AI Technical Summary
The existing fine stamping pressure ring structure, under the requirements of complex process stations, has a force transmission range limited to within a diameter of 300, which results in uneven pressure distribution, leading to a decrease in stamping accuracy and a reduction in product qualification rate.
The rigid connection structure of the pressure ring body, arc plate and expansion screw is adopted. Combined with the combination design of guide plate, sliding plate and spring, the vertical pressure is converted into a uniformly distributed force by the contact between the arc plate and the die punch, and the impact vibration is absorbed by the spring to extend the service life.
This achieves uniform pressure distribution to the mold base, reduces stress concentration, improves work efficiency, and extends service life.
