Mupunga. 1. Munguva yekutenderera kweiyo vertical roll feed system, iyo inotungamira yekumusoro "inokotama" pamberi pekukotama rolls. Mupendero uchangobva kuchekwa wekutevera unozotsvedzerwa pamusoro pemupendero unotungamira, wogadzikwa uye woiswa welded kugadzira goko rakakungurutswa.
Chero ani anoshanda muindasitiri yekugadzira simbi angangove akajairana nezvigayo zvinotenderedza, angave ari pre-nip mill, double-nip three-roll mill, three-roll geometric translational mills, kana four-roll mills. Chimwe nechimwe chazvo chine zvisingakwanisi uye zvakanakira, asi vane chinhu chimwe chete chakafanana: vanokungurusa mapepa nemahwendefa munzvimbo yakatwasuka.
Imwe nzira isinganyanyozivikanwa inosanganisira kutsveta munzira yakatwasuka. Kufanana nedzimwe nzira, kupenengura kwakatwasuka kune zvakunogumira uye zvakanakira. Aya masimba anogara achigadzirisa rimwe rematambudziko maviri. Imwe yacho ndeye mhedzisiro yegiravhiti pane iyo workpiece panguva yekukungurutsa, uye imwe yacho kusashanda kwekugadzirisa zvinhu. Kuvandudzwa kunogona kuvandudza mafambiro ebasa uye pakupedzisira kuwedzera kukwikwidza kwemugadziri.
Vertical rolling tekinoroji haisi itsva. Midzi yaro inogona kuteverwa kumashure akati wandei etsika masisitimu akagadzirwa muma1970s. Pakazosvika ma1990s, vamwe vavaki vemuchina vaipa vertical rolling mill seyakajairwa chigadzirwa mutsara. Iyi tekinoroji yakagamuchirwa nemaindasitiri akasiyana, kunyanya mumunda wekuvaka matangi.
Matangi akajairika uye midziyo inowanzogadzirwa yakatwasuka zvinosanganisira ayo anoshandiswa mumaindasitiri ezvekudya, emukaka, waini, kubika, nemishonga; API mafuta ekuchengetedza matangi; matangi emvura akakwenenzverwa ekurima kana kuchengetedza mvura. Vertical rolls inoderedza zvakanyanya kubata zvinhu, kazhinji inopa kunaka kwekukotama, uye zvakanyanya kubata nhanho inotevera yekuungana, kurongeka uye welding.
Imwe bhenefiti inoratidzwa apo simba rekuchengetedza rezvinhu zvishoma. Vertical storage of slabs kana slabs inoda nzvimbo shoma pane kuchengeta slabs kana slabs panzvimbo yakati sandara.
Funga nezvechitoro umo mitumbi yakakura-dhayamita matangi (kana kuti "matanho") akakungurutswa pamapumburu akachinjika. Mushure mekukunguruka, vashandisi vanoita welding, kudzikisa mafuremu ekumativi, uye kuwedzera goko rakamoneredzwa. Sezvo goko rakatetepa richinyura pasi pehuremu hwaro, rinofanirwa kusimbiswa nezvimisikidza kana zvitsigiro kana kutenderedzwa kune yakamira.
Huwandu hwakadai hwekushanda — kudyisa mapuranga kubva kune akachinjika kuenda kune akachinjika ma rolls chete kuti aabvise mushure mekuumburudzwa nekuatenderedza kuti aturikire - anogona kugadzira marudzi ese ematambudziko ekugadzira. Nekuda kwekutenderera kwakamira, chitoro chinobvisa zvese zvepakati kugadzirisa. Mashiti kana mapuranga anodyiswa akatwasuka uye akakungurutswa, akachengetedzwa, obva asimudzwa mudenga kuitira kuvhiya kunotevera. Paunenge uchisimudza, tangi huturu haidzivisi giravhiti, saka haikotami pasi pehuremu hwayo.
Kumwe kutenderedzwa kwakatwasuka kunoitika pamichina ye-four-roll, kunyanya kumatangi madiki (kazhinji asingasviki 8 mafiti mudhayamita) anozotakurwa achidzika nekudzika uye anogadziriswa akatwasuka. Iyo 4-roll system inobvumira kutenderedza zvakare kubvisa unbent flats (apo mipumburu inobata pepa), iyo inonyanya kuoneka pamadiki madiki cores.
Muzviitiko zvakawanda, kutenderedzwa kwematangi kunoitwa pamakina matatu-roll ane kaviri clamping geometry, inodyiswa kubva kumarata esimbi kana zvakananga kubva kumakoiri (iyi nzira iri kuwedzera kuwanda). Mune izvi setups, mushandisi anoshandisa radius geji kana template kuyera radius yefenzi. Vanogadzirisa mabheji ekukotama pavanobata kumucheto kunotungamirira kwewebhu, uye zvakare zvakare apo webhu inopfuurira kudya. Sezvo bobbin ichiramba ichipinda mukati mayo maronda akasimba, kuseri kwechinhu kunowedzera uye mushandisi anofambisa bhobho kuti ikonzere kubhenda kuripe.
