摘　　要：电火花线切割加工工艺是采用连续移动的金属电极丝作为工具电极,发生放电腐蚀,电火花的瞬时高温使工件表面熔化甚至汽化而腐蚀掉,从而达到加工效果。数控线切割机床使用时,电极丝容易出现重复叠绕、夹丝、断丝的情况;电极丝松弛或过紧都易导致断丝的情况,若电机继续运转,送出的电极丝会缠绕在储丝筒上,造成电极丝报废的。本文针对上述问题,设计一种数控线切割机床的断线保护装置,有效改善了切割机床的断线情况,有效提高机床的加工效率。Wire electrical discharge machining(WEDM)uses continuously moving metal electrode wire as tool electrode,which causes discharge corrosion and makes the surface of workpiece melt or even vaporize.When the NC wire cutting machine is used,the wire of electrode is easy to be rewound,clamped and broken.When the wire of electrode is slack or too tight,it is easy to break wire.If the motor continues to operate,the wire of electrode will be wound on the wire storage cylinder,that caused the electrode wire to be scrapped.In view of the above problems,this paper designs a wire breaking protection device of NC wire cutting machine,which can effectively improve the wire breaking situation and the machining efficiency of the machine.
