Abstract

An arrangement of cutters (4) and spacers (5) are fitted on a pair of shafts (2,3) for cutting the required number and widths of material strips. The shafts are supported by two frame portions (6,7) and driven through a reduction gear box (8) by a motor (1). One frame (7) is movable in the axial direction of the shafts and also transversely, on a two-directional sliding track arrangement (13-17) to allow removal and rearrangement of cutters and discs. The shaft support trust rings (20) are axially movable by hydraulic pressure by piston and cylinder systems incorporated in the end frame (7) and supplied by hydraulic lines (34).

NÄRMARE BESKRIVNING AV UPPFINNINGEN: Som ovan nämnts användes ett skärverk där slittningen sker mellan två skärstålsaxlar ,1, som är utrustade med skärstål ,2, och mellanliggande distansringar ,3. Distansringarnas ,3, bredd bestäm- mes av bredden hos de slitsade banden. Satsen av distansringar ,3, och skärstål ,2, fasthålles mellan en fast ring ,4, och en rörlig hydraulisk klämring ,5, på skärstålsaxeln ,1. Den fasta ringen ,4, är placerad alldeles innanför lagringen ,6, vid den axelända ,7, där drivanordningen ,8, (här antydd med ett kugg-hjul) är belägen.DETAILED DESCRIPTION OF THE INVENTION: As mentioned above, a cutting machine was used where the wear takes place between two cutting steel shafts, 1, equipped with cutting steel, 2, and intermediate spacer rings, 3. The width of the spacer rings, 3, is mes of the width of the slotted bands. The set of spacer rings, 3, and cutting steel, 2, is held between a fixed ring, 4, and a movable one hydraulic clamping ring, 5, on the cutting shaft, 1. The fixed ring, 4, is located just inside the bearing, 6, at the shaft end, 7, where the drive device, 8, (here indicated by a gear wheel) is located.

Den hydrauliska klämringen ,5, vid den andra änden av skärståls- axeln ,1, är axiellt förskjutbar.The hydraulic clamping ring, 5, at the other end of the cutting steel the shaft, 1, is axially displaceable.

Klämringen ,S, kan liknas vid cylindern till en domkraft som hydrauliskt kan flyttas i axiell led i förhållande till sin inuti löpande kolv ,12. Kolven ,12, utgör en del av en inemot skärståls- axelns mitt vänd krage ,13, hos en i övrigt i stort sett cylind- risk hylsa ,10, som är trädd på skärstålsaxens ,1, ände.The clamping ring, S, can be likened to the cylinder of a jack that hydraulically can be moved in the axial direction relative to its inside continuous piston, 12. The piston, 12, forms part of an inwardly the center-facing collar, 13, of an otherwise substantially cylindrical risk sleeve, 10, which is threaded on the end of the cutting steel shear, 1.

På hylsans ,10, yttre mantelytan är monterat rullningslager ,15. Rullningslagren,15, är via lagerhus ,6, förbundna med den ena utsvängbara gaveln hos skärverket. Mellan hylsan ,10, och skär- stålsaxelns ,1, cylindriska axeltapp ,11, är monterad en hålaxel ,9, d.v.s en hylsa med gavel ,17, i ena änden. Hålaxelns ,9, inner- diameter är svarvud med glidpassning mot skärstålsaxelns ,1, axel- tapp 11. Dess yttermantel är något inåtkonad mot dess gavel ,17.A roller bearing is mounted on the outer mantle surface of the sleeve 10 , 15. The rolling bearings, 15, are connected to one via bearing housings, 6 pivoting end of the cutting unit. Between the sleeve, 10, and the cutting of the steel shaft, 1, cylindrical shaft pin, 11, is mounted a hollow shaft , 9, i.e. a sleeve with end, 17, at one end. Hollow shaft, 9, inner- diameter is a turning head with a sliding fit against the cutting steel shaft, 1, shaft pin 11. Its outer mantle is slightly inwardly conical towards its end, 17.

Cylindriska hylsans ,10, inneryta är anpassad för anliggning mot yttermanteln hos hålaxeln ,9, så att det medges en viss uppdrivning av hylsan ,10, på hålaxeln ,9. Uppdrivningen åstadkommes genom an- bringande av en kraft mot dess ände axiellt riktad in mot skär- stålsaxelns ,1, mitt. Denna kraft åstadkommes av en hydraulcylinder ,18, vars kolv ,19, utgör en del av hålringens ,9, gavel,17. Med hjälp av hydraulcylindern ,18, skapas en kraft mot hylsans ände.The inner surface of the cylindrical sleeve, 10, is adapted for abutment the outer shell of the hollow shaft, 9, so as to allow some traction of the sleeve, 10, on the hollow shaft, 9. The uplift is achieved by using bringing a force towards its end axially directed towards the cutting steel shaft, 1, middle. This force is provided by a hydraulic cylinder , 18, whose piston, 19, forms part of the hollow ring, 9, end, 17. With by means of the hydraulic cylinder, 18, a force is created towards the end of the sleeve.

Genom lämpligt avpassad konicitet hos anliggningen mellan hålaxel ,9, och hylsa ,10, kan hylsan ,1@, då drivas axiellt upp på hål- axeln ,9, tills rörelsen avbryts av hydraulcylinderns ,18, i förväg avpassade slaglängd. Därvid skapas erfoderlig fashållande kraft mellan axeltapp ,11, och hylsan ,10, via hålringen ,9, samtidigt som lagringens plats på axeltappen ,11, alltid blir lika.By suitably adapted conicity of the bearing between the hollow shaft , 9, and sleeve, 10, the sleeve, 1 @, can then be driven axially up on the hole. the shaft, 9, until the movement is stopped by the hydraulic cylinder, 18, in advance adapted stroke. This creates the required holding force between the shaft pin, 11, and the sleeve, 10, via the hollow ring, 9, simultaneously as the bearing location on the shaft journal, 11, always becomes equal.

