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. 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. When the steel structure is in use, the corner area needs to be bent before it can be connected. The bending process is generally performed using a bending machine. With the development of science and technology, the functions of the bending machine are constantly being improved so that it can better meet the needs of use.

[0003] In view of this, Chinese Patent No. CN214601181U proposes a bending device for steel structure processing, in which a first screw is driven by a handle to rotate and move toward each other. When the external steel plate is contacted by the sphere and bent, the vertical rod will contact the vertical plate to limit the movement of the vertical rod, so that the user can limit the movement distance of the vertical rod to bend the stainless steel plate at different angles. However, although the fixation of the steel structure in the above technical solution can be adjusted according to the length and volume of the steel structure, in the process of the fixing operation, most steps are performed through manual adjustment, which increases the operating burden of the staff and reduces the efficiency of the bending work. Therefore, an automatically adjustable bending fixing structure is needed. Utility Model Content
