AI Technical Summary

Technical Problem

When stamping multiple regular hexagonal grooves in the existing battery box cover, the depth of the groove in the middle position cannot be guaranteed, the flatness is inconsistent, and adjusting the equipment parameters is time-consuming and laborious.

Method used

The upper and lower mold bases adopt a sliding connection of guide pillars and guide sleeves. Combined with the regular hexagonal protrusions on the upper mold plate and the grooves on the stripper plate, multiple grooves are stamped at one time through a hydraulic device. The rigidity and stability of the mold are improved by the pad plate and the limiting plate.

Benefits of technology

This achieves uniform force distribution and consistent stamping depth across multiple grooves, eliminating the need for shaping processes, thus improving production efficiency and reducing costs.
