大型锻件喷涂控制及方法研究

Research on Spraying Control and Method of Large Forgings

以大型锻件和表面喷涂的广泛应用为背景,针对人工进行喷涂存在效率较低、工人劳动强度高、安全性低、准确性和均匀稳定性不高等问题,运用信息化和智能化技术,设计了一种新型自动喷涂系统及方法。首先建立锻造喷涂系统的运行坐标系,然后在锻造喷涂系统中输入当前喷涂锻件的相关信息和三维模型确定喷涂方案;其次在锻造喷涂系统上设置视觉成像仪器,确定出锻件在锻造喷涂系统的运行坐标系中的位置,将三维模型匹配到锻造喷涂系统的运行坐标系中,最终按照三维模型上确定的喷涂方案对锻件进行喷涂并对不合格的喷涂区域进行二次喷涂。

Based on the wide application of large forgings and surface spraying,aiming at the problems of low efficiency,high labor intensity,low safety,low accuracy and uniform stability of manual spraying,a new automatic spraying system and method have been designed by using information and intelligent technology.Firstly,the running coordinate system of the forging spraying system has been established,and then the relevant information of the current spraying forging and the three-dimensional model have been input in the forging spraying system to determine the spraying scheme.Secondly,a visual imaging instrument has been set up on the forging spraying system to determine the position of the forging in the running coordinate system of the forging spraying system.The three-dimensional model has been matched to the running coordinate system of the forging spraying system.Finally,the forging has been sprayed according to the spraying scheme determined on the three-dimensional model and the unqualified spraying area has been sprayed again.
