两柱立式液压机系统设计 摘要 液压机是制品成型生产中应用最广的设备之一目前国内大部分企业还沿袭传统方法进行液压机设计导致液压机结构过于保守设计周期长、效率低造成了人力和物力的浪费也影响了产品的市场竞争力ystem Design Of Two-column Vertical Hydraulic Abstract Hydraulic molding machine is manufactured production equipment, the application of one of the most extensive, most domestic enterprises have also followed the traditional method of hydraulic design, resulting in the structure of the hydraulic machine is too conservative, long design cycles, low efficiency, resulting in waste of human and material resources, but also the products market competitiveness, in order to better understanding of the status of its work for the future to improve the efficiency of hydraulic machines. Therefore, I conducted a two-column vertical hydraulic system design. First of all, the load on the system have done a simple analysis, followed by hydraulic pressure through the hydraulic system design, calculation of the system components and various types of valve cylinder technical parameters, in the basis of these data to identify with the hydraulic press match the motor, hydraulic pump stations, and through the data on the system for checking the heat, and further calculate the efficiency of the system, hydraulic pressure at the same time play a supporting role in some components of the selection, the final machine according to hydraulic valve was loss of electrical power to the hydraulic action sequence, action sequence through the hydraulic design of the electrical control system to achieve a combination of mechanical and electrical.
