Abstract
The capstan (202) cooling system is based on deflectable flaps (204) that are pressable against the inner surface of the capstan. The cooling system has the advantage that the flaps (204) skid on the coolant film at the operational speed and scrape the inner surface of the capstan (202) at start or stop speeds. In this way the inner surface of the capstan is cleaned from rust and other debris. At the operational speed, as the flaps skid on the coolant, there is very little loss in power due to friction.

Technical field
The present invention relates to one kind is applied to cooling system used in silk drawer's platform (bench), more particularly, to
The dry drawing work platform that a kind of wherein drawing capstan winch must be cooled in use.Present invention is equally related to one kind is provided with this
Silk drawer's platform of the cooling system of sample, and cooling system and the group being applied to the capstan winch being used together with described cooling system
Close.Additionally, a kind of the present invention relates to method for cooling down dry drawing capstan winch.
Background technology
In metal wire drawing, for example, it is drawn through in succession less by the tinsel that the metal of steel, copper, aluminum etc is made
The hole being made up of hard metal drawing mould.Drawing mould is installed to drawer's platform to prevent in firm die holder
Mould is moved together with silk.Silk is referred to as " drawing capstan winch " or abbreviation " capstan winch in the art by reel
(capstan) " it is pulled through mould, the filament winding of some circles this reel and is wound in order to silk of holding with a firm grip.In some circles
Afterwards, silk leaves capstan winch and is directed to next drawing mould and is eventually led to take-up reel.Certainly, silk must by lubrication in order to
Friction between silk and mould during reduction drawing.When lubrication is realized by the lubricant in the form of powder or gel,
It is referred to as " dry drawing ", and this is the wet type silk drawing being immersed in fluid lubricant with respect to mould, capstan winch and silk.
At each drawing mould, silk, by plastic deformation, thus generates amount of heat.Although in wet type silk drawing, should
Heat is easy to be passed to fluid lubricant, and in dry drawing, this is impossible.Therefore, in dry drawing, mould keeps
Device is cooled.The cooling of silk can be increased to a certain degree by increasing around the number of turns of capstan winch, but this only only reduces silk
Leave temperature, and do not improve the cooling entering winding.Therefore, the capstan winch receiving heated filament must also be cooled.Uncolled or
Insufficient cooling leads to inferior yarn quality.The cooling of capstan winch is therefore known asking in the design of dry drawing work platform
Topic.
Generally, cooling from the inside of capstan winch by coolant being sprayed on the inwall of capstan winch and the liquid bath under capstan winch
In again reclaim and be done.Alternatively, or in addition, air is cooled in coaming (sill) the place air of capstan winch from around strand
The position that the gap of disk is blown on silk is used multiple times.The coaming of capstan winch is the hoop at the foot of capstan winch, and it will exist
Winding upwardly.At this coaming, silk is the hottest.
Some replacement schemes announced and improvement are：
A, JP8281317A describe drawing capstan winch, and wherein static, inner cylinder is introduced into, and has the blade at top,
Its by cold water directivity inject between cylinder and the interior surface of capstan winch gap in.
B, EP0752287 describe the capstan winch with fluid cooling unit, and the latter includes that at least one is fan-shaped, its be located at
The inner transverse surface of main body close to place and is connected to the fixed frame of drawer's platform.Exist close to fan-shaped outer surface
At least one nozzle is in order to be formed at the sheath of the cooling liquid of flowing on the inner transverse surface of main body.Sector is provided with spiral shell
The fin of rotation orientation, its agitation cooling fluid in lateral surfaces internally.Relatively large service opening is necessarily placed at capstan winch
Top is in order to installing and being directed at sector.
C, US4050282 describe internal cooling system, are wherein inserted into part and have vertical, axially extended flank, and it will
In multiple individuality rooms, the gap between insert and capstan winch separates.Flank enters the arch freely strained of part positioned at circular interpolation
Or at bending section.Axially extended flank is with the little clearance less than 0.5mm, preferably smaller than 0.2mm before the inner surface of capstan winch
Terminate so that possible foreign material deposit is for good and all taken away by rotating drawing mould cylinder.
