Quick and economic tube forming, also in combination
transfluid combines the advantages of axial and roll forming with its “t form” combination machines
To distinguish yourself from the competition you will need to be in good form. This is true not only in sport, but especially also for tube forming. This is because time-consuming and expensive soldering and welding is often still deployed, especially for tube connections. Users need to deploy more efficient methods to also strengthen their market position in this field of manufacture. The South Westphalian company transfluid Maschinenbau GmbH is determined to find a solution to this challenge: Managing Director Stefanie Flaeper explains the technical options: “Forming geometries are the answer to most of the requirements here, offering distinct economic advantages. They may be produced with absolute reliability of processing and functionality. Especially forming geometries with O rings are of particular significance in many products, as found in the automobile industry, for instance. Geometries which include a flange for fitment at a later stage are also often needed.”
From soldering to reliable forming
Forms of this type are ideally created using machines capable of both swaging and rolling. The specially developed transfluid combination systems automatically feed such external components during swaging as needed, accurately positioning and fastening them. This process also creates a “pre-form” which may be required for any downstream rolling.
Rolling produces the final geometry, creating perfect surfaces for optimal application. “The tolerances, incidentally, are quite comparable with tolerances produced during machining”, explains Stefanie Flaeper. Since extreme precision is required especially during rolling, the rolling head is CNC controlled and freely programmable in all axes of movement, even including overlap. Combination machines allow reliable and effective processing, even for large diameter tubes. For smaller tube sizes, transfluid units are particularly energy-efficient and are driven extremely accurately by servomotors. All types of material may of course be processed reliably.
