After the frame 3 moves downwards as a whole, the two conveying devices convey the plate to be shaped to the position of the bearing platform 2 and stop conveying, and at this time, the plate to be shaped is not contacted with the bearing platform 2. Then, the whole frame 3 is driven to move upwards, the bearing platform 2 is contacted with the plate to be shaped, the plate to be shaped is placed on the bearing platform 2, and at the moment, the loading device 4 can shape. After finishing shaping, the conveying device outputs the plate to be shaped.

The first drive cylinder drives the roller 41 toward or away from the weld of the plate to be shaped. Specifically, the first driving cylinder may be a hydraulic cylinder or a pneumatic cylinder, which is not limited in this embodiment.

The stress generated by the force applied by the roller 41 to the weld of the plate to be shaped is greater than the yield strength of the weld of the plate to be shaped. Specifically, the acting force of the first driving cylinder driving the roller 41 to move is the acting force exerted by the roller 41 on the welding seam of the plate to be shaped, the acting force is calculated according to the contact stress between the roller 41 and the welding seam of the plate to be shaped, and the contact stress is larger than the yield strength of the welding seam of the plate to be shaped.

Then, the control device controls the second driving mechanism 43 to drive the roller 41 to approach the welding seam of the plate to be shaped, so that the roller 41 presses the welding seam of the plate to be shaped. Then, the control device further controls the driving motor 423 to drive the gear 422 to rotate, so as to drive the gear 422 to move along the rack 421, and further drive the second driving mechanism 43 and the roller 41 to move along the rack 421, i.e. the roller 41 moves along the welding seam of the plate to be shaped.
