The rim roller machine is intended for rim processing. Rim rolling usually involves three processes, each of which requires a rim roller machine consisting of the main machine, hydraulic system, PLC control system, loading and unloading device and rim roller tooling.

Process drawings
  • 1st roll forming
  • 2nd roll forming
  • 3rd roll forming
  • 4th roll forming for non-skid pattern
Features
  • The easy-to-disassemble design, with an optional fast die-changing mechanism, helps to effectively control the changing time within 30min.
  • Both small and large wheel rim production lines use 3 rim roller machines for different roll forming processes. The 3 roller machines share one set of automatic loading and unloading mechanisms to achieve automatic operation.
  • With a 3 process and 4-station design, it allows for simultaneous loading and unloading in all 3 processes to save time and improve productivity.
  • The loading and unloading mechanism is connected to the main machine in a split design. The manually operated production line can be disassembled for changeover between manual operation and automatic operation.
  • The roll forming die can be customized to be symmetric or asymmetric according to customer machining requirements.
  • Upper and lower spindles are hydraulic driven. The speed of upper and lower forming rolls can be automatically adjusted during the roll forming process.
  • The spindle is adjustable in dip angle and axial direction to ensure each part of the roll forming die surface features consistent stress and ensures the processing accuracy.
  • Space between upper and lower spindles can be adjusted, as well as the feeding speed.
  • The stroke of side guide roller is also adjustable.
