As a modern and innovative company, we take our production of high-quality technology very seriously, investing regularly in new machinery and plant so we can offer our customers the very best machining methods.
In 2011, we decided to expand our sheet metal bending unit. With the equipment we had at the time, we were able to bend sheets of up to 8 m in length. While this satisfied many of our customers, we were unable to cater to the growing demand for ultra-long bending work for sheets over 8 m long.
Our new press brake actually consists of two separate machines, which can be operated separately or in tandem, depending on the task in hand. This not only lets us bend and fold very large parts but also means we can respond very flexibly to production peaks in the 8 m and less segment.
Very few companies in the region can draw on such a broad spectrum of machining options in order to serve the sheet metal bending and laser cutting markets.
Benefits of large part production
The option of bending sheet metal parts up to 16 m in length offers us a number of advantages. Instead of making multiple small parts and then welding them together, the workpiece can simply be bent to shape along its entire finished total length. Avoiding weld seams saves on welding work, which has a direct effect on price and delivery lead times.
Introducing our XXL press brake
Tipping the scale at 290,000 kg and measuring 18.2 x 5 x 5.5 m, the EHT KB16000 is a real giant among press brakes. When used in tandem mode, its applied force of 25,000 kN permits the bending of metal sheets up to 16 m in length. The maximum thickness of the workpiece material depends on the exact material used. Sheet steel, for example, can be bent along the entire length of 16 m up to a material thickness of 25 mm.
All details at a glance:
- Press capacity: 25.000 kN
- Length: 16.100 mm
- Opening between stands: 7.050 mm
- Throat depth: 1.005 mm
To ensure we can handle even the most complex customer orders, we also use specialised tools and techniques in combination with the Variopress 1250. Detailed computer simulations beforehand can verify the feasibility of the process quickly and without requiring bending tests. Accordingly, please don’t hesitate to talk to our skilled employees about your specialised enquiries.
A process known as “gooseneck” tooling lets us bend sheets into sharp angles, since the tool’s shape delays collisions between workpiece and tool during bending, permitting the workpiece to be bent further than would be possible with a straight tool.
When shaping metal sheet into U-profiles with a flat back and legs of equal height, an ancillary plate is used. During the bending process, this is bent across the opposite side of the back, creating a greater distance between the tool and the legs in the subsequent work steps, and thus enabling the creation of otherwise impossible edge profiles. As a last step, the ancillary plate is ejected to create the straight back required.
