Description

Cooling system for dry drawing capstan winch

Technical field

The present invention relates to a kind of cooling system suitable for being used silk drawer platform (bench), more particularly, to A kind of dry drawing work platform that wherein drawing capstan winch must be cooled in use.Present invention is equally related to one kind being provided with this The silk drawer platform and cooling system of the cooling system of sample and the group of the capstan winch suitable for being used together with the cooling system It closes.In addition, the present invention relates to a kind of methods for cooling down dry drawing capstan winch.

Background technology

In metal wire drawing, such as the wire made of the metal of steel, copper, aluminium etc is drawn through successive smaller The hole made of hard metal drawing mould.Drawing mould is mounted to drawer's platform to prevent in firm die holder Mold is moved together with silk.Silk is by reel --- it is referred to as " drawing capstan winch " or referred to as " capstan winch in the art (capstan) " --- it is pulled through mold, the filament winding of several circles the reel and is wound in order to silk of holding with a firm grip.In several circles Afterwards, silk leaves capstan winch and is directed to next drawing mould and is eventually led to take-up reel.Certainly, silk must be lubricated in order to Friction during reduction drawing between silk and mold.When lubrication is realized by the lubricant in the form of powder or gel, It is referred to as " dry drawing ", this is the wet type silk drawing being immersed in relative to mold, capstan winch and silk in fluid lubricant.

At each drawing mould, silk thus generates amount of heat by plastic deformation.Although, should in wet type silk drawing Heat is easy to be passed to fluid lubricant, this is impossible in dry drawing.Therefore, mold is kept in dry drawing 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 into winding.Therefore, receiving the capstan winch of heated filament must also be cooled.It is uncolled or Insufficient cooling leads to inferior yarn quality.Therefore the cooling of capstan winch is known ask in the design of dry drawing work platform Topic.

In general, cooling pass through the liquid bath that is sprayed on coolant on the inner wall of capstan winch and under capstan winch from the inside of capstan winch In recycle and be completed again.Alternatively, or in addition, air cooling at the coaming (sill) of capstan winch air from around strand It blows the position on silk and is used multiple times in the gap of disk.The coaming of capstan winch is the hoop at the foot of capstan winch, will be had existed Winding push up.Silk is most hot at the coaming.

Some alternative solutions announced and improvement are：

A, JP8281317A describes drawing capstan winch, wherein static, inner cylinder is introduced into, has the blade at top, It injects cold water directionality in the gap between cylinder and the interior surface of capstan winch.

B, EP0752287 describes the capstan winch with fluid cooling unit, and the latter includes at least one sector, be located at The inner transverse surface of main body is 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 being formed in the sheath of the cooling liquid flowed on the inner transverse surface of main body.Sector is provided with spiral shell The fin of orientation is revolved, the cooling fluid in internal lateral surfaces is stirred.Relatively large service opening is necessarily placed at capstan winch Top is in order to installing and be aligned sector.

C, US4050282 describes internal cooling system, wherein interior insertion piece has vertical, axially extending flank, it will Gap in multiple individual rooms between insertion piece and capstan winch separates.Flank is located at the arch freely tensed that circular interpolation enters part Or at bending section.Axially extending flank is with the small clearance less than 0.5mm, preferably smaller than 0.2mm before the inner surface of capstan winch It terminates so that possible foreign material deposit is for good and all taken away by rotating drawing mould cylinder.

A problem for deteriorating the cooling capacity of capstan winch is actually to form rusty scale on the inside of capstan winch.Due to rusty scale shape At the cooling capacity of internal cooling system is lowered.Since coolant flow is kept constant, reduction of manyfold in cooling capacity It carries out without being noticed.

Based on narrow gap cooling (such as in the prior art " A " and " C ") cooling system generation another problem is that, Since coolant is pulled by capstan winch and is kept fixed by inner cylinder, the viscosity of coolant leads to the disturbance occurred with high drawing speed Loss.This has significant impact to the power for needing to be used for driving capstan winch.

Invention content

Therefore the primary and foremost purpose of the present invention is to provide a kind of cooling system of the silk drawing capstan winch for dry drawing work platform, It ensures to use in the efficient cooling of constant coolant activity and with low-power.Inventor finds and finds a kind of cooling System removes the inside rust of formation in a controlled manner, and the same time ensures the appropriate of capstan winch when using less power It is cooling.Moreover, cooling system can be installed simply and allow some leeway when mounted.In addition, being once mounted It, need not be to the fine tuning of cooling system inside capstan winch.Therefore, cooling system can be on existing dry drawing machine with non- It is often small to be 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 capstan winch for silk drawer's platform.Capstan winch quilt It is rotatably mounted to drawer's platform.Capstan winch have inner wall, the inner wall silk drawing capstan winch axial length at least partially With surface of revolution.Cooling system will be in silk drawer's platform that the inside of the capstan winch is fixedly secured to.

