液压机在压力加工生产中的应用已日益广泛,进一步扩大液压机的使用范围,就能更好地为科研和生产服务。现根据我厂实践,介绍扩大液压机使用范围的方法和措施。一、减力冲裁用油压机或水压机作落料、切边、冲孔加工,当加工过程终了时,由于金属分离而突然卸载,会产生强烈的冲击。冲击对设备和模具都造成损害,特别易使液压阀损坏。要防止和避免这种冲击,采取减力冲裁、缓冲冲裁或使用液压缓冲器是最有效的。 Hydraulic press in the production of pressure processing has become increasingly widespread, to further expand the scope of the hydraulic press, we can better for scientific research and production services. Now based on our practice, introduced to expand the use of hydraulic machine methods and measures. First, the reduction of punching hydraulic machine or hydraulic press for blanking, trimming, punching process, when the end of the process, due to metal separation and sudden unloading, will have a strong impact. Impact damage to equipment and mold, especially easy to hydraulic valve damage. To prevent and avoid this kind of impact, it is the most effective to take the punching, the punching or the hydraulic buffer.
