摩擦片式攻螺纹夹具的设计

The design of the friction slice type tapped tongs

摩擦片式攻螺纹夹具可有效解决生产过程中丝锥强度低、切削条件差、丝锥易折断以及在加工盲孔和锻造件材料时损坏严重,在批量生产时效率不高的难题,提高了产品加工质量和经济效益。

The thesis introduces the working furnishment tongs. Through the practice testifications, this kind of tongs can settle the difficult problems that the tap intension is too low, the cutting condition is too bad, the tap is too easy breakdown, and especially it is even worse when process the bind hole and forging materials, and the too low efficiency in batch manufacture. What＇s more, it can improve the production quality aud advance the enterprise economic benefit.
