Description
Technical field
The invention belongs to hydraulic press technical fields, and control system is padded more particularly to the energy-conserving hydraulic for hydraulic press.
Background technology
Hydraulic press is widely used during automobile stamping, and environmentally protective is the theme of 21 century industrial development, hydraulic press
Designing technique is promoted, and on the one hand to be improved production efficiency, on the other hand be required energy saving and reduce cost.
Conventional hydraulic machine hydraulic die cushion control system stretches pressing process action according to conventional, in drawing process, hydraulic die cushion with
A large amount of high pressure oils are discharged into fuel tank by overflow valve when slide block down, are then pumped by hydraulic die cushion and jack up hydraulic die cushion, waited for next
A process cycles action.There are two resulting problems, will produce greatly first, a large amount of high pressure oils are discharged into fuel tank by overflow valve
Energy, conventional hydraulic mattress system does not utilize these energy, but these energy is allowed to be fully converted into heat；Second is that punching press
Hydraulic press generally requires hydraulic die cushion to jack up speed, it is also necessary to configure a large discharge pump group for jacking up.
Invention content
The technical problem to be solved by the present invention is to：A kind of energy-conserving hydraulic pad control system for hydraulic press is provided, this is specially
Profit is discharged using the energy generated in accumulator storage drawing process and during the jack-up of hydraulic die cushion, reaches reduction system hair
Power and discharge capacity that hydraulic die cushion jacks up pump group can be reduced while hot, reduce cost.
The present invention is adopted the technical scheme that solve technical problem present in known technology：
A kind of energy-conserving hydraulic for hydraulic press pads control system, includes at least：Hydraulic cushion cylinder (1), prefill valve (2), liquid
Pressure pad control valve block (3), pressure sensor (4), accumulator (5), the safe valve group of accumulator (6), hydraulic die cushion jack up pump group (7) and
Power fuel tank (8)；Wherein：
The hydraulic die cushion control valve block (3) is located above power fuel tank (8), and hydraulic die cushion control valve block (3) is connected by oil pipe
Connect hydraulic cushion cylinder (1) and accumulator (5), hydraulic die cushion is with the passive downlink of sliding block, and fluid passes through prefill valve (2) in hydraulic cushion cylinder (1)
It is discharged into hydraulic die cushion control valve block (3), then be discharged into accumulator (5) by pipeline, fluid passes through liquid in accumulator (5) when jack-up
Pressure pad controls valve block (3) and reaches in hydraulic cushion cylinder (1), and driving hydraulic die cushion jacks up.
The invention has the advantages and positive effects that：
By using above-mentioned technical proposal, the present invention uses on the basis of conventional hydraulic pads control system, increases storage
Energy device stores tensile energy, is pushed to return to the principle of stretch position using the energy of storage when hydraulic die cushion needs to jack up, subtracted
Lack system heat generation, saved huge discharge hydraulic die cushion pump group, realizes reduction fever, result that is energy saving, reducing cost.
Figure of description：
Fig. 1 is the structure chart of this patent preferred embodiment；
Wherein：1, hydraulic cushion cylinder；2. prefill valve；3, hydraulic die cushion controls valve block；4, pressure sensor；5, accumulator；6, it stores
It can the safe valve group of device；7, hydraulic die cushion jacks up pump group；8, power fuel tank.
Specific implementation mode
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, it is described in detail such as
Under：
Referring to Fig. 1, a kind of energy-conserving hydraulic for hydraulic press pads control system, including：
Hydraulic cushion cylinder 1, prefill valve 2, hydraulic die cushion control valve block 3, pressure sensor 4, accumulator 5, the safe valve group of accumulator
6, hydraulic die cushion jacks up pump group 7, power fuel tank 8.
Wherein：Hydraulic die cushion is with the passive downlink of sliding block, and fluid is discharged into hydraulic die cushion control by prefill valve 2 in hydraulic cushion cylinder 1
It in valve block 3, then is discharged into accumulator 5 by pipeline, fluid passes through hydraulic die cushion and controls valve block 3 and reaches liquid in accumulator 5 when jack-up
In pressure pad cylinder 1, driving hydraulic die cushion jacks up, to achieve the purpose that final to make that hydraulic press is energy saving, reduces cost.
Above-mentioned technical proposal includes mainly hydraulic system power fuel tank, hydraulic die cushion jacks up pump group, hydraulic die cushion controls valve block,
Accumulator and for connecting fluid pressure line etc. everywhere.
The hydraulic die cushion control valve block 3 is placed on 8 top of power fuel tank, and hydraulic die cushion control valve block 3 connects liquid by oil pipe
Pressure pad cylinder 1 and accumulator 5, the hydraulic oil in hydraulic cushion cylinder 5 controls valve block 3 by hydraulic die cushion and is discharged into accumulator 5, by energy storage
Among accumulator, hydraulic die cushion jack-up is theoretically discharged into the oil of accumulator using the energy of accumulator when needing to jack up
Hydraulic die cushion can be just pushed to return to stretch position by liquid, use for the first time or generation fluid leakage loss situation utilizes small displacement hydraulic die cushion top
It plays pump group to realize and give accumulator ftercompction, fever, energy-efficient purpose is reduced to realize with this.
The working condition of above-mentioned technical proposal is as follows：
In hydraulic press drawing process, hydraulic die cushion is discharged into hydraulic die cushion control with slide block down, 1 fluid of hydraulic cushion cylinder by pipeline
In valve block 3 processed, hydraulic die cushion control valve block is discharged into after proportioning valve pressure regulation in accumulator 5, after the completion of pulling action, electromagnetic switch
Valve YA50 is powered under the control of electrical program, and the fluid in accumulator 5 controls valve block 3 by oil pipe and hydraulic die cushion and is discharged into hydraulic pressure
It pads in cylinder 1, hydraulic die cushion is made to jack up to stretch position, technological action cycle completion.For the first time using or system there are leakage losses
In the case of, 4 sender of pressure sensor, magnetic reversal valve YA51 is powered under the control of electrical program, and hydraulic die cushion jacks up pump group 7 to storage
Energy 5 repairing of device, after oil compensation pressure arrives, 4 sender of pressure sensor, ftercompction action is completed.Theoretically, the energy of accumulator storage is proper
Hydraulic die cushion can be pushed to return to well stretch position, for the first time after use, accumulator ftercompction need not be given again.According to actually detected, sheet
Scheme can make calorific value in hydraulic press drawing process reduce 1/3 or more, while save the cost that hydraulic die cushion jacks up pump group 80%,
And plant capacity is reduced, conventional hydraulic machine can be largely used to.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention,
