作为飞机钣金件主要成形方法之一的橡皮囊液压成形,具有效率高、成形后零件表面质量好等优点.随着飞机制造业的发展,橡皮囊液压成形在飞机钣金件成形中所占的比重也越来越大.随着CAD技术的发展,基于数字化设计和数字化制造技术的支持,航空企业已广泛应用CAD/CAE等先进技术来实现橡皮囊成形模具的结构设计与优化[1],从模具三维造型设计到模具的数控生产,数字化技术提高了模具的设计与生产精度,缩短模具设计周期,提高企业生产效率,使我国航空企业步入高效生产、精益生产的时代.由于航空钣金件数量大、类型多、模具结构形式多变,橡皮囊液压成形模具在很大程度上仍然依赖设计人员的经验,模具的快速设计已成为模具设计中的瓶颈.

The standard-parts digital model library plays an important role in airplane tooling digital design.It is the key point of high efficiency design building a standard-parts library to adapt tooling rapid design.Two methods in use to build standard-parts library are analyzed.An optimized approach to build standard-part library to adapt rapid design is put forward based the position allocation of standard-parts in tooling and sketch of standard-parts.Basing on characteristics of local database and remote database,the plan to build standard-parts library is given.The standard-parts library built by us is applied in the system of rubber forming die rapid design.The result shows that design cycle and design efficiency are raised great.
