Description

Technical Field

[0001] This utility model relates to a bending tool, specifically an improved rebar bending tool, belonging to the field of rebar bending technology. Background Technology

[0002] Generally speaking, an improved rebar bender is an important tool used in construction, primarily for bending rebar into specific shapes and angles according to design requirements. Rebar is a crucial material in building structures, used to enhance the tensile strength of concrete and ensure the stability and safety of buildings. On construction sites, rebar typically needs to be processed according to different design drawings, especially requiring bending or shaping to adapt to various structural requirements.

[0003] Traditional rebar bending methods rely heavily on manual labor or simple mechanical equipment, which is not only inefficient but also prone to processing errors, affecting construction quality. Current improved rebar benders have limitations in rebar bending, particularly in adjusting the bending radius, failing to meet more diverse construction needs. Specifically, most traditional improved rebar benders have a relatively fixed and often non-adjustable bending radius; the required bending radius for rebar may vary depending on its location and application. For example, some construction environments may require a smaller bending radius, while certain structural requirements necessitate a larger radius. However, existing improved rebar benders often lack the flexibility to adjust, making it impossible to efficiently complete rebar bending tasks in different scenarios.

[0004] Current improved rebar benders typically employ hydraulic, electric, or pneumatic drive systems, offering advantages such as convenient adjustment and high bending accuracy. However, they suffer from drawbacks in confined spaces and narrow work areas. Their large size makes them difficult to move, requiring significant operating space, resulting in higher costs and a larger footprint. Furthermore, current rebar benders can only bend one rebar at a time, necessitating repeated bending operations. This is time-consuming and labor-intensive, especially for large quantities of rebar, where bending efficiency is extremely low and fails to meet actual construction requirements. In short, they are often very inconvenient.

[0005] Therefore, the key to solving the above-mentioned technical problems lies in developing an improved rebar bending tool that is practical, safe and reliable. Summary of the Invention
