Abstract
Description
m m o: »Q Us! co formningsrullar 15. l rullforrnningsenheten viks bandet successivt ihop till ett rör 16, vars längsgående skarv svetsas ihop med en svetsenhet 17 när röret passerar den stillastående svetsenheten. Röret kan ha cirkulärt tvärsnitt. Rullformningsenheten utgör samtidigt frammatningsanordning för stålbandet. m m o: »Q Us! co forming rollers 15. In the roller forming unit, the strip is successively folded together into a tube 16, the longitudinal joint of which is welded together with a welding unit 17 when the tube passes the stationary welding unit. The tube can have a circular cross section. The roll forming unit also constitutes a feed device for the steel strip.
Efter svetsenheten finns en schematiskt visad hydroformningsenhet 18 som har en form bestående av två formdelar, en övre 19 och en undre 20. Formen är i figur 1 visad stängd och den kan maskinellt öppnas genom att undre formdelen förflyttas nedåt som indikeras av pilen 21 och övre formdelen förflyttas uppåt som indikeras av pilen 22 i figur 3. I figur 2 visas inte formdelarna men deras inre form är indikerad med streckade linjer.After the welding unit there is a schematically shown hydroforming unit 18 which has a mold consisting of two mold parts, an upper 19 and a lower 20. The mold is shown closed in figure 1 and it can be opened mechanically by moving the lower mold part downwards as indicated by the arrow 21 and upper the mold part for fl is moved upwards as indicated by the arrow 22 in fi gur 3. In fi gur 2 the mold parts are not shown but their internal shape is indicated by dashed lines.
När röret 16 formas hålls formen 19,20 öppen så att i föregående tillverkningscykel hydroformad produkt 23 kan matas ut ur formen samtidigt som röret 16 kontinuerligt matas in i formen vartefter det tillverkas.When the tube 16 is formed, the mold 19,20 is kept open so that in the previous manufacturing cycle hydroformed product 23 can be fed out of the mold at the same time as the tube 16 is continuously fed into the mold as it is manufactured.
När redan hydroformad produkt 23 matats ut ur formen 19,20, såsom visas på figur 1, stoppas rörtillverkningen och röret 16 kapas med en kapenhet 24 som innefattar ett cirkelsågblad 25. Den bortkapade produkten 23 förs sedan bort på en utmatningsenhet 26. När produkten 23 har matats ut ur formen kan formen stängas kring röret 16 såsom visas i figur 1 och röret inuti formen kan hydroformas. l figur 1 visas produkten 23 innan den kapats bort, men figur 2 visas efter bortkapning av produkten 23.When already hydroformed product 23 is discharged from the mold 19,20, as shown in Figure 1, pipe production is stopped and the pipe 16 is cut with a cutting unit 24 comprising a circular saw blade 25. The cut product 23 is then removed to a dispensing unit 26. When the product 23 has been discharged from the mold, the mold can be closed around the tube 16 as shown in Figure 1 and the tube inside the mold can be hydroformed. Figure 1 shows the product 23 before it has been cut off, but Figure 2 is shown after cutting off the product 23.
Hydroformningen beskrivs bäst med hänvisning till figur 3. som visar stängd form 19,20 med en nyss formad produkt 27. I formens ingängsände finns en konisk stålring 30 som har passning mot röret 16 innervägg och är axiellt fast, men något radiellt elastiskt, monterad på en hållare i form av ett rör 31 med ekrar 29. Stålringen 30 tillåter röret att glida in genom den under tillverkningen av röret och ekrama 29 tillåter ringen att expandera. En stång 32 sträcker sig in genom röret 31 och stålringen 30 och bär en konisk plugg 33 som kan vara av stål. Som framgår av figur 1 finns ett stativ 34 placerat där röret 16 ännu ej slutits så att stativet kan bära röret 31 och stången 32. Rullformningsenheten har därför sin sista formningsstation efter stativet för att sluta rörprofilen 16, men denna sista forrnningsstation visas inte. (fi l\} CC* f) i, l CJ lformens 19,20 andra ände finns också en konisk stålring 35 och en konisk plugg 36.The hydroforming is best described with reference to Figure 3, which shows a closed mold 19,20 with a newly formed product 27. At the entrance end of the mold there is a conical steel ring 30 which fits against the inner wall of the tube 16 and is axially fixed, but slightly radially elastic, mounted on a holder in the form of a tube 31 with spokes 29. The steel ring 30 allows the tube to slide in through it during the manufacture of the tube and the spokes 29 allow the ring to expand. A rod 32 extends through the tube 31 and the steel ring 30 and carries a conical plug 33 which may be of steel. As shown in Figure 1, a frame 34 is placed where the tube 16 has not yet been closed so that the frame can support the tube 31 and the rod 32. The roll forming unit therefore has its last forming station after the frame for closing the tube profile 16, but this last forming station is not shown. There is also a conical steel ring 35 and a conical plug 36.
