近日,航天科技集团一院211厂2.25米直径整体旋压箱底通过打压试验,验证了工艺方案的可靠性,具备工程化应用条件,该厂成为国内首家具备大型铝合金贮箱箱底整体制造能力的单位。前期,211厂首次采用旋压技术,实现了2.25米直径贮箱箱底的整体成形。在进行后续机加工时,由于零件尺寸大、壁厚薄,只能采用单面机加工的方式,难 Recently, Aerospace Science and Technology Group 211 Factory a total of 2.25 m diameter spinning the bottom of the tank through the pressure test to verify the reliability of the process scheme, with engineering application conditions, the plant became the first large aluminum tank with the overall manufacturing capacity of the tank bottom The unit. In the early stage, Plant 211 was the first to use spinning technology to achieve the overall shape of a 2.25 meter tank bottom. In the follow-up machining, due to large parts size, thin wall thickness, the use of single-sided machining can only be difficult
