Description
Tittel: Drivsylinder for trykkluft eller hydraulisk væske Title: Drive cylinder for compressed air or hydraulic fluid
Ved transportanordninger, heiseinnretninger, kraner og lignende ligger drivsylindrene vanligvis meget trangt. Tilførslen av trykkluft eller hydraulisk væske kan i mange tilfelle ikke finne sted gjennom sylinderbunnen, idet vedkommende tilførselsledninger må føres frem tett langs sylindermantelen og være tilsluttet direkte til denne. Ved stålsylindre påsveises derfor tilkoblingsstykker for dette formål. Den samme konstruktive oppbygning ved aluminium-sylindre fører dette til at det i området ved vedkommende tilslutningsstykke oppstår en materialsyekking på grunn av sveisingen. Nettopp i dette området ved tilkoblingsstykket, opptrer imidlertid på grunn av den oppståtte forandring i veggtykkelsen også bøye-spenninger i tillegg til tangensialspenningene hvilket fører til en høyere påkjenning på det allerede svekkede sted. In the case of transport devices, lifting devices, cranes and the like, the drive cylinders are usually very tight. In many cases, the supply of compressed air or hydraulic fluid cannot take place through the cylinder base, as the supply lines in question must be led closely along the cylinder casing and be connected directly to it. In the case of steel cylinders, connecting pieces are therefore welded on for this purpose. The same constructive structure of aluminum cylinders means that in the area of the connecting piece in question, material shrinkage occurs due to the welding. Precisely in this area at the connection piece, however, due to the resulting change in wall thickness, bending stresses also occur in addition to the tangential stresses, which leads to a higher stress on the already weakened place.
Den .foreslåtte konstruksjon i henhold til oppfinnelsen overvinner den ovenfor nevnte ulempe ved at sylindermantelen og tilkoblingsstykket får tilførsel av trykkluft og/eller hydraulisk væske er ett stykke. Det opptrer da ingen materialsvekking på The proposed construction according to the invention overcomes the above-mentioned disadvantage in that the cylinder jacket and the connecting piece are supplied with compressed air and/or hydraulic fluid in one piece. No material weakening then occurs
grunn av oppheting til sveisetemperatur.due to heating to welding temperature.
Da det ikke foreligger noen sveisesøm, kan tilkoblingsstykket,Since there is no welding seam, the connecting piece,
som forløper parallelt med sylinderaksen, anordnes ganske tett inntil sylindermantelen. which run parallel to the cylinder axis, are arranged quite close to the cylinder casing.
Oppfinnelsesgjenstanden vil nå bli nærmere forklart ved hjelp av et utførelseseksempel og under henvisning til den vedføyde tegning, hvorpå: The object of the invention will now be explained in more detail by means of an embodiment and with reference to the attached drawing, whereupon:
Fig. 1 viser en hel drivsylinder i lengdesnittFig. 1 shows a complete drive cylinder in longitudinal section
Fig. 2 viser en utskåret del av drivsylinderenFig. 2 shows a cut-out part of the drive cylinder
Fig. 3 og 4 viser forskjellige tverrsnitt av drivsylinderen.Fig. 3 and 4 show different cross-sections of the drive cylinder.
Som det vil fremgå av fig. 1, viser denne figur en hydraulisk sylinder som består av en sylindermantel 1 som er utført i et stykke med et koblingsstykke 2 ved hjelp av en ekstruderings-prosess med etterfølgende sponfraskillende fjerning av grader og overflødige deler, hvoretter løpeflatene hårdanodiseres. Sylinderstemplet 3 og den hydrauliske tilslutning 5 er utført på kjent måte for regulering av tilbakestrømningen av den hydrauliske væske er det i koblingsstykket 2 for eksempel inne-bygget en tilbakeslagsventil 6 av kuletype samt en drossel-boring 7. Fig. 2 viser tilkoblingsområdet for den hydrauliske væsketil-førsel, og det vil også av denne figur fremgå at tilkoblingsstykket 2 og sylindermantelen 1 er utført i ett stykke. Fig. 3 viser et ekstrudert tverrsnitt som hovedsakelig består av sylindermantel 1 og en samtidig ekstrudert koblingsdel 2. Fig. 4 viser tverrsnittet av en ekstruderingsprofil bestående av to sammensatte sirkelringer, hvorav den ene utgjør sylindermantelen 1 og den annen tilkoblingsstykket 2 med en utboring 4. As will be seen from fig. 1, this figure shows a hydraulic cylinder consisting of a cylinder jacket 1 which is made in one piece with a coupling piece 2 by means of an extrusion process with subsequent chip-separating removal of burrs and redundant parts, after which the running surfaces are hard anodized. The cylinder piston 3 and the hydraulic connection 5 are made in a known manner for regulating the return flow of the hydraulic fluid, the coupling piece 2 for example has a ball-type non-return valve 6 and a throttle bore 7 built into it. Fig. 2 shows the connection area for the hydraulic liquid supply, and it will also appear from this figure that the connecting piece 2 and the cylinder jacket 1 are made in one piece. Fig. 3 shows an extruded cross-section which mainly consists of cylinder casing 1 and a simultaneously extruded connecting part 2. Fig. 4 shows the cross-section of an extrusion profile consisting of two composite circular rings, one of which forms the cylinder casing 1 and the other the connecting piece 2 with a bore 4.
Oppfinnelsens grunnleggende ide er bare eksempelvis anskuelig-gjort i de vedføyde figurer, og er på ingen måte begrenset til de viste utførelser. Tilkoblingsstykket kan således for eksempel også oppvise rektangulært tverrsnitt. The basic idea of the invention is only illustrated by way of example in the attached figures, and is in no way limited to the embodiments shown. The connecting piece can thus, for example, also have a rectangular cross-section.
