Developed
for continuous use
The Haeusler VRM 4-roll round bending machine was developed for “HEAVY DUTY” use. 365 days – 24 hours, the Haeusler VRM always does its job. In addition, the optimised bending geometry allows the smallest possible bending ends to be realised. The VRM bending machine is the result of more than 50 years of continuous development work. Coupled with the new patented Haeusler BENDtronic® control system, it is now the benchmark for 4-roll bending machines. Of course in proven Haeusler quality – Swiss made.
Highest torques
By using rotary drives with very high torques, we enable our customers to finish their products in just a few work steps and thus increase their productivity. In addition, all rotary drives are equipped with a fast-acting braking system as standard. This ensures precise and safe working.
Very high accuracy
Due to the special and patented arrangement of the side roller cylinders, the guideways could be more than doubled compared to other suppliers. As a result, the highest bending accuracies can be permanently achieved and wear reduced to a minimum.
Optimum roller material
HAEUSLER uses only the most suitable roller material for our bending machines. The material is forged at our partner forges as close as possible to the final contour and then finally machined. This ensures that the properties created by the forging process are optimally transferred to the finished roll. For our customers, this means maximised service life.
Perfect bending results
The optimised bending geometry of the HAEUSLER VRM enables the bending of the narrowest diameters with the smallest possible bending ends at the same time. In addition, this bending geometry has also been optimised for bending conical components.
Bending becomes child's play
The latest generation of HAEUSLER's patented BENDtronic 2.0 control with integrated artificial intelligence enables the operator to achieve perfect bending results right from the start.
Efficient bending
with the VRM 4-roll round bending machine
The VRM 4-roll round bending machine makes bending processes child’s play. This already starts with the alignment of the sheet at the outlet side roller: The sheet is automatically optimally aligned by the machine, which saves the use of lifting gear and auxiliary personnel. During the entire bending process, there is no idle movement of the workpiece due to the bending of both ends of the sheet in the same pass.
Also, 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 – the sheet therefore remains clamped between the upper and lower rolls during the entire bending process. The machine automatically adjusts the straight remaining cylinder end to the shortest possible dimension. This saves you work steps.
Safe drive thanks to 4 rollers
The drive of the VRM 4-roll round bending machine by upper and lower rolls offers enormous advantages during the bending process: Even when bending the thinnest sheets, the workpiece is optimally transported. The sheet is securely clamped between the top and bottom rollers – there is no chance of the sheet slipping on the rollers.
The fact that all four rollers are mounted on roller bearings means that there are no lubrication problems in the roller bearings. Therefore, no frictional power has to be dissipated in the form of heat, as is the case with plain bearings. So you don’t need to worry about any friction that may occur.
Centralised control
The operation of the VRM 4-roll round bending machine is also very efficient: the complete bending process can be operated by just one person via a central, mobile control panel. All control elements are brought together there. In addition, the bending machine can be operated and controlled from both sides – the control panel does not have to be left for this purpose.
Automation of the bending machine
The hydraulic system of the VRM sheet bending machine automatically regulates the speed compensation between the upper and lower rolls. This ensures that the two rollers always roll optimally on the sheet metal to be bent. At the same time, the pressure relief valves protect the machine from overload. Thus, the bottom roller lowers itself according to the sheet thickness even with double sheet entry.
In addition, an automatic pressure compensation system for the bottom roller is installed in the VRM 4-roller round bending machine. This means that the same pressures always prevail at both ends of the cylinder to be rounded and the cylinder diameter is thus the same at both ends – for an optimum result.