One problem of the cooling capacity of deterioration capstan winch is actually and forms rusty scale on the inside of capstan winch.Due to rusty scale shape
Become, the cooling capacity of internal cooling system is lowered.Because coolant flow keeps constant, this reduction of manyfold in cooling capacity
Carry out without being noticed.
Based on another problem is that (such as in prior art " A " and " C ") cooling system of narrow gap cooling occurs,
Pulled by capstan winch due to coolant and keep fixing by inner core, the viscosity of coolant leads to the disturbance occurring with high drawing speed
Loss.This is used for driving the power of capstan winch to have significant impact to needs.
Content of the invention
The primary and foremost purpose of the present invention is therefore to provide a kind of cooling system of the silk drawing capstan winch for dry drawing work platform,
Its ensure constant coolant activity efficient cooling and have low-power use.Inventor finds and finds a kind of cooling
System, it removes the inside rust of formation in a controlled manner, and the same time ensures the suitable of capstan winch when using less power
Cooling.And, cooling system can simply be installed and be allowed some leeway when mounted.Additionally, it is once mounted
Capstan winch internal it is not necessary to fine setting to cooling system.Therefore, cooling system can be with non-on existing dry drawing machine
Often little easily transformed even without the adaptation to capstan winch.It is a further object of the present invention to provide a kind of drawer's platform,
It is adapted to improved cooling system.Further it is provided that a kind of method of the capstan winch of cooling dry drawing work platform.
According to the first aspect of the invention it is proposed that a kind of cooling system of the capstan winch for silk drawer's platform.Capstan winch quilt
It is rotatably mounted to drawer's platform.Capstan winch has inwall, this inwall silk drawing capstan winch axial length at least part of on
With surface of revolution.Silk drawer's platform that cooling system will be fixedly secured in the inside of described capstan winch.
Cooling system specifically includes carrier and multiple deflection fin.Have " deflection fin " mean its edge,
The sheet material at one of side or end place is installed to carrier：" carrier edge ".Another opposite edges of deflection fin, side
Face or end are compressible, i.e. have the ability being pressed against the surface of the inwall of capstan winch installing cooling system, and will be claimed
For " pressurized edge ".Installing of deflection fin makes fin during use be bent in the direction of rotation of capstan winch.This is scratched
The bent directly contact disconnecting between pressurized edge and the inwall of capstan winch.When the rotation of capstan winch is stopped, pressurized EDGE CONTACT twists
The inwall of disk.
Preferably, when being installed, fin forms the sharp angle of wedge with the surface of inwall.This angle of wedge is perpendicular to contact line
Plane in angle between deflection fin and the surface of inwall.This contact line is that pressurized edge is in static phase with inwall
The line met.The angle of wedge is at an acute angle along contact line.Contact line is preferably continuous, that is, when being in static, pressurized edge is in the wing
The inwall of capstan winch is contacted on the whole length of piece.There is not substantive gap between pressurized edge and inwall.
The inwall that can be contacted with one or more fins is had as at least a portion of the axial length of capstan winch
Surface of revolution surface.Outside this part, surface simultaneously needs not be surface of revolution, for example, there is spoke to pacify capstan winch
In place of being attached to driving axis." surface of revolution " is the surface being formed by the axis Plane of rotation curve in plane.Here,
The rotation axiss on this surface are substantially coincident with the rotation axiss of capstan winch.Although this curve can be any plane curve, it is excellent
Choosing is such as substantially linear etc simple, smoothed curve.So, surface of revolution is taper, or when line is parallel to rotation
It is cylindricality during axis.Preferably, the surface of inwall is smooth, when not there are usual (for example seeing EP0752287)
Circumferential groove or ridge.
The carrier that deflection fin is installed to thereon can be to have crutched flange, and an edge of fin is mounted
To this pillar.Alternately, carrier can be sleeve pipe, and the live axle of capstan winch rotates wherein.
Coolant can apply to any fluid of this purpose.For example, it can be the gas of such as forced air.?
Should in the case of, single coolant delivery apparatus can not be necessary, and capstan winch can be existed inside capstan winch in theory
Air cools down.Certainly, the most water as coolant potentially includes cleaning agent to prevent from being constituted foam or to be formed rotten
Erosion will be preferably as it cheaply and easily obtains, but also have good cooling capacity.
