Details of "HPR Series"
PRESS STRUCTURE AND PRESSING GROUP
HPR 600 is a six hundred Tons press ( 600 Tons – 5.88 MN).
press consists of two high thickness steel standards on which
pressing force discharge itself from the crossbeam and cylinder.
The movable crossbeam, which supports pressing punches, moves forward on
special high precision prismatic slide guides.
The moulds, based on a unique concept, are made of special steel and
allow the production of tableware of different shapes (square, round,
hexagonal, octagonal as well as other forms) and size.
The steel dies are rubber coated on their working surface to prevent
sticking. It is also possible to use special isostatic punches.
After pressing, the moulds open and the items and pieces pressed detach
from the punches and are received by a special take-off conveyor.
The pieces, produced with our moulds, have rounded edges allowing the
multi-station fettling machine to make only a simple finishing. Thus
reducing production loss during fettling to a minimum.
HYDRAULIC UNIT AND COMPUTER CONTROL
All movable parts are driver by a hydraulic circuit and controlled by
an electronic panel.
Electro-valves and hydraulic logic elements being the best brand names.
As a matter of fact we use proportional control valves with
feedback commands that can improve the coordination of positioning and
timing of the die filling, pressing and ejection.
All the electronic devices are controlled by means of a computer:
- Control of speed and positioning by a modulated signal system that
directly pilots valves with feedback commands
- Control of pressing force by means of pressure sensor and a
- Electronic control of cycle
- Automatic thickness control and regulation
- Memorization on floppy disk of the most interesting and relevant
information (i.e.: “regulation recipes”, ordinary maintenance,
production statistic data, alarms).
Oil filtering is ensured by a pump/filter group. Oil
cooling achieved via heat exchanger (by water) complete with
