I-Hex Bolt yoLwakhiwo oluPhezulu
Iibholti zeNtloko zeHex eziqhelekileyo
Ezi bolts ikakhulu ziibolts ezirhabaxa ze-C-grade, apho inani elincinci liyi-A kunye ne-B-grade precision bolts. Zinamandla aphantsi kwaye zihlala zisetyenziswa njengezinto zokubopha okwethutyana okanye uqhagamshelo kwiindawo ezithwala umthwalo wesibini.
Iiparameters eziphambili:
Ziyahambelana nemigangatho efana ne-GB/T 5780-2000 (umsonto ongaphelelanga) kunye ne-GB/T 5781-2000 (umsonto opheleleyo). Iinkcukacha zomsonto zigubungela i-M5-M64. Amanqanaba okusebenza ikakhulu yi-3.6, 4.6, kunye ne-4.8. Umzekelo, i-bolt yebanga le-4.8 inamandla okutsalwa angama-400MPa kunye namandla okuphuma angama-320MPa. Izinto ezisetyenzisiweyo ikakhulu yintsimbi yokwakha yekhabhoni ye-Q235. Amanqanaba A kunye no-B ziibholts ezichanekileyo, ezibonelela ngokuchaneka okuphezulu kodwa zikwabiza iindleko eziphezulu. Iibholts zeBanga le-C ziibholts ezirhabaxa, ezinobunono obuphantsi bomatshini kodwa amaxabiso aphantsi; zezona zibholts ziqhelekileyo ezisetyenziswa kakhulu kwizakhiwo zentsimbi.
Izicelo:
Ifanelekile ukuqiniswa okwethutyana kwezakhiwo zentsimbi, njengokubeka kunye nokudibanisa izinto zentsimbi ngexesha lokwakha; ikwafanelekile nakwizakhiwo zesibini ezithwala umthwalo, ezifana nezixhasi zesakhiwo sentsimbi encinci, ukudityaniswa kwezinto ezingezizo ezithwala umthwalo, kunye noqhagamshelo kwizakhiwo zentsimbi ezinokuqhekeka kamva.
Iibholithi zentloko ezinkulu ezineenxantathu ezinamandla aphezulu
Ezi zizinto zokubopha ezibalulekileyo kwiindawo eziphambili zezakhiwo zentsimbi ezithwala umthwalo, ezisetyenziswa rhoqo kwiipaya zokudibanisa (eziqulethe i-bolt e-1, i-nut e-1, kunye nee-washer ezi-2). Ukusebenza kwazo kunye nokuchaneka kwazo kudlula kakhulu ezo ze-bolts eziqhelekileyo.
Iiparamitha eziphambili:
Ihambelana nomgangatho we-GB/T 1228-2006; amanqanaba okusebenza ikakhulu yi-8.8 kunye ne-10.9. Iibholiti zeBanga le-10.9 zinamandla okutsalwa angama-1040-1240 N/mm², amandla okutsalwa angadluli kwi-940 N/mm², kunye nobunzima beVickers obuphakathi kwama-312 kunye nama-367. Iibholiti zeBanga le-8.8 zinamandla okutsalwa angama-830-1030 N/mm² kunye namandla okutsalwa angama-660 N/mm². Uninzi lwazo zenziwe ngentsimbi yekhabhoni ephakathi okanye intsimbi ye-alloy kwaye zifuna unyango lobushushu ukuphucula iimpawu zazo. Ezinye iibholiti ezinamandla aphezulu nazo ziyanyangwa nge-galvanizing kunye nezinye iindlela zokulwa nokugqwala.
Imeko Ezisebenzayo:
Ifanelekile kwiindawo ezithwala umthwalo oyintloko zezakhiwo zentsimbi, ezifana nokudibanisa imiqadi yentsimbi kwiibhulorho, uqhagamshelo lwamaqhuqhuva kwizakhiwo zesakhelo sentsimbi esiphakamileyo, ukulungiswa kwesakhiwo esiphambili seenqaba zokuhambisa umbane, kunye nokuqiniswa kwezixhobo ezithwala umthwalo kwizakhiwo zentsimbi ezinkulu zefektri. Ezi meko zineemfuno eziphezulu kakhulu zozinzo kunye nokhuseleko loqhagamshelo. Iibholiti zentloko ezinkulu ezineehexagonal ezinamandla aphezulu zinokufezekisa ukuqina kwe-torque ngokuchanekileyo, zixhomekeke ekukhuhlaneni ukuhambisa imithwalo kwaye ziqinisekise amandla okuthwala umthwalo ngokubanzi wesakhiwo.
Iimpawu Eziqhelekileyo kunye Namanyathelo Okusebenzisa
Iingenelo eziqhelekileyo:
Uyilo lwentloko enamacangca asixhenxe lwenza kube lula ukufaka nokuqinisa izikrufu, nto leyo eyenza ukuba zifaneleke zombini ukufakwa ngoomatshini kunye nokufakelwa ngesandla. Uninzi lusetyenziswa neenati ezinamacangca asixhenxe kunye neewashers ezifanelekileyo ukuphucula ukutywinwa kunye nokuzinza koqhagamshelo. Ezinye zifumana unyango lwe-hot-dip galvanizing okanye olunye unyango lokulwa nokugqwala ukuze zandise ubomi bazo bokumelana nokugqwala ukuze zisetyenziswe ngaphandle.
Amanyathelo okusebenzisa:
Iibhalti ezahlukeneyo akufuneki zixutywe. Umzekelo, ibholti enamandla aphezulu yebanga le-10.9 ayinakusetyenziswa nenati eqhelekileyo yebanga le-4.8. I-torque yebhalti enamandla aphezulu kufuneka ilawulwe ngokungqongqo ngexesha lokufakwa; impazamo yesitshixo se-torque kufuneka ibe ngaphakathi kwe-±5% ukuze kuthintelwe ukuqina kakhulu, okunokubangela ukuqhekeka kwebholti, okanye ukuqina okungaphelelanga, okunokuchaphazela amandla oqhagamshelo. Ukugcinwa kufuneka kukhuselwe emvuleni nasemanzini ukuthintela ukubola komsonto kunye nomonakalo. Ukuba ibholti kunye nenati azihambelani, ukusetyenziswa kwazo akuvumelekanga ngokungqongqo.
