Description
Technical field
The utility model relates to a kind of lamination device for being manufactured three-dimensional prefab by fibrous material.
Background technology
At fiber composite component, be also referred to as in the manufacture of fibre-inforced plastic parts, the existing conventional method of the one for commercial Application is such as so-called RTM method (resin transfer moulding).The manufacturing process be made up of multiple independent process adopted in this case finally obtains the plastic components preparing to use.First, the prefabricated component close to final profile or fibre semi-finished products is produced.Be also referred to as prefabricated component these parts usually by multiple independent tissue layer or fiber mat, usually in a two-dimensional manner in so-called precasting process such as by bail, gluing or by the known method of textile technology, such as to sew up etc. and be stacked and/or link.The thus obtained stacking material be made up of independent tissue layer or fiber mat has desired exterior contour in this case substantially, and typically can also have the special characteristic of thickness, specific fiber ranks etc.Generally speaking, after manufacturing stacking material by tissue layer, before they are further processed to form fabric or fiber mat, adhesive is applied to tissue layer, or such as because independent fibre bundle is impregnated with such adhesive Already between fiber.
Subsequently, the stacking material of tissue layer carries out pre-molded usually in lamination device, this lamination device depicts the 3D shape of the expectation of the prefabricated component in mould, usually by being implemented as interactional one or more laminating and/or fixed punch casting die with mould, fabric stacking material is squeezed in mould, thus realizes desired 3D shape thus.Adhesive such as can be activated by the heating of mould subsequently, and cooling die thus make the profile of three-dimensional prefab close to final profile subsequently, and at least can by the preparation process of operation for other.Lamination device is known substantially, such as, be disclosed in DE 10 2,010 027 466 A1 or DE 10 2,010 043 666 A1.For three-dimensional prefab quality determine be, the independent layer of described stacking material is like this as far as possible against in a mold, that is, there are not fold, less desirable strain, less desirable tension force etc., thus the three-dimensional prefab of first water can be obtained thus, wherein stacking material is uniform.
In mentioned document, therefore lamination device is rotated, such as make laminating and/or fixed punch casting die be squeezed in mould from below by fabric stacking material, thus gravity auxiliary under realize the lateral tension of fibrous material, thus easily can avoid folding and fold.But this is associated with high cost, because on the one hand, mould and structure must correspondingly rotate, thus make stamping parts to be sufficiently elevated.In document mentioned by other, be provided with alignment pin, which ensure that at mould and effect similar with it when extremely pushing up position need not be rotated in a complex manner.But in this case, the manufacture of mould is especially complicated, because described pin must implement possibility plane the most accurately at their extended position, and because all pins must be retracted in mould.Described mould becomes very complicated parts therefrom, thus the cost caused by this mode is only worth for very large series, and disadvantageously, it does not allow the flexibility of mould.In addition, this very complicated mould is easy to fault especially in the manufacture process of prefabricated component.
After manufacture three-dimensional prefab, its intermediate close to final profile as pre-molded and be laid in press, to perform RTM method.Three-dimensional prefab also can be trimmed before, carries out punching press, or be provided with insert etc. as required in precalculated position, thus realizes the most accurate as far as possible profile and the function of fibre-inforced plastic parts subsequently.After three-dimensional prefab is placed in instrument, closure tool half can be carried out in a way known subsequently, and desired resin is injected in the die cavity of instrument, thus floods the fibre structure of three-dimensional prefab and surround fiber.After resin matrix solidification, the fibre-inforced plastic parts obtained thus, can remove this parts from this instrument.
Because in the process manufacturing such fibre-inforced plastic parts, important step has been arranged in the manufacture of three-dimensional prefab, the lamination device used for the quality of back part there is decisive meaning.According to the lamination device of prior art, there is mentioned defect in this case as above.
Utility model content
Target of the present utility model is the lamination device proposing to improve, and it avoids these shortcomings especially.This target is realized by the lamination device with following technical characteristic according to the utility model, that is, a kind of lamination device, and this lamination device is used for producing three-dimensional prefab by fibrous material, and has: mould, and described mould reflects the 3D shape of prefabricated component; For laminating and/or fixing one or more stamping parts, described stamping parts and mould interact; Wherein, different stamping parts has different surface roughnesses and/or coefficient of friction on its first surface towards prefabricated component and/or in the zones of different of the first surface of at least one stamping parts; And/or the second surface towards prefabricated component of mould has surface roughness and/or the different region of coefficient of friction.
