1. Select the appropriate metal material as the raw material of the diversion ring, and design and manufacture the appropriate stamping die according to the design requirements of the diversion ring. The die usually includes an upper die and a lower die, which are used to punch metal materials into the shape of a diversion ring.
2. According to the required size for subsequent stamping, the metal material is cut into workpieces with appropriate size. Install the upper die and the lower die on the punch, and ensure the position and alignment of the dies.
3. Put the cut workpiece on the lower die, and press the upper die under the action of a punching machine to punch the workpiece into the shape of a diversion ring. In the stamping process, metal materials will be subjected to high pressure to form the required concave-convex shape.
4. After stamping, the diversion ring may need to be further shaped and corrected to ensure the accuracy of size and shape. Finally, the diversion ring may need surface treatment, such as spraying and chromium plating, to increase its corrosion resistance and aesthetics.
