Rivet

Ubabona kuyo yonke indawo, kodwa abantu abaninzi, kwanezinye iinjineli ezisanda kugqiba ukufunda, zicinga a rivet sisimumu nje sentsimbi oyityumzayo. Yimpazamo yokuqala leyo. Yinkqubo epheleleyo yoomatshini. Isitayela sentloko, i-shank material, uluhlu lokubamba-fumana enye engalunganga, kwaye indibano yakho iphazamisekile, kungekhona ngokukhawuleza, kodwa phezu kwemijikelezo yoxinzelelo. Oku ndakufunda kabuhlungu, kungekhona kwigumbi lokufundela, kodwa kumzi-mveliso oseHebei, ndibukele ibhetshi yealuminiyam. iirivets lusilele kuvavanyo lokungcangcazela ngenxa yokuba umntu othile ubachazele amandla okucheba kodwa akayihoyanga i-galvanic reaction kunye ne-substrate yentsimbi. Yinyani leyo.

I-Anatomy yeNdibaniselwano ethembekileyo

Makhe sichaze eyona nto ibalulekileyo. Iqala ngesethi. Ixesha lomgangatho wevenkile wofakelo rivet. A iseti elungileyo has a epheleleyo, intloko shop symmetrical, akukho iintanda eziphuma ikhefu mandrel. Ukuba ubona ikhefu elijijekileyo okanye intloko engekho embindini, isixhobo sinxibile okanye amandla angalunganga. Ndichithe iiyure kunye ne-calipers kunye ne-go / no-go gauges ukujonga iiseti ezivela kwi-automated feeders, kuba ukutenxa kwe-0.1mm kumngxuma ogrunjiweyo kunokuguqula umdibaniso oqinileyo ube ngumthombo we-squeaks kunye ne-rattles.

Ukukhetha izinto eziphathekayo ngomnye umgibe. Intsimbi engatyiwayo yokumelana nomhlwa? Ngokuqinisekileyo, kodwa iyasebenza-inzima. Kufuneka isixhobo womoya kunye umph ngokwaneleyo ukutsala mandrel ngaphandle kokuma. I-aluminiyam ethambileyo iirivets zilula kodwa zijonge amandla obambele—zinokukhululeka phantsi kokuhamba ngebhayisekile eshushu. Ndikhumbula iprojekthi yekhabhathi yomnxeba yangaphandle apho satshintsha ukusuka kwintsimbi yekhabhoni engenanto saya kwialloyi yealuminium. iirivets ngentloko etywiniweyo, nje ukulwa ne-condensation creep. Umtyholi kwezi nkcukacha zokusingqongileyo.

Emva koko kukho uluhlu lokubamba. Mhlawumbi eyona mpazamo ixhaphakileyo yokufuna. Ukubambelela bubunzima bubonke bezinto ozidibanisayo. Ukuba iimathiriyeli zakho ziyi-12mm ubukhulu, kwaye usebenzisa i rivet nge-6-10mm yokubamba, ayiyi kubumba ngokufanelekileyo. I-mandrel iya kuphuka phambi kokuba intloko yevenkile yenziwe ngokupheleleyo, ishiya i-joint eyimfama kodwa ebuthathaka. Ndigcina itshathi ifakwe kwidesika yam. Soloko udibanisa i-1.5mm kwisipakisho sakho esilinganisiweyo kwaye usondeze kweyona ndawo ikufutshane yokubamba ikhoyo. Ngumthetho olula othintela ukufowuna okuyingozi.

Ukubonelela kunye neNyaniso yoBonelelo

Kulapho ithiyori idibana khona negrinder. Unokuba ne-spec egqibeleleyo, kodwa ukuba ukungaguquguquki komboneleli wakho kucinyiwe, ugwetyiwe. Ndijongene namashumi, ukusuka kwiindibano zocweyo ezincinci ukuya kubavelisi abadibeneyo. Umahluko awusoloko ukwikhathalogu ecwebezelayo, kodwa kwinkqubo ye-QC. Iqabane elithembekileyo liyaqonda ukuba isiqhoboshi asiyompahla yorhwebo; yinxalenye ebalulekileyo.

