Square Tubing Bender – PBT profile bending technology

PBT can bend it all from square tubing to specialize profiles

Bending tubes and profiles of various types is a normal part of the production processes of many industries. Complex bending tasks require equally tailored and sequenced bend measures and processes. Vehicle construction, materials handling, metal construction and aerospace are among the sectors demanding complex tube bending machines. For more than 25 years, PBT has developed the expertise and technology to offer a range of profile bending machines, along with specialized expansions, tooling and services to support this varied demand.

The advantages of a PBT square tubing bender

The modular design of PBT's line of machines can be equipped with various additional devices and extensions to further expand the foundational performance spectrum. It's specialty mandrel bending device, compatible with every three-roll bending machine, is designed to support the process of bending especially thin-walled square tubes. With PBT's PC400 control, operators can take bends that go far beyond manual operation. This means that even complex molds can be produced with demanding material - without the need for expert programming knowledge.

Precise bending machine for edge profiles

PBT's profile bending machines and controls are among the best in the industry. Each of its models produce precise radii and repeat accuracy for square tubing minimizing batch-related deviation:

- ARKUS12 pipe bending machine: As the most compact of the profile bending machines, the ARKUS12 is ideal for bending smaller profiles made of steel or aluminium, especially where space is rather limited. Thanks to an option for reducing the roller distance, even profiles with the smallest radii (> R35 mm) can be bent into larger radii without kinks. The bending unit can be moved to the desired location by means of a lift truck. The possible controls are manual or digital via tablet.

- BENDO pipe bending machine: High performance, excellent quality and ease of use are combined with the BENDO profile bending machine. A minimum front roller distance of 280 mm also results in the smallest radii with clean transitions, and transport with the help of a lift truck is also possible. Thanks to the larger and more powerful design, this model is particularly suitable for industry, job shops and series production processes. It can be operated manually, with a Tablet350 or the PC400.

- PBT25 pipe bending machine: A special feature of the PBT25 pipe bending machine is its modular design, which enables quick and flexible conversion according to individual work processes (rolling, bending, folding). In addition, the 300 mm high drive rollers allow the insertion of relatively wide square tubing. The distance between the front roller can be reduced to just 200 mm. Despite this power density, the unit is sufficiently compact and can be transported with pallet trucks or similar, and control is also possible both manually and digitally.

- PBT35 Servo tube bender: The PBT35 Servo is similar to the PBT25 in some respects, but has been specially developed for higher power. This is due to the servo drive for all three rollers, which sets this tube bending machine apart from the usual hydraulic models. The minimum distance of the front roller is 360 mm, which influences the possible radii. In addition, the higher capacity of the machine and the associated dimensions mean that it has to be transported by forklift or crane. The PC400 software is used for control.

- HELIX Servo pipe bending machine: When it comes to the precise bending of the largest profiles, for example for support elements in architecture, the HELIX Servo is used. According to this application, the minimum front roller distance here is 630 mm. As a powerhouse among the tube bending machines for square tubing, it nevertheless offers the highest accuracy down to 1/100 mm. This is achieved not least by the economical but powerful servo drive and the PC400 control system. At 5500 kg, the HELIX is more than twice as heavy as the next smaller PBT35 and therefore also requires a crane for transport and placement.
