The Transfluid T-Form UMR shape tubes either in a rolling or rotational process. For instance, the bead rolling machine uses a rolling process that makes it possible to achieve various forming results on the extremity of the tube, including threads. The rotational process is, on the other hand, able to carry out multiple flaring operations at the end of the tube, at an angle to the diameter between 20° and 90°, or contoured (for instance ball-shaped).
In the past it was necessary to set stops and strokes manually for both machines, in order to achieve optimised surface geometries. However, the latest generation machines – T-Form UMR 628, 642 and 2090 – only require a very simple tool substitution by the operator, which takes less than five minutes. Now, the equipment includes a complete selection of flaring geometries to choose from electronically. The position of the stop, as well as all the strokes and operations, are controlled servo-electrically and can be retrieved via a touch panel.
The material and type of forming required are crucial for the exact timing of the process. Here, T-Form UMR machines complete the process almost independently, making it possible to retrieve the size of tube, together with the required process parameters. In each case the clamping length for the production processes are between 1xD and 1.5xD of the tube. In this way, the operator always has the option to carry out the forming after the bending steps.
With this solution, Transfluid says it is possible to achieve the economic production of complex forming geometries and flaring, with polished sealing surfaces, in a single forming step.
