Rim Roller Machine​

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.

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. Technical specs