Thatha indawo efana neSithili saseYongnian eHandan. Liziko, esona siseko sikhulu somgangatho wemveliso eTshayina. Ugxininiso lobuchwephesha kunye neziseko zoncedo lubalulekile. Inkampani esebenza apho, njengaye I-Sunnian Zitai Festener Fishaner Comment Com., ifakwe kuloo ecosystem. Indawo yabo ekufuphi nololiwe omkhulu kunye nemithambo yendlela ayingomgca nje kwiwebhusayithi (https //wwww.ziitasteners.com); iguqulela kwimpumelelo yolungiselelo lwemathiriyeli ekrwada kunye nempahla egqityiweyo ngaphandle. Xa ulawula i-inventri yangexesha lomgca wendibano, oko kufutshane kwi-Beijing-Guangzhou Railway kunye ne-expressways kubaluleke kakhulu kunomahluko omncinci wexabiso kwiwaka ngalinye.

Kodwa ukuba kwindawo eyiyo akuthethi ngokuzenzekelayo umgangatho olungileyo. Kufuneka ugqirha. Ndikhumbula uphicotho kumboneleli owabonisa iisampulu ezintle, kodwa iqashiso imveliso yabo engahambelani nobulukhuni mandrel. Isiphumo: iindawo zokuqhawula ezingalindelekanga ngexesha lofakelo. Kwafuneka siyilahle yonke imithwalo. Sifunda ntoni? Soloko uvavanya isampulu yemveliso evela kwisixa esikhulu, hayi isampulu yegolide esele ilungisiwe. Buza iziqinisekiso zabo zezinto eziphathekayo, idatha yabo yokutsala-uvavanyo. Umvelisi oyingcali, njengalowo ukhankanyiweyo, kufuneka abonelele le datha ngokulula, njengenxalenye yenkqubo yabo eqhelekileyo.

Izixhobo kunye neFactor Human

Eyona ilungileyo rivet ayinamsebenzi ngaphandle kwesixhobo esifanelekileyo. I-pneumatic, i-hydraulic, ibhetri-yombane? Nganye inendawo yayo. Ukuveliswa kwevolumu ephezulu kumgca, i-squeezer ye-pneumatic iyinkosi. Kodwa ukulungiswa kwebala okanye izithuba ezixineneyo, umtsalane olungileyo osebenza ngebhetri ngumsindisi wobomi. I-metric engundoqo kukutsala amandla kunye noyilo lwemihlathi. Umhlathi ogugileyo uya kumosha rivet intloko, ukubeka esichengeni ukuxhathisa i-corrosion kunye ne-aesthetics.

Ii-operators zezinye iinguqu. Nokuba nge-automation, umntu ulayisha i-hopper, umntu utshintsha imihlathi. Ukubaqeqesha ukuba baqonde isandi seseti elungileyo-i-pop epholileyo-kunye nembi-isithonga esibi-kubalulekile. Ndiphumeze esweni elula yomsindo kwimigca njengetshekhi esezantsi ye-QC. Kuyamangalisa ukuba kaninzi kangakanani umqhubi esiva ingxaki ngaphambi kokuba i-sensor ifake iflegi.

Ukugcinwa kwesixhobo akuxoxiswana. Itshekhi yemihla ngemihla yezihluzi zomoya zezixhobo ze-pneumatic, iishedyuli eziqhelekileyo zokuthambisa. Ndiye ndabona iseli yendibano yeedola ezingama-50,000 isihla ngenxa yokuba amanzi kwinqwelo-moya adle ivalve yokuqalisa isixhobo. I iirivets bezilungile; inkqubo ayiphumelelanga. Ngumdlalo weenkqubo.

