Design of 3D multi station progressive die for bearing blank robot shaft cover
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.
