Description

Angle steel flattening die for power transmission iron tower

Technical Field

The utility model relates to a technical field of steel pylons spare part production and processing, concretely relates to steel pylons's angle steel book flat mould.

Background

The power transmission iron tower is a supporting point of an overhead line, is used as a high-rise structure, is very sensitive to inclined deformation, and has high requirements on uneven settlement of a foundation. The common structural form of the power transmission iron tower foundation comprises an independent foundation, an enlarged foundation and a pile foundation, the structural form of the power transmission iron tower mainly adopts a steel structure, the materials of the power transmission iron tower mainly comprise hot-rolled angle steel, and the production and construction of the power transmission iron tower are generally to design and process various parts in a factory and then assemble and fix the parts in a construction site in a bolt or welding mode.

Because the angle steel of the power transmission tower can cause interference between part of adjacent angle steel when being assembled and fixed. This requires processing of the adjacent angle interference portions. Generally speaking, the angle steel component which can interfere is calculated and designed when the angle steel is produced and designed, and then the angle steel which relates to interference is directly additionally processed in the design and production of a factory, so that the interference is avoided.

Originally, the interference part is directly cut and removed, but the mode directly causes that the corresponding angle steel lacks a certain part and the mechanical property is obviously reduced. The interference position of the angle steel is bent towards the direction far away from the other adjacent angle steel which can interfere, but after the operation, the stress performance of the bent angle steel in the length extension direction of the angle steel is reduced. And finally, two vertical plates of the angle steel at the position of the interference position are simultaneously turned inwards to the position of the center line of the included angle of the angle steel and are mutually attached. The operation in this way can ensure that the mechanical property of the angle steel can be still maintained, and meanwhile, the mechanical property of the angle steel along the length direction can not be influenced.

However, in the conventional bending method, the corresponding part is heated and then is beaten for multiple times by a hammer until the part is attached.
