摘要:

 针对已有的电弧增材制造路径规划方法在应用于热锻模具等具有复杂截面轮廓,如内部有空腔或者薄壁结构的待修复目标模型时,存在边缘处阶梯效应、偏移轮廓出现退化边和编程复杂等问题,提出截面内部采用直线扫描填充算法、截面外部采用轮廓偏移填充算法的复合填充方式,使得内部填充均匀并且外部过渡平顺。针对轮廓偏移过程中经常出现的内外轮廓相交情况,提出了解决方案并重点讨论了多边形相交时的几何关系运算。最后,选取某失效曲轴锻模进行电弧增材制造修复实验,修复过程中填充路径使用复合填充方式,实验验证了新方法的有效性。曲轴模具修复结果表明,复合填充方式能够得到机械加工后不存在空隙、夹渣、裂纹等缺陷的模具。

 When the existing wire arc additive manufacturing (WAAM) path planning method is applied to hot forging molds with complex cross-sectional contours, such as the target model to be repaired with a cavity or thin-walled structure inside, there are problems of a step effect at the edge, a degraded edge in the offset contour and programming complexity, etc. Therefore, based on the above problems, a composite filling method that used a linear scanning filling algorithm for the inside of section and a contour offset filling algorithm for the outside of section was proposed to make uniform internal filling and smooth external transition, and according to the intersection of inner and outer contours that often occurred in the process of contour offset, a solution was proposed and the geometric relationship operation when polygons intersected was emphatically discussed. Finally, for a failed crankshaft forging mold, the wire arc additive manufacturing repair experiment was conducted the composite filling method was used to fill path during the repair process, and the feasibility of the new method was verified by experiments. The repair results of the crankshaft mold show that the mold without gap, slag inclusion, crack and other defects after machining is obtained by the composite filling method.
