Abstract
The invention discloses a plate bending mechanism based on extensible bending rods. The plate bending mechanism comprises a support, a lower rotating table, an upper rotating table, a bending baffle and a motor, wherein the lower rotating table and the upper rotating table are in shaft connection with the support, the bending baffle is fixed with the support and located between the lower rotating table and the upper rotating table, and the motor is installed on the support and drives the lower rotating table and the upper rotating table to rotate. The bending rods are arranged on two sides of the bending baffle, and a driving mechanism driving the bending rods to extend is installed on the lower rotating table or the upper rotating table. Bending is achieved through two bending rods which are extensible freely, and due to the fact that the bending rod on one side not needing bending can be retracted, the problem of bending interference is solved. In addition, the bending rods can be arranged to be closer to the bending baffle, so that the bending torsion generated by the motor with the same power is larger. Meanwhile, the contact distance between the plate bending mechanism and a plate can be shortened in the bending process due to reduction of a bending radius, surface scratch is effectively reduced, and accordingly low-scratch, low-interference and efficient bending is achieved.