Cooling system specifically includes carrier and multiple deflection fins.With " deflection fin " mean its edge, The plank at one of side or end place is mounted to carrier：" carrier edge ".Another opposite edges of deflection fin, side Face or end are compressible, that is, have the ability on the surface of the inner wall for the capstan winch for being pressed against installation cooling system, and will be claimed For " compression edge ".The installation of deflection fin is so that fin is bent on the direction of rotation of capstan winch during use.This is scratched Song disconnects being in direct contact between compression edge and the inner wall of capstan winch.When the rotation of capstan winch is stopped, compression EDGE CONTACT twists The inner wall of disk.

Preferably, when being installed, fin forms the sharp angle of wedge with the surface of inner wall.The angle of wedge is perpendicular to contact line Plane in angle between deflection fin and the surface of inner wall.The contact line is that compression edge is in static phase with inner wall The line of chance.The angle of wedge is at an acute angle along contact line.Contact line is preferably continuous, that is, compression edge is in the wing when being in static The inner wall of capstan winch is contacted in the whole length of piece.There is no substantive gaps between compression edge and inner wall.

The inner wall that can be contacted with one or more fins has as at least part of the axial length of capstan winch Surface of revolution surface.Except the part, surface does not need to be surface of revolution, such as there are spokes to pacify capstan winch It is attached in place of driving axis." surface of revolution " is the surface formed by the axis Plane of rotation curve in plane.Here, The rotation axis on the surface and the rotation axis of capstan winch are substantially coincident.Although the curve can be any plane curve, excellent Choosing is such as substantially simple, smoothed curve of straight line etc.So, surface of revolution is taper, or when line is parallel to rotation It is cylindrical when axis.Preferably, the surface of inner wall is smooth, that is, sometimes usual (such as seeing EP0752287) is not present Circumferential groove or ridge.

It can be the crutched flange of tool that deflection fin, which is mounted to carrier thereon, and an edge of fin is mounted To the pillar.Alternatively, carrier can be casing, wherein the drive shaft rotation of capstan winch.

Coolant can be any fluid suitable for the purpose.For example, it can be the gas of such as forced air.? In this case, individually coolant delivery apparatus can not be necessary, and theoretically capstan winch can be existing for inside capstan winch Air cooling.Certainly, as most water of coolant --- may include that detergent is rotten to prevent from being constituted foam or formation Erosion --- will be preferably as it is cheap and be easy to obtain, but also has good cooling capacity.

Therefore, in another preferred embodiment, cooling system further includes one or more coolant power supply units for feedback Send coolant.Coolant power supply unit is guided and can spray cooling on the surface of the inner shell or only on fin or towards the two Agent.Preferably, coolant power supply unit is directed to inject coolant to the sharp angle of wedge between deflection fin and inner wall.Coolant The number of power supply unit can be different from the number of fin, such as each fin matches two power supply units.Coolant power supply unit can be by It is arranged on the inside non-rotating part for the drawer's platform for being such as exemplified as the casing of drive shaft, or may be attached to load Body, the latter are it is furthermore preferred that because the direction sprayed at that rate can be set at together with the installation of fin on carrier.It is more excellent Choosing, each fin have its associated coolant power supply unit being likely located in the first half of fin.

In a further preferred embodiment, deflection fin makes with the contact line pressure on the surface of inner wall：

--- that is, during fixation working condition of silk drawer's platform --- coolant when service speed in capstan winch Film is formed between fin and the surface, i.e., fin skids (skid) in cooling agent film upper fluid power.

When in slow liter (ramp up) --- when capstan winch starts rotation --- or in slow drop (ramp down) When --- when winch reductor when stopping completely --- fin scrape inner wall surface.

For the purpose of the application, there is " contact line pressure " to mean by the fin backup inner wall of the length allocation of contact line Total power.

The work of cooling equipment is based on the conversion from boundary lubrication condition to hydrodynamic lubrication.

