Abstract
The present invention relates to a forming component. The surface of the forming component is provided with a covering. The forming component is especially used for manufacturing the surface layer of the interior of each motor vehicle. The forming component is provided with a lining board. Firstly, the lining board is heated under the undeformed condition. Then, the lining board is inserted into a die pressing assembly with a temperature regulation function. In the die pressing assembly, one layer of covering material is arranged in the position of the lining board facing the final visible surface, and the covering material and the lining board are fixed together when the lining board is deformed or formed.
Description
This be one about making the method invention that the surface has obducent shaped component, it is particularly useful for the superficial layer of maker motor-car content.Above-mentioned member has a liner plate, does not heat under the deformation state at it, send into then in the die module of a temperature adjustment, in this assembly, surface coating material be fixed between the liner plate deformation phases liner plate on one side of final visible surface.
Said method comes from practice widely, and liner plate and cladding material are delivered to die module or builder together, and they are processed to one therein.For reaching this purpose, make-up machine can cool off or be adjusted to suitable temperature.
Existing processing method has its advantage on the viewpoint of economy, processes such as it can form by a shirtsleeve operation, fixing or even side cut.
But existing method also has shortcoming, and the whole surface of liner plate only can cover one, and is same material.
The method of practical application now is different with our invention, it is earlier the moulding and be cut into the size of needs in the make-up machine assembly of heating of cold lining material, and then on the preformed liner plate of said method, spray one deck glue, in another make-up machine assembly, cladding material is fixed on the liner plate.This a kind of like this possibility just occurs, if promptly two kinds of different cladding materials are covered the zones of different on liner plate surface, just need carry out twice operation by said sequence.
After covering shaped component as stated above, also need further to work, i.e. excision or the fixedly edge that stretches out of cladding material, and for the situation that on a formation of lots member, covers two different materials, on the seam between two different surfaces zones, also to stick cover fillet.
The shortcoming of existing this method is: it need take repeatedly procedure of processing, and considers from economic aspect, and this needs to be avoided just.By DRP prospectus DE-OS3109338, we know to also have a kind of similar method, promptly the section of two different materials is fixed on the preformed liner plate simultaneously, rather than carry out one by one as described above.For reaching this purpose, earlier section being installed in one compresses on the support, then this support is inserted in the independent junctor assembly, on the line of two sections hold down gag is housed, thereby make section fixing in position, heating section then, the air of the patrix of finding time upwards sucks in the patrix of mulch-laying machine assembly section.
For cladding material and the preformed liner plate that has inserted make-up machine are fixed together, patrix and compress support and descend together is placed on the counterdie patrix, and at this moment, hold down gag and liner plate surface come in contact.
It is to adopt following method that cladding material produces tight the contact with liner plate: lead to air at the upper space of cladding material, thereby vacuum state disappears; Air in the cladding material lower room is extracted out by liner plate, sticked together thereby cladding material and liner plate are closely inhaled.
This existing method is suitable trouble, because it also comprises repeatedly independent operation, particularly when the upper and lower mould parts of make-up machine assembly vacuumize, has not only changed money especially, but also has needed the make-up machine assembly to have special structure.In addition, the liner plate that this existing method only can be used to breathe freely, otherwise, in corresponding covering process, just can not suck cladding material on liner plate; Simultaneously, cladding material must be a gas impermeable material, otherwise the upper die and lower die of make-up machine assembly just alternately vacuumize and have not been worth.
The purpose of this invention is to provide a kind ofly, adopt the method on a formation of lots member,, in two zones on its surface, to cover different materials at least in simple and economic mode as determined method in the foreword.
The present invention takes following method to reach this purpose, and with two or be pressed in the die module more than the form of two sections, these sections will cover the zones of different of liner plate surface coating material; Before covering the section distortion,, liner plate is contacted at liner plate with repeatedly seam, seam or the line generation pressure of the section that compresses along section by means of the downward effect of making progress of clamping device.
