Description

Bending device

Technical Field

The utility model relates to the technical field of aluminum bending, in particular to a bending device.

Background

Aluminum materials are manufactured from aluminum and other alloying elements. It is usually produced by processing into cast product, forged product, foil, plate, band, pipe, rod, section, etc., and then cold bending, sawing, drilling, assembling, coloring, etc. The main metal element is aluminum, and the performance of the aluminum material is improved by adding some alloy elements.
