The utility model belongs to the technical field of the device technique of buckling and specifically relates to a reinforcing bar device of buckling. A reinforcing bar device of buckling, includes the workstation, be equipped with motor and rotary disk on the workstation, the motor is connected to the rotary disk, be equipped with the stand on the rotary disk, be equipped with overhead gage and lower baffle on the workstation, be equipped with the slide rail down in the baffle, be equipped with the support column on the slide rail. This kind of reinforcing bar device of buckling is when using, and the angle of buckling according to the reinforcing bar needs raises the back at the control panel, places the reinforcing bar at overhead gage under and between the baffle, and the reinforcing bar is buckled to the starter motor afterwards, has improved the precision of buckling, has also improved work efficiency, and the result of use is good.