Only comprise a spot of operating procedure according to method of the present invention, so it can be under the prerequisite of saving cost effectively, provide different cladding materials is fixed to possibility on the liner plate different surfaces zone.
At first, we notice, in the method for the invention, shaped component is in a shirtsleeve operation, and existing shape has been finished covering process again; Simultaneously, with in once operating, can also repair the edge of shaped component at this.
Cover different materials and finish with a kind of beyond thought mode on liner plate, it does not consider to cancel the facility of bleeding of the forming machine assembly that uses in the prior art.The special benefits of this method is: when enforcement is of the present invention, and be not limited to use ventilative lining material and air-locked cladding material, therefore, for purposes of the invention, the range of choice of Applied Materials is much correspondingly extensive.
Clamping device is a simply and effectively device, and it can be placed in cladding material on the liner plate and clamp join domain, thereby guarantees can aim at fully mutually in the forming step of back.Different with prior art, use method provided by the present invention, when section was clamped on the common plane, liner plate and section came in contact, and so just can be placed on liner plate with respect to the appropriate location of cutting into slices along the line between the section.On this point, it is very important that liner plate also was not out of shape when this step, and the distortion of liner plate makes the upper and lower mould of make-up machine relatively move afterwards and produces.This is just to carry out after mutual alignment between cladding material is determined fully with regard to the moulding that means liner plate.Therefore, the Position Control of line between the cladding material section is depended in the distortion of liner plate in some way.The result who does like this, the line between the cladding material section always suitably is positioned on the liner plate, and can not resemble usually take place in the prior art secundly.Even these existing methods have adopted preformed liner plate, can not avoid this skew.
Because the formation of accurate positioning and line, can avoid using cover fillet no matter whether the present invention just can use under the situation of Different Covering Material.
According to an advantage of the present invention, liner plate can be fixed in the section along the line of section before distortion, and therefore, section can not only be placed on the appropriate location of liner plate, and can also be fixed on the optimum position of liner plate.
According to another advantage of the present invention, the section of braided material can be supplied with die module with its tension.Here the explanation of broad sense should be made in " section " this term, and it comprises any material that should do the surface covering, no matter whether it is the genuine sliced form with limited surface zone, still the boundless form of fabric that has no chance all should be interpreted as section.If use the material of form of fabric, should note appropriate its edge of cutting out and repair, to form overlapping line or seam, just connecting line.
Under tensioning state, provide braided material to be applicable to roll release formula (off-the-roll) production method, and can reduce cost.
Also can derive the device of making that class shaped component discussed above by the present invention.This apparatus features is: each upper die and lower die parts all has a clamping device, in order to clamp the slice surface cladding material of making more than two or two.Above-mentioned clamping device is installed on the mutually relative position, stretches (referring to Fig. 1) at their clamped position from corresponding stamper component, and can overcome impedor resistance and insert in the corresponding stamper component.
Before the distortion beginning, clamping device stretches out from corresponding stamper component, and it can locate the cladding material that compresses and be fixed on the liner plate effectively before the section distortion at liner plate.In the process of distortion, clamping device can overcome resistance (that is power of spring) and back into corresponding pressure and release in the parts, thus moving when not hindering distortion.This resistance can be selected like this, promptly before stamper component is approaching mutually, has just added their needed power of pressing between section and the liner plate.On the other hand, also can hank resistance like that, promptly only in deformation process, just add needed power by the such method of the pressure stroke of quadrant system clamping device.Certainly, it also is feasible taking the next reinforcing of intermediateness between the two.
From being simplified to the viewpoint of type mechanism, upper mould part is equipped with pressed component, by them section is compressed in one plane, and the determined plane of clamped position when clamping device is stretched out fully just on this plane is done more favourable like this.
Now, we describe several embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 represents to make the cutaway view that the surface has obducent formed parts device, and it comprises the upper die and lower die parts that are in open mode.

Fig. 8 represents the vertical view of the summary of another kind of embodiment constructed in accordance, and wherein cladding material is that form with two fabrics that separate provides.
