the working status.

1.4

The seals can be replaced without major cylinder being moved away from its installed

position.

1.5 4

Sliding blocks are respectively supported by 4 fast cylinders to go fleetly, greatly reducing

ineffective time consumption.

1.6 ,The hydraulic system adopts intensifier which can use lower system pressure, enhancing the

reliability of hydraulic system.

1.7

The adjustable high pressure pump and large flow low pressure pump will work together in

oil supplying, which can realize the pressing speed infinite variable control to save energy in

fast going up procedures.

1.8

3.2 Hydraulic system

The hydraulic system of the equipment is consisted of the major system, ultra high

pressure control system and the supplementary control system.

1.

The manual variable volume piston pump and low pressure hydraulic gear pump are used for

oil supplying.

2.

Reciprocating-type intensifiers are used in the ultra high pressure system to realize pressure

increase and release with the help of the ultra high pressure valve assembly..

:

Working principles of the hydraulic system:

Empty fast going up: The low pressure gear pump supply oil for 4 sets of fast cylinder,

which will bring the slide go up quickly. At the same time, the hydraulic oil in oil tank will go

through ultra-high pressure prefill valve to fill into main cylinder.

,

Pressurization: When the fast rising material contact with upper working table, the limit

switch will send signal (or by pressure sending signal) to change working status to

pressurization. The gear pump will unload, and the variable plunger pump will begin to work

by providing pressure directly to main cylinder with the help of controlling valve blocks. The

pressure will be set and originated by pressure sensor. If the procedure is too fast, it can be

changed to supply oil by booster.

Pressure increase: When the pressure of the pump is up to set value, the pump will provide

oil through reversing valve until the repeat working of intensifier, which will make the

pressure to final value by the way of outputting ultra-high pressure oil to main cylinder

Pressure keeping: Pressure keeping starts when the pressure reaches stipulated value and

the pump enters load release status. When the pressure is released to set value at which the

pressure will continue to raise, the pressure will keep a stable value in this way. The pressure keeping brings to an end the opening operation of the pressure release valve of both

sides to facilitate steady and fast pressure release of the liquid in the cylinder.


7/14

-70MN

Return travel: With the opening of liquid filing valve and fast cylinder oil releasing valve

at the bottom of the cylinder, the slide will realize quick stroke under the double action of

gravity and return cylinders.

Electric control and protection system

Q PLC

The electric system adopts Japanese Mitsubishi Q series PLC to realize control of every

working position of the press.

a. Operation system:

Two-hand operation is maintained by two hands, safe and

reliable. b. Safety protection system:

The press is accompanied with safety relay, making the equipment reliable andsafe.

0.1 Mpa

For safety and reliability, the connection contact pressure meter, signal giving for

ultra pressure alert and immediate pressure release are installed with the press in addition to

pressure sensor. The precision is 0.1M pa.

Emergency buttons accompanied with recovery functions are available with two sides of

press, facilitating easy maintenance, repairing and operation.

c.

System for self inspection of operation status:

The touch screen shows its position and the working status of the electromagnetic valve of the


10/14

-70MN

hydraulic system. The working pressure is shown on the touch screen as well as on the digital

status indicator.

The alarming device in the electric control system shows category of the alarm, giving an

order the repairman for repairing and indicating the statistics of the number of

maintenance and repairing.

Temperature sensor is mounted in the oil tank gauge to check temperature of oil and start

the plate heat exchanger automatically according to setting temperature. When the

temperature excesses the setting value, press will shut down immediately.

Oil flitting device are mounted in the oil inlet of pump, which have the check device for

oil cleansing. When there is impurity, indicator will alarm and press shut down.

Two hand operation button control box is installed beside the press which can be easily

manipulated.
