实践证明:超塑性Zn-22％Al板材在气压成型时具有极大的延伸率,成型性能良好,所用模具结构简单,技术要求较低,制造周期短,成本低廉,操作方便,可应用小设备成型大工件,节约能源。故特别适宜于新产品试制和中、小批量生产大型复杂型面及变形量较大的板材成型工件。显然,这一新方法的应用,给产品结构设计提供极大的方便,为金属板材成型开辟了新的途径,这是一项很有推广应用价值的新工艺,它在金属加工中具有广阔的前途。
Practice has proved that superplastic Zn-22% Al sheet has great elongation during air pressure forming, forming performance is good, the mold structure is simple, low technical requirements, short manufacturing cycle, low cost, easy to operate, the application of small equipment Forming large workpieces saves energy. It is particularly suitable for trial production of new products and small and medium-sized production of large complex profiles and large deformation of the sheet metal forming parts. Obviously, the application of this new method provides great convenience to product structure design and opens up a new way for metal sheet forming. This is a new technology with great promotion and application value. It has a wide range of applications in metal processing future.
