摘　　要：通过产品系列化拓展,推出3款蜗壳产品图。对3款蜗板的工序加工图进行工艺优化,以经济且规整的群孔替代原产品的群孔。为解决系列化拓展后蜗板超宽、多型孔的冲压加工难题,对液压折弯机作系统化改良,成为可用的电液伺服折弯机,提供了加工设备保障。经对3款蜗板开展冲压加工分析,拟用一台电液伺服折弯机匹配一套由滑板行位控制、移动式跳步的组合冲孔模来进行群孔加工。通过群孔列表推演,能实现群孔加工。经验证,优化后蜗板的超宽孔距、多孔型加工符合要求且品质得到提升;对比原手工加工,采用改良折弯机配套组合冲孔模能显著提高加工效率。对设备进行改良并配套优化模具,是实现企业“降本增效”的好途径。Through the expansion of product seriation,three volute product diagrams were introduced.The process optimization on the three types of volute plate process machining diagrams was carried out to replace the group holes of original product with economical and regular group holes.In order to solve the stamping process problem of ultra-wide and multi-shaped holes for the volute plate after seriation expansion,the hydraulic bending machine was systematically improved to become a usable electro-hydraulic servo bending machine,which provides the processing equipment guarantee.After analyzing the stamping process of three types of volute plate,an electro-hydraulic servo bending machine was proposed to match a set of combined punching die controlled by slide row position and with mobile skip step for the maching of group holes.Group hole machining can be realized through the of deduction group hole list.It is proved that the processing of ultra-wide hole spacing and multi-shaped hole for volute plate after optimization meets the requirements and the quality is improved.Compared with the original manual machining,the efficiency of machining can be significantly improved with the combined punching die and the improved bending machine.It is shown that the equipment improvement combined with die optimization is a good way to achieve“cost reduction and efficiency increase”.