According in lamination device of the present utility model, laminating and/or fixed punch casting die has different surface roughnesses and/or coefficient of friction on their surfaces towards prefabricated component and/or in the zones of different on the surface of and/or fixed punch casting die laminating at least one.Additionally or alternatively, mould also can have such region on its surface towards prefabricated component, these regions have different surface roughnesses and/or different coefficient of frictions.According in lamination device of the present utility model, can be implemented as there is different surface roughnesses or coefficient of friction by the different stamping parts of regulation thus, if or identical stamping parts, particularly described stamping parts have on its surface towards prefabricated component corresponding complicated shape, there is different surface roughnesses and/or coefficient of friction.Alternatively or preferably additionally, mould also can be implemented as has different regions, thus makes it have different surface roughnesses or coefficient of friction.Surface roughness can be detected with metering method in this case, such as by peak to the paddy degree of depth, particularly in the mode of average peak to the paddy degree of depth, and can to manufacture according to desired numerical value.
By the change of such surface roughness and/or coefficient of friction, just can realize fibrous material, be namely made up of tissue layer, the different sliding properties of the stacking material that is provided with corresponding adhesive alternatively.Because be arranged on the stamping parts in mold center, each several part of stamping parts or die surface there is the surface of respective smoothed or be coated with the material, the such as polytetrafluoroethylene (PTFE) that reduce friction, so fiber extraordinary slip on the stamping parts of correspondence just can be realized in this region, thus fiber just can be squeezed in the reverse of mould by stamping parts easily that be usually embodied as laminating stamping parts in low friction.For fibrous material, other stamping parts or other region of mould or stamping parts can be provided with the surface with higher surface roughness and/or more great friction coefficient accordingly, what such as have mechanical rib etc. is not intended to coarse surface, or by being correspondingly coated with such as polyurethane, polyurethane such as causes fibrous material to produce the coefficient of friction more much higher than the polytetrafluoroethylene (PTFE) mentioned.
Because the region of these stamping parts or stamping parts or die surface are preferably arranged in the exterior lateral area of mould, so it is ensured that compared to having surface more level and smooth accordingly or having the stamping parts or surface that are implemented as less surface rubbed, the material of prefabricated component can be held more securely.The region that this material can have the stamping parts of larger surface roughness or higher coefficient of friction from employing subsequently, draw in mould by other stamping parts.By this way, achieve very agile contact, and fold etc. can not occur.In this case, the structure that structural rate describes in the prior art, the structure such as with alignment pin are simply too much, because only need process the correspondence surface of laminating and/or fixed punch casting die and/or process the surface of mould alternatively, to realize desired effect.Different surface characteristic about surface roughness and/or coefficient of friction can realize simply by the process differentiation made between each several part surperficial or surperficial separately in this case very much.
According in the very favorable form of lamination device of the present utility model, at least one that also can specify in laminating and/or fixed punch casting die provides elastically deformable layer at least in part on its surface towards prefabricated component, or is made up of the material of elastically deformable.This elastically deformable layer can be elastomer layer etc., it such as covers the surface of laminating stamping parts, or it is particularly inserted in grinding flute accurate adaptation, thus to make it realize relative to all the other regions on the surface of laminating stamping parts be in a deformed state the surface of level.In laminating process, after the contact of laminating stamping parts on fabric stacking material has been implemented, utilize the elasticity of deformable material can perform further forward travel.By this way, the further motion of the stacking material be made up of tissue layer can be performed, thus such as tensioning material and/or each folding line of flattening.
According to the favourable mode according to the utility model lamination device, at least one that can specify in laminating and/or fixed punch casting die and/or mould is being applied at least in part on the surface of prefabricated component.Surface characteristic can by coating at least part of like this and easily changing, such as, partly applied in target area subsequently by machining equably by surface.Described coating such as can be implemented to and friction and/or surface roughness are lowered, otherwise or, such as, by being applied with the layer of polyurethane of local, coating can be implemented in each site, thus friction or surface roughness are enhanced.
According in the very favorable embodiment of the another kind of lamination device of the present utility model, also specify that at least one surface towards prefabricated component that is laminating and/or fixed punch casting die has different coatings.The zones of different on the surface of single stamping parts can be adjusted to desired different qualities thus easily, such as because each several part on surface is implemented the coating reducing friction, such as based on PTFE, and the other parts on surface are implemented the coating increasing friction, such as, based on polyurethane.In principle, also can remain with uncoated surf zone between, the characteristic of the surf zone of these uncoateds will between the characteristic of two kinds of coating zones.
