摘　　要：通过对模具成本组成进行系统分析,并对其设计和制造各个阶段的成本核算模型进行研究,提出一个基于模具设计成本、材料成本、加工制造成本、装配成本以及调试成本的综合统计模型。在NX软件上进行成本统计系统的二次开发,通过规则自动识别模具特征,获取成本统计的输入参数,与数据库中的单价进行匹配,自动计算出相应的成本,并以Excel的形式输出详细成本数据。最后,以一套模具的成本统计实例来验证该统计模型的准确性及系统的可靠性。结果表明,该成本统计系统可以获得比较精确的成本,有较高统计效率,可以为汽车模具企业的科学决策提供数据支撑。Through the systematic analysis of the cost composition for stamping die,the cost statistical models for each stage of die design and manufacturing were studied,and a comprehensive statistical model was proposed based on die design cost,material cost,manufacturing cost,assembly cost and try-outing cost. Then,the cost statistic system was second developed by software NX. Furthermore,the input parameters of cost statistic were obtained by automatically recognizing the die features to match the unit price in the database,and the corresponding costs were automatically calculated to output cost statistics in detail by Excel form. Finally,the accuracy of the statistical model and the reliability of the system were verified by an example of die cost statistic. The results show that the cost statistics system can obtain more accurate cost and high statistical efficiency,which can provide data support for the scientific decision-making of automobile die enterprises.
