随着国家减重减排、绿色环保等一系列政策的出台,产品轻量化已经成为时代发展的必然趋势。因此,镁/铝等轻合金高质量高效率的先进制造装备具有极大的研究价值和广泛的市场前景。而在轻合金焊接领域,搅拌摩擦焊被誉“三十年来最具创造性”的发明,是一种绿色无污染的固相连接技术,被广泛应用于航空航天、半导体、轨道交通等领域[1-2]。
常规一维/二维搅拌摩擦焊装备正在逐步取代传统的TIG/MIG焊方法,但受限于自身的结构形状的限制,只能满足形状单一、结构简单的直线或圆弧焊接需求。因此,常规搅拌摩擦焊设备存在兼容性差,较难实现复杂结构件、曲线焊接、匙孔消除等问题。
回抽式三维并联搅拌摩擦焊技术装备实现了铣削/钻孔/焊接/匙孔消除等核心技术的一体化集成功能,能实现复杂结构件的三维曲线焊缝的焊接,满足焊接质量的特殊要求,大大缩减了匙孔后续消除的一系列繁琐问题,该技术是传统二维搅拌焊设备的最佳换代升级产品,具有良好的产业化前景。……
