Description

Technical Field

[0001] The present application belongs to the technical field of steel bar bending, and specifically relates to a steel bar bending device. Background Art

[0002] Rebar bending is the process of bending steel bars, that is, bending straight steel bars into the required shape or angle by mechanical or manual means. This process usually requires the use of a bending machine or bending machine. These devices can accurately control the bending angle and bending radius. Rebar bending is a common process in civil engineering projects such as buildings, bridges, and roads. It is used to meet structural design and construction needs. The bent steel bars can be used to construct structural components of various shapes, such as beams, slabs, columns, etc. This process requires precise operation to ensure that the bent steel bars meet the specification requirements and do not affect the safety and stability of the structure.

[0003] For example, the utility model patent with announcement number CN218946199U discloses a steel bar bending device for construction, which relates to the technical field of steel bar bending devices, including a cabinet, the top of the cabinet is fixedly connected to a motor, the output end of the motor is fixedly connected to a turntable, the middle part of the top of the turntable is fixedly connected to a fixed bending column, the top of the turntable is provided with a steel bar body, the turntable and the top of the cabinet are provided with an adjustable bending component, and the side wall of the adjustable bending component is provided with a stabilizing component; in the technical solution provided by the utility model, the disclosed adjustable bending component drives the movable bending column to move toward the fixed bending column by extending the first hydraulic cylinder to clamp the steel bar body in the middle. Similarly, the limit plate moves to fit the steel bar body, which is convenient for adjusting the size of the bending structure according to the size of the steel bar. There is no need to use bending structures of different sizes to bend steel bars of different sizes, thereby improving the convenience of use.

[0004] The device rotates the turntable by the rotation of the motor, so that the fixed bending column and the movable bending column rotate with the fixed bending column as the center of the circle, and the clamped steel bar body rotates and bends with the fixed bending column as the fulcrum, thereby achieving the effect of bending the steel bar body;

[0005] However, if the steel bar body of the device needs to be bent in the opposite direction after being bent on one side, personnel need to remove the steel bar body and flip it over, and then put the flipped steel bar body into a fixed structure for re-clamping and bending. This is time-consuming and labor-intensive, and it is difficult to continuously bend the steel bar body in different directions. For this purpose, a steel bar bending device is provided.