But, for manufacturing independent laminating and/or fixed punch casting die, in order to minimize cost, also can specify according in the particularly advantageous form of lamination device of the present utility model, there is provided and there is the multiple laminating of different surfaces and/or fixed punch casting die, each surface towards prefabricated component that is laminating and/or fixed punch casting die is all implemented substantially consistent surface roughness and/or coefficient of friction equably, is wherein provided with and has the multiple laminating of various surface and/or fixed punch casting die.Each stamping parts itself be implemented as this structure with uniform outer surface for stamping parts manufacture be simple especially because surface can be processed equably when there is not mask etc. and/or be applied.Because multiple stamping parts can be used in lamination device now, desired characteristic still can be implemented, and such as, stamping parts owing to being positioned at more lateral has more coarse surface or higher coefficient of friction than the stamping parts being arranged on central authorities.By this way, the fibrous material of prefabricated component is subsequently maintained in the fringe region of mould accordingly, and must be extruded by the larger frictional force had in the region of the laminating stamping parts of the corresponding more inside of low-friction surface, the outside stamping parts of opposing and be pulled in mould.Therefore, very clear agile prefabricated component can be produced, and do not have the obvious risk of fold etc.
According in the particularly advantageous form of lamination device of the present utility model, specify extraly now, at least one in laminating and/or fixed punch casting die has the direction of motion relative to the die surface corresponding with it, the vertical line that this direction of motion departs from the vertical line on the die surface corresponding with it or divides equally in the plane on this surface.In laminating and/or fixed punch casting die at least one thus relative to vertical line obliquely, preferably with the angle being greater than 5 ° towards each the independent fiber in the stacking material of the structure tensioning fabric layer alternatively of mold movement.The motion of this inclination, be particularly combined in the feed-in process of stamping parts with the elastically deformable surface of stamping parts and produce fiber or fibrolaminar transverse movement respectively on the face of the die, folding line is made to be flattened thus, and alternatively or additionally, realize redirecting of fiber alternatively.This is particularly combined with deformable material as above and is suitable for, this is because transverse movement particularly so subsequently can be realized by remaining stroke in the fixing fibrous material of the stacking material of tissue layer, this remaining stroke is by utilizing elasticity to realize.
Other favourable embodiment according to lamination device of the present utility model is obtained by remaining dependent claims, and becomes apparent based on exemplary embodiment, and it will hereafter be further described in more detail by reference to the accompanying drawings.

Detailed description of the invention
In the explanation of Fig. 1, schematically show commercial plant 1, this commercial plant is finally for manufacturing fiber reinforcement moulding part 2 in the instrument 3 of the mode by RTM method in press 4.Fortifying fibre moulding part 2 is manufactured by prefabricated component 5 in this case, and it is be similar to final three-D profile by pre-molded, and it is manufactured in advance in shown several illustrated steps.Fibrous material such as in the form such as tissue layer, fiber mat is used as the initial substrate of prefabricated component 5.Fibrous material such as can be provided as coiled material by shown volume 6.
In cutter sweep 7, the independent tissue layer be not here clearly shown or pad cut into certain size by cutter unit 8 by coiled material subsequently.Subsequently, this tissue layer is supplied to by suitable conveying device (it is only schematically indicated by bending arrow in the explanation of Fig. 1) and indicates unit 9, and in this unit, adhesive is applied to tissue layer.This such as can be implemented by spraying, roll-in, impregnating.As the replacement using unit 9 to apply this step of adhesive, fibrous material pre-preg also can be made to have corresponding adhesive, thus this step can be saved.But this is prior art routine to those skilled in the art, thus makes it not need to be discussed in further detail here.
After being applied with adhesive, if or this step is removed and adhesive Already in fibrous material, tissue layer can arrive stackable unit 10 subsequently immediately, and tissue layer independent in this stackable unit is stacked to be formed in the stacking material 11 that shown here is made up of tissue layer.In this case, for design reason for reasonably and be the position needed also can provide bail, stitching or fabric layers other connect.Carry out cutting operation in cutter sweep 7 after, tissue layer has the shape being similar to final profile usually.But, in stacking tissue layer with after form stacking material 11 in stackable unit 10, if need or expect, can cut out further, go out opening etc.
