拉削注意事项
拉刀铣削容载的计算出
Calculation of pulling force
预想加热器端差率(kgf) =车削加工厚度(mm)x1刃的切深(mm)x机关单位使用面积车削加工压力差(kgf/mm²) x同样车削加工刃数很安全加热器端差率(kgf) = 1.8x预想加热器端差率(kgf)
预想载荷是拉刀在硬性环境下激光加工时候须要的切销力。 随着时间推移拉刀钢刀的总是磨损前提.就须得逐斩扩大投入切销力, 但扩大投入到相应因素后拉刀会划痕 , 一些因拉床的维系环境不恰当的而在切销中熄火。 人身安全载荷也就是说 关键在于以防止存在以上前提的能切销力 。
Calculation of pulling force Expected force(Kgf) =Cutting width x Cutting depth/1 tooth(mm) x specific cutting resistance(kgf/mm²) x number of simultaneous Safety load(kgf)=1.8 x Expected force(kgf).
Expected force means that necessary cutting force for broaching under norma1 condition. Safety load is permitted cutting force.
拉刀总长度和拉床旅行线路的关心
Broach cutter length and machines stroke
拉刀的间距要会受到拉床的往返及组合夹具的限制 。
拉刃口长+前部柄长(MAX)= (最明显路程) - (零件钻削总长)
营养里程=刃长+零部件切屑总长+后柄总长<拉床更大里程
根据產品在总是的改良中,样品技术水平因素若有涂改,恕不额外通知短信。
Broach cutter length and machines stroke Broach length is limited by machine stroke and jig/fixture
Broach cutter teeth length+length of rear shank=(Max stroke)-(cutting length)
Necessary stroke=Teeth length+length of rear shank+Broaching length<broaching machine stroke(max)