Iyo elasticity inotsamira pane zvinhu zvezvinhu uye rudzi rwekoiri. Iyo yemukati dhayamita (ID) yekoiri yakakosha. Zvimwe zvinhu zvakaenzana, coil iri 20 inches. Iyo ID ine ronda rakasimba uye ine kubhuroka kwakawanda kupfuura iyo coil yakakuvadzwa kusvika 26 inches. IDENTIFER.
Mufananidzo 2. Vertical scrolling yave chikamu chakakosha cheakawanda matangi ekuisa munda. Paunenge uchishandisa crane, maitiro acho anowanzotanga pauriri hwepamusoro uye anoshanda achidzika. Tarira musono wega wakamira pamusoro pedenga.
Ziva, zvisinei, kuti kukunguruka muzvimwiro zvakasiana zvakanyanya nekukungurutsira ndiro yakakora pamapepa akachinjika. Muchiitiko chekupedzisira, vashandi vanoshanda nesimba kuti vaone kuti mipendero yepepa inoenderana chaizvo pakupera kwekutenderera. Mashizha makobvu akakungurutswa kuita madhayamita matete haashande zvakare.
Kana uchigadzira magaba ane roll-fed vertical rolls, mushandisi haakwanise kuunza mipendero pamwe chete pakupera kwekutenderera kutenderera nekuti, hongu, pepa rinouya rakananga kubva mupumburu. Munguva yekukungurusa, pepa rine mucheto unotungamira, asi harizove neinotevedzana kusvika yachekwa kubva pamupumburu. Panyaya yezvirongwa izvi, mupumburu unoputirwa mudenderedzwa rakazara mupumburu usati wanyatsokotama, wozocheka wapedza (ona Mufananidzo 1). Mupendero uchangobva kuchekwa wekutevera unozotsvedzerwa pamusoro pemupendero wekutungamira, wogadzikwa, wobva wasundirwa kuita goko rakakunguruka.
Iko-kupeta-peta uye kutenderedzazve mumichina yakawanda-yakadyiswa haishande, zvichireva kuti kazhinji ine mabreak pamicheto inotungamira uye inoteedzera (yakafanana nemafurati asina kubhenda mune isiri-roll-fed rolling). Zvikamu izvi zvinowanzo shandiswa patsva. Nekudaro, mabhizinesi mazhinji anoona zvimedu semutengo mudiki kubhadhara kune ese mabatiro ekugadzirisa zvinhu izvo vertical rollers anovapa.
Nekudaro, mamwe mabhizinesi anoda kuwana zvakanyanya kubva pazvinhu zvaanazvo, saka vanosarudza akavakirwa-mukati roller leveler masisitimu. Iwo akafanana nemana-roll straighteners pamitsetse yekubata roll, inongopinduka yakatarisa pasi. Magadzirirwo akajairwa anosanganisira 7-roll uye 12-roll straighteners anoshandisa musanganiswa wekutora-up, straightener uye kubhenda rolls. Muchina wekururamisa haungodzikisi kudonhedza kwega ega rakaremara sleeve, asi zvakare unowedzera kuchinjika kwehurongwa, kureva kuti sisitimu haigone kuburitsa kwete zvikamu zvakatenderedzwa chete, asiwo slabs.
Iyo nzira yekuyera haigone kuburitsa mhedzisiro yemasisitimu ekuyeresa anowanzo shandiswa munzvimbo dzebasa, asi inogona kuburitsa zvinhu zvakapfava zvakakwana kucheka nelaser kana plasma. Izvi zvinoreva kuti vagadziri vanogona kushandisa makoiri kune ese ari maviri akatwasuka nekutsemura.
Fungidzira kuti mushandisi anokungurutsa kese yechikamu chegaba anogamuchira odha yekutumira simbi yakakasharara patafura yekucheka plasma. Mushure mekunge apeta tumakesi ndokudzitumira kuzasi, akagadzira hurongwa hwekuti michina yekutwasanura isapinzwa mumhepo yakananga. Pane kudaro, iyo leveler inopa chikafu chakatsetseka chinogona kutemwa kureba, kugadzira plasma yekucheka slab.
Mushure mekucheka batch yezvisina kuvharwa, mushandisi anogadzirisa zvakare sisitimu kuti itangezve kutenderedza maoko. Uye nekuti inotenderedza yakachinjika zvinhu, kusiana kwezvinhu (kusanganisira mazinga akasiyana e elasticity) harisi dambudziko.
