Description
Oppfinnelsen vedrører en anordning av det slag som er angitt i hovedkravets ingress. The invention relates to a device of the kind stated in the preamble of the main claim.
Det er fra tidligere kjent anordninger hvor endepartiet av et rør presses utad ved plastisk deformasjon slik at det dannes en flens. De kjente anordninger har imidlertid ikke egnet seg for flensing, kraving, e.l. av rør av forskjellig diameter og med forskjellig veggtykkelse ettersom man har manglet nødvendige reguleringsan-ordninger. Som følge av dette har flenseprosessen i mange til-feller gitt et kvalitetsmessig dårlig resultat med bl.a. formfeil i flensen. It is from previously known devices where the end part of a pipe is pressed outwards by plastic deformation so that a flange is formed. However, the known devices have not been suitable for flanging, collaring, etc. of pipes of different diameters and with different wall thicknesses because the necessary regulation devices have been missing. As a result of this, the flange process has in many cases produced a poor quality result with, among other things, shape defects in the flange.
Oppfinnelsens formål er å tilveiebringe en for flensing av rør universelt anvendelig maskin, som har enkel og pålitelig konstruk-sjon og som egner seg for flensing av forskjellig store rør med forskjellig veggtykkelse. The purpose of the invention is to provide a universally applicable machine for flanging pipes, which has a simple and reliable construction and which is suitable for flanging pipes of different sizes with different wall thicknesses.
Oppfinnelsens karakteristiske trekk fremgår av krav 1.. I en anordning ifølge oppfinnelsen er det mulig på en enkel måte å velge flensens krumningsradius ved roten slik at den blir optimal med hensyn til rørets veggtykkelse, hvorved flensing av god kvalitet kan oppnås uavhengig av rørets veggtykkelse. The characteristic features of the invention appear from claim 1. In a device according to the invention, it is possible in a simple way to choose the radius of curvature of the flange at the root so that it becomes optimal with regard to the wall thickness of the pipe, whereby good quality flanges can be achieved regardless of the wall thickness of the pipe.
Den trykkdor som utfører selve flensingen understøttes av en styresleide, som kan lagres forskyvbart på. et par føringsstenger. Reguleringen av trykkdorens stilling i forhold til styresleiden skjer fortrinnsvis med en reguleringsskrue forløpende gjennom trykkdorens stamme. The pressure mandrel that performs the actual flanging is supported by a guide slide, which can be stored displaceably on it. a pair of guide rods. The adjustment of the pressure mandrel's position in relation to the guide slide is preferably done with an adjustment screw running through the pressure mandrel's stem.
Styresleidens forskyvning i forhold til dens opplagring skjer fortrinnsvis ved hjelp av en kraftsylinder.. The displacement of the guide slide in relation to its storage preferably takes place with the help of a power cylinder.
Styresleidens opplagring anordnes i en roterbar enhet, som kan The guide slide's storage is arranged in a rotatable unit, which can
■utgjøres av en ved .den ene ende lagret, stort sett hul sylinder. consists of a mostly hollow cylinder stored at one end.
Anordningen ifølge oppfinnelsen er også forsynt med elementer som pålitelig fastholder og støtter det rør som skal flenses under selve flenseprosessen. The device according to the invention is also provided with elements which reliably retain and support the pipe to be flanged during the flange process itself.
Oppfinnelsen skal beskrives nærmere i det følgende under henvis- The invention shall be described in more detail in the following under reference
ning til vedlagte tegninger, hvorning to the attached drawings, where
fig. 1 viser en prinsippskisse av en flenseanordning ifølge, oppfinnelsen, fig. 1 shows a schematic diagram of a flange device according to the invention,
fig. 2 viser snittet IT-II i fig. 1,fig. 2 shows the section IT-II in fig. 1,
fig. 3 viser trykkdorens innfesting i sin styresleide.fig. 3 shows the fastening of the pressure mandrel in its guide rail.
På tegningene betegner 1 en roterbar sylinder, som via lagerenhet-en 5 er forbundet med en aksel 14 drevet av en hensiktsmessig motor (ikke vist). En trykkdor 8 med et fritt roterende mantel-stykke har sin stammede! 8a forskyvbart lagret på føringer 10 In the drawings, 1 denotes a rotatable cylinder, which via the bearing unit 5 is connected to a shaft 14 driven by a suitable motor (not shown). A pressure mandrel 8 with a freely rotating mantle piece has its stuttered! 8a displaceably stored on guides 10
i én styresleide 7. Trykkdorens stilling i forhold til styresleiden 7 reguleres ved hjelp av en reguleringsskrue 11. Ved omdrei-ning av reguleringsskruen 11 bestemmes radien ved flensens 16 in one guide slide 7. The position of the pressure mandrel in relation to the guide slide 7 is regulated by means of an adjustment screw 11. By turning the adjustment screw 11, the radius at the flange 16 is determined
rot 17.root 17.
Styresleiden 7 er glidbart anordnet mellom to elementer 2 som tjener som opplagring. Forskyvning av styresleiden 7 i forhold til dens opplagring medfører forandring av trykkdorens 8 vinkel-stilling i forhold til det rør 12 som skal flenses. Denne beveg-else styres av styrespor 9 i styresleiden 7 og av tilsvarende styreskinner 13.i opplagringselementene 2. Forskyvning av styresleiden 7 skjer ved hjelp av en kraftsylinder 15. The guide slide 7 is slidably arranged between two elements 2 which serve as storage. Displacement of the guide slide 7 in relation to its support causes a change in the angular position of the pressure mandrel 8 in relation to the pipe 12 to be flanged. This movement is controlled by guide tracks 9 in the guide slide 7 and by corresponding guide rails 13 in the storage elements 2. Displacement of the guide slide 7 takes place with the help of a power cylinder 15.
Trykkdoren 8 med sine stillingsinnstillingsanordninger understøt-tes av sylinderen 1 samt av bjelken 4 og glidestengene 3. Anordningen omfatter også en ledeskrue 6 for forskyvning av trykkdoren 8 i sylinderens 1.radialretning for innstilling av trykkdoren ved flensing av rør av forskjellig diameter.. Opplagringen 2. er så-ledes forskyvbar på glidestengene 3. The pressure mandrel 8 with its position setting devices is supported by the cylinder 1 as well as by the beam 4 and the sliding rods 3. The device also includes a lead screw 6 for displacing the pressure mandrel 8 in the cylinder's 1st radial direction for setting the pressure mandrel when flanging pipes of different diameters.. The storage 2 .is thus displaceable on the slide bars 3.
I fig. 3 er trykkdorens 8 endestilling ved flensingens sluttfase vist med strekede linjer. Trykkdorens 8 vinkelforandringsbeveg-elser og øvrige innstillingsbevegelser er vist med piler.. Rørets 12 innfesting kan utføres på i og for seg kjent måte og er derfor ikke vist 1 detalj, men bare antydet med strekede linjer. pppfinnelsen er ikke begrenset til de viste utførelsesformer, idet flere varianter og modifikasjoner av denne kan tenkes innen-for rammen av de nedenstående patentkrav. In fig. 3, the end position of the pressure mandrel 8 at the end of the flanging phase is shown with dashed lines. The pressure mandrel's 8 angle change movements and other setting movements are shown with arrows. The tube 12 can be attached in a manner known per se and is therefore not shown in detail, but only indicated with dashed lines. The ppp invention is not limited to the embodiments shown, since several variants and modifications of this can be conceived within the scope of the patent claims below.
