Schwarze-Robitec GmbH
Precise bending under maximum load with the CNC 220 HD
Flexibility and precision – and that in large quantities: The demands placed on tube and pipe bending processes in the shipping and offshore industries are enormous. With the CNC 220 HD Schwarze-Robitec has now delivered a suitable solu- tion to the Norwegian company Framo. The manufacturer of pump solutions for cargo off- loading systems and oil and gas extraction processes now uses the reliable and highly robust tube and pipe bending machine for the fast and ef cient pro- duction of custom- t tube and pipe systems. Different tube geometries can be processed exibly using the correspond- ing bending tools. All necessary tool changes can be carried out quickly and easily with a new system. This results in reduced re tting times and a boost in productivity.
Framo, based in Bergen, Norway, has been a renowned manufac- turer of pump systems for more than 80 years – and is the market leader world-wide for cargo pumping systems. For the ship- building industry, tube and pipe bending machines that enable fast and very precise bending of complex tubes and pipes are in demand. This is because precision is an important prerequisite for the later assembly of the tube and pipe systems.
For processing tubes and pipes with larger diameters and made of high-strength duplex steel, Schwarze-Robitec has now
equipped Framo with a new CNC 220 HD: The tube and pro le cold bending machine is designed for permanent use under heavy loads, as it has a particularly high level of rigidity. It is ideal for absorbing extreme bending forces and thus prevents the machine body from twisting. The powerful and low-noise machine from the Heavy Duty series from Schwarze-Robitec processes tubes made of various materials, such as steel, copper/nickel/iron alloy and stainless steel. For Framo, the 30-ton machine bends tubes up to a diameter of 219 mm with a maximum wall thickness of 12 mm. Its speci c range of ser- vices even includes tubes with demanding dimensions, such as 208 x 4 mm and 168 x 14 duplex – Schwarze-Robitec individually responds to such customer-spe- ci c requirements with every order.
Armed for the future with special equipment
The ange tube equipment enables bending, anging on both sides of anged tubes and folded tubes with loose anges. This elimi- nates the need for subsequent anging of bent tubes and the bending process is optimized in terms of time and costs. With the help of an adapter and a gripping device, the individual tool com- ponents are connected to form a set. This allows the heavy tools to be changed quickly and ergonom- ically using a crane. The existing tools can also be ideally inte- grated into the system. Another
With the reliable and extremely robust CNC 220 HD tube and pro le cold bending machine, Framo quickly and ef ciently produces tube systems that t perfectly.
special feature of the CNC 220 HD supplied is the swing-out wiper die allowing for extremely short remaining lengths. The wiper die is swung out before the nal bend for a tube or pipe system so that the index head can move the tube extremely close to the bend former. This way, users achieve the shortest possible lengths for the nal bend – tube and pipe waste is signi cantly reduced, which effectively lowers produc- tion costs. The intuitively oper- ated CNC control of the tube and pipe bending machine enables safe and proactive remote main- tenance through simple access to all diagnostic functions.