Fig. 9 represents a plan view from above of lining member, on this lining member, has two places to have ornament.
Figure 10 represents the cutaway view that shaped component shown in Figure 9 cuts along X-X line.
Device shown in the figure all can be used as the manufacturing surface and has obducent shaped component 1, is particularly useful for making the door lining member to that class interior of motor vehicles shown in Figure 5 as Fig. 2.Each this class A of geometric unitA all has a liner plate 2, and in the present circumstance, it is made by the propylene that is filled with wood sawdust.The cladding material 3 that can see when being covered with final the use on the liner plate 2.For the present invention, corresponding surface is a line by seam or overlap joint line 4() be divided into two or more than two isolated area.On liner plate shown in Figure 22, two such zones 5 and 6 are only arranged, the section of the cladding material in these two zones is respectively 7 and 8.Every section covers whole shaped component on the length direction of shaped component, but only accounts for the liner plate width half greatly at width.Section 8 is overlapped in the section 7 along its connecting line 4.Process U-lag 9 on the liner plate 2, the direction of groove is consistent with line 4.
For section 7 and 8 different material behavior are described, section 7 usefulness chain-dotted lines represent that section 8 dots in Fig. 3.
The surface of shaped component shown in Figure 4 is divided into three zones, if consider to provide arbitrarily additional Connection Element, what for to covering with different cladding materials in 4 zones.These surf zones are equally also separated from each other with line, represent cladding material difference organizationally with different patterns among the figure.A main connecting line 4 and two branch lines 4 and 10 are arranged in this formation of lots member, divide the angle of line and main line approximately to be respectively 60 and spend.
In the embodiment shown in fig. 5, shaped component 1 has two surf zones that separate, and this is with shown in Figure 2 the same, but in the member shown in this figure, the part of the line 4 in two zones is curves.
Fig. 1 represents to make according to the present invention the cutaway view of surface coverage formed parts 1 device.This device has a vertically moving upper mould part 11, be equipped with actionless lower mould part 12, in illustrated embodiment, have a shaping recess on the upper mould part, its shape is corresponding with the moulding projection on the lower mould part.The position of the line 4 on the member that will be shaped and cover is equipped with elongated clamping device 13 and 14 respectively in the upper and lower mould parts 11 and 12.The resistance that these clamping devices can overcome spring 24 inserts in the corresponding die module.The clamping area of clamping device is consistent with the surface configuration of connecting line.
Being fixed on general tightening member (as screw 15) on the patrix is a hold-down frame 16, by it the section 7 and 8 of tensioning state is pressed on the device.
This hold-down frame has one than the bigger outstanding surface region of formed parts 1, and surrounds upper mould part 11 from four limits.Section tensioning on the direction of connecting line 4 is vital, only in this way, just can make section obtain accurate in locating.Certainly, as long as guarantee not influence the adjustment connecting line, section also can be in the lateral tension of connecting line 4.
As shown in Figure 1, section 7 and 8 generally is pressed under certain force of strain in the public plane E, is approximately 5 millimeters along the overlapping width each other of line direction.In the embodiment shown in fig. 1, clamping plane E flushes with the plane of upper mould part 11 basically.
Elongated clamping device 14 on the lower mould part 12 just in time is contained in the opposite of clamping device 13, just can apply a suitable clamping force like this between their clamping area, the size of power is determined that by the spring size that is attached thereto the position that clamping device also can be designed to as shown in Figure 1 like that only is pressed onto section on the liner plate; Perhaps, if each in addition part adopted someway as high-frequency welding etc. fixed with each otherly, also can be designed to like this.If clamping device 13 and 14 only is designed to the part in addition of appointment is pressed in as shown in Figure 1 position together, the size of spring must be decided to be so: in the process of moulding action, can make at least these in addition parts be fixed together.
The clamping device 13 of position shown in Figure 1 protrudes from upper mould part, its clamping surface extends to from the very near place of the lower surface of upper mould part always, even extend in this plane, and the lower surface of upper mould part is parallel and nestle up the clamping plane E of hold-down frame 16 always.