When in low speed (and/or when in high contact line pressure), since the thickness of cooling agent film is less than the table of inner wall The maximal roughness in face or compression edge, the micro-bulge friction of contact surface scrape each other.This be boundary lubrication condition and its Feature with great friction coefficient (i.e. high energy losses) and the abrasion for increasing contact surface.Although the state is typically to detest Dislike, it is at least for the controlled period in this case --- i.e. raise to state velocity and delay be down to complete stopping Period --- it is advantageous.During those short periods, the compression edge of fin will scrape the surface of inner wall, and thus Removal is such as exemplified as being likely to form and inhibiting the rust of the cooling of capstan winch or any foreign material of other deposits.

When the relative velocity between fin and inner wall gradually increases, lubricating status from boundary lubrication to fluid by moving The transition of hydrodynamic lubrication.

When in high speed and/or in low contact line pressure when, the compression edge of fin skid on coolant and Cooling agent film against the surface of inner wall is formed.The thickness of film is formed by now than the contact surface two of fin and inner wall Total roughness of person is much bigger.Because physical contact between the surfaces is disconnected, the friction between fin and inner wall It is greatly reduced, lower power is caused to use.Moreover, because water film is no longer contacted with inner wall, disturbance loss is greatly subtracted It is small and only coolant hit fin when occur.

Conversion between different conditions is usually described by this Trebek (Stribeck) curve, wherein fin with it is interior Friction between wall is plotted as the letter of the dimensionless bearing characteristic number of viscosity × speed/contact line pressure equal to coolant Number.For the purpose of the application, the viscosity and contact line pressure of coolant to turn from boundary lubrication to computational fluid dynamics state Change preferably takes place between 200 and 600m/min.

Further important design parameter is the sharp angle of wedge.Preferably, the angle of wedge in the length in contact line 0 ° (including Zero) and it is less than in the range of 45 °.Involved tribology is similar to the tribology of plain besring, wherein it is known that being existed by fluid The maximum pressure applied on fin increases relative to angle of wedge inverse ratio, causes low-angle to be in the big power on fin, that is, fin exists It is highly susceptible to being lifted when the angle of wedge is smaller.When the then curve and inner wall of the inside of fin surface of revolution in fin by flanging When tangent at edge (first derivative on fin curve and surface and zero equal in the edge), small or zero degree is obtained.It should " the wing The inside of piece " is towards the side of the sharp angle of wedge.So if angle is sufficiently small, fin will be lifted from surface always, even if in Uniform velocity and even if height contact line pressure at.Therefore, too small angle can cause in inner wall when starting or stopping Insufficient scraping.Therefore, from 1 ° to 30 ° or selection that 5 ° to 20 ° or even 5 ° to 15 ° of the sharp angle of wedge has been.The sharp angle of wedge can be with Change within the scope of those in the length of contact line.

In a further preferred embodiment, the number of fin is between one and 24.When in very high speed One fin may enough, because coolant is not only distributed by the action of fin, the centrifugation also generated by the rotation due to capstan winch Power and be held against inner wall.These can simply reach 10 to 20g (" g " is acceleration of gravity).It is thin in order to obtain coolant The abundant distribution of film, it may be considered that use such as up to as many as 24 fin.Each additional fin increases the disturbance of coolant, Thus coolant is stirred, the cooling capacity of system is increased.However, each fin will contribute to the dragging of coolant and therefore will Increase power to use.In addition, more fins increase the cost of system.So the fin between 2 and 6 is optimal value.

It is contemplated that being directed to two preferred designs of fin.

In a preferred embodiment, fin is rigid and cannot be bent easily.They are in the carrier with hinge Edge is mounted to carrier in order to make fin deflection.In order to enable fin can be pressed against the inner wall of capstan winch, spring part is pacified Between carrier and fin.Such spring part can be leaf spring or helical spring, or can have a such as rubber spring or Any other elastic 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 resist deformation and easily return to it Original-shape.

In alternative preferred embodiment, fin itself is flexible but carrier edge is rigidly mounted to carrier.By In its bending, fin subsequently generates the pressure against inner wall.Fin can be made of be suitble to, material flexible, such as metal. Preferred metal is, for example, stainless steel or spring steel, aluminium (duralumin) or copper alloy.The high yield strength of metal is excellent for elastic force Choosing.It can be considered such as the alternative material of polyamide, the high performance plastics of polyurethane or even vulcanized rubber etc.

