Description
Technical field
The present invention relates to plate shearing machine field, specifically a kind of high-speed shearing device.
Background technology
Plate shearing machine is the important foundation process equipment in panel beating manufacturing industry.Tradition plate shearing machine typically uses hydraulic drive, oil pump feed, fixs row shear rate according to the cylinder diameter size of oil pump delivery with oil cylinder, often occurs because of the increasing of oil pump row, Oil pump electrical machinery also enlarged relative, noise, cost, power consumption, oil temperature, fault etc. improve simultaneously.
Summary of the invention
It is an object of the invention to provide a kind of high-speed shearing device, only need to select the driven by motor operation of oil pump of end energy consumption, to improve work efficiency, reduce noise, cost, power consumption, oil temperature and fault.
Technical scheme is as follows:
A kind of high-speed shearing device, include fuel tank, plate shearing machine hydraulic cylinder, accumulator and binder cylinder, it is characterized in that: after described fuel tank is drawn oil pipe and connected oil pump, be divided into three branch roads, after wherein the first branch road is sequentially connected with air relief valve and solenoid directional control valve YV4, on the one hand the accumulator described in accessing, accesses described plate shearing machine hydraulic cylinder after on the other hand connecting check valve；After second branch road connects one way sequence valve, the on the one hand plate shearing machine hydraulic cylinder described in access, return to described fuel tank after on the other hand connecting electromagnetic relief valve YV3；3rd branch road accesses described binder cylinder after on the one hand connecting solenoid directional control valve YV2, return to described fuel tank after on the other hand connecting electromagnetic relief valve YV1；First, second and third described branch road is connected to pressure switch altogether, and described pressure switch is electrically connected with described electromagnetic relief valve YV1, YV3 and solenoid directional control valve YV2, YV4 respectively by electric control system.
Described high-speed shearing device, it is characterised in that: described oil pipe connects in the one end of the described fuel tank internal that submerges oil filter.
Described high-speed shearing device, it is characterised in that: the side of described fuel tank connects liquidometer.
Beneficial effects of the present invention:
The present invention only need to select the driven by motor operation of oil pump of end energy consumption, when plate shearing machine is not to down cut in accumulator fuel feeding topping up, when shearing when to work, by oil pump with in the fuel feeding simultaneously of the fluid in accumulator to plate shearing machine hydraulic jack, now plate shearing machine can be sheared, when shearing completes by high-speed downstream, the oil that oil pump is discharged is supplemented with in accumulator, so that high speed shear next time, thus substantially increase the efficiency of work, reduce noise, cost, power consumption, oil temperature and fault.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
See Fig. 1, a kind of high-speed shearing device, include fuel tank 1, plate shearing machine hydraulic cylinder 2, accumulator 3 and binder cylinder 4, three branch roads it are divided into after fuel tank 1 is drawn oil pipe and connected oil pump 5, after wherein the first branch road is sequentially connected with air relief valve 6 and solenoid directional control valve YV4, on the one hand access accumulator 3, after on the other hand connecting check valve 7, access plate shearing machine hydraulic cylinder 2；After second branch road connects one way sequence valve 8, on the one hand access plate shearing machine hydraulic cylinder 2, after on the other hand connecting electromagnetic relief valve YV3, return to fuel tank 1；3rd branch road accesses binder cylinder 4 after on the one hand connecting solenoid directional control valve YV2, returns to fuel tank 1 after on the other hand connecting electromagnetic relief valve YV1；First, second and third branch road is connected to pressure switch 9 altogether, and pressure switch 9 is electrically connected with electromagnetic relief valve YV1, YV3 and solenoid directional control valve YV2, YV4 respectively by electric control system.
In the present invention, oil pipe connects in one end within fuel tank 1 of submerging oil filter 10；The side of fuel tank 1 connects liquidometer 11.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
After the electric motor starting of oil pump 5, press operation key, electromagnetic relief valve YV1 obtains electric with solenoid directional control valve YV2, the fluid that oil pump 5 is discharged flows into accumulator 3 through air relief valve 6 with solenoid directional control valve YV4 and starts topping up, after the fluid of accumulator 3 cavity of resorption reaches setting value, close oil oil pipe after air relief valve 6 pressurized and stop topping up, after system pressure is just increased to definite value set by pressure switch 9, given signal to electric control system by pressure switch 8, make electromagnetic relief valve YV1 and solenoid directional control valve YV2 dead electricity, the fluid that oil pump 5 is discharged flows back to fuel tank 1 through electromagnetic relief valve YV1, topping up completes.
After plate is ready to complete, electric control system is controlled by foot switch, make electromagnetic relief valve YV1, electromagnetic relief valve YV3 and solenoid directional control valve YV4 obtains electric, the fluid that oil pump 5 is discharged first enters binder cylinder 4 through solenoid directional control valve YV2, plate shearing machine hydraulic cylinder 2 epicoele is flowed into again through one way sequence valve 8, the fluid of accumulator 3 cavity of resorption is through solenoid directional control valve YV4 simultaneously, check valve 7 flows into plate shearing machine hydraulic cylinder 2 epicoele, make plate shearing machine hydraulic cylinder 2 band movable knife rack overcome the reverberation matrix method of kicker cylinder to start high-speed downstream to shear, after shearing completes, electromagnetic relief valve YV1, electromagnetic relief valve YV3 and solenoid directional control valve YV4 dead electricity, knife rest stops descending shearing.
After shearing completes, by limit switch to signal to electric control system, making electromagnetic relief valve YV1 obtain electric with solenoid directional control valve YV2, binder cylinder 4 is due to the effect of the runback virial of spring so that the fluid of binder cylinder 4 flows back to fuel tank 1 through electromagnetic relief valve YV1；Owing to knife rest is by the acting on of return power of kicker cylinder, knife rest starts to return, and the fluid of plate shearing machine hydraulic cylinder 2 epicoele flows back to fuel tank 1 through electromagnetic relief valve YV3；While tool rest return stroke, owing to the pressure that sets of one way sequence valve 8 is higher than the pressure of air relief valve 6, the fluid that oil pump 5 is discharged flows into accumulator 18 through air relief valve 6 with solenoid directional control valve YV4, until after supercharging pressure reaches setting value, stopping topping up.
