1. Ukuhlukaniswa kwama-fasteners
Kunezinhlobo eziningi zama-fasteners, ezingahlukaniswa ikakhulu ezigabeni ezilandelayo ngokuya ngesimo nokusebenza:
I-Bolt: isivinini se-cylindrical ngentambo, imvamisa esetshenziswa ngokubambisana ne-nati, ukufeza umphumela wokuqinisa ngokujikeleza nati. Ama-bolts asetshenziswa kabanzi kumishini ehlukahlukene yemishini kanye nezakhiwo, futhi ziyizakhi ezibalulekile zokuxhuma nokulungisa izingxenye.
I-NUT: Ingxenye yingxenye esetshenziswa ngokuhlangana ne-bolt, enezimbobo ezinemicu ngaphakathi ehambelana nentambo ye-bolt. Ngokujikeleza nati, kungenzeka ukuqinisa noma ukukhulula i-bolt.
Isikulufa: Isikulufa luhlobo lwe-fastener olunemicu yangaphandle, imvamisa iklwebheke ngqo emgodini ofakwe kwengxenye yengxenye exhunyiwe ngaphandle kwesidingo se-nati ukuze ilingane. Izikulufa zingasebenza zombili izinhloso zokuqinisa nokubeka endaweni yokuhlala ngesikhathi senqubo yokuxhumeka.
I-Stud: I-Stud stud iluhlobo lwe-fastener ngentambo kuzo zombili iziphetho, ngokuvamile zisetshenziselwa ukuxhuma izingxenye ezimbili ezinkulu. Umphumela wokuqinisa ama-bolts uzinzile futhi ulungele izimo lapho zingamelana khona namabutho aphezulu.
IGasket: I-gasket yingxenye esetshenziselwa ukukhulisa indawo yokuxhumana phakathi kokuxhuma, ukuvikela ukukhululeka, nokunciphisa ukugqokwa. Ama-gaskets ajwayele ukusetshenziswa ngokubambisana nama-fasteners afana nama-bolts namantongomane.
Isikulufu sokuthepha: Ukushaya kwe-Self Taping uhlobo lwesikali esinemicu ekhethekile engathinta ngqo izimbobo ezihlanganisiwe engxenyeni exhunyiwe futhi ifinyeleleke. Izikulufo zokuthepha zisetshenziselwa kabanzi ukuxhuma izinto zepuleti elincanyana.
I-Rivet: I-Rivet iyi-fastener exhumanisa izingxenye ezimbili noma ngaphezulu ndawonye ngokuvuselelwa. Izixhumi ezihlanganisiwe zinamandla aphezulu nokuqina.
Ukuthengisa: Ukuthengisa yi-fasteners esetshenziselwa ukuxhuma nokubeka izingxenye ezimbili. Ngokuvamile ukuthengisa kunamadayimitha amancane nobude obude, okwenza balungele izimo ezidinga ukuma okunembile.
Ukugcina indandatho: Indandatho yokugcina yingxenye esetshenziselwa ukuvikela ukuhamba kwe-axial komgodi noma izingxenye zalo. Indandatho yokugcina ivame ukufakwa ekupheleni kobuso be-shaft noma umgodi, ukhawulela ukunyakaza kwe-axial of the shaft noma izingxenye zalo ngokuqina kwayo noma ukuqina kwalo.
Izikulufa zokhuni: Izikulufa zokhuni zisetshenziselwa kakhulu ukuxhuma izinkuni. Intambo yezikulufo ezi-Wood ajulile, kulula ukuyisongela ngokhuni, futhi inomphumela omuhle wokuqinisa.
I-Welding Nail: I-Welding Nail ingamandla aphezulu, i-fastener esheshayo ye-welding efanelekile yokwakhiwa kwensimbi ehlukahlukene kanye nezinkambu zokukhiqiza zezimboni. Siqukethe induku engenalutho nekhanda elingenalutho (noma isakhiwo ngaphandle kwekhanda lesipikili), elixhunywe ngokuqondile engxenyeni ethile noma isakhi sobuchwepheshe be-welding ukuze baxhumanele kanye nasezinhlanganweni ezithile ngokuzayo.
Umhlangano: Ingxenye eyakhiwe ngokuhlanganisa izingxenye eziningi ndawonye. Lezi zingxenye zingaba izingxenye ezijwayelekile noma izingxenye ezenzelwe ngokukhethekile. Inhloso yoMkhakha ukwenza lula ukufaka, ukulungiswa, noma ukuthuthukisa ukusebenza kahle kokukhiqiza. Isibonelo, ukuhlanganisa ama-bolts, amantongomane, kanye nama-washer ndawonye ukwakha umhlangano wokuqinisa ngokushesha okufakwa ngokushesha.
