AI Technical Summary
When traditional stamping dies achieve flanging of more than 90°, they need to set up an additional horizontal stamping mechanism, which makes the die structure complex and increases the cost.
A large-angle bending and stamping mechanism is adopted, including an upper die base, a lower die base and a stamping assembly. By utilizing the cooperation of the first inclined block and the sliding seat, large-angle bending and forming are achieved by obliquely extruding the punch on the sliding seat, and the sliding seat is driven to reset through the connecting piece to achieve mold withdrawal.
The structure of the stamping die is simplified, the manufacturing cost is reduced, and the size requirement of the stamping equipment is reduced through oblique stamping, thereby improving the processing efficiency.
