Umzobo 1. Ngethuba lokujikeleza kwindlela ethe nkqo, i-coil-fed, i-edge ehamba phambili "i-curls" phambi kwee-gowing rolls.I-edge esandul 'ukunqunyulwa elandelwayo iqhutywe kwi-edge ehamba phambili, ibethelwe kwaye ifakwe kwi-welded ukuze yenze igobolondo egobileyo. .
Wonke umntu okwintsimi yokwenziwa kwesinyithi mhlawumbi uqhelene noomatshini bokushicilela, nokuba yi-clamp yokuqala, i-three-roll double-clamp, i-three-roll translation geometry, okanye iindidi ezine-roll.Nganye inezithintelo kunye neenzuzo zayo, kodwa nazo banophawu olunye olufanayo: baqengqa amaphepha kunye namaphepha kwindawo ethe tye.
Indlela engaqhelekanga kakhulu ibandakanya ukuskrola ngokuthe nkqo.Njengezinye iindlela, ukuskrola ngokuthe nkqo kunemida yayo kunye neenzuzo.Ezi nzuzo zisoloko zisombulula ubuncinane omnye wale mingeni mibini. enye yindlela ephantsi yokuphatha izinto eziphathekayo.Ukuphucula zombini kunokuphucula ukuhamba komsebenzi kwaye ekugqibeleni kwandise ukukhuphisana kwabavelisi.
Itekhnoloji yokuqengqeleka ngokuthe nkqo ayiyonto entsha.Iingcambu zayo zibuyela kwiinkqubo ezimbalwa zesiko ezakhiwe kwiminyaka yoo-1970.Ngeminyaka yoo-1990, abanye abakhi bomatshini banikezela ngeemill zokuqengqeleka ezithe nkqo njengemveliso eqhelekileyo.Ubuchwephesha bamkelwe ngamashishini ahlukeneyo, ngakumbi intsimi yokuvelisa itanki.
Iitanki eziqhelekileyo kunye nezikhongozeli eziveliswa ngokuthe nkqo ziquka iitanki kunye nezikhongozeli zokutya nesiselo, ubisi, iwayini, ibhiya, kunye namashishini axuba amayeza;Iitanki zokugcina i-oyile ye-API;kunye namatanki adityanisiweyo ezolimo okanye ukugcinwa kwamanzi.Ukuqengqeleka ngokuthe nkqo kunciphisa kakhulu ukuphatha izinto;ngokubanzi ivelisa umgangatho ophezulu wokugoba;kwaye ukondla ngokufanelekileyo ngakumbi inqanaba elilandelayo lemveliso yokuhlanganisa, ukulungelelaniswa, kunye nokuwelda.
Enye i-advanteji ifumaneka apho amandla okugcina izinto eziphathekayo anqongopheleyo.Ukugcinwa ngokuthe nkqo kweebhodi okanye amashiti kufuna iinyawo ezisisikwere ezimbalwa kakhulu kuneebhodi okanye amaphepha agcinwe kwindawo ethe tyaba.
Qwalasela ivenkile eqengqa amaqokobhe (okanye “iindlela”) zamatanki amakhulu amakhulu kwiirola ezithe tyaba. , iqokobhe mhlawumbi lifuna ukuxhaswa ngezinto eziqinisayo okanye izizinzi, okanye lifuna ukujikeleziswa kwindawo ethe nkqo.
Ubuninzi obunjalo bokuphatha-iphepha lokutya ukusuka kwindawo ethe tye ukuya kwimiqulu ethe tye, ethi emva koko ikhutshwe kwaye ifakwe kwi-stacking emva kokuqengqeleka-inokudala imingeni eyahlukahlukeneyo yokuvelisa. Iishiti zityiswa kwaye ziqengqeleke ngokuthe nkqo, zincanyathiselwe, ze emva koko ziphakanyiswe ngokuthe nkqo ukuya kumsebenzi olandelayo.Xa uqengqeleka ngokuthe nkqo, iqokobhe letanki alixhathisi ubunzima kwaye ngoko ke alihli phantsi kobunzima balo.