The contact line pressure applied on the surface of the inner shell by fin is preferably between 10 and 1000N/m, or between 15 Between 500N/m or even between 20 and 200N/m.These ranges change with the angle of wedge one.For example, there is the small angle of wedge, Height contact line pressure can be used, and have the larger angle of wedge, and relatively low contact line pressure is necessarily applied in order to allow fin It skids on coolant.

In a further preferred embodiment, fin is in compression edge, you can is pressed against the edge of the inner wall of the capstan winch Place is provided with touch-down zone.Touch-down zone be in the region of the compression edge of fin, and not only on line be also in one fixed width It is upper to be contacted with the inner surface of static capstan winch.That is, touch-down zone follows the shape on surface.The touch-down zone can it is extended during use It is formed, because the scraping on the surface of fin and inner wall will gradually form the edge of fin with the shape on the surface of inner wall.It is alternative Ground, touch-down zone can be arranged from the beginning in the edge of fin.It touch-down zone can be with the replaceable of such as metal or plastics The form of wearing part is set, which can be by folder, cunning or the end for being fastened to fin.

In a preferred embodiment, which can be provided with wear-resistant and/or abrasive coating.Such coating for example may be used To include grinding and/or wear-resistant particle, such as quartz, silicon carbide, cubic boron nitride or tungsten carbide, and the coating can lead to It crosses paint or cladding (such as laser melting coating) and is applied in.Alternatively, can be incorporated into can for grinding and/or wear-resistant particle It replaces in wearing part.The function of coating or wearing part is used for ensureing that the surface of inner wall is properly cleaned and scraped on the one hand Wipe and be used for preventing on the other hand the quick-wearing excessively of flap edges.The surface roughness of wearing part or coating additionally aids The cooling agent film of agitation and the cooling for improving system.

In a further embodiment, fin is installed to be the rotation axis for being arranged essentially parallel to capstan winch.More specifically：It connects Tactile line is substantially in the plane of the rotation axis including capstan winch.

Alternatively, fin can be tilted relative to the rotation axis of capstan winch.That is, it is met in the fin and the surface The line at place is substantially in the plane relative to the inclined angle of the rotation axis of capstan winch.Advantageously, which makes in capstan winch Rotation during, coolant is driven to relative to the direction of gravity.By this method, fluid flows downward to a certain degree On be cancelled, and the refrigerant distribution on inner wall evenly can be obtained.It the 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 inner wall is frustum of a cone or cylinder.When fin including When in the plane of the axis of capstan winch, contact line will relative to the inclined straight line of capstan winch axis (circular cone) or will be parallel to twist The straight line of disk axis (cylinder).Inclined relative to the axis of capstan winch in fin, contact line will be with surface of revolution No is frusto-conical or the unrelated elliptical part of cylinder.Frusto-conical is above the plane at an angle with the axis of cone The removed cone in top.

According to the second aspect of the invention, the combination of cooling system and capstan winch is provided.Cooling system is according to the present invention First aspect described in cooling system.Capstan winch is adapted to be to work together with cooling system, the wherein rotation of the inner wall of capstan winch Turn surface and radius forms foregoing correct contact line pressure and the angle of wedge.It considers every possible angle, the outer diameter of capstan winch is usually in 200mm To between 1200mm, but mostly in 380mm between 620mm.

Capstan winch can be easily mounted on cooling system, because as capstan winch drops on installed cooling system Low, fin can be formed radially to bend.Single cooling system can be used in the range of capstan diameter, as long as It is satisfied for the condition of the angle of wedge and contact line pressure.In addition, the installation of cooling system does not need to high concentricity requirement, because Fin will adjust their obliquity if cooling film has been formed.Even coolant can be added in some degree of eccentricitys Agitation.Compared with must highly precisely be installed and need after mounting the later stage adjust the prior art system for this It is huge advantage.Therefore, cooling system of the invention can be easily transformed from existing apparatus, be put down if the inner wall of capstan winch has Sliding surface of revolution.Once cooling system is installed in capstan winch, there is no need to make fine tuning to cooling system.

In a further preferred embodiment, in the combination, the inner wall of capstan winch has recessed surface of revolution, cooling system Fin advance wherein.Such recessed surfaces help to keep coolant in place of needs：Heated filament contacts the circle at capstan winch All regions.

