3-roll plate bending rolls TBH Hydrotronic

 

3-Roll Double Pinch Plate Bending Rolls type TBH. Fully Hydraulic.

Rolls length up to 8.000mm, plate thickness up to 150 mm.

 

The TBH bending machines are equipped with the exclusive Parmigiani Parallelism System (PPS) for rolls parallelism control (closed ring type).

The PPS assures the max precision in rolls positioning also after several years of intensive work.

 

Rolls rectilinear slideways coated with antifriction material (AVG System).

(No maintenance; High loading and carrying capacity; Smooth and stable positioning).

 

All rolls (mounted on roller bearings) are driven by separate hydraulic motor for each roll.

CNC on request.

Main technical characteristichs of TBH Hydrotronic:

● Machine uprights with heavy-duty RECTILINEAR GUIDE for lower rolls traslation.

● Bending Rolls support with antifriction material in sliding area.

● N° 3 driving rolls by n° 3 hydraulic motors + 3 planetary speed reduction gears.

● HMB  Heavy Multi Bearings System for rolls support and rotation (4 heavy-duty bearings for roll; 2 at each side).

● Bending rolls synchronisation and balancing control fully electronically controlled by a SIEMENS industrial unit.

● Stepless variable tilting (from control panel) of the two lower rolls on both way, positive or negative.

● Lower rolls tilting from operator control panel.

● Hydraulic opening of the turn-bearing for shell unloading.

● Safety against the opening of the turn-bearing when lower rolls are under pressure.

● Large rolls diameter for minumum deflection.

● Multi-system safety device for instantaneous stopping of all movements.

● Mobile (on whells) push-button operator control panel, with low voltage controls.
