为了提高我厂加工T10V活塞内孔的质量和推广先进工艺,我们选用了电解加工方法。活塞内孔直径差异较大(图1),且有多个曲率半径交接,当交接处用钻铰方法加工时,很难保证没有刀痕和圆滑过渡,刀痕处由于应力集中的结果,往往由此产生活塞内孔淬火裂纹;这是T10V活塞疲劳折断失效的主要原因之一。故针对提高活塞内孔光洁度和解决应力集中的问题,特采用了电解加工工艺。电解加工是利用金
In order to improve the quality of our factory processing T10V piston bore and promote advanced technology, we use the electrolytic machining method. Piston inner hole diameter difference (Figure 1), and a number of radius of curvature of the transfer, when the junction with the drilling hinge method of processing, it is difficult to ensure that there is no knife marks and smooth transition, the knife marks due to stress concentration results, often Resulting in piston bore quench cracks; This is T10V piston fatigue fracture failure is one of the main reasons. Therefore, to improve the piston bore finish and solve the problem of stress concentration, the use of electrolytic processing technology. Electrolytic processing is the use of gold
