摘要
针对轴承坯料机械手轴盖制件一套三件的成套冲压成型生产要求,运用3D设计软件UG设计了一副11工位连续级进模用于轴盖成套制件的生产。模具中所设计的11工位包括冲孔、落料、拉深、翻边、侧切、侧冲孔等工艺成型手段,模具达到的效果是材料利用率达到64.23%,制件生产效率可达45套/min,模具制造成本降低5%。相比于传统多工序多套单冲模成型工艺,生产效率提高10倍以上。模具中,使用1次拉深成型、3次精修,对多级拉深成型件进行加工能有效降低制件加工难度;使用步进电机送料,氮气弹簧压料和顶料,使模具设计难度大为降低;使用了两种楔紧块驱动型侧滑块机构对制件进行工艺面切除加工和精整形,及燕尾槽压块驱动上模侧冲孔滑块机构使制件的侧面加工得到了可靠保证。使用UG设计软件设计了模具的3D结构,较之于2D排位设计方法,更能有效避免设计缺陷,模具设计效率和可靠性更高。
A set of 11 station continuous progressive die was designed using 3D design software UG to meet the production requirements of a complete set of three parts stamping for electric vehicle axle cover parts.The 11 workstations designed in the mold include punching,blanking,deep drawing,flanging,side cutting,side punching and other process forming methods.The mold achieved a material utilization rate of 64.23%,a production efficiency of 45 set/min,and a 5%reduction in mold manufacturing costs.Compared to the traditional multi process and multi set single die forming process,the production efficiency was increased by more than 10 times.In the mold,using one deep drawing process and three precision repairs to process multi-stage deep drawing parts can effectively reduce the difficulty of workpiece processing;The use of a stepper motor for feeding,nitrogen spring for pressing and top feeding greatly reduces the difficulty of mold design;Two types of wedge block driven side slider mechanisms were used to cut and refine the process surface of the workpiece,and the dovetail groove pressure block driven upper mold side punching slider mechanism ensured reliable side processing of the workpiece.The 3D structure of the mold was designed using UG design software,which can more intuitively avoid potential design defects compared to the 2D placement design method.The mold design efficiency and reliability are higher.
