MACHINES WITH A ROTARY BENDING BOLSTER
The machine with a rotary bending bolster (IV 2144 model) is designed for the manufacture of various parts from sheet metal by bending.<br>
MACHINES WITH A ROTARY BENDING BOLSTER
With the tool supplied with the machine, it is possible to bend a large number of different parts with an internal angle from 32 ° to 180 ° and a radius of 7 mm.
The machine can be equipped for a fee with various interchangeable devices: for bending pipes, closed circuits, U-shapes, boxes and edges.
The operation of the press is provided by a hydraulic system containing two main drive cylinders, two pressure bolster cylinders and a hydraulic station. The hydraulic drive provides fast approach of the bending bolster to the workpiece, slow motion during bending and fast retraction to the starting position. Position adjustment of the bending and pressure bolsters, depending on the thickness of the bent sheet and the required bending angle, is carried out by manual adjustment mechanisms.
The backgauge with the bending line position indicator designed for accurate positioning of the sheet is installed on the machine.
The electrical circuit ensures the operation of the machine in single strokes and in the adjustment mode.
Lubrication - combined, the most loaded mechanisms are lubricated by a centralized grease lubrication system. The rest of the rubbing surfaces are lubricated with a syringe.
