Description

Opfindelsen angår en fremgangsmåde til opspænding af en første plade, som er indfældet i en i en anden plade udformet fals, som forløber langs en hulrand, hvilken første plade fæstnes til falsen ved hjælp af klæbestof, samt et opspændingsmiddel til brug ved udøvelse af fremgangsmåden.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a method of clamping a first plate which is folded into a seam formed in a second plate which extends along a hollow rim, the first plate being secured to the seam by adhesive, and a clamping means for use in the practice.

Den stadigt stigende anvendelse af klæbede samlinger især inden for bilbranchen, hvor klæbestof anvendes til samling af karroseridele, øger behovet for opspændingssystemer til sammenholdelse af delene under klæbestoffets hærdning.The ever-increasing use of adhesive joints, especially in the automotive industry, where adhesive is used to assemble car body parts, increases the need for clamping systems to match the parts during adhesive curing.

Fordelen ved klæbede samlinger er den gode vedhæftning, som klæbestoffet har, selv hvor delene er tynde for eksempel på grund af tæring, og hvor man ikke ville kunne gennemføre en reparation med tilfredsstillende resultat, for eksempel ved at svejse delene sammen. Hertil kommer fordelene ved den kolde klæbestofsamling, som ikke kræver fjernelse af kabler, bagbeklædning, polstring m.m.The advantage of adhesive joints is the good adhesion that the adhesive has, even where the parts are thin, for example due to corrosion, and where a repair with a satisfactory result would not be possible, for example by welding the parts together. In addition, the benefits of the cold adhesive collection, which does not require the removal of cables, backing, upholstery etc.

Fremgangsmåden er i øvrigt den, at den ene del, for eksempel ved hjælp af en håndfalsetang, forsynes med en indfal-set rand, som forløber langs samlingsstedet. I denne rand anbringes den anden del, således at overfladerne på delene er plan. Kontaktområdet mellem delene er forinden forsynet med klæbestof, og delene skal nu opspændes således, at de sammenpresses, medens klæbestoffet hærder.Furthermore, the method is that one part, for example by means of a hand forceps, is provided with a flared edge extending along the assembly point. In this rim, the second part is placed so that the surfaces of the parts are flat. The contact area between the parts is previously provided with adhesive and the parts must now be clamped so that they are compressed while the adhesive hardens.

Hertil anvendes normalt forskellige former for opspændingsværktøjer i form af leddelte stangsystemer, som er hæftet til den ene karrosseridel, for eksempel ved hjælp af en sugekop, magnet, selvklæber og lignende midler. En yderligere del af opspændingsværktøjet udøver et tryk mod den anden karrosseridel, hvilket tilsammen giver opspændingen .For this, various types of clamping tools are usually used in the form of articulated rod systems, which are attached to one body part, for example by means of a suction cup, magnet, self-adhesive and similar means. A further part of the clamping tool exerts a pressure on the other body part, which together gives the clamping.

Dette udstyr til opspænding af karrosseridele er imidlertid forholdsvis kompliceret, da det skal kunne tilpasse sig efter plane og buede karrosseriformer og derfor må være indstilbart i mindst to planer.However, this equipment for clamping body parts is relatively complicated, as it must be able to adapt to flat and curved body shapes and must therefore be adjustable in at least two planes.

Endvidere kræves der ofte en del kostbart ekstraudstyr, såsom vacuumpumper og jævnstrømsgeneratorer, for at opnå vedhæftning via sugekopper eller magneter.In addition, some expensive accessories, such as vacuum pumps and direct current generators, are often required to achieve suction cup or magnet attachment.

Anvendelsen af disse opspændingsværktøjer har derfor hidtil i nogen grad begrænset brugen af klæbestof som sammenbindingsmiddel, trods de helt klare fordele, som denne samlingsmetode har i forhold til svejsning, nitning og lignende former for samling.The use of these clamping tools has, to date, to some extent limited the use of adhesive as a bonding agent, despite the clear advantages that this assembly method has in relation to welding, riveting and similar types of assembly.

