电池连接件多工位级进模设计

Design on multi-station progressive die for battery connector

为了满足电池连接件高精度、大批量的生产需求,确定了采用多工位级进模的方式进行生产。根据制件的结构特点及尺寸要求,设计了多工位级进模的工艺排样,包含冲孔、切外边、拉延成形、空位、落料、切断废料等14个工步,并对模具的整个设计过程及生产要点进行了详细阐述。以Solidworks软件为计算机辅助设计建模工具,绘制出电池连接件模具零件的模型,进行装配后得到本套模具的三维几何模型。模具采用送料机进行送料,采用导料板导料,采用导正销对料带进行精准定位,以保证送料的准确性与稳定性。为提高导向精度,本套模具采用内导柱和外导柱相结合的方式进行导向。同时,设置限位装置及误送检知机构,对模具进行保护。生产结果表明,多工位级进模试制的电池连接件的尺寸与精度能够满足产品的要求。

To meet the production requirements of high-precision and mass for battery connectors, it was determined to use the multi-station progressive die method for production. Then, according to the structural characteristics and size requirements of part, the process layout of the multi-station progressive die was designed, which included fourteen steps such as punching, trimming, drawing, vacancy, blanking, cutting waste, etc., and the whole design process and production points of the die were elaborated in detail. Furthermore, using software Solidworks as a computer-aided design modeling tool, the model of die parts for battery connector was drawn, and the three-dimensional geometric model of the die was obtained after assembling. The die was fed by the feeder, the guide plate guided the material, and the guide pin positioned the material strip precisely to ensure the accuracy and stability of the material feeding. In order to improve the guiding accuracy, this set of die was guided by the combination method of inner guide column and outer guide column. At the same time, a limit device and a false delivery detection device were set to protect the die. The production results show that the size and precision of the battery connector made by the multi-position progressive die can meet the requirements of the product.
