I-bolt yokwandisa ikhonkco ekhethekileyo yentambo esetyenziselwa ukulungisa inkxaso yombhobho / ukuphakamisa / isibiyeli okanye izixhobo eludongeni, umgangatho okanye ikholamu.Amabakala eebholiti zentsimbi zekhabhoni ahlulwe abe yi-3.6,4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 kunye namanye amabakala angaphezu kwe-10. Amanani ngaphambi nangemva kwedesimali ngokulandelelana abonisa amandla okuzinza kunye nomlinganiselo wesivuno. yempahla bolt, umzekelo: ukuphawula 8.8 iibholiti ibonisa ukuba amandla tensile izinto ukufikelela 800MPa, kwaye amandla isivuno 0.8, oko kukuthi, amandla ayo isivuno ukufikelela 800×0.8 = 640MPa.
Izixhobo:
Amabakala eebholithi zokwandiswa ahlulwe abe ngama-45, 50, 60, 70 kunye nama-80. Izinto eziphathekayo zahlulwe ikakhulu zibe yi-austenite A1, A2, A4; Martensite kunye ne-ferrite C1, C2, C4; ukumelwa kwayo, umz. A2-70;”- ” phambi nasemva kubonisa imathiriyeli yebholithi kunye nebakala lamandla ngokulandelelanayo. (1) Izinto zebholithi ezisetyenziswa ngokuqhelekileyo: Q215, Q235, 25 kunye ne-45 yentsimbi, ngenjongo ebalulekileyo okanye ekhethekileyo yokudibanisa iindawo ezidityanisiweyo, zingakhetha i-15Cr, 20Cr, 40Cr, 15MnVB, 30CrMrSi kunye nezinye iimpawu eziphezulu zomatshini wentsimbi ye-alloy. izinto eziphathekayo kunye nobukhulu besakhiwo soqhagamshelwano olunentambo.
uhlobo:
Ibakala iibholiti steel stainless yahlulwe ibe 45, 50, 60, 70, 80, izinto ngokuyintloko yahlulwe ibe austenite A1, A2, A4, martensite kunye ferrite C1, C2, C4, indlela yayo intetho ezifana A2-70, “enye” phambi nasemva ngokulandelelanayo bonisa imathiriyeli yebholiti kunye nebakala lamandla.
bamba:Ibholithi yokwandiswa iqulathe ibholithi ye countersunk, ityhubhu yokwandisa, iwasha esicaba, iwasha yasentwasahlobo, kunye nehex nut.
Xa kusetyenziswa, kuyimfuneko ukubhola umngxuma wobungakanani obuhambelanayo kumzimba osisigxina kunye ne-drill yempembelelo (ihamile), uze ubeke ibholithi kunye netyhubhu yokwandisa emngxunyeni, kwaye uqinise i-nut ukwenza ibholithi, ityhubhu yokwandisa. , icandelo lofakelo kunye nomzimba osisigxina ukwandisa ngokuqinileyo ukuya kwelinye.Emva kokuqina kuya kwanda, umsila webholithi unentloko enkulu, ibholithi yangaphandle ibeka isikhulu kancinane kunobubanzi bombhobho ojikelezayo, inxalenye yomsila inezivulo ezininzi, xa ibholithi iqinisiwe, umsila wentloko enkulu uya kusiwa ekuvulekeni kombhobho ngaphakathi, umbhobho omkhulu, ukufezekisa injongo yokwandisa, kwaye emva koko ibholithi igxininiswe emhlabeni okanye eludongeni, ukufezekisa injongo yokuhluma. .
Iibholithi zokwandiswa kweklasi ye-4.6, okuthetha ukuthi:1, amandla okuzinza okubizwa ngokuba yimathiriyeli yebholithi yokwandisa ifikelela kwinqanaba le-400MPa;2.Umlinganiselo we-flexion wesixhobo sokwandiswa kwebholithi ngu-0.6; 3, amandla okuvunwa okubizwa ngokuba yi-400×0.6=240MPaIntsingiselo yomgangatho wokusebenza webholithi yokwandiswa ngumgangatho wamazwe ngamazwe, umgangatho ofanayo wokusebenza webholithi yokwandisa. , kungakhathaliseki ukuba umehluko kwizinto eziphathekayo kunye nemvelaphi, ukusebenza kwayo kuyafana, uyilo lunokukhetha kuphela izinga lokusebenza.
Imiba efuna ukuqwalaselwa:
I-1, ubunzulu bokubetha: ubunzulu besakhiwo esithile bungcono kunobude betyhubhu yokwandisa malunga ne-5 mm.Ngethuba nje lilikhulu okanye lilingana nobude betyhubhu yokwandisa, ubude bebholidi yokwandisa yangaphakathi eseleyo emhlabeni bulingana okanye bungaphantsi kobude betyhubhu yokwandisa.2, iimfuno zebholiti yokwandisa yangaphakathi. emhlabeni, ngokuqinisekileyo, kunzima ngakumbi, kuxhomekeke kumandla ento ofuna ukuyilungisa.Amandla anamandla afakwe kwikhonkrithi (C13-15) ngamaxesha amahlanu kumzimba wezitena.3.Emva kokufaka ngokuchanekileyo i-M6/8/10/12 ibholithi yokwandiswa kwangaphakathi kwikhonkrithi, amandla ayo aphezulu azinzileyo yi-120/170/320/510 kg ngokulandelelanayo.Indlela yokufakela i-bolt yangaphakathi yokwandisa ayinzima kakhulu, umsebenzi othile ulandelayo;Okokuqala khetha i-alloy drill bit enobubanzi obufanayo njengeringi yokwandisa (ityhubhu) ye-screw yokwandisa, yifake kwi-drill yombane kwaye emva koko uqhube udonga, ubunzulu bomngxuma bungcono bufana nobude bebholithi. , kwaye emva koko ubeke ikiti yokwandisa i-screw ezantsi emngxunyeni, khumbula;Musa ukujija isikrufu, ukuthintela ukugrumba umngxuma kunzulu xa ibholiti yawela emngxunyeni kwaye ayilunganga ukuyikhupha.Emva koko jija isikrufu 2-3 ikhonkco emva kokuva ukuba ibholithi yokwandisa yangaphakathi iqinile kodwa ayikhululekanga kwaye emva koko usijike isikrufu.
