Description

537 3 FORFARANDE FOR TILL VERKNING AV EN SEPARATIONSPLAT FOR EN CENTRIFUGALSEPARATOR AV SEPARATIONSPLATTYP Uppfinningens bakgrund Tekniskt comrade Foreliggande uppfinning hanfor sig till ett forfarande for tillverkning av en separationsplat for en centrifugalseparator av separationsplattypen (hadanefter bara hanfOrd till som en separationsplat) som separerar vatska (som skall behandlas) till en vatska och vatska och/eller fast amne och vatska i enlighet med en skillnad i specifik vikt genom hoghastighetsrotation och en hog centrifugalkraft. Background of the Invention Technical Field The present invention relates to a process for manufacturing a separation plate for a centrifugal separator of the separation plate type (which is to be used only as a separator). treated) to a liquid and liquid and / or solid substance and liquid according to a difference in specific gravity by high speed rotation and a high centrifugal force.

Beskrivning av kand teknik En centrifugalseparator av separationsplattypen i enlighet med uppfinningen (hadanefter bara hanford till som en "separator") anvands Mom olika industriomraden. Exempelvis anvands centrifugalseparatorn av separationsplAttyp som en renare som renar brannolja och smorjolja i en marindieselmotor eller avlagsnar fasta orenheter inblandade i de har typerna av olja som vatska som skall behandlas (inblandad vatska som skall behandlas). Description of the Prior Art A separation plate type centrifugal separator in accordance with the invention (hereinafter only referred to as a "separator") is used in various industrial ranges. For example, the separation plate type centrifugal separator is used as a purifier which purifies fuel oil and lubricating oil in a marine diesel engine or removes solid impurities involved in them having the types of oil as liquid to be treated (mixed liquid to be treated).

Strukturen pa den har sortens centrifugalseparator av separationsplattyp (separator) i den kanda tekniken innefattar en separationsplatgrupp. Separationsplatgruppen inkluderar ett flertal separationsplatar som är staplade i en roterande kropp i en riktning for en rotationsaxel hos rotationskroppen. Separationsplaten erhalls genom att bilda en tunn metallplat i form av en trunkerad kon. Ett vertikalt gap, vilket är bildat mellan separationsplatar hos de respektive skikten hos separationsplatgruppen som är positionerade pa den ovre och nedre sidan, det 'il1 saga ett koniskt gap, vilket är bildat mellan en inneryta (nedre yta) pa en konisk yta pa en ovre separationsplat och en ytteryta (ovre yta) pa en konisk yta hos en nedre separationsplat som for de respektive skikten är indelade i, exempelvis atta mellanrum med intervall i den roterande kroppens rotationsriktning genom ett flertal separationsutrymmen som avdelar utskott som är anordnade i en riktning for en konisk generatris hos den nedre separations- platens koniska ytas ytteryta (byre yta). Som ett resultat bildas atta separationsutrymmen. The structure on it has the kind of centrifugal separator of the separation plate type (separator) in the prior art comprises a separation plate group. The separation plate group includes a plurality of separation plates stacked in a rotating body in a direction of an axis of rotation of the rotating body. The separation plate is obtained by forming a thin metal plate in the form of a truncated cone. A vertical gap formed between separation plates of the respective layers of the separation plate group positioned on the upper and lower sides, i.e. a conical gap formed between an inner surface (lower surface) of a conical surface of an upper separation plate and an outer surface (upper surface) on a conical surface of a lower separation plate which for the respective layers are divided into, for example, eight intervals at intervals in the direction of rotation of the rotating body through a plurality of separation spaces dividing projections arranged in one direction for a conical generatris of the outer surface (byre surface) of the lower conical surface of the lower separation plate. As a result, eight separation spaces are formed.

Separationen av en separator som har den ovan namnda strukturen utfores enligt foljande. The separation of a separator having the above-mentioned structure is performed as follows.

Exempelvis nar vatskan som skall behandlas (hadanefter hanford till som en outspadd vatska) sasom brannolja och smorjolja infors i den roterande kroppen i en riktning for en rotationsaxel hos den roterande kroppen, flyter vatskan in i de respektive separationsutrymmena genom flodeshal, vilken passe- rar genom separationsplatgruppen fran den nedre sidan till den ovre sidan hos separationsplatgruppen, genom en centrifugalkraft och sprids i de respektive separationsutrymmena. For example, when the liquid to be treated (then referred to as an undiluted liquid) such as fuel oil and lubricating oil is introduced into the rotating body in a direction of an axis of rotation of the rotating body, the liquid flows into the respective separation spaces through the river hall, which passes through the separation plate group from the lower side to the upper side of the separation plate group, by a centrifugal force and spread in the respective separation spaces.

Medan vatskan (som skall behandlas) till vilken en centrifugalkraft anbringas sprids i separationsutrymmena in i vilka vatskan flyter, flyter vatskan uppat langs en lutande yta pa den nedre koniska ytan mot centrum for separationsplaten, det vill saga i rotationsaxelns riktning mellan de koniska 35 ytorna hos de ovre och nedre separationsplatama. 1 537 3 Under tiden sedimenterar diverse fasta fororeningspartiklar, vilka är inblandade i vatskan som skall behandlas, pa innerytan (nedre ytan) hos den ovre separationsplatens koniska yta, vilken bildar separationsutrymmet, genom centrifugalsedimentering, och strommar (strommar for att matas ut fran separationsutrymmena) till den yttre periferikanten pa separationsutrymmet, det vill saga botten motsvarande en nedre kant pa den koniska ytan, langs den koniska ytan pa vilken fororeningspartiklarna sedimenterar. While the liquid (to be treated) to which a centrifugal force is applied is distributed in the separation spaces into which the liquid flows, the liquid flows upwards along an inclined surface of the lower conical surface towards the center of the separation plate, i.e. in the direction of rotation between the conical surfaces of the upper and lower separation plates. Meanwhile, various solid contaminant particles, which are involved in the liquid to be treated, settle on the inner surface (lower surface) of the conical surface of the upper separation plate, which forms the separation space, by centrifugal sedimentation, and streams (streams to be discharged from the separation spaces). to the outer peripheral edge of the separation space, i.e. the bottom corresponding to a lower edge of the conical surface, along the conical surface on which the contaminant particles settle.

Nar de sedimenterade fasta fOroreningspartiklarna strommar for att matas ut till den yttre periferikan- ten pa separationsutrymmet sasom beskrivits ovan, skickas de fasta fororeningspartiklama till den nedre sidan, det vill saga botten pa den ovre separationsplatens inneryta (separationsplatens yttre pen- feriande) pa separationsutrymmets yttre periferikant sa att de fasta fOroreningspartiklarna sveps bort fran separationsutrymmet av det separationsutrymmesavdelande utskottet medan de fasta fororeningspartiklarna vagleds av det separationsutrymmesavdelande utskottet, vilket är belaget pa den framre sidan, av tva separationsutrymmesavdelande utskott som är anordnade pa den framre och bakre sidan i rotationsriktningen for att bilda (avdela) separationsutrymmet, i detalj, av rotationsframkanten som ar kanten pa det separationsutrymmesavdelande utskottet pa framsidan i rotationsriktningen. When the sedimented solid contaminant particles flow to be discharged to the outer periphery of the separation space as described above, the solid contaminant particles are sent to the lower side, i.e. the bottom of the inner surface of the upper separation plate (the outer outer space of the separation plate). peripheral edge so that the solid contaminant particles are swept away from the separation space by the separation space compartment committee while the solid contaminant particles are waddled by the separation compartment compartment, which is coated on the front side, by two separation compartment compartments on the front side of the (divide) the separation space, in detail, by the leading edge of rotation which is the edge of the separation space dividing projection on the front in the direction of rotation.

Pa det har sattet samlas och avsatts fasta fororeningar, vilka skickas fran vart och ett av separationsutrymmena till den yttre periferikanten darav, vid den yttre periferikanten och nar utrymmet runt separationsplatgruppen i den roterande kroppen. Slutligen ackumuleras fasta fororeningar temporart vid den roterande kroppens avsnitt med maximal diameter, vilken dr en sa kallad insamlingsposition for fasta fororeningar hos den roterande kroppens yttersta periferiutrymme, och matas ut till utsidan av den roterande kroppen med lampliga medel. In this way, solid contaminants have been collected and deposited, which are sent from each of the separation spaces to the outer peripheral edge thereof, at the outer peripheral edge and reach the space around the separation plate group in the rotating body. Finally, solid contaminants accumulate temporarily at the maximum diameter section of the rotating body, which occupies a so-called solid contamination collection position of the outermost peripheral space of the rotating body, and are discharged to the outside of the rotating body by suitable means.

Emellertid finns det ett problem med ett forfarande for att odelat montera de ovan namnda separationsutrymmesavdelande utskottsdelarna (hadanefter separationsutrymmesavdelande utskottet som ett organ, vilket annu inte är integrerat i separationsplatens koniska yta, hanfors till som en separationsut- rymmesavdelande utskottsdel eller bara hanfOrs till som en utskottsdel, och en separationsutrymmesavdelande utskottsdel integrerad i den koniska ytan ar Milford till som ett separationsutrymmesavdelande utskott) pa den koniska ytan (hadanefter Milford till som en konisk kropp) det vill saga en huvudIcropp hos en separationsplat bildad i form av en trunkerad kon, och ett forfarande for tillverkning av en separationsplat for en centrifugalseparator av separationsplattypen som innefattar de separa- tionsutrymmesavdelande utskotten. However, there is a problem with a method of undividedly mounting the above-mentioned separation space department committee members (hereinafter the separation space department committee as a member, which is not yet integrated in the conical surface of the separation plate) is referred to as a separation space department committee part or only a male committee part. , and a separation space dividing committee member integrated in the conical surface is Milford to as a separation space dividing committee) on the conical surface (hereinafter referred to as Milford to as a conical body) i.e. a main body of a separation plate formed in the form of a truncated cone, and a procedure for the manufacture of a separation plate for a centrifugal separator of the separation plate type comprising the separation space dividing committees.