Therefore, in another preferred embodiment, cooling system also includes one or more coolant supplies for feedback
Send coolant.Coolant supply is directed and can spray cooling on the surface of the inner shell or only on fin or towards both
Agent.Preferably, coolant supply is directed to inject coolant to the sharp angle of wedge between deflection fin and inwall.Coolant
The number of supply can be different from the number of fin, and such as each fin joins two supplies.Coolant supply can be by
On the inside non-rotating part of the drawer's platform being arranged on the sleeve pipe being such as exemplified as live axle, or may be attached to load
Body, the latter is it is furthermore preferred that because the direction sprayed at that rate can be set on carrier together with the installation of fin.More excellent
Choosing, each fin has the coolant supply in the first half being likely located at fin of its association.
In a further preferred embodiment, deflection fin contact with the surface of inwall line pressure makes：
Be in capstan winch speed of operation when, coolant during the fixing working condition of silk drawer's platform
Thin film is formed between fin and this surface, and that is, fin skids (skid) in cooling agent film upper fluid power.
It is in and slow rise when (ramp up) when capstan winch starts rotation or be in slow fall (ramp down)
When winch reductor when stopping completely fin swipe inwall surface.
For the purpose of the application, there is the fin backup inwall that " contact line pressure " means the length allocation of touched line
Total power.
The work of cooling device is based on the conversion from boundary lubrication condition to hydrodynamic lubrication.
When being in low speed (and/or when being in high contact line pressure), the thickness due to cooling down agent film is less than the table of inwall
Face or the maximal roughness at pressurized edge, the micro-bulge friction of contact surface, scraping are each other.This be boundary lubrication condition and its
The feature with great friction coefficient (i.e. high energy losses) and the abrasion increasing contact surface.Although this state is typically detested
Dislike, it rises to state velocity and slow being down to stops completely slow at least for the controlled time period in this case
Period is favourable.During those short time periods, the pressurized edge of fin by the surface of inwall of swiping, and thus
Remove any foreign material of the rust being such as exemplified as being likely to form and suppress the cooling of capstan winch or other deposits.
When the relative velocity between fin and inwall is gradually increased, lubricating status pass through dynamic from boundary lubrication to fluid
The transition of hydrodynamic lubrication.
Be in during high speed and/or be in low contact line pressure when, the pressurized edge of fin skid on coolant and
Cooling agent film against the surface of inwall is formed.The thickness of the thin film being formed is now than the contact surface two of fin and inwall
Total roughness of person is much bigger.Friction because physical contact between the surfaces is disconnected, between fin and inwall
Greatly reduced, lead to lower power to use.And, because water thin film no longer with contact internal walls, disturbance loss greatly subtracted
Little and only coolant clash into fin when occur.
Conversion between different conditions generally by this Trebek (Stribeck) curve describe, wherein fin with interior
Friction between wall is plotted as the letter of the dimensionless bearing characteristic number of the viscosity × speed/contact line pressure equal to coolant
Number.For the purpose of the application, the viscosity of coolant makes turning from boundary lubrication to hydrodynamic state with contacting line pressure
Change and preferably take place between 200 and 600m/min.
Important design parameter is the sharp angle of wedge further.Preferably, this angle of wedge (is including at 0 ° in the length of contact line
Zero) with less than 45 ° in the range of.Involved tribology similar to the tribology of plain besring, wherein it is known that being existed by fluid
The maximum pressure applying on fin increases with respect to angle of wedge inverse ratio, leads to low-angle to be in the big power on fin, i.e. fin exists
It is highly susceptible to when the angle of wedge is less being lifted.When the then curve of the inside of fin and the surface of revolution of inwall in fin by flanging
At edge tangent when (first derivative on fin curve and surface and zero equal in this edge), little or zero degree is obtained.Should " the wing
The inside of piece " is the side towards the sharp angle of wedge.So, if angle is sufficiently small, fin will always from surface lifting, even if in
Even if uniform velocity and at high contact line pressure.Therefore, too small angle may result in inwall when being in beginning or stopping
Insufficient scraping.Therefore, from 1 ° to 30 ° or 5 ° to 20 ° or selection that even 5 ° to 15 ° of the sharp angle of wedge has been.The sharp angle of wedge is permissible
The length of contact line changes in the range of those.
