由北京市冶金设备自动化研究所和北京钢铁学院机械工程研究所合作,经过三年多的努力,研制成功薄壁短管矫直机,获北京市科技进步奖和冶金部科研成果奖。 通过批量矫直检测表明,该机可用于矫直壁厚与直径比为1/40的短管,其矫直后的母线直线度一般为0.05～0.15mm/m,大大超过了冶金部产品标准(3～5mm/m),达到斜辊矫直技术的世界先进水平(0.1mm/m)。短管椭圆度和表面光洁度均有所改善。 该机采用单机座三辊、两辊合用机型,直流电机拖动,正反转无级调速全驱动。以三点弹性压扁
By the Beijing Institute of Metallurgical Equipment and Beijing Institute of Steel Institute of Mechanical Engineering, after more than three years of hard work to develop a successful thin-walled tube straightening machine, the Beijing Municipal Science and Technology Progress Award and the Ministry of Science and Research Achievement Award. The batch straightening test shows that the machine can be used to straighten the short tube with wall thickness to diameter ratio of 1/40. The straightness of straightening bus is generally 0.05 ~ 0.15mm / m, greatly exceeding the standard of metallurgy product (3 ~ 5mm / m), reached the world advanced level of skew roller straightening technology (0.1mm / m). Short tube ovality and surface finish improved. The machine uses a single stand three rollers, two rollers combined models, DC motor drive, positive and negative stepless speed regulation full drive. Three-point flexibility to flatten