Tidigare bar en separationsplathuvudIcropp, det vill saga en konisk yta (kropp) bildats genom bildande av en tunn metallplat i form av en trunkerad kon, ett antal separationsutrymmesavdelande utskottsdelar (hadanefter bara hanforda till som utskottsdelar) skars frail en plan metallplat vars tjocklek och material är samma eller vasentligen samma som de for separationsplathuvudkroppen, och separationsutrym- mesavdelande utskottsdelar svetsas till ett flertal forutbestamda positioner pa varje separationsplathuvudkropp. Previously, a separation plate head body, i.e. a conical surface (body) formed by forming a thin metal plate in the form of a truncated cone, carried a number of separation space dividing protrusions (henceforth only referred to as protrusions) cut frail a flat metal plate whose thickness and material are the same or substantially the same as those of the separating plate main body, and separating space dividing projections are welded to a plurality of predetermined positions on each separating plate main body.

Emellertid, eftersom den separationsutrymmesavdelande utskottsdelen dr en relativt tunn remsformad liten del ar det svart att hantera den separationsutrymmesavdelande utskottsdelen. Dessutom dr en 2 537 3 process for att noggrant positionera de separationsutrymmesavdelande utskottsdelarna vid forutbestamda positioner pa den koniska ytan, vilken inte är plan, och att odelat tillhandahalla separationsutrymmesavdelande utskottsdelar pa den koniska ytan, som är en huvudkropp av separationsplaten, en svar process som lcraver mycket tid och anstrangningar och en process som har lag produktionseffekti- vitet. However, since the separation space dividing projection member has a relatively thin strip-shaped small portion, it is difficult to handle the separation space dividing projection portion. In addition, a process for accurately positioning the separation space dividing projections at predetermined positions on the non-planar conical surface and inseparably providing separation spacing projections on the conical surface which is a major body of the separation plate over a lot of time and effort and a process that has low production efficiency.

Vidare bor de inre och yttre ytorna pa separationsplaten hos den koniska kroppen, vilken är separationsplatens huvudlcropp och bildad i form av en trunkerad kon, vara speciellt slat i termer av den koniska kroppens funktion. Foljaktligen behover en metallplat, vilken är utmarkt inte endast i hallbarhet utan ocksa i korrosionsmotstand, anvandas och en rostfri stalplat, vilken är gjord av exempelvis SUS304L, SUS316L eller liknande enligt JIS-standard behover anvandas. Av det hdr skdlet fanns en svarighet i att forma en plan rostfri stalplat till en konisk kropp inkluderande en avsmalnande yta. Furthermore, the inner and outer surfaces of the separating plate of the conical body, which is the main body of the separating plate and formed in the form of a truncated cone, should be particularly smooth in terms of the function of the conical body. Consequently, a metal plate, which is excellent not only in durability but also in corrosion resistance, needs to be used and a stainless steel plate, which is made of, for example, SUS304L, SUS316L or the like according to JIS standard needs to be used. Of the hdr shell, there was a responsibility in shaping a flat stainless steel plate into a conical body including a tapered surface.

Tidigare arbetade en person som var kunnig pa trycksvarvning med tid och anstrangning med en trycksvarv (vilken är en maskin som har en struktur liknande en svarv och formar ett objekt som skall bearbetas genom att trycka ett verktyg mot ett objekt som skall bearbetas medan objektet som skall bearbetas roteras med en hog hastighet monterat pa en form) for att forma en plan rostfri stalprat till en konisk kropp som inkluderar en mjuk avsmalnande yta utan distorsion. Som ett resultat av de upprepade studierna genom att prova sig fram kunde uppfinnaren erhalla en arbetsmetod med anvandning av pressdragning med en press och en konisk kropp som är bildad av en trycksvarvmaskin. Previously, a person skilled in pressure turning worked with time and effort with a pressure lathe (which is a machine having a structure similar to a lathe and forming an object to be machined by pressing a tool against an object to be machined while the object to be machined machined is rotated at a high speed mounted on a mold) to form a flat stainless steel plate into a conical body which includes a soft tapered surface without distortion. As a result of the repeated studies by experimenting, the inventor was able to obtain a working method using press drawing with a press and a conical body formed by a pressure turning machine.

Fiireliggande uppfinning tar itu med problemet ovan och ett andamal &ray är att tillhandahalla ett 20 forfarande fOr tillverkning av en separationsplat inkluderande separationsutrymmesavdelande utskott med hog produktionseffektivitet. The present invention addresses the above problem and an object is to provide a method of manufacturing a separation plate including separation space dividing committees with high production efficiency.

Det vill saga ett koniskt gap (ej visat) som ett gap in i vilket vatska som skall behandlas infors (ett antal pilar som lutar uppat i separationsplatssatsen 20 som visas i fig 1 representerar infOrselfiktningen for vatskan som skall behandlas) är bildad mellan en inneryta (nedre yta) 212 pa en konisk yta 21 pa en ovre separationsplAt 2 och en ytteryta (iivre yta) 211 pa en konisk yta 21 hos en nedre separationsplat 2 som for separationsplatarna 2 som visas i fig 2 till 6. A vertical gap is formed between the upper and lower separation plates 2 in the respective layers of the separation space set 20 which are positioned in relation to each other on the upper and lower side in a stacking direction. That is, a conical gap (not shown) as a gap into which liquid to be treated is inserted (a number of arrows inclined upwardly in the separation site set 20 shown in Fig. 1 represents the infiltration of the liquid to be treated) is formed between an inner surface ( lower surface 212 on a conical surface 21 on an upper separation plate 2 and an outer surface (upper surface) 211 on a conical surface 21 of a lower separation plate 2 as for the separation plates 2 shown in Figs. 2 to 6.

Ett flertal separationsutrymmesavdelande utskottsavsnitt 3 är bildade pa ytterytan (den ovre ytan) 211 pa den koniska ytan 21 pa separationsplaten 2, vilken är positionerad pa den relativt nedre sidan, vasentligen i en riktning for en konisk generatris for den koniska ytan 21 med intervall i den roterande kroppens 1 rotationsriktning (en vansterriktning (motsolsriktningen) i fig 1 i den har utforingsformen) sa att, exempelvis, atta avdelade separationsutrymmen 4 bildas. Det vill saga att separationsutrymmesavdelande utskott är anordnade i en radiell riktning i en planvy. A plurality of separation space dividing projection sections 3 are formed on the outer surface (the upper surface) 211 on the conical surface 21 on the separation plate 2, which is positioned on the relatively lower side, substantially in a direction of a conical generator for the conical surface 21 at intervals in the the direction of rotation of the rotating body 1 (a leftward direction (counterclockwise direction) in Fig. 1 in it has the embodiment) said that, for example, eight divided separation spaces 4 are formed. That is to say, separation space dividing committees are arranged in a radial direction in a plan view.

Separationen av vatskan som skall behandlas (brannolja, smorjolja eller liknande innehallande slam eller vatten), vilken utfors av separatom är brett indelad i primar separation och sekundar separation 20 och utfors som foljande centrifugalseparation. The separation of the liquid to be treated (fuel oil, lubricating oil or the like containing sludge or water), which is carried out by the separator, is broadly divided into primary separation and secondary separation and carried out as the following centrifugal separation.

Forst i fig 1 infors vatskan som skall behandlas in i den roterande kroppen 1 frail en inloppsport 11 som är bildad vid en roterande axel hos den roterande kroppen 1 i rotationsriktningen och är separerad i latt vatska som har lag specifik vikt, tung vatska som har hog specifik vikt, ett fast material och liknande, genom en centrifugalkraft som alstras genom hoghastighetsrotation av den roterande kroppen 1 (hadanefter hanfars detta till som en primal- separation). First in Fig. 1 the liquid to be treated is introduced into the rotating body 1 from an inlet port 11 which is formed at a rotating axis of the rotating body 1 in the direction of rotation and is separated into light liquid having a specific gravity, heavy liquid having a high specific gravity, a solid material and the like, by a centrifugal force generated by high speed rotation of the rotating body 1 (henceforth this is referred to as a primal separation).

Den latta vatskan, vilken har en lagre specifik vikt och separeras av den primara separationen, strommar in i flodeshal 22, vilka passerar genom separationsplatsatsen 20 fran den nedre sidan till den ovre sidan av separationsplAtsatsen 20 och tillhandahalles for vane separationsutrymme 4 for att passera genom atminstone de respektive separationsutrymmena 4 i uppatriktningen. Sedan strommar den latta vatskan sekventiellt in i de respektive separationsutrymmena 4 hos det ovre skiktet fran det nedre skiktet och sprids i de respektive separationsutrymmena 4. The light liquid, which has a lower specific gravity and is separated by the primary separation, flows into river hall 22, which passes through the separation site 20 from the lower side to the upper side of the separation site 20 and is provided for habit of separation space 4 to pass through at least the respective separation spaces 4 in the upward direction. Then the light liquid flows sequentially into the respective separation spaces 4 of the upper layer from the lower layer and spreads in the respective separation spaces 4.

Sekundar separation kommer att beslcrivas nedan. Secondary separation will be described below.

En centrifugalkraft anbringas pa vatskan som skall behandlas som sprids i de respektive separationsut- rymmena 4. Medan den sprids i de respektive separationsutrymmena 4 fran stromningshalen 22, strommar vatskan som skall behandlas foljaktligen uppat langs en lutande yta 211 hos den nedre koniska ytan 21 mot centrum av separationsplaten 2, det vill saga i rotationsaxelns riktning, mellan de 537 3 koniska ytorna 21 pa de ovre och nedre separationsplatarna 2 och 2, det viii saga i separationsutrymmena 4 som motsvarar ett gap mellan innerytan (den nedre ytan) 212 pa den ovre separationsplatens 2 koniska yta 21 och ytterytan (den ovre ytan) 211 pa den nedre separationsplatens 2 koniska yta 21. Den har stromningen, det viii saga den uppatriktade stromningen, motsvarar pluraliteten av pilar som lutar uppat i rotationsaxelns riktning i separationsplatsatsen 20 i fig 1. A centrifugal force is applied to the liquid to be treated which is spread in the respective separation spaces 4. While it is spread in the respective separation spaces 4 from the flow hall 22, the liquid to be treated consequently flows upwards along an inclined surface 211 of the lower conical surface 21 towards the center. of the separation plate 2, i.e. in the direction of the axis of rotation, between the 537 3 conical surfaces 21 on the upper and lower separation plates 2 and 2, the viii saw in the separation spaces 4 corresponding to a gap between the inner surface (the lower surface) 212 of the upper separation plate 2 conical surface 21 and the outer surface (the upper surface) 211 on the conical surface 21 of the lower separation plate 2. It has the flow, that is to say the upward flow, corresponding to the plurality of arrows inclined upwards in the direction of the axis of rotation in the separation location 20 in Fig. 1.

Pa det har sattet kommer den relativt latta vatskan som skall behandlas, vilken har strommat mot den ovre sidan, det viii saga det ovre skiktet i separationsplatsatsen 20 genom gapen i separationsutrymmena 4 hos de respektive separationsplatama 2 i separationsplatsatsen 20, slutligen att samlas in som renad vatska frail en insamlingsport 15 som är bildad nara den roterande lcroppens 1 roterande axel visad i fig 1. Once so, the relatively light liquid to be treated, which has flowed towards the upper side, i.e. the upper layer of the separation site 20 through the gaps in the separation spaces 4 of the respective separation plates 2 in the separation site 20, will finally be collected as purified. a collecting port 15 formed near the rotating axis of the rotating body 1 shown in Fig. 1.

Partiklar som har en relativt hog specifik vikt, av olika fasta fororeningspartiklar, vilka är objekt (som skall behandlas) inblandade i vatskan som skall behandlas, nar och samlas under tiden snabbt vid det maximala diameteravsnittet 13 i ett utrymme 12 i den roterande kroppen 1 genom centrifugal sedimentering som fOrorsakas av hoghastighetsrotationen av den roterande kroppen 1. Sedan matas partiklama ut fran utmatningsportar 14 vilka ar bildade vid avsnittet 13 med maximal diameter pa den roterande kroppens 1 midjeomkrets till utsidan av den roterande kroppen 1 vid en lamplig tidpunkt med lampliga medel. Avsnittet 13 med maximal diameter är det yttersta perifera utrymmet nar man ser det fran insidan av den roterande kroppen 1 och är insamlings/ackumuleringspositioner dar fasta fororeningar ackumuleras temporart. Particles having a relatively high specific gravity, of various solid contaminant particles, which are objects (to be treated) involved in the liquid to be treated, collect and collect rapidly in the meantime at the maximum diameter section 13 in a space 12 in the rotating body 1 through centrifugal sedimentation caused by the high speed rotation of the rotating body 1. Then the particles are discharged from discharge ports 14 which are formed at the maximum diameter section 13 of the waist circumference of the rotating body 1 to the outside of the rotating body 1 at a suitable time by suitable means. The section 13 with maximum diameter is the outermost peripheral space when viewed from the inside of the rotating body 1 and is collection / accumulation positions where solid contaminants accumulate temporarily.

Vidare sedimenteras vatskan (som skall behandlas) som har en hog specifik vikt, fasta fororeningspartiklar innehallna i vatskan (som skall behandlas), eller liknande pa innerytan (nedre ytan) 212 pa den koniska ytan 21 pa den ovre separationsplaten, vilken är positionerad pa den relativt ovre sidan (pa taket) och bildar separationsutrymmen 4 (sedimenterar pa separationsutrymmenas 4 tak med en centrifugallcraft) i de respektive separationsutrymmena 4, vilka bildar en bred sedimenteringsyta bildad av separationsplatsatsen 20 (det koniska omradet pa separationsplaten 2 x antalet separationsplatar 2). Sedan strommar vatskan (som skall behandlas) som har en hog specifik vikt, fasta fororeningspartiklar innehallna i vatskan (som skall behandlas), eller liknande mot den yttre periferikanten 41 i separationsutrymmet 4, det viii saga en botten 41 pa den koniska ytan 21 langs den koniska ytan 21 pa vilken materialen sedimenterar. I det foljande betecknas den har stromningen som utloppsstromning fran separationsutrymmet 4. Furthermore, the liquid (to be treated) having a high specific gravity, solid contaminant particles contained in the liquid (to be treated), or the like are sedimented on the inner surface (lower surface) 212 on the conical surface 21 on the upper separation plate, which is positioned on the relatively upper side (on the roof) and forms separation spaces 4 (settles on the roof of the separation spaces 4 with a centrifugal force) in the respective separation spaces 4, which form a wide sedimentation surface formed by the separation site 20 (the conical area on the separation plate 2 x the number of separation plates 2). Then the liquid (to be treated) having a high specific gravity, solid contaminant particles contained in the liquid (to be treated), or the like, flows towards the outer peripheral edge 41 of the separation space 4, i.e. a bottom 41 on the conical surface 21 along the conical surface 21 on which the materials settle. In the following, it is referred to as having the flow as outlet flow from the separation space 4.

Nar de fasta fororeningspartiklarna, vilka har olika massor och sedimenterar i de respektive separationsutrymmena 4 sasom beskrivits ovan, strommar for att matas ut mot den yttre periferikanten 41 pa vart och ett av separationsutrymmena 4, sveps de fasta fororeningspartiklarna av fran separationsutrymmet 4 genom de separationsutrymmesavdelande utskottsavsnitten 3R medan de vagleds sasom visas, exempelvis, stromningsspar enligt prickade pilar i fig 4 eller 5 genom det separationsutrymmesavdelande utskottsavsnittet 3, vilket dr positionerat pa baksidan i rotationsriktningen, (exempelvis det separationsutrymmesavdelande utskottsavsnittet 3R i forhallande till det separationsutrymmesavdelande utskottet betecknat med hanvisningsbeteckning 3F i fig 4) av tva separationsutrymmesavdelande utskottsavsnitt 3 och 3, vilka utgor ett par och är anordnade med intervall pa fram- och baksidorna i 11 537 3 rotationsriktningen sá att en pluralitet av separationsutrymmen 4 bildas (avdelas) i rotationsriktningen; mera exakt av en rotationsframkant 31 som är en kant (framkant) pa det separationsutrymmesavdelande utskottsavsnittet 3R pa framsidan i rotationsriktningen. Darefter skickas de fasta fororeningspartiklama till botten 41 pa den ovre separationsplatens 2 inneryta 212 (den yttre periferikanten 41 pa sepa- rationsplaten 2) pa separationsutrymmets 4 yttre periferikant 41. When the solid contaminant particles, which have different masses and settle in the respective separation spaces 4 as described above, flow to be discharged towards the outer peripheral edge 41 of each of the separation spaces 4, the solid contaminant particles are swept from the separation space 4 by the separation spaces. 3R while the vane joints as shown, for example, flow savings according to dotted arrows in Fig. 4 or 5 through the separation space dividing projection section 3, which is positioned at the rear in the direction of rotation, (e.g. the separation space dividing projection section 3R in relation to the separating part 4) of two separation space dividing committee sections 3 and 3, which form a pair and are arranged at intervals on the front and rear sides in the direction of rotation so that a plurality of separation spaces 4 are formed (divided) in a rotational manner. tningen; more precisely of a rotating leading edge 31 which is an edge (leading edge) of the separation space dividing projection section 3R on the front in the direction of rotation. Thereafter, the solid contaminant particles are sent to the bottom 41 on the inner surface 212 of the upper separation plate 2 (the outer peripheral edge 41 on the separation plate 2) on the outer peripheral edge 41 of the separation space 4.

Vidare nar i fig 1 fasta fororeningar (ej visade) vilka skickas frail vart och ett av separationsutrymmena 4 till den yttre periferikanten 41 ddrav och matas ut till utsidan av separationsplatsatsen 20 sasom beskrivits ovan, utrymmet 12 runt separationsplatsatsen 20 i den roterande lcroppen I. Slutligen, sasom beskrivits ovan, ackumuleras de fasta fororeningama temporart vid avsnittet 13 med maximal diameter pa den roterande kroppen 1, vilken dr en sa kallad insamlingsposition for fasta fororeningar hos den roterande kroppens 1 yttersta periferiutrymme och matas ut till utsidan av den roterande lcroppen 1 fran utmatningsportama 14 med ldmpliga medel. Furthermore, in Fig. 1, solid contaminants (not shown) which are sent from each of the separation spaces 4 to the outer peripheral edge 41 are driven and discharged to the outside of the separation site 20 as described above, the space 12 around the separation site 20 in the rotating body I. Finally, , as described above, the solid contaminants accumulate temporarily at section 13 with maximum diameter of the rotating body 1, which takes a so-called collection position for solid contaminants of the outermost peripheral space of the rotating body 1 and is discharged to the outside of the rotating body 1 from the discharge ports 14 by ldmpliga means.

De separationsutrymmesavdelande utskottsavsnitten 3, mera exakt rotationsframkanten 31 pa de sepa- rationsutrymmesavdelande utskottsavsnitten 3, är bildade sa att massan pa enhetspartiklar okar pa grund av kontakten eller kollisionen (streckade pilar i fig 5) av de olika fasta fororeningspartiklarna som har skillnader i specifik vikt, i rotationsframkanten 31, som fororsakas av skillnaden i en forflyttningshastighet eller tilltrasslingen av stromningsvagar ndr fasta fororeningspartiklar, vilka flyter i vaskan (som skall behandlas) fylld i separationsutrymmet 4, matas ut fran separationsutrymmet 4 till utsidan av separationsutrymmet 4, det vill saga den yttre periferin av separationsplatsatsen 20 medan de vdgleds ldngs rotationsframkanten 31 hos det separationsutrymmesavdelande utskottsavsnittet 3 genom en centrifugalkraft sasom beskrivits ovan. The separation space dividing projection sections 3, more precisely the rotational leading edge 31 of the separating space dividing projection sections 3, are formed so that the mass of unit particles increases due to the contact or collision (dashed arrows in Fig. 5) of the various solid weight contaminants. in the rotating leading edge 31, which is caused by the difference in a speed of movement or the entanglement of flow carriages or solid contaminant particles, which flow in the sink (to be treated) filled in the separation space 4, is discharged from the separation space 4 to the outside of the separation space 4, i.e. the outer per of the separation site 20 while being guided along the rotational leading edge 31 of the separation space dividing projection section 3 by a centrifugal force as described above.

Placeringen av det separationsutrymmesavdelande utskottet 3 i forhallande till den koniska generatrisen for separationsplatens 2 koniska yta 21, det vill saga svetsningen for att integrera det separationsutrymmesavdelande utskottsavsnittet (3) i en fOrutbestdmd position i forhallande till den koniska ytan 21 dr snett lutande for att skara den koniska generatrisen pa den koniska ytan 21, exempelvis i den hdr utforingsformen, men dr inte nodvandigtvis begransad dArtill. Exempelvis kan det separationsutrymmesavdelande utskottsavsnittet (3) vara tillhandahallet (anordnat) att vara parallellt med den koniska generatrisen, pa samma sat som separationsplaten 2 visad i fig 7, det vill saga i riktningen for den koniska generatrisen (fig 7 kommer att beskrivas ytterligare nedan). The position of the separation space dividing projection 3 in relation to the conical generator for the conical surface 21 of the separating plate 2, i.e. the welding to integrate the separation space dividing section (3) in a predetermined position relative to the inclined surface 21 the conical generator on the conical surface 21, for example in the hdr embodiment, but is not necessarily limited dArtill. For example, the separation space dividing committee section (3) may be provided (arranged) to be parallel to the conical generator, in the same way as the separation plate 2 shown in Fig. 7, i.e. in the direction of the conical generator (Fig. 7 will be described further below). .

I vilket fall som helst drivs de separationsutrymmesavdelande utskotten, vilka är odelat svetsade i en pluralitet forutbestamda positioner (Ana i den hdr utforingsformen) som dr installda pa den yttre periferiytan av den koniska ytan 21, det vill saga de integrerade separationsutrymmesavdelande utskotten 3 drivs for att jamforelsevis svepa de fasta fororeningspartiklarna i separationsutrymmena 4 mot botten 41 pa separationsutrymmet 4 i enlighet medcentrifugalkraften (hadanefter hanfors den hdr operationen till som en svepoperation). In any case, the separation space dividing projections, which are undividedly welded in a plurality of predetermined positions (Ana in that embodiment) which are installed on the outer peripheral surface of the conical surface 21, i.e. the integrated separation space dividing projections 3 are driven comparatively sweep the solid contaminant particles in the separation spaces 4 towards the bottom 41 of the separation space 4 in accordance with the centrifugal force (henceforth the hdr operation is referred to as a sweeping operation).

Det separationsutrymmesavdelande utskottet 3 som visas i den hdr utforingsformen sluttar, det vill saga, lutar (hadanefter enkelt hanfort till som "lutande") sa att den ovre dnden av det separationsutrymmesavdelande utskottet 3 dr positionerat pa framsidan av den koniska generatrisen som passerar 12 537 3 genom det separationsutrymmesavdelande utskottet 3 i rotationsriktningen och den nedre anden av det separationsutrymmesavdelande utskottet 3 är positionerat pa baksidan i rotationsriktningen. The separation compartment compartment 3 shown in this embodiment slopes, i.e. slopes (had simply been referred to as "inclined") so that the upper end of the compartment 3 is positioned on the front of the conical generator passing 12 537 3 through the separation space dividing projection 3 in the direction of rotation and the lower end of the separation space dividing projection 3 is positioned at the rear in the direction of rotation.

Under tiden kan rotationsframkanten 31 pa det separationsutrymmesavdelande utskottet 3 bildas i form av en kurva som skjuter ut i en riktning (vanster rotationsriktning i ritningen) motsatt rotations- riktningen (Niger rotationsriktning i ritningen) hos den roterande kroppen 1, over rotationsframkantens 31 hela langd. Meanwhile, the rotation leading edge 31 of the separation space dividing projection 3 can be formed in the form of a curve projecting in a direction (left direction of rotation in the drawing) opposite the direction of rotation (Niger direction of rotation in the drawing) of the rotating body 1, over the entire length of the rotating leading edge 31.

Exempelvis kan rotationsframkanten vara bildad i form av en kurva (ej visad) Over hela langden av framkanten pa det separationsutrymmesavdelande utskottet (stycket) 3, det viii saga rotationsframkanten 31 eller ett avsnitt av hela rotationsframkanten 31 motsvarande botten 41 pa den koniska ytan 21 kan bildas att vara djupt bojt sasom visas i ritningen. For example, the rotating leading edge may be formed in the form of a curve (not shown). Over the entire length of the leading edge of the separation space dividing projection (piece) 3, the said rotating leading edge 31 or a section of the entire rotating leading edge 31 corresponding to the bottom 41 of the conical surface 21 may be formed. to be deeply bent as shown in the drawing.

Om rotationsframkanten är bildad sasom beskrivits ovan, kan det vara mojligt att Oka massan pa partiklar genom kontakten eller kollisionen av fasta fororeningspartiklar i ett relativt brett omrade och att effektivt utfora en svepoperation. Emellertid, behover rotationsframkanten inte nodvandigtvis vara bildad sasom beskrivits ovan och kan vara bildad i form av en rak linje over hela rotationsframkantens 31 langd. Det viii saga det separationsutrymmesavdelande utskottet(stycket) 3 kan i sig sjalvt vara en linjar remsa. If the rotating leading edge is formed as described above, it may be possible to increase the mass of particles through the contact or collision of solid contaminant particles in a relatively wide range and to efficiently perform a sweeping operation. However, the rotational leading edge need not necessarily be formed as described above and may be formed in the form of a straight line over the entire length of the rotating leading edge 31. The viii saga the separation space department committee (paragraph) 3 may in itself be a linear strip.

Samtidigt ar formen pa det V-formade separationsutrymmesavdelande utskottet(stycket) 3 som visas i utforingsformen den optimala formen, vilken har hittats frail upprepade experiment, i prestandaexperiment for separation av fast fas - vatska dar brannolja, smorjolja och liknande for en marin dieselmo- tor anvands som vatska som skall behandlas. Foljaktligen kan formen pa det separationsutrymmesavdelande utskottet 3 varieras beroende pa utforandet eller anvandningen av separatorn, ingredienserna i vatskan som skall behandlas, egenskaperna pa de fasta fororeningarna (partiklama) som ar inblandade i vatskan som skall behandlas och liknande. At the same time, the shape of the V-shaped separation compartment section (paragraph) 3 shown in the embodiment is the optimal shape, which has been found from repeated experiments, in performance experiments for solid phase separation - where fuel oil, lubricating oil and the like for a marine diesel engine used as a liquid to be treated. Accordingly, the shape of the separation compartment compartment 3 can be varied depending on the design or use of the separator, the ingredients of the liquid to be treated, the properties of the solid contaminants (particles) involved in the liquid to be treated and the like.

Exempelvis har det separationsutrymmesavdelande utskottet (stycket) 3 i separationsplaten 2 som visas i fig 7 en linjar form och det separationsutrymmesavdelande utskottet (stycket) 3 ar tillhandahallet (anordnat) att vara parallellt med den koniska generatrisen, det viii saga i den koniska generatrisens riktning. Samtidigt kan fordelarna med ett bojt avsnitt sasom ett V-format avsnitt inte erhallas frail det linjara separationsutrymmesavdelande utskottet (stycket) 3. For example, the separation space division committee (paragraph) 3 in the separation plate 2 shown in Fig. 7 has a linear shape and the separation space division committee (paragraph) 3 is provided (arranged) to be parallel to the conical generator, i.e. in the direction of the conical generator. At the same time, the advantages of a curved section such as a V-shaped section cannot be obtained from the linear separation space department committee (paragraph) 3.

Separationsplaten 3 enligt den har utforingsformen inkluderar en trunkerad konisk kropp (2), vilken ar tillverkad enligt beskrivningen nedan som en huvudkropp. En pluralitet remsformiga separationsutrymmesavdelande utskottsstycken (3), vilka är bildade separat fran den koniska kroppen (2) ar integrerade i den koniska kroppen genom svetsning vid en pluralitet forutbestamda installningspositioner pa den koniska ytan 21 (211), vilken är den yttre periferiytan pa den koniska kroppen (2) som anvands som huvudkroppen, nar den satts in i eller infors i positioneringshalen pa en konisk positioneringsform som tjanar som positioneringsmedel som skall beskrivas nedan var for sig. Foljaktligen är pluraliteten med remsformiga separationsutrymmesavdelande utskott odelat anordnade pa den koniska kroppens yttre periferiyta. 13 537 3 Tillverkningen av separationsplaten 2, vilken inkluderar de separationsutrymmesavdelande utskottsstyckena (3) kommer att beskrivas nedan. The separation plate 3 according to it has the embodiment includes a truncated conical body (2), which is made as described below as a main body. A plurality of strip-shaped separation space dividing projections (3) formed separately from the conical body (2) are integrated in the conical body by welding at a plurality of predetermined installation positions on the conical surface 21 (211), which is the outer peripheral surface of the conical surface. the body (2) used as the main body when inserted into or inserted into the positioning hole on a conical positioning shape which serves as a positioning means to be described below separately. Consequently, the plurality of strip-shaped separation space dividing projections are arranged inseparably on the outer peripheral surface of the conical body. The manufacture of the separation plate 2, which includes the separation space dividing projections (3), will be described below.

Forst maste den koniska kroppen (2) som är separationsplatens huvudkropp, de separationsutrymmesavdelande utskottsstyckena (3) som är bildade separat frAn separationsplaten och den koniska positio5 neringsformen som är positioneringsmedel fiirberedas separat (tillverkas) som forutsattning for tillverkningen av separationsplaten. First, the conical body (2) which is the main body of the separation plate, the separation space dividing projections (3) formed separately from the separation plate and the conical positioning shape which is positioning means must be prepared separately (manufactured) as a prerequisite for the manufacture of the separation plate.

Forfarande for att dra separationsplatens 2 huvudkropp genom tryck Forst kommer ett forfarande for tillverkning av den koniska kroppen (2) vilken dr separationsplAtens 2 huvudkropp, genom tryckdragning att beskrivas nedan med hanvisning till figurema 9 till 17. Den koniska kroppen (2) vilken är separationsplitens 2 huvudkropp bildas vasentligen i en hattform, mera exakt i formen dar ett flansavsnitt 202 (hadanefter hanfort till som ett inatflansavsnitt) som är riktat mot den inre periferin pa ett cirkulart hal 201 (hadanefter hanford till som ett cirkulart toppytehal) format vid toppen av den koniska kroppen (2) som har en trapetsform i ett vertikalt avsnitt bildas horisontellt och ett flansavsnitt 203 (hadanefter hanfort till som ett utAtriktat flansparti) som är riktat mot utsidan bildas horisontellt vid den yttre periferin pa den koniska kroppens (2) botten sasom visas i fig 17 i en nionde process. Method for drawing the main body of the separating plate 2 by pressure First, a method for manufacturing the conical body (2) which draws the main body of the separating plate 2 by pressure drawing will be described below with reference to Figures 9 to 17. The conical body (2) which is the separating plate 2 main body is formed substantially in a hat shape, more precisely in the shape where a flange section 202 (then referred to as an intact flange section) facing the inner periphery of a circular hall 201 (hereinafter referred to as a circular top surface hall) is formed at the top of the cap. the conical body (2) having a trapezoidal shape in a vertical section is formed horizontally and a flange section 203 (hereinafter referred to as an outwardly directed flange portion) facing the outside is formed horizontally at the outer periphery of the bottom of the conical body (2) as shown in Fig. 17 in a ninth process.

I det foljande hanvisas den koniska kroppens (2) vertikala sektionsform till som en hattform och ett avsnitt av den koniska kroppen forutom det hattformade utatriktade flansavsnittet 203 hanvisas till som en hatthuvudkropp. In the following, the vertical sectional shape of the conical body (2) is referred to as a hat shape and a section of the conical body in addition to the hat-shaped outwardly directed flange section 203 is referred to as a hat head body.

Vid tryckdragningen i tillverkningen av den hattformade koniska kroppen (2) finns det en svarighet i att bilda inte bara en avsmalnande yta 204 pa den koniska kroppens (2) periferiyta, vilket är mycket svart att bilda genom dragning, utan ocksa ett R-avsnitt (R1) pA det inatriktade flansavsnittet 202 som är bildat vid den avsmalnande ytans 204 ovre sida och ett R-avsnitt (R2) hos det utatriktade flansavsnittet 203 som är bildat vid den avsmalnande ytans 204 nedre sida. In the pressure drawing in the manufacture of the hat-shaped conical body (2), there is a similarity in forming not only a tapered surface 204 on the peripheral surface of the conical body (2), which is very black to form by drawing, but also an R-section ( R1) pA the straightening flange section 202 formed at the upper side of the tapered surface 204 and an R-section (R2) of the straightening flange section 203 formed at the lower side of the tapered surface 204.

I uppfinningen är det mojligt att tillhandahalla den koniska kroppen (2) vilken är separationsplatens 2 huvudkropp genom tryckdragning eller trycksvarvning som skall beskrivas nedan. In the invention it is possible to provide the conical body (2) which is the main body of the separation plate 2 by pressure drawing or pressure turning which will be described below.

Forsta tryckdragningsprocess (atnne = radmne) For att forma en plan rostfri stalplat till den koniska kroppen (2) vilken inkluderar en avsmalnande yta, genom anvandning av en rostfri stalplat, vilken är gjord av SUS304L, SUS316L eller liknande i JIS- standard som ett amne, forbereds fOrst en fyrkantig plat (hadanefter hanford till som ett fyrkantigt alum) som ett amne 200 sasom visas i fig 9 i en forsta process. Det fyrkantiga amnet 200 erhalls genom att skara en plan plat (standardstorleksplat: 2000 mm x 1000 mm 2B JIS-standard), vilken har en tjocklek ph 0,55 mm, till en erforderlig fyrkantig form, exempelvis en storlek motsvarande 400 mm x 400 mm i enlighet med storleken pa en malseparationsplat 2 (hadanefter hanvisas den har processen till som en fyrkantig materialskamingsprocess). 14 537 3 Andra tryckdragningsprocess (bildande av distorsionsforhindrande cirkuldrt hal) I en andra process sasom visas i fig 10 bildas ett distorsionsforhindrande cirkuldrt hal 205, vilket eliminerar alstringen av distorsion eller sprickor att genereras i amnet (200) vid tryckdragning som skall beskrivas nedan, vid centrum av den fyrkantiga platen 200 genom stansning (hadanefter hanvisas den 5 hdr processen till som en distorsionsfOrhindrande cirkular halskdrningsprocess). First pressure drawing process (atnne = radmne) To form a flat stainless steel plate to the conical body (2) which includes a tapered surface, by using a stainless steel plate, which is made of SUS304L, SUS316L or similar in JIS standard as a blank , a square plate (then hanford to form a square alum) is first prepared as a blank 200 as shown in Fig. 9 in a first process. The square blank 200 is obtained by cutting a flat plate (standard size plate: 2000 mm x 1000 mm 2B JIS standard), which has a thickness of 0.55 mm, into a required square shape, for example a size corresponding to 400 mm x 400 mm in accordance with the size of a grinding separation plate 2 (hereinafter referred to as having the process as a square material combing process). Second Compression Processing (Formation of Distortion Preventing Circular Hall) In a second process as shown in Fig. 10, a distortion preventing circular hall 205 is formed, which eliminates the generation of distortion or cracks to be generated in the blank (200) by compression to be described below, at center of the square plate 200 by punching (hereinafter referred to as the 5 hdr process as a distortion-preventing circular neck-cutting process).

Det distorsionsforhindrande cirkuldra halet 205 bildas av ett cirkuldrt hal vars diameter är mindre an innerdiametem pa toppytans cirkuldra hal 201 som är ett vanligt cirkuldrt hal bildat vid toppytan i den nionde processen som visas i fig 17 som skall beskrivas nedan. Emellertid, for att mera effektivt undertrycka alstringen av distorsion eller sprickor, är det fordelaktigt att ett distorsionsforhindrande cir- kulart hal 205 bildas vars innerdiameter är sa stort som mojligt i det omradet. The anti-distortion circular tail 205 is formed by a circular hole whose diameter is smaller than the inner diameter of the circular surface 201 of the top surface which is a regular circular hole formed at the top surface in the ninth process shown in Fig. 17 to be described below. However, in order to more effectively suppress the generation of distortion or cracks, it is advantageous to form a distortion-preventing circular hall 205 whose inner diameter is as large as possible in that area.

Tredje tryckdragningsprocess (bildande av en munkformad skiva) I en tredje process som visas i fig 11 bildas en skiva 206 genom stansning av periferiavsnittet hos den fyrkantiga platen (amnet), dar det distorsionsforhindrande cirkuldra halet 205 är bildat vid centrum, till formen av en koncentrisk cirkel hos det distorsionsfiirhindrande cirkuldra halet 205 (hadanefter hanvi15 sas den hdr processen till som en skarprocess for att bilda en munkformad skiva). Third pressure drawing process (forming a donut-shaped disc) In a third process shown in Fig. 11, a disc 206 is formed by punching the peripheral section of the square plate (blank), where the distortion-preventing circular tail 205 is formed at the center, in the form of a concentric circle of the distortion-preventing circular tail 205 (hereafter referred to as the hdr process as a cutting process to form a donut-shaped disc).

Ytterdiametern pa skivan 206 är storre an ytterdiametern pa det utatriktade flansavsnittet 203 pa den koniska kroppen (2) hos en fardig produkt som skall bildas i den nionde processen som skall beskrivas nedan. Emellertid är det fordelaktigt for att mera effektivt undertrycka alstringen av distorsion, att skivans 206 ytterdiameter är sa liten som mojligt i det omradet. The outer diameter of the disc 206 is larger than the outer diameter of the outwardly directed flange section 203 of the conical body (2) of a finished product to be formed in the ninth process to be described below. However, in order to more effectively suppress the generation of distortion, it is advantageous that the outer diameter of the disk 206 be as small as possible in that area.

Samtidigt behover de forsta till tredje tryckdragprocessema, det vill saga vasentligen foregaende processer av pressdragningen, inte nodvandigtvis utforas i processordningen som beskrivits i den hdr utforingsformen. Vidare kan den fiirsta till tredje processen eller den andra och tredje processen utforas samtidigt och ordningen pa vissa processer kan omvandas. At the same time, the first to third pressure drawing processes, that is to say essentially preceding processes of the pressing drawing, do not necessarily have to be carried out in the process order described in the hdr embodiment. Furthermore, the first to third processes or the second and third processes can be performed simultaneously and the order of certain processes can be converted.

Dessutom kontrolleras det huruvida en kontaminering, en fororening eller liknande faster vid den munkformade skivan 206 som ett amne fore dragningen i den efterfoljande processen, det viii saga en fjarde tryckdragprocess utfors. Om en kontaminering, fororening eller liknande faster till den munkformade skivan 206, avldgsnas kontamineringen, fororeningen eller liknande (hadanefter hanvisas den hdr processen till som en process for kontrollering av ett munkformat skivmaterial). In addition, it is checked whether a contamination, contamination or similar fastening at the donut-shaped disc 206 as a substance is preferred in the subsequent process, i.e. a fourth pressure drawing process is carried out. If a contamination, contamination or the like adheres to the donut-shaped disc 206, the contamination, contamination or the like is eliminated (hereinafter referred to as this process as a process for checking a donut-shaped disc material).

Forfarande fOr att utfOra trycksvarvning av separationsplats 2 huvudkropp. Procedure for performing pressure turning of separation site 2 main body.

I det foljande kommer ett tillverkningsforfarande for att formge den koniska kroppen (2), vilket är separationsplatens 2 huvudkropp, genom trycksvarvning att beskrivas nedan baserat pa figurerna 18 och 19 med hanvisning till figurerna 9, 16 och 17. In the following, a manufacturing method for shaping the conical body (2), which is the main body of the separation plate 2, by pressure turning will be described below based on Figures 18 and 19 with reference to Figures 9, 16 and 17.

Figurerna 18 och 19 är konceptuella scheman dar en roterande axel hos en anordning motsvarar en horisontell riktning, fig 18 visar ett tillstand dar trycksvarvning pabOrjas och fig 19 visar ett tillstand dar trycksvarvning avslutas. Samtidigt visas amnet 200, vilket är ett objekt som skall bearbetas i figurerna 18 och 19, i en tvarsnittsvy, men strecklinjer som representerar ett tvarsnitt visas ej. Figures 18 and 19 are conceptual diagrams in which a rotating axis of a device corresponds to a horizontal direction, Fig. 18 shows a state in which pressure turning is started and Fig. 19 shows a state in which pressure turning ends. At the same time, the blank 200, which is an object to be processed in Figures 18 and 19, is shown in a cross-sectional view, but dashed lines representing a cross-section are not shown.

I figurerna 18 och 19 anvands exempelvis en automatisk trycksvarvmaskin som en trycksvarvanord- fling 500 (501, 502 och 503). Anordningen 500 innefattar en trunkerad konisk form 501, ett pressverktyg 502 som pressar/fixerar det fyrkantiga amnet 200 mot/till den cirkulara Ovre ytan pa ett trunkerat koniskt avsnitt pa formen 501, och ett roterbart stycke 503 som motsvarar en "paddel" pressad mot det fyrkantiga amnet 200 pressat/fixerat mot/till den cirkulara ovre ytan pa formen 501 med pressverktyget 502. In Figures 18 and 19, for example, an automatic pressure turning machine is used as a pressure turning device 500 (501, 502 and 503). The device 500 comprises a truncated conical mold 501, a pressing tool 502 which presses / fixes the square blank 200 against / to the circular upper surface of a truncated conical section of the mold 501, and a rotatable piece 503 corresponding to a "paddle" pressed against it square blank 200 pressed / fixed against / to the circular upper surface of the mold 501 with the pressing tool 502.

Medan pressverktyget 502, det fyrkantiga amnet 200 och formen 501 roteras odelat runt en axel i tillstandet dar det fyrkantiga amnet 200 är pressat/fixerat mot/till den cirkulara ovre ytan pa formen med pressverktyget 502 sa att centrum pa det fyrkantiga amnet 200 motsvarar centrum pa den cirkulara ovre ytan, pressas stycket 503 mot amnet 200 fran den ovre sidan av formen 501 som har en trapetsformad sektion sasom visas i fig 18 for att forma ett forutbestamt R-avsnitt av R1 och formar den av- smalnande ytan 204 medan den flyttas mot den nedre sidan av trapetsformen langs den sneda sidan av trapetsformen. Sedan stoppas stycket 503 vid positionen for ett forutbestamt R-avsnitt for R2 som visas i fig 19 och separeras fran arnnet 200. While the press tool 502, the square blank 200 and the mold 501 are rotated undividedly about an axis in the state where the square blank 200 is pressed / fixed against / to the circular upper surface of the mold with the press tool 502 so that the center of the square blank 200 corresponds to the center of the circular upper surface, the piece 503 is pressed against the blank 200 from the upper side of the mold 501 having a trapezoidal section as shown in Fig. 18 to form a predetermined R-section of R1 and forms the tapered surface 204 as it is moved towards the lower side of the trapezoidal shape along the oblique side of the trapezoidal shape. Then, the piece 503 is stopped at the position of a predetermined R-section for R2 shown in Fig. 19 and separated from the hearth 200.

Ett stycke som har en form, dar det bojda avsnittet pa R-avsnittet pa R2 formades tidigare vid det stoppade avsnittet nar styckets 503 rorelse stoppas, anvands som stycket 503. Vidare anvands natur- ligtvis en form, vilken har en form motsvarande insidesformen hos separationsplatens 2 huvudkropp som en fardig produkt, det vill saga den koniska kroppen (2), som form 501. Emellertid sasom illustreras i fig 19 har formen emellertid en sned sida (trapetsformad sida) som är tillrackligt mycket langre an den sneda sidan pa den koniska lcroppens (2) avsmalnande yta. A piece having a shape where the curved section of the R section of R2 was previously formed at the stopped section when the movement of the piece 503 is stopped is used as the piece 503. Furthermore, of course, a shape having a shape corresponding to the inside shape of the separation plate is used. 2 main body as a finished product, i.e. the conical body (2), as shape 501. However, as illustrated in Fig. 19, the shape has an oblique side (trapezoidal side) which is sufficiently much longer than the oblique side of the conical body. (2) tapered surface.

Det Ar mojligt att erhalla samma koniska lcropp (2) som den koniska kroppen (2), vilken erhalls vid 35 tidpunkten for slutet av den sjunde pressdragningsprocessen, genom trycksvarvningen enligt den har processen. 537 3 EmeRedid inkluderar den koniska kroppen (2) som visas i fig 19 som erhalles av formningen av en paddel, inte det jamna cirkulara halet 201 som är bildat vid den ovre ytan. FOljaktligen bildas det Matriktade flansavsnittet 202 och det utatriktade flansavsnittet 203 som har den jamna dimensionen inte heller till skillnad frail den koniska kroppen (2) som visas i fig 17. It is possible to obtain the same conical body (2) as the conical body (2), which is obtained at the time of the end of the seventh pressing process, by the pressure turning according to the process. 537 3 EmeRedid includes the conical body (2) shown in Fig. 19 obtained by the formation of a paddle, not the smooth circular tail 201 formed at the upper surface. Consequently, the Matriarched flange section 202 and the outwardly directed flange section 203 having the smooth dimension are also formed, unlike the conical body (2) shown in Fig. 17.

Darfor utfors bearbetningen for dessa, det vill saga de attonde, nionde och tionde pressdragningsprocesserna dessutom. Therefore, the processing for these is carried out, that is to say the eighteenth, ninth and tenth press drawing processes in addition.

Enligt den ovan namnda trycksvarvningen är det salunda mojligt att erhalla samma produkt som produkten, vilken erhalles genom de (fiirsta till tionde) trycksvarvprocesserna, genom att utfora den forsta pressdragningsprocessen, trycksvarvprocessen och de attonde till tionde pressdragningsprocesserna utan att utfora de andra till sjatte pressdragningsprocesserna som har beskrivits i den ovan namnda utforingsformen. According to the above-mentioned pressure turning, it is thus possible to obtain the same product as the product obtained by the (first to tenth) pressure turning processes, by performing the first pressing process, the pressure turning process and the eighth to tenth pressing processes without performing the second to sixth processes as drawing. has been described in the above-mentioned embodiment.

Tillverkning av ett separationsutrymmesavdelande utskottsstycke. Manufacture of a separation space departmental piece.

Det separationsutrymmesavdelande utskottsstycket (3) är tidigare bildat i en onskad form genom att stansa ett plant amne genom att anvanda lampliga formningsmedel, exempelvis en stansmaskin eller 15 liknande (stansprocess). The separation space dividing projection piece (3) is previously formed in a desired shape by punching a flat blank by using suitable forming means, for example a punching machine or the like (punching process).

Exempelvis bildas det separationsutrymmesavdelande utskottet i en V-form sasom beskrivits ovan eller i form av en rak remsa som visas i fig 7 (hadanefter hanvisas den har processen till som en process for att bilda ett utskottsstycke). For example, the separation space dividing committee is formed in a V-shape as described above or in the form of a straight strip as shown in Fig. 7 (hereinafter referred to as having the process as a process for forming a committee piece).

Nar det separationsutrymmesavdelande utskottsstycket (3) bildas, speciellt ett utskottsstycke, dar det separationsutrymmesavdelande utskottsstycket är parallellt med den koniska generatrisen for den koniska ytan eller anordnad i en vinkel nastan parallellt med den koniska generatrisen, exakt i en sned riktning, for att snedvridas mot den ovre ytan darav (ytan motsatt kontaktytan som kommer i kontakt med den koniska ytan = bakytan) i den longitudinella riktningen darav (i det foljande kallas den har processen en snedvridningsprocess). When the separation space dividing protrusion piece (3) is formed, especially a protrusion piece, where the separation space dividing protrusion piece is parallel to the conical generator for the conical surface or arranged at an angle almost parallel to the conical generator, exactly in an oblique direction the upper surface thereof (the surface opposite the contact surface which comes into contact with the conical surface = the rear surface) in the longitudinal direction thereof (hereinafter referred to as the process has a distortion process).

En fordel med bildande i en snedvriden form kommer att beskrivas i den foljande svetsprocessen. Ett onskat separationsutrymmesavdelande utskottsstycke tillverkas med ovan namnda processer. An advantage of forming in a distorted form will be described in the following welding process. A desired separation space dividing committee piece is manufactured with the above-mentioned processes.

Framstallning (tillverkning) av konisk positioneringsform. Manufacture (manufacture) of conical positioning mold.

Som en konisk positioneringsform som positioneringsmedel, vilken passar en forutbestamd position dar det separationsutrymmesavdelande utskottsstycket (3) är integrerat i den koniska lcroppens (2) yta, det vill saga en huvudicropp hos separationsplaten 2, anvands en trunkerad konisk form, vilken har samma form eller en liknande form och av vilken endast en del ar frankopplingsbart inpassad till atminstone den koniska ytan pa en separationsplathuvudlcropp, vilken är frankopplingsbart och nara inpassad till separationsplatens 2 koniska ytas yttre periferi. 21 537 3 Nar den är nara inpassad i den axiella riktningen for den koniska formen visad av pilen i fig 8 for att vara overlagrad den koniska kroppens (2) koniska yta 211, det viii saga en huvudkropp hos separationsplaten 2, innefattar en konisk positioneringsform 50 visad i utforingsformen i fig 8 positioneringshal 51 som har samma form som, exempelvis, de separationsutrymmesavdelande utskottsstycke- na (3) och in i vilka de separationsutrymmesavdelande utskottsstyckena (3) är nara inpassade medan de separationsutrymmesavdelande utskotten är integrerade i en konisk kropp (21) vid forutbestamda avsnitt motsvarande fomtbestamda positioner pa separationsplaten 2 ddr de separationsutrymmesavdelande utskottsstyckena (3) är svetsade. As a conical positioning shape as a positioning means, which fits a predetermined position where the separation space dividing projection piece (3) is integrated in the surface of the conical body (2), i.e. a main body of the separation plate 2, a truncated conical shape is used, which has the same shape or a similar shape and of which only a part is detachably fitted to at least the conical surface of a separation plate main body, which is detachable and more closely fitted to the outer periphery of the conical surface of the separation plate 2. When closely fitted in the axial direction of the conical shape shown by the arrow in Fig. 8 to be superimposed on the conical surface 211 of the conical body (2), i.e. a main body of the separation plate 2, a conical positioning shape 50 comprises shown in the embodiment in Fig. 8 positioning hall 51 which has the same shape as, for example, the separation space dividing projections (3) and into which the separation spacing projections (3) are closely fitted while the separation spacing projections are integrated in a conical body (21). at predetermined sections corresponding to predetermined positions on the separation plate 2 where the separation space dividing projection pieces (3) are welded.

Sisom är kant frail det visade tillstandet erhalles den koniska positioneringsformen 50 (hadanefter hanford till som en konisk form) genom avdelning av den koniska kroppen (21) som är en huvudkropp for separationsplaten 2 ddr den koniska positioneringsformen 50 anbringas och de separationsutrymmesavdelande utskottsstyckena (3) svetsas, som det är och bildande av positioneringshalen 51. If the edge shown in the condition shown is obtained, the conical positioning shape 50 (hereinafter referred to as a conical shape) is obtained by dividing the conical body (21) which is a main body for the separation plate 2 when the conical positioning shape 50 is applied and the separation space dividing projections (3). welded as is and forming the positioning tail 51.

Foljaktligen bildas stromningshalen 22 som de dr. Emellertid kan stromningshalen 22 vara onodvandiga och inte behova bildas. Consequently, the flow tail 22 is formed as the dr. However, the flow hole 22 may be unnecessary and need not be formed.

Som konisk positioneringsform 50 behover den ovan namnda separationsplaten 2 inte nodvandigtvis avdelas och en separat konisk form kan bildas. Emellertid kan det vara mojligt att snabbt och enkelt erhalla den koniska positioneringsformen 50 genom att avleda separationsplaten och kostnaden for den koniska positioneringsformen blir ekonomisk. As a conical positioning shape 50, the above-mentioned separation plate 2 need not necessarily be separated and a separate conical shape can be formed. However, it may be possible to quickly and easily obtain the conical positioning shape 50 by deflecting the separation plate and the cost of the conical positioning shape becomes economical.

I vilket fall som heist är det fordelaktigt att formen pa den koniska positioneringsformen 50 blir sam20 ma som eller liknande formen pa separationsplaten 2 hos den trunkerade konformen och den koniska positioneringsformen har en storlek som fullstandigt tacker hela den yttre ytan pa separationsplaten i den koniska formens axiella riktning. In any case, it is advantageous that the shape of the conical positioning mold 50 becomes the same as or similar to the shape of the separation plate 2 of the truncated conical mold and the conical positioning mold has a size that completely thanks the entire outer surface of the separation plate in the axial shape of the conical mold. direction.

Vidare, om den koniska positioneringsformen är bildad genom avledning av separationsplaten 2 är separationsplatens 2 koniska yta tunn. Av det hdr skalet kan separationsplatens koniska yta goras tjock 25 genom att tillhandahalla lampliga forstarkningsorgan (ej visade) vid de inre periferikanterna pa positioneringshalen 51, det viii saga vid Atminstone 'pada kanterna pa langa hal bildade i form av en remsa. Furthermore, if the conical positioning shape is formed by deflection of the separation plate 2, the conical surface of the separation plate 2 is thin. From this hard shell, the conical surface of the separation plate can be made thick by providing suitable reinforcing means (not shown) at the inner peripheral edges of the positioning hole 51, that is to say at least at the long edges formed in the form of a strip.

Om tjockleken 'Ras vid kantema pa positioneringshalen 51 bildade vid den koniska positioneringsformen 50 sasom beskrivits ovan, kan det vara mdjligt att noggrant fora in de separationsutrymmesavdelande utskottsstyckena (3) i positioneringshalen 51 utan ett fel ndr de separationsutrymmesavdelan30 de utskottsstyckena fors in i positioneringshalen och att snabbt och enkelt utfora ett arbete. If the thickness 'is' at the edges of the positioning hole 51 formed at the conical positioning mold 50 as described above, it may be possible to carefully insert the separation space dividing projections (3) into the positioning hole 51 without a defect in the separation space divisions 30 of the projection pieces. quickly and easily perform a job.

En svetsprocess vilken helt ordnar de remsformiga separationsutrymmesavdelande utskottsstyckena (3) vid en forutbestamd position pa separationsplatens 2 koniska yta 21, kommer att beskrivas nedan. A welding process which completely arranges the strip-shaped separation space dividing projections (3) at a predetermined position on the conical surface 21 of the separation plate 2 will be described below.

Forsta svetsprocess (inpassningsprocess). First welding process (fitting process).

SAsom visas i fig 8 är den koniska positioneringsformen 50 frikopplingsbart inpassad for att vara Over-35 lagrad pa den yttre periferin pa separationsplAtens 2 koniska yta 21 i den koniska formens axiella rikt- 22 537 3 fling, och ar nara inpassad sá att den koniska positioneringsformens 50 positioneringshal 51 är nog-grant overlagrade vid fOrutbestdmda positioner pa separationsplAtens 2 koniska yta 21, det viii saga vid de installda positionema for de separationsutrymmesavdelande utskotten 3, sá att separationsplaten 2 och den koniska formen 50 är integrerade i varandra (hadanefter hanvisas detta till som en inpass- ningsprocess for inpassning av separationsplaten till den koniska formen). As shown in Fig. 8, the conical positioning shape 50 is releasably fitted to be superimposed on the outer periphery of the conical surface 21 of the separation plate 2 in the axial direction of the conical shape, and is more closely fitted so that the conical positioning shape Positioning hall 51 is substantially superimposed at predetermined positions on the conical surface 21 of the separation plate 2, i.e. at the installed positions of the separation space dividing projections 3, so that the separation plate 2 and the conical shape 50 are integrated into each other (hereinafter referred to as a fitting process for fitting the separation plate to the conical shape).

Andra svetsprocess Efter det fors de separationsutrymmesavdelande utskottsstyckena (3), vilka dr separat bildade, in i den koniska positioneringsformens 50 positioneringshal 51 och de separationsutrymmesavdelande utskottsstyckena (3) svetsas till separationsplAtens 2 koniska yta 21. Second welding process After that, the separation space dividing projections (3), which are formed separately, are moved into the positioning hall 51 of the conical positioning mold 50 and the separation space dividing projections (3) are welded to the conical surface 21 of the separation plate 2.

Exempelvis utfors som svetsning, punktsvetsning sekventiellt frail en ande av det separationsutrymmesavdelande utskottsstycket (3) mot den andra anden ddrav vid svetspunkter (ej visade), vilka är sekventiellt installda vid ldmpliga intervall i det remsformiga separationsutrymmesavdelande utskottsstyckets (3) longitudinella riktning sa att separationsplaten och den koniska formen är integrerade i varandra. For example, as welding, spot welding is performed sequentially from one end of the separation space dividing protrusion piece (3) towards the other second drive at welding points (not shown), which are sequentially set at suitable intervals in the strip-shaped separation space dividing section and longitudinal projection. the conical shape are integrated into each other.

Svetsning vid initialt positioneringshal Si. Welding at initial positioning hall Si.

Forst, medan den andra dnden av ett separationsutrymmesavdelande utskottsstycke (3) halls for hand, fors en ande av det separationsutrymmesavdelande utskottsstycket (3) in i en ande av positioneringshAlet 51. Sedan, medan svetspunkten for atminstone en ande av det separationsutrymmesavdelande utskottsstycket (3) pressas for att sjunka in i positioneringshalet 51 mot en repulsiv kraft for snedvrid- ningen av det separationsutrymmesavdelande utskottsstycket (3), utfors punktsvetsning vid svetspunkten med den andra handen. First, while the other end of a separation space dividing projection piece (3) is held by hand, a spirit of the separation space dividing projection piece (3) is inserted into a spirit of the positioning hole 51. Then, while the welding point of at least one spirit of the separation space dividing section (3) is pressed to sink into the positioning tail 51 against a repulsive force for the distortion of the separation space dividing projection piece (3), spot welding is performed at the welding point with the other hand.

Efter det pressas den foljande svetspunkten for att sjunka i positioneringshalet 51 med handen som hailer det separationsutrymmesavdelande utskottsstycket (3) och punktsvetsning utfors vid den foljande svetspunkten med den andra handen. After that, the following welding point is pressed to sink in the positioning tail 51 with the hand that hails the separation space dividing projection piece (3) and spot welding is performed at the next welding point with the other hand.

Sedan repeteras de foregaende processerna pa samma sat. Sekventiellt pressas svetspunkten med en hand for att sjunka vid ett installningshal, punktsvetsning utfors vid svetspunkten med den andra handen och svetsningen av det separationsutrymmesavdelande utskottsstycket (3) slutfors (i det foljande hdnvisas den har processen till som en punktsvetsningsprocess). Then the previous processes are repeated in the same way. Sequentially, the welding point is pressed with one hand to sink at an installation hall, spot welding is performed at the welding point with the other hand and the welding of the separation space dividing projection piece (3) is completed (hereinafter referred to as having the process as a spot welding process).

I punktsvetsningsprocessen utfiirs svetsning medan det separationsutrymmesavdelande utskottsstycket (3) fors in nagot i positioneringshalet 51, det viii saga svetspunkten svetsas sekventiellt och kontinuerligt vid svetspunkten fran en remsformad ande mot den andra anden pa det separationsutrymmesavdelande utskottet medan det separationsutrymmesavdelande utskottsstycket (3) korrekt och gradvis in-fors i positioneringshalet 51 fran en remsformig ande mot den andra ddrav. In the spot welding process, welding is performed while the separation space dividing projection piece (3) is inserted into the positioning tail 51, the said welding point being welded sequentially and continuously at the welding point from a strip-shaped spirit to the other on the separation space dividing partition. is inserted into the positioning tail 51 from a strip-shaped spirit towards the second drive gear.

Enligt det har svetsforfarandet, svetsas svetspunkten sekventiellt medan svetspunkten beludftas och 35 svetsning utfors medan den pa rat sdtt kommer i kontakt med en forutbestamd position. Foljaktligen 23 537 3 stabiliseras det separationsutrymmesavdelande utskottsstycket (3) vid en forutbestamd svetspunkt, svetsas pa ratt satt utan positionsavvikelse och integreras i separationsplaten 2. According to the welding method, the welding point is welded sequentially while the welding point is being aerated and welding is performed while it is in contact with a predetermined position. Consequently, the separation space dividing protrusion piece (3) is stabilized at a predetermined welding point, welded in a straight line without position deviation and integrated in the separation plate 2.

Emellertid är svetsforfarandet inte begransat dartill. Exempelvis kan hela det separationsutrymmesav- delande utskottsstycket (3) inforas i positioneringshalet 51 vid en tidpunkt och kan punktsvetsas. However, the welding process is not limited thereto. For example, the entire partition dividing piece (3) can be inserted into the positioning tail 51 at a time and can be spot welded.

Vidare i exemplet av svetsningen enligt utforingsformen har punktsvetsning beskrivits som utfors vid positioner som är streckade i den longitudinella riktningen for en remsa, det viii saga det separationsutrymmesavdelande utskottsstycket (3) stracker sig in i formen av en remsa. Emellertid kan andra lampliga svetsmedel anvandas. Furthermore, in the example of the welding according to the embodiment, spot welding has been described as being performed at positions which are dashed in the longitudinal direction of a strip, i.e. the separation space dividing projection piece (3) extends into the shape of a strip. However, other suitable welding agents can be used.

Samtidigt kan langden pa det separationsutrymmesavdelande utskottsstycket (3), vilket svetsas har foretradesvis ha langden som stracker sig fran den koniska ytans 21 ovansida mot botten, det viii saga den nedre sidan 41 ndr det separationsutrymmesavdelande utskottet är odelat svetsat till den koniska ytan 21. At the same time, the length of the separation space dividing projection piece (3) which is welded may preferably have the length extending from the upper side of the conical surface 21 towards the bottom, i.e. the lower side 41 when the separation space dividing projection is undividedly welded to the conical surface 21.

Svetsning vid det andra positioneringshalet 51 Darefter kan det andra positioneringshalet 51, dar svetsningen av det separationsutrymmesavdelande utskottsstycket (3) utfors, vara ett positioneringshal 51 intill det ursprungliga positioneringshalet 51 eller det andra lampliga positioneringshalet. Om emellertid, ett positioneringshal motsatt positioneringshalet 51 som anvands i den ursprungliga (forsta) svetsningen, exempelvis ett positioneringshal 51 positionerat vid en position motsvarande en fasskillnad pa 180° valjs och svetsas, är den koniska for-men (2, 20) som är overlagrad pa separationsplaten 2 vidare positionerad vid slutforandet av den andra svetsningen av de separationsutrymmesavdelande utskottsstyckena (3) som svetsas vid tva positioner pa avstand fran varandra vid en fasskillnad pa 180°. Positioneringshalen 51, dar andra separationsutrymmesavdelande utskottsstycken (3) skall svetsas, faststalls naturligtvis vid de forutbestamda positionerna pa separationsplaten 2 och positioneras mera bekvamt och palitligt. Foljaktligen kan det vara mojligt att mera palitligt integrera det separationsutrymmesavdelande utskottsstycket (3) vid den for- utbestamda positionen pa separationsplaten 2. Welding at the second positioning tail 51 Thereafter, the second positioning tail 51, where the welding of the separation space dividing projection piece (3) is performed, may be a positioning hall 51 adjacent the original positioning tail 51 or the second lamp positioning tail. However, if a positioning hall opposite the positioning tail 51 used in the original (first) welding, for example a positioning hall 51 positioned at a position corresponding to a phase difference of 180 ° is selected and welded, the conical shape (2, 20) is superimposed on the separation plate 2 further positioned at the completion of the second welding of the separation space dividing projection pieces (3) which are welded at two positions at a distance from each other at a phase difference of 180 °. The positioning hall 51, where other separation space dividing projections (3) are to be welded, is of course fixed at the predetermined positions on the separation plate 2 and is positioned more conveniently and reliably. Consequently, it may be possible to more reliably integrate the separation space dividing piece (3) at the predetermined position on the separation plate 2.

I vilket fall som heist medan den ovan narrinda koniska positioneringsformen 50 anvands och den koniska positioneringsformen är nara inpassad att vara overlagrad pa separationsplatens 2 koniska yta 21, utfors punktsvetsning medan det remsformiga separationsutrymmesavdelande utskottet fors in i positioneringshalet 51 for att gradvis inpassas fran en ande av det remsformiga separationsutrymmes- avdelande utskottsstycket (3) mot den andra anden darav. Sedan, nar det separationsutrymmesavdelande utskottsstycket (3) svetsas med en lamplig svetsmaskin med anvandning av en forutbestamd position, det viii saga positioneringshalet 51, kan det vara mojligt att odelat tillhandahalla de separationsutrymmesavdelande utskottsstyckena (3) vid alla de fOrutbestamda positionerna pa separations-platen 2 medan separationsplaten 2 och den koniska positioneringsformen 50, vilka ar overlagrade och odelat inpassade, roteras runt den koniska formens axel i en omkretsriktning och ett flertal forutbestamda positioner (positioneringshal 51) installda i omkretsriktningen for separationsplaten 2 roteras 24 537 3 till forutbestamda svetspositioner for svetsmaskinen. Foljaktligen kan det vara mojligt att effektivt utfora svetsningen av det separationsutrymmesavdelande utskottsstycket (3). In any case, while the above-mentioned conical positioning mold 50 is used and the conical positioning mold is closely fitted to be superimposed on the conical surface 21 of the separating plate 2, spot welding is performed while the strip-shaped separating space dividing projection is inserted into the positioning tail 51 to gradually adjust from a the strip-shaped separation space dividing projection piece (3) towards the second spirit thereof. Then, when the separation space dividing projection piece (3) is welded with a suitable welding machine using a predetermined position, the viii saga positioning tail 51, it may be possible to provide in part the separation space dividing projection pieces (3) at all the positions of the predetermined position. while the separation plate 2 and the conical positioning mold 50, which are superimposed and integrally fitted, are rotated about the axis of the conical mold in a circumferential direction and a plurality of predetermined positions (positioning hall 51) set in the circumferential direction of the separation plate 2 are rotated to predetermined welding positions for welding. Accordingly, it may be possible to efficiently perform the welding of the separation space dividing piece (3).
