Description
The present invention relates to be used for the method and apparatus of molded thermoplastic circulus, relate in particular to the method and apparatus that in the coiling of thermoplasticity circulus and forming process, cleans.
In the past, most of compound circuluses are made with thermosets.When the thermosetting synthetic material was used for the production circulus, whole ring must be cured in uniform temperature in autoclave, and this temperature will be suitable for making material to reach its final solid state.In autoclave process, the fiber in the thermosets has loose and loses the trend of the arrangement in the structure.The loose of fiber is not wish occurrence, because in the prior art, well-known, the arrangement of fiber has appreciable impact to the uniformity of the strength and stiffness of composite construction.Therefore, recommended the substitute of thermoplastic as thermosets.
The technological requirement of making the thermoplastic composite of circulus is different from employed machine of thermosets and method fully.From with thermoplastic production such as obtaining many tangible advantages the structures such as cylinder ring.Particularly, when the thermoplastic composite band is added to that moment in the circulus, compacting took place and when solidifying at new band, as in the operating winding, the fiber in the thermoplastic composite matrix is fixed on compacting and when solidifying in the formed Any shape of those fibers.Fiber fixedly avoided mentioned above and the loose relevant disadvantage of fiber.Thereby, the fiber stationary arrangement in the matrices of composite material has greatly been improved the uniformity of formed composite material strength and rigidity.
Making in the field of circulus with thermoplastic composite, the major part in the work of having finished concentrates on the use convection heat transfer' heat-transfer by convection, so that the thermoplastic composite band obtains uniform temperature, when this temperature, thermoplastic composite can solidify.Convection heat transfer' heat-transfer by convection is introduced in the thermoplasticity ring forming field several years ago, to improve obtainable speed in the ring forming process.As everyone knows, in the prior art, the heat conduction of being undertaken by radiation and conduction pattern can not produce enough heat energy to the thermoplastic composite product, so that material is to solidify than 1 to 2 inch faster speed of per second.This speed refers to when forming circulus, and new thermoplastic composite band is added to the speed on the previous thermoplastic composite belt.Advection heat conduction is in the winding process of the circulus that just is being formed, and the point that begins to contact at new band and anterior layer obtains on the thermoplastic composite band by hot gas is blown to.The winding-up of hot gas makes the thermoplastic composite fusion, so new and old material is combined into one.
But the advection heat conduction is bad aspect a lot, and one of them is that efficient is extremely low.In the heat that is produced only sub-fraction be actually used in the heating thermoplastic composite material tape.The major part of the heat that produces has blown near the impulse nozzle, has heated machine, bearing, axle and other dependency structure.Another disadvantage is that convection heat transfer' heat-transfer by convection can not heat and wants certain position of heating, the novel thermoplastic composite material tape that promptly add this position and be wound on contact point between preceding one deck thermoplastic composite band on the ring.This position can not be heated, and is because the acute angle position of the gas holdup that is blown between importing band and coiling ring.The advection heat of stagnating does not have speed thereby can not conduct heat.
When with heavy wall circulus of thermoplastic composite tape wrapping, also suffer from another problem.For forming the heavy wall circulus, need a large amount of thermoplastic composite bands.This can obtain by a plurality of short relatively thermoplastic composite bands are bonded together.But the joint of introducing in the band has brought discontinuity to structure, has reduced the mechanical performance of products that forms.A replacement scheme is, the single long especially thermoplastic composite band heavy wall circulus that can be used for reeling, and it has removed the joint in the final products.The problem of this technology is to make several thousand feet long and not have the thermoplastic composite band of joint be extremely expensive.Some other loaded down with trivial details scheme is invented, but all has adverse effect, they or attempt splicing material aloft, or use a kind of curing technology that starts and stop.
The in-situ solidifying of thermoplastic composite band is a kind of effective technology that is used to make the flywheel ring structure.The general pressure roller that uses a heating of this method is used on the surface that surface with the thermoplastic composite band is pressed onto the flywheel ring to form abundant consolidated structures.A problem that occurs in this technical process is that the thermoplastic resin coating has from the thermoplastic composite band and adheres to trend on the pressure roller of heating.Optimum treatmenting temperature causes thermoplastic resin gathering fast on roller usually.This coating has caused a plurality of problems, comprising: variation, the thermoplastic composite band of the thermal conductivity from roller to ring causes the non-homogeneous pressure of product density variation and causes aggregate material the coming off at random toward product surface of variable density heterogeneous surface very greatly.
