4U2U ipleyiti yebholiti yokusetyenziswa kushishino? 

Uyazi, xa umntu ebuza malunga ne-4U2U ye-bolt plate specs, ngakumbi kwizicelo zemizi-mveliso enzima, ithuku lam lokuqala kukucacisa: ngaba sithetha ngento enye? Kumava am, loo combo yealphanumeric - 4U2U - ayisiyiyo i-ASTM esemthethweni okanye ukutyunjwa kwe-ISO onokufumana isitampu kushicilelo. Yinto yangaphakathi, iprojekthi-ingqale, okanye imfutshane yomthengisi. Ndiyibonile iphuma kwii-RFQs ezivela kumacandelo athile, njengokuyila oomatshini abanzima okanye inkxaso ekhethekileyo yolwakhiwo. Ihlala ibhekisa kuqwalaselo oluthile: a ipleyiti yebholiti ekunokwenzeka ukuba yenzelwe i-M42 okanye iibholithi ze-ankile ezinobubanzi obukhulu ezifanayo, ezinobukhulu kunye nepateni yomngxuma ukuze itshatise umzobo wendibano ye-4U2U. Ukubhideka kuqala xa abantu beyiphatha njengenombolo yekhathalogu jikelele. Ayiyo. Incoko yokwenyani imalunga nokucacisa ukuba ileyibhile ithetha ntoni na kwizinto eziphathekayo, umthwalo, kunye nokufaneleka.

INyaniso eNgemva kweKhowudi: Izinto eziphathekayo kunye neMilinganiselo enguNdoqo

Ke, yintoni edla ngokungcwatywa kwi-4U2U spec? Ukususela kwimisebenzi endiyibambileyo, idla ngokukhomba ipleyiti etyebileyo, eyomelele kakhulu. Sihlala sijonga kwi-ASTM A36 okanye, ngokuqhelekileyo ngokuthwala umthwalo onzima, i-ASTM A572 yeBanga le-50 yentsimbi. I-U isenokuthetha iyunithi okanye iqela elithile lendibano. I-4 kunye ne-2 inokunxulumana ne-bolt yesangqa imilinganiselo okanye ubukhulu beplate ngeesentimitha-ndiye ndabona amacwecwe ajikeleze i-40mm ubukhulu abhalwe phantsi kweekhowudi ezifanayo. Inxalenye ebalulekileyo yipatheni yomngxuma webholiti: ubungakanani, isithuba, umgama womda. Ukusetyenziswa kwimizi-mveliso, i-diameter yomngxuma iqhele ukuba yi-2-3mm enkulu kune-bolt shank yokunyamezelana. Ukuba i-anchor yesiseko, ujonge kwakhona kwi-sleeve okanye iinkcukacha ze-washer. Ndikhumbula iprojekthi yesiseko secompressor apho ipleyiti ye-4U2U yabiza ubukhulu be-40mm, i-450mm yesikwere, enemingxuma emine engama-45mm kwisangqa se-350mm. Umzobo wawungacacanga, kodwa izibalo zoxinzelelo zazifuna imathiriyeli yeBanga lama-50.

Apho izinto ziba mbi kuxa ukuthengwa kwempahla kuphatha ikhowudi njengevangeli. Ndakhe ndafumana ibhetshi yeepleyiti ezizisiweyo ezihambelana nobukhulu kunye nobukhulu oburhabaxa, kodwa umthengisi usebenzise intsimbi enexabiso eliphantsi, isivuno esisezantsi, ecinga ukuba ipleyiti yipleyiti. Ukulingana bekulungile, kodwa ngexesha lovavanyo lomthwalo, sabona malunga nokuguquka. Sifunda ntoni? Ithegi yealphanumeric sisalatha nje. Kufuneka ubhekiselele kwiinkcukacha zoomatshini kunye nezinto eziphathekayo. Ukuba umzobo awuzidwelisi, kufuneka utyhale umva ukuze ucace. Ungaze ucinge.

Kulapho ukusebenza nomvelisi ofumana imeko yeshishini kubalulekile. Indawo efana I-Sunnian Zitai Festener Fishaner Comment Com. (https //wwww.ziitasteners.com), esekelwe kwisiseko esikhulu semveliso yecandelo laseTshayina e-Yongnian, e-Handan, ngokuqhelekileyo inamandla okuphatha la macwecwe aqhelekileyo, aphezulu. Ukusondela kwabo kwiindlela ezinkulu zezothutho kuthetha ukuba zimiselwe ubuninzi bezinto eziyimfuneko. Into ephambili kukubanika kungekuphela nje nge-label ye-4U2U, kodwa kunye nephakheji epheleleyo yobugcisa: ibakala lezinto eziphathekayo, ukuqina, ukunyamezela okuvumelekileyo (ngokukodwa ukubeka umngxuma, okubaluleke kakhulu ukulungelelaniswa kwe-multi-bolt), kunye nayiphi na i-pre-drilling efunekayo okanye i-chamfering.