After preparing stacking material 11 thus, in shown exemplary embodiment, stacking material enters heating unit 12, and in this heating unit, stacking material is guided through heating furnace by conveying mechanism, is had the part etc. of infra-red radiation as shown.Stacking material 11 is preheated, and is generally and can is sufficiently activated by the adhesive of thermal activation or is fully liquefied, and to make stacking material 11 still have high flexibility, but tissue layer treated in stacking material 11 bonds mutually when cooling.
The Core Feature manufacturing the prefabricated component 5 of three-dimensional pre-molded is designed to lamination device 13 shown in a subsequent step.Lamination device 13 has mould 14 in this case, and the shape of the preformed prefabricated component 5 of three-dimensional subsequently described by this mould.The stacking material 11 be made up of tissue layer is by being extruded in the model of mould 14 for laminating and/or fixing stamping parts 15, and usually cooled by the metal material of mould 14, this metal material has very good thermal conductivity and to leave heat from the stacking material 11 of tissue layer.In this fashion, adhesive solidifies, and obtains the prefabricated component 5 of three-dimensional pre-molded, and this prefabricated component has been molded as the shape being similar to final profile, and consistent with the shape of mould 14 and stamping parts 15.Can adopt the stamping parts 15 of anchoring fiber material, and/or particularly stamping parts 15 such as can be used as laminating stamping parts, it is for such as moving in the groove of mould 14 by fibrous material.
The size of prefabricated component 5 is fully stable due to the adhesive of solidification in this case, can not lose its shape, and prefabricated component at least can be carried and optionally temporarily stored further.But prefabricated component not yet reaches its net shape and hardness, this just realizes in RTM process subsequently.As above, within it to be glued together ideally and the stacking material 11 solidified forms prefabricated component 5 subsequently by pre-molded in lamination device 13 thus, prefabricated component can be supplied to the press 4 for RTM method.
Especially, designed by particular importance now for the laminating stamping parts 15 drawing in the stacking material 11 be made up of tissue layer, because the very uniform tractive that must perform in the groove of stacking material 11 to the mould 14 be made up of tissue layer or extruding.Only just can avoid the folding line in the material of stacking material 11 or unnecessary tension force thus.But this is for the demand of property based on the good quality of the moulding part 2 manufactured in RTM method, and associated, produces good quality thus when fiber reinforcement moulding part 2.In order to realize the stacking material 11 of tissue layer, be namely finally that fibrous material is pressed into or draws in mould 14 or its groove in high quality, can specify in lamination device 13, independent laminating and/or fixed punch casting die has different surface roughnesses and/or coefficient of friction at them on prefabricated component 5 subsequently or the surface of stacking material 11 that is made up of tissue layer, described first surface in the diagram of Fig. 2 respectively with 16 marks.In this case, each independent stamping parts 15 all has such region on its first surface 16 in principle, and this region has surface roughnesses different wittingly or coefficient of friction.But the first surface 16 of stamping parts 15 itself is desirably substantially uniform, and different stamping parts 15 has different surface roughnesses or coefficient of friction.
Especially, when with reference to figure 2 be reasonably, two the less stamping parts 15 being arranged on outside have higher surface roughness or higher coefficient of friction on their first surface 16, thus hold thus and the material of stacking material 11 that is made up of tissue layer of tensioning.Accordingly, the surface with larger surface roughness or more great friction coefficient is identified as 16*.Central authorities stamping parts 15 respectively by the material of stacking material 11 extruding or tractive in the groove of mould 14.Central authorities' stacking material 15 has correspondingly good surface quality in this case, has low-down mantle friction degree or low-down coefficient of friction respectively, thus material is slided thereon especially well.This first surface is identified as 16 ', and it such as can be polished.Substantially alternatively, but particularly additionally, mould 14 the material towards stacking material 11 and the second surface being designated 17 in fig. 2 also can have such region, the coefficient of friction of the vicissitudinous surface roughness of this region tool and/or change.The material tractive of stacking material 11 is therefore also correspondingly easier to groove, if such as edge and radius must flow around the material of stacking material 11, by correspondingly polishing, and such as, mould 14 be also coarse with two interactional second surfaces of outside stamping parts 15 17, thus hold the material of (suppression) or tensioning stacking material 11 time in it is by central stacking material 15 tractive to the groove of mould 14.
