Description

o 146586o 146586

Den foreliggende opfindelse angår en fremgangsmåde til forbindelse af mod hinanden liggende rande af plader som angivet i den indledende del af krav 1.The present invention relates to a method of joining adjacent edges of sheets as set forth in the preamble of claim 1.

Ved en kendt fremgangsmåde er det næste arbejds-5 trin efter de foran angivne, at randpartiet bukkes færdigt.In a known method, the next working step after the above is that the edge portion is bent.

I det påfølgende arbejdstrin bukkes de ved enden af de op-bukkede randpartier liggende randpartier en vinkel på omkring 45° og videre i tilslutning hertil, indtil de næsten ligger an mod de opbukkede randpartier, og et sidste arbejdstrin 10 tjener til færdiggørelse af falsen. Ved denne fremgangsmåde er der den ulempe, at det frie endeparti fjedrer tilbage og ødelægger de efterfølgende arbejdstrin. Denne fremgangsmåde er onj-handlet i beskrivelsen til USA-patent nr. 3.610.191.In the subsequent working step, the edge portions lying at the end of the curved edge portions are bent at an angle of about 45 ° and thereafter until they are almost in contact with the curved edge portions and a final working step 10 serves to complete the seam. In this method, there is the disadvantage that the free end portion springs back and destroys the subsequent working steps. This process is described in U.S. Patent No. 3,610,191.

Formålet med den foreliggende opfindelse er med så få 15 udvidelser af arbejdstrinene som muligt at hindre den ugunstige tilbagefjedring af det bukkede frie endeparti. Dette formål opnås ifølge opfindelsen ved hjælp af det i den kendetegnende del af krav 1 angivne. Ved skråstillingen af de to opbukkede randpartier bringes det samtidig færdigt indbukkede randparti bragt 20 i en stilling, i hvilken det er hindret i tilbagefjedring, og derved kan det næste arbejdstrin udføres uforstyrret.The object of the present invention is, with as few extensions of the working steps as possible, to prevent the unfavorable return of the bent free end portion. This object is achieved according to the invention by means of the characterizing part of claim 1. In the sloping position of the two bent edge portions, the simultaneously finished bent edge portion is brought 20 to a position in which it is hindered in spring resilience, and thus the next working step can be carried out undisturbed.

Fremgangsmåden kan ifølge opfindelsen hensigtsmæssigt udføres som angivet i den kendetegnende del af krav 2.The method according to the invention may conveniently be carried out as set forth in the characterizing part of claim 2.

Herved hindres falsen i ved ydre kraftpåvirkning at trykkes 25 fladt mod selve pladerne og giver også disse et vist modstandsmoment .This prevents the seam from being pressed flat against the plates themselves by external force and also gives them a certain resistance moment.

Ppfindelsen skal forklares nærmere i det følgende under henvisning til tegningen, på hvilken der skematisk er vist et apparat til forbindelse af to med hinanden liggende 30 rande af to plane metalplader efter fremgangsmåden ifølge opfindelsen, idet fig. 1 viser et sidebillede af apparatet, fig. 2 randene af to plader i udgangsstillingen, fig. 3 et snit efter linien III-III i fig. 1 med 35 indlagte, til fig. 2 svarende plader og o 2 146586 fig. 4 til 6 snit efter linierne IV-XV, V-V og VI-VI i fig. 1 med tilsvarende formede plader.The invention will be explained in more detail below with reference to the drawing, in which an apparatus is shown schematically for connecting two adjacent 30 edges of two flat metal sheets according to the method according to the invention, fig. 1 is a side view of the apparatus; FIG. 2 shows the edges of two plates in the initial position; FIG. 3 is a sectional view taken along line III-III of FIG. 1 with 35 inlets, FIG. 2 corresponding plates and Figs. 4 to 6 are sections along lines IV-XV, V-V and VI-VI of FIG. 1 with similarly shaped plates.

