在分析传统双层金属保温容器制造工艺的局限性及弊端的基础上,提出了可一次性液胀成形出外壳表面具有浮雕图案或文字的双层金属保温容器同步液胀成形工艺。设计了分瓣式液胀成形模具,讨论了模具分瓣数与模具的工作效率、加工精度及模具制造工艺性之间的关系,分析了分瓣式胀形模具自锁功能的设计原则,生产出了一批外壳带有篮球、足球及排球形精美图案的双层金属保温容器。结果表明,为获得外壳表面带有浮雕图案的双层金属保温容器,须对双层金属保温容器的内层和隔热层进行同步加压,并在成形过程中保持内层和隔热层压力相等;分瓣式液胀成形模具应具有自锁功能并尽可能分成偶数瓣。

The limitations and disadvantages of traditional manufacture technology for the double-layered metal vacuum containers were analyzed.A new synchronous hydrobulging one-step process to manufacture the container with empaistic pattern or artistic words on the outer-layer surface was proposed.The sectional hydro-bulging die was designed.The relationships among the number of die sections and the following factors,including the efficiency,machining precision and technology of the die manufacturing were discussed.The design principles of self-lock for the sectional hydro-bulging die were analyzed.Some qualified containers with empaistic patterns of basketball,football and volleyball on the outer-layer surface were produced.The results show that the inner layer and the thermal insulation chambers of the container shall be pressured sychronously to obtain the qualified containers,and the hydraulic pressure in the inner layer shall be equal to the pressure in the thermal insulation chambers during bulging.The sectional hydro-bulging die will own the self-lock function,and the even number of die sections is favorable.
