Ubona 'ukuzomba' kwiphepha elithile kwaye ucinge ukuba yonke into imalunga nenqaku lokubhola. Kodwa ngeenguqu zentloko engqukuva, sisiqingatha kuphela sebali. Umdlalo wokwenyani ukwidizayini yentloko edibana nefom yentambo kunye neflange-okanye ukungabikho kwayo. Uninzi lwabafana luyalela ezi zinto zicinga ukuba ziziintloko zepani nje nge-drill bit encanyathiselwe, kwaye emva koko bayazibuza ukuba kutheni befumana i-spin-out kwi-thinner gauge gauge steel okanye ukuqhekeka kwi-composites ezithile. Kukudityaniswa kokulindela kunye nobunjineli.

Umsebenzi wokwenyani weNtloko ayikuko nje ukuJonga Round

Loo nto igudileyo, ilawulwa intloko engqukuva iprofayile ikhona ngesizathu esingaphaya kwenkangeleko egqityiweyo. Kumsebenzi wokugquma kunye nokunciphisa, iprofayili ephantsi, i-radiused edge ayinakwenzeka ukuba ibambe okanye i-snag. Kodwa eyona nto ibalulekileyo ngumgangatho wokuthwala. Intloko engqukuva eqhelekileyo inendawo encinci yokuthwala phantsi kwedome xa ithelekiswa nentloko yewasha yeheksi. Oku kugxininisa amandla okubamba kwisangqa esincinane. Kulungile kwizicelo ezininzi, kodwa yinkcukacha ekufuneka uphendule ngayo. Ukuba uqhubela kwinto ethambileyo okanye enqabileyo, njengamapaneli athile e-fiberglass okanye i-aluminium encinci ngaphandle kwe-washer exhasayo, unokwenza lula ukugqithisa i-torque kunye ne-dimple okanye uqhekeze izinto. Ndiyibonile isenzeka amaxesha amaninzi kunokuba ndikwazi ukubala kwimisebenzi ye-retrofit apho i-spec yayingacacanga.

Apha kulapho injongo yoyilo lomenzi ingena khona. Ezinye iibrendi, ezifana nezo zisuka I-Sunnian Zitai Festener Fishaner Comment Com., bahlala benikezela nge-undercut encinci okanye indawo ebanzi yokuthwala kwiimodeli zabo ezijikelezileyo zentloko ngokukodwa kwi-sheet metal applications. Lutshintsho oluchuliweyo oluqaphela kuphela xa ulungelelanisa izikrufu ezintlanu ezahlukeneyo ezivela kubaboneleli abohlukeneyo. Le isuka kuZitai inokuba neradiyasi ebanzi eyimilimitha phantsi kwentloko, nto leyo eguqulela ekucuthekeni okubalulekileyo komthwalo wamanqaku. Ufumana ezi nuances xa ukhangela kwingingqi efana neYongnian, Hebei-isiseko semveliso sithetha ukuba babone zonke iindlela zokusilela kwaye baphindaphinda.

Kwaye makhe sithethe ngokuqhuba. Intloko engqukuva ngokuqhelekileyo ithatha iPhillips okanye iPozi drive. Kwintsimi, kunye nomqhubi wempembelelo, i-cam-out ngumngcipheko wokwenene, ngakumbi ukuba ubulukhuni be-screw abuhambelani ne-drill point's aggression. Ukungaphumeleli kwekhefu lokuqhuba kumathuba ambalwa okugqibela kuyacaphukisa. Yiyo loo nto xa ndiqhuba umthamo ophezulu, ndingqiyama entlokweni engqukuva ngePozi drive ukuba ikhona-isebenza ngcono phantsi kwetorque. Iwebhusayithi https //wwww.ziitasteners.com idwelisa rhoqo uhlobo loqhubo ngokucacileyo, into encinci kodwa ebaluleke kakhulu yokungafihli nto egcina ixesha.

Indawo yeDrill: Apho ithiyori idibana nesinyithi

Le yintliziyo yomphefumlo izikrufu zokuzenzela umsebenzi, kwaye awuqondwa kakuhle. Inkqubo yamanani (njengo 3, 5 point) ayingobude nje; imalunga nobungqingqwa bezinto ezicetyiweyo kunye nobulukhuni. Inqaku eli-3 linokuthi lihambe ngentsimbi ye-20-gauge kodwa liya kusokola kwaye lifudumale kakhulu kwi-14-gauge, liguge phambi kwexesha kwaye lisilele ukwenza umsonto ofanelekileyo. Impazamo eqhelekileyo kukugrumba ngaphezulu-usebenzisa inqaku elenzelwe izinto ezityebileyo kwiphepha elincinci. Idala umngxuma omkhulu kakhulu, imisonto ayizibandakanyi ngokupheleleyo, kwaye ufumana uqhagamshelo olubuthathaka, olungenamsebenzi olunokusebenza lukhululwe kukungcangcazela.

