在冷敏、冷挤等成形工艺中,广泛采用两层或三层组合式凹模。过去,对于组合凹模的设计多数由经验或由图表提供数据。在实际生产中当模具因开裂失效时,使用者难以找到真正的损坏原因,这就更难提出防止措施。近来,我们应某厂生产高强度螺栓的需要,对采用镦挤成形的组合凹模作了深入的探讨,建立了一个功能良好的优化设计程序系统。 (1)该程序系统适用范围广。它既适用于量大面广的黑色金属成形工艺,如螺栓、螺母等紧固件冷镦,轴承套圈、滚动体镦挤等组合凹模的优化设计;也适用于有色金属成形工艺,如轻工、日化、电器等产品挤压凹模的优
In cold sensitive, cold extrusion and other forming processes, widely used two or three-tier modular die. In the past, most of the design for a combined die was provided by experience or by charts. In actual production, when the mold fails due to cracking, it is difficult for the user to find the real cause of the damage, which makes it more difficult to propose preventive measures. Recently, we should be a factory production of high-strength bolts need for the use of upsetting extrusion die made in-depth discussion, the establishment of a functional optimization of the design process system. (1) The program system is applicable to a wide range. It is suitable for a wide range of black metal forming process, such as bolts, nuts and other fasteners cold heading, bearing rings, rolling upsetting extrusion die combination optimization design; also applies to non-ferrous metal forming process, such as Light industry, Japan, electrical products such as extrusion die of the excellent
