摘要： 为研究磁弹磨粒对刀具钝化时刀具位置以及相同位置下刀具旋转方向对钝化效果的影响,基于双磁盘磁力钝化机理建立磁场模型并进行实验验证。首先,在磁场中建立刀具不同位置的仿真模型,应用COMSOL软件分别分析刀具距离磁盘2、4、6、8、10 mm以及10 mm处刀具倾斜30°位置时在磁场中的磁感应强度变化情况;其次,基于磁弹磨粒在双磁盘磁力钝化设备中的钝化机制,制定在不同位置时刀具刃口的钝化实验方案,并对刀具正反转情况进行对比;最后,通过刀具刃口形貌及钝化量讨论刀具在不同参数下的钝化效果。实验发现,刀具在距离磁盘4 mm处钝化效果最好,刀具反转时钝化速度虽慢但钝化精度较高。

Abstract: In order to study the influences of magnetoelastic abrasive particles on the tool position during tool passivation and the tool rotation direction on the passivation effect under the same position,a magnetic field model was established based on the double-disk magnetic passivation mechanism and experimentally verified. Firstly,the simulation models for different positions of the tool in the magnetic field were established. Using COMSOL software,the changes in magnetic flux density in the magnetic field when the tool was positioned at distances of 2,4,6,8,and 10 mm from the disk,as well as when the tool was tilted at 30° at the 10 mm position were analysed. Secondly,based on the passivation mechanism of magnetoelastic abrasive particles in the double-disk magnetic passivation equipment,the passivation experimental scheme of the cutting edge of the tool at different positions was formulated,and the forward and reverse rotations of the tool were compared. Finally,the passivation effect of the tool under different parameters was discussed through the cutting edge morphology and passivation amount. Experiments show that the passivation effect of the tool is the best at a distance of 4 mm from the disk,and the passivation accuracy is high although the passivation speed is slow when the tool is reversed.
