Plate bending machines

The lateral support is used to support workpieces with a relatively small wall thickness in relation to the diameter. Depending on the requirements, the lateral support is equipped with one or two support rollers. The required support force depends on the sheet dimension.

The cone bending device enables cone bending of workpieces in the roll bending process. The cone bending device ensures that the workpiece is ideally positioned during the bending process.

This option enables the use of smaller top rollers to achieve correspondingly smaller bending diameters. Interchangeable rollers can be ordered in different diameters as an option.

The roller change carriage is used to change the various top rollers quickly and easily. Instead of simply using a crane, the top roller is pulled out of the storage system or inserted by a carriage placed on the side rollers. This greatly simplifies the process of changing the rollers.

This option is useful if you often switch between normal and stainless steel in production. When bending, there is always an exchange of material between the rollers and the workpiece. This is problematic when changing from normal to stainless steel, as these normal steel particles lead to corrosion in stainless steel. The hardened roller surface greatly reduces the indentation of plate material and simplifies cleaning of the rollers.

In order to compensate for the deflection of the rollers during bending, crowning is applied to the bottom and top rollers. This can lead to unwanted deformation, especially with thin-walled workpieces. By increasing the diameter of the bottom and top roll, the crowning can be reduced and the application range of the machine in the lower sheet thickness range can be extended.

Cycle times, particularly when calibrating or bending large diameters, are influenced by the rotation speed of the rollers and not, as with other bending operations, by the level of torque installed. HAEUSLER therefore offers the option of increasing the rotation speed to 8 m/min (this option is included as standard on EVO machines).

The air/oil cooler replaces the water cooling system installed as standard and cools the hydraulic oil in the hydraulic unit without the use of cooling water. This option is only practical at ambient temperatures <40°C. (On EVO machines, this option is included as standard).

For ambient temperatures >40°C, the standard air/oil cooler can no longer be used. In these cases, a chiller is used to cool the hydraulic oil. The closed cooling circuit can save a lot of cooling water.

During calibration, the workpiece rotates in the bending machine with the rollers stopped, and the weld seam is also traversed. The gas pressure accumulator ensures that the resulting force peaks are eliminated and thus protects the roller bearings against overload.

In order to be able to process the much thicker sheets during hot bending, the throughput of the machine is significantly increased. This requires larger machine columns and cylinders with more stroke. Furthermore, the thermal radiation of a red-hot sheet requires additional modifications to the machine in order to ensure trouble-free operation under these extreme conditions.

During hot bending, the workpieces lose heat very quickly through contact with the cooler rollers. The rollers can be preheated by an arrangement of gas burners, thus reducing the heat loss.

The infeed table is used to feed the workpiece into the bending machine safely and efficiently. Mittels optionaler Blechzentriereinheit wird das Werkstück dabei automatisch zentriert. The sheet alignment device can consist of several centring units that are integrated into the infeed table.

HAEUSLER offers special solutions for the series production of conical workpieces that significantly simplify and speed up production processes. These include the workpiece manipulator I. The sheet metal is positioned and held in place by independently adjustable positioning rollers. The WM-I is attached directly to the infeed table and can therefore only be ordered in conjunction with it.

The workpiece manipulators II and III are mounted on special lateral supports. During the bending of normal cylinders, WM-II and WM-III take over the function of normal lateral supports. During cone bending, they allow the workpieces to be guided continuously and thus enable faster and more precise work. This option replaces the lateral support option.

The roundness measuring system is used to determine the roundness of workpieces efficiently and with high precision. For this purpose, two industrial lasers are used to continuously scan the inner lateral surface (and the outer lateral surface for small diameters) of the workpiece. This allows the roundness to be displayed graphically over 360° and can also be targeted for correction.

By means of a hydraulically operated lateral alignment unit, which is located close to the side roller, lateral axial offset of the workpiece ends can be eliminated in the machine before tack welding.

Hydraulic clamping device that uses a cylinder to correct any radial misalignment of the workpiece ends. For easy handling of the clamping device, it is mounted on a swivelling crane, which is attached to the drive stand of the bending machine.

Hydraulically adjustable for precise positioning of the sheet metal when bending cylindrical parts.

The upgrade to CNC functions increases the machine’s production flexibility and reliability. The CNC function enables work programmes to be generated and saved.

HAEUSLER’s revolutionary BENDtronic® enables anyone to control not only the movements of the machine but also the bending result itself. The software is graphically supported and allows bending in one or more passes. It can also be used for any type of product shape such as cylinders and tubes, ovals, tanks or other more complex geometries up to S-shaped workpieces. The BENDtronic® contains various auxiliary tools which provide the operator with optimum support during bending (on EVO machines this option is included as standard).

The cone bending device enables cone bending of workpieces in the roll bending process. The cone bending device ensures that the workpiece is ideally positioned during the bending process.

This option allows the use of smaller top rolls to achieve correspondingly smaller bending diameters. Exchange rolls can be ordered in different diameters as an option.

This option is useful if there is a frequent change between normal and stainless steel in production. During bending, there is always an exchange of material between rollers and workpiece. This is problematic when changing from normal to stainless steel, as these normal steel particles lead to corrosion in stainless steel. Due to the hardened roll surface, the indentation of plate material is greatly reduced and cleaning of the rolls is simplified.

For ambient temperatures >40°C the standard air oil cooler is no longer usable. In these cases a chiller is used to cool the hydraulic oil. A great deal of cooling water can be saved due to the closed cooling circuit.

During calibration, the workpiece rotates in the bending machine with the rollers set, and the weld seam is also traversed. The gas pressure accumulator ensures that the resulting force peaks are eliminated and thus protects the roll bearings against overload.

In order to be able to process the considerably thicker sheets during hot bending, the machine’s throughput is increased considerably. This requires larger machine stands and cylinders with more stroke. In addition, the thermal radiation of a red-hot plate necessitates additional modifications to the machine to ensure trouble-free operation under these extreme conditions.

The infeed table is used for safe and efficient feeding of the workpiece into the bending machine. The workpiece is automatically centred by an optional sheet centring unit. The sheet alignment device can consist of several centering units which are integrated into the infeed table.

The roundness measuring system is used for efficient and highly precise determination of the roundness of workpieces. For this purpose, two industrial lasers are used to continuously scan the inner surface of the workpiece (or the outer surface for small diameters). This allows the roundness to be graphically displayed over 360° and can also be targeted for correction.

Hydraulic clamping device, which corrects a possible radial offset of the workpiece ends with the help of a cylinder. For easy handling the clamping device is mounted on a slewing crane, which is fixed on the drive stand of the bending machine.