Imigibe eqhelekileyo kwiFabrication kunye neFit-Up

Nokuba kukho iinkcukacha ezifanelekileyo, ukwenziwa kwezinto kunokwazisa imiba. Kula macwecwe angqingqwa, ukusika kwe-thermal kunye nokugrumba kunokuchaphazela izinto eziphathekayo ezijikeleze imingxuma. Ndihlala ndigxininisa kwingxelo yendlela evela kwivenkile. Ngaba kukusika iplasma, ukusika i-laser, okanye ukujezisa iprofayile? Kwimingxuma, ngaba zigrunjiwe, zibethelwe (akunakwenzeka ukuba i-40mm), okanye idikwe? Ukubetha kudala indawo enzima yokusebenza; ukugrumba kufuna ukutya okufanelekileyo kunye nesantya ukuphepha ukuqina. Kuhlobo lwe-4U2U yepleyiti emiselwe ukuthatha imithwalo eguquguqukayo, unokufuna ukucacisa umngxuma ogqityiweyo-ukubuyisela kwakhona kunokuba yimfuneko kwi-bolt echanekileyo.

Enye intloko esebenzayo ukuba tyaba. Ipleyiti le ngqindilili inokuba noxinzelelo lwangaphakathi ukusuka ekuqengqelekeni. Ukuba ayilunyanyisi uxinzelelo okanye ayilungiswanga ngokufanelekileyo, inokujika emva kokuba imingxuma isikiwe. Ndibone ipleyiti eyenziwe kakuhle yokusilela ukuhlala igungxulwe ebhedini yegrout ngenxa yokuba yayinesithsaba esifihlakeleyo. Ngoku, sihlala sikhankanya ukunyamezelwa komcaba phezu komhlaba wonke, hayi imiphetho. Yongeza iindleko, kodwa ithintela iiyure zokulungisa ukulungiswa kwindawo.

Emva koko kukho ukulungelelaniswa kunye neebholithi ngokwazo. Ipleyiti ye-4U2U ihlala ithetha ukusetyenziswa kweebholiti ezinzima ze-hex, mhlawumbi neentonga zeankile. Ukucocwa komngxuma kufuneka kuvumele ukungahambi kakuhle okuncinci kodwa kungabi mkhulu kangangokuba iwasha ayiwugubungeli. Oku sikufunde kabuhlungu kulwakhiwo lwenkxaso yokuthutha. Imingxuma yagrunjwa i-5mm oversize ukuze kube lula ukufaka, kodwa phantsi kwe-vibration, iibholithi zaqala ukujikeleza imingxuma. Ukulungiswa yayikukufakela iiwasha ezinkulu zesiko, nto leyo yayiliphupha elibi. Inkcazo kufuneka ilawule ngokungqongqo ubudlelwane bomngxunya ukuya kwibhonti.

I-Case in Point: I-Gearbox Mounting Retrofit

Makhe ndikunike umzekelo obambekayo. Besilungisa igearbox enkulu kumgangatho okhoyo wokusila. Ukunyuswa okudala kusetyenziswa ipleyiti ye-3U1U (bona, ngaphezulu kwale gama langaphakathi). I-gearbox entsha ibifuna i-interface ye-4U2U. Ucelomngeni yayingekokwenza ipleyiti entsha; ibiqinisekisa ukuba ipateni entsha yebholithi inokukhutshelwa ngokukhuselekileyo kwisiseko esikhoyo sekhonkrithi. I-4U2U spec ukusuka kwibhokisi yegiya ye-OEM idwelise kuphela imilinganiselo yepleyiti kunye neendawo zemingxuma.

