等离子切割炬的割咀,其几何形状和结构尺寸直接关系到切割效率、切口质量和操作方便。过去,我厂加工的等离子切割咀的精度达不到要求,割咀的冷却水路密封性差,易漏水。割咀外形不合理,遮挡了操作者的视线,使割咀易接触工件而短路,烧坏割咀,中断操作。为此,对割咀作图1所示的改进。图2将原来割咀改为两部份,增加了导套。导套与压 Cutting torch cutting torch, the geometry and size of the structure is directly related to the cutting efficiency, incision quality and ease of operation. In the past, I processing plasma cutting Tsui precision of less than the requirements of cutting Tsui cooling water tightness, easy to leak. Cut Tsui shape unreasonable, blocking the operator’s line of sight, the cutting Tsui easy access to the workpiece and short circuit, burned cutting Tsui, interrupt operation. To this end, the cutting Tsui Figure 1 shows the improvement. Figure 2 will be cut into two original Tsui, an increase of guide sleeve. Guide sleeve and pressure
