Remark: The above data are recommended, and can be discussed with end user
| Manual (inching) | Pushing each button is for each related action The mode is mainly for press adjustment and mounting toolings |
| Automatic | Each pushing is for a working circle |
Two modes are shifted through switch, and press is controlled by both buttons and touch-screen.
| Mechanical system | Steel wire winding type frame is finite element analyzed by computer for sufficient rigidity and stiffness.
Four guide rails are for the guiding of slider, strong resistance to unbalance loading
The lower surface of slider is with T-slots
Single oil cylinder is working cylinder. The cylinder is made from alloy steel |
| Hydraulic system | Drive: Motors, pumps Control: Control valves, pressure valves, directional valves. filling device, Auxiliary: Oil tank, cooling device, lubrication device, pipeline Accessories: Flanges, connectors, gauges, filters
Constant power high pressure plunger pump is equipped
Oil liquid level, oil temperature is real-time monitored and displayed, alarm is automatically sent in case of any failure.
Hydraulic pipes are anti-rust treated, and connected with flanges
|
| Electrical System | The press is operated through an operational panel and a suspend operational table, they are inter-locked. PLC + touch-screen display Slider stroke, ejector stroke, working force can be set and displayed through touch-screen
General power switch and motor switches, protective switch is for the safety of system
Electrical cabinets are equipped with ventilation device and lighting device
The four angles of the press frame are installed with emergency stop buttons
Slider displacement is measured by displacement transducer, and measuring accuracy is ± 0.05mm
Travel switches for both upper limit position and lower limit position ensure safety in case of incorrect operation |
| Cooling System | Automatic cooling system When oil temperature is over 45℃, cooling works When oil temperature is over 60℃, press work stops, only cooling works Individual plate type heat exchanger |
| Lubrication System | Individual forced circulating lubrication for the slider It inter-locks with the slider, the press does not work if no startup of lubrication system Alarm is automatically sent in case of shortage of lube Lube volume and lubrication period is pre-set |
| Safety & Protection | Slider keep stationary at any stroke position in case of power failure. It is called support system Over-loading protection for hydraulic system |