Kuye kwafuneka sibuyisele umva-injineli yokulayisha idatha. Sabala i-shear kunye nomzuzu, ongazange uchaze kuphela ubukhulu beplate (sahamba kunye ne-42mm A572 Gr. 50) kodwa kunye nebakala leebhotshi ze-anchor-sagqiba ngeentonga ze-ASTM F1554 zeBanga le-105. Siphinde songeze inkcukacha eyona nto yayinqongophele: ijumbo hex washers ukusasaza ngcono umthwalo kwipleyiti. Ipleyiti yenziwe yivenkile eyafumana intsimbi ekrwada kwilitye lokusila elifana nelendawo yaseYongnian, iqinisekisa iipropati eziphathekayo. Sifunda ntoni? Ipleyiti licandelo nje elinye lenkqubo. Iinkcazo zayo azinantsingiselo ngaphandle kokuqwalasela iibholiti, isiseko, kunye nendlela yomthwalo.

Lo msebenzi ukwaqaqambisa ukubaluleka kokulungiswa komphandle. Ipleyiti ye-4U2U yayinokugqiba isikali sokusila. Ukuncamathela okufanelekileyo kwegrout, sicacise ukuqhushumba kwentsimbi ukuya kuthi ga kwintsimbi emhlophe qhwa kumphezulu ongezantsi. Oku kwakungekho kuyo nayiphi na ikhowudi, kodwa yayivela ekungaphumeleli kwangaphambili-ipleyiti eyayigqwala kwi-interface kwaye ivumela umswakama ukuba ungene, ubeka engozini i-grout.

Ngaphaya kwePlate: Ukonakala kunye neMfezeko yexesha elide

Kwiimeko ezingqongileyo zemizi mveliso, i-specs ihlala imisa kwi-dimensional kunye neemfuno zamandla. Kodwa kuthekani ngomhlwa? Kwisityalo sekhemikhali okanye indawo eselunxwemeni, iplate ye-carbon steel 4U2U ecacileyo ingaba lityala. Ndithethelele ukuntywila okushushu, kodwa loo nto yongeza ubukhulu kwimingxunya kwaye ifuna ukucofa okanye ukubuyisela kwakhona emva koko. Kwizicelo ezichaneke kakhulu, ungakhankanya inkqubo yokwaleka ye-corrosion-inhibitive. Lurhwebo phakathi kokuqina kunye nokuthembeka komda.

Olunye ulongamelo kukumakisha kunye nokulandeleka. Kwizicelo ezibalulekileyo, ipleyiti nganye kufuneka imakwe ngokusisigxina ngenombolo yobushushu, ibakala lezinto eziphathekayo, kunye ne-ID eyodwa. Oku kuvumela ukulandeleka emva kwisatifikethi sovavanyo lokusila. Linyathelo elilula eliye litsitywe ngokukhawuleza, kodwa lixabiseke kakhulu ukuba umbuzo uvela kwiminyaka kamva ngexesha lokuhlolwa okanye uhlalutyo lokungaphumeleli. Umenzi oyingcali uya kuqonda le mfuneko kwaye ayakhele kwinkqubo yabo.

Ukuyisonga: Indlela yobuGcisa

Ke, buyela kumbuzo wokuqala: Impendulo ayiyotafile ecocekileyo. Yinkqubo. Iqala ngokuphatha loo khowudi njengesikhokelo, hayi ingcaciso epheleleyo. Kuya kufuneka umbe okanye uchaze i-specs yemathiriyeli, ukunyamezelwa komda (ukunika ingqalelo ekhethekileyo kumngxuma wenyaniso kunye nesikhundla), ukuthambeka, iindlela zokuyila, kunye nokugqitywa komphezulu. Kuya kufuneka uyithathele ingqalelo njengenxalenye yenkqubo eneebholiti kunye nesiseko sezinto.

Ukubambisana nomenzi oqondayo la ma-nuances sisiqingatha sedabi. Bafanele babuze ulwazi olungaphelelanga, bangathatheli nje umyalelo. Nokuba ngaba ngumvelisi omkhulu onje Handan Zitai Fastener, kunye neengcambu zabo ezinzulu zokubonelela kwi-fastener hub yase-China, okanye ivenkile ekhethekileyo yendawo, ubuchule babo ekuguquleleni iikhowudi ezingacacanga zibe zizixhobo eziqinileyo, ezithembekileyo yinto oyihlawulayo ngokwenene.

Ekugqibeleni, injongo yiplate ehambelana ngokugqibeleleyo, ithwala umthwalo ngaphandle kwesikhalazo, kwaye ihlala ixesha elide njengoko isakhiwo esixhasayo. Ukufika apho kufuna ukujonga ngaphaya kweleyibhile ye-4U2U kunye nokwakha icwecwe elipheleleyo, elingacacanga. Lowo ngumahluko phakathi kwecandelo elingena kanye kunye necandelo elisebenza ngokwenene.
