AI Technical Summary
The existing punching and reaming process for forged aluminum alloy wheels suffers from low efficiency due to the large draft angle and equipment tooling limitations, which necessitates frequent changes of punches of different specifications.
It adopts a multi-punch flap downward punching motion structure and deflection drive assembly. The size and position of the punch flaps are adjusted by hydraulic drive and drive rod to realize multiple punching and expanding operations, eliminating the deformation and imprinting problems caused by punch gap.
It improves the efficiency of punching and expanding holes in forged aluminum alloy wheels, reduces the frequency of punch replacement, and eliminates the deformation and imprinting problems caused by punch gaps.
