The utility model discloses a kind of magnesium alloy seamless closed frame. The cast magnesium alloy material is preheated, extruded, cut, electromagnetic induction heating, vacuum high pressure molding, cooling and stripping and heat treatment. The strain induced melting activation method is used to squeeze the extruded plate from the homogenization of the cylindrical cast material and then extruded to get the extruded plate. The extruded plate is placed in the induction heating coil, and the semi-solid billet is obtained through 60 100s, and the mold system is evacuated quickly. Then the blank is placed on the preheated mold and then the high pressure rapid prototyping is made. The utility model uses magnesium alloy to replace aluminum alloy to make a closed frame or box without welds. Before semi-solid forming, it provides sufficient plastic deformation, which ensures that the grain will not grow rapidly in the semi-solid process, ensures the quality of the finished product to be controllable, and can quickly obtain excellent molding properties, and can improve the life of the material. The efficiency of production and the comprehensive performance of finished products can quickly form the complex structure of the box.

一种镁合金无缝闭合框架
本技术涉及一种镁合金框架,特别涉及一种镁合金无缝闭合框架。
技术介绍
众所周知,镁合金具有密度低、比强度高、比模量高、电磁屏蔽性能好、阻尼系数大,易于吸收振动,在碱性环境中稳定性高、在水溶液中腐蚀产物不漂浮、制造成本低、资源广泛等优点,在近代工业制造中逐渐得到推广应用。镁合金制作晶体管集成电路(IC)支架料盒,可以达到重量轻(比现有铝合金材质的支架料盒轻35-45%),为操作带来便利,节省力气,不损伤操作者手臂,而且在碱性环境下化学性质稳定、耐碱性环境能力强,远超铝合金;在一般水溶液环境下的腐蚀产物易于沉淀,可方便控制,而铝合金形成可溶-水解产物,化合物沉淀难以控制,容易污染产品,镁合金制作产品通常采用比较成熟的铸造法(比如压力铸造)、挤压法等,但是许多产品零部件形状复杂,压铸由于含有细密的分散气孔,试验过程中组织架构不稳定易导致泄漏和性能降低,而且复杂形状的零部件不能顺利脱模,因而无法利用压铸法生产;挤压后组织致密,但需要较大量的后续机械加工,导致制造成本飙升,降低了竞争优势,半固态锻造一般流程是,首先直接使用铸态材料或者先将铸态材料进行 ...
