AI Technical Summary
Traditional precision stamping dies cannot be directly unloaded after the workpiece is formed, especially when the workpiece is large, which requires manual operation, increases costs and poses safety hazards. In addition, traditional unloading systems cannot meet high precision requirements.
A high-precision stamping die was designed. The upper stamping die is driven by a hydraulic press to move vertically along the guide assembly. Spring buffering reduces wear, and automatic unloading is achieved by flipping the guide rod and the cam shaft, which simplifies the workpiece removal process.
It has enabled automated unloading of workpieces, reduced manual operation, lowered safety hazards, and improved unloading accuracy and efficiency.