På en ramme 1 er fire par valser 2 til 9 lejret drejeligt og indstilleligt i højden. Valserne i et valsepar 5 er ved hjælp af tandhjul forbundet med hinanden, så at de slutter formmæssigt til hinanden. En af valserne af hvert valsepar kan ved hjælp af en kæde drives fra det nærmeste valsepar, og hver kæde forbinder kun to ved siden af hinanden værende valsepar. Et af de med valserne 2 til 9 i 10 drejningsmæssig henseende fast forbundet tandhjul er forbundet drejningsmæssigt fast med en drivmotor. Valserne 2 til 9 kan således drives med samme omdrejningstal.On a frame 1, four pairs of rollers 2 to 9 are rotatable and adjustable in height. The rollers in a pair of rollers 5 are connected to each other by means of gears so that they form together. One of the rollers of each pair of rolls can be driven by means of a chain from the nearest pair of rolls, and each chain connects only two adjacent pair of rolls. One of the gears fixed in rotation with respect to the rollers 2 to 9 in 10 is connected in rotation with a drive motor. The rollers 2 to 9 can thus be operated at the same speed.

Fig. 2 visér i tværsnit to plader 11 og 12, som skal forbindes med hinanden. Pladen 11 har tre kantbukninger 13 til 15 15, hver bukket en vinkel på 90°, og kantbukningerne 14 og 15 er bukket i samme retning og kantbukningen 13 i modsat retning. Pladen 12 har to, hver 90° i samme retning bukkede kantbukninger 16 og 17. Kantbukningerne 13, 14 og 16, 17 såvel som fortrinsvis også 14, 15 er fjernet lige langt fra 20 hinanden. De frie ender af pladerne 11 og 12 er betegnet med 18 og 19 og de mellem kantbukningerne liggende områder med 21, 22 resp. 23. Længden af de frie ender er noget kortere end afstandene mellem kantbukningerne 13, 14; 16, 17 resp. 14, 15. Pladerne 11 og 12 kan med undtagelse af kant-25 bukningerne være bukket plant eller om en parallelt med kantbukningerne forløbende akse. Det er også muligt, at de med kantbukningerne 13 til 17 forsynede plader 11, 12 under den i fig. 3 til 6 anskueliggjorte sammenfalsning af deres rande 19, 21, 22 og 18, 23 bukkes omkring en akse, der står 30 vinkelret på områderne 21 og 23 i fig. 2. Den færdige fals kan altså i et færdigt rør forløbe parallelt med dettes længdeakse, ringformet omkring dets omkreds eller skrueformet omkring dets omkreds.FIG. 2 shows in cross section two plates 11 and 12 to be connected. The plate 11 has three edge bends 13 to 15 15, each bent at an angle of 90 °, and the edge bends 14 and 15 are bent in the same direction and the edge bend 13 in the opposite direction. The plate 12 has two, each 90 ° in the same direction, curved edge bends 16 and 17. The edge bends 13, 14 and 16, 17 as well as preferably also 14, 15 are removed equally far from each other. The free ends of the plates 11 and 12 are designated 18 and 19 and the areas between the edge bends 21, 22 and 23. The length of the free ends is somewhat shorter than the distances between the edge bends 13, 14; 16, 17 and 14, 15. The plates 11 and 12, with the exception of the edge 25 bends, can be bent flat or on an axis extending parallel to the edge bends. It is also possible that the plates 11, 12 provided with the edge bends 13, 17 under the arrangement shown in FIG. 3 to 6 illustrate collapsing of their edges 19, 21, 22 and 18, 23 bending around an axis 30 perpendicular to regions 21 and 23 of FIG. 2. The finished seam can thus extend in a finished pipe parallel to its longitudinal axis, annular around its circumference or helical about its circumference.

Ved hjælp af valserne 2, 3 bukkes den frie ende 19 35 en vinkel på mellem 15 og 80°, specielt mellem 30 og 60°C.By means of the rollers 2, 3 the free end 19 35 is bent at an angle between 15 and 80 °, especially between 30 and 60 ° C.

Hertil har valsen 3 en mellem to flanger anbragt ringnot 27, som har en skrå væg 28 og en vinkelret på drejningsaksen for- 3 o 146586 løbende væg 29. Valsen 2 er udformet cylindrisk.To this end, the roller 3 has a ring groove 27 between two flanges, which has an inclined wall 28 and a perpendicular wall of the axis of rotation of the wall 29. The roller 2 is cylindrical in shape.

