Time-efficiency and quality of the end results play a crucial role in efficient forming processes of tube endings. To achieve this, the high-tech machine manufacturer transfluid has completely re-engineered its ‘t form UMR’ forming machine. The proven benefits of the unit were kept and more added, to reduce the process time and achieve better surface results, irrespective of whether you are working with seamless tubes or tubes with longitudinal welding seams.

Electronic pre-selection saves time and manpower

The transfluid solutions 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, with high-precision reduction over a long distance, and amongst other things it can create a thread with the rolling system.

The rotational process is on the other hand able to carry out multiple flaring 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 good geometries on the surface. The latest generation of machines ‚t form UMR‘ 628, 642 and 2090 only require a very simple tool substitution by the operator, which doesn’t even take five minutes“, says Stefanie Flaeper about the benefits of the latest tube forming machines. 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 that is processed and the type of forming that is required are crucial for the exact timing of the process. The machines completes the process almost independently, when it is possible to retrieve the size of the tube together with the required process parameters. In each case the clamping length for the production process are between 1x and 1.5x the diameter of the tube. This way the operator always has the option to carry out the forming after the bending steps. With this solution transfluid makes it possible to have a more economical production of complex forming geometries and flaring with polished sealing surfaces in one single forming step.
