The roll forming machine is also known as a wheel rim forming machine, and is used for symmetrical or asymmetrical roll forming of steel wheel rims. The roll forming equipment consists of the main machine, hydraulic transmission system, pneumatic system, PC control system and lubrication system.
Generally, small rim lines and large rim lines carry out 3 processes to complete the rim profiling. Each process uses one set of roll forming machines. However, the ultra-large line completes the rim roll forming operation through 4 processes. The 4 thpresses the roll press into a non-skid pattern.

Main Features
1. The forming dies on this wheel rim roll former comes with an easy to dismount design which ensures a quick change of the die, controlling the changing process to take only about 30 minutes.
2. Both the small and large wheel rim lines often use 3 roll forming machines that share one set of automatic load and unload mechanisms. These systems use a 3 process and 4 location design, which saves time and improves production efficiency.
3. The split design between the load/unload unit and the main machine allows for both manual and automatic operations.
4. The roll forming dies can be designed to be symmetric or asymmetric according to processing demands.
5. The upper and lower shafts are hydraulic driven. During the rim profiling, the rotating speed of the upper and lower rollers can be automatically adjusted.
6. The shafts can be adjusted at both dip angles and axial directions. This makes each part of the roller surface uniformity stressed, ensuring the precision.
7. The space between the upper and lower spindle is adjustable, as is the feeding speed.
8. The stroke of a side guide rail is also adjustable.
