Crossbeams made of electro-welded steel, subjected to normalising heat treatment.
The supporting frames of the rolls’ movement cylinders are made of electro-welded steel, subjected to normalising heat treatment
Rolls in special carbon steel (C45 or C50) subjected to thermal hardening treatment.
– Two rolls are motorised with no. 2 epicyclic reduction gears and no. 2 hydraulic motors for their rotation.
– The side rolls and bottom roll have independent positioning movement by means of the hydraulic cylinders.
– Side rolls are electronically tilted (controlled by the PLC) for the production of conical plates.
– Movement of side and bottom rolls with a straight guide system
– The rotation system of the rolls consists of two hydraulic motors coupled with two epicyclic reduction gears, directly fitted on the rolls.
Automatic speed/pressure balance between the upper roll and bottom rolls;
Linear potentiometers fitted on each roll (two on each roll) that allow electronic control of parallelism between rolls.
Radial bearings fitted on all rolls, self-aligning as double row SKF or FAG branded bearings
Two pumps or up to six for the bigger sizes for maximum linear and rotational thrust. Having a system with more pumps always produces simultaneous movements, including the possibility of both rotating and pressing up to the maximum capacity, and in the event of pump failure, the machine can also be operated, even if the performance is reduced.
The cylinders are made of alloy steel and carbon steel with a chrome-plated rod and use seals from the primary brands.
Hydraulic control unit consisting of: motor pump unit, electro valves, pressure relief valves which guarantee overload protection.
Hydraulic opening handle to allow the produced tube removal in horizontal position.
Automatic centralised lubrication system with a pump which has an autonomous tank, programmable from the touch panel.
Siemens, ABB, Telemecanique, Moeller electrical system. It consists of a mobile console control panel connected to the machine with low voltage and a general cabinet where there are all of the other electrical components, as well as the machine control PLC SIEMENS S7.
Independent SIEMENS KTP1200 PN control Touch Panel with a 12” touch screen colour display. By changing pages it is possible to see on the display the position, the balance of the rolls, to setup and read the tilting of the rolls, to set their speed (two rotation speeds), the diagnostic functions and machine alarm.
Modem to remotely control the PLC in case of software changes and resolution of machine faults.
Heat exchanger for the hydraulic oil;
