Hydraulic press is developed for producing products in a
dry-pressed way. The integration of mechanical, electrical,
hydraulic, pneumatic and computerization into a machine, the
hydraulic press consists of main body, hydraulic system, feeding
system, electric control system, mould loading/unloading system and
so on.The filling, pressing, demould, unloading and oil spraying
are fulfilled automatically throughout the cycle. Apart from the
inherited features, stability, advanced performance and low failure
rate, the refractory press also enjoys the below advantages through
rationalization of core technology:
Wide applicability
Thanks to the optimum hardware configuration, various settings are
made possible to meet the needs for product of raw material
characteristics, shapes and sizes.
Accurate product size control
The displacement of pressing cylinder and mobile mould frame is
monitored by high-performance linear position sensor. The product
size is controlled in a close-loop way that the adjustment is
performed automatically to ensure the tolerance.
Dual pressing
The floating mould frame and main cylinder are controlled
accurately in such a way that movement is synchronized, realizing
the dual pressing for optimum density distribution.
Precise close-loop pressure control
With the help of the feedback from pressure transducer and data
processed by PLC, the pressure is controlled in a close-loop manner
for varied speed pressurization and multiple deaeration to minimize
porosity and increase density.
Volumetric filling device
Volumetric filling device equipped with material crusher and mixer,
controlled by proportional technology, makes sure that the material
in distributed evenly in the mould cavity and effectively avoids
clustering and liquation in order the control weight variation
within the limit.
Fast mould change-over
Fast mould change device is controlled by hydraulics to make it
possible to change the mould and lock it automatically to meet the
demand of producing product with frequent mould change-over.
Highly automated
Filling, forming, extracting and gripping, etc, in the manners of
mechanic, electric, hydraulic and pneumatic, are all controlled by
automation to reduce human error and labor cost.
Digitalized smart control system
User-friendly interface and remote diagnosis technology. The switch
of working mode, pressure control, thickness adjustment,
plunger/speed control, etc are performed on the HMI. The error
message and PLC input/output dynamic simulation are also shown on
the HMI. With a DVP module, the DVP card value can be accessed and
modify easily. The remote communication device can set up a remote
control system for trouble-shooting and upgrade of program
conveniently.
Safe and energy-saving
An overall safety system to prevent the damage to staff and machine
caused by human error which is seen in friction press. The noise
level is controlled effectively during the pressing stage and
transport system for material is properly sealed to avoid dusting,
so as to improve working environment for workers and reduce harm to
health. Variable displacement pump with constant power control are used as
main pump and auxiliary pump, respectively, to reduces heat
dissipation and save energy.
Low maintenance cost
Full-flow filtering and heat exchanging system greatly reduce the
system malfunction caused by contamination of oil. Oil temperature
is maintained at an optimum level. The hydraulic units and
electronics are from world-famous suppliers.
