瓦口减薄量的加工通常采用胎具对口处强制变形的方法来实现,但是这种方法很难控制削薄量的尺寸和削薄高度,特别是对于壁厚较厚的轴瓦.2倾斜镗头加工方法轴瓦行业目前推行一种新的加工方法.将镗床的镗头相对进刀运动方向设置一个倾角,在镗杆上前后装上两把镗刀,如图1所示.这样两把镗刀的回转中心相对于溜板运动方向就存在了一个偏心量,前刀用于镗壁厚后刀用来镗瓦口削薄,这样即可实现壁厚与瓦口削薄一次加工完成.但是,本文将着重介绍的是根据产品图纸的削薄要求,来进行前后两把刀的偏心量计算的计算公式,及其推导过程,以供读者参考.
The process of reducing the amount of watts is usually achieved by the method of forcing deformation at the mouth of the mold, but this method is difficult to control the size and the height of the thinning, especially for the bearing with thick wall.2 The tilt boring head Processing methods Currently, the bearing and bearing industry has introduced a new processing method, setting the boring head of the boring machine at a tilt angle relative to the direction of feed and installing two boring tools on the boring bar, as shown in Figure 1. In this way, two boring tools Of the center of rotation relative to the direction of movement of the slide there is an eccentric amount, the front knife for boring the wall thickness knife for the boring tile thinning, so you can achieve the wall thickness and tile cut thin a processing completed. However, Emphasis is introduced according to the product drawings of the thinning requirements, to carry out before and after the two knives eccentricity calculation formula, and its derivation process for readers reference.