Ndifunde oku ngendlela enzima kwiprojekthi ye-ductwork kwiminyaka eyadlulayo. Sasinebhetshi yezikrufu ezineengongoma ezi-5 ezinobundlobongela zegeyiji enzima, kodwa sasisebenza ngezinto ezikhaphukhaphu. Izikrufu zangena ngokukhawuleza, ngokuqinisekileyo, kodwa itywina yayisoyikeka. Umoya uvuza kuyo yonke indawo. Kuye kwafuneka sibuyisele umva ngamnye kwaye sitshintshele kwindawo ecocekileyo, emfutshane. Inkunkuma emsebenzini yayisisifundo. Ngoku, ndihlala ndibhekisa kwisitayile senqaku kunye nobukhulu bokwenyani. Abavelisi kwiziseko eziphambili zemveliso banale datha phantsi; iikhathalogu zabo zidla ngokuba ne-gauge-to-point guide. Ayikokuthengisa kuphela.

Uyilo lwefluti nalo lubalulekile. nembande zimke nomzi. Ukuba azinzulu kakhulu okanye i-engile engalunganga, i-swarf ipakisha emngxunyeni, inyusa ubushushu kunye nokukhuhlana. Uza kubona umsi, uve ukukhala okuphezulu, kwaye isikrufu siya kubamba. Ulungile self-drilling screw ivelisa iitshiphusi ezincinci ezigoqiweyo. Ukuba ufumana uthuli oluyimpuphu, ijometri okanye ubunzima bezinto eziphathekayo akulunganga. Ukujonga isampuli ngokuqhuba kwisiqwenga esilahliweyo sesona sixhobo somsebenzi asiyonto ethethwayo. Luvavanyo lwemizuzu emihlanu oluthintela ukufowunelwa kwendawo yonke.

Izinto eziphathekayo kunye noKwaleka: Izikhuselo ezingabonakaliyo

Awukwazi ukuthetha ukusebenza ngaphandle kokuthetha ukuba isikrufu senziwe ngantoni kwaye sinxitywe ngaso. Kwiindawo ezininzi zangaphandle okanye ezonakalisayo, i-zinc plating ayizukuyinqumla. Ndikhankanya i-stainless okanye umgangatho we-mechanical plating yemisebenzi yohlahlo lwabiwo-mali kodwa ehlala ixesha elide. Kodwa nantsi i-nuance kunye intloko engqukuva izikrufu zokuzibhora: Ubunzima bokugquma. Ukugquma okungqindilili okufana nentsimbi eqhelekileyo yokudipha kunokuphazamisana nobukhali bendawo yokubhora kwaye ide izalise iifluti kancinci, inciphisa ukusebenza kakuhle. Iyakwazi ukwakha phantsi kwentloko, itshintshe iimpawu ze-clamp.

Ukusebenza okuhambelanayo, ndikhetha izikrufu ezine-zinc-aluminiyam yokwaleka i-flake okanye ukugqiba okucekethekileyo, okuqinileyo kwe-electroplated. Zikhusela kakuhle ngaphandle kokongeza ubukhulu obukhulu. Indawo yomthengisi ingabonisa ubuchule babo. Ukuba kufuphi neendlela ezinkulu zezothutho, njengeBeijing-Guangzhou Railway kunye neendlela zokuhamba, njengoko iZitai zinjalo, zihlala zithetha ukuba zilungiselelwe ukubonelela ngomthamo kumashishini aneempawu ezingqongqo zomhlwa-njengeemoto okanye ukuvelisa izixhobo zombane. Ulawulo lwenkqubo yabo yokwaleka luthande ukuhambelana kakhulu, yiloo nto oyifunayo xa uodola amaqhekeza angama-50,000.

Kwaye intsimbi engundoqo ibalulekile. Kukulingana phakathi kobunzima bendawo yokubhola kunye ne-ductility ye-shank. Kunzima kakhulu, kwaye isikrufu sinokukrazuka phantsi koxinzelelo olusecaleni. Ithambile kakhulu, kwaye inqaku liyajikeleza. Abavelisi abalungileyo basebenzisa insimbi yekhabhoni ephakathi, ephathwa ngokushushu ngokuchanekileyo. Ngamanye amaxesha unokuxela ngekhefu. I-fracture brittle yigranular kwaye igqamile; i-ductile enye ikrazukile ngakumbi. Yi-forensic, kodwa ikuxelela into engahambi kakuhle.

