Description

Technical Field

[0001] This utility model relates to the technical field of angle steel production equipment, specifically a steel plate bending device. Background Technology

[0002] Transmission towers are structures that support the conductors and lightning protection wires of high-voltage or ultra-high-voltage overhead transmission lines. They are generally classified into five types according to their shape: goblet-shaped, cat-head-shaped, U-shaped, T-shaped, and barrel-shaped. According to their purpose, they are classified into tension towers, straight-line towers, angle towers, transposition towers, terminal towers, and crossing towers. Angle steel is a crucial component in tower construction. During tower construction, angle steel often needs to be bent. Since angle steel is originally a steel plate of a certain size, it requires a bending device to bend the steel plate.

[0003] A rapid bending device for producing angle steel for iron towers, as disclosed in announcement number CN215614277U, includes a frame with a mounting frame fixedly installed on it. A feed wheel and multiple sets of bending wheels are sequentially mounted on the mounting frame, both rotating on the mounting frame. The feed wheel consists of upper and lower flat wheels, while the bending wheels consist of upper and lower concave and convex wheels. A motor is fixedly installed on the frame, and the motor is connected to the lower wheel of the feed wheel and the concave wheels of the multiple sets of bending wheels. Through the arrangement of multiple sets of bending wheels, the flat steel plate gradually reaches the required bending angle after passing through the bending wheels sequentially. The bending speed is fast, and the bending is less prone to springback, thus improving both bending efficiency and quality. This invention has a simple structure and is easy to operate, making it worthy of promotion. Furthermore, existing bending devices have the following disadvantages in use:

[0004] The distance between the convex wheels of the existing bending device cannot be adjusted. Since steel plates have different thicknesses, a fixed wheel spacing may not be able to accommodate steel plates of all thicknesses for bending, resulting in poor bending effect or inability to perform bending operations.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