Inåt från hylsans ,10, gavel är borrat tre hål ,21-23. Det första hålet ,21, leder till klämringen ,5. Till detta borrhål ,21, är även ansluten en fjäderbelastad accumulator för att för- hindra tryckfall vid eventuellt läckage. Det andra hålet ,22, leder fram till ringformiga ursparingar ,26, i hylsans ,1ß, inre mantel- yta. Det tredje borrhålet ,23, anslutes till hydraulcylindern ,18, som är placerad vid gaveln ,17, på hålaxeln ,9. Alla tre borrhålen 10 15 20 25 30 35 40 45 50 505 702 3 ,21-23, år anslutna var för sig till en runt skärstålsaxeln ,1, vridbar tryckoljeanslutning ,24, dit tryckolja ledes från en tryck- oljepump (ej visad) via flexibla slangar ,27.Inwardly from the sleeve, 10, end, three holes are drilled, 21-23. The the first hole, 21, leads to the clamping ring, 5. To this borehole , 21, a spring-loaded accumulator is also connected to prevent pressure drop in the event of a leak. The second hole, 22, leads up to annular recesses, 26, in the sleeve, 1ß, inner jacket surface. The third bore, 23, is connected to the hydraulic cylinder, 18, which is located at the end, 17, on the hollow shaft, 9. All three boreholes 10 15 20 25 30 35 40 45 50 505 702 3 , 21-23, years connected separately to one around the cutting steel shaft, 1, rotatable pressure oil connection, 24, to which pressure oil is led from a oil pump (not shown) via flexible hoses, 27.

Vid byte av uppsättning av skärstål ,2, och distansringar ,3, förfares lämpligast på följande sätt: 1. Trycket i rörsystemet till klåmringen ,5, avlastas till nolltryck så att paketet inte längre spännes ihop mot den fasta ringen ,4. 2. Oljetrycket till hydraulcylindern höjes för fortsatt lås- ning av hylsans ,1ß, läge i förhållande till axeltappen ,11. 3. Ojetrycket till ursparingarna höjes så att en oljefilm bildas mellan hålaxelns ,9, yttre och hylsans ,10, inre mantelyta. 4. Oljetrycket i hydraulcylindern ,18, avlastas succesivt.When changing set of cutting steel, 2, and spacer rings, 3, is most conveniently carried out as follows: 1. The pressure in the pipe system of the clamping ring, 5, is relieved to zero pressure so that the package is no longer clamped against the fixed one rings, 4. 2. The oil pressure of the hydraulic cylinder is increased for continued locking of the sleeve, 1ß, position in relation to the shaft journal, 11. 3. The eye pressure of the recesses is raised so that an oil film formed between the hollow shaft, 9, outer and sleeve, 10, inner shell surface. 4. The oil pressure in the hydraulic cylinder, 18, is gradually relieved.

Därvid glider hylsan ,10, sakta utåt på hålaxeln ,9, tills den lossnar och skärmaskinens gavel med tillhörande lagerhus ,6, kan svängas bort. Därmed kan paketet med distansringar ,3, och skärstål ,2, avdragas från från skärstålsaxeln ,1, och ett nytt paket påfö- ras. 5. Skärmaskinens gavel svänges åter på plats. Därvid föres hålaxeln ,9, fram mot anslaget ,20. 6. Oljetrycket vid ursparingarna ,26, höjes så att olja spri- des över anliggningsytorna mellan hålaxel ,9, och hylsa ,10. 7. Oljetrycket höjes i hydraulcylindern ,18, och hylsan drives upp på hålaxeln så långt som hydraulcylinderns ,18, slag- längd tillåter. 8. Oljetrycket i systemet vid ursparingarna ,Z6, avlastas.In this case, the sleeve, 10, slides slowly outwards on the hollow shaft, 9, until it loosens and the end of the cutting machine with associated bearing housing, 6, can swung away. Thus, the package can with spacer rings, 3, and cutting steel , 2, is deducted from the cutting steel shaft, 1, and a new package is applied. race. 5. Swivel the end of the cutting machine back into place. Thereby brought hollow shaft, 9, towards the stop, 20. 6. The oil pressure at the recesses, 26, is raised so that the oil was mounted over the abutment surfaces between the hollow shaft, 9, and the sleeve, 10. 7. The oil pressure is raised in the hydraulic cylinder, 18, and the sleeve driven up on the hollow shaft as far as the stroke of the hydraulic cylinder, 18, length allows. 8. The oil pressure in the system at the recesses, Z6, is relieved.

Därvid erhålles ett fast grepp mellan hylsan ,1@, och axeltappen ,11, via hålaxeln ,9, och bandskärningen kan åter påbörjas.Thereby a firm grip is obtained between the sleeve, 1 @, and the shaft pin , 11, via the hollow shaft, 9, and strip cutting can be resumed.

Allt detta kan skötas på avstånd från en manöverpulpet efter ett mer eller mindre automatiserat rörelsechema.All this can be handled at a distance from one control panel after another more or less automated movement schedule.