Xa ii-Aplikheshini ziyalela uYilo

Masifumane ikhonkrithi. Kwi-architectural cladding, ujongene nokwandiswa kwe-thermal, ukuphakamisa umoya, kunye nobuhle. Apha, intloko yedome iirivets ziqhelekile, rhoqo ngepeyintiwe okanye i-anodized finish ukuze itshatise indawo yolawulo. Ucelomngeni kukutywina. Ufuna i rivet nge-washer ye-EPDM edibeneyo, kwaye kufuneka ulandele ulandelelwano oluthile lokufakela-iphaneli, i-sealant, iwasha, rivet—ukuthintela ukungena kwamanzi. Tsiba i-sealant, kwaye umema ukuvuza.

Thelekisa oko noomatshini abanzima. Cinga ngezishukumisi zomhlaba. Apha, konke kumalunga namandla apheleleyo kunye nokumelana nokungcangcazela. Ubukhulu obukhulu, intsimbi ephezulu iirivets, ehlala ifakwe ishushu (ubugcisa obufayo, ngokungafihlisiyo), yenza amajoyina asisigxina aphatha imithwalo yokothuka ngcono kuneebholiti ezininzi. Indlela yokungaphumeleli apha idla ngokudinwa kwi-shank, kungekhona intloko. Siza kwenza uhlolo olungena kwidayi kumalungu abalulekileyo ngexesha lolungiso.

Emva koko kukho ihlabathi elibiyelweyo le-elektroniki. Incinci, iyimfama iirivets kwi-aluminium okanye i-stainless, i-M3 okanye i-M4 ubukhulu. Inkxalabo yi-ESD kunye nokuphepha i-swarf. Awukwazi ukuba shavings metal ukusuka ikhefu mandrel ewela kwibhodi yesekethe. Olunye uyilo lusebenzisa isiphelo esivaliweyo iirivets ukuba ukutywina umngxuma ngokupheleleyo, eyongeza inqanaba lokhuseleko lokusingqongileyo. Licandelo elincinci elenza umsebenzi obalulekileyo.

I-Evolution kunye neNiche

I rivet ayimi. Ukuzigqobhoza iirivets (Ii-SPRs) ezisetyenziswa kunye nemipu ye-servo-electrical ziguqula iivenkile ze-auto body, ukujoyina iintsimbi ezingafaniyo ngaphandle komngxuma owenziwe ngaphambili. Yingxubuwa yokubetha ngenqindi kunye ne-riveting. Kodwa ifuna ulawulo olugqibeleleyo phezu kobunzima bezinto kunye nobukhulu bokugquma. Sayivavanya ngeprojekthi yesakhelo sebhasi kwaye kwafuneka sicofe kumkhosi kunye ne-stroke kangangeenyanga ukuze sifumane amakhonkco angaguqukiyo ngaphandle kokukrazula umaleko ongaphantsi kwegalati.

Enye i-niche yimfama yolwakhiwo iirivets. Ayizo pop rivets zikatatomkhulu wakho. Baye itshixiwe-in mandrels okanye ukwandiswa mechanical ukuba kusondela amandla bolt eqinileyo. Zisetyenziswa kwindawo ye-aerospace kunye nomzila kaloliwe, apho ufuna ukuqina kwecala elingaboniyo kodwa awukwazi ukulalanisa kwimfezeko. Iindleko ngumyalelo wobukhulu obuphezulu, kodwa kunjalo nenkqubo yokuqinisekisa. Ibhetshi nganye iyalandeleka.

Ngoko, oku kusishiya phi? Abathobekileyo rivet licandelo elichanekileyo elenza isiqhoboshi esilula. Impumelelo yayo ixhomekeke kunxantathu: iinkcukacha ezichanekileyo zesicelo, umgangatho wokwenziwa ongaguqukiyo osuka kumthombo okwaziyo, kunye nofakelo olulawulwayo olunezixhobo ezifanelekileyo. Ungayihoyi nayiphi na umlenze waloo triad, kwaye idibeneyo iya kukuxelela, ekugqibeleni. Ayisiyiyo eyona nxalenye ibukekayo yomsebenzi, kodwa ukuyilungisa kuko okwahlula indibano ekhohlakeleyo kwenye ehlala amashumi eminyaka. Yeyona nto ithathwayo.
