Versatile metal tubes end-forming from BLM Group

The E-Form by BLM Group is a powerful and versatile end-forming system for metal tube ends able to carry out many integrated operations, such as deformation, end-machining, forming and rolling. It is possible to program over 9 passes, that can be 7 push passes and 2 revolving or 6 push passes and 3 revolving. The space on machine top enables forming complex parts therefore widening the machine field of application.

Programming is simplified thanks to the implementation of VGP2D, and all handling axes are electrically driven and NC controlled, ensuring very high positioning accuracy and set-up times reduced to a minimum. A vice clamping system with a force of 25 t and a greater clamping strength, combined with the choice of single punch feed with a thrust force up to 10 t, ensure a better quality of end-forming. The process is also more reliable and effective for machining thicker materials and stainless steel. It is also possible to have punches with different lengths without any interference with the vice.

Tool stroke increase widens the machining possibilities on E-Form making it possible to carry out forming at a greater distance from tube end. Finally, the all-electric differential rolling system with three controlled axes,can work on copper, aluminium and stainless steel tubes up to 30 mm long. Adjustment and handling of rollers is carried out by two electrical axes whereas another axis controls the contrast mandrel axial to the tube.
