Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a bending device for steel structure processing. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

[0003] In the processing of steel structures, certain bending operations are required. For example, there is a bending machine with a Chinese patent publication number of CN215032587U. After it is put into use, the component to be bent is placed on two fixed shafts, and the part to be bent is aligned with the pressing shaft, and the lifting mechanism of the pressing shaft assembly is controlled to work. The lifting mechanism drives the pressing shaft downward, and the pressing shaft contacts the component to be bent, and the bending component is pressed down to complete the bending. The downward distance can be adjusted according to the bending angle to complete the bending at different angles. Through the use of the utility model, the factory can bend by itself, which saves time and cost compared to purchasing bending molds; compared with purchasing a bending machine, the cost is lower.

[0004] However, due to the single shape of the final axis of the device, the bending effect is relatively limited and the practicability is insufficient. Utility Model Content
