A pressing block 5 is arranged above the lower workbench 2, and a second flanging die 6 is arranged on the right side of the pressing block 5. A forming groove 61 is processed at the lower part of the second flanging die 6 to cooperate with the right part of the lower workbench 2. The pressing block 5 and the flanging die 6 are both installed at the lower part of the upper die 7. The lower part of the lower workbench 2 is connected to the lower workbench gas spring 21. The workbench gas spring 21 is installed in the base 1, the step portion 22 processed on the right side of the lower workbench 2 corresponds to the cutting die 12, the waste hole 11 is processed below and on the base 1, the upper part of the pressure block 5 is connected to the pressure block gas spring 51, the elasticity of the pressure block gas spring 51 is greater than the lower workbench gas spring 21, the side pressure block 9 is installed on the left side of the slider 10 through the side pressure block gas spring 91, the cutting die 12 is fixed on the left side of the slider 10, the lower part of the slider 10 is slidably connected to the base 1 through the slide rail 102, and the slide rail 102 is provided with a return spring 103. The upper right part of the slider 10 is processed to form a slider inclined surface 101, and the right part of the upper die 7 is correspondingly installed with a driving block 8, and the lower part of the driving block 8 is processed with a driving inclined surface 81 that matches the slider inclined surface 101;
[0021] The workpiece 4 is placed on the lower workbench 2, and the pressing block 5 presses the workpiece 4 and the lower workbench 2 downward. The pressing block 5 cooperates with the first flanging die 3 to bend the left part of the workpiece 4 to form an upper flanging 41, and the second flanging die 6 cooperates with the lower workbench 2 to bend the right part of the workpiece 4 to form a lower flanging 42.
