Description

Technical Field

[0001] The present application relates to the field of steel bar processing, and more specifically, to a steel bar auxiliary bending mechanism. Background Art

[0002] Steel bars are an indispensable building material in building structures. When used in the production of steel cages, the steel bars need to be bent. The patent document with the prior art publication number CN219616589U provides a bending auxiliary device, which places the steel bars to be bent on the bottom plate and the turntable, and then rotates the screw to drive the fixed block to move through the cooperation of the sliding rod. When the fixed block moves, it cooperates with the side plate to clamp and fix the steel bars. The motor is started to drive the gear to rotate, and when the gear rotates, it drives the gear ring to rotate. When the gear ring rotates, it drives the turntable to rotate. When the turntable rotates, it drives the bending column to rotate and cooperates with the fixed column to bend the steel bars, and then the bent steel bars can be removed.

[0003] In view of the above-mentioned related technologies, the inventor believes that when the steel bar needs to be bent multiple times, the device needs to manually adjust the movement of the fixed block after bending the steel bar once, so that the limit of the steel bar can be cancelled before the bending operation can be performed again, which is not convenient to use. Therefore, we propose a steel bar auxiliary bending mechanism. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a steel bar auxiliary bending mechanism.

[0007] By adopting the above technical solution, the motor and the transmission part cooperate to drive the turntable to rotate reciprocatingly. When the steel bar is placed between a fixed plate and a clamping part, the turntable first drives the cam to rotate when it rotates, and the cam drives the clamping part to move, so that the clamping part and the fixed plate cooperate to tightly clamp the steel bar. Then the turntable drives the bending rod to bend the steel bar. After the bending is completed, the turntable rotates in the opposite direction and resets. The cam does not abut against the clamping part, and the clamping part cancels the clamping of the steel bar.

[0008] Optionally, the transmission member includes a gear A coaxially fixedly connected to the turntable, one side of the gear A is meshingly connected with a transmission rack, one end of the transmission rack is fixedly connected to a driving frame, a crank is slidably connected to the driving frame, and the crank is fixedly connected to the motor.

[0011] By adopting the above technical solution, the slider slides in the arc hole to adjust the position of the bending rod, and the bolt A limits the bending rod after abutting against the turntable, thereby changing the bending angle of the bending rod to the steel bar.

[0012] Optionally, the clamping member includes two connecting rods slidably connected to a fixed plate, the ends of the two connecting rods are fixedly connected to a movable plate, one of the movable plates abuts against a cam, and a spring is sleeved on the connecting rod, and both ends of the spring are respectively fixedly connected to the movable plate and the fixed plate.

[0013] By adopting the above technical solution, when the cam rotates, it abuts against a movable plate, so that the clamping member slides toward the fixed plate and cooperates with a fixed plate to clamp and fix the steel bar.

[0014] Optionally, the cam is fixedly connected to a gear B via a connecting shaft, and the gear B is meshingly connected to an arc-shaped rack fixedly connected to the turntable.

[0015] By adopting the above technical solution, at the initial stage of rotation and the later stage of reset rotation of the turntable, the arc-shaped rack cooperates with the gear B to drive the cam to rotate, and the cam abuts against the movable plate to drive the clamping member to move.

[0016] Optionally, an adjusting rod is slidably connected to the workbench, and one end of the adjusting rod is fixedly connected to a positioning plate.

[0017] By adopting the above technical solution, the positioning plate can position the length of the bent steel bar and improve the bending efficiency of the steel bar.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. The motor and the transmission parts cooperate to drive the turntable to rotate back and forth, so that the turntable drives the cam to rotate in the early stage of rotation. The cam abuts against the clamping part so that it cooperates with the fixed plate to clamp and fix the steel bar. Then the bending rod contacts the steel bar and bends it. The automatic car is high and easy to use.

[0020] 2. The position of the bending rod on the turntable can be adjusted by moving the slider, thereby changing the bending angle of the steel bar, further improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS
