Ibanga 8.8 I-Black Oxide Hex Socket Izikulufa Zekhanda Lekhanda-Ukubuka Konke Kwezobuchwepheshe Kokuvikela Ukugqwala kanye Nomklamo Wekhanda 

2. IBanga lesi-8.8 I-Black Oxide Finish: Ukuvikela Ukugqwala

2.1 Iyini I-Black oxide?

I-Black oxide, ebizwa nangokuthi i-blackening, ingxube yokuguqulwa kwamakhemikhali ekhiqizwa ngokuphendula ubuso bensimbi ene-alkaline oxidizing emazingeni okushisa aphakeme (imvamisa engu-140 kuya ku-150 degrees Celsius). Ngokungafani nezingubo ezine-electroplated ezifana ne-zinc noma i-Dacromet, ebeka ungqimba lwensimbi oluhlukile phezu kwe-substrate, i-oxide emnyama iguqula ungqimba oluphezulu lwensimbi ngokwayo lube yi-magnetite (Fe3O4), i-iron oxide emnyama ezinzile. Umphumela uba indawo encane, emnyama-emnyama eba yingxenye ebalulekile ye-fastener kunesendlalelo se-add-on.

2.2 Inqubo ye-Black oxide

Inqubo ejwayelekile ye-black oxide yezinsimbi zeBanga lesi-8.8 ibandakanya lezi zigaba ezilandelayo:

Ukwehlisa amafutha kanye nokuhlanza i-alkaline ukususa amafutha, uketshezi lokusika, nokungcola kwezitolo.

I-Acid pickling ukususa noma yisiphi isikali esingaphezulu noma ukugqwala okukhanyayo.

Ukucwiliswa kubhavu oshisayo one-alkaline-oxidizing (cishe amadigri angu-141 Celsius), lapho ungqimba lukazibuthe lwakha khona emizuzwini eyi-10 ukuya kwengama-20.

Ukuhlanzwa nokuvala ngowoyela ovimbela ukugqwala noma i-wax, egcwalisa ungqimba lwe-oxide ngesivimbo se-hydrophobic.

2.3 Izimpawu Zokumelana Nokugqwala

Ngokwaso, ungqimba lwe-oxide emnyama luncane (cishe ama-micrometer angu-0.5 kuya ku-1.5) futhi lunama-porous, okusho ukuthi lunikeza kuphela ukumelana nokugqwala okulinganiselwe uma kuqhathaniswa ne-zinc plating noma i-hot-dip galvanizing. Kodwa-ke, uma kuhlanganiswe namafutha noma i-wax eyengeziwe yokuvimbela ukugqwala, ukunamathela kufinyelela ukumelana nesifutho sikasawoti esimaphakathi cishe amahora angu-24 kuya kwangu-96, kuye ngekhwalithi ye-sealant. Leli zinga lokuvikela lanele endaweni engaphakathi, elawulwa yisimo sezulu, noma indawo enokugqwala kancane lapho isibophelelo singevezwanga kumswakama oqondile noma isifutho sikasawoti isikhathi eside.

2.4 Izinzuzo kanye nemikhawulo

1.Ushintsho lwe-dimensional enguziro: Ngenxa yokuthi ungqimba lwe-oxide lungaphansi kwama-micrometer angu-2 ubukhulu, i-oxide emnyama ayishintshi ukubekezelela intambo. Izibophelelo zeBanga lesi-8.8 zigcina ukulingana kwazo kwangempela kweSigaba 6g, okwenza okokunamathela kube kuhle ukuze kuhlanganiswe ukunemba lapho ukuphazamiseka kwentambo kufanele kugwenywe.

2.Ingabizi: I-Black oxide ingenye yezindlela zokwelapha ezitholakalayo, ezishibhile kakhulu kune-zinc-nickel plating, i-Dacromet, noma ezinye izindlela zensimbi engagqwali.

3.Ayikho i-hydrogen embrittlement: Ngokungafani ne-electroplating, inqubo ye-oksidi emnyama ayikhiqizi igesi ye-hydrogen, iqeda ingozi ye-hydrogen embrittlement. Lokhu kubalulekile kuma-fasteners eBanga lesi-8.8 asebenza emazingeni aphezulu okucindezeleka.

4.Isikhalo sobuhle: Isiphetho esimnyama esifana ne-matte-black sinikeza ukubukeka okuhlanzekile, okuphrofeshinali okuhlangana nokuhlanganisa okunombala omnyama futhi kunciphisa ukuxhopha kokukhanya.

5.Umkhawulo - Ukumelana nokugqwala okulinganiselwe kwangaphandle: I-Black oxide ayifanele indawo yangaphandle, yasolwandle, noma egqwala kakhulu. Ngezicelo ezinjalo, i-Dacromet, i-zinc-nickel plating, noma insimbi engagqwali kufanele icatshangelwe.

3. I-Cylindrical Head ene-Hex Socket Drive

3.1 Uhlolojikelele lwedizayini

Ikhanda eliyisilinda (elivame ukubizwa ngokuthi i-socket head cap screw head noma i-DIN 912 / ISO 4762 head) linomumo oyisilinda oyisicaba onesokhethi ene-hexagonal ephakathi nendawo. Ububanzi bekhanda ngokuvamile bucishe buphindwe izikhathi ezingu-1.5 ubukhulu bentambo yokulinganisa, futhi ubude bekhanda bucishe buphindwe izikhathi ezingu-0.6 kuya ku-1.0 ubukhulu be-shank, kuye ngosayizi. Le geometry inikeza indawo enkulu yokuthwala ngaphansi kwekhanda ngenkathi igcina iphrofayili iyonke ihlangene futhi iphansi.

3.2 Izinzuzo ze-Cylindrical Head Design

Amandla okugoqa aphezulu: Ikhanda eliyisilinda lihlinzeka ngendawo yokuthwala enkulu kunemiklamo yekhanda le-countersunk noma yezinkinobho, isakaza umthwalo wokubopha endaweni ebanzi futhi inciphisa ingozi yokuhlehlisa phezulu noma ukulimala kucezu lokusebenza.

Izinyathelo eziqinile: Ngenxa yokuthi ikhanda lihlala phezu kwendawo kunokuba lishiswe, ikhanda eliyisilinda lidinga imbobo elula noma imbobo ethenjiwe. Akudingeki ukusebenza komshini wokubala, ukwenza ukukhiqiza kube lula.

Ukufakwa okuguquguqukayo noma okunyusiwe: Ikhanda lingafakwa ngokuguquguquka nendawo engaphezulu (uma uhlelo lokusebenza livumela ikhanda eliphakanyisiwe) noma lihlehliselwe ku-counterbore ukuze liqedwe ngokuphelele, linikeze ukuguquguquka komklamo.

Ukubukeka okuhlanzekile: Ikhanda eliyisilinda elibushelelezi linikeza ukubukeka okuhlanzekile, okufanayo okuthandwa ngobuhle emishinini, ekusetshenzisweni kwamathuluzi, nakugesi wabathengi.

3.3 Izinzuzo ze-Hex Socket Drive

I-hexagonal socket (Allen) drive iyisixhumi esibonakalayo esichazayo sesikulufu se-socket head cap. Ukhiye we-Allen hex (wrench) ubamba indawo yokuphumula enamaphuzu ayisithupha, idlulisa itorque ukushayela isikulufu. Lolu hlelo lokushayela lunikeza izinzuzo ezimbalwa ezihlukile ngaphezu kwe-hex yangaphandle, i-Phillips, noma amadrayivu afakiwe:

Ukudluliswa kwetorque ephezulu: Isokhethi ye-hex yangaphakathi ingamelana ne-torque ephakeme kakhulu kune-Phillips noma amadrayivu afakiwe, okuvumela ukuqiniswa okuthembekile kumanani aphezulu okulayisha kuqala adingekayo kuzibophelelo zeBanga lesi-8.8 (kufika ku-80% womthwalo wokuqinisekisa emajoyintini abalulekile).

Ukumelana ne-Cam-out: Ngokungafani namadrayivu e-Phillips aklanyelwe ukuphuma (ukuyeka) ngaphansi kwe-torque ephezulu, isokhethi ye-hex igcina ukubandakanyeka okugcwele, inciphisa ingozi yokushelela kwethuluzi kanye nokulimala kwekhanda.

Ukufinyelela kwephrofayili ephansi: Ukhiye we-hex usondela ukusuka phezulu (inkomba ye-axial), okuvumela ukufakwa ezindaweni ezivalekile lapho isikrufu singakwazi ukufinyelela khona sisuka eceleni. Lokhu kubaluleke kakhulu emibuthanweni yemishini eminyene.

Ingcuphe yokukhumula encishisiwe: Indawo enkulu yokuxhumana phakathi kokhiye we-hex nezindonga zesokhethi isabalalisa ingcindezi ngokulinganayo, inciphisa ithuba lokuguquguquka kodonga lwesokhethi noma ukuhlubula, ngisho nangemva kokuphinda ukufakwa nokususa imijikelezo.

4. Izicelo Ezijwayelekile

Izikulufu zekhanda lekhanda lesokhethi ye-oxide ye-oxide ye-oxide ye-8.8 zisetshenziswa kulo lonke uhla olubanzi lwezimboni lapho amandla aphakathi nendawo aphezulu, ukuvikelwa kokugqwala kwangaphakathi, nokufinyelela kokuhlanganisa okuhlangene kuyadingeka:

Ukwenziwa kwemishini nemishini: Izibasi zenjini, izindlu zamabhokisi kagiya, ama-pump assemblies, nokuxhumana kohlaka lwesakhiwo.

Ezezimoto (izingxenye zangaphakathi nezingaveziwe): Izingxenye zedeshibhodi, amafreyimu ezihlalo, abakaki bangaphakathi, nezinto ezingaphansi kwe-hood evikelekile ekuchayekeni kwesimo sezulu esiqondile.

Amathuluzi nezakhiwo: Izisekelo zesikhunta, ama-jig ne-fixture assemblies, namasethi okufa lapho ukugoqa okunembile nokuqaqa okuphindaphindiwe kuvamile.

Ama-elekthronikhi nezinto ezivalekile: Izinto zokusebenza ezifakwe kwi-rack, amabhokisi okuhlangana kukagesi, namaphaneli okulawula lapho kukhethwa khona umbala omnyama ohlanzekile kanye nekhanda eliphansi.

Ifenisha nehardware yezakhiwo: Amajoyinti efenisha emodulayo, izitendi zemibukiso, nokufakwa kwezakhiwo zangaphakathi.

5. Isiphetho

Izikulufu zekhanda lekhanda lesokhethi ye-oxide ye-oxide hex emnyama zimelela ikhambi lokubopha elilinganisele kahle elibhekana nezidingo ezimbili ezibalulekile zobunjiniyela ngesikhathi esisodwa. Ukuqedwa kwe-oxide emnyama kunikeza umgoqo wokugqwala ozacile, ozinze ngohlangothi we-hydrogen-embrittlement-free, owongayo futhi ongaguquguquki ngokubonakalayo. Nakuba ukumelana nokugqwala kwayo kunomkhawulo uma kuqhathaniswa nezingubo ze-premium ezifana ne-Dacromet noma i-zinc-nickel, ingaphezu kokwanele indawo yasendlini neyonakalise kancane. Ikhanda le-cylindrical eline-hex socket drive, ngakolunye uhlangothi, liletha ukuhanjiswa kwe-torque ephakeme kakhulu, amandla okufakwa okuhlangene, kanye nobuhle obuhlanzekile obukwenza kube ukukhetha okuthandwayo kwemihlangano yemishini lapho isikhala, ukwethembeka, nokubukeka konke kubalulekile. Ndawonye, ​​lezi zici ezimbili zenza i-Banga 8.8 i-black oxide socket cap cap isikulufa esisebenza ngezindlela eziningi, esingabizi kakhulu, futhi esinokwethenjelwa sohlelo olubanzi lwezinhlelo zokusebenza zezimboni.
