CAN-BUS

A co-operation to develop the control of several hydraulic axes

“Designing a modern machine for the metal deformation using the best features of
the modern hydraulic technology”

Such words brought Duplomatic Oleodinamica to the technical co-operation with an important leading company in the sector of the metal deformation, in order to develop a new bidirectional folding press.

The bidirectional folders with double oscillating valve can process metals with thicknesses ranging from 8 to 20 mm and a width from 2 to 8 meters.

The hydraulic system has been developed to control several hydraulic axes by means of the new DSE5G and DSPE*G proportional valves equipped with the CAN-BUS communication system.

Such proportional valves allow to control and synchronize all the hydraulic axes with a single PLC for the management of the position and parallelism closed loop to which the digital position sensors are connected.

The repeatability and linearity of these new proportional valves with digital integrated electronics allow to obtain decimal precision values (+/- 0.1mm) and a very high level of valve interchangeability, thus reducing the machine start-up times.

The control of the hydraulic pressure is obtained through a PRE*G valve with integrated electronics; such valve is equipped with the CAN-BUS communication system for the parameterization of the product.
