置,本文对异质材料零件模型进行了大量的成形测试与数据分析,运用正交实验法分析影响UV固化图层品质的主要工艺参数,以成形精度和光泽度等为评价指标,通过试验对工艺参数进行优化。使用优化后的工艺参数对异质材料零件进行加工成形,实验结果表明成形系统各项指标和性能都己达到了设计目标。本文所设计搭建的异质材料零件的成形系统平台为多材料零件的集成化设计与快速制造奠定了基础。
[Abstract]:In recent years, with the development of science and technology, the performance requirements of all kinds of parts are becoming more and more high. In this case, it is difficult to meet all kinds of almost harsh operating conditions of ordinary parts made of single material in traditional manufacturing. This makes the research of digital micro-droplet injection control technology of heterogeneous material parts become one of the frontier topics in the field of advanced manufacturing technology. In this paper, the digital design and manufacture of heterogeneous material parts based on light curing 3DP printing process are studied. 1) the research and development status of micro droplet injection and UV curing and the hot issues in these two fields are analyzed. In this paper, the advantages and disadvantages of conventional light curing technology are described. In order to optimize the process, the combination of micro droplet injection and UV light curing provides the possibility for the forming of heterogeneous material parts. 2) focusing on the problem that it is difficult to manufacture heterogeneous material parts. In this paper, the forming system of heterogeneous material parts based on light curing 3DP printing process is constructed. The mechanical system, control system, software system and so on of the forming system of the heterogeneous material parts are studied, and the control system of the forming device of the heterogeneous material part is studied emphatically. In this paper, a large number of forming tests and data analysis are carried out on the heterogeneous material part model. The main process parameters affecting the quality of UV curing layer are analyzed by orthogonal experiment method. The forming accuracy and glossiness are taken as the evaluation indexes. The process parameters were optimized by experiment. The optimized process parameters are used to process the heterogeneous material parts. The experimental results show that the parameters and properties of the forming system have reached the design goal. The platform of forming system for heterogeneous parts in this paper lays a foundation for integrated design and rapid manufacturing of multi-material parts.
