3.The main components of hydraulic cold press
Themain components: oil hydraulic system, electricalcontrol system, press plate and machine body.
Oil hydraulic system: it consists of oil cylinder, fuel tank, oil pump, oil pump motor, control valves and pressure gauge.The fuel tank is filled with oil, it achieves oil pumping by electric drive pump, and transports the oil to oil cylinder by pipeline, so that the oil cylinder can work. The overflow valve can make the workpiece generate backpressure in pressing process and maintain steady. The electromagnetic valve ball is used to maintain the system setting pressure; the pressure gauge is used to show the pressure.
Electrical control system: it consists of main circuit and control circuit, the circuit uses automatic circuit breaker, fuse,AC contactor to carry out overload, short circuit and under voltage protection for press motor, solenoid valve, etc.
Press plate balance mechanism: it consists of balance lifting rack, lifting gear, rotation axis. The machine is equipped with fixed rotating bearing components, two balance racks (right and left). The both ends of rotating shafts are equipped with lifting gears and bearings, so that the rotation axis can rotate flexibly.
Press plate: it consists of the upper press plate and the lower press plate. Both press plates are welded by section barsand steel plates, the working plane is processed by large gantry milling machine to ensure it smooth. The upper press plate is connected with the cylinder rod, realizing press plate lifting by lifting cylinder. The lower press plate can be welded directly on the machine base, making the structure of machine fastened.
Machine body: it is welded by steel plate, the structure is compact and strength is good.
4.Storage
Toprolongthelife ofthe press, please do not: put in damp places, vibrate severely.
Machine transportation and load & unload
It is generally the overall transport, but if it needs to disassemble the oil cylinder to transport because of the height, you can remove the bolts on the flange, and pull the cylinder barrel down, then fix two oil cylinders with a batten or iron bar, which protects two oil cylinders from waggling during transportation to result in any damages. At last, pack the press well. It is forbidden to place inclining to one side when loading.

6.Installation and operation
The placement ofmachine
(1) Place the machine on the flat and hard ground, and adjust the machine to horizontal position.
(2)Power distribution
Connect voltage, electric current and frequency-dependent power tothe head of the machine power outlet according tothe power distribution requirements on electric box.
(3)Confirm theoilcylinder motor turninginthe right direction. Press the power start button, and press the press plate pressing button, if the press plate is pressing down (if the cylinderis lowered, then the cylinder rises), then the turning direction of oil cylinder motor is correct. Otherwise, you should change over two lines of the three-phase power supply cord to get correct turning direction.
Oil cylinder reset
If the oil cylinder stops declining before transportation, then reset the oil cylinder and fixit after power distribution:A: Remove the batten and package fixing between two oil cylinders.
B: Turn the power on.
C: Press the dropping button, the oil cylinder will rise automatically; if the oil cylinder doesn’t work because of wrong power phase and motor reversal, when the oil cylinder flange rises to about 3mm from the roof, press the stop button to stop the oil cylinder rising, then tighten each flange and bolt.
(4)Pressure retaining time setting
You can set the pressure retaining time according to actual demand.A: Choose the time mode: “hour (h), minute (M), second (S)”.
B:Settherequired number byfour digits"0-9":
If you choose the time mode is "h", the set value is: “9999”, the actual pressure retaining time is "99.99" hours; if the value is “0003”, the actual pressure retaining time is "0.03" hours; if the value is “0905”, the actual pressure retainingtime is "9.05" hours (If the time mode is set to " M" or " S", then the "hour" is changed to "minute" or "second").
C: The maximumtime value can be set to "99.99 hours".
D: After time up, the buzzer will ring, it is suggested that the workpiece hasbeen completed pressurizing.E: Prohibit setting the time to "0000".
(5)The placement of workpiece
Before pressing the workpiece, it must be based on the actual size and height of the workpiece to select the correct placement, strictly prohibit pressurizing the workpiece inclining to one side or uneven. Before operating this machine, you should carry out a comprehensive and detailed examination to ensure safe operation:
(1) Check all safety guards are correct and reliable.
(2) Check the transmission components and connecting components.
(3) Check the pressure of hydraulic system.
(4) Checkifthe oil pump rotation direction is correct.
(5) Check ifthe lifting actionis flexible andreliable.
(6) Finally, operate theempty machine once, confirm whether the entire operation process is correct. Put the workpiece with correct method-------- →set the pressure according to the area of workpiece →set pressure retaining time by adjusting the time relay “B” →press the pressing button “E” →after compressing the workpiece and reaching the set pressure, the pressure retaining relay starts counting, the press plate will rise automatically when counting is completed - →remove the compressed workpiece, if you do not needthe pressure retaining time, then adjust time relay "H" to "9999" before pressing.