In the past, the in-situ solidifying cleaning equipment requires to stop moulding process, has the roller that resin gathers to remove, and roller is carried out manual cleaning with cleaning agent (being steel wool, sandpaper etc.).In order to remove the thermoplastic resin that is collected on the pressure roller satisfactorily, propose and carry out another prior art.This technology comprises: physical scratch-off (continuous and/or manual), passive scraper, spirality cable wire and infrared heating (local and concentrate).These technology do not have a kind of success that is proved to be.Scraper is owing to contact and heating with aggregate material with pressure roller, thereby just is being worn before the moulding process end for a long time.Scraper sclerosis or pottery causes unacceptable damage to roller surface.At last, the infra-red radiation of concentrating can not " be seen " thermoplastic resin, thereby fails resin is burnt from the roller surface.
Another shortcoming is in original curing roller cleaning technique, and as ring during by moulding, they can not be carried out continuously at cylindrical product.This is very important, because the shaping of thermoplastic composite ring can not produce any interruption, if for midway roller cleaning step technical process is stopped and starting, this interruption will take place.Continuous roller cleans to be needed, because it can be at resin and the resin vestige of just removing before the thermoplastic composite band of introducing newly contacts on solidification point on the roller.Thereby continuous cleaning helps to guarantee that pressure roller institute applied pressure is consistent on the width of the band that takes place to solidify.
Thereby, need a kind of new improved method and apparatus always, be used to use relatively cheap thermoplastic coiling circulus, it has a pressure roller that cleans continuously, and uses the heat conduction to realize the curing of thermoplastic composite.
According to the present invention, provide a kind of being used for to adopt band, preferably the thermoplastic composite band is made the method and apparatus of nearly cylindrical structural, and the method and equipment have used the roller of continuous wash.This method comprises that the axle of pivoting is to be formed for making the rotary forming surface of cylindrical structural.One or more tape wrapping on the axle forming face to form nearly cylindrical structural.In winding process, band is compacted on the profiled surface of axle by one or more pressure rollers, and this pressure roller is configured to rotate and thermoplastic is pressed onto on the profiled surface of axle.The burned device continuous wash of pressure roller is to remove pollutant and the band residue that adheres on the pressure roller.At last, belt is heated with the solidified strip material, almost meanwhile will be newly with on the skin that is pressed onto formed nearly cylindrical structural.Pressure roller solidifies band by the heat conduction.
According to other aspects of the invention, burner is a naked light burner.In order to remove pollutant and residue as well as possiblely, preferably burner has a controlled heat level.Burner fully heats pressure roller, makes pressure roller pass through heat conduction solidified strip material.By means of burner the continuous wash of pressure roller all contaminants and resinous principle have been removed from adhering to being with on the pressure roller basically.In addition, the thermoplasticity cylindrical structural uses whole automation process to produce.Owing to cancelled the interrupted needs that clean of the craft of pressure roller, thereby the continuous wash of pressure roller is allowed whole automations by means of burner.
According to other aspects of the invention, axle is pivoted and is formed for making the rotary forming surface of cylindrical structural.When axle was rotated, band was wound onto on the forming face of axle, generated cylindrical structural.Carrying material is compacted on the axle forming face by pressure roller, and this pressure roller is configured to rotate and band is pressed onto on the rotary forming surface of axle.Pressure roller burner continuous wash is removed will stick to the pollutant on the pressure roller and the resinous principle of carrying material.
In accordance with a further aspect of the present invention, pressure roller or only be heated by a burner or by the burner that combines with electrical heating.Best, burner is a naked light burner with controlled heat level.Burner fully heats pressure roller, so that roller is by heat conduction solidified strip material.The continuous wash of pressure roller being carried out by burner will adhere to all contaminants on the pressure roller basically and the resinous principle of carrying material is removed.
According to the other one side of this method, band is made of thermoplastic composite.
