一种渐切内孔刀制造技术
A gradual Qieneikong knife
The utility model discloses a gradually Qieneikong knife; including a cutter head and a cutter rod; the cutter head comprises a main cutting edge and an auxiliary cutting edge, rake face, back, back side; the main cutting edge and cutting edges respectively an arc; the main cutting edges intersect with the auxiliary cutting edges for an arc smooth connection, the main cutting edge, side cutting edge intersection without inflection point; the rake face of 1c and the main cutting force was acute angle between the direction of. Advantages: reduce the impact of intermittent cutting on cutting tools. To reduce the transmission mechanism of machine tool tool clearance on impact, impact on cutting tools have become the thrust of progressive cutting force, to avoid the traditional knife cutting tool; reduce the instantaneous displacement caused by the impact of cutting knife, the cutting smoothly, avoid the bar knife, knife bite phenomenon, reduce the the damage caused by the impact of the cutting tool, the machining accuracy is greatly improved, to avoid causing a dagger, eating knife phenomenon such as scrap.
【技术实现步骤摘要】
一种渐切内孔刀
本技术属于刀具
，涉及一种渐切内孔刀；特别适用于表面不规则、表面凸凹起伏、斜孔相交、内表面断续不完整的内孔切削加工。
技术介绍
常用内孔刀如图1所示，包括前部刀头1、后部刀杆2；前部刀头1包括主切削刃1a、副切削刃1b、前刀面1c、主后面1d、副后面1e、刀尖1g；主切削刃1a、副切削刃1b为直线形刀刃；刀尖1g，一般为小段过渡圆弧；主切削刃1a与副切削刃1b相交处1g为直线形刀刃的拐点。在切削过程中，刀杆2安装在机床刀架上，内孔刀与工件内表面直接接触切削掉加工余量，内孔刀的刀尖和主切削刃直接与内表面接触；传统内孔车刀切削沿切削方向f切削进给时，刀具的切削部分要承受很大的压力、摩擦、冲击和很高的温度；内孔车刀切削的冲击力方向与进给相反，使刀杆受冲击力的挤压产生弹性变形引起震动，切削推力所产生的让刀造成的扎刀和啃刀现象。尤其是当内孔表面不规则，内孔切削呈现为断续的撞击性切削；在大型工件上表现尤甚。常用内孔刀加工的缺陷通常表现为：刀具受到是撞击性切削，车刀受的冲击力较大，断续撞击性使刀杆在切削时瞬间产生了对工件轴心线的位移，易产生圆柱度超差；撞击...
