Technical solution of the present invention is further elaborated below with reference to examples and drawings.
Embodiment 1
Present embodiments provide a kind of high beat hydraulic press comprising fuselage 1, fuel tank 2, fast drop oil cylinder 3,4 and of master cylinder
Sliding block 5.
The fuel tank 2 is set to 1 upper end of fuselage, for providing hydraulic oil, and on the upper beam of the fuselage 1
It is provided with fast drop oil cylinder 3 and master cylinder 4;In the present embodiment, the fast drop oil cylinder 3 is plunger case, and the master cylinder 4 is piston
Cylinder;And the quantity of the master cylinder 4 is two, is respectively arranged at the left and right sides of the upper beam of the fuselage 1.
The fast center position for dropping oil cylinder 3 and being set to the upper beam of the fuselage 1, and the fast drop oil cylinder 3
Cylinder body is fixed on the upper beam of the fuselage 1, and the plunger rod of the fast drop oil cylinder 3 is fixed on the sliding block 5.
Similarly, the cylinder body of the master cylinder 4 also is secured to the upper beam of the fuselage 1, the piston rod of the master cylinder 4
It is fixed on the sliding block 5, to work as the fast drop oil cylinder 3 by the upper chamber of injection hydraulic oil or master cylinder 4 by injection hydraulic oil
When, the fast drop oil cylinder 3 and master cylinder 4 are jointly with 5 fast downlink of movable slider.
For example, the impulse stroke of sliding block 5 is subdivided into the following three stage:
The A stage: press pressurization in fast drop oil cylinder 3, sliding block reaches 11% nominal pressure (master cylinder is not involved in work).
B-stage: master cylinder 4 and the middle pressure pressurization of fast drop oil cylinder 3.Sliding block reaches 55% nominal pressure.
C-stage: master cylinder 4 and fast drop oil cylinder 3 are pressurized pressurization.Sliding block reaches 100% nominal pressure (26MPa).
It is highly preferred that the cylinder bottom of the fast drop oil cylinder 3 is integrated with control flow path, in the present embodiment, the fast drop oil cylinder 3
Cylinder bottom offers cavity volume 10, and the periphery of the cavity volume 10 is formed with what multiple (such as 4) be connected to the cavity volume 10
Control piper, and the cavity volume 10 is also connected to the internal chamber of the fast drop oil cylinder 3, to connect in the cavity volume 10
When being connected to oil feed line, hydraulic oil can be provided to fast drop oil cylinder 3 and master cylinder 4 from the cavity volume 10, at this point, the control
Tubulation road is connected to the upper chamber of master cylinder 4, to realize that the cylinder bottom of control valve and plunger case is directly connected to, shortens pipe
Road length, is conducive to damping;And simplify and optimize connecting line;It is highly preferred that installing plug-in side on the cavity volume
To valve, to pass through the on-off of the plug-in direction valve control piper.
The lower chambers of the master cylinder 4 are connected to accumulator 7, and in the present embodiment, the accumulator 7 is plunger type accumulation of energy
Device, in 5 downlink of sliding block, accumulator due to releasing energy outward at this time, pressure decline, under the pressure for reaching accumulator
Limit, can be discharged accumulator 7 for the hydraulic oil in the master cylinder 4, so that dropping oil cylinder 3 fastly by plunger type will be under master cylinder 4
It is stored in chamber oil extraction push-in piston accumulator 7, oil extraction loss has not only been avoided, but also 7 repairing energy storage of accumulator can be made, for sliding block
It is used when 5 backhaul.
The accumulator 7 presses energy storage (14~18MPa) in using, to be able to satisfy 5 return pressure of sliding block and proportioning valve guide
Subject to control-oil pressure.And the nominal pressure of press is realized by pressurizing cylinder 9.Lower energy storage pressure not only makes electricity
Machine peak power reduces, and energy storage loss caused by also making because of leakage tends to reduce, and can be reached by the pressurizing cylinder 9
It 1.8 times of energy storage pressure and exports outward, the pressurizing cylinder 9 is connected to the fast drop oil cylinder 3 by proportional throttle valve at this time
With master cylinder 4, moved downward so that when the proportional throttle valve is opened, master cylinder 4 can be driven and drop oil cylinder 3 fastly.
Especially, the high beat hydraulic press further includes the variable-frequency motor 8 of oil pump and the driving oil pump, the oil pump
It is connected to the accumulator 7, so that oil pump does not provide energy, the program-controlled release of the energy put aside in piston accumulator directly
Fuel feeding, installed power also make network load more than reducing 20%~50% or more using the high speed hydraulic press of oil pump direct-furnish energy
It tends to be steady.
The nitrogen cylinder 6 is connected to piston accumulator 7, to provide the gas of high pressure to piston accumulator 7, keeps living
The pressure for the hydraulic oil that plug accumulator 7 is provided out.
In the present embodiment, the control system schematic diagram of the high beat hydraulic press is as shown in Figure 3, wherein Unloading Control block is used
In the unloading of the fast drop oil cylinder 3 and master cylinder 4 of control, with when drop oil cylinder 3 and master cylinder 4 move upwards fastly, the liquid of upper chamber
Pressure oil is unloaded into fuel tank;Further, the Unloading Control block carries out pilot control by the hydraulic oil in accumulator.
In the present embodiment, the link block, master slider control block, accumulator control block and Unloading Control block are by controlling
Valve group is at being achieved in the control of fast drop oil cylinder 3 and master cylinder 4.
The setting by dropping oil cylinder 3 and master cylinder 4 fastly of the invention, can be improved sliding block 5 in the speed of uplink and downlink,
And the duration in 5 motion process of sliding block is reduced, so that high beat hydraulic press work pace per minute is saved up to 1~25 time
It is stepless adjustable to clap number, and impulse stroke is longer, stroke adjustable extent is larger, relative to the lower quick liquid of tradition of work pace
Press and nominal pressure stroke are limited mechanical press less than normal, have preferable technical effect, and be suitable for intelligent type automatic
Production line, than high speed hydraulic press using electricity wisely 20%~50%.
In the present embodiment, the high beat hydraulic press further includes redundancy (spare) motor and pump group, and the pump group
It is connected to the accumulator, so that the redundancy motor and pump group can be passed through in variable-frequency motor and in damaged condition oil pump
Energy is provided to accumulator.
