今年四月十日至十四日机械工业部基础件局在北京密云召开了液压阀工艺技术经验交流会。这是基础件局贯彻机械工业第三次工艺工作会议精神的具体行动,是我国液压阀工艺技术在近年来所取得的科学技术成果和生产经验的总结。在经验交流会上宣读论文、新工艺和加工经验80多篇。分机械加工工艺、精整工艺、精密测量技术和装配工艺等四个方面十二个专题(平面加工、阀孔加工、阀芯加工、成型加工、密封圈窝加工、平面研磨、沉割槽加工、去毛刺、清洗、防锈、精密测量、装配等),
From April 10 to April 14 this year, the Basic Bureau of the Ministry of Machinery Industry held an exchange meeting on experience in hydraulic valve technology in Miyun, Beijing. This is the concrete implementation of the spirit of the Third Craft Work Conference held by the Basic Materials Bureau and is the conclusion of the scientific and technological achievements and production experience gained by hydraulic valve technology in China in recent years. More than 80 papers, new techniques and processing experiences were presented at the exchange of experiences. Divided mechanical processing technology, finishing technology, precision measurement technology and assembly process in four aspects of twelve topics (plane processing, valve hole processing, valve core processing, molding processing, sealing ring nest processing, surface grinding, sinking slot processing , Deburring, cleaning, rust prevention, precision measurement, assembly, etc.)
