一种线切割导轮总成
本技术涉及金属线切割
,尤其涉及一种线切割导轮总成。
技术介绍
线切割,其基本工作原理是利用连续移动的细金属丝(称为线切割的电极丝)作电极,对工件进行脉冲火花放电蚀除金属、切割成型。线切割主要用于加工各种形状复杂和精密细小的工件,例如线切割可以加工冲裁模的凸模、凹模、凸凹模、固定板、卸料板等,成形刀具、样板,线切割还可以加工各种微细孔槽、窄缝、任意曲线等。线切割有许多无可比拟的优点,比如线切割具有加工余量小、加工精度高、生产周期短、制造成本低等突出优点,线切割已在生产中获得广泛的应用。金属线切割中其金属丝的移动是通过导轮总成实现的,导轮总成主要由导轮、导轮轴、轴承和导轮座构成,导轮圆周面上设有导线槽,导线就落在导线槽内,导轮安装在导轮轴上,导轮轴两端则安装在轴承上,轴承外是导轮座。当前线切割机高频导电方式是:负极由切割线直接压在导电块摩擦导电。加工过程中切割线丝高速摩擦导电块,造成切割线丝磨损、导电块形成切割线丝糟,切割线丝糟增大运丝阻力经常夹断切割线丝,导致切割线异常提前报废,导电块需要经常更换等缺点。
