Description

Technical Field

[0002] In construction, rebar bending refers to the process of bending rebar into a specific angle or shape using manual or mechanical means. The purpose of rebar bending is to conform the rebar to the shape required by the design drawings, facilitating its reinforcing function within the concrete. Rebar bending requires a certain level of skill, especially when bending thicker rebars. Manual operation is very strenuous, and workers without proper tools or experience are prone to improper handling, leading to inaccurate bending angles or shapes that do not meet design requirements. This is particularly true in projects requiring a large number of rebar bends, where manual operation is inefficient and lacks precision. Improper operation can also cause the rebar to crack or be bent at an inappropriate position, resulting in wasted rebar and increasing the risk of worker injury.

[0003] Currently, the steel bar bending equipment used in the market can bend steel bars, but the existing structures are either complex, costly, complicated to operate, inconvenient to transport, occupy a lot of space, and are difficult to maintain; or they are too simple, which cannot guarantee the consistency of the bending angle and shape of the steel bars, making it difficult to control the quality, and is also time-consuming and labor-intensive.
