AI Technical Summary
Existing stamping dies require multiple stations to form the connecting arm, resulting in high die costs and an increased likelihood of malfunctions.
The connecting arm is formed in two steps using an outer contour punching assembly and a connecting arm punching assembly. The outer contour punching assembly is used to remove the part other than the connecting section, and the connecting arm punching assembly is used to form the connecting arm at the outer position of the outer contour of the material sheet.
This allows for the formation of connecting arms with lower mold costs and fewer workstations, reducing the likelihood of anomalies and improving material utilization.