Pluggen 36 är fäst på en stång 37 och en tillförselkanal 38 för tryckmedium sträcker sig genom stången och pluggen. Pluggen 36 och stålringen 35 uppbärs av en arm 39 som är svängbar kring en axel I såsom visas i figur 2. Anordningen som bildas av detaljema 35-39 visas i figur 2 med plugg och stålring insvängda i röret 16 ände. Med streckade linjer visas anordningen 35-39 bortsvängd. Man kan alternativt tillföra tryckmedium genom den andra koniska pluggen 33.The plug 36 is attached to a rod 37 and a supply medium 38 for pressure medium extends through the rod and the plug. The plug 36 and the steel ring 35 are supported by an arm 39 which is pivotable about an axis I as shown in Figure 2. The device formed by the details 35-39 is shown in Figure 2 with the plug and steel ring pivoted into the end of the tube 16. Dashed lines show the device 35-39 inverted. Alternatively, pressure medium can be supplied through the second conical plug 33.
För att trycksätta röret 16 inuti formen 19,20 dras stängerna maskinellt utåt så att pluggarna 33,36 när ett initialläge där de tätar mot ringarna 30,35 och expanderar ringarna elastiskt till ett initialläge med tätning mot röret 16. Det är en fördel om ringarna expanderar till tätning eftersom det minskar läckaget och ger en initial friktion mot röret 16, men det är inte alldeles nödvändigt. Tryckmedium tillförs genom kanalen 38 och medietrycket ger pluggarna 33,36 en kraft utåt som påverkar ringarna iexpanderande riktning så att de får ökad normalkraft mot röret 16, som har radiellt stöd mot formen 19,20. Ekrarna 29 tillåter denna expansion av ringen 30. Man får på detta sätt en självlåsning av ändtätningarna och man behöver inte anlägga så stor extern axiell kraft för att få tätning. Åndtätningen blir på detta sätt liten, enkel och billig och förenklar byggandet av produktionslinjen. De maskinella anordningarna för att styra stängerna 32,34 visas inte. När trycket avlastas och pluggarna 33,36 skjuts inåt av stängerna 32,37 krymper ringarna 30,35 åter elastiskt och enheten 35-39 kan svängas ut till sitt streckade läge visat i figur 1. Formen 19,20 kan nu åter öppnas och rullformningsenheten kan åter skjuta in röret 16 iforrnen och skjuta ut den fonnade produkten ur formen.To pressurize the tube 16 inside the mold 19,20, the rods are mechanically pulled outwards so that the plugs 33,36 reach an initial position where they seal against the rings 30,35 and expand the rings elastically to an initial position with a seal against the tube 16. It is an advantage if the rings expands to seal as it reduces leakage and provides an initial friction against the tube 16, but it is not absolutely necessary. Pressure medium is supplied through the channel 38 and the medium pressure gives the plugs 33,36 a force outwards which influences the rings expanding direction so that they have increased normal force against the tube 16, which has radial support against the mold 19,20. The spokes 29 allow this expansion of the ring 30. In this way you get a self-locking of the end seals and you do not have to apply such a large external axial force to get a seal. In this way, the spirit seal becomes small, simple and cheap and simplifies the construction of the production line. The mechanical devices for guiding the rods 32,34 are not shown. When the pressure is relieved and the plugs 33,36 are pushed inwards by the rods 32,37, the rings 30,35 shrink again elastically and the unit 35-39 can be pivoted out to their dashed position shown in figure 1. The mold 19,20 can now be reopened and the roll forming unit can re-insert the tube 16 into the mold and push the found product out of the mold.
Både pluggarna 33,36 och ringarna 30,35 visas koniska. Det kan dock räcka med att endera ring eller plugg är konisk, men det visade utförandet föredras.Both the plugs 33,36 and the rings 30,35 are shown conically. It may be sufficient, however, that either ring or plug is conical, but the embodiment shown is preferred.
Som tryckmedium kan man på konventionellt sätt använda en suspension av olja i vatten.As a pressure medium, a suspension of oil in water can be used in a conventional manner.
Som förstås ger tillverkningsprocessen enkelt möjlighet till fullständig automatisering från avhaspling av stålband till utmatning av färdig hydrostatiskt formad produkt. 0-1 PC: 'C 0:: *eQ ut CO Både rullformning och hydroformning är var för sig etablerade tekniker och beskrivs därför inte i detalj. Det rullformade röret behöver inte ha cirkulärt tvärsnitt som beskrivits utan kan ha vilket annat tvärsnitt som helst. Det behöver heller inte ha konstant tvärsnitt utmed sin längd förutsatt att tillgänglig rullformningsenhet kan forma sådana rörAs is understood, the manufacturing process easily provides the opportunity for complete automation from unwinding of steel strips to discharge of finished hydrostatically shaped product. 0-1 PC: 'C 0 :: * eQ ut CO Both roll forming and hydroforming are separately established techniques and are therefore not described in detail. The roll-shaped tube does not have to have a circular cross-section as described but can have any other cross-section. It also need not have a constant cross-section along its length provided that the available roll forming unit can form such tubes.
