Ngeke kushiwo ukuthi intambo evamile futhi reamed imbobo intambo, kodwa umshudo ezejwayelekile futhi reamed imbobo bolt, ngoba ingxenye intambo kokubili kuyafana, umehluko wukuthi ingxenye induku ngaphandle intambo.Ngenxa yokuthi ingxenye yentambo iyafana, amandla e-axial ayafana.Kunegebe phakathi kwengxenye yenduku engenalutho yebhawodi evamile kanye nembobo, futhi amandla aguquguqukayo ayindawo kuphela yokungqubuzana endaweni yokuxhumana lapho ibhawodi liqiniswa (Yebo, uma ucabanga ukusika ngempela, amandla aguquguqukayo. empeleni amandla okugunda ebhawodi).Ukulingana kwebhowudi yembobo ephindwe kabusha enembobo ukubekezelelana, futhi amandla aguquguqukayo amandla okugunda webholidi yembobo evuselelwe.
Qapha
bm=1d i-double stud ngokuvamile isetshenziselwa ukuxhumana phakathi kwezingxenye ezimbili zensimbi ezixhunyiwe;I-GB/T897-1988 “I-Double-ended stud bm=1d” (i-bm ibhekisela ekugcineni kwembobo yesikulufu ebizwa ngokuthi i-screw end, ubude be-bm buhlobene nento yengxenye ezojijwa: bm=1d yensimbi kanye nethusi, lapho u-d ebhekisela kububanzi obungaphandle bentambo, ebhekisela kububanzi obukhulu.)
bm=1.25d kanye ne-bm=1.5d i-double stud ngokuvamile isetshenziselwa ukuxhuma phakathi kwesixhumi sensimbi esakhiwe nesixhumi sensimbi;GB898-1988 “Double stud bm= 1.25d”, GB899-1988 “Double stud bm=1.5d”.
bm =2d i-double stud ngokuvamile isetshenziselwa ukuxhumana phakathi kwesixhumi se-aluminium alloy nesixhumi sensimbi.Isixhumi sangaphambili sihlinzekwa ngembobo enentambo yangaphakathi, kanti lesi sakamuva sinembobo edlulayo.I-GB/T900-1988 “I-Double stud bm =2d”.
Imicu emikhawulweni yomibili yesitudi esinamaphethelo aphindwe kabili ubude obulinganayo kufanele ifaniswe namantongomane namawasha ezingxenyeni ezimbili ezixhunyiwe ezinezimbobo.GB/T901-1988 “Equal length double stud Class B”, GB/T953-1988 “Equal ubude besifundo esiphindwe kabili Ikilasi C”.Omunye umkhawulo we-welding stud uhlanganiswe ebusweni bengxenye exhunyiwe, kanti enye iphetho (i-threaded end) idlula engxenyeni exhunyiwe ngembobo yokudlula, bese i-washer ifakwe, futhi i-nut iboshwe, ngakho-ke. ukuthi izingxenye ezimbili ezixhunyiwe zixhunywe zizonke.I-GB/T902.1 “I-Welding stud ye-welding manual”, i-GB/T902.2 “I-Welding stud ye-arc stud welding”, i-GB/T902.3 “Isitudi sokushisela sokushisela isitoreji samandla”, i-GB/T902.4 “Isitudi sokushisela se-arc stud ukushisela i-ard stud isikhathi esifushane”.
Qaphela:
Intambo esetshenziswa kuntambo ephindwe kabili (GB/T897-900) imvamisa iyintambo evamile emaholoholo, kanti intambo evamile evamile noma intambo ehambisanayo yoguquko nayo ingasetshenziswa ngokwesidingo (ngokuya nge-GB1167/T-1996 “intambo efanelekile yenguquko. ”).Ibanga elilinganayo le-double head stud -B grade, lingasetshenziswa ngokuya ngesidingo30Cr, 40Cr, 30CrMnSi, 35CrMoA40MnA noma 40B ukukhiqizwa kwezinto ezibonakalayo, ukusebenza kwayo ngokuvumelana nesivumelwano phakathi kwamaqembu anikezelayo kanye nesidingo.Ukwakheka kwamakhemikhali we-Welding stud, ngokusho kwe-GB/T3098 .1-2010 izinhlinzeko, kodwa okuqukethwe kwayo kwekhabhoni ephezulu akufanele kube ngaphezu kuka-0.20%, futhi akumele kwenziwe ngensimbi yokusika yamahhala.
6. Ukuqina: Ikhono lempahla yokumelana nezinto eziqinile zendawo ezicindezelwe ebusweni bayo kuyinkomba yokusebenza ukulinganisa izinga lokuthambile nobulukhuni bezinto zensimbi.Ukuhlolwa kobulukhuni bezindlela (uBrinell, Rockwell, Vickers)Izimfuneko zokulungiselela isampula: Iziphetho ezimbili zesampula ziyahambisana, indawo engaphezulu iyisicaba, futhi akukho mafutha noma i-oxide evunyelwe.
Indawo yokuhlola 10~35°
Ekutholeni ubulukhuni bebhawodi, akukho ukwelashwa kokushisa kwamabhawodi, kudingeka kuphela ukwenza ubulukhuni bobuso, ngaphakathi kwe-ange efanelekayo kulayini.Uma kuyibhowodi yokwelapha ukushisa, kuyadingeka ukusika ubulukhuni ebusweni bobubanzi ekugcineni.Isikhundla sokuhlola siboniswa esithombeni.Ukuhlolwa kobulukhuni kuku-1/2R ebusweni, futhi ukuqina kuhlangabezana nezinga.
