Ursviken is currently amid its largest project yet: building a custom press brake with a bending length of 22.2 m and press force of 5000 T. Once complete, the company says it will be the largest press brake ever built in the industry, breaking its own record from 2021 when Ursviken built a press brake with a bending length 20.8 m. 

As of now, the manufacturing process is well underway, with delivery estimated at some point this autumn. The main challenges thus far related directly to the size of the machine.

“The first challenge our engineers had to tackle was creating a design capable of withstanding the press beam weight of nearly 400 T,” explains Martin Edeljung, production manager at Ursviken Technology.

On the manufacturing front, the handling of heavy components, including raw material that is up to 320 mm thick and weighing over 1000 T in total, presented its own set of challenges. The transportation of these pieces to and within the factory during various production phases, from cutting to welding and milling, required careful manoeuvring due to their size and weight.  

Looking ahead, Ursviken can still expect to face challenges in the planning and final assembly stages.

“Given the unique nature of this machine, everything must be tailor-made, adding complexity to the assembly process,” says Edeljung. “The disassembly, transportation of the finished machine in parts, and on-site assembly, will require meticulous planning and co-ordination.”

For those in the business of fabricating server cabinets, NEMA boxes or switchgear cabinets, precision, efficiency and flexibility are non-negotiable. The team at RAS Systems understands these demands and offers tailored solutions to address these challenges.

One of the biggest challenges in this industry is manoeuvring large and heavy profiles. Traditional forming systems like press brakes often fall short, making the process cumbersome and time-consuming. The RAS UpDownCenter-2 addresses this issue with its material handling capabilities, including automatic up and down folding sequences, and the PosLift part positioning system. These features minimise manual intervention, ensuring the handling of even the heaviest parts with precision and ease, says the company.

Multiple tooling changeovers coupled with tired and inexperienced operators often lead to inefficiencies and increased labour costs. The UpDownCenter-2’s automatic tool changer and one-click programming software reduce set-up times and enhance productivity, especially in jobs with small batch sizes. According to RAS, the automation ensures consistent quality and precision, reducing human error and ensuring high-quality outcomes.

Customers frequently request unique and complex designs, requiring a high level of flexibility in production. The UpDownCenter-2 excels in this area, reports RAS, accommodating both small and large batch sizes. Its ability to bend parts with embosses, large holes and oblique base shapes makes it suitable for custom designs. One-click programming further streamlines the set-up process, making it easy to switch between different production runs quickly and efficiently.

Processing various materials, such as milled steel, aluminium and stainless steel, is another industry challenge. The UpDownCenter-2 can handle a variety of material thicknesses. This capability ensures precision and consistent quality across different material types, making it a versatile solution for diverse production needs.

LVD has introduced Easy-Cell 80/25, the latest in its line of robotic bending cells for automated bending. Easy-Cell offers high flexibility to produce a wide range of parts with the precision of a built-in adaptive bending system, which the company says ensures bend angle accuracy from the first part. The robotic bending cell incorporates LVD’s software for fast, simple offline programming of both press brake and robot. According to the company, users benefit from the productivity of automated bending with high process reliability and low component costs.

Easy-Cell 80/25 combines an Easy-Form 80 T press brake with a Kuka industrial robot to handle parts from 100 x 100 mm up to 1600 x 1200 mm, weighing up to 25 kg. The press brake features a 2500 mm bend length, five-axis back-gauge, and 2500 mm crowning table, providing the versatility to accommodate a broad scope of bending applications.

Notably, the cell features multiple robot grippers that offer easy changing to suit the job in hand. The robot uses a proprietary swivel function to optimise workpiece regripping. This swivel movement reduces the time it takes for re-gripping, improving overall cycle time.

Easy-Cell features LVD’s Easy-Form Laser for bend accuracy. Automation with built-in quality assurance provides a high degree of consistency in production, especially critical for automated operations.

Easy-Form Laser uses adaptive, in-process control over the bend angle. The system compensates for material variations such as sheet thickness, strain hardening and grain direction. Scanners continuously measure the bend angle and transmit information in real time to the CNC control for immediate adjustment of the punch position to achieve the correct angle. The bending process is continuous and no production time is lost.
