After the return air duct is bent on a bending machine, in order to better connect with the air conditioner during use, it is necessary to place it on a shaping tool for angle shaping. The purpose of shaping is, on the one hand, to trim the bending angle that is not in place, and on the other hand, to inspect the bending quality of the return air duct through the shaping tool.

During the shaping, the driving disk 17 drives the lead screw 15 to rotate, and the lead screw 15 further drives the push plate 16 to apply a forward thrust to the connecting section 7. The connecting section 7 rotates counterclockwise around the shaping cylinder 28 under the action of the thrust, and finally the end of the horizontal part abuts against the side of the reference plate 13.