Accordingly in this case, surface roughness or coefficient of friction must be adapted to used fibrous material respectively, such as, be carbon fiber in fibre reinforced moulding part 2.In order to manufacture correspondingly large surface roughness or great friction coefficient, process by such execution, such as, rib-like structure that is that surface has microcosmic or that can also be macroscopic view, thus realize the bonding on fiber and the first and second surfaces 16,17 thus.Thus, fibrous material is held, and can be tensioned by central stamping parts 15 accordingly.By this way, edge, folding line or fold in stacking material 11 material can be considerably reduced.When described outside stamping parts 15, in often kind of situation described by Fig. 2, such coating must to produce the fiber relative to fibrous material such as than central stamping parts 15 surface or put on the higher coefficient of friction of its coating.Feasible coating will be arranged in the region of outside stamping parts 15, and to produce higher coefficient of friction, coating is such as made up of polyurethane, and it has relatively high coefficient of friction for fiber.Central authorities' stamping parts 15 can have the coating reducing coefficient of friction, such as, accordingly based on polytetrafluoroethylene (PTFE).
Therefore, the use with the first and second surfaces 16,17 of different surface roughnesses and/or coefficient of friction allows the material of stacking material 11 between the second surface 17 of mould 14 and the first surface 16 of the stamping parts 15 of correspondence pointedly " flowing ", thus fibrous material very accurately can be performed by the suitable coating on the first and second surfaces 16,17 or processing to uniform in the groove of mould 14 and the tractive that do not contain fold.
This especially good draw in of material between the second surface 17 of mould 14 and the first surface 16 of the stamping parts 15 of correspondence of stacking material 11 can be assisted now further, because first surface 16 is provided with at least one stamping parts 15 with elastically deformable layer, or whole stamping parts 15 is implemented by the material of elastically deformable.Such as, deformably resilient material can be inserted in the grinding flute in the stamping parts 15 that is made up of metal or plastics, makes especially in deformation state, has the level surface realizing stamping parts 15 between the region of elastomeric material and region adjacent with it.Such as, when using rubber or rubber like material, the surperficial 16* with higher coefficient of friction is side by side realized subsequently.Due to deformable material, after the feed motion of reality, and if if further tensioning if required material 11 flatten and also if required to being arranged in fiber pre-tensioner of material or redirecting and can utilize electric power, realized by the remaining stroke of stamping parts 15.
In the figure 3 representation, the replacement embodiment of lamination device 13 can be seen.Independent stamping parts 15 no longer all moves perpendicular to the corresponding second surface 17 of distributed mould 14, but partly tilt (paired linea angulata) with the vertical line S in the respective surfaces 17 of mould 14, if or it is uneven words, then tilt with the vertical line S of its centre plane.In specifically exemplary embodiment in the figure 3 representation, the central stamping parts 15 with corresponding smooth surface 16 ' can the time particularly first move along the direction of mould 14 subsequently.Subsequently, adjacent stamping parts 15 can move, and these stamping parts are outwards fed to obliquely, and particularly has more coarse first surface 16*, and therefore causes the outside tensioning of the material of stacking material 11.Subsequently, outside stamping parts 15 can be fed into, and it also has surperficial 16*, has higher surface roughness in the illustrative embodiments that described first surface 16* is shown here.
If two now particularly adjacent with central stamping parts 15 stamping parts 15-except their first surface 16* would be for the material fibrous material except larger roughness or higher coefficient of friction-be also provided with as mentioned above with such as elastically deformable, then by after the actual feeding of remaining stroke that can be realized by electric power, the transverse movement that the material of stacking material 11 is outside in the embodiments of figure 3 will realize, thus make easily to remove folding line, and if the tensioning of fiber if required, can be realized or redirect.If in this case, the second surface 17 of mould 14 and the first surface 16 ' of central stacking material 15 are correspondingly embodied as level and smooth, and so material just easily can flow along it, thus guarantee the desired contact on the second surface 17 of mould 14 thus.This is also applicable for two stamping parts 15 outside being arranged on.By this structure, each stamping parts 15 one after the other, is particularly placed from inner side to the outside ground time with staggering alternatively, and lamination device 13 thus can by further optimization again.
To those skilled in the art it is known that stamping parts 15 has driver 18, actuator can make stamping parts move upward in the side towards or away from mould 14.According to arrangement and the laminating geometric configuration of driver 18, stacking material 11 therefore also can be realized in die surface or be parallel to the corresponding sports of die surface in laminating process.