Summary is readily appreciated that from above, and the continuous wash of the pressure roller annular winding apparatus that constitutes according to the present invention has many benefits that are better than the method and apparatus in the prior art mentioned above.Because the present invention preferentially uses heat conduction to come compacting simultaneously and solidifies formed loop configuration, thereby the fiber that is wound in the carrying material on the axle is fixed in the arrangement, improved the mechanical performance of the structure that forms.Compacting/curing when band carries out sandwich tape at the coiling of axle profiled surface and by the pressure roller of heating makes cylindrical structural can non junction ground manufactured.At last, the use of pressure roller continuous wash makes following several respects minimum: (1) pyroconductivity from roller to ring changes, (2) cause that product density changes with on differential pressure, and (3) aggregate material coming off at random on the product surface, this coming off causes having the heterogeneous surface that greater density changes.Final result is comprehensive outstanding part quality.
When combining with Fig. 1, above-mentioned aspect of the present invention and many advantages of following will be easier to by becoming referring to following detailed understand, wherein:
Fig. 1 is the side view according to composite material ring coiler of the present invention.
Fig. 1 has described a preferred embodiment of collars coiler 10 constructed according to the invention, be used for and will one or more be with 30 to make nearly cylindrical structural 14 by what thermoplastic composite was made, it uses one or more pressure rollers 40 to conduct heat of solidification plastic composites by heat.Described collars coiler 10 comprises an axle 20 around axle 24 rotations, and it drives by a motor or other rotating power source (not shown).The excircle of axle 20 provides a rotary forming surface, uses when making cylindrical stratiform structure 14.With the rotation of axle, one or more thermoplastic composite tape wrappings are on axle.When it was reeled, the thermoplastic composite band 30 of every introducing was through almost pressure roller 40 compactings and the curing of quilt heating separately simultaneously of heat conduction.For ease of diagram, only shown a pressure roller among Fig. 1.Pressure roller is supported by a mechanical device, and this mechanical device is pressed in pressure roller on the skin that is wound on the band on the axle 20.This supporting machinery device is well known in the prior art, and schematically represents with a spring 42, and this spring is pressed against on the axle 44 that pressure roller is installed.The supporting machinery device produces a continuous pressure on the roll coil of strip outside.According to the present invention, pressure roller 40 usefulness one burner 50 carries out continuous wash, and its naked light 54 points on rollers 40 surface away from contact point, and it will adhere to pollutant on the pressure roller 40 and the resinous principle of other thermoplastic composite band 30 is removed.
The rotating shaft 24 of drive spindle 20 preferably is positioned at horizontal plane substantially.This direction of rotation is preferred, because thermoplastic composite band 30 is heated to a solidification temperature by pressure roller 40, thereby makes the interior resin of thermoplastic composite band be in the semi-molten state of thickness.If the rotating shaft 24 of drive spindle 20 is positioned in the vertical substantially face, the molten resin of thickness can form the final products of deformity because the trend that flows vertically of gravity effect and oriented formed cylindrical structural bottom.
Again referring to Fig. 1, the thermoplastic composite band 30 of introducing is preferably supplied with by a material feed spool (do not show but known in the prior art).In addition, in normal compacting and solidification process, it is favourable being in tension when arriving pressure roller 40 with 30.Tension force has reduced the defective on the final products, such as wrinkling and other extrusion defect.Be the input thermoplastic composite band 30 that generation is tightened, preferably use the roller that pulls up (do not show but be known in the art).After band leaves feed spool and before being with 30 arrival pressure rollers 40, the roller that pulls up will be with 30 to be limited on a bit.A kind of well-known frictional limited technology is included in a pair of juxtaposed guiding thermoplastic composite band 30 between the roller that pulls up.
Thermoplastic composite band 30 heated pressure rollers 40 press against on the forming face of axle 20, this as shown in Figure 1 with above-mentioned discussion like that, pressure roller 40 is arranged to rotate and thermoplastic composite band 30 is pressed against on the nearly cylindrical structural 14 that forms in axle 20 surfaces.Thermoplastic composite band 30 contacts the heat conduction that causes by the pressure roller 40 with heating and is heated to uniform temperature (glass transition temperature that is higher than material), this temperature is enough to solidify to form the thermoplastic composite with 30, almost meanwhile, compacting and the thermoplastic composite band of introducing 30 added in the cylindrical stratiform structure 14 of shaping.
