摘要
针对失效模具镶块的修复问题,采用先进的三维扫描技术,获得精确的失效模具的点云数据,进行优化点云处理。结合专业逆向点云处理软件Geomagic Design X,完成了对失效模具模型的重构。通过逆向工程技术,在没有原始模型的基础上,获取了待修复区域的原始模型,实现了对失效模具的建模。依据缺失模具的数字模型,采用TIG自动焊先进技术对失效模具进行修复,得到了修复质量较高的模具镶块。
Focusing on the repair problem of failure die's insert block,the advanced 3D scanning technology was used to obtain accurate point cloud data of failure die,and optimize the point cloud.Reconstruct the failure mold model with professional reverse point cloud processing software Geomagic Design X.Through reverse engineering,the original model of the area to be repaired was obtained under the condition of not having original model,obtaining the model of the failure die to be required.Based on the numerical model with die failure,the advanced TIG automatic welding technology was applied to repair failure die,obtaining mould's insert block with higher repair quality.