Umbuzo weFlange: Ukuba Unayo okanye Ungabinayo

Olu lukhetho lomntu oluba ngumthetho osekelwe kwisicelo. Intloko engqukuva eqhelekileyo ihlala phezu kwezinto. Intloko engqukuva eneflange inewasha eyakhelweyo. Loo flange isasaza umthwalo ngokumangalisayo. Ukukhusela amanzi okanye ukutywinwa kwezicelo-cinga ukudibanisa i-rubber ye-roofing membrane kwi-steel deck-i-flange inyanzelekile. Yenza itywina loxinzelelo oluhambelanayo. Ngaphandle kwayo, uthembele kumphezulu omncinci wedome, kwaye ngokuqinisekileyo uya kufumana ukuvuza.

Kodwa i-flange yongeza ubude kunye nobunzima. Kwiindawo ezixineneyo okanye apho iprofayili egungxulwayo ngokwenyani ifuneka ngenxa yezizathu zobuhle okanye zokhuseleko (akukho kurhwaphiliza), intloko engqukuva eyithafa ngukumkani. Isitshixo kukuba ungaze ufake enye endaweni kwenye ngaphandle kokubala kwakhona umthwalo we-clamp kunye nemfuneko yokutywinwa. Ndakha ndabona iqela labasebenzi besebenzisa iintloko eziphokopheleyo ukuqhoboshela intsimbi kwisakhiwo sentsimbi kuba yayiyiloo nto babenayo elorini. Isinxibo sahlala sinebhongo, singahlali kakuhle, kwaye sikhangeleka sisoyikeka. Umphathi watyhola izikrufu, kodwa ibe yimpazamo yokhetho.

Xa ubrawuza ikhathalogu, njengaleyo unokuyifumana kwindawo enkulu yomenzi, lo mahluko ubalulekile. Baza kuludwelisa njengezinto ezahlukeneyo. Inkampani esesona siseko sikhulu somgangatho wemveliso iya kuba nazo zombini, kwaye kusenokwenzeka ukuba zonke iinguqulelo phakathi, kuba ziceliwe ziinjineli ezisombulula iingxaki ezithile.

Entsimini: Yintoni engakuxeleliyo iPhepha eliKhethekileyo

Isantya siyabulala. Ngomqhubi onempembelelo, kuyahenda ukuqhuba isikrufu kwi-throttle epheleleyo. Kodwa kwifom yentambo ecocekileyo kunye nokuphepha ukwakhiwa kobushushu, kufuneka uvumele indawo yokucoca isebenze. Qala ngoxinzelelo oluqinileyo kunye nesantya esiphakathi de inqaku lingene ngokupheleleyo kwaye uziva ukuba intambo yokubandakanya iqala, ngoko unako ukunyusa i-RPM ukuze uhlale intloko. Ukuba umqhubi ubethelela kude ekupheleni, mhlawumbi ukhulula imisonto emngxunyeni.

Elinye inqaku lentsimi: imingxuma yokulinga. Ixesha ukuzigrumba kuthetha ukuba awuyidingi. Kwaye uninzi lomsebenzi wentsimbi ukuya kwintsimbi, awukwenzi. Kodwa xa ujongana nezixhobo ezicwangcisiweyo - masithi, intsimbi phezu komthi, okanye nge-rubber gasket - umngxuma omncinci wokulinga kwinqanaba eliphezulu unokuthintela isikrufu ukuba singahambi okanye izinto ezithambileyo zingakrazuki. Bubuchule obuxutyiweyo obungekho kwincwadana yemigaqo, kodwa buyasebenza.

Ekugqibeleni, ukukhangela. Ukungqinelana yinto yonke. Ukufumana umenzi onokuhambisa imveliso efanayo, kunye ne-metallurgy efanayo kunye ne-coating, i-batch emva kwe-batch, ixabiseke ngaphezu kokugcina isiqingatha sepesenti kwiyunithi nganye. Inzuzo yolungiselelo lomboneleli obekwe kwindawo esembindini enoqhakamshelwano olugqwesileyo lwezothutho ayinakubaxwa. Kuthetha amaxesha okukhokela athembekileyo kunye nolungiselelo olulula kwii-odolo ezinkulu. Xa ixesha leprojekthi yakho liqinile, ukwazi ukuba izikrufu zakho ziya kufika kwishedyuli ukusuka kwindawo efana nesiseko sikaHandan Zitai luhlobo lolawulo lomngcipheko. Awuthengi nje into yokuqhobosha; uthenga ukuqikelela.
