摘要:
目前, 大型水轮机金属焊接蜗壳各分节大多采用按各分节平面展开线轮廓进行数控切割加工。但各分节间的环焊缝都是 分段切割为定角度坡口面, 这样形成的环焊缝实际焊接坡口角是变角度的, 这不符合最佳焊接工艺要求。为了实现等角度环焊 缝坡口面切割, 就其推导出数控切割的数学模型。
Abstract:
At present , each sectionalization of large -scale spiral case is produced by NC cutting according to the outstretched plane of the curve of the sectionalization .But annular welding seam between the sectionalizations is cut at the fixed angle of awelding grooved face .The welding grooved angle formed in this method is changed .It does not fit in the demand of the best welding echnology .In order to cut at the equal angle of the welding grooved face of annular welding seam , a mathematical model is derived for numerical control of cutting devices .