Fra DE offentliggørelsesskrift nr. 2.520.996 kendes en indretning til kraftbetonet samling mellem to med huller forsynede byggedele, hvilken indretning omfatter en klemplade med i det mindste én slids, der i den ene ende udmunder i cirkulær boring, og i det mindste én nitte, hvis skaftdel er forsynet med riller. Denne kendte indretning går ud på, at nitten eller nitterne stikkes gennem samvirkende huller i de to byggedele med hovedet eller hovederne i anlæg mod bagsiden af den ene byggedel, hvorefter klempladens nøglehulsformede udskæring anbringes på den eller de fra byggedelene udragende ende eller ender, idet klempladens overside lige som rillerne i nitten eller nitterne forløber skråt i forhold til byggedelenes overflade på en sådan måde, at der dels opnås en kraftbetonet kilevirkning ved forskydning af klempladen i nævnte riller og dels opnås en selvspærrende virkning.DE Publication No. 2,520,996 discloses a device for power-driven jointing between two holes, which comprises a clamping plate with at least one slot, which ends at one end in circular bore, and at least one rivet, if the shaft part is provided with grooves. This known device is that the rivets or rivets are inserted through cooperating holes in the two building parts with the head or heads in contact with the back of one building part, after which the keyhole-shaped cut of the clamp plate is placed on the end or ends protruding from the building parts. top side just as the grooves in the rivets or rivets extend obliquely to the surface of the building parts in such a way that a force-driven wedge effect is obtained by displacing the clamping plate in said grooves and partly a self-locking effect is obtained.

Denne kendte fremgangsmåde er alene beregnet til at sammenholde byggedele på en anden måde end tidligere, hvor man til aftagelig fastholdelse har anvendt skrue-møtrik-samlinger baseret på gevindforbindelser, hvis svaghed ligger i, at skruerne let arbejder sig løse under vibrationspåvirkning .This known method is only intended to compare construction parts in a different way than before, where screw-nut assemblies based on threaded joints have been used for removable retention, the weakness of which is that the screws easily loosen under vibration.

Denne kendte indretning er uegnet til brug ved reparation af karosseridele på køretøjer, hvor man efter reparationen ikke må kunne se spor efter den udførte reparation, når de nye dele er blevet overfladebehandlet.This known device is unsuitable for use in the repair of body parts on vehicles where, after the repair, it is not possible to see traces of the repair done after the new parts have been surface treated.

Det er opfindelsens formål at afhjælpe disse mangler ved de kendte fremgangsmåder, og dette opnås ved en fremgangsmåde, der er særegen ved, at man anvender rotationssymmetriske nitter med et nittehoved ved den tykkeste ene ende af et konisk skaft, der i dets modstående tyndeste anden ende har i yderligere hoved, hvilken tykkeste ene ende af skaftet har en forud fastsat første diameter, at der i falsen tildannes første huller med til nævnte første diameter svarende diameter, at nitterne indskydes i nævnte første huller med nittehovedet til anlæg mod falsens bagside, at der i den første plade udføres med nævnte første huller samvirkbare andre huller med en anden diameter, som er større end nævnte første diameter, at den første plade anbringes i den med klæbestof belagte fals med nitternes skafter og nævnte yderligere hoveder ragende gennem nævnte andre huller, at man anvender aflange klemstykker, der i området ved deres midte har en langsgående slids med en til nævnte skafters tyndeste anden ende svarende bredde, hvilken slids ved sin ene ende udmunder i en boring med en i forhold til et yderligere hoveds diameter en anelse større diameter, hvorhos klemstykkerne omfatter spændemid-ler til at presse dem bort fra pladerne, at man anbringer klemstykkerne med slidsen gribende omkring den tyndeste anden ende af et skaft på en nitte med det yderligere hoved i anlæg mod den bort fra pladerne vendende side af klemstykket, hvorefter klemstykkerne spændes bort fra pladerne, og at nitterne efter klæbestoffets afhærdning og efter fjernelse af klemstykkerne afkortes i niveau med pladerne.It is an object of the invention to remedy these deficiencies by the known methods, and this is achieved by a method which is peculiar to the use of rotationally symmetrical rivets with a rivet head at the thickest one end of a conical shaft which at its opposite thinnest end has in additional head, which thickest one end of the shaft has a predetermined first diameter, that first holes of the diameter corresponding to said first diameter are formed in the seam, that the rivets are inserted into said first holes with the rivet head for abutment towards the back of the seam, that in the first plate, co-operable second holes having a second diameter larger than said first diameter are provided with said first plate being placed in the adhesive-coated seam with the rivets' shafts and said additional heads projecting through said second holes; one uses elongated clamps that have a longitudinal slot in the area at their center with an additional the thinner second end corresponding to the width of said shank, which slits at one end thereof into a bore having a slightly larger diameter in relation to a further head diameter, the clamping pieces comprising clamping means for pressing them away from the plates, placing the clamping pieces with the slit gripping about the thinnest other end of a shank of a rivet with the additional head abutting against the side facing away from the plates, after which the clamps are clamped away from the plates and the rivets are cut short after removal of the adhesive and after removal of the clamps. level with the plates.

