[0026] The working principle of the utility model is as follows: when bending metal materials, the motor 11 can be driven to drive the screw 12 installed thereon to rotate, and drive the two bending seats 2 installed on the screw 12 through the threaded groove 204 to move, so that the two bending seats 2 slide toward each other on the upper end surface of the base 1, adjust the distance between the two bending seats 2, and then place the metal material on the two bending seats 2, and the two support plates 21 lift the metal material, and then drive the driving rod at its output end to extend through the hydraulic cylinder, and the driving rod drives the stamping seat installed thereon to move downward, so that the stamping seat presses the metal material between the two support plates 21 to bend. In this way, the bending work of the metal material is completed. The distance between the two bending seats 2 can be adjusted according to the bending requirements of the metal material, and the bending angle of the metal material can be changed, avoiding the trouble of replacing different molds to bend the metal material at different angles, saving time and effort, and improving the bending efficiency of the metal material.
