圆锯片振动频率的控制方法

中心夹持高速旋转的圆锯片切削工件时,保持良好的切削稳定性是非常重要的.目前提高锯片切削稳定性的方法有研究新的锯片材料、改善材料性能、改变锯片的结构和几何参数、改变齿形和对锯片进行适张度处理等,对圆锯片采用胀孔适张度处理,在锯片上均布加工一些孔,然后在孔中压入圆锥塞,使之在锯片内产生残余应力场,残余应力场的存在提高了锯片的固有频率,减少锯片的横向振动,从而增加了锯片切削的稳定性.

Vibration Frequency Control Method of the Circular Saw

Please input text in the center grasp high speed whirling circular saw at cutting the work piece, it is very important to keep cutting stability well. At present, the method of improving the cutting stability of the saw blades is studied including the new saw material, improving the structure of material performance, changing the saw and parameter of the geometry, changing the tooth shape and dealing with etc. right each to the saw. Drilling tensioning treatment method is applied at the circular saw blade, some evenly spaced, identical, eccentric holes is drilled at the saw blade, the uniform pressure at the hole can be approximated by mechanically compressing a thin tapered plug into a drilled hole, initial stresses can be induced by the plugs, the ensuing increasing saw blade natural frequencies, reducing the saw blades transverse vibration and improving the cutting stability of the saw blades.