Herved opnås på en overraskende enkel måde en opspænding af delene helt uden brug af yderligere eksterne hæftemidler for opspændingsværktøjet, idet nitterne helt erstatter de kendte hæftemidler ved alene at trække i nitten, hvorved klemstykkerne kan trykke som reaktion mod området omkring nitten, og dermed den ene karrosseridel mod den underliggende karrosseridel. Der kan derfor ved denne fremgangsmåde anbringes nitter rundt langs samlingen på de mest hensigtsmæssige steder, og derved opnås den ønskede opspænding ved tryk på de udvalgte steder. Endvidere vil nitterne hjælpe med til at styre den ene del, indtil opspændingen er gennemført, hvilket letter håndteringen af delene, medens klæbestoffet er flydende. Da fremgangsmåden ikke kræver særligt udstyr, er den tillige billig og derfor overkommelig for de fleste reparatører.Hereby, a surprisingly simple way is obtained to clamp the parts completely without the use of additional external adhesives for the clamping tool, the rivets completely replacing the known staples by only pulling the rivet, whereby the clamps can press in response to the area around the rivet, and thus the one body part against the underlying body part. Therefore, by this method, rivets can be arranged around the joint at the most convenient locations, thereby obtaining the desired clamping pressure at the selected locations. Furthermore, the rivets will help control one part until the clamping is completed, which facilitates handling of the parts while the adhesive is liquid. Since the procedure does not require special equipment, it is also inexpensive and therefore affordable for most repairers.

Ved at anvende det i krav 2 omhandlede opspændingsmiddel omfattende en særlig form for nitte og et hertil afpasset klemstykke, som dels ligger an mod nittens ydre hoved og dels ved hjælp af ben kan trykke mod delene, kan man hurtigt og enkelt opspænde delene.By using the clamping means according to claim 2, comprising a special form of rivet and a suitable clamping piece, which partly touches the outer head of the rivet and partly by means of legs can push against the parts, the parts can be fast and easily clamped.

Ved, som omhandlet i krav 3 og 4, at anvende et klemstykke med en udskæring for nittens hoved samt en fod og en i længden indstillelig fod, kan man ved blot en skruebevægelse opspænde delene, og ligeså enkelt fjerne klemstykket igen, når klæbestoffet er hærdet, og genbruge klemstykket ved en senere lejlighed.By using a clamping piece with a cutout for the rivet's head as well as a foot and a length adjustable foot, as claimed in claims 3 and 4, the parts can be clamped by a simple screw movement and also simply remove the clamping piece once the adhesive has hardened. , and reuse the clip at a later date.

Opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, hvorThe invention will now be described in more detail with reference to the accompanying drawings, in which:

Fig. 1 viser en opspænding set udefra af en rektangulær pladedel med et enkelt klemstykke monteret,FIG. 1 shows an exterior view of a rectangular plate part with a single clamping piece mounted,

Fig. 2 viser klemstykket set i perspektiv, ogFIG. 2 is a perspective view of the clamp, and

Fig. 3 viser et snit gennem klemstykket set i retning III-III i fig. 1 På tegningen er vist et eksempel på en udførelsesform for fremgangsmåden ved hjælp af klemstykker 11.FIG. 3 shows a section through the clamping piece seen in direction III-III in fig. 1 The drawing shows an example of an embodiment of the method by means of clamping pieces 11.

På fig. 2 og 3 ses, hvorledes klemstykkerne er opbygget. I det viste eksempel er klemstykket fremstillet af metalplade, som er ombukket langs alle fire sider, så de tre sider 16 er korte, medens den fjerde side er så lang, at det ombukkede stykke 15 danner en fod, som kan berøre pladen 10, som det fremgår af tegningen, når klemstykket er monteret.In FIG. 2 and 3, see how the clamps are constructed. In the example shown, the clamping piece is made of metal plate which is folded along all four sides so that the three sides 16 are short, while the fourth side is so long that the folded piece 15 forms a foot which can touch the plate 10 which it is shown in the drawing when the clamping piece is mounted.

Modsat det ombukkede fodstykke 15 på klemstykket er der skåret et gevindhul, hvori en skrue med en fod 12 kan forskydes i længderetningen og således skrues til anlæg mod pladen 10, når opspændingen skal foretages.Opposite the folded foot piece 15 of the clamping piece, a threaded hole is cut in which a screw with a foot 12 can be displaced longitudinally and thus screwed into abutment against the plate 10 when the clamping is to be carried out.

For at lette betjeningen af denne skrue er den ved enden forsynet med en håndgreb 13 af kunststof eller lignende materiale.To facilitate the operation of this screw, it is provided at the end with a handle 13 of plastic or similar material.

