中文摘要：对大批量生产，运用多工位无废料级进模排样技术，提高材料利用率，降低生产成本是级进模具设计的难点。 以热水器水桶固定支架为案例, 对在多工位无废料级进模排样设计中出现材料重叠、工件定位及步距控制等问题进行了分析, 并提出了解决问题的方案。通过生产证明, 按此方案设计的模具完全满足了用户要求
英文摘要： It is difficulty of multi position progressive die for commencing mass production, with lowering production costs and increasing the material utilization rate, with the application of the blank layout technique with multi position progressive die without waste material. Taken for instance using water heater tank as fixed support, the problem of material overlap during the design of the optimal packing with multi position progressive die without waste, work piece positioning, step control etc, are analyzed and the solutions are presented. With proof from production, the die designed according to the solutions fully meet the demands of the consumer.