Clamping device 14 protrudes from lower mould part 12, and its overhang is identical from the length that upper mould part 11 protrudes with clamping device 13 basically.
Fig. 6 is the plan view from above of device shown in Figure 1 and some annexes.This device is designed to four column pressure machines, and its four pillars 17 are positioned near four angles of rectangular graph.
Vertical line below forcing press is represented conveyer belt 18, and it is delivered on the forcing press by the steering handle liner plate blank 2 of arrow R indication.Before entering forcing press, blank is originally that cold blank is heated at this, and then delivers on the former by a hot spot 19.This device of last direction by Fig. 6 provides a hold-down frame 16, is carrying two sections 7 and 8 on the framework, and they are corresponding with the shaped component shown in Fig. 3.
By this method of the invention process the time, earlier two or polylith section are pressed on the hold-down frame 16 by desired position, then hold-down frame 16 is fixed on the upper mould part 11, this moment, upper mould part 11 was upwards mentioned the spare space that breaks away from lower mould part 12, thereby made the section that is pressed in the clamping plane E nestle up the lower surface of upper mould part 11 or the clamping surface of clamping device 13 respectively.In clamping plane E, hold-down frame 16 can be arranged in any suitable manner, and the tension force that is pressed in the section on the framework also can be regulated as required.May require that as some cladding material of section or the liner plate of some shape the line between the section is arc shape and compress, compensate the dislocation of line in molding procedure with this, thereby make final shaped component that a straight line be arranged.
In this position, liner plate 2 only is in contact with one another along line 4 with section 7 and 8, and they are pressed together on line 4, even can adopt the means that resemble welding and so on to be fixed together.If desired, the collaborative clamping surface on the clamping element 13 and 14 can process surface detail, thus can on line, impress out same decorative pattern or increase this zone in static friction.
In the section that liner plate has compressed or after being fixed together along connecting line, upper mould part descends to carry out forming process with hold-down frame.When stamper component during molding procedure mutually near the time, clamping device 13 and 14 is pushed length by length to be got back in the corresponding stamper component.When upper mould part 11 dropped to the extreme lower position that makes the liner plate final molding above lower mould part 12, because the pressure effect in the molding procedure, section was fixed on the liner plate.Because before processing and forming began, the relative position of liner plate and section is fixing along line 4, can affirm: the shape by clamping device 13 and 14 lines of determining just can accurately remain.In illustrated embodiment, line 4 extends along the bottom of grooving 9.In this case, compare with distinct methods discussed above, the moulding of its liner plate occurs over just after the fixing and section in mutual alignment between the section has been fixed on the liner plate, accurately is positioned at the bottom of grooving so can guarantee line.And, just needn't use cover fillet to cover it just because of the arrangement of line is very accurate.When molding procedure finished, upper mould part 11 turned back to the ready position after its rising, thereby the shaped component of having made 1 can be unloaded from this device, and so far, clamping device 14 can play the effect of a real ejector.
Fig. 4 represents: a liner plate not only can cover two sections, but also can cover 3 or 4 sections respectively.When making this class shaped component, before fixedly operation begins, the method that preferably adopts earlier between the section and resemble stitching, welding, glueds joint and so on links together, and can be fixed on section on the hold-down frame by method previously discussed then, for next step operation is got ready.
Same technical process also can be used on as shown in Figure 5 the shaped component, and on this class A of geometric unitA, the line between two sections is made up of straight line and a waveform curve.
The technical process of cladding material discussed above is not under any circumstance all to need to use hold-down frame, and supplying with material in a continuous manner with spool as shown in Figure 7 also is that possible Fig. 7 is the plan view from above that is similar to four column pressure machines shown in Figure 6.Carry the process of lining material also identical, therefore needn't give unnecessary details.
