The forming device 400 is disposed on the discharging side of the drawing device 300, and is configured to bend the rolled alloy rod/wire to a certain extent, so as to facilitate subsequent winding of the alloy rod/wire onto the rod winding device 500. The forming device 400 is arranged to pre-bend the rolled alloy rods/wires, so that the cold rolling and rolling system is more suitable for rolling high-strength alloy materials.

And the rod winding device 500 is arranged on the discharge side of the forming device 400 and is used for winding the bent alloy rods/wires into rings so as to facilitate subsequent processing, transportation and storage.

The initial alloy rod/wire is rolled in corresponding rolling passes to reach the diameter size required by the next procedure. For example, the tensile strength of the initial alloy copper rod can reach 200-260MPA, care needs to be taken when the compression ratio is selected, the alloy copper rod can crack due to larger deformation amount, the quality of a rolled product is affected, and the cracking in the cold rolling process can be effectively avoided by selecting a small compression ratio between 1.0 and 1.2.
