HDR 3-roll round bending machine│The ”genius“ among plate bending machines

High performance
Multiple possibilities

HDR 3-roll round 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 round 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 round 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 adjustment of the top roll over four identical cylinders, an absolute bending symmetry can be achieved - this is the basis for perfect bending results.

pointer

Highest accuracy

By using special T-slides in the drive and hinged bearing stand, the guideways are more than doubled compared to other suppliers. This allows the highest bending accuracies to be achieved on a permanent basis

pointer

Optimum roll material

HAEUSLER uses only the most suitable roll 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 produced by the forging process are optimally transferred to the finished roll. For our customers, this means maximizing of components life time.

pointer

Highest torques

By using rotary drives with very high torques, we enable our customers to finish their products in just a few passes, thereby increasing their productivity. In addition, all rotary drives are equipped with a fast reacting brake system as standard. This ensures precise and safe operation.

pointer

Easy maintenance

All main cylinders of the machine can be reached in a few easy steps and guarantee easy and quick maintenance.

Easy to operate

The menu navigation on the touch screen control is intuitive, the machine actively supports you in operation. All bending relevant data can be displayed and adapted on the control system.

Specific features
of the HDR 3-roll round 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 plate 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 a 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. The HDR 3-roll round bending machine has numerous other advantages to offer in addition to these aspects. This sets it apart from other 3-roll bending machines on the market in many areas.

Benefits compared to other 3-roll bending machines

The HAEUSLER HDR bending machine differs in many aspects from other 3-roll bending machines on the market. For example, the symmetrical design of the HDR ensures accurate and optimal bending results. In machines with an asymmetrical design, it proves difficult to achieve a good bending result. Also, the four used and identical pressure cylinders of the HDR bending machine provide considerable advantages, such as highly accurate synchronisation, compared to outdated designs of competitors.
