摘要：

针对某公司一款产品上的零件——吊环，分析了其结构和材料特性，以及生产工艺。根据吊环的结构形状、尺寸精度和装配精度等要求，设计了由切断、绕弯、折弯3套工序模具组成的复合模具。并制造了一个简易料架作为连冲模具的料架，可以将不规则的边料放置在料架上，再通过一个简易的校正、送料机构，使边料表面变得平整。将简易料架、校正与送料机构和复合模具组合在一起，构成连冲模具。在模具上安装吹气孔，通过高压气体将吊环从模具上吹走。这套针对吊环生产的连冲模具的结构简单、开发成本较低、送料机构简单实用，所生产的吊环能满足公司的实际需求，故障率低，且能有效利用公司的边料，减少浪费。

For lifting ring in a product of a company, its structure，material characteristics and production process were analyzed, and according to the requirements of structure, shape and dimensional accuracy for lifting ring as well as assembling accuracy etc., a compound die including three sets of dies for cutting, roll bending and bending was designed. Then, a simple material rack was manufactured as the material rack of progressive stamping die, and the irregular edge materials could be placed on the material rack. Furthermore, the surface of edge material became flat by a simple correction and feeding mechanism, and the simple material rack, the correction and feeding mechanism and the compound die were combined to form a progressive stamping die. In addition, the blow hole was installed in the die, and the lifting ring was blew off the die by high-pressure gas. This set of progressive stamping die for the production of lifting ring has simple structure and low development cost, its feeding mechanism is simple and practical. Then the lifting ring produced meets the actual needs of company, the failure rate is low, and the edge materials of company are effectively used to reduce waste.
