AI Technical Summary
In traditional bulletproof helmet manufacturing, the blank positioning is unstable, the hole positions are prone to deviation, and manual scribing is difficult to guarantee accuracy, resulting in increased processing costs and time.
The outer mold used for processing bulletproof helmets includes a worktable, a lower mold, an upper mold, a drive assembly, and a power assembly. Through the cooperation of slides, slide plates, and drill bits, the blank is accurately positioned and drilled. The tight pressing of the upper and lower molds ensures the accuracy of the scribing.
This method achieves stable positioning of the blank, avoids hole position deviation and scribing error, reduces processing costs and time consumption, and improves the processing accuracy of bulletproof helmets.
