Spraying Method and Optimization of Process Parameters for Remanufacturing Profiled Workpieces Based on Coating Model

再制造零件的涂油保护是其以完好的质量状态进入新生命周期的关键技术之一。针对多品种大批量形状不规则难以装夹的再制造异形件,不易规模化涂油保护问题,基于平面和曲面涂层生长模型,提出一种绕中心轴线公转、相对周边自转,在密闭环境辅以自重驱动的再制造异形件喷涂油方法,并对喷涂机构数量、喷涂机构安装位置、喷涂距离以及喷嘴数量等主要工艺参数进行分析计算。为提高喷涂均匀性和喷涂效率,在分析喷涂质量影响因素的基础上,建立喷嘴位置与工件转速优化模型,通过粒子群算法求解得到最优设计参数,仿真试验验证了模型的正确性和求解方法的有效性。

The oil-making protection of remanufacturing parts is one of the key technologies for entering the new life cycle with good quality. The remanufacturing profiled workpieces in a variety of large quantities of irregular shape which are difficult to clamp are not easy to scale oil protection. Based on the growth model of plane and surface coating, the oil protection method that the remanufacturing profiled workpieces driven by their own weight rotate around the central axis and around the center in the closed environment is proposed. The number of spraying mechanism, the spraying mechanism position, spraying distance and the nozzle number and other key parameters are calculated. In order to improve the uniformity of spraying and spraying efficiency, based on the analysis of influence factors on the quality of spraying coating, the optimization model of nozzle space and workpiece speed was established, the optimal design parameters are obtained by particle swarm optimization(PSO). Simulation test verify the correctness of the model and the effectiveness of the calculation method.
