Description

Technical Field

[0001] This utility model relates to the technical field of rebar straightening devices, and in particular to a rebar straightening device for building construction. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, and sometimes square with rounded corners. During the production, transportation, and storage of reinforcing bars, they are very prone to bending when subjected to external forces such as collisions or improper storage. Therefore, reinforcing bars need to be straightened using reinforcing bar straightening devices to ensure their usability.

[0003] Patent application CN202121281510.2 discloses a rebar straightening device for building construction, including a straightening box. A base is fixedly connected to the left side of the bottom of the inner cavity of the straightening box, and a straightening groove is formed on the top of the base. A power box is fixedly connected to the left side of the top of the inner cavity of the straightening box, and a first motor is fixedly connected to the rear side of the inner cavity of the power box. This utility model has the advantage of good straightening effect and solves the problem that most existing rebar straightening devices for building construction straighten the rebar by directly pulling it, so that the rebar is straightened under the action of mechanical external force.

[0004] The rebar straightening device proposed in the aforementioned patent document only limits and fixes one end of the rebar during actual use. This makes it easy for the other end of the rebar to move during the pressing and straightening process, affecting the straightening effect. Furthermore, the device cannot automatically clean the dirt on the surface of the rebar.

[0005] Therefore, those skilled in the art have provided a steel reinforcement straightening device for building construction to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rebar straightening device for building construction. A second servo motor drives a second bidirectional threaded rod, allowing the clamping block to be adjusted horizontally in the forward and backward directions, thus stabilizing the rebar. Simultaneously, a first servo motor drives a first bidirectional threaded rod, causing a first sliding block to move the mounting frame and clamping block horizontally in both directions, thereby straightening the rebar and reducing the need for manual adjustment. Furthermore, a third servo motor drives a unidirectional threaded rod, causing the second sliding block to adjust the straightening roller and cleaning brush horizontally in both directions. A hydraulic rod allows for vertical height adjustment of the straightening roller and cleaning brush. The combination of the first and second electric telescopic rods enables multi-dimensional control of the straightening roller and cleaning brush positions. The cleaning brush automatically removes dirt from the rebar surface while straightening, ensuring rebar cleanliness and facilitating subsequent construction processes.

[0007] To achieve the above objectives, the present invention provides the following technical solution:
