Description
504 187, 2 typ, samt vilket även under en uppstartningsfas medför att de varandra närliggande sågklingorna löper i ett relativt varandra parallellt förhållande, utan uppkomst av de ovan berörda svängningsrörelserna relativt varandra. Uppfinningen avser även en anordning för utövande av sättet. 504 187, 2 type, and which even during a start-up phase means that they adjacent saw blades run in a relative to each other parallel relationship, without the emergence of the above the oscillating movements relative to each other. The invention also relates to a device for practicing the method.
Sättet enligt föreliggande uppfinning för att förhindra eller reducera uppkomst av magnetism i två relativt varandra närliggan- de och motroterande sågklingor kännetecknas i huvudsak av att varje sågklinga utformas med ett antal väsentligen radiellt utsträckta genomgående spår med en utsträckning inom området mellan varje sågklingas rotationscentrum och det omgivande sågtandformiga området, utformade att vid rotation avleda luft förefintlig mellan sågklingornas varandra närliggande plan, samt att därvid förhindra eller reducera magnetisering av sågk- lingorna.The method of the present invention for preventing or reduce the occurrence of magnetism in two relatively close they and counter-rotating saw blades are mainly characterized by that each saw blade is formed with a number substantially radially extended continuous tracks with an extension within the area between the center of rotation of each saw blade and the surrounding sawtooth-shaped area, designed to divert air during rotation present between the adjacent planes of the saw blades, and thereby preventing or reducing magnetization of the saw lingorna.
Anordningen för utövande av sättet enligt föreliggande uppfinning kännetecknas i huvudsak av att varje sågklinga är utformad med ett antal väsentligen radiellt utsträckta genomgående spår med en utsträckning inom området mellan varje sågklingas rotations- centrum och det omgivande sågtandformiga området, utformade att vid rotation avleda luft förefintlig mellan sågklingornas varandra närliggande plan.The apparatus for practicing the method of the present invention is mainly characterized by the fact that each saw blade is designed with a number of substantially radially extending through grooves with an extent within the range between the rotation of each saw blade center and the surrounding sawtooth-shaped area, designed to when rotating, divert air present between the saw blades adjacent planes.
Sättet enligt föreliggande uppfinning samt icke begränsande exempel på en anordning för utövande av sättet skall nedan närmare beskrivas med hänvisning till de bifogade ritningarna, varpåz- Fig. 1 visar en sidovy av en en sågklinga ingående i ett samverkande sågklingepar, betraktad från den sida som är närliggande samverkande sågklinga samt utformad med ett utför- ingsexempel på en anordning enligt uppfinningen; Fig. 2 visar en vy i tvärsektion i förstorad skala vid snittlin- jen II - II i Fig. 1; samt 504 187 3 Fig. 3 visar en vy motsvarande Fig. 2 utvisande två relativt varandra motroterande samt samverkande sågklingor.The method of the present invention and non-limiting examples of a device for practicing the method shall be given below described in more detail with reference to the accompanying drawings, varpåz- Fig. 1 shows a side view of a saw blade included in one cooperating saw blade pairs, viewed from the side that is adjacent cooperating saw blade and designed with a examples of a device according to the invention; Fig. 2 shows a cross-sectional view on an enlarged scale at section line. and II - II in Fig. 1; and 504 187 3 Fig. 3 shows a view corresponding to Fig. 2 showing two relative counter-rotating and cooperating saw blades.
Problemet med en kraftig magnetisering av två närliggande och motroterande sågklingor torde sammanhänga med en jonisering av mellanliggande luftmolekyler i förening med uppkomst av ett magnetiskt/elektriskt växelfält, och detta fenomen påverkar också sågklingorna under ett initialt uppstartningsskede, samt skapar härvid de icke önskade svängningarna vid sågklingorna, vilka medför att sågklingorna icke löper i ett parallellt förhållande till varandra.The problem of a strong magnetization of two adjacent and counter-rotating saw blades should be related to an ionization of intermediate air molecules in association with the formation of a magnetic / electric alternating field, and this phenomenon also affects the saw blades during an initial start-up stage, and creates in this case the undesired oscillations at the saw blades, which means that the saw blades do not run in a parallel relationship to eachother.
Vid tidigare kända lösningar har, såsom omnämnts tidigare, sågklingorna förutsatts stabiliserade relativt.varandra genonnatt t.ex. luftkanaler utformas i sågklingorna, vilka vid desammas rotation tillför luft till området mellan sågklingorna, samt således genom ett pneumatiskt tryck stabiliserar desamma under en sågoperation.In previously known solutions, as mentioned earlier, the saw blades are assumed to be stabilized relative to each other overnight for example air ducts are formed in the saw blades, which at the same time rotation supplies air to the area between the saw blades, and thus by a pneumatic pressure stabilizes them under a sawing operation.
Sättet enligt föreliggande uppfinning baserar sig på en väsentlig och i sammanhanget förvånande förändring av tidigare accepterad teknik, nämligen att med företrädesvis väsentligen radiellt utsträckta genomgående spårformiga urtagningar i området mellan sågklingornas centrumparti och sågtandsområdet avleda luft förefintlig mellan sågklingorna.The method of the present invention is based on an essential and in this context surprising change of previously accepted technique, namely that with preferably substantially radially extended through groove-shaped recesses in the area between the center portion of the saw blades and the sawtooth area divert air present between the saw blades.
Rent 'teoretiskt, så borde en sådan åtgärd. medföra att såg- klingorna sammanpressades mot varandra, samt troligtvis att desamma ytterligare skulle magnetiseras, t.ex. genom friktionspå- verkan.Purely 'theoretically, such a measure should. cause to saw- the blades were compressed against each other, and probably that the same would be further magnetized, e.g. by frictional effect.
Sättet enligt föreliggande uppfinning medför dock en förvånande effekt, dels undvikes magnetisering av sågklingorna (i allt väsentligt), dels erhåller sågklingorna en jämn och parallell gång redan vid uppstart av rotation i motsatta rotationsrikt- ningar. Som en ytterligare förvånande effekt vidmakthåller sågklingorna ett varandra närliggande, men separerat, för- 504 187 hållande.However, the method of the present invention is surprising effect, and magnetization of the saw blades is avoided (in all significantly), partly the saw blades get a smooth and parallel already at the start of rotation in opposite directions of rotation nings. As an additional surprising effect persists the saw blades an adjacent, but separated, 504 187 holding.
Med hänvisning till Fig. 1 så visas ett exempel på en utförings- form för utnyttjande av sättet enligt föreliggande uppfinning.Referring to Fig. 1, an example of an embodiment is shown. form for utilizing the method of the present invention.
En sågklinga, såsom helhet betecknad 1, är utformad med ett antal väsentligen, radiellt utsträckta genomgående spår 2, 2', 2", företrädesvis huvudsakligen vinkelmässigt likformigt skilda från varandra. I det visade utföringsexemplet uppvisa spåren 2, 2', 2" en något böjd kurvformig utsträckning, med respektive ändparti lokaliserade såsom inledande första partier i rotationsriktningen för sågklingan 1, samt med det centrala partiet såsom ett efterföljande parti. Denna konfiguration utgör en föredragen konfiguration, med även en omvänd utsträckning, eller väsentligen linjär utsträckning, kan även utnyttjas.A saw blade, as a whole designated 1, is formed with a number substantially, radially extending through grooves 2, 2 ', 2 ", preferably substantially angularly uniformly distinct from each other. In the embodiment shown, the grooves 2, 2 ', 2 "a slightly curved curved extension, with the respective end portion located as initial first portions in the direction of rotation for the saw blade 1, and with the central portion as one subsequent party. This configuration is a preferred one configuration, with even a reverse extent, or substantially linear extent, can also be used.
Effekten av dessa spår kan ytterligare förstärkas, vilket inledningsvis kommer att beskrivas med hänvisning till Fig. 2.The effect of these tracks can be further enhanced, which will initially be described with reference to Fig. 2.
I syfte att ytterligare klargöra vilket plan som är närliggande en samverkande sågklinga 1', så har detta betecknats “N“, medan det plan som vid användning utgör ett yttre eller utvändigt plan betecknats "U". Här visas ett spår 2 i tvärsektion, varav framgår att spåren 2, 2', 2" uppvisa en avfasning 3 vid det kantparti som utgör ett inledande kantparti i rotationsriktningen, samt att spårens 2, 2', 2" avslutande kantparti i rotationsriktningen uppvisa en avfasning 4 utsträckt i samma riktning. Sistnämnda avfasning 4 utgår härvid från det inre sidoplanet och lutar i riktning mot det yttre sidoplanet, medan den första avfasningen 3 avslutas i anslutning till det kantparti av spåren 2, 2', 2" som är lokaliserat vid sågklingans 1 yttre plan.In order to further clarify which plan is nearby a cooperating saw blade 1 ', this has been designated "N", while the plane which, in use, constitutes an external or external plane designated "U". Here, a track 2 is shown in cross section, from which it appears that the grooves 2, 2 ', 2 "have a chamfer 3 at the edge portion which constitutes an initial edge portion in the direction of rotation, and that the closing edge portion of the grooves 2, 2 ', 2 "in the direction of rotation exhibit a chamfer 4 extending in the same direction. The latter bevel 4 then starts from the inner side plane and slopes in direction to the outer side plane, while the first bevel 3 terminates adjacent to the edge portion of the grooves 2, 2 ', 2 " which is located at the outer plane of the saw blade 1.
Dessa avfasningar 3, 4 åstadkommer vid sågklingans 1 rotation en avledning av luft förefintlig vid sågklingans 1 inre plan, d.v.s. det plan som är närliggande en samverkande sågklinga 1'.These chamfers 3, 4 produce one at the rotation of the saw blade 1 diversion of air present at the inner plane of the saw blade 1, i.e. the plane adjacent to a cooperating saw blade 1 '.
Detta framgår mera i detalj av Fig. 3, vilken visar ett parti av två relativt varandra motroterande sågklingor 1, 1' i ett närliggande förhållande. Denna figur illustrerar hur spåren 2, 504 187 5 2', 2" under sågklingornas 1, 1' rotation avleder därimellan förefintlig luft, en åtgärd som medför att magnetisering av sågklingorna 1, 1' undvikes, varjämte sågklingorna 1, 1' bibringas en lugn och parallell gång under den inledande delen av en sågoperation. Tidigare redovisade avfasningar 3, 4 medför härvid att en förstärkt luftavledning åstadkommes, men även utan sådana avfasningar erhålles en acceptabel reducering av såg- klingornas 1, 1' magnetisering.This is shown in more detail in Fig. 3, which shows a portion of two relatively counter-rotating saw blades 1, 1 'in one close relationship. This figure illustrates how the grooves 2, 504 187 5 2 ', 2 "during the rotation of the saw blades 1, 1' diverts therebetween existing air, a measure that causes magnetization of the saw blades 1, 1 'are avoided, and the saw blades 1, 1' is given a calm and parallel gait during the introductory part of a sawing operation. Previously reported phases 3, 4 entail in this case that a reinforced air diversion is achieved, but also without such chamfers, an acceptable reduction in sawdust is obtained. the magnetization of the blades 1, 1 '.
Som ett exempel på en föredragen utföringsform så utformas fem spår 2, 2', 2" med en spårbredd på 3 mm, samt med avfasningar 3, 4 utformade med en vinkel på 45°. Ett sågklingepar (diameter 225 mm) med ett sådant utförande har inom varvtalsområdet 2.000 - 4.700 v/min icke medfört magnetisering av sågklingorna 1, 1'.As an example of a preferred embodiment, five are designed grooves 2, 2 ', 2 "with a groove width of 3 mm, and with chamfers 3, 4 designed with an angle of 45 °. A pair of saw blades (diameter 225 mm) with such a design has within the speed range 2,000 - 4,700 rpm did not result in magnetization of the saw blades 1, 1 '.
Prov har även genomförts utan avfasningar 3, 4, och vid ett varvtal av 2.000 v/min medförde en spårbredd för spåren 2, 2', 2" på minst 4,8 mm att magnetisering förhindrades. Vid en ökning av varvtalet till 4.700 v/min krävdes en spårbredd på minst 6 mm för att magnetisering skulle undvikas, d.v.s. en ökad spårbredd erfordras vid ett förhöjt varvtal.Tests have also been performed without chamfers 3, 4, and at one speed of 2,000 rpm resulted in a track width for tracks 2, 2 ', 2 "of at least 4.8 mm that magnetization was prevented. At an increase of the speed to 4,700 rpm, a track width of at least 6 mm was required in order to avoid magnetization, i.e. an increased track width required at an increased speed.
Det är även möjligt att reducera spårbredden under 3 mm genom en förändring av avfasningarnas 3, 4 vinkel. Härvid utföres avfasningarna 3, 4 med en spetsigare vinkel, reducerad med cza 3°för varje millimeters reducering av spårbredden, d.v.s. c:a 42' vid en spårbredd på 2 mm, samt c:a 39° vid en spårbredd på 1 mm.It is also possible to reduce the groove width below 3 mm by one change in the angle of the bevels 3, 4. Hereby performed the chamfers 3, 4 with a sharper angle, reduced by cza 3 ° for each millimeter reduction of the track width, i.e. 42 ' at a groove width of 2 mm, and approx. 39 ° at a groove width of 1 mm.
Avfasningar med en trubbigare vinkel än 45° ger ett avsevärt sämre resultat, samt innebär att spårens 2, 2', 2" bredd inte kan reduceras på beskrivet sätt.Chamfers with an obtuse angle of more than 45 ° give a considerable poorer results, and means that the width of the grooves 2, 2 ', 2 "can not reduced as described.
Av ovan beskrivna exempel på olika utföringsformer framgår, att flera variabler föreligger med avseende på spårens 2, 2', 2" utformning, vilka kan varieras för erhållande av avsett resultat.From the above-described examples of different embodiments it appears that several variables exist with respect to tracks 2, 2 ', 2 " design, which can be varied to obtain the intended result.
Utöver vad som exemplifierats, så utgör givetvis spårantalet en ytterligare variabel, varvid exemplifierade utföringsformer innefatta fem spår 2, 2', 2", väsentligen likformigt skilda från 504 187 6 varandra med en vinkel i storleksordningen 72°. En reducering eller ökning av antalet spår 2, 2', 2" kan således kompenseras genom en ökning/minskning av spårens 2, 2', 2" bredd, varjämte spårbredden ytterligare kan minskas genom tidigare berörda avfasningar. Även utnyttjat varvtal har en viss påverkan på spårbredden, speciellt i de fall där spårens 2, 2', 2" kant- partier icke utformas med avfasningar, vilket som tidigare redovisat medför ett behov av en större spårbredd vid högre varvtal.In addition to what has been exemplified, the number of tracks is of course one further variable, with exemplary embodiments comprise five grooves 2, 2 ', 2 ", substantially uniformly separated from 504 187 6 each other at an angle of the order of 72 °. A reduction or increase in the number of grooves 2, 2 ', 2 "can thus be compensated by an increase / decrease in the width of the grooves 2, 2 ', 2 ", respectively the track width can be further reduced by previously affected chamfers. Utilized speed also has a certain effect on the track width, especially in cases where the 2, 2 ', 2 "edge lots are not designed with chamfers, as before reported entails a need for a larger track width at higher speed.
De utföringsformer som ovan berörts utgör givetvis enbart icke begränsande exempel på utföringsformer för utövande av sättet enligt föreliggande uppfinning, då uppenbarligen ytterligare modifieringar kan utföras med utgångspunkt från de variabler som angivits ovan för anpassning till varje sågklingas diameter och arbetsvarvtal, i syfte att erhålla eftersträvad parallell och jämn rörelse under en uppstartningsfas, samt för att väsentligen fullständigt förhindra uppkomst av magnetism i sågklingorna under dessas relativt varandra motroterande rörelse. Uppfinningen är således på intet sätt begränsad till tidigare exemplifierade utföringsexempel, vilka endast avse att tjäna som exempel för att underlätta.förståelsen för sättet enligt föreliggande uppfinning, samt för att ge en fackman möjlighet att utforma parvis sam- verkande sågklingor så, att dessa erhåller de fördelar som redovisats.The embodiments discussed above are, of course, merely non-existent limiting examples of embodiments of the practice according to the present invention, then obviously further modifications can be made based on the variables that indicated above for adaptation to the diameter of each saw blade and working speed, in order to obtain the desired parallel and smooth movement during a start-up phase, as well as to essentially completely prevent the appearance of magnetism in the saw blades below their relatively counter-rotating motion. The invention is thus in no way limited to previously exemplified embodiments, which are only intended to serve as examples to facilitate the understanding of the method of the present invention, and to enable a professional to design paired acting saw blades so that they receive the benefits of reported.