Okunye ukuqengqeleka okuthe nkqo kwenzeka koomatshini abane-roll, ngakumbi kwiitanki zedayamitha ezincinci (ngokuqhelekileyo zingaphantsi kweenyawo ezi-8 ububanzi) eziya kuthunyelwa ezantsi kwaye zisetyenzwe kwicala elithe nkqo.Inkqubo yokuqengqeleka ezine ivumela ukuqengqeleka kwakhona ukuphelisa iiflethi ezingaguqukiyo ( apho imiqulu ibamba ipleyiti), ebonakala ngakumbi kumaqokobhe amancinci amancinci.
Iitoti ezininzi ziqengqeleka ngokuthe nkqo kusetyenziswa imiqulu emithathu, oomatshini bejiyometri yeekholethi ezimbini, kusetyenziswa izikhenkce zentsimbi okanye ukondla ngokuthe ngqo kwikhoyili (indlela eya isiba yinto eqhelekileyo). I-radius ye-enclosure.Balungisa ii-rollers zokugoba xa i-edge ehamba phambili yekhoyili idibene, kwaye emva koko ilungise kwakhona njengoko i-coil iqhubeka isondla. kwaye umqhubi uhambisa iirola ukuba zenze ukugoba okungakumbi ukuhlawula.
I-Springback iyahluka ngeepropati eziphathekayo kunye nohlobo lwekhoyili.I-ID yangaphakathi (ID) yekhoyili ibalulekile.Zonke ezinye izinto zilingana, i-coil ye-intshi engama-20. Xa kuthelekiswa nenxeba elifanayo lekhoyili ukuya kwi-intshi ezingama-26, i-ID inxeba ngakumbi kwaye ibonisa. i-rebound.ID enkulu.
Umzobo 2. Ukuskrola ngokuthe nkqo kuye kwaba yinxalenye ebalulekileyo yofakelo lwebala letanki.Usebenzisa i-crane, inkqubo ikholisa ukuqala ngekhosi ephezulu kwaye iqhubele phambili ukuya kwinqanaba elisezantsi.Qaphela i-weld enye ethe nkqo kwikhosi ephezulu.
Qaphela, nangona kunjalo, ukuba ukuqengqeleka kwembiza okuthe nkqo kwahluke kakhulu ekuqengqelekeni kwepleyiti etyebileyo ekuqengqelekeni okuthe tye.Kule yokugqibela, umqhubi uzama ukuqinisekisa ukuba imiphetho yomcu ihambelana ngokuthe ngqo ekupheleni komjikelo. iidayamitha azilungiswa lula.
Xa usenza iqokobhe letanki ngemiqulu ethe nkqo yekhoyili, umqhubi akanakuvumela ukuba imiphetho idibane ekupheleni komjikelo wokuqengqeleka kuba, ngokuqinisekileyo, iphepha livela ngqo kwikhoyili.Ngexesha lokuqengqeleka, iphepha linomphetho ohamba phambili, kodwa hayi Kwimeko yezixokelelwano, i-coil iqengqeleka kwisangqa esipheleleyo ngaphambi kokuba igobe imiqulu ize isikwe emva kokugqitywa (jonga umfanekiso woku-1) . yatyhalelwa kungqameko oluphambili, yaqiniselwa, yaze yadityaniswa ukwenza iqokobhe elilisongekileyo.
Ukugoba kwangaphambili kunye nokuqengqeleka kwakhona kwiiyunithi ezininzi ze-coil-fed azisebenzi, oku kuthetha ukuba imiphetho yabo ehamba phambili kunye ne-trailing inamacandelo okulahla ahlala ekhutshiwe (afana namacandelo e-flat angenakugoba kwi-non-coil-fed rolling). jonga i-scrap njengexabiso elincinci lokuhlawula zonke izinto zokuphatha ukuphumelela iiroli ezithe nkqo zibonelela ngazo.
Nangona kunjalo, abanye abaqhubi bafuna ukwenza ubuninzi bezinto abanazo, ngoko ke bakhetha inkqubo edibeneyo yokulinganisa i-roll.Ezi zifana ne-four-roll straighteners kwi-coil processing line, ivele iguqulwe ngaphezulu.Ulungelelwaniso oluqhelekileyo lubandakanya isixhenxe- kwaye ishumi elinesibini eliphakamileyo elisebenzisa udibaniso oluthile lokungenzi nto, ukulungelelanisa, kunye nokugoba imiqulu.I-straightener ayinciphisi kuphela icandelo lokulahla i-scrap kwigobolondo ngalinye, kodwa kwandisa ukuguquguquka kwenkqubo;oko kukuthi, inkqubo inokuvelisa kuphela iinxalenye eziqengqelekayo, kodwa kunye neebhilidi ezizicaba.
