Bolt nigice gisanzwe cyubukanishi, gikoreshwa ahantu henshi. Numutwe hamwe na screw, ibice bibiri bigize urwego rwicyuma gifatika, bigomba gukoreshwa bifatanije nimbuto, cyane cyane kugirango habeho guhuza ibice bibiri nu mwobo. Birashoboka ko udafite igitekerezo kijyanye nubwiza bwibikoresho bya bolt, iyi ngingo izakumenyekanisha kubintu bya bolt, ubumenyi bufite ireme, kugirango abantu benshi bashobore kwiga kumenya utuntu duto duto twa bolt.
Imiterere n'ibikoresho bya bolts bivuga iki?
Ubwiza bwa bolt buhuye na 4.8, 8.8, 10.9 nindi mico ya bolt.
Ibikoresho bikoreshwa mu gukora bolt ni Q235, 35K, 40Cr, 45 # ibyuma, 35CrMo ibyuma, 304 ibyuma bitagira umwanda na 316 ibyuma bitagira umwanda, nibindi.
Ibyuma byoroheje bishobora kubyara ingufu nkeya gusa, ibyuma bya karubone yo hagati birashobora kubyara ingufu ziciriritse, ibyuma bya karubone ndende hamwe nicyuma gishobora kuvamo imbaraga zikomeye. Ibyiciro bimwe bya bolt byerekana imiterere yimiti hamwe nubukanishi bujyanye, ariko kandi bikerekana ibikoresho.
Dore urutonde rwibisanzwe bya bolt, bitewe nibikoresho byakoreshejwe. Icyiciro cya 4.8 gishobora kuba Q235, Q195 nibindi bikoresho byoroheje. Icyiciro 5.8, Q235, kirashobora gukoreshwa mubikoresho byose kandi ntibisaba kuvura ubushyuhe. Urwego 8.8, umurambararo wa diameter 16 mm cyangwa munsi yayo, 35 #, ubushyuhe buvuwe, mm 16 cyangwa zirenga, 45 # hamwe nicyuma gito cya karuboni, ibyuma bivura. Urwego 10.9, icyuma giciriritse giciriritse, kuvura ubushyuhe. Kuvura ubushyuhe 35Crmo 40Cr, nibindi
Ese imbaraga-zohejuru zishobora gutandukana na bolts zisanzwe nibikoresho byabo?
Bolt muri rusange igabanijwe ukurikije urwego rwimbaraga zabo.
Urwego rwimikorere ya Bolt 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 nibindi, amanota arenga 10, harimo na bolts 8.8 no hejuru yayo ikozwe mubyuma bya karuboni nkeya cyangwa ibyuma biciriritse biciriritse hamwe nubushyuhe (bikomye, byoroheje), bizwi cyane nka bolts zisanzwe. Urwego rwa Bolt rwerekana urwego rugizwe nibice bibiri bigize imibare, ukurikije imbaraga zumwanya wizina wibikoresho bya bolt hamwe nagaciro kagereranijwe.
Kurugero, urwego rwimikorere rwicyiciro 8.8 bolts nuburyo bukurikira
1, nominal tensile imbaraga yibikoresho bya bolt ni 800MPa;
2, umusaruro wimbaraga yibikoresho bya bolt ni 0.8;
3, umusaruro wizina wimbaraga yibikoresho bya bolt ni 800 × 0.8 = 640MPa. Byakunze gukoreshwa cyane-imbaraga zikomeye ni urwego 8.8 na 10.9, naho ibisanzwe bikoreshwa cyane ni urwego 4.8.
Nigute ushobora kuvuga itandukaniro riri hagati yimbaraga-nini na bolts zisanzwe?
Ibikoresho bya karuboni bigabanijwemo imbaraga nyinshi nibikoresho bisanzwe. Ibyuma bya karubone byakozwe mubikoresho bikomeye byitwa imbaraga zikomeye. Kurugero, dukoresha 45 # ibyuma kugirango tubyare imitwe ibiri, kandi kurugero, dukoresha ibyuma 35k kugirango tubyare ibyuma bitandatu hamwe na hexagonal, ibi byuma biraterwa, hazabaho uburyo bwo kuvura ubushyuhe, nyuma yo kurangiza, urwego rwa bolt rugera mucyiciro cya 8.8, nubwo ibikoresho byongerewe imbaraga, niyo mpamvu bitwa imbaraga zikomeye. Kurugero, dukoresha ibyuma 40Crmo alloy ibyuma kugirango tubyare 10.9 hex, kandi kurugero, dukoresha ibyuma bya 35Crmo alloy ibyuma kugirango tubyare ibihingwa 12.9, nibindi, izi nzego zirenze urwego 8.8, kubwibyo bita imbaraga zikomeye.
Bolt ikorwa nibikoresho bisanzwe bya karubone byitwa bolts bisanzwe. Kurugero, dukoresha ibikoresho bya Q235 kugirango tubyare ibice 4.8 bya mpandeshatu, nkibikoresho byacu bya A3 kugirango tubyare imbuto 4 za hexagonal, nibindi, nibindi, ibyo bikoresho nyuma yo kurangiza umusaruro bisaba gusa gusukura hejuru cyangwa kuvura amashanyarazi hejuru, kandi ntibisaba kuvura ubushyuhe, bityo byitwa bolts zisanzwe.
Duhereye kubyavuzwe haruguru, turashobora gushyiraho itegeko: ibyo bita imbaraga zikomeye, ni ukuvuga abafite imiterere yubukanishi bingana cyangwa burenze 8.8 kandi bisaba kuvura ubushyuhe, byitwa imbaraga zikomeye. Bolt ifite imashini iri munsi ya 8.8 yitwa bolts isanzwe, ifite imbaraga za 4.8, zidasaba kuvura ubushyuhe.
