The VRM 4-roll circular bending machine makes bending processes child’s play. This already begins with the alignment of the sheet on the roller on the exit side: the machine automatically aligns the sheet optimally, saving the use of lifting means and auxiliary personnel. During the entire bending process, there is no idle movement of the workpiece due to bending of both ends of the sheet metal in a single pass.
Additionally, the VRM bending machine does not require the sheet to be aligned twice, as is the case with 3-roll machines, due to the automatic bending of the second end of the sheet, so the sheet is clamped between the upper and lower rollers. throughout the bending process. The machine automatically adjusts the remaining straight end of the cylinder to the shortest possible dimension. This saves you work steps
Bending machine automation
The hydraulic system of the VRM sheet metal bending machine automatically regulates the speed compensation between the upper and lower rollers. This ensures that the two rollers always rotate optimally on the sheet to be bent. At the same time, pressure relief valves protect the machine against overloads. In this way, the lower roller descends according to the thickness of the sheet, even in case of double entry of the same.
