AI Technical Summary

Technical Problem

The steel plates used in safes are not very precise during bending due to the springback of metal stress, and a single bending device cannot adapt to steel plates of different thicknesses and materials.

Method used

A steel plate bending device for safes was designed, comprising a worktable, a fixed plate, a support plate, a limit plate, a positioning plate, a pressure plate, a hydraulic cylinder, and a fixed base. The pressure plate is driven to flip and bend by the hydraulic cylinder, and the bending angle of the steel plate is controlled by the adjustable limit plate and the positioning plate.

Benefits of technology

It improves the accuracy and adaptability of steel plate bending, enabling it to meet the processing needs of steel plates of different thicknesses and materials, and ensuring the stability and accuracy of steel plates during the bending process.
