Description

technical field [0001] The invention relates to the field of manufacturing technology, in particular to a device and method for superplastic forming. Background technique [0002] As early as the 1960s, superplastic technology has become popular in Western countries such as Britain and the United States, and has received a lot of attention and research from scholars. Complicated parts with different structures can be formed by using the extra-strong plasticity (elongation δ>100%) obtained by superplastic alloys under specific metal structure, forming temperature and deformation rate, but the existing superplastic forming technology has a major shortcoming , that is, holes will be produced during the superplastic forming process, and the generation of holes will produce two results: the first one will lead to the reduction of the physical properties of the formed parts such as tensile strength, yield strength, etc.; the second may be It will lead to premature rupture of t...

Problems solved by technology

Complicated parts with different structures can be formed by using the extra-strong plasticity (elongation δ>100%) obtained by superplastic alloys under specific metal structure, forming temperature and deformation rate, but the existing superplastic forming technology has a major shortcoming , that is, holes will be produced during the superplastic forming process, and the generation of holes will produce two results: the first one will lead to the reduction of the physical properties of the formed parts such as tensile strength, yield strength, etc.; the second may be It will cause the formed parts to be prematurely broken due to the interconnection of holes, etc.

In addition, the molding speed is slow and the output is low

The existing main solution is to adjust the back pressure, but the adjustment is often based on empirical estimation. It is difficult to know exactly how much back pressure should be applied. The human error is relatively large. Experienced people may be able to adjust it. If not, it is a subjective guess. , the effect is not good, or waste energy and time