Munzvimbo zhinji dzekugadzira maindasitiri uye zvimiro, vagadziri vari kutsvaga kuwedzera huwandu hwemafekitori pasi kuti kurerutsa pa-saiti kugadzira uye kusangana. Nekudaro, mutemo uyu haushande kana zvasvika pakugadzira matangi makuru ekuchengetera uye akafanana zvivako zvakakura, kunyanya nokuti basa rakadaro rinosanganisira kuoma kunoshamisa mukubata zvinhu.
Iyo roll-fed vertical swath inoshandiswa pasaiti inorerutsa kubata kwezvinhu uye inogonesa iyo yese yekugadzira matangi maitiro (ona fig. 2). Zviri nyore kutakura mipumburu yesimbi kuenda kunzvimbo yebasa pane kukungurutsa nhevedzano yemaprofile makuru mumusangano. Pamusoro pezvo, pa-saiti rolling zvinoreva kuti nyangwe matangi akakura edhayamita anogona kugadzirwa aine imwe chete vertical weld.
Kuve ne-on-saiti yakaenzana kunopa kuchinjika kwakawanda kwekuita kwesaiti. Iyo isarudzo yakajairika yekugadzira tangi pa-saiti, uko kushanda kwakawedzerwa kunobvumira vagadziri kuti vashandise macoil akatwasuka kugadzira matangi madhiri kana matangi pasi-pa-saiti, kubvisa kufambisa pakati pechitoro nenzvimbo yekuvaka.
Mupunga. 3. Mamwe vertical rolls akabatanidzwa mune-saiti tangi yekugadzira system. Iyo jack inosimudza iyo yakambokungurutswa kosi kumusoro pasina kushandisa crane.
Mamwe mashandisirwo epa-saiti anobatanidza vertical swaths kuita yakakura sisitimu, kusanganisira yekucheka uye welding mayunitsi akasanganiswa neakasarudzika jacks, kubvisa kudiwa kwe-on-saiti cranes (ona Mufananidzo 3).
Dziva rose rakavakwa kubva kumusoro kusvika pasi, asi maitiro anotanga kubva pakatanga. Heano mashandiro azvinoita: Mupumburu kana shizha rinodyiswa kuburikidza nemarora akachinjika masendimita mashoma kubva panofanira kunge paine tangi. Rusvingo rwunobva rwapinzwa mugwara rinotakura bepa parinopfuura nekutenderera kwese kwese kwetangi. Iyo vertical roll inomiswa, migumo inogurwa, yakabaiwa uye imwe yakamira seam inosungirirwa. Zvadaro zvinhu zvembabvu zvinosungirirwa kugoko. Zvadaro, jack inosimudza goko rakapetwa kumusoro. Dzokorora maitiro ekeke rinotevera pazasi.
Circumferential welds yakagadzirwa pakati pezvikamu zviviri zvakaputirwa, uye ipapo denga retangi rakagadzirwa panzvimbo - kunyange zvazvo chimiro chakaramba chiri pedyo nevhu, chete mabhomba maviri epamusoro akagadzirwa. Kana denga rapera, jacks inosimudza chimiro chese mukugadzirira goko rinotevera, uye maitiro anoenderera mberi-zvese pasina crane.
Kana kuvhiyiwa kwasvika padanho rakaderera, slabs anouya mukutamba. Vamwe vanogadzira matangi emumunda vanoshandisa mahwendefa ane 3/8 kusvika 1 inch gobvu, uye mune dzimwe nguva anotorema. Ehe, mapepa haapiwe mumipumburu uye anogumira pakureba, saka aya ezasi zvikamu zvichange zvine akati wandei vertical welds anobatanidza zvikamu zvepepa rakapetwa. Chero zvazvingaitika, uchishandisa vertical machines pasaiti, slabs anogona kuburutswa mune imwe kuenda uye akakungurutswa pane saiti kuti ishandiswe zvakananga mukuvaka tangi.
Iyi tangi yekuvaka sisitimu muenzaniso wekubata zvinhu zvinogoneka zvakawanikwa (zvishoma muchikamu) nekutenderera kwakamira. Ehe, senge chero imwe nzira, vertical scrolling haina kukodzera kune yega application. Kushanda kwayo kunoenderana nekugadziriswa kwekugadzirisa kwainogadzira.
Fungidzira kuti mugadziri anoisa isina-feed vertical swath yeakasiyana maapplication, mazhinji acho ari madiki dhayamita casings anoda pre-kupeta (kukotama inotungamira uye inoteedzera micheto yeworkpiece kuderedza isina kubhenda yakafuratira nzvimbo). Aya mabasa ane theoretically anogoneka pama vertical rolls, asi kufanokotama munzira yakatwasuka kwakaoma zvakanyanya. Muzviitiko zvakawanda, vertical rolling yehuwandu hukuru, inoda pre-kupeta, haina kukwana.
