Description
Technical field
The present invention relates to hydraulic means field, is moved in particular to a kind of energy-saving hydraulic system for batch (-type) acting
Power source and the energy-conserving hydraulic work system for using the batch (-type) of the power source to do work.
Background technology
In press device field, there are many power to be realized using hydraulic way, such as punch press, plate shearing machine, forming press.
During hydraulic drive, hydraulic system utilizes hydraulic pump by prime mover（Motor, oil-burning machine）Mechanical energy be converted to the pressure energy of liquid,
Energy is transmitted by the change of liquid pressure energy, by the transmission of various control valves and pipeline, by means of hydraulic actuator
Liquid pressure energy is converted to mechanical energy by (hydraulic cylinder or motor), so as to drive operating mechanism, is realized straight reciprocating motion and is returned
Transhipment is dynamic.At present, when needing high-power output, typically powerful motor is equipped with to hydraulic pump, but for batch (-type)
Situation about externally doing work, such as punch press, only just need high-power output in the moment of punching press, and other times only need to remain past
The small-power output moved again, will in the small-power output period if being also equipped with heavy-duty motor in this case
The waste of energy is produced, the energy of now motor output is lost in the form of hydraulic oil heat dissipation, but if is changed to be equipped with
Low-power machine, power demand is unable to reach again needing the moment of high-power output.According to high-voltage energy storage device, although energy
Realize that momentary high power does work, but high-voltage energy storage process is slow, can not realize zero load at a high speed, it is less efficient, simultaneously because tool
There is accumulation of energy process that there is larger heat loss, energy-saving effect is not ideal enough.Therefore, in the hydraulic system of batch (-type) acting,
So far also momentary high power acting is carried out by low-power machine and can be unloaded with energy-saving effect at a high speed without a kind of
Power source.
The content of the invention
It is an object of the invention to provide a kind of energy-saving hydraulic system power source for batch (-type) acting, the power source can will be small
Power motor and high-volume hydraulic pump, which are combined, externally carries out moment high-power acting and at a high speed zero load, can greatly save energy
Source, ensure operating efficiency, and fault rate is extremely low.
To achieve the above object, the present invention takes following technical scheme：
A kind of energy-saving hydraulic system power source for batch (-type) acting, including motor and hydraulic pump, it is characterised in that the liquid
Press pump is connected with motor through power transmission shaft, and flywheel is equipped with power transmission shaft.
Preferably, the power intake of the hydraulic pump is connected through first shaft coupling with described power transmission shaft one end, the electricity
The clutch end of machine is connected through second shaft coupling with the other end of the power transmission shaft.
The present invention also provides a kind of energy-conserving hydraulic work system of batch (-type) acting, including hydraulic actuator, control valve,
Power source and fuel tank, the fuel tank are connected through the first oil circuit with power source, and power source is connected through the second oil circuit with control valve, control
Valve processed is connected through the 3rd oil circuit with fuel tank, and the control valve is also respectively through the 4th oil circuit and the 5th oil circuit and hydraulic actuator phase
Even, the power source is using the above-mentioned energy-saving hydraulic system power source for batch (-type) acting.
The power source has multiple, and is connected in parallel in the control valve.
The hydraulic actuator is hydraulic cylinder or motor.
The piston of the hydraulic cylinder is connected with the drift of punch press.
In above-mentioned technical proposal, flywheel is mounted with the power transmission shaft of motor and hydraulic pump, motor driven hydraulic pump and fly
Wheel operates together, while the energy storage of abundance on flywheel, motor can use smaller power motor, be not required to and hydraulic cylinder
Moment externally do work it is high-power match, hydraulic pump can use high-volume hydraulic pump, in hydraulic cylinder external moment acting,
For example punch press, in punch elements, the energy of punching press moment flywheel can carry out quick release, so that hydraulic cylinder obtains big work(
Rate, complete punching press.Due to the size of flywheel can do it is larger, acting moment rotating speed will not lose a lot, after acting according to
It is unloaded at a high speed so as to realize that larger rotating speed can so be kept, so as to realize power cycle rapidly and efficiently.It can therefore be seen that this
The power source of patent and the energy-conserving hydraulic work system thus formed, have the following advantages that：1st, high energy-conservation, is avoided using high-power
Motor, save electric energy, while it is unloaded when hydraulic oil can directly flow back to fuel tank, substantially without heat loss；2nd, noise is low, compared to motor
For direct flywheel driven and bent axle mode of work-doing, friction is small, and noise is very low；3rd, this power source structure is very simple, avoids multiple
Miscellaneous transmission process, not easy break-down.