According to the third aspect of the invention we, it is desirable that protection a kind of drawer's platform comprising it is at least one according to it is any with The upper cooling system.Moreover, the silk drawer platform of at least one specific combination with capstan winch and cooling system is also wanted Ask protection.As silk diameter reduces, the follow-up capstan winch on silk drawer's platform is advanced with progressive higher peripheral speed.Because cold But energy is especially saved when the combination of system and capstan winch is in higher gait of march, which, which is directed to, is in those higher speeds The capstan winch of Shi Hangjin can be advantageously used.

According to the fourth aspect of the invention, a kind of method of the capstan winch of cooling silk drawer platform is described.This method includes Following steps：

Silk drawer's platform is provided, has the one or more installed on it is optional to turn capstan winch；

There is at least one of capstan winch capstan winch inner wall, the inner wall to be at least part of the axial length of capstan winch Surface of revolution.

One or more fins are provided at the inside of at least one capstan winch, wherein fin is deflection, and

Wherein an edge of the fin in their edge is mounted to the fixed part of the inside of the capstan winch, with And

Wherein fin can be pressed against the surface of revolution of the inner wall of capstan winch at their other edge；It is characterized in that,

During use, fin is bent on the intention direction of rotation of capstan winch, the wing being thus formed at other edge The angle of wedge between piece and surface of revolution.The angle of wedge is acute angle.

Another advantageous manner for implementing this method further comprises the steps：

Airfoil and/or surface supply coolant so that cool down agent film in the service speed of capstan winch and be formed in the wing Between piece and surface.

During the gentle drop of slow liter of capstan winch, the supply of coolant can remain so that fin is scraped in the presence of coolant Wipe the surface of inner wall.

In the additional embodiment of this method, following steps are added：

The supply of coolant is closed during the slow liter of capstan winch or slow drop, wherein fin scrapes the surface of inner wall.

The supplementary features of the embodiment of first, second, and third aspect according to the present invention can similarly be implemented into this In inventive method.

Specific implementation mode

In Fig. 1 with 100 instruction be silk drawer's platform with existing cooling system capstan winch.On work platform 114 at Different capstan winches is installed to row, there is drawing mould retainer (not shown) between capstan winch.Capstan winch 102 passes through fixing bolt 124 are secured to wheel shaft 120.Wheel shaft 120 is rotatably installed on the bearing 126 on the top of axle casing 122.Wheel shaft 120 by motor (not shown) with the drawing by the speed required by drawing process.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 on the direction indicated by flow arrow 116 in the gap.There are coolant seals parts at the bottom of capstan winch 105 to prevent coolant from leaking out gap.After being flowed through in internal 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 of entrance will by the action of coaming 108 Existing multi-turn silk pushes up.After having made some circles, cooling silk 106' leaves capstan winch to enter next drawing die Have or is wrapped on spool.

The design has the shortcomings that some are serious：In the coolant in gap, when being especially in high speed, power is consumed Agitation can occur.Moreover, at the inside of capstan winch 102 contacted with coolant, outside such as rust or other deposits etc Carry out material to be formed.These deposits have the adverse effect transmitted to the heat from capstan winch to coolant, thus reduce at any time The cooling capacity of system.Since cooling capacity reduces, more coolants (such as water) must be supplied, otherwise the quality of silk by It is lowered in cooling deficiency.

It shows in fig. 2 a and first embodiment 200 according to the invention.Fig. 2 b are shown along " I-I " in Fig. 2 a The capstan winch of the plane of instruction and the cross section of cooling system.Again, heated filament 206 enters capstan winch at coaming 208, and It is pushed upwardly, until it leaves capstan winch 202 at 206' with cold state.As previously mentioned, capstan winch 202 passes through fixing bolt 224 It is fixed on wheel shaft 220, which is rotatably installed in axle casing 222 on work platform 214 by bearing 226 In.Cooling system is based on carrier rings 223 unlike existing embodiment, and stake or pillar are fixed in the carrier rings 223 213 --- it is three in this case.Fin (flap) 204 is mounted to each stake 213.It is cold by coolant feed-through device 210 But agent is distributed to coolant three coolant feed-through pipes 218 being sprayed on by nozzle 211 on the inner wall of capstan winch 202.Capstan winch 202 inner wall has surface of revolution 203 at least on axial length " L ", is contacted with fin 204 at this.With the curved face contact Fin 204' edge by Fig. 2 a line " A " indicate.It is noted that in this embodiment, it includes capstan winch that line " A ", which is in, In the plane of rotation axis.Coolant is collected in the liquid bath 217 for being installed to work platform 214 and by coolant extractor 212 discharges.Because no longer needing sealing ring, there is no due to power loss caused by the friction of such sealing element.

