大直径薄壁无缝管材对接试验样机的研发

Development of Butt Joint Test Device for Large Diameter Thin Seamless Steel Tubes

研究了专门用于大直径薄壁管材对接装置,可实现ф1500mm~ф3500mm薄壁管材的对接,对接装置包含管材运送装置和整形装置,运输装置包括水平调节装置和垂直调节装置,可实现两根管材端部中心的对正,和管材的周向角度调节,实现管材运送和对接功能。该装置解决了大直径薄壁管材容易变形造成运输及对接困难,提高了对接效率和成品率,填补了国内技术空白,为进一步研究更大直径薄壁管材的运输及对接方案奠定了基础。

The butt joint devices were developed specially for ф1500 mm-ф3500 mm thin seamless steel tubes. Docking device includes pipe transporting device and plastic device,transportation device includes vertical and horizontal adjustment device,which can realize for center of two pipe ends are,and pipe circumferential angle adjustment. It is convenient and efficient with devices instead of artificial-assisted butt joint to avoid disadvantages of low docking efficiency and unsafe docking process resulting in the foundation for further study of the transportation and docking schemes of thin-walled tubes in larger diameter is laid.