Itekhnoloji yokulinganisa ayinakuphinda iphinde iphinde iphinde iphinde ikhuphe iziphumo zeenkqubo zokulinganisa ezongeziweyo ezisetyenziselwa kumaziko enkonzo, kodwa inokuvelisa izinto ezisicaba ngokwaneleyo ukuba zinqunywe nge-laser okanye i-plasma.Oku kuthetha ukuba abavelisi banokusebenzisa iikhoyili ze-vertical rolling kunye nokusebenza kwe-flat cutting.
Yiba nomfanekiso-ngqondweni womsebenzi oqengqa iqokobhe lecandelo letanki ufumana umyalelo webhetshi yezikhewu zetafile yokusika iplasma.Emva kokuba eqengqele iqokobhe alithumele ezantsi, uqwalasela inkqubo ukwenzela ukuba umlinganisi angatyi ngokuthe ngqo kwindawo ethe nkqo. Kwindawo yoko, i-level ityisa izinto ezisicaba ezinokusikwa kubude obufunwayo, ukudala i-flat blank yokusika i-plasma.
Emva kokusika ibhetshi yezithuba ezingenanto, umqhubi uhlengahlengisa inkqubo ukuze aqalise kwakhona ukuqengqeleka amaqokobhe etanki.Kwaye ngenxa yokuba uqengqa imathiriyeli ecaba, ukuguquguquka kwezinto (kubandakanya amanqanaba ahlukeneyo e-springback) ayingomba.
Kwiindawo ezininzi zokwenziwa kwemizi-mveliso kunye nolwakhiwo, abavelisi bajolise ekunyuseni umthamo wokwenziwa kweevenkile ukwenza lula kwaye kube lula ukwenziwa kwentsimi kunye nokufakwa. Nangona kunjalo, ukuveliswa kwamatanki amakhulu kunye nezakhiwo ezinkulu ezifanayo, lo mgaqo awusebenzi, ngokukodwa ngenxa izinto ezimangalisayo zokusingatha imingeni ekhoyo kwimisebenzi enjalo.
Ukusebenza kwindawo yomsebenzi, iiroli ezithe nkqo zekhoyili zenza lula ukuphatha izinto kwaye zenze lula yonke inkqubo yokwenziwa kwetanki (jonga uMfanekiso 2). Kulula kakhulu ukuthutha ikhoyili yentsimbi ukuya kwindawo yomsebenzi kunokukhupha uthotho lwamacandelo amakhulu kwindawo yokusebenzela. Ukongezelela koko. , ukuqengqeleka kwisiza kuthetha ukuba neyona matanki inkulu yedayamitha inokwenziwa ngeweld enye ethe nkqo.
Ukuzisa i-level kwintsimi kuvumela ukuguquguquka okungakumbi kwimisebenzi yentsimi.Olu khetho oluqhelekileyo kwimveliso yetanki kwisayithi, apho ukusebenza okongeziweyo kuvumela abavelisi ukuba bakhe iitanki zeetanki okanye i-bottom kwi-site ukusuka kwikhoyili echanekileyo, ukuphelisa ukuthutha phakathi kwevenkile. kunye nendawo yomsebenzi.
Umzobo 3. Ezinye iiroli ezithe nkqo zidityaniswe kunye neenkqubo zokuvelisa itanki kwisiza.I-jack iphakamisa ikhosi egqitywe ngaphambili ukuya phezulu ngaphandle kwesidingo se-crane.
Eminye imisebenzi yentsimi idibanisa i-vertical rolls kwi-system enkulu-kuquka ukusika kunye neeyunithi ze-welding ezisetyenziselwa iijacks zokuphakamisa ezikhethekileyo-ukususa imfuno ye-crane kwi-site (jonga uMzobo 3).
