Iibholiti zentsimbi zekhabhoni ezinamandla aphezulu zizibophelelo ezenziwe ngobunjineli ezichanekileyo eziyilelwe ukumelana nemithwalo enzima kakhulu kunye nemikhosi yokucheba kwizicelo ezibalulekileyo zesakhiwo. Yenziwe ukusuka kumabanga aphakathi ukuya kwikhabhoni ephezulu yentsimbi (efana ne-1045, 10B21, okanye 10B33) kwaye iphantsi kweenkqubo zonyango lobushushu obungqongqo njengokucinywa kunye nobushushu, ezi bholiti zifezekisa ubulukhuni obuphezulu kunye namandla esivuno xa kuthelekiswa nezinye iindlela ezisezantsi zekhabhoni. Njengomvelisi okhethekileyo osekelwe e-Handan, i-Hebei-intliziyo ye-China ye-fastener industry-sivelisa la macandelo ukuhlangabezana nemigangatho engqongqo yamazwe ngamazwe kuquka i-GB, i-DIN, i-JIS, kunye ne-ANSI. Ubuchwephesha bethu beminyaka elishumi buqinisekisa ukuba ibholithi nganye ibonelela ngomsebenzi othembekileyo wokwakha, oomatshini abanzima, kunye neeprojekthi zeziseko ezingundoqo kumazwe angaphezu kwama-26.
Zeziphi iiBolts zentsimbi zeCarbon eziPhezulu?
Amandla aphezulu e-carbon steel bolts amele udidi oluthile lwe-fasteners apho ukubunjwa kwezinto eziphathekayo kunye nenkqubo yokuvelisa ilungiselelwe umthamo omkhulu wokuthwala umthwalo. Ngokungafaniyo neBanga lesi-2 okanye iBanga lesi-5 leebholiti ezenziwe ngentsimbi ephantsi-khabhoni, ukwahluka kwamandla aphezulu kusebenzisa umxholo wekhabhoni ngokuqhelekileyo ukusuka kwi-0.30 ukuya kwi-0.60%. Eli nqanaba lekhabhoni lonyuka, lidityaniswe nezinto ezixubeneyo ezifana ne-boron okanye i-manganese, ivumela intsimbi ukuba iphendule ngokufanelekileyo kunyango lobushushu.
Uphawu oluchazayo lwezi bholithi yiprofayili yepropathi yomatshini. Babonisa amandla aphezulu okuqina (olona xinzelelo luphezulu abanokumelana nalo ngelixa besolulwa) kwaye bavelise amandla (indawo apho baqala khona ukonakala ngokusisigxina). Kwiimeko zoshishino, ezi zihlala zihlelwa phantsi kwamabanga afana ne-ASTM A325, ASTM A490, ISO 8.8, ISO 10.9, okanye ISO 12.9. Igama elithi "amandla aphezulu" ayikokuthengisa nje; lubuchwephesha obuchaza ukufaneleka kwebholithi kumalungu abalulekileyo okhuseleko apho ukungaphumeleli kunokubangela umonakalo omkhulu kwisakhiwo.
Ukuqulunqwa kwezinto ezingundoqo kunye neePropati
Ukusebenza kwamandla aphezulu e-carbon steel bolts kudibene ngokuthe ngqo kwisakhiwo sabo se-metallurgical. Izinto ezisisiseko ngokuqhelekileyo ziquka insimbi ye-carbon steel okanye i-medium carbon alloy steel. Amanqaku aqhelekileyo aquka:
- 1045 Intsimbi yeCarbon: Intsimbi yekhabhoni esebenza ngeendlela ezininzi enika ibhalansi elungileyo yamandla kunye ne-ductility, ehlala isetyenziselwa i-ISO 8.8 kunye ne-10.9 yeklasi yeebholiti.
