针对现有水再约束等离子弧加工中存在容易断弧等问题,提出了把水射流“焦平面”与被切割工件上表面重合的水再约束方案,并分析了该方案中再约束水流量对弧柱稳定性及切口质量的影响。
In order to solve the problem that existing arc re-confined plasma arc machining is easy to be interrupted, the water regaining scheme is proposed to reconstruct the “focal plane” of the water jet and the upper surface of the workpiece to be cut, and the re-constrained water flow rate Effect of arc column stability and incision quality.
