|
Through the simulation of sheet metal forming for a car trunk door lock retainer part, combined with the analysis of part process, it was determined to use a double-row progressive die with center carrier to realize its production, and the material utilization rate was 45.6%. Then, the progressive die was designed as eleven
stations including punching, drawing, bending, piercing, blanking, etc. To ensure the dimensional accuracy of parts, the drawing and bending process of parts were completed firstly in the arrangement of stations, and then the punching process of the middle open area was completed. In order to ensure the conveying stability of material belt and the continuous action of progressive die, the die adopted the structure of elastic unloading plate to discharge and the supporting block to sustain the material, and the auxiliary locating hole was added in the middle stage of stamping process, as well as the guide pin was used for positioning. Thus, in the actual production, the die performance is steady and meet the requirements of mass production, and the produced parts reach the design accuracy.
