在轴承生产中,保持器的铆合对产品质量有直接的影响。通常,保持器的铆合是在压力机上进行的,开机后不管有无工件,电机总是带着压力机的滑块不停地运动。近几年,随着流体传动技术的发展,新型压力机不断出现,实践中发现机械式压力机存在下列问题: 1、由于机械压力机不停的运动,而且速度比较高,效率快,使操作者精神紧张,且由于冲头与模具之间的无效行程比较大,工作时
In the production of bearings, riveting the retainer has a direct impact on product quality. Normally, the riveting of the retainer is carried out on the press. After starting the machine, the motor always moves with the slide of the press no matter whether there is a work piece or not. In recent years, with the development of fluid transmission technology, new presses continue to emerge, the practice found that mechanical presses have the following problems: 1, due to the constant movement of mechanical presses, and the relatively high speed, high efficiency, the operation The spirit of tension, and due to punch and die invalid stroke is relatively large, work time