In a further preferred embodiment, the number of fin is between one and 24.When being in fully high speed
One fin may be enough, because coolant is not only distributed by the action of fin, also by the centrifugation of the rotation generation due to capstan winch
Power and be held against inwall.These can simply reach 10 to 20g (" g " is acceleration of gravity).Thin in order to obtain coolant
The abundant distribution of film is it may be considered that use such as up to as many as 24 fin.Each additional fin increases the disturbance of coolant,
Thus stir coolant, increased the cooling capacity of system.However, each fin will contribute to the dragging of coolant and therefore will
Increase power to use.Additionally, more fins increase the cost of system.So the fin between 2 and 6 is optimal value.
It is contemplated that two decision design for fin.
In a preferred embodiment, fin is rigid and can not be bent easily.They have the carrier of hinge
Edge is installed to carrier in order to make fin deflection.So that fin can be pressed against the inwall of capstan winch, spring part is pacified
It is contained between carrier and fin.Such spring part can be leaf spring or helical spring, or can have such as rubber spring or
Any other elastomeric material of air spring etc is made.It is possible that hinge and spring can be in the single curved bels of material
In be combined, such as spring steel band.The steel of this band has high yield stress in order to resisting deformation and easily returning it
Original-shape.
In alternative preferred embodiment, fin is flexible in itself but carrier edge is rigidly mounted to carrier.By
In its bending, fin subsequently generates the pressure against inwall.Fin can be made up of suitable, flexibility material, such as metal.
Preferably metal is, for example, rustless steel or spring steel, aluminum (duralumin) or copper alloy.The high yield strength of metal is excellent for elastic force
Choosing.Alternative material such as polyamide, the high performance plastics of polyurethane or even vulcanite etc can be considered.
The contact line pressure being applied on the surface of the inner shell by fin is preferably between 10 and 1000N/m, or between 15
And 500N/m between or even between 20 and 200N/m.These scopes are changed with the angle of wedge one.For example, there is the little angle of wedge,
High contact line pressure can be used, and has the larger angle of wedge, and relatively low contact line pressure is necessarily applied in order to allow fin
Coolant skids.
In a further preferred embodiment, fin is in pressurized edge, you can be pressed against the edge of the inwall of described capstan winch
Place is provided with touch-down zone.Touch-down zone is in the region of the pressurized edge of fin, itself and be also not only in one fixed width on line
Above contact with the inner surface of static capstan winch.That is, the shape on surface is followed in touch-down zone.This touch-down zone can be during the use extending
Formed, because fin is gradually formed the edge of fin with swiping of the surface of inwall with the shape on the surface of inwall.Alternative
Ground, the edge of fin can be started anew to be arranged in touch-down zone.Touch-down zone can be replaceable with such as metal or plastics
The form of wearing part is set, and this part can be pressed from both sides, end that is sliding or being fastened to fin.
In a preferred embodiment, this touch-down zone can be provided with wear-resistant and/or abrasive coating.Such coating for example may be used
Can be led to including grinding and/or wear-resistant granule, such as quartz, carborundum, cubic boron nitride or tungsten carbide, and this coating
Cross paint or cladding (such as laser melting coating) and be applied in.Alternately, grind and/or wear-resistant granule can be incorporated into can
Replace in wearing part.The function of coating or wearing part is used for ensureing that the surface of inwall is rightly cleaned and scraped on the one hand
Wipe and be used on the other hand to prevent the quick-wearing excessively of flap edges.The surface roughness of wearing part or coating additionally aids
Agitation cools down agent film and improves the cooling of system.
In a further embodiment, fin is installed to be the rotation axiss being arranged essentially parallel to capstan winch.More specifically：Connect
Tactile line is substantially in including the plane of rotation axiss of capstan winch.
Alternately, fin can tilt with respect to the rotation axiss of capstan winch.That is, it is met in described fin and described surface
The line at place is substantially in the plane with respect to the inclined angle of the rotation axiss of capstan winch.Advantageously, this inclination makes in capstan winch
Rotation during, coolant is driven to respect to the direction of gravity.In this way, the flowing downward to a certain degree of fluid
On be cancelled, and refrigerant distribution evenly on inwall can be obtained.This angle of inclination can be at 1 ° up to even 60 °
Between, more electedly between 1 ° and 20 ° or between 5 ° and 15 °.