Ved den næste arbejdsoperation svarende til fig. 4 lægges den frie ende 19 mod den frie ende 18, og områderne 21, 23 bukkes en vinkel på mellem 15 og 75°, navnlig 5 mellem 30 og 60°, i retning mod pladen 11. Hertil har valsen 4 en ringnot 30 med en skråt forløbende væg 31 og med en vinkelret på drejningsaksen forløbende væg 32, hvoraf væggen 31 ligger an mod området 21 og væggen 32 mod området 22.In the next operation similar to FIG. 4, the free end 19 is laid against the free end 18, and the areas 21, 23 are bent at an angle of between 15 and 75 °, in particular 5 between 30 and 60 °, towards the plate 11. For this, the roller 4 has a ring groove 30 with a inclined wall 31 with a wall 32 perpendicular to the axis of rotation, the wall 31 abutting the area 21 and the wall 32 facing the area 22.

Valsen 5 har en ringvulst 33, som med en skrå flade 34 10 ligger an mod området 23 og med en vinkelret på aksen stående væg 35 ligger an mod den frie ende 19. Valserne 4 og 5 har desuden flanger 36 og 37, af hvilke flangen 36 har den mod området 22 anliggende og ringnoten 30 begrænsende væg 32.The roll 5 has an annular bead 33 which, with an inclined surface 34 10, abuts the region 23 and with a wall 35 perpendicular to the axis, abuts the free end 19. The rollers 4 and 5 also have flanges 36 and 37, of which the flange 36 has the wall 32 abutting the area 22 and the ring groove 30.

Som følge af bukningen af området 23 griber den frie 15 ende 19 ind i en spids vinkel og er derfor hindret i tilbage-fjedring. Endvidere sørger væggen 32 for, at området 22 ved indbukning af den frie ende 19 ved hjælp af valsen 5 ikke trykkes i retning mod valsen 4.As a result of the bending of the region 23, the free end 19 engages at an acute angle and is therefore hindered in back suspension. Furthermore, the wall 32 ensures that the area 22, when the free end 19 is folded in by the roller 5, is not pressed in the direction towards the roller 4.

Valseparret 6, 7 tjener til, at de frie ender 18, 19 20 såvel som området 22 og områderne 21 og 23 lægges parallelt, og at den frie ende 19 lægger sig an mod området 23. Til dette formål har valsen 6 en ringnot 41 med en skrå væg 42 og valsen 7 en med ringnoten 41 samarbejdende ringvulst 43 med en tilsvarende skrå væg 44. Valserne 6 og 7 har desuden 25 ringflanger 45 og 46.The roller pair 6, 7 serves for the free ends 18, 19 20 as well as the region 22 and the areas 21 and 23 to be parallel and the free end 19 abutting against the region 23. For this purpose, the roller 6 has a ring groove 41 with a sloping wall 42 and the roller 7, a ring bead 43 cooperating with the ring groove 41 with a corresponding sloping wall 44. The rollers 6 and 7 also have 25 ring flanges 45 and 46.

I den næste arbejdsoperation stilles falsen ved hjælp af de cylindriske valser 8 og 9 vinkelret på pladerne 11 og 12.In the next working operation, the seam is positioned perpendicular to the plates 11 and 12 by means of the cylindrical rollers 8 and 9.

Medens ringnoten 27 i valsen 3 ligger på den ene side 30 af de bearbejdede dele 18, 19, 21, 22 og 23, befinder ringnoterne 30 og 41 i valserne 4 og 6 sig på den anden side.While the ring groove 27 of the roll 3 is on one side 30 of the machined parts 18, 19, 21, 22 and 23, the ring grooves 30 and 41 of the rollers 4 and 6 are on the other side.

I stedet for med valser kan pladerandene også deformeres ved hjælp af prægeværktøjer eller lignende på den forud beskrevne måde. Benyttes der til deformering af pladerandene 35 kun prægeværktøjer, kræves der i tilslutning hertil også transportvalser.Instead of rollers, the plate edges can also be deformed by means of embossing tools or the like in the manner described above. If deformation of the plate edges 35 is only used for embossing tools, transport rolls are also required in connection therewith.
