为了去除管类零件端面孔口类、外表面的毛刺以及倒角加工,可采用如图所示的刀具。由于该刀具上的刀片1、7能适应不同内径和外径的管类零件的加工,因而可成倍提高生产率。刀片1用于管类零件外径表面的倒角及去毛刺,它绕自身轴线在刀杆4的槽10内转动;刀片7用于管类零件内径表面的倒角及去毛刺。它中间开有十字形槽8,且可沿刀杆的轴向移动。由于调节螺钉6的凸缘部5嵌入刀片7的十字槽内,因此,调整调节螺钉6,即能保证刀片7达到所需的位置尺寸。刀片1和7,每一面上都有两个切削刃,以适应不同内、外经管类零件的加工需要。固定在刀杆4上的止动圈3的作用是:限制刀片的窜动。而螺钉2则可对刀片和止动圈起定位作用。若刀片1和7的一面已磨损时,只须松开螺钉2,从刀杆中取出刀片并将刀片回转90°后再按相反
In order to remove the end of the pipe parts of the mouth type, the outer surface of the burr and chamfering process, you can use the tool shown in the figure. Due to the tool on the blade 1, 7 to adapt to different diameter and diameter of the pipe parts processing, which can double the productivity. The blade 1 is used for chamfering and deburring of the outer diameter surface of the pipe part which rotates around its own axis in the groove 10 of the arbor 4 and the blade 7 is used for chamfering and deburring of the inner diameter surface of the pipe part. The middle of it has a cross-shaped groove 8, and can move along the axial direction of the arbor. Since the flange portion 5 of the adjusting screw 6 fits into the cross groove of the blade 7, adjusting the adjusting screw 6 can ensure that the blade 7 reaches the desired position and size. Blades 1 and 7 have two cutting edges on each side to accommodate the machining needs of different internal and external pipe types. The function of the stop ring 3 fixed on the arbor 4 is to limit the movement of the blade. While the screw 2 can locate the blade and the stop ring. If one side of the blades 1 and 7 is worn out, just loosen the screw 2, remove the blade from the arbor and turn the blade 90 ° and then reverse
