为了制造特大高性能铝合金LD10CYS(AA2014T652)锥环,作者对“四锥两特”新工艺进行了研究,即锥形镦粗、锥形冲孔、锥形环锻、锥形环锻冷变形、特种熔铸工艺、特种热处理工艺.比常规工艺,即先锻成直环再机械加工为锥环,可节省大量金属,并提高锥环的综合性能30%,更突出的是大幅度地提高了锥环使用时的主受力方向(高向)的塑性指标100%. In order to manufacture super high performance aluminum alloy LD10CYS (AA2014T652) conical rings, the authors studied the new process of “four cones and two specials”, namely conical upsetting, conical punching, conical ring forging and conical ring forging cold deformation , Special casting process, special heat treatment process than the conventional process, that is forged into a straight ring and then machined into a cone ring, which can save a lot of metal, and to improve the overall performance cone 30%, even more prominent is greatly improved Tapered ring when used in the direction of the main force (high) plastic index of 100%.
