PRV 4-roll profile bending machine│3-D Profile bending in perfection

At the beginning of this millennium HAEUSLER developed this machine type for the Russian aerospace industry. Continuously developed, this type of machine is now used worldwide. The special feature of these profile bending machines is the free adjustment of the lateral distances of the bending rollers. This allows the operator to form any highly complex profile with ideal force application in order to minimize unwanted deformations or to generate large bending moments.

The PRV 4-roll profile bending machine from HAEUSLER enables a flexible adjustment to different profile types and material thicknesses thanks to its variable geometry of the side bending rolls. This allows for optimal control of the bending process and adaptation to specific requirements.
A large distance between the side bending rolls reduces the required bending forces by distributing the force application over a larger area. This setting is particularly suitable for bending large or massive profiles, as the material undergoes less mechanical stress during deformation. As a result, unwanted material stresses are minimized, and a uniform bending process is ensured.
A small distance between the side bending rolls allows for precise guidance of the profile and improved control over the springback behavior of high-quality materials. This ensures minimal straight ends, which is especially important when tight tolerances are required. The increased force application to a smaller area enables accurate shaping and reduces elastic effects that could lead to undesired deformations. Thanks to these features, the 4-roll profile bending machine offers high flexibility for various bending applications and ensures repeatable, high-precision results.
