This progressive stamping die is designed for high-volume production of SUS304 motor housing. The whole process adopts step-by-step deep drawing to avoid cracking and wrinkling. The dual pilot positioning system ensures stable dimensional accuracy, while the modular structure allows quick change and easy maintenance. Key wear parts are treated with high-hardness surface coating to extend service life and reduce production costs.
Design & Process Highlights
- Step-by-Step Drawing Anti-Cracking Process: Adopts multi-stage progressive drawing with intermediate process compensation to avoid cracking and wrinkling during deep drawing of stainless steel, ensuring uniform and stable wall thickness.
- Modular Quick-Change Structure: Key forming stations adopt replaceable module design, which is convenient for maintenance, die repair and replacement, greatly reducing downtime and maintenance costs.
- Dual Pilot Positioning System: Pre-pilot at the first station + secondary fine pilot between stations, ensuring the coaxiality between product holes and outer circle ≤0.02mm to meet the assembly requirements of motor housings.
- High Wear-Resistant Treatment: Punches and dies are treated with TD coating, achieving surface hardness up to HV2800, significantly extending die service life.
