哈尔滨工业大学锻压教研室主任王仲仁教授等最近研究成功的球形压力容器成形新工艺于四月十八日通过省级技术鉴定。传统的球形压力容器成形工艺复杂,需要在大型水压机上利用模具压制球瓣及封头,而该成形新工艺既不用水压机,也不需要任何模具,使成本比常规方法降低百分之至三十至五十。新工艺还便于适应不同直径、厚度的球罐成形,具有柔性加工的特点;

Professor Wang Zhongren, director of the forging department of Harbin Institute of Technology, recently completed a successful ball pressure vessel forming process and passed the provincial technical appraisal on April 18. The traditional spherical pressure vessel forming process is complex and requires the use of a mold on the large hydraulic press to press the ball valve and the sealing head. The new forming process can reduce the cost by 30% to 30% compared with the conventional method without using a hydraulic press or any mold To fifty. The new process is also easy to adapt to different diameter, thickness of the spherical tank forming, with flexible processing characteristics;