Itanki iyonke yakhiwe ukusuka phezulu ukuhla, kodwa inkqubo iqala ukusuka emhlabeni ukuya phezulu.Nantsi indlela esebenza ngayo: Ikhoyili okanye ishiti ligqithiswa ngemiqulu ethe nkqo i-intshi nje ukusuka apho udonga lwetanki lusentsimini.Udonga lutyiswa emva koko Kwizikhokelo ezithwala iphepha njengoko lityiswa ngeenxa zonke kwisangqa setanki.Imiqulu ethe nkqo iyamiswa, iziphelo ziyasikwa, kwaye imithungo ethe nkqo yomntu ngamnye ibekwe kwaye idityaniswe.Indibano ye-stiffener idityaniswa kwiqokobhe. , Jack uphakamisa iqokobhe elisongiweyo phezulu.Phinda inkqubo kwiqokobhe elilandelayo ngezantsi.
Iiwelds ezijikelezayo zenziwe phakathi kwamacandelo amabini aqengqelekayo, kwaye amaqhekeza aphezulu etanki adityaniswa endaweni - ngelixa isakhiwo sasihlala sisondele emhlabeni kwaye kwenziwa amaqokobhe amabini aphezulu kuphela. ukulungiselela iqokobhe elilandelayo, kwaye inkqubo iyaqhubeka - konke ngaphandle kwesidingo se-crane.
Xa umsebenzi ufikelela kumgca osezantsi, iipleyiti ezityebileyo ziza kudlala.Abanye abavelisi betanki kwisiza basebenzise i-3/8 ukuya kwi-intshi yeepleyiti ezityebileyo, kwaye kwezinye iimeko zinzima ngakumbi.Kambe ke, amaphepha awakho kwifom yekhoyili kwaye angakwazi. kuphela ixesha elide, ngoko ke la macandelo asezantsi aya kuba neewelds ezininzi ezithe nkqo ezidibanisa amacandelo ephepha eliqengqelekayo.Kuyo nayiphi na imeko, ngoomatshini abathe nkqo kwisiza, amaphepha anokothulwa kwindawo enye kwaye asongwe kwisiza ukuze asetyenziswe ngokuthe ngqo kulwakhiwo lwetanki.
Le nkqubo yokwakha itanki ibonisa ukusebenza kakuhle kokuphatha okuphunyeziweyo (ubuncinci ngokuyinxenye) ngokuqengqeleka ngokuthe nkqo.Kakade, njengayo nayiphi na iteknoloji, ukuskrola ngokuthe nkqo akufumaneki kuzo zonke ii-apps.Ukufaneleka kwayo kuxhomekeke ekusebenzeni kakuhle okwenzayo.
Qwalasela umenzi ofakela umqulu othe nkqo ongena-coil-feed ukwenza imisebenzi eyahlukahlukeneyo, uninzi lwayo ngamaqokobhe amancinane anedayamitha afuna ukugoba kwangaphambili (ukugoba imiphetho ekhokelayo nelandelayo yesixhobo sokusebenza ukunciphisa iflethi engagotywanga). Ngokwethiyori kunokwenzeka kwimiqulu ethe nkqo, kodwa ukugoba kwangaphambili kwicala elithe nkqo kunzima kakhulu.Kwiimeko ezininzi, ukuqengqeleka ngokuthe nkqo kungasebenzi kakuhle kwinani elikhulu lemisebenzi efuna ukugoba kwangaphambili.
Ukongeza kwimiba yokuphatha izinto, abavelisi baye badibanisa imiqulu emi nkqo ukuze bagweme ukulwa nobunzima (kwakhona ukuphepha ukubethelwa kweendawo ezivaliweyo ezinkulu ezingaxhaswanga) .Nangona kunjalo, ukuba umsebenzi ubandakanya kuphela ukuqengqeleka kwebhodi eyomeleleyo ngokwaneleyo ukugcina imilo yayo yonke inkqubo yokuqengqeleka, emva koko iqengqeleke. ibhodi ngokuthe nkqo ayenzi ngqiqo kakhulu.
Kwakhona, umsebenzi we-asymmetric (ii-ovals kunye nezinye iimilo ezingaqhelekanga) ngokuqhelekileyo zenziwe ngokufanelekileyo kwimiqulu ethe tye, kunye nenkxaso ephezulu xa ufunwa.bakhokela umsebenzi ngemijikelo eqengqelekayo kwaye bancede ukugcina ubume be-asymmetric bomsebenzi.
