Description

Technical Field

[0001] The utility model relates to the technical field of bending, in particular to a Z-shaped steel bending structure. Background Art

[0002] Steel is a strip of steel with a certain cross-sectional shape and size. Ordinary steel can be divided into C-shaped steel, I-shaped steel, angle steel, round steel, etc. according to its cross-sectional shape. Steels of different shapes need to be bent using a bending machine. Most Z-shaped steel bending structures are formed by setting an upper die seat and a lower die seat. The upper end face of the upper die seat and the lower end face of the lower die seat form a Z-shaped structure. The steel is squeezed by the upper die seat and the lower die seat to form a Z shape. However, when the steel is placed between the upper die seat and the lower die seat, the steel is prone to tilt, requiring staff to manually adjust it repeatedly. And after the steel is bent, it contacts the surface of the lower die seat, and it is more laborious to pull it out directly, which affects work efficiency. Utility Model Content