- 10B21 / 10B33 Intsimbi yeBoron: Ukongezwa kwe-boron kwandisa kakhulu ukuqina, kuvumela ukungena okunzulu kunye nokufana okufanayo kwonyango lobushushu, olubalulekileyo kwiibholithi ezinkulu zedayamitha.
- 35K / 45K Intsimbi: Isetyenziswa rhoqo kwimigangatho ye-GB yaseTshayina, la mabanga abonelela ngomqolo oyimfuneko wekhabhoni ukuze kuphunyezwe ukuthambeka okuphezulu emva kokucima kunye nokuqunjelwa.
Ngokuphathwa kobushushu obulawulwayo, i-microstructure yentsimbi iguqulwa ibe yi-martensite epholileyo. Esi sakhiwo sibonelela ngeyona ndlela ilungileyo indibaniselwano yobulukhuni kunye nokuqina, iqinisekisa ukuba ibholithi inokumelana neempembelelo zequbuliso ngaphandle kokuba brittle.
Inkqubo yokuvelisa: Ukusuka kwintsimbi ekrwada ukuya kwiFastener egqityiweyo
Ukuvelisa iibholiti zetsimbi zekhabhoni ezikumgangatho ophezulu zifuna ukuhamba komsebenzi ophucukileyo. Kwiziko lethu elise-Handan, sidibanisa iindlela ezibandayo ezibandayo kunye neendlela ezishushu zokubumba kunye nokulungiswa kwe-thermal. Ukuqonda le nkqubo kunceda abathengi baxabise isindululo sexabiso leziqhoboshi ezenziwe ngobuchwephesha ngokuchasene nezinye iindlela zamayeza afana nalawo aveliswe ngabenzi.
1. Isihloko esibandayo kunye ne-Hot Forging
Ukubunjwa kokuqala kwe-bolt blank kuxhomekeke kubukhulu bayo kunye nebakala. Kwi-diameters encinci, i-heading ebandayo ikhethwa njengoko isebenza-iqinisa izinto eziphathekayo, ukwandisa amandla ngokulungelelanisa ukuhamba kweenkozo. Kwiidayamitha ezinkulu okanye amabakala aphezulu (njenge-ISO 12.9), i-forging eshushu iyaqashwa. Le nkqubo ibandakanya ukufudumeza intsimbi kwisimo seplastiki kwaye iyenze phantsi koxinzelelo oluphezulu, oluphelisa i-voids yangaphakathi kwaye idale isakhiwo esiqinileyo sengqolowa esikwaziyo ukuphatha uxinzelelo olunzulu.
2. Ukuqengqeleka kwemisonto
Ngokungafaniyo nemisonto yokusika, esusa izinto kwaye idale amanqaku oxinzelelo, ukuqengqeleka kwentambo kwenza imisonto ngokususa intsimbi. Le nkqubo yokusebenza ebandayo ixinzelela ukwakheka kweenkozo kwiingcambu zentambo, ikhuthaza kakhulu ukuxhathisa ukukhathala. Ukusetyenziswa kwamandla aphezulu, iintambo eziqengqelekayo zibalulekile ukukhusela ukusilela kwangaphambi kwexesha phantsi kokulayisha i-cyclic.
3. Unyango lobushushu: Ukucinywa kunye nokuthoba
Eli lelona nyathelo libaluleke kakhulu kwiibholithi zentsimbi zekhabhoni ezinamandla kakhulu. Iibholiti zifudunyezwa kwiqondo lokushisa elithile le-austenitizing kwaye emva koko zipholile ngokukhawuleza (zicinywe) kwioli okanye emanzini. Oku kudala ulwakhiwo lwemartensitic olunzima kakhulu kodwa olunokonakala. Emva koko, iibholiti ziphinda zifudunyezwe kwiqondo lokushisa eliphantsi (umsindo) ukukhulula uxinzelelo lwangaphakathi kunye nokubuyisela ukuqina. Le nkqubo iphindwe kabini iqinisekisa ukuba ibholithi ihlangabezana nobunzima obufunekayo kunye neenkcukacha zokuqina kokuqina ngaphandle kokuthanda ukukrazula phantsi kwemithwalo yokothuka.