The difference of embodiment shown in Figure 7 is to cut into slices and 7 and 8 is provided by a spool.Before covering fabric 20 was wrapped on the spool, two sections linked together along the line between them, and this line is parallel to the length direction of covering fabric 20.Spool is installed in a fixed position, and it is again movably, makes supply pillar pressure fabric 20 rectangular with throughput direction R like this.Among the figure 21 expression tensioning facility, it can make fabric 20 vertically keep certain force of strain.The rotation of spool 22 is controlled by the device of brake one class, thereby makes fabric 20 be in tensioning state.
Owing to adopt fabric 20, the section of one-tenth is supplied with cladding material continuously.In order to make cladding material keep tensioning state in process, width of fabric can be done and can be left some edge strips like this than covering the wideer of 1 actual needs of shaped component, and these edge strips can roll passes to the covering fabric of processing to pulling force.Can then just enough cover shaped component if the width of fabric 20 is just in time made, tensioning facility 21 just must be designed to can be connected on the front end of fabric after each covering process so.
In represented in the accompanying drawings all embodiment, cutting tool 23 (referring to Fig. 1) can be installed, it can repair the ledge of cladding material and liner plate when molding procedure finishes, if necessary, but the cutting tool edge of smoothing shaping workpiece also.
Represented device is substantially similar to the device that Fig. 7 describes among Fig. 8; Therefore difference between them only is discussed here, and among the figure, identical parts are represented with same reference numeral.
Main difference between these two embodiment is to provide two sections 7 different with 8 mode for them.In the embodiment of Fig. 8, cladding material 7 and 8 is also provided by spool 22, but they do not interconnect or be fixed together, and processes in the building mortion but overlap to deliver to; This mode is similar to the content of embodiment represented among Fig. 1 of having discussed and Fig. 6 or Fig. 7.
Should be mentioned in that in device shown in Figure 8, cover section 7 and 8 and both can be rolled onto on the spool 22, also can between spool 22 and building mortion 1, adorn a ways and form the layer that coincides with the form of overlap joint.
Also should further mention, in all already mentioned embodiment, all exist the possibility with the relation of coinciding or seam relation is made in the section of cladding material along their line; Also can be before process operation, fixed with each other cladding material.Under latter event, section also can along its line bend to backwards their this on one's body.Certainly also exist the possibility that stands away between the section, in this case, liner plate is visible on the line that they separate.
According to the present invention, always exist before inserting hold-down frame or insert before the aftershaping operation or the possibility of in molding procedure, section being fixed or coupling together by its line.
For reaching this purpose, clamping device can be made the device as high-frequency electrode.
The specific product of Fig. 9 and Figure 10 is consistent therefore with the product shown in Fig. 2 and Fig. 3 basically, and identical or corresponding parts all use same reference number to represent.Reference number about the basic structure of wall liner member among the figure is to make by the explanation of front.The specific product of the shaped component of Fig. 9 and Figure 10 and Fig. 3 and Fig. 4 has two places different, the one, the former is equipped with a upholstery layer 27 on the total length at edge 28 at an upper portion thereof, another is that another piece upholstery layer 27 is housed on the lower limb of the recess 25 of handle, two upholstery layers all are contained between section and the liner plate 2, live first cladding material section 7 in order to pad.
These upholstery layers can be made with the section of section bar or compressible material, preferably adopt the foamed material that is easy to be glued onto on cladding material or the liner plate.
When the shaped component of making as shown in the figure, inner cover 27 can be fixed on the cladding material earlier, thereby can use them on the domain of dependence of liner plate.
In an example shown, liner plate is made by thermoplastic, closely is fixed together if wish interior material and liner plate, and decorative layer preferably is used in the material that is easy to be glued onto under the hot effect on the liner plate.
Make as Fig. 9 and the operating process that shaped component adopted shown in Figure 10, identical with the shaped component of making as shown in Figures 2 and 3 basically; But before use section 7, upholstery layer 27 is fixed on the cladding material with the method for glueing joint or weld earlier.
In final forming operation process, affixed state is owing to the effect of heat can further strengthen between interior material and cladding material or the liner plate.
