The basic process comprises two main paths:
Blanking: Suitable for processing thin plates with a thickness of 0.5-1.2mm. Forming is achieved through the shearing action of a punch and die, with a processing accuracy of ±0.05mm.
Forming: Utilizes multi-station progressive dies for forming complex curved surfaces. The die structure includes auxiliary components such as guide sleeves and spring-loaded ejection mechanisms.
Key Process Developments:
Hot Stamping: Sheet metal is heated to 860-900℃ and then stamped, with quenching and strengthening achieved through a die cooling system.
Complex Heat Treatment: Includes a chain of processes including carburizing (980-1050℃ × 6h), oil quenching (220-240℃), and tempering (240-280℃).
Automated Processing: A patented device will enable automated loading and unloading by a robotic arm by 2025, combined with a detection structure to achieve 100% online quality inspection.
