Iibholiti zeHexagon ngokwenene zibhekisa kwiziqhoboshi ezibandakanya intloko ngesikrufu. Iibholiti zahlulwe kakhulu zibe ziibholiti zentsimbi kunye neebholiti zensimbi ezingenasici ngokwezinto eziphathekayo. I-ayini yohlulwe ngokwamabanga, ngamabakala aqhelekileyo ibe ngu-4.8, 8.8, no-12.9. Intsimbi engenastainless yenziwe ngentsimbi engatyiwayo SUS201, SUS304, kunye neebholiti ze-SUS316.
Iseti epheleleyo yeebholiti zehexagon inentloko yebhawudi, inati, kunye negasket ecaba.
Iibholiti zentloko ezine-hexagonal zizibhowuli zentloko ezine-hexagonal (inxalenye yemisonto) - c iibholiti zentloko ezine-hexagonal (iintambo ezigcweleyo) - i-c grade, ekwabizwa ngokuba zii-hexagonal head bolts (rough) hexagonal head bolts, izikrufu zentsimbi ezimnyama. Imigangatho esetyenziswa ngokuqhelekileyo ikakhulu: sh3404, hg20613, hg20634, njl.
Ibhawuthi yentloko yehexagon (efinyeziweyo njengebhawunti yehexagon) inentloko kunye nentonga ephothiweyo (
Amanqanaba okusebenza abanzi eebholithi ezisetyenziselwa ukudityaniswa kwezakhiwo zetsimbi ahlulwe abe ngamabakala angaphezu kwe-10, kubandakanywa i-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, kunye ne-12.9. Phakathi kwazo, iibholiti zebanga le-8.8 nangaphezulu, ezenziwe ngentsimbi ephantsi-carbon alloy okanye i-medium carbon steel kwaye ziphantsi konyango olufanelekileyo lobushushu (ukucima kunye nokushisa), ngokuqhelekileyo zibizwa ngokuba ziibholiti eziphezulu, ngelixa ezinye zibizwa ngokuqhelekileyo. njengeebholiti eziqhelekileyo. Amanqaku omgangatho wokusebenza kwebholithi aneenxalenye ezimbini zamanani ezimele ixabiso lamandla e-tensile nomlinganiselo wesivuno semathiriyeli yebholiti. Lo ulandelayo ngumzekelo.
Intsingiselo yeebholiti ezinomgangatho wokusebenza we-4.6 yile:
Amandla okuzibamba okubizwa ngokuba yi-bolt material afikelela kwi-400 mpa;
2. Umlinganiselo wamandla esivuno sezinto zebholithi ngu-0.6;
3. Amandla esivuno esiqhelekileyo semathiriyeli yebholi ukuya kuthi ga kwi-400 × 0.6=240MPa inqanaba
Iibholiti zamandla aphezulu kunye nenqanaba lokusebenza le-10.9, kunye nemathiriyeli emva konyango lobushushu lufikelela:
1. Amandla okuzinza okubizwa ngokuba yi-bolt material afikelela kwi-1000MPa;
2. Umlinganiselo wamandla esivuno sezinto zebholithi ngu-0.9;
Amandla emveliso yebhoti afikelela kwi-1000 × 0.9=900MPa kwinqanaba
Intsingiselo yamabakala ahlukeneyo okwenziwa kwebholiti ngumgangatho owamkelweyo kumazwe ngamazwe. Iibholiti ezinomgangatho ofanayo wokuvavanya ukusebenza kwemveliso zinomsebenzi ofanayo kungakhathaliseki ukuba ziziphi izinto kunye nemvelaphi yazo, kwaye kuphela ibakala lesalathisi sokusebenza kokhuseleko lingakhethwa ukuyila.
