组合冲模适用于批量不大的板料冲压生产。它是由一组高度标准化、系列化元件组装而成,具有同专用冲模所必需的导向、定位、卸料和刃口工作部份,当完成冲压零件之后,冲模元件可以反复拆装,重复使用。在多品种,小批量,周期短,零件材料、尺寸和形状变化快的研制生产条件下,推广组合冲模,采用分解冲压,是广泛应用的加工方法之一。使用这种加工方法,可以提高冲压零件数量,质量,缩短生产准备周期,节约模具和零件材料,降低研制成本,减小模具的库存面积,加速新产品的试制,促进产品的更新换代,取得了显著的经济效 Combination of die for batch production of small sheet metal stamping. It consists of a group of highly standardized, serialized components assembled, with the necessary special die with the guide, positioning, unloading and edge work, when the completion of stamping parts, die components can be repeated disassembly, re-use . In many varieties, small batch, short cycle, the parts of the material, size and shape changes rapidly under the conditions of the development and production, the promotion of composite die, the use of decomposition stamping, is widely used in processing methods. The use of such processing methods, can improve the number of stamping parts, quality, shorten the production preparation cycle, saving mold and parts materials, reduce development costs, reduce the inventory of mold inventory, accelerate the trial of new products, promote product replacement, and achieved Significant economic efficiency
