Description
Anordning for renfresning av flater på masseblokker av lettbetong eller lignende. Device for cleaning surfaces on mass blocks of lightweight concrete or similar.
Det er tidligere kjent en trådfres beregnet for i kombinasjon med en transportskrue å frese bort og fjerne overskuddmateriale som oppstår ved stopning av den råblanding som anvendes ved fremstill-ing av lettbetong. Trådfresen består av et antall på en aksel på hensiktsmessig innbyrdes avstand festede sirkulære stbtteskiver. pe to ytre stbtteskiver er kraftig dimensjonert, slik at skjæretrådene kan spenne over dem. De indre stbtteskiver tjener til jjnderstbttelse av trådene og hindring av at disse kan forandre fetilling. Skjæretrådene er fast innspent til den ene ytre stbtte-£kives nav og lbper over uttak i skivens periferi over til den andre endeskive, hvor de er forsynt med fjærer og over en stramme-anordning er festet til stotteskivens nav. It is previously known a wire cutter intended for, in combination with a transport screw, to mill away and remove excess material that occurs when stuffing the raw mixture used in the production of lightweight concrete. The wire cutter consists of a number of circular support discs attached to an axle at an appropriate distance from each other. The two outer support discs are heavily dimensioned so that the cutting wires can span over them. The inner support discs serve to support the threads and prevent them from changing their threading. The cutting wires are firmly clamped to the hub of one outer support disc and pass over outlets in the periphery of the disc to the other end disc, where they are provided with springs and are attached to the hub of the support disc via a tensioning device.
Selv om den beskrevne anordning har vist seg å gi gode resultater i forhold til andre kjente anordninger med samme formål, så har den imidlertid i en viss utstrekning vært forenet med uonskede mangler. Således har av og til trådbrudd forekommet, hvilke dels bevirker at den del av masseblokken som for anledningen er i kon-takt med trådfresen må kasseres, dels at et mer eller mindre lang-varig driftsavbrudd oppstår i den tid det tar å fjerne den brustne tråd samt anbringe en ny tråd. Gjentaes slike trådbrudd ofte, er det innlysende at anordningen ikke med fordel kan anvendes i en produksjonskjede, hvor hvert arbeidstrinn har til disposisjon en forutbestemt tid. Although the described device has been shown to give good results in relation to other known devices with the same purpose, it has, however, to a certain extent been associated with undesirable defects. Thus, wire breaks have occasionally occurred, which partly causes the part of the mass block that is in contact with the wire cutter to be discarded, and partly causes a more or less long-term interruption of operation during the time it takes to remove the broken wire and place a new thread. If such thread breaks are repeated frequently, it is obvious that the device cannot be used with advantage in a production chain, where each work step has a predetermined time at its disposal.
Det er nu foreslått en like overraskende som konstruktiv enkel freseanordning, hvorved nevnte ulemper helt er eliminert. Anordningen kjennetegnes nærmest ved at hver enkelt skjæretråd er anordnet for å lope i en ubrutt linje over en av to stotteskiver dannet seksjon samt over inntil liggende seksjon er anordnet trukket inn mot akselen. A milling device that is as surprising as it is constructively simple has now been proposed, whereby the aforementioned disadvantages are completely eliminated. The device is best characterized by the fact that each individual cutting wire is arranged to run in an unbroken line over a section formed by two support discs and over until the horizontal section is arranged drawn in towards the axle.
Under henvisning til tegningen folger nedenfor en nærmere beskriv-else av en utforelsesform av anordningen ifolge oppfinnelsen. På tegningen er: With reference to the drawing, a detailed description of an embodiment of the device according to the invention follows below. In the drawing are:
Fig. 1 en horisontalprojeksjon av freseanordningen , Fig. 1 a horizontal projection of the milling device,
Fig. 2 freseanordningen sett fra siden, Fig. 2 the milling device seen from the side,
Fig. 3 et snitt A - A i fig. 1. Fig. 3 a section A - A in fig. 1.
