AI Technical Summary

Technical Problem

Existing thin-walled sheet metal bending equipment has deficiencies in pressure adjustment and support structure, which makes sheet metal parts prone to wrinkles and deformation during the bending process.

Method used

A thin-walled sheet metal bending anti-wrinkle pressing mechanism was designed, which adopts a limit support component and a feeding component. The limit support roller can adaptively adjust its height, and the feeding platen monitors and adjusts the pressure through a pressure sensor to ensure that the sheet metal parts are subjected to uniform force. Combined with guide sliders and guide rods, the feeding accuracy and stability are improved.

Benefits of technology

It effectively prevents wrinkles from forming on sheet metal parts during bending, improves processing quality and dimensional accuracy, ensures the stability and uniform stress distribution of sheet metal parts during bending, and reduces the probability of deformation and wrinkles.
