Abstract
The invention discloses a sealing device used for EDT electrode flushing. The sealing device comprises a base, a lug boss and an oil filling port. The sealing device is characterized in that the lug boss is 5mm high, so that sealing and embedding stability is guaranteed, and assembly is easy; and if the lug boss is too short, the stability is poor, and the lug boss is not beneficial for assembly if too long. During use, the lug boss is completely embedded into a hollow inner cavity surface with electrode thickness being L1 by utilizing elasticity of rubber; height of the base is L2, width of the upper surface of the base is L3, and the upper surface of the electrode is completely in contact with an outer ring surface with electrode width being L4; the width of the lower surface of the base is L5, and the lower surface of the base is in contact with an electrode clamping base; and the oil filling port of the base completely fits to an oil spraying port of the electrode clamping base, so that electrode flushing oil flow only can be sprayed out from the oil filling port during rough processing, and therefore, leakage of flushing oil flow is avoided, flushing pressure is guaranteed, and flushing effect is improved. The sealing device has the advantages of controlling flow direction of oil flushing very well, and improving flushing pressure data by 30% or more by adopting an O-shaped ring to seal.
Description
Technical field
The present invention relates to cold-rolling equipment technical field, more particularly, to a kind of sealing device for EDT electrode washing, this is different
Shape sealing avoids the leakage of EDT electrode oil product when rinsing, and can carry flushing pressure in the case of flushing pump parameter constant
High by 30%, it is to avoid the attachment to roll surface for metal fragment during texturing, eliminate annular black vaginal discharge during texturing.
Background technology
EDT electric spark unhairing machine is certain plant equipment German.The roll of texturing be mainly used in acid roll last frame, smooth,
Galvanization production line.Sometimes blackstreak along roll surface circumferencial direction occurs after roller texturing, blackstreak is to produce during texturing
Metal fragment and carbon granules, so that it is covered and formed in roller surface, the metal fragment of covering and carbon
Grain can impeded electrode corrode to the direct electric discharge of roll surface in texturing, leads to roller texturing bad generation when serious.
Electrode is hollow structure, and in texturing, insulation oil product sprays from the hollow position of electrode, the metal that roll surface is produced
Chip is washed away.Original design for O-ring structure.O-ring simply holds in the palm in electrode base, and in discharge process, electrode is in servoBcylinder
Driving under constantly close with roll surface（0.02-0.2mm）Generation until discharge process（Millisecond）, in next discharge process
Electrode still constantly close to roll surface until electric discharge produce, so from one instantaneously from the point of view of, servoBcylinder is in whole texturing process
In be constantly action, such process necessarily lead to hold in the palm be also easy to produce between the O-ring and electrode of bottom loosening, loosen draw
The gap risen can leak away the insulation rinsed oil product so that the oil product pressure spraying from hollow part is little, does not also reach flushing
The effect of roll surface.The bad roll of texturing can cause strip longitudinal chromatic aberration when reaching the standard grade and using, and reduces product quality.
Before making the present invention, once considered using the sealing of Y type, though because Y type sealing sealing effectiveness can ensure that, processing
Making property is very poor.Not only electrode end surface will be carried out with milling machining, and the sealing of Y type also need to be assemblied in electrode milling after recessed
Just can use in groove, use environment is unfriendly.In addition during actual fabrication, because electrode wall is relatively thin（Several millimeters）, such
Milling Process is carried out on electrode, then embeds the sealing of Y type again, such scheme is feasible, but manufacturing is not good, therefore abandons Y
The scheme of type sealing.For preventing the generation of O-ring and electrode base gap, in advance necessary change need to be applied to sealing, mainly
It is the version changing sealing.
Content of the invention
The purpose of the present invention is aiming at the problem of prior art presence, provides a kind of sealing for EDT electrode washing
Device, prevents during texturing the roll that annular black vaginal discharge leads to bad, it is to avoid the strip quality being led to due to texturing collars shape black vaginal discharge
Decline.
The principle of the present invention is originally simply to be ask the O-ring in electrode base to make Embedded structure, encapsulant into
Using oil resistant rubber, soft material, can be made full use of it there is the characteristic of larger elasticity, allow the embedded part of sealing can be with interference
Fully fit with electrode inner surface, bottom surface, it is to avoid rinse the leakage of oil product.
The object of the present invention is achieved like this：A kind of sealing device for EDT electrode washing, including base, boss
With pouring orifice it is characterised in that：The height of boss is 5mm, and this length ensures the embedded stability of sealing and is easily assembled, boss
The too short stability of length is poor, and length is long, is unfavorable for assembling；The elasticity of rubber is utilized, it is thick that boss is completely embedded into electrode during use
Spend the hollow cavity face for L1；The height of base is L2, and the upper surface width of base is the outer ring surface with electrode width for L4 for the L3
Completely attach to, the lower surface width of base is that L5 clamps base contacts with electrode；The pouring orifice of base and electrode Holding seat
Jet fits like a glove so that electrode washing oil stream can only spray from pouring orifice, thus avoiding flushing oil stream during texturing process
Leakage it is ensured that flushing pressure, improve developing result.
It is characterized in that：It is preferred that described L1, L2, L3, L4, L5 are respectively 37 mm, 3mm, 4mm, 4mm, 45mm.
It is characterized in that：The boss of special-shaped insert seal is embedded into the hollow position of electrode, using caulking gum material
Elasticity make it be attached to electrode inner surface, seal during texturing and be integrally formed with electrode, will not be because servoBcylinder be in wink
When constantly telescopic oscillating and lead to seal and electrode between gap generation.
It is characterized in that：The installation of special-shaped insert seal is extremely simple, and electrode end surface is not required, in use or more
Only electrode end surface need to be loaded in advance, even if this sealing when changing electrode still can be reused before changing electrode.
Compared with prior art, it is an advantage of the invention that：The flushing hole of center seal position preferably controls oil product punching
That washes flows to the flushing pressure difference uniformity it is ensured that each electrode, and flushing pressure improves more than 30%.Good sealing effect,
Easily make, prevented the attachment to roll surface for metal fragment during texturing.During test and comparison scouring effect, the flow of flushing pump is not
Become.By photo 1,2 as can be seen that having changed the scouring effect of special-shaped insert seal, it is close that liquid level lift is significantly better than O-ring
Envelope.
