If the size of the plate material 20 is large, the second servo motor 143 can be used for driving the second gear 141 to rotate, and the second gear 141 and the second rack 142 are in meshed transmission, so that the second rack 142 drives the abutting plate 9 to reciprocate along the vertical direction, and the abutting plate 9 can be stably abutted against the plate material 20; this application realizes the stable bearing to sheet material 20 through pivot 5, support board 9, connecting rod 6, bearing box 10 and link gear 11's common cooperation, reduces the possibility that sheet material 20 another side produces great deformation because of receiving the thrust of bending robot 1 to promote the stability when sheet material 20 turn-ups are bent.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