In this particular example, each fin 204 is fabricated from a flexible material, by rigidly at their stake 213 It is connected to carrier.Fin is for example made of 0.8 to 1.0mm thick stainless steel plate.Alternative material is the aluminium sheet of 1.5mm.The wing Piece is at least flexure on the direction of rotation of capstan winch 219 during use.At the other edge of fin --- fin with it is interior The surface of revolution place of meeting of wall --- the angle of formation is the angle of wedge " α ", is about 15 ° in this case.Fin is pressed against capstan winch The total power of 202 inner wall is in the length of 20cm between 20 to 30 Ns.The combination of contact line pressure and the angle of wedge makes Fin skids on water coolant forward from the speed of about 100m/min.In the speed hereinafter, water coolant film breaks simultaneously And the edge " A " of fin scrapes the inner wall of capstan winch, thus removing and clean may established any deposit (such as becoming rusty).It removes This exterior piece helps to reduce the speed of capstan winch, that is, is used as additional braking.

Fig. 3 a and enlarged version Fig. 3 b show the second embodiment of the present invention.Again, cooling system is made of carrier, should Carrier is made of ring 323, is fixed in 323 upper supporting column 313 of ring, 313', 313 ".In this embodiment, fin 304,304' and 304 " are rigid.They can be made of the grey cast steel of 3mm thickness.Gray cast iron is wear-resistant well, and as grinding stone with more The surface of inner wall is cleaned well.In order to make their deflections, each fin be connected to pillar 313, wherein hinge 309 is in fin Carrier edge at.In order to by fin be pressed against capstan winch inner wall, steel knife spring part 315,315 " be installed in pillar 313,313', Between 313 " and associated fin.Here, coolant jet 311 is installed in the centre of fin and directly in the inner wall of capstan winch Upper spray coolant.

Detailed view Fig. 3 b show what has occurred when capstan winch 302 is rotating and coolant is fed.In spring Under the action of part 315 ", the angle of wedge " α " is consequently formed in the inner wall surface 303 of 304 " backup capstan winch of fin.On direction 319 just During rotation when normal service speed, fin is caused to skid on coolant together with the angle of wedge and the pressure on fin, and shape At cooling agent film 327.When winch reductor, --- or alternatively during slow rise --- film 327 is not formed, and And the edge of fin knocks the inner wall of capstan winch at touch-down zone 325.Due to the abrasion in edge, touch-down zone 325 will tightly with With the rounding of capstan winch.

Fig. 4 shows the 3rd embodiment of cooling system 401.Here, carrier is the steel pipe 413 of thickness 2.5mm, swash from it Light be cut into six fins 404,404', 404 ", 404 " ', 404 " ", 404 " " ', and then plastic bending to than in capstan winch The circumcircle of diameter bigger.By heat treatment, quenching and annealing, the yield strength of steel is greatly increased, and elasticity is consequently formed Fin.Pipe is mounted to ring 423.After being inserted into capstan winch, fin will take shape as indicated.Each fin have with The tangent touch-down zone 425 of the inner surface of capstan winch.The angle of wedge is therefore close to 0 °.Touch-down zone with(the height of Bayer Performance elastomers) it terminates.Alternatively, end is coated with grinding and wear-resistant bronze layer.Each fin is presented with from coolant The coolant that device 410 is distributed is sent to be fed by by pipe 418 that individual nozzle 411 terminates for each fin.Nozzle is twisting Coolant is sprayed between the inner surface and fin of disk.Due to angle of wedge very little, fin will be skidded forward with low-down speed (from About 20m/min), thus reduce the friction of inner wall.In order to remove deposit from inner wall, thus it must open and stop with dry type Only the machine (i.e. not supply coolant) is in order to removing deposit.

Fig. 5 shows further embodiment of the present invention according to the second aspect of the invention, that is, cooling system and capstan winch Combination.In this embodiment, the line " A " that the rotation inner surface 503 of fin 504 and capstan winch 502 is met is relative to capstan winch In the plane at the inclined angle of rotation axis " β ".The angle of inclination makes the coolant fed from nozzle 511 when capstan winch is in direction The effect of antigravity is driven upwardly when being rotated on 519.Flexible flap 504 is rigidly mounted to stake 513, their own and quilt It is installed to ring 523.Another special characteristic of the embodiment be rotation surface 503 on axial length " L " in capstan winch 502 It is recessed in wall.This is to preferably keep coolant in the place of needs.