Pamusoro penyaya dzekubata zvinhu, vagadziri vakabatanidza kutenderera kwakamira kuti vadzivise simba rinokwevera zvinhu pasi (zvakare, kudzivirira kuchinjika mahombe asina kutsigirwa). Zvisineyi, kana kuvhiya kuchingobatanidza kupeta bepa rakasimba zvakakwana kuchengetedza chimiro charo panguva yese yekukungurutsa, hapana chikonzero chekukungurusa shizha iro rakatwasuka.
Zvakare, asymmetrical jobs (ovals uye mamwe maumbirwo asina kujairika) anowanzo kuumbwa zvakanyanya pahorizontal swaths, nerutsigiro rwepamusoro kana zvichidikanwa. Muzviitiko izvi, zvitsigiso hazvingodzivisi kudonha nekuda kwegiravhiti, zvinotungamira workpiece panguva yekutenderera kutenderera uye kubatsira kuchengetedza iyo asymmetrical chimiro cheiyo workpiece. Kuoma kwekuita basa rakadaro nepamusoro-soro kunogona kufuratira mabhenefiti ese eku scrolling yakatwasuka.
Pfungwa imwechete inoshanda pakukunguruka kwekoni. Makoni anotenderera anovimba nekukweshana pakati pema roller uye kudzvanywa kusiyanisa kubva kune imwe mugumo we roller kuenda kune imwe. Rongedza koni yakatwasuka uye giravhiti inowedzera kuoma. Panogona kunge paine zvisizvo, asi kune zvese zvinangwa uye zvinangwa, yakatwasuka koni yekukwenya haigoneki.
Kushandiswa kwemuchina-matatu-matatu ane dudziro geometry munzvimbo yakatwasuka zvakare kazhinji haigoneki. Mumichina iyi, iwo maviri epasi rolls anofamba akananga kune rimwe divi mune chero nzira, uku iyo yepamusoro roll ichichinjika kumusoro nekudzika. Aya magadzirirwo anobvumira michina kukotamisa yakaoma geometries uye roll zvinhu zvehukobvu hwakasiyana. Muzhinji, mabhenefiti aya haawedzerwe nekutenderera kwakatwasuka.
Paunenge uchisarudza mapepa emapepa, zvakakosha kuti uite tsvakiridzo uye yakanyatso tsvakiridzo uye kufunga nezvechinangwa chekugadzira kushandiswa kwemuchina. Vertical swaths ine mashandiro mashoma pane echinyakare akachinjika swaths, asi anopa zvakakosha mabhenefiti kana zvasvika pakushandisa kwakakodzera.
Vertical plate rolling machines inowanzove yakanyanya kukosha dhizaini, kuita uye dhizaini maficha pane yakachinjika ndiro yekutenderedza michina. Mukuwedzera, mipumburu yacho inowanzova yakakura kwazvo yekushandiswa, kubvisa kudiwa kwekubatanidza korona (uye mbiya kana hourglass effect inoitika muworkpiece kana korona isina kunyatsogadziriswa nokuda kwebasa riri kuitwa). Kana yakashandiswa pamwe chete nema unwinders, inogadzira zvinhu zvakatetepa kumatangi ese emusangano, kazhinji anosvika 21'6 ″ mudhayamita. Iyo yepamusoro yedhiyamita yakakura-yakaiswa tangi inogona kunge iine imwe chete yakatwasuka weld pane matatu kana kupfuura ndiro.
Zvekare, mukana mukuru wekutenderera wakatwasuka uri mumamiriro ezvinhu apo tangi kana ngarava inoda kuvakwa yakatwasuka nekuda kwekuita kwesimba rinokwevera zvinhu pazvinhu zvitete (kusvika 1/4 ″ kana 5/16 ″ semuenzaniso). Kugadzirwa kweHorizontal kunoda kushandiswa kwekusimbisa zvindori kana kudzikamisa zvindori kugadzirisa chimiro chakatenderera chezvikamu zvakapetwa.
Kubatsira chaiko kwema vertical rollers kuri mukubudirira kwekubata zvinhu. Iko kushoma kunyengedza kwaunoda kuita nemuviri, kashoma kukuvara uye kugadzirwazve. Funga nezvekudiwa kwakanyanya kwematangi esimbi asina simbi muindasitiri yemishonga, iyo iri kubatikana kupfuura kare. Kubata kwakashata kunogona kutungamira kumatambudziko ekushongedza kana zvakanyanya, kukuvadza kune passivation layer uye kusvibiswa kwechigadzirwa. Vertical rolls inoshanda pamwe chete nekucheka, welding uye kupedza masisitimu kudzikisa mukana wekunyengedza uye kusvibiswa. Kana izvi zvikaitika, vagadziri vanogona kubatsirwa nazvo.
