产品品种多、规格繁、冲压件占的比重大,是电子、无线电、开关电器、仪器仪表、家用电器等产品制造厂生产的特点。这些厂新产品多、科研与试制任务重、老产品更新换代频繁,所需板料冲压件种类多、变化大、要求生产周期短,一般批量又很小。采用常规全钢冲模制造成本高、周期长,拖长了新产品试制与老产品更新换代的周期。经济冲模具有结构简单、制造简便、成本低的优点。但不同类型的经济冲模,有其一定使用条件和范围,只有选用得当,才能获取良好的经济效益。为促使新产品迅速上马,压缩老产品更新换代周期,降低产品成本,应大力推广经济冲模。本文重点介绍经济冲模的类型、结构特点、应用范围、选用原则及经济效益,供参考。
Variety of products, specifications Fanzhong, stampings accounted for a large proportion of electronics, radio, switching equipment, instrumentation, household appliances and other products manufacturing plant features. These plants have many new products, heavy research and trial production tasks, frequent replacement and replacement of old products, and many kinds of sheet metal stamping parts that require large variations and require short production cycles and small quantities in general. The use of conventional high-cost all-steel die manufacturing, long cycle, dragging a long trial of new products and replacement of old products cycle. Economic die has the advantages of simple structure, easy manufacture, low cost. However, different types of economic die, have certain conditions of use and scope, only properly selected, in order to obtain good economic returns. To promote the rapid launch of new products, compression of old product replacement cycle, reduce product costs, should vigorously promote economic die. This article focuses on the type of economic die, structural characteristics, scope of application, selection principles and economic benefits for reference.
