LVD has introduced its Synchro-Form adaptive bending technology. Synchro-Form automatically maintains angular consistency and the required geometric profile when handling, positioning and bending large parts with multiple bends, says the company, thus overcoming the problems of accumulative error and trial-and-error bending.

Synchro-Form uses a laser scanner and synchro modules to manipulate, position and measure each bend, relaying the digital information to the Touch-B control, which makes adjustments to part and ram position to achieve the correct profile. Variations are not accumulated but, instead, compensated with each bend step. According to LVD, even after multiple consecutive bends, the profile will be perfectly formed.
The system is an integrated feature of the company’s Synchro-Form series press brakes in models ranging from 320 tons by 4 m, up to 3000 tons by 14 m. It is also available in tandem, triple and quadruple configurations.

According to Gasparini, mass production can now turn flexible thanks to the introduction of its latest smart press brake, which connects to the rest of the factory. The machine’s circuits, its frame, and its key components are populated with sensors in order to extract a wealth of data. This kind of forming line represents the very first press brake compliant with Industry 4.0, says the company.

The machine makes it possible to get detailed statistics about all production phases, as well as the cycle time needed to make a specific product. As a result, users can know actual costs, eliminate bottlenecks and monitor errors or other process-related problems. Another advantage of this network of sensors is the potential to detect problematic working conditions, and address them with preventive maintenance. Faults and machine stops can therefore be reduced, solving failures before they become production outages.
Sensors also allow the material being bent to be parameterised, keeping dimensional and strength variation under control. Furthermore, the machine will manage spring-back accurately and in real time, minimising the need for samples and tests.
Another novel feature is integration with other elements of a ‘smart factory’. Different from machines of previous generations, this automated bending line can be interfaced with ERP, NAS, CAD and CAM systems. Users can perform remote uploads of bending programs and drawings. The press brake can be connected to laser cutters, automatic warehouses, welding lines and so on.
Gasparini will be showcasing its new automated bending line during an open house this week (12-13 May).

To increase the company’s bending capacity and further improve its capabilities, Kings Lynn-based Dale Sheetmetal, recently purchased a Prima Power servo-electric press brake. Although smaller versions of Prima Power’s eP series have previously been installed in the UK, the large eP 1336 variant, with 135 tonne press tonnage and bending length of 3655 mm, is the first of its kind installed in the UK.

Explaining the purchase, managing director Dave Dale says: “Each stage in our company’s development has been driven by growing customer demand. Having identified bespoke bending as a pinch-point, we recently investigated the latest press brake technologies. Rather than investing in a conventional hydraulic press, in accordance with our philosophy of installing the best available technology, we only looked at next-generation, all-electric machines. Although a couple of alternative options would have provided many of the qualities we were seeking, Prima Power’s eP 1336 proved to be the ideal machine for our needs.
“Now installed and fully operational, the speed and precision of the eP 1336 ensures that it produces high levels of consistently high quality work,” he adds. “In addition to satisfying existing customers’ needs, the high-quality features and the extra capacity created by our Prima Power servo-electronic press brake will allow us to enter new markets.”
The eP 1336 range uses a pulley-belt system that is actuated by Prima Electro servo drives, distributing the bending force over the whole bending length. It consists of fixed and moving rolls spread out over the working length of the upper beam. The belt itself has a steel wire reinforced, maintenance-free construction.

With a new order underway for a customer in Dubai following success in supplying distributors across Europe, GRP Tools, a specialist producer of glass-fibre applicators and ancillaries to the trade, is well on its way to making 1500 rollers a day.

The hand-roller applicators form the bulk of the Totton-based company’s business. From steel wire feedstock, roller wires are cut and bent into the required shape. Before automating the wire bending and handle assembly operation, several staff were employed on manual, single-operation, wire-bending and crimping activities.
To address the situation, managing director Peter Hussey turned to the technical solutions of Whitelegg Machines, which offered great flexibility in wire sizes and lengths, speed of operation and rapid changeover, including intuitive touch-screen control.
The selected machine, designated the PRL-8, is loaded with previously cut wires of appropriate length. A single wire is released into the nibbing station where two hydraulic units form the handle nib and a second nib as required. The pick and place unit then removes the wire, indexes the blank and loads it into the bending head. Here it is clamped and the head forms the bend nearest to the handle; it then indexes, retracting to position to form the second bend. At this point, the handle is clamped and the third bend is formed.
The formed component is then moved to the handle inserter where a plastic handle has been collected from the magazine by the handle pick and place. The handle inserter pushes the plastic handle on to the wire frame, which is then removed from and dropped into the unload chute; the cycle time being 5-7 seconds.
