According to the diameter of the circular metal parts, an appropriate number of assembly circular frames 22 can be selected and installed. The thickness of each assembly circular frame 22 is one centimeter. By installing an appropriate number of assembly circular frames 22, the circular metal parts can be limited, so that the circular metal parts with different diameters can be curled. When the curling operation is performed, the hydraulic cylinder 7 drives the stamping disc 8 to press down, so that the stamping disc 8 presses the placed circular metal parts into the inside of the curling circular mouth 12, and bends the part larger than the diameter of the stamping disc 8. The bent edge part is curled into a ring-shaped vertical state along the stamping disc 8, and passes through the curling circular mouth 12 together with the circular metal parts and falls into the inside of the forming groove 16. Finally, the electric push rod 4 drives the lifting platform 3 to move downward, and then pulls the handle 17 to pull the pull-out carrier 15 out of the assembly slot 14, and takes out the curled circular metal parts in the forming groove 16, completing the use of the circular metal part curling device.
