[0035] The working process of the present utility model is as follows: First, the workpiece to be flanged is sleeved on the outer wall of the positioning cylinder 3. The screw rod 4 can be driven to rotate by the second servo motor 10. The rotation of the screw rod 4 drives the moving ring 5 to perform a lifting motion.

The threaded rod 12 is driven to rotate by the third servo motor 14. The rotation of the threaded rod 12 drives the moving block 13 to perform a translational motion. The movement of the moving block 13 drives the telescopic cylinder 15 to perform a translational motion. The telescopic cylinder 15 drives the connecting block 16 to perform a lifting motion, thereby adjusting the positions of the flanging press wheels 18 and the flanging rotating wheels 19 on both sides to match workpieces of different sizes. When the workpiece is flanged by the flanging machine, the flanging rotating wheel 19 is fixed, while the flanging press wheel 18 can move. By moving the flanging press wheel 18 outward, the edge of the workpiece is bent into the required shape to achieve the flanging treatment. The above is the working principle of the equal-diameter flanging machine that is convenient for positioning.
