Y24—1177(120)、Y24—3434(350)四柱双动液压拉伸机是为了适应轻工行业对压力加工设备快速高速多规格的需要,由佛山市通用机械厂在生产Y24—1961(200)四柱液压拉伸机的基础上发展试制成功的新产品。已于87年12月中旬通过样机鉴定。该产品设计合理,结构先进。使用了空程快速升降及主油缸自吸充液结构,将液压系统小型化,省掉了大流量泵和大通径的液压件;导柱和主活塞杆采用镀硬铬,提高了
Y24-1177 (120), Y24-3434 (350) four-column double-action hydraulic stretching machine is designed to meet the needs of light industry and processing equipment for rapid high-speed and multi-specification requirements. Foshan General Machinery Factory produces Y24-1961 ) Four-column hydraulic stretching machine based on the development of successful trial of new products. In mid-December 87 passed the prototype identification. The product design is reasonable, advanced structure. The use of fast-empty trip and the main cylinder self-priming liquid filling structure, the hydraulic system is miniaturized, eliminating the need for large-flow pumps and large diameter hydraulic parts; guide post and the main piston rod with hard chrome plating, improved