Ukuqina kwe-Bolt kunomgogodla kanye ne-core, ingaphezulu libhekisela ekusetshenzisweni kwe-Vickers noma ukuqina kwe-Rockwell ngemuva kokukhipha ukugqwala okungaphezulu, njll. Umnyombo kufanele ube ekukhishweni kwekhanda ingxenye engu-1/2 ububanzi ubude ebusweni naphakathi. 1/2 indawo yokudlala ubulukhuni, umehluko phakathi kobulukhuni obubili awukwazi ukudlula i-30HV, ubuso buphakeme kune-30HV okubonisa ukuthi i-carburizing engaphezulu, ayivunyelwe, Uma ingaphezulu lingaphansi kwe-30HV, kusho ukuthi ubuso bukhishwe , futhi akuvunyelwe.
I-nati elijwayelekile le-8-grade kufanele liphathwe ngokushisa, kepha awekho ukwelashwa ngokushisa, inati elijwayelekile lebanga lesi-8 ngokuvamile lenziwa ngensimbi engama-35, ukuhlolwa kokuqina nakho kucacisiwe, indawo ejwayelekile ayidingeki, umenzi wokwelapha ukushisa. ihlola ubulukhuni ngemva kokwelashwa kokushisa, i-metric nut ngokuvamile iphulwa kusukela phakathi ukuze kuhlolwe ubulukhuni benhliziyo yayo, inati eliyi-inch ngokuvamile liphulwa kobunye bobuso (okungukuthi, ukusika imibese emibili phezulu), ukuhlola ubulukhuni. maphakathi nengxenye yendawo eyodwa, futhi amantongomane amancane avame ukugugiswa esigabeni 0.2 ~ Hlola ubulukhuni ngemva kwamabholithi angu-0.3mm.4.6 ~ 6.8 awadingi ukwelashwa kokushisa;Ifakwe kubakaki yohlobo 2 lwamantongomane aphezulu.
Izinga likazwelonke le-GB3098.1 kanye nezinga likazwelonke le-GB3098.3 libeka ukuthi ukuqina kokulamula kukalwa ku-1/2 yerediyasi yengxenye enqamulayo yengxenye.Esimeni sanoma iyiphi ingxabano ngesikhathi sokwamukelwa, ubulukhuni be-Vickers buzosetshenziswa njengesivivinyo sokulamula.Okungenani ukufundwa oku-3 kufanele kuthathwe isampula ngayinye.
Indawo yokuhlola ukulamula: Lapho ubika imiphumela yokuhlolwa phakathi komthengi nomthengisi ngezinjongo zokulamula, ukuhlolwa kokuqina kuzokalwa endaweni emaphakathi (r/2) yerediyasi yendawo esikiweyo eyidayamitha eyodwa ukusuka ekugcineni kwendawo ibhawudi noma i-stud.Uma usayizi womkhiqizo uvuma, thatha ukufundwa oku-4 ekugcineni kwalesi bhawudi noma i-stud.Imikhiqizo yobubanzi obuncane ingabuye ihlolwe kusetshenziswa indawo ehambisanayo yetheminali yekhanda lomshudo elihambisana nendawo engaphezulu eyisikiwe.Ukuze kuhlolwe okuvamile, ubulukhuni bamabhawodi, izikulufu noma izikhonkwane zingahlolwa ekhanda, emsileni noma eshank ngemva kokususwa kwendawo efanele.
Kuzo zonke izigaba, uma inani lokuhlola lidlula umkhawulo ongaphezulu wobulukhuni, isifanekiso kufanele sisuswe endaweni yobubanzi begama ukusuka ekugcineni kwesifanekiso, kanye nendawo emaphakathi yesampula kanye nendlela yochungechunge endaweni ephakathi nendawo ukuhlolwa, inani lokuhlolwa kabusha akufanele lidlule umkhawulo ongaphezulu wobulukhuni, uma ngokungangabazeki, ubulukhuni be-Vickers (HV) kufanele kwamukelwe njengesinqumo.Ukuhlolwa kokuqina kobuso kungatholakala ekugcineni komkhiqizo noma unqenqema lweheksagoni, futhi indawo yokuhlola kufanele igaywe kancane noma ipholishwe ukuze kuqinisekiswe ukuphindaphinda kokuhlolwa kanye nesimo sangempela sendawo yesampula.I-HV0.3 isetshenziswa ekuhlolweni kokulamula kokuhlolwa kokuqina kobuso.Ubulukhuni bobuso obuhlolwe nge-HV0.3 buzoqhathaniswa nenani lokuhlola ubulukhuni bomnyombo nalo elihlolwe nge-HVo.3, futhi umehluko akufanele udlule amanani obulukhuni obungu-30 HV.Ukuqina kobuso obukhulu kunokuqina okuyisisekelo Amanani wokuqina we-30 HV akhombisa ukuthi isifanekiso sishisiwe.Emikhiqizweni enamabanga 8.8 kuya ku-12.9, umehluko phakathi kokuqina kobuso nokuqina kwengqikithi ungasetshenziswa ukunquma ukuthi umkhiqizo une-carburizing ngaphezulu.Ubulukhuni bomkhiqizo abuhlobene ngokuqondile namandla e-theoretical tensile.Ukunqunywa kwevelu yobulukhuni obukhulu akusekelwe ekucatshangweni komkhawulo wamandla aphezulu.
Qaphela: Kufanele kuqashelwe ukuthi ukuhluka kokwenyuka kwenani lokuqina kubangelwa ukushisa kwe-carburizing noma ukusebenza okubandayo.
