在中小型液压机和多层热压机的运动系统中,活动横梁平行移动的精度,对于设备的使用寿命与制品的质量影响很大。活动横梁的平移精度,实际上就是与该梁刚性连接的一个或几个工作油缸柱塞的同步精度问题。其同步性好,横梁的平行移动精度就高,这有利于压机克服偏心载荷,减少机身的附加弯矩。传动平稳,利于延长工作缸导套和密封元件寿命。同时,制品的质量也将大大改善。在中小型液压机和多层热压机中,不管负载如何,都要求有高的活动横梁平移精度。这
In the small and medium-sized hydraulic press and multi-layer pressing machine’s motion system, the accuracy of moving the parallel beam moves greatly for the service life of the device and the quality of the product. The translation accuracy of the moving beam is in fact a matter of the accuracy of the synchronization of the one or several working cylinder plungers rigidly connected to the beam. The synchronization is good, the beam parallel movement accuracy is high, which is conducive to overcome the eccentric load on the machine to reduce the body’s additional bending moment. Transmission smooth, conducive to extending the working cylinder guide and seal components life. At the same time, the quality of products will also be greatly improved. In small and medium-sized presses and multi-layered presses, high cross beam translation accuracy is required regardless of load. This
