Tube manipulation and pipe-bending subcontract business, T&T Tubecraft, has taken delivery of a new all-electric 130 mm diameter multi-stack CNC tube-bending machine from tube manipulation technology specialist, Unison. The machine is the third Unison tube bender to arrive at T&T Tubecraft, where it joins a 50 mm Unison Breeze machine and a 100 mm Unison Breeze multi-stack model that are in daily use at the company’s Woking-based facility.

“Of all our tube benders, the 100 mm Unison machine is easily the busiest,” says T&T Tubecraft managing director Ross Turner. “This is largely down to its user-friendly programming, fast tool changes, automatic set up, and uncompromising levels of accuracy and repeatability. Ironically, when we purchased the 100 mm Unison machine back in 2015, we didn’t have a vast amount of work for it. This quickly changed, however, as we gained the ability to take on new projects. The new 130 mm machine will increase our capability even further, both in terms of capacity and the ability to tender for an even greater range of projects. We expect it to be of particular interest to customers in the aerospace sector.”

The bigger brother of the Unison 100 mm multi-stack machine, the Unison 130 mm tube bender is particularly suited to exotic alloys such as titanium and Inconel, as well as Super-Duplex stainless steels. Able to push-bend tubes of up to 6.2 m in length when in standard mode, the machine also features a hitch-feed facility, whereby the carriage retracts by the length of the next feed, enabling the mandrel bending of tubes of up to 8.7 m long. As a result of this capability, T&T Tubecraft believes that, out of all UK tube manipulation subcontractors, it may provide the longest bending range.

The latest SafanDarley app, which is available in various languages, is now live. Featuring a modern look, the app functions very quickly and has a number of new features, such as the option to send results to a specified email address.

Notably, the existing app, the Send & Bend app and the E-Toolbox – consisting of E-Bend, E-Cut and the Q-calculation – are integrated in a single application, so that users have all the information together and can easily switch between each one.

The Send & Bend app is suitable for the facade cladding industry (which measures profiles on site for the metal shop), as well as other sectors that often work with templates. With the app, users can easily select the most common profiles and dimensions, and send directly from the construction site to the sheet-metal workshop.

SafanDarley’s E-Toolbox is an application for users who bend and cut sheet metal. This app also provides all kinds of information about SafanDarley and its products.

The toolbox comprises three types of tool, the first of which is E-Cut. This part in the app serves to calculate the maximum cutting capacity of guillotine shears for various materials.

Another tool within E-Toolbox is E-Bending. With this tool users can easily calculate the required pressing force of various materials and V-die sizes. The third tool is Q-Calculation, which is necessary for determining the optimum opening height and tool combinations.

Bison Machinery has added a Morgan Rushworth servo-electric press brake to its showroom stock.

The machine is now commissioned and set up for demonstrations, and will be of interest to users of hydraulic press brakes that want to save time and money by reducing energy consumption and maintenance, while increasing cycle times.

The recently introduced XPE servo-electric press brake from Morgan Rushworth brings many benefits to the table when compared with traditional hydraulic models, says the company. For instance, servo electric models save energy, require much less servicing and feature faster cycle times. Not only that, but they are quieter to operate and do not produce hazardous waste products such as used hydraulic oil.

A major benefit is that the XPE press brake only uses power when it is actually working, delivering up to 50% savings in electricity consumption.

Further advantages include: the use of an O-frame design that reduces deflection of the machine frame; no requirement for hydraulic oil, thus reducing hazardous waste output; cycle times are up to 30% faster than an equivalent hydraulic machine; quiet operation improves the working environment; only requires around 25% of the servicing compared with a hydraulic model; and produces much more even bending pressure across the width of the machine.

The XPE servo electric press brake features proven belt-drive technology for a long working life with low maintenance requirements. All models feature the high-specification ESA S675 widescreen control and a generous level of standard equipment, reports Morgan Rushworth.

Belgrave & Powell Ltd, a specialist engineering services group, has acquired assets, IP and goodwill from Addition Manufacturing Technologies Ltd based in Preston, UK.

Operating from the same facility in Walton Summit, Preston, the business will now trade under the name Addison Forming Technologies Ltd. Terms of the transaction were not disclosed.

Addition was a global supplier of tube-bending equipment and tooling to the aerospace, automotive and nuclear industries. With the acquisition, Addison Forming will continue to offer a comprehensive range of services and products to its customer base, alongside new solutions that include automation and robotics.

Paul Ward, a partner in Belgrave & Powell, will lead the company as part of Belgrave & Powell’s Machine Technology Group. He says: “Despite the uncertain economic climate we recognised the long-term value in this activity, the highly skilled workforce and the company’s reputation for quality and innovation. Our vision is to provide clients with unsurpassed service, quality and technology.

“We’re delighted with this acquisition as it’s a key advancement,” he adds. “It complements our existing specialist services companies, while simultaneously allowing us to accelerate our ambitions in terms of offering advanced automation and robotic solutions. The retained team have some of the world’s best skills in the field of tube bending, tooling design and automation and, with the support of the group, we will offer immediate benefit to historical and new customers requiring support in this specialist sector.”
Belgrave and Powell Ltd is a UK-based specialist engineering services group with activities including specialist machine-tool services, tooling manufacture and distribution, operating from facilities in Preston, Halifax and Tamworth. Businesses in the group include Weld UK, Dean Smith & Grace, GAC Rail, Techni-grind and Maydown International.

Russian boiler manufacturer Krasny Kotelshchik bends 90-m long tubes into membrane walls consisting of numerous 180° single bends.

Modern power-plant construction requires powerful machines that can bend challenging materials according to strict specifications. The large dimensions involved require particular structures in the bending process. Here, tube-bending machine manufacturer Schwarze-Robitec designed the CNC 60 DB Twin booster bending machine for the Russian company, complete with 90-m long tube magazine and supporting table featuring a 10 m radius. The machine was recently put into operation.

Modern power plants continuously supply the exact amount of electricity required to the grid. The higher the process temperatures, the higher the level of efficiency. Constantly starting up and shutting down the power plants leads to extreme fluctuations in temperature.

Boiler and power-plant manufacturers aim to maximise the surface area to ensure the highest level of heat transfer. Tubes therefore need to be bent in narrow radii and must fulfil strict tolerance specifications in terms of wall thinning and ovality.

Krasny Kotelshchik bends tube serpentines consisting of numerous 180° single bends in sequence. Each tube section alone is up to 10 m in length. As a result, the corresponding tube system cannot be rotated as a whole for each subsequent bend. Instead, the CNC 60 DB Twin booster bending machine supplied by Schwarze-Robitec bends in both directions using two bending heads. The bending head that is not required moves to the side under the tube system. For this reason, the machine is installed in a pit in the production hall.

Schwarze-Robitec has also set up a supporting table measuring 20 m in diameter above the pit and around the bending head. The tube system is laid out on the supporting table during the bending process. Krasny can thus avoid any unwanted deformations caused by the enormous weight of the tube systems.
