The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of good energy-conserving effect, the little energy-saving servopump semiconductor packages press of idle overflow loss.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of energy-saving servopump semiconductor packages press, comprise PLC controller, servo controller, servomotor and fuel tank, the output of described PLC controller is connected with the input of servo controller, described servo controller is connected with servomotor, the output of described servomotor is connected with the oil pump that the oil in the fuel tank is pumped to performance element, and the fuel injection pressure signal collector that fuel injection pressure signal is transferred to servo controller is installed in the oil circuit between described oil pump and the performance element.
The oil-in of described oil pump is connected with fuel tank by in-line, and the oil-out of oil pump is connected with hydraulic circuit by fuel-displaced pipeline, and described hydraulic circuit is connected with performance element.
Described fuel injection pressure signal collector is installed on the fuel-displaced pipeline of described oil pump.
Described fuel injection pressure signal collector adopts pressure sensor.
Described performance element is the oil cylinder of a plurality of driving device moving-members.
Described servo controller output signal is controlled the rotation of servomotor to servomotor, and described servomotor feeds back to servo controller with the tach signal transmission.
The utility model adopts said structure, have the following advantages: 1, control oil pump by servomotor in good time, can accurately control pump speed and position according to the required actual flow of performance element, pressure signal, thereby control oil pump outlet pressure, really realized the accurate output of hydraulic flow, pressure, compared with common encapsulation press at hydraulic pressure and carry out energy-conservation reaching more than 80% on the link; 2, make the complete machine hydraulic circuit simplify, save the back a plurality of branches of level oil circuit, significantly reduced the fluid pressure line of original system, make system maintenance convenient, reduced the hydraulic circuit probability of malfunction; 3, can realize almost nil idle overflow consumption, greatly reduce because the oily temperature rise that the pressure oil overflow causes, make that oily temperature temperature rise is very little, just can with oily temperature control below normal working temperature, avoid installing and using and consuming of cooling water by natural heat dissipation.Also tankage can be reduced simultaneously, reduce the use amount of hydraulic oil.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a logical construction block diagram of the present utility model;
In Fig. 1,1, the PLC controller; 2, servo controller; 3, servomotor; 4, fuel tank; 5, performance element; 6, oil pump; 7, fuel injection pressure signal collector.
Embodiment
A kind of as shown in Figure 1 energy-saving servopump semiconductor packages press, comprise PLC controller 1, servo controller 2, servomotor 3 and fuel tank 4, the output of PLC controller 1 is connected with the input of servo controller 2, servo controller 2 is connected with servomotor 3, servo controller 2 output signals are to servomotor 3, the rotation of control servomotor 3, servomotor 3 feeds back to servo controller 2 with the tach signal transmission.The output of servomotor 3 is connected with the oil pump 6 that the oil in the fuel tank 4 is pumped to performance element 5, the fuel injection pressure signal collector 7 that fuel injection pressure signal is transferred to servo controller 2 is installed in the oil circuit between oil pump 6 and the performance element 5, hydraulic valve piece also is installed, with control oil channel and drive performance element 5 in this oil circuit.Performance element 5 is the oil cylinder of a plurality of driving device moving-members.The oil-in of oil pump 6 is connected with fuel tank 4 by in-line, and the oil-out of oil pump 6 is connected with hydraulic circuit by fuel-displaced pipeline, and hydraulic circuit is connected with performance element 5.Fuel injection pressure signal collector 7 is installed on the fuel-displaced pipeline of oil pump 6.Fuel injection pressure signal collector 7 adopts pressure sensors.By the PLC controller being carried out the control that software programming realizes whole system, servo controller 2 is gathered by the fuel injection pressure signal in the fuel-displaced pipeline of pressure sensor transmission, judge whether to reach set point, then control the rotating speed of servomotor 3, thereby the power of control oil pump 6 is to realize the control to oil cylinder.
The control of this servopump semiconductor packages press has two kinds of operating states: flow control state and pressure state of a control.Under the flow control state, when pressure that pressure sensor monitored during less than the pressure set, the motor rotary speed of servo controller 2 control servomotors 3 makes the output flow of oil pump 6 remain on set point.During the flow control state, oil pump 6 is in flow closed-loop control state; Under the pressure state of a control, the pressure that pressure sensor monitored will reach or when reaching set point, the motor pressing force state of a control work of servomotor 3, the motor rotary speed of promptly controlling servomotor 3 is to minimum, only leak or the required flow of pressurize to system's control, this moment, oil pump 6 was in the pressure closed loop state of a control.
