The invention discloses a thin-wall metal inflation rod device, and relates to the technical field of inflation anti-instability rods. The device comprises a thin-wall metal rod body, the top end of the thin-wall metal rod body is closed, the bottom end of the thin-wall metal rod body is provided with an opening, the bottom end of the thin-wall metal rod body is coaxially provided with an end cover, the center position of the end cover is coaxially provided with an inflation guide rod, and the inflation guide rod penetrates through the end cover and is communicated with the thin-wall metal rod body; and a base is coaxially mounted below the end cover. According to the thin-wall metal inflation rod, the whole thin-wall metal inflation rod is designed in a split mode, the thin-wall metal inflation rod is structurally divided into the thin-wall metal rod body and the end cover, the thin-wall metal rod body and the end cover are machined through stamping and numerical control turning processes respectively, the machining difficulty and the machining cost are greatly reduced, the arranged base can enhance the stability during inflation, and the machining efficiency is improved. And moreover, the characteristics of the axial pressure experiment working condition of the universal testing machine are fully considered, the axial pressure experiment can be carried out without other mounting steps, and the operation steps are simplified.
本发明公开了一种薄壁金属充气杆装置,涉及充气防失稳杆技术领域。本发明包括薄壁金属杆身,所述薄壁金属杆身的顶端设置封闭,底端设置有开口,且薄壁金属杆身的底端同轴安装有端盖,端盖的中心位置同轴安装有充气导杆,且充气导杆贯穿端盖并与薄壁金属杆身相互贯通;所述端盖的下方同轴安装有底座。本发明提出的薄壁金属充气杆整体采用分体式设计,将薄壁金属充气杆结构分为薄壁金属杆身和端盖两部分,分别采用冲压和数控车的工艺进行加工,极大地降低了加工难度与加工成本,且设置的底座不仅能够增强充气时的稳定性,保持气体稳定输送,而且充分考虑了万能试验机轴压实验工况的特点,无需其余安装步骤即可进行轴压实验,简化操作步骤。
