Description

Technical Field

[0001] This utility model relates to the field of building rebar straightening technology, and in particular to a building rebar straightening machine. Background Technology

[0002] A rebar straightening machine is a mechanical device specifically used in the construction field to straighten and correct bent or irregular rebars and automatically cut them to a set length.

[0003] To address this, patent CN212144321U discloses a rebar stretching and straightening device, comprising a base, with fixed columns installed on both sides of the top of the base. A fixed plate is fixedly installed at the top of the two fixed columns, and a hydraulic cylinder is fixedly installed on the top of the fixed plate. The fixed plate has a through hole, and the output shaft of the hydraulic cylinder extends to the bottom of the fixed plate and is fixedly installed with a connecting rod. A first pressure block is fixedly installed at the bottom of the connecting rod. A fixed platform located between the two fixed columns is fixedly installed on the top of the base, and two movable slots are provided on the top of the fixed platform. This invention has a simple structure and is easy to operate. It can quickly and conveniently fix the top of the rebar while also clamping the sides of the rebar, preventing slippage during the stretching and straightening process, thus improving the straightness of the rebar, increasing stretching quality, and improving work efficiency.

[0004] The existing technical solutions described above have the following drawbacks: Although the construction steel bars are first placed on a fixed platform, and then the hydraulic cylinder is activated, the output shaft of the hydraulic cylinder drives the connecting rod to move, and the connecting rod drives the first pressure block to move. The first pressure block fixes the top of the construction steel bars to prevent slippage during the stretching and straightening process. However, the layout and spacing of the straightening blocks in traditional mechanical steel bar straightening machines are usually fixed at the factory. It is difficult for operators to adjust them according to the actual steel bar specifications. When processing steel bars of different diameters, if the straightening spacing is too large, the steel bars cannot be effectively corrected, and the straightened steel bars still have residual bending. If the straightening spacing is too small, the steel bars may be scratched on the surface due to excessive force, which seriously affects the mechanical properties and subsequent use of the steel bars.