Specifically, it is preferred embodiment when the surface of revolution of inwall is frustum of a cone or cylinder.When fin is including
When in the plane of the axis of capstan winch, contact line will be the straight line tilting with respect to capstan winch axis (circular cone) or will be parallel to twist
The straight line of disk axis (cylinder).In the case that fin tilts with respect to the axis of capstan winch, contact line will be to be with surface of revolution
No be frusto-conical or the unrelated ellipse of cylinder part.Frusto-conical is above the plane at an angle with the axis of cone
The cone that has been removed of top.
According to the second aspect of the invention, cooling system is provided with combining of capstan winch.Cooling system is according to the present invention

120 by the drawing with the speed required by drawing process of motor (not shown).Inside capstan winch, cylinder internal coolant
Keeping wall 107 is mounted, and thus reserves small-gap suture between keeping wall 107 and capstan winch 102.Coolant passes through coolant feed-through device
110 are supplied in this gap on the direction being indicated by flow arrow 116.There is coolant seals part at the bottom of capstan winch
105 leak out gap to prevent coolant.After internally flowing through in coolant keeping wall, coolant is in the bottom of drawing capstan winch
Place is collected and is extracted by coolant extraction tube 112.The heated filament 106 entering passes through the action of coaming 108 by
The multi-turn silk existing pushes up.After having made some circles, cooling silk 106' leaves capstan winch to enter next drawing die
Have or be wrapped on spool.
This design has the shortcomings that some are serious：In the coolant in gap, when being especially in high speed, power consumption
Agitation can occur.And, at the inside that capstan winch 102 is contacted with coolant, outside such as rust or other deposits etc
Carry out material to be formed.These deposits have the adverse effect to the heat transfer from capstan winch to coolant, thus reduce in time
The cooling capacity of system.Because cooling capacity reduces, more coolants (such as water) must be supplied, otherwise the quality of silk by
It is lowered in cooling deficiency.
Show in fig. 2 a and according to the first embodiment of the present invention 200.Fig. 2 b shows along " I-I " in Fig. 2 a
The capstan winch of plane indicating and the cross section of cooling system.Again, heated filament 206 enters capstan winch at coaming 208, and

It is fixed on wheel shaft 220, this wheel shaft 220 is rotatably installed in axle casing 222 by bearing 226 on work platform 214
In.It is based on carrier rings 223 from cooling system unlike existing embodiment, this carrier rings 223 is fixed with stake or pillar
213 is three in this case.Fin (flap) 204 is installed to each stake 213.By coolant feed-through device 210, cold
But agent is distributed to three coolant feed-through pipes 218 being sprayed on coolant by nozzle 211 on the inwall of capstan winch 202.Capstan winch
202 inwall at least has surface of revolution 203 on axial length " L ", contacts with fin 204 in this place.With this curved face contact
Fin 204' edge by Fig. 2 a line " A " indicate.It is noted that in this embodiment, line " A " is in including capstan winch
In the plane of rotation axiss.Coolant is collected in the liquid bath 217 be installed to work platform 214 and passes through coolant extractor
212 discharges.Because being no longer necessary to sealing ring, there is not the power loss causing due to the friction of such sealing member.
In this particular example, each fin 204 is fabricated from a flexible material, and it is at their stake 213 by rigidly
It is connected to carrier.Fin is for example made up of the thick corrosion resistant plate of 0.8 to 1.0mm.Alternative material is the aluminium sheet of 1.5mm.The wing
Piece is at least flexure during use in the direction of rotation 219 of capstan winch.At the other edge of fin fin with interior
The angle that the surface of revolution place of meeting of wall is formed is the angle of wedge " α ", and it is about 15 ° in this case.Fin is pressed against capstan winch
Total power of 202 inwall is in the length of 20cm between 20 to 30 Ns.This combination of contact line pressure and the angle of wedge makes
Fin skids forward from the speed of about 100m/min on water coolant.Below this speed, water coolant film breaks are simultaneously
And the inwall of edge " A " the scraping capstan winch of fin, thus removing and clean may established any deposit (such as becoming rusty).Remove
This exterior piece contributes to reducing the speed of capstan winch, i.e. as additional braking.
