The angle steel bending device can clamp and fix the angle steel before bending through the threaded connection of the bolt and the sleeve, and the rotational connection of the round roller with the support plate and the clamping plate, thereby improving the stability of heating and bending. At the same time, it will not hinder the movement trajectory of the angle steel during bending, thereby reducing the number of production processes, greatly reducing costs, and improving the efficiency of the bending process. Through the clearance fit between the slide seat and the slide groove, and the active connection between the diagonal rod and the support rod and the slide seat, the high-frequency heating machine can be driven to move back and forth slowly longitudinally through the slide seat when the motor rotates, thereby improving the heating uniformity of the angle steel and ensuring its bending effect.
