[0001] The utility model relates to the field of metal plate forming and processing, in particular to a pair of circular ring rapid forming pliers. Background Art

[0002] There are generally three methods for making rings from sheet metal: extrusion molding, roll bending, and manual bending. Large pieces are generally made by roll bending, while small pieces produced in batches are mostly extruded by molds. However, the production of some small batches of small-piece rings is not suitable for roll bending, as the cost is too high if molds are used, and manual bending is inefficient and has uneven quality.
