Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending, in particular to a steel bar bending device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. During the construction process, the rebar usually needs to be bent so that the rebar presents the required ring structure, so a rebar bending device is required.

[0003] The existing steel bar bending device generally consists of a workbench, two sets of positioning bars arranged on the workbench and a driving mechanism. When bending the steel bar, the steel bar is placed on the workbench and passes through the two sets of positioning bars. Then the driving mechanism is started to drive one end of the steel bar to move, and the steel bar is bent under the restriction of the positioning bars, thereby realizing the bending of the steel bar.

[0004] In the existing steel bar bending devices, when bending the steel bars, the bending angle of the steel bars is mostly determined based on the operator's experience, which makes it difficult to bend the steel bars at an accurate angle, and thus the steel bars cannot be bent at an accurate angle; therefore, a steel bar bending device is proposed to address the above problem.

When the slider moves to a suitable angle, the slider is fixed on the track by the locking bolt, and then the motor drives the gear to rotate the gear ring, and then the rotating frame also rotates, so that the rotating frame drives one end of the steel bar to move. When the rotating frame drives the first electrode plate to rotate to contact the second electrode plate, the alarm sounds an alarm, thereby being able to promptly remind the staff to stop the bending operation of the steel bar, so that the steel bar can be bent at an accurate angle, thereby improving the accuracy of the device in bending the steel bar.
