Customized Universal Hydraulic 4 Roller Plate Rolling Machine

The four-roller plate rolling machine is the simplest and fastest equipment to operate, because it can pinch the plate between two central driving rollers, pre-bend the front edge, and roll the part body in one direction along the trailing edge at a time. During the coiling cycle, because the sheet is always squeezed, it is impossible to lose the position of the sheet, which makes the 4-roller the only machine that is fully suitable for NC or CNC control.

After years of extensive research and development, the 4-roller plate rolling machine has been regarded as one of the best plate rolling machines in the global market. The four-roller plate rolling machine is the simplest and fastest equipment to operate, because it can pinch the plate between two central driving rollers, pre-bend the front edge, and roll the part body in one direction along the trailing edge at a time. During the coiling cycle, because the sheet is always squeezed, it is impossible to lose the position of the sheet, which makes the 4-roller the only machine that is fully suitable for NC or CNC control.

When using a 4-roller rolling machine, one of the most important aspects is to be able to maintain the perfect parallelism of the lower center squeeze rolls. CHAOLI four-roller plate rolling machine has heavy linear structure and light lever arc structure. For the latter, CHAOLI light wire rolling mechanism, the lower roller is raised and lowered by rotating an eccentric rod located below the lower roller. Since both ends of the roller are lifted by this integral eccentric rod, it is impossible for the lower roller to move out of the parallel position. Other manufacturers are using a series of complex and expensive hydraulic circuits and multiple encoders to control the flow of oil to two independent cylinders to maintain theoretical parallelism. If any of these independent components fails, the ability to keep the rollers parallel will be lost. The parallelism of the side rolls is also maintained by the torsion bar system, which connects the two ends of the rollers together, again eliminating the need for additional encoders and hydraulic circuits with higher failure rates.
