【摘要】：铝型材氧化电泳的过程直接影响到铝型材的表面质量、使用寿命及外观效果。表面处理是铝型材生产过程的最后一个环节,是最关键的一步,其过程复杂,受许多参数的影响。铝型材氧化电泳的质量不仅受脱脂、碱蚀、中和等表面前处理、阳极氧化、电泳涂漆、封孔等氧化电泳本身各工序的影响,铝合金铸锭质量、挤压质量等前面的生产工序也对氧化电泳的质量产生很大的影响。 本文运用现场调研、生产过程分析、文献研究等方法对HJ公司铝型材氧化电泳生产过程的诸多因素进行了研究。通过理论分析和现场生产相结合的方式,来确定生产过程的最佳工艺参数,找出影响氧化电泳铝型材产品质量不合格的主要因素,并提出了解决方法。 本文通过查阅大量相关文献,掌握了国内外质量管理及改进理论,通过对铝型材氧化电泳生产过程进行梳理和分析,进一步明确了关键流程和关键控制点,确定对产品质量产生主要影响的工序。通过对HJ公司氧化电泳车间的质量现状的调查分析,提出了HJ公司生产过程中存在的具体问题,并对生产过程中出现的质量问题进行分析总结,最后为HJ公司生产过程提供相应的质量改进方案。 本文的研究结果不仅为HJ公司氧化电泳车间进行质量改进提出了实施对策和解决方法,提高了HJ公司铝型材氧化电泳质量。同时,其他中小型企业进行质量改进也可以借鉴HJ公司的方法和经验。
[Abstract]:The process of aluminum profile oxidation electrophoresis directly affects the surface quality, service life and appearance effect of aluminum profile. Surface treatment is the last step and the most important step in aluminum profile production. The process is complex and affected by many parameters. The quality of aluminum profile oxidation electrophoresis is not only affected by the processes of degreasing, alkali etching, neutralization and surface pretreatment, anodic oxidation, electrophoretic painting, sealing hole, etc., the quality of aluminum alloy ingot, Extrusion quality and other previous production procedures also have a great impact on the quality of oxidative electrophoresis. In this paper, many factors in the production process of HJ aluminum profile by oxidative electrophoresis were studied by means of field investigation, production process analysis and literature study. Through the combination of theoretical analysis and field production, the optimum technological parameters of the production process are determined, the main factors affecting the quality of oxidized electrophoretic aluminum profiles are found out, and the solutions are put forward. Through consulting a large number of relevant documents, mastering the quality management and improvement theory at home and abroad, combing and analyzing the production process of aluminum profile oxidation electrophoresis, the key process and key control points are further clarified. Identify processes that have a major impact on product quality. Based on the investigation and analysis of the quality situation of the oxidation electrophoretic workshop of HJ Company, the concrete problems existing in the production process of HJ Company are put forward, and the quality problems in the production process are analyzed and summarized. Finally, it provides the corresponding quality improvement plan for HJ production process. The results of this paper not only put forward the countermeasures and solutions for improving the quality of HJ oxidation electrophoretic workshop, but also improve the quality of HJ aluminum profile oxidation electrophoresis. At the same time, other small and medium enterprises for quality improvement can also learn from the methods and experience of HJ.
