介绍了用多点成形法实现无模曲面造型的主要原理、特点及所研制的相应装置 ,并用实验结果证明了其成形效果。通过比较 ,论证了多点成形不仅可实现板材的三维曲面无模造型 ,而且具有明显的技术特点
The main principle, characteristics and corresponding devices developed by using multi - point forming method are introduced. The forming results are proved by the experimental results. By comparison, it is demonstrated that multi-point forming can not only realize the three-dimensionally curved mold-free shape of the plate but also have obvious technical characteristics