Ingcamango efanayo iyasebenza kwi-conical rolling.I-cones eziqengqelekayo zixhomekeke kwingxabano phakathi kwee-roller kunye nomthamo ohlukeneyo woxinzelelo ukusuka kwelinye icala le-roller ukuya kwelinye.Ukuskrola ikhowuni ngokuthe nkqo, ubunzima bongeza ubunzima obungakumbi. kodwa kuzo zonke iinjongo kunye neenjongo, ukuqengqeleka kwekhowuni ngokuthe nkqo akunakwenzeka.
Ukusetyenziswa ngokuthe nkqo koomatshini bejiyometri yokuguqulela imiqulu emithathu nako akwenzeki ngokubanzi.Kwaba matshini, imiqulu emibini esezantsi ishukuma ekhohlo nasekunene kulo naliphi na icala;umqulu ophezulu unokuhlengahlengiswa phezulu naphantsi.Olu hlengahlengiso luvumela aba matshini ukuba bagobe iijometri ezintsonkothileyo kunye nezixhobo zokuqengqeleka ezinobunzima obuhlukeneyo.Kwiimeko ezininzi, ezi zibonelelo aziphuculwa ngokuskrola ngokuthe nkqo.
Xa ukhetha umatshini wokugoqa ipleyiti, kubalulekile ukuphanda kunye nokuqwalasela ukusetyenziswa kwemveliso ekujoliswe kuyo ngokucokisekileyo nangokucokisekileyo.
Xa kuthelekiswa noomatshini bokugoba bepleyiti ethe tye, oomatshini bokugoba bepleyiti ethe nkqo banoyilo olusisiseko, ukusebenza kunye neempawu zokwakha.Kwakhona, imiqulu idla ngokuba nobukhulu bomsebenzi ukuze isicelo sifake izithsaba (kunye neziphumo ezingqukuva okanye zehourglass ezenzeka kwizixhobo zokusebenza xa izithsaba zingekho ngokufanelekileyo. zilungelelaniselwe umsebenzi okhoyo).Xa zisetyenziswa ngokudityaniswa nezinto zokuthambisa, zenza into ebhityileyo yetanki yevenkile iphela, ngokuqhelekileyo ingabi ngaphezu kwe-21 iinyawo 6 i-intshi ububanzi. Amatanki afakwe kwibala elinodayamitha engaphezulu kakhulu anokuveliswa. ngeweld enye ethe nkqo kuneephaneli ezintathu okanye ngaphezulu.
Kwakhona, inzuzo enkulu yokuqengqeleka ngokuthe nkqo kukuba itanki okanye isikhongozeli kufuneka sakhiwe ngendlela ethe nkqo ngenxa yempembelelo yomxhuzulane kwizinto ezibhityileyo (umzekelo, ukuya kuthi ga kwi-1/4 okanye 5/16 intshi). ukusetyenziswa kweendandatho zokuqinisa okanye ukuzinzisa ukugcina imilo ejikelezileyo yecandelo eliqengqelekayo.
Inzuzo yokwenyani yeeroli ezithe nkqo kukuphathwa kakuhle kwempahla.Amaxesha ambalwa indawo ebiyelweyo ifuna ukuphathwa, kunqabile ukuba yonakaliswe kwaye iphinde isetyenziswe.Qwalasela imfuno ephezulu yamatanki ensimbi engenasici kushishino loxubo mayeza, ngoku oluxakeke kakhulu kunangaphambili. .Ukuphathwa kakubi kunokukhokelela kwimiba ye-cosmetic okanye, ngakumbi, i-passivation layer ediliza kwaye idale imveliso engcolileyo.Ii-rolls eziqinileyo zisebenza ngokuhambelana nokusika, ukuthunga kunye nokugqiba iinkqubo zokunciphisa ukuphatha kunye namathuba okungcola.Xa oku kwenzeka, abavelisi bayavuna. iinzuzo.
I-FABRICATOR yeyona magazini iphambili kuMntla Melika yokwenziwa kwesinyithi kunye neshishini lokwenziwa kwemveliso.Imagazini ibonelela ngeendaba, amanqaku obugcisa kunye neembali zamatyala ezenza ukuba abavelisi benze imisebenzi yabo ngokufanelekileyo.IFBRICATOR ibisebenzela ishishini ukusukela ngo-1970.
