Iibholiti zezona mveliso zixhaphakileyo zehardware kubomi bethu bemihla ngemihla kwaye zidlala indima ebaluleke kakhulu kubomi bethu.Nangona kunjalo, abantu abaninzi abayiqondi inkcazo kunye nobukhulu beebholithi.Namhlanje, siya kukunika isingeniso sezenzululwazi ukubonakaliswa okuchanekileyo kweebholiti ze-anchor, ngethemba lokukunceda.
1. Ukukhethwa kwemathiriyeli yebholithi yesiseko
Ngokuqhelekileyo, izinto ze-anchor bolt kufuneka zibe yi-Q235.Ukuba amandla akonelanga, i-16Mn ibholiti yeankile inokukhethwa ngokubala.Ngokubanzi, ibholithi ye-ankile ye-Q235 iyasetyenziswa, kwaye ibholithi iyaqina kwaye iyayikhupha.
Enyanisweni, iibholiti ze-anchor aziyi kuphinda zidlale indima enkulu kwisakhiwo sentsimbi efakiweyo.Ingxenye kuphela ye-shear force ikhona, kuba umsebenzi oyintloko kukuxhasa emva kofakelo, ngoko ke inkcazo kufuneka ibhekiswe xa ukhetha iibholiti ze-anchor.Enyanisweni, sisebenzisa kuphela i-Q235B okanye i-Q235A, kwaye ngokubanzi asisebenzisi i-hook ye-Q345, enobude obungekho ngaphantsi kwe-150mm.
Iibholiti ze-Anchor: zinokwahlulwa zibe ziibholiti ze-ankile zezixhobo kunye neebholiti ze-anchor zesakhiwo.Ukukhethwa kweebholiti ze-anchor kufuneka kuthathelwe ingqalelo kwimbono yoxinzelelo, oko kukuthi, i-shear, i-tensile kunye ne-torsional forces eqhutywe yi-bolts support bolts.Ngexesha elifanayo, njengoko iibholiti ze-anchor, kufuneka zithwale ubukhulu becala amandla okucheba.Ngoko ke, i-Q235 (kwakhona iqwalasela ukushisa okusingqongileyo ukuphepha "i-blue brittleness") kufuneka ikhethwe kwiimeko ezininzi.Xa izakhiwo, izakhiwo okanye izixhobo ezilungiswe ziibholiti ze-ankile zendawo zinoxinzelelo olucacileyo okanye ukuxhatshazwa kwiibholiti ze-ankile, eyokuqala kufuneka ibalwe kwaye ikhethwe ngobubanzi okanye ikhethe ngokuthe ngqo i-16Mn ngamandla aphezulu, kwaye le yokugqibela kufuneka isonjululwe ngokwandisa i-anchor bolt. inani leebholiti zeankile.Ngapha koko, izixhobo ziyabiza ngoku.
Kungcono ukusebenzisa i-Q235A.I-Q235B ibiza kakhulu kune-Q235A.Iibholiti ze-ankile akufuneki zidityaniswe, ngoko kulungile ukusebenzisa iBanga A.
2. Ukucutshungulwa kwetekhnoloji yesiseko se-bolt material
Inkqubo yokucubungula i-anchor bolt: vula intambo kuqala, emva koko ugobe i-hook, kwaye uwele i-Q235 kunye nobude obufanayo be-150mm kufuphi ne-hook.Ukongezelela, kufuneka kuqatshelwe ukuba i-A3 yinombolo ye-brand endala, kwaye ngoku ihambelana nentsimbi ye-Q235A.A3, eligama elidlulileyo.Nangona isasetyenziswa, iphelela kulwimi oluthethwayo.Kungcono ukungayisebenzisi kumaxwebhu abhaliweyo.Yintsimbi yodidi A.Umenzi wolu hlobo lwentsimbi uqinisekisa kuphela ukusebenza komatshini kodwa kungekhona ukubunjwa kweekhemikhali xa eshiya i-factory, ngoko ke, izinto ezingcolileyo ezifana ne-S kunye ne-P zinokuba zincinci, kunye nomxholo wekhabhoni malunga ne-0.2%, ngokulinganayo Inombolo ye-20 yensimbi, elingana ne-Q235 kumgangatho omtsha.I-A3 kunye ne-A3F ngamagama angaphambili e-Q235-A, i-Q235-A.Intsimbi ye-F A3 kunye ne-Q235, i-Q345 ngamabakala e-carbon structural steel.I-A3 yibakala lensimbi kumgangatho omdala, kodwa umgangatho wangoku (GB221-79) awunalo ibakala elinjalo.
Kumgangatho wangoku, i-A3 ifakwe kwi-Q235.I-Q235 imele ukuba amandla emveliso yale ntsimbi yi-235MPa.Ngokufanayo, i-345 kwi-Q345 inokwahlulwa kwiindidi ezininzi, kubandakanywa: A - ukuqinisekisa iimpawu zomatshini, B - ukuqinisekisa iimpawu zomatshini kunye neempawu zokugoba ezibandayo, i-C - ukuqinisekisa ukubunjwa kweekhemikhali ... Kumgangatho omdala, intsingiselo ye-A , B, C ayahlukanga kakhulu kulowo kumgangatho omtsha (ndiqikelela ukuba oku kunjalo), kwaye 1, 2, 3...... Zisetyenziselwa ukubonisa amandla.U-1 umele amandla esivuno angama-195MPa, u-2 umele amandla esivuno angama-215MPa, kwaye u-3 umele amandla esivuno angama-235MPa.Ke i-A3 ilingana ne-Q235A kuhlobo olutsha.Emva kwayo yonke loo nto, i-A3 isetyenzisiwe ngaphambili, abantu abaninzi baqhele ukuyisebenzisa, njengokuba abanye beqhele ukusebenzisa iiyunithi ze "jin, liang".I-Q235 yintsimbi ye-carbon structural.Xa kuthelekiswa nomgangatho wakudala we-GB700-79 amabakala, i-A3 kunye ne-C3 Q345 yintsimbi ephantsi ye-alloy structural.Xa kuthelekiswa nomgangatho omdala we-1591-88 amabakala, kukho iipropati ezininzi kakhulu kunye nezicelo ze-12MnV, i-16Mn 16MnRE, i-18Nb kunye ne-14MnNb Q345 - i-shaft kunye ne-weldment ineempawu ezintle ezibanzi zomatshini, iipropati zokushisa eziphantsi, iplastiki enhle kunye ne-weldability.Zisetyenziswa njengezakhiwo zokuthwala imithwalo eguquguqukayo, iinxalenye zoomatshini, izakhiwo zokwakha, kunye nezakhiwo zetsimbi ngokubanzi zemikhumbi yoxinzelelo oluphakathi kunye noluphantsi, iitanki ze-oyile, izithuthi, iikhreyini, oomatshini bemigodi, izityalo zamandla, iibhulorho, njl. njl., kwaye zinokusetyenziswa kwiindawo ezishushu. ukuqengqeleka okanye iimeko eziqhelekileyo.Zingasetyenziselwa izakhiwo ezahlukeneyo kwiindawo ezibandayo ngaphantsi - 40 ℃.