Fig. 1 viser en trådfres 10, bestående av en aksel 11, på hvilkea på lik avstand fra hverandre er festet sirkulære stotteskiver 12,'som inndeler akselen i seksjoner 13 - 17. Over stotteskivene er<;>spent skjæretråder 18 - 22, som er fast innspent i det ene nav 23<*>Fig. 1 shows a wire cutter 10, consisting of a shaft 11, on which circular support disks 12 are attached at equal distances from each other, which divide the shaft into sections 13 - 17. Cutting wires 18 - 22 are stretched over the support disks, which is firmly clamped in one hub 23<*>
i sarnt i det andre nav 24 er innspent via fjærer 25. I motsetning til den tidligere kjente trådfres, hvor skjæretrådene utspennes i similarly, the second hub 24 is clamped via springs 25. In contrast to the previously known wire cutter, where the cutting wires are tensioned in
en ubrutt linje fra endeskive til endeskive, er hver enkelt tråd foreslått forlopende i ubrutt linje over en av to stotteskiver dannet seksjon samt over inntil liggende seksjon er trukket inn mot akselen. an unbroken line from end disc to end disc, each individual thread is proposed to run in an unbroken line over one of the sections formed by two support discs and over until the horizontal section is drawn in towards the axle.
Inntrekningen av tråden mot akselen er utfort ved hjelp av sirkulære festeskiver 26, som er festet midt imellom stotteskivene. The drawing in of the thread towards the axle is carried out by means of circular fixing discs 26, which are fixed in the middle between the support discs.
På festeskivenes periferi er det anbragt kroker 27 for trådene. Disse kroker er da anbragt på festeskivene med samme delning som forekommer for trådenes innfestning til navene. Skjæretrådene er innbyrdes avvekslende trukket inn resp. rett utspente, dvs. en tråd 18 forlbper i ubrutt linje over seksjonen 13 og er trukket inn mot akselen i seksjonen 14, mens nabotråden 19 er trukket inn i seksjonen 13 og rett utspent over seksjonen 14. Derved får planfresens mantelflate en jevn fordeling av de aktivt skjærende trådpartier. Hooks 27 for the threads are placed on the periphery of the fixing discs. These hooks are then placed on the fastening discs with the same division as occurs for the fastening of the threads to the hubs. The cutting threads are alternately pulled in resp. straight out, i.e. a wire 18 continues in an unbroken line over the section 13 and is drawn in towards the shaft in the section 14, while the neighboring wire 19 is drawn into the section 13 and straight out over the section 14. Thereby the surface of the face mill gets an even distribution of the actively cutting wire sections.
Ved fresning med den beskrevne planfres blir den bearbeidede flate av masseblokken helt plan samt fremviser helt åpne porer. When milling with the described planer, the machined surface of the pulp block becomes completely flat and exhibits completely open pores.
Grunnen til det gode resultat synes å være at trådene ved en planfres ifblge oppfinnelsen vil bli liggende ubevegelige mot stotteskivene. Ved den tidligere kjente freseanordning var trådene utspent over.hele fresens lengde. Ved fresning kom trådene av massens trykk i skjærebyeblikket til å heves med buen vendt i masseblokkens transportretning. Efter avsluttet skjæring gikk tråden tilbake til sin opprinnelige stilling. Dette betydde at tråden for hver omdreining fikk en mot stotteskivene glidende bevegelse, hvilket bevirket at skjæretrådene ble slitt og efter en viss tid brast. The reason for the good result seems to be that the threads of a planer according to the invention will lie motionless against the support discs. With the previously known milling device, the threads were stretched over the entire length of the milling cutter. When milling, the threads were raised by the pressure of the mass at the time of cutting with the arc facing the direction of transport of the mass block. After finishing cutting, the thread returned to its original position. This meant that for each revolution the thread got a sliding movement against the support discs, which caused the cutting threads to wear and after a certain time burst.
Ved å anordne trådene ifblge foreliggende oppfinnelse, unngåes!nevnte boyning av trådene og disse vil ved fresning ligge uror-.lige i forhold til stotteskivene. By arranging the threads in accordance with the present invention, the above-mentioned bowing of the threads is avoided and these will lie unmoved in relation to the support discs during milling.
Anordningen ifblge oppfinnelsen er ikke begrenset til den påjtegningen viste utfbrelsesform. Således kan skjæretrådene være The device according to the invention is not limited to the embodiment shown in the drawing. Thus the cutting threads can be