Endelig er der ved midten af klemstykket 11 udformet et nøglehulsformet hul 14, som i sit store hulafsnit tillader passage af et nittehoved 8, som ved forskydning af klemstykket 11 kan skydes ind i det lille hulafsnit, hvor hovedet 8 ligger an mod klemstykkets 11 overside, som det tydeligt ses på fig. 3.Finally, at the center of the clamping piece 11, a keyhole shaped hole 14 is formed which permits in its large hole section passage of a rivet head 8 which, by displacement of the clamping piece 11, can be slid into the small hollow section where the head 8 abuts the upper side of the clamping piece 11. as seen clearly in FIG. Third

Nitten 7 ses endvidere tydeligt på snitbilledet i fig. 3, og består af et konisk skaft 7, som ved den tykkeste ene ende er forsynet med et hoved 6, og i den modstående tyndeste anden ende med det yderligere hoved 8.The rivet 7 is also clearly seen in the sectional view of FIG. 3, and consists of a tapered shaft 7 which is provided with a head 6 at the thickest one end, and at the opposite thinnest other end with the additional head 8.

Fremgangsmåden vil herefter blive nærmere beskrevet.The process will then be described in more detail.

Pladestykket 10, som skal opspændes og fæstnes ved hjælp af klæbestof, anbringes oven på den bestående pladedel 1. Herefter afmærkes det område 2, som skal forsynes med en indfældet fals 3. Denne fremstilles normalt ved hjælp af en håndfalsetang og er således dimensioneret, at pladestykket 10, når det er placeret i falsen, ligger plant med pladen 1, se fig. 3.The plate piece 10, which is to be clamped and fastened by adhesive, is placed on top of the existing plate part 1. Next, the area 2 to be provided with a recessed socket 3. This is usually manufactured by means of a hand-held pliers and is dimensioned so that the plate piece 10, when placed in the fold, lies flat with the plate 1, see fig. Third

Herefter laves der huller 4 i pladen 10, hvilke huller kan være lidt større end nitternes skaft 7.Next, holes 4 are made in the plate 10, which holes may be slightly larger than the shaft 7 of the rivets.

I falsen 3 laves endvidere huller 5, som i størrelse svarer til den tykkeste ene ende af skaftet 7, således at nitterne 7 kan slås eller presses ind i hullerne 5, og fastholdes ved klemning.In the groove 3, holes 5 are also made which correspond in size to the thickest one end of the shaft 7, so that the rivets 7 can be punched or pressed into the holes 5 and retained by squeezing.

Når falsen er blevet forsynet med det ønskede antal nitter, smøres der klæbestof 9 ud på falsen 3. Herefter pla- ceres pladen 10 over nitterne i falsen, og man kan begynde at montere klemstykkerne 11.When the ridge has been provided with the desired number of rivets, adhesive 9 is lubricated on the ridge 3. Then the plate 10 is placed over the rivets in the ridge and the clamps 11 can be started.

Disse skydes ind under nittehovedet 8, og når de er placeret hensigtsmæssigt i forhold til pladerne, drejes skruen 12, 13 ned til trykning mod pladen. Jo mere denne skrue tilspændes, jo kraftigere blivere sammentrykningen. Når alle klemstykkerne er monteret, er pladen opspændt på en enkel og nem måde.These are inserted under the rivet head 8 and when positioned appropriately with respect to the plates, the screws 12, 13 are turned down to press against the plate. The more this screw is tightened, the stronger the compression becomes. When all the clamps are mounted, the plate is clamped in a simple and easy way.

Efter at klæbestoffet 9 er hærdet, kan alle skruerne 12 løsnes, og klemstykkerne 11 kan forskydes og fjernes fra nitterne. Herefter klippes eller skæres nitterne over i et niveau 17 med pladerne.After the adhesive 9 is cured, all the screws 12 can be loosened and the clamping pieces 11 can be displaced and removed from the rivets. The rivets are then cut or cut to a level 17 with the plates.

Samlingen er nu gennemført, og man kan på sædvanlig måde slibe, spartle og lakere efter behov. Det eneste, der forbruges af materialer, er således nitter og lim, og da klemstykkerne 11 er relativt billige at producere, kan klæbestofsamlingen ved hjælp af dette opspændingsværktøj ske på en hidtil ukendt økonomisk måde.The collection is now complete, and you can grind, putty and varnish in the usual way as needed. Thus, the only thing consumed by materials is rivets and glue, and since the clamps 11 are relatively inexpensive to produce, the adhesive assembly can be made by this clamping tool in a novel economic way.
