Made in Switzerland machines for accurate and fast production by Stierli Beiger AG company
hp’s frame bending machine is designed for bending profiles for ship’s frames. As well as HP ship’s frames (HP profiles, Holland profiles or bulb flats), other profiles such as L and T profiles can be bent. The ship’s frames can be bent individually or in pairs. The direction of machining (S bends) can be switched without changing the bending tools. The bending process can be carried out quickly and precisely. The operator is assisted by the straightforward NC+ control system with fine stroke adjustment. Up to 200 bending and straightening programs can be created, in which the movements of powered support rollers can be programmed. In automatic mode, ship’s profiles can therefore be processed economically.
The universal ship’s frame bending machine can be used for the following bending and straightening work
|Usage/Application||Rotator for Rail Production|
Steel profiles and beams can be cambered efficiently with the Stierli bending press. The profile is bent at regular intervals to create the pre-tensioning or camber of the steel beam required.
When it comes to structural pre-tensioning of steel profiles, the Stierli straightening press has the advantage over 3-roller bending machines that pre-tensioning is significantly more cost-effective with the Stierli press.
For mechanical pre-tensioning of an HEM 1000 beam, a very large, expensive 3-roller straightening machine would be required. The same process can be carried out significantly more cost-effectively with a Stierli bending pre
Steel beams and steel profiles are cambered for structural or aesthetic reasons.
The Stierli-Bieger bending machine completes this process of cambering steel beams efficiently and precisely. Stierli-Bieger has a wide range of machine models with various control systems. The typical working force of a bending press for cambering steel beams is between 220 and 440 metric tonnes. For special work involving cambering steel beams, we make bending presses with a working force of up to 900 tonnes.
3 different control system variants are available.
With Stierli bending and straightening presses, it is possible to pre-tension heavy bridge girders. We build machines up to 900 metric tonnes. These enable pre-tensioning of heavy HL-R 1100 girders
Cambering of steel beams requires a certain amount of experience. We provide additional support by using a laser system, which assists with the control of the bending process.
In the case of CNC control, the control system controls the straightening cylinder completely. The operator needs only to enter the required camber and the length of the profile.
Using the values measured with the laser system, the feed values are calculated and the spring-back effect of the steel beam is compensated for.

The laser measuring system can also be used for the machines with NC-control as a visual control for profiles and beams. The Deformation will be indicated digitaly.
