HDR 3-Roll Plate Bending Machine│The Universal Sheet Metal Bending Counter
High performance Multiple possibilities
HDR 3-plate bending machine
A machine as flexible as is its variable geometry
First-class HAEUSLER quality and expertise paired with durability and low operating costs – this is exactly what you get with the 3-roll plate bending machine HDR from HAEUSLER. The HDR convinces by the individually adjustable bending geometry of the bottom rolls, which enables rolling of very thick plates as well as small diameters. Best bending results can be achieved thanks to the use of the patented top roll adjustment by using only pressure loaded cylinders and thus resulting machine symmetry.

Power development mit sensitively
There a different designs of 3-roll bending machines, where the most advanced design is characterized by its variable adjustment of the rolls. Following this variable machine geometry the HAEUSLER HDR allows linear adjustment of the 2 bottom rolls independently from each other, while the top roll can be adjusted vertically. All 3 rolls can be driven, inclined roll setting enables cone bending. This design principle offers, compared to all other 3-roll machines, significant advantages regarding minimization of flat ends, best bending quality and workpiece handling. In addition, the HDR system is the only concept where the bending geometry can be set variably. This means that the deformable wall thicknesses can be adjusted according to the position of the bottom rolls within the performance range of the machine. The smaller the asymmetry of the bottom rolls to the top roll, the greater the possible wall thicknesses by accepting longer flat ends. The maximum deformable wall thickness is obtained with symmetrical position of the bottom rolls. Due to this functional principle, even the thickest plates can be bent with relatively low forces and thus extremely economically.
Best bending results
Due to the patented infeed of the top roller via four identical cylinders, absolute bending symmetry can be achieved – this is the basis for perfect bending results.
Highest accuracy
By using special T-slides in the drive and folding bearing stand, the guideways could be more than doubled compared to other suppliers. As a result, the highest bending accuracies can be achieved on a permanent basis.
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.
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.
Easy maintenance
All main cylinders of the machine can be reached in a few simple steps and guarantee easy and quick maintenance.
Easy to use
The menu navigation on the touch display is intuitive, the machine actively supports you during operation. All bending-relevant data can be displayed and adapted on the control.
Specific features of the HDR 3-roll sheet bending machine
The unique design features of the HDR 3-roll round bending machine contribute to the high quality and long service life of the machine. Even the base frame offers maximum stability under the bending forces exerted and consists of a compact, closed design. The rollers of the round bending machine are also manufactured to be extremely stable: The high-alloy and non-surface-hardened steels prevent cracks on the rollers. The rollers are driven by a high-quality 3-roller drive, which enables precise panel handling and high traction.
Additional advantages of the new design
Since the bearings and frame of the new HAEUSLER HDR design are absolutely symmetrical, the bending machine ensures high bending quality. In addition, the movements of the top roller are realised by two times two identical cylinders, which in turn are 100 percent symmetrical. This results in high bending accuracy during the bending process. In addition to these aspects, the HDR 3-roll round bending machine has numerous other advantages to offer. This sets it apart from other 3-roll bending machines on the market in many areas.
Advantages compared to other 3-roll bending machines
The HAEUSLER HDR bending machine differs in many ways from other 3-roll bending machines on the market. For example, the symmetrical design of the HDR ensures accurate and optimal bending results. It is difficult to achieve a good bending result on machines with an asymmetrical design. Also, the four used and identical pressure cylinders of the HDR bending machine offer considerable advantages compared to outdated designs of competitors, such as highly accurate synchronisation.

Standard equipment
Automatic central grease lubrication for easy maintenance
By using an automatic central grease lubrication system, all relevant points of the machine are automatically lubricated.
Fast reacting overrun brake for precise bending
The quick-reacting overrun brakes fitted as standard enable the operators to work very precisely. Furthermore, these brakes are an important safety factor, as they prevent plates from slipping out of the machine unintentionally.
Ethernet connection for online access
The online access enables our service engineers to access our customers’ roll bending machine within the shortest possible time and to ensure optimum support.
Optional equipment
Change rolls for bending small diameters
Exchangeable rolls enable our customers to bend even very small diameters. HAEUSLER machines are equipped in such a way that the roll in use is automatically recognized and the operating pressure is regulated accordingly.
Plate stops for plate positioning
The optionally available plate stop simplifies the alignment of the plate in the machine, is time saving and helps to achieve best bending results. Faster rotation for increased productivity
Faster rotation for increased productivity
Especially when bending very large diameters, the speed of rotation of the machine is decisive for productivity. For this reason HAEUSLER machines can be equipped with an increased rotational speed of up to 8m/min.
Optional accessories
Upper support for simplified bending of large diameters
Upper supports simplify the bending of large diameters, as the weft to be bent can be held and supported at 12 o’clock position during the bending process.
Lateral support for simplified bending of large diameters
Side supports can be fitted on both sides of the machine to assist the operator when bending large diameters.
Infeed roller table for quick and easy feeding of the plates into the machine
Infeed roller tables (optionally also with centring device) simplify loading the machine. Sheets are placed on the roller table and transported from there into the round bending machine.