Though the moulding that relates to the nearly cylindrical structural of being made by thermoplastic composite band 30 14 that the present invention mainly discusses, the present invention also can be used to produce the structure of using other types of material.For example, the thermosets compaction process also can use the burner 50 of band naked light 54 to remove residue and/or the pollutant on the pressure roller 40.More clearly, according to the present invention, adopt the compaction process of metal, alloy, mixture or other compound of pressure roller also can remove residue and pollutant on the pressure roller 40 with burner 50.
As shown in Figure 1, roller 40 is expressed to the thermoplastic composite band of introducing 30 on the nearly cylindrical structural 14, and this structure 14 forms by introducing to be with on the circumference forming face that presses against idler spindle 20.As previously mentioned, pressure roller 40 is heated, but this roller by and with the heat transfer contact between 30 with 30 heating of thermoplastic composite band.This heat be enough to almost with will introduce band and be compacted on the periphery of the structure that forms in, the resin during curing is with.The previous heating pressure roller that uses uses the mechanism such as the internal electrical coil to produce necessary solidification temperature (usually above the glass transition temperature of thermoplastic resin).As mentioned above, according to the present invention, preferably burner 50 fully heats pressure roller 40 to eliminate the demand to additional heating arrangements in the continuous wash cyclic process.So, the present invention has reduced the cost and the complexity of equipment 10, has improved the efficient of production method simultaneously.Internal electrical coil or other heating mechanism (figure is schematically shown by coil 58) that the alternative embodiment of the present invention material with high solidification temperature of specific type (or be used for) can adopt the heating to pressure roller that produces with burner 50 to combine.Electric coil can be used to preheating pressure roller when starting.Even in these embodiments, burner 50 provides some heating pressure rollers to the suitable required heat of temperature at least.Therefore, even in these embodiments, the present invention has reduced required energy and has saved cost considerably.
In another alternative embodiment of the present invention, pressure roller 40 is mainly used in (or only being used for) thermoplastic composite band 30 is depressed into the periphery of the cylindrical structural 14 that has been shaped, and is not used in by the heat conduction and is cured.In these embodiment of the present invention, used other method that thermoplastic composite band 30 is heated to solidification temperature (such as convection current, infrared heating etc.).Because pressure roller 40 still is subject to the covering from resin or other residue and other pollutant of thermoplastic composite band 30, these embodiment have used the burner 50 among the present invention, to provide pressure roller required continuous wash.Thereby the continuous wash by 50 pairs of pressure rollers 40 of burner of the present invention is effective and useful, and no matter which kind of heat-transferring method what thermoplastic composite band 30 was heated to that solidification temperature uses is.
Burner 50 constructed according to the invention is preferably in before roller 40 has an opportunity to change a whole circle and pollutant and resinous principle are expressed on the new forming face of nearly cylindrical structural 14 of manufacturing, preferentially will adhere to whole thermoplastics and other contaminant removal on the pressure roller 40.Preferably, burner 50 uses naked light.And preferably, the rank of the heat of burner generation or naked light 54 or speed can be by suitable controller 60 controls.Residue and other pollutant that the control of burner 50 allows burner temperature rank and firing rate to be configured to reach different kind of material are removed required rank fully.Thereby the present invention allows to obtain required naked light 54 and heat level by burner 50, obtains the cost benefit under low level heat or the acceptable situation of naked light simultaneously.
Another advantage is that the annular roll device 10 of formed continuous wash pressure roller allows the moulding full automation of nearly cylindrical structural 14 according to the present invention.By cancelling the pollutant that is used to strike off on the pressure roller 40 and the full-time worker of residue, the invention provides than manual and strike off more excellent further cost savings.
The present invention is described at method for optimizing and preferred equipment.After having read aforementioned specification, those of ordinary skill can be made other different variations, change and be substituted or other corresponding modify under the situation that does not depart from disclosed viewpoint.Thereby should know that within the scope of the appended claims the present invention also can be implemented except that specifying herein.