4. Unyango loMphezulu kunye noKwaleka
Intsimbi yekhabhoni iyakwazi ukubola. Ukukhusela ingqibelelo yebholithi kunye nokwandisa ubomi bayo benkonzo, unyango oluhlukeneyo lwamanzi lusetyenziswa. Iinketho eziqhelekileyo ziquka i-zinc plating, i-hot-dip galvanizing, kunye ne-black oxide coating. Kwimibhobho ephezulu, i-hydrogen embrittlement iyingozi enkulu ngexesha le-electroplating. Ke ngoko, iprotocol yethu yokuvelisa ibandakanya iinkqubo ezingqongqo zokubhaka emva kokutyalwa ukusasaza iiathom zehydrogen, ukuqinisekisa ukuba iipropathi zoomatshini zihlala zinjalo.

Imibuzo Ebuzwa Rhoqo (FAQ)
Uthini umahluko phakathi kweebholithi zeBakala 8.8 kunye neBakala 10.9?
Umahluko ophambili ulele ekuzinzeni kwabo kunye namandla esivuno. Iibholithi zeBanga le-10.9 zinobuncinane bokuqina obusezantsi bokuqina (1000 MPa) kunye namandla esivuno (900 MPa) xa kuthelekiswa neebholithi zeBanga lesi-8.8 (800 MPa tensile, 640 MPa isivuno). IBakala 10.9 lisetyenziselwa izicelo ezibaluleke ngakumbi, ezinomthwalo ophezulu.
Ngaba iibholiti zentsimbi zekhabhoni ezinamandla aphezulu zinokudityaniswa?
Ngokuqhelekileyo, akukho. Ukuwelda iibholiti zamandla aphezulu kutshintsha i-microstructure ephethwe bubushushu, inciphisa kakhulu amandla azo kwaye ibenze babe brittle. Ukuba i-welding iyafuneka, iinkqubo ezithile ze-welding ephantsi kwe-hydrogen kunye nonyango lokushisa emva kwe-weld ziyimfuneko, kodwa ngokuqhelekileyo kuyacetyiswa ukuba kusetyenziswe iibholiti ezenzelwe ukuwelda okanye ezinye iindlela zokujoyina.
Ndiyithintela njani i-hydrogen embrittlement kwiibholithi ezicwecwe?
I-hydrogen embrittlement kwenzeka xa iiathom ze-hydrogen zisasazeka kwintsimbi ngexesha lokufakwa kwe-electroplating. Ukuthintela oku, abavelisi kufuneka babhake iibholiti kwiqondo lobushushu elithile (elidla ngokuba malunga ne-200°C) kwisithuba esibekiweyo ngoko nangoko emva kokucwenga ukukhupha i-hydrogen. Inkqubo yethu yokuvelisa ilandela ngokungqongqo le migaqo yokuqinisekisa ukhuseleko.
Buthini ubomi beshelufu yeebholithi zentsimbi zekhabhoni ezinamandla aphezulu?
Ukuba zigcinwe kwindawo eyomileyo, yangaphakathi ekude ne-ejenti ezonakalisayo, iibholiti ze-carbon steel zamandla aphezulu zinobomi obungenasiphelo. Nangona kunjalo, xa sele ifakwe okanye ibonakaliswe kwiindawo ezinzima, ubomi babo buxhomekeke ekusebenzeni kokukhusela kwabo kunye nobukhulu beemeko.
Ngaba uyabonelela ngeenkonzo zokwenziwa kwesiqhelo?
Ewe. Ukusebenzisa oomatshini bethu abaphambili kunye neqela lobuchwephesha lobuchwephesha, silungiselela ukucaciswa okukhethekileyo, iimpawu, kunye nobungakanani ngokweemfuno zabathengi.
