Southwest Manufacturing News • April 21 • Reliability and Durability are the Priority

transfluid, developer and producer of machines to bend and process tubes, has updated its K series of machines. All the machines in this series can now be controlled easily with a touch panel. “This opens up new possibilities, like displaying the comparison of target and actual values for all axes,” said a company spokesperson. “Control of the tolerance of the length and the rotation means very little involvement by the operator during the manufacturing of tubes. The options have also been improved by the possibility of loading the bending data for individual products from a PC via a USB port.”

The machines are designed to be robust and easy to operate. A selection of set-ups are available to process tubes of different lengths, with an operational length from 1,500 mm to 3,000 mm, 4,500 mm and up to 6,000 mm. “We have again improved the areas of excellence of our K series,” explained Stefanie Flaeper, Managing Director of Sales. “One example is the DK 642K bending machine with mandrel. Its specific area of application is hydraulics.”

The machines have equipment available, like an integrated saw, a burring device, a tool for cutting ring pre-assembly or one for flaring. The area of excellence covers all standard diameters (from 6 mm to 42 mm) in hydraulics, as well as the processing of tubes with thin and thick walls. All compact bending machines with mandrel can bend up to 180°. Radii of 1.5x or 2x times the diameter of the tube are common in this application and easy to achieve with these machines, according to the company.

For the processing of tubes up to 76 mm transfluid offers its DB 2076K, capable of processing tubes with diameters of 6 mm to 76 mm and all the standard wall thicknesses and materials. To be able to obtain radii of 1.5 x D (tube diameter) of ideal quality with a bending procedure, this machine has a follower pressure die. It is operated hydraulically and supports the tubes during the bending process. This makes many applications possible, like construction of railings, tubing for installations and the production of systems for exhaust gasses.

transfluid’s K series is completed by the DB20101 bending machine with mandrel, an all-rounder that is particularly suited for the construction of pipelines, since the machine covers almost the whole range of tubes for installations. The different types of equipment available are the same as those for other types of machines. All materials can be processed and small radii can be manufactured without any problems.

All machines can be equipped with a programmable controlled mandrel withdrawal, mandrel lubrication device and wiper dies. These machines feature stable construction for reliable tube processing.