2. Imigomo yokuthola amazinga nezinhlobonhlobo
Lapho sikhetha ama-fasteners, kudingeka silandele le migomo elandelayo ukuthola izindinganiso nezinhlobo zazo:
Yehlisa ukuhlukahluka futhi uthuthukise ukusebenza kahle: ngenkathi izidingo zokusebenzisa okuphathelene nomhlangano, ama-fasteners ajwayelekile kufanele akhethwe ngangokunokwenzeka ukuze anciphise ukuhlukahluka nokucaciswa futhi athuthukise ukusebenza kahle kokukhiqiza.
Ukubeka phambili ukusetshenziswa kwezinhlobo zomkhiqizo ezijwayelekile: Izinhlobo zomkhiqizo ezijwayelekile zinama-surtvence aphezulu kanye nokushintshana, okunganciphisa izindleko zokukhiqiza kanye nesondlo. Ngakho-ke, noma nini lapho kungenzeka, kufanele kunikezwe kuqala ukusebenzisa izingxenye ezijwayelekile zomkhiqizo.
Nquma ukuhlukahluka ngokuya ngezidingo zokusebenzisa: Lapho ukhetha ama-fasteners, ukucubungula okugcwele kufanele kunikezwe endaweni yawo yokusebenzisa, izimo zokucindezela, izinto zokwakha, nezinye izinto ukuqinisekisa ukuthi ama-fasteners akhethiwe angahlangabezana nezidingo zokusebenzisa.
3. Ileveli yokusebenza kwemishini
Izinga lokusebenza kwemishini le-fasteners liyinkomba ebalulekile yokulinganisa amandla abo nokuqina kwawo. Ngokusho kwe-GB / T 3098.1-2010, ama-bolts, ama-screws kanye namanye ama-fasteners angahlukaniswa ngamazinga okusebenza amaningi anjenge-4.6, 4.8 ,,8, 10.8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8 ,,8, 10,8, 10,6, 10,8, 10,6, 10,8, 10,6, 10,8, 10,6, 10,8, 10,6, 10,8, 10,6, 10,8, 10,6, 10,8, 10,8 Isibonelo, i-bolt eneleveli yokusebenza engu-8.8 imele amandla ashubile e-800 MPA kanye namandla okuvuselela angama-80%, okungukuqina okuyisisekelo kwe-640 MPA.
4. Izinga lokunemba
Izinga le-fasteners libonisa ukunemba kwalo kokukhiqiza nokunemba okufanele. Ngokwemithetho evamile, imikhiqizo ye-fastener ingahlukaniswa ngamazinga amathathu: a, B, no-C. Phakathi kwabo, izinga linokunemba okuphezulu kakhulu ne-C level linemba eliphansi kakhulu. Lapho ukhetha ama-fasteners, izinga labo lokunemba kufanele linqunywe ngokuya ngezidingo zokusebenzisa.
5. Intambo
Imicu iyingxenye ebalulekile ye-fasteners, futhi ukwakheka kwawo nosayizi banomthelela omkhulu ekuxhumekeni kwama-fasteners. Ngokusho kwemithetho evamile, izinga lokubekezelela lemicu lingahlukaniswa libe ngu-6h, 7h, njll. Intambo ecocekile inokusebenza okuhle kokukhulula i-anti futhi ilungele izimo ezidinga ukubekezelela ukudlidliza kube nemithelela enkulu.
6. Ukucaciswa
Ukucaciswa kwama-fasteners kuvame ukufaka amapharamitha amabili: ububanzi nobude. Lapho ukhetha ama-fasteners, kungakuhle ukuthi ukhethe ama-maameter kanye nobude ngaphakathi kwebanga elijwayelekile lokucaciswa ukuze unciphise ukusungula kanye nezindleko zokukhiqiza. Ngasikhathi sinye, ukuze kukhethwe ububanzi, uchungechunge lokuqala lwamanani kufanele lukhethwe ngangokunokwenzeka ukuze uthuthukise ubuntu nobuningi be-fasteners.
Ngamafuphi, ama-fasteners, njengezakhi ezibalulekile zokuxhuma nokulungisa izingxenye, zidlala indima ebalulekile ekukhiqizeni kwezimboni. Ngokuqonda ukuhlukaniswa, imigomo yokukhetha, kanye namapharamitha wezobuchwepheshe ahlobene nama-fasteners, singakhetha kangcono futhi asebenzise ama-fasteners. Lokho kuphetha ukwaba kwanamuhla. Ngibonga kakhulu ngokunaka kwakho nokufunda.
