Ibholidi yokwandisa iyisixhumi esikhethekile esinentambo esisetshenziselwa ukulungisa ukusekela kwepayipi / ukuphakamisa / ubakaki noma izinto zokusebenza odongeni, phansi noma ikholomu.Amamaki e-carbon steel bolts ahlukaniswe abe ngu-3.6,4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 namanye amamaki angaphezu kwe-10. Izinombolo ngaphambi nangemva kwephuzu ledesimali ngokulandelana kwazo zibonisa amandla okuzisholo kanye nesilinganiso sesivuno. we-bolt material, isibonelo: ukumaka ama-bolts angu-8.8 kubonisa ukuthi amandla aqinile wezinto ezibonakalayo afinyelela ku-800MPa, futhi amandla okukhiqiza angu-0.8, okungukuthi, amandla ayo okukhiqiza afinyelela ku-800 × 0.8 = 640MPa.
Izinto zokwakha:
Amabanga amabhawodi okunweba ahlukaniswe abe ngu-45, 50, 60, 70 kanye no-80. Izinto ezibonakalayo zihlukaniswe ikakhulukazi zibe i-austenite A1, A2, A4;Martensite kanye ne-ferrite C1, C2, C4;Ukumelwa kwayo, isb A2-70;”- ” ngaphambi nangemuva kubonisa impahla yebhawodi kanye nebanga lamandla ngokulandelanayo.(1) Impahla yebholidi esetshenziswa kakhulu: Q215, Q235, 25 kanye nensimbi engu-45, ngezinjongo ezibalulekile noma ezibalulekile izingxenye zokuxhuma ezinentambo, ingakhetha 15Cr, 20Cr, 40Cr, 15MnVB, 30CrMrSi kanye nezinye izici eziphakeme zomshini zensimbi ye-alloy.(2) Ingcindezi evumelekile Ingcindezi evumelekile yoxhumo olucushiwe ihlobene nemvelo yomthwalo (umthwalo omile, oguquguqukayo), noma ngabe uxhumano luyaqiniswa, noma ngabe ukulayisha kuqala kudinga ukulawulwa, kanye impahla kanye nosayizi wesakhiwo soxhumano oluluchungechunge.
uhlobo:
Ibanga lamabhawodi ensimbi engagqwali lihlukaniswe ngama-45, 50, 60, 70, 80, impahla ihlukaniswe ikakhulukazi i-austenite A1, A2, A4, martensite ne-ferrite C1, C2, C4, indlela yayo yokukhuluma njenge-A2-70, "eyodwa" ngaphambi nangemuva ngokulandelana khombisa impahla yebhawodi kanye nebanga lamandla.
bakha:Ibhawodi yokunweba iqukethe ibhawodi elishona phansi, ishubhu yokunweba, iwasha eyisicaba, iwasha yasentwasahlobo, kanye ne-hex nut.
Lapho isetshenziswa, kuyadingeka ukubhoboza imbobo yobukhulu obuhambisanayo emzimbeni ongaguquki nge-drill yomthelela (isando), bese ufaka ibhawodi neshubhu lokunweba emgodini, bese uqinisa nati ukwenza ibhawodi, ishubhu yokwandisa. , ingxenye yokufaka kanye nomzimba ongaguquki inweba ngokuqinile ibe yinto eyodwa.Ngemva kokuqina kuzokhula, umsila webhawodi unekhanda elikhulu, ibhawodi ngaphandle libeka libe likhudlwana kunobubanzi bepayipi eliyindilinga, ingxenye yomsila inezimbobo eziningana, lapho Ibhawodi liqinisiwe, umsila wekhanda elikhulu uzoyiswa ekuvuleni kwepayipi ngaphakathi, ipayipi elikhulu, ukuze kufezwe injongo yokwandisa, bese ibhowudi igxilwe phansi noma odongeni, ukuze kuzuzwe inhloso yokuqothula. .
Amabhawodi wokunweba wesigaba sokusebenza esingu-4.6, okusho ukuthi:1, amandla okuzijwayeza wento yebhawodi yokunwetshwa afinyelela izinga elingu-400MPa;2.Isilinganiso se-flexion sempahla yebhawodi yokunwetshwa ngu-0.6;3, amandla okuvunwa okuziswana ento yebhawodi yokunwetshwa ngu-400×0.6=240MPaIncazelo yezinga lokusebenza lebhawodi yokunweba izinga lamazwe ngamazwe, izinga lokusebenza elifanayo lebhawodi yokwandisa. , kungakhathaliseki umehluko wezinto ezibonakalayo nemvelaphi, ukusebenza kwayo kuyafana, umklamo ungakhetha kuphela izinga lokusebenza.
Izinto ezidinga ukunakwa:
1, ukujula kokubhoboza: ukujula kokwakhiwa okuthile kungcono kunobude beshubhu yokwandisa cishe u-5 mm.Uma nje bukhulu noma bulingana nobude beshubhu yokwandisa, ubude be-bolt yokwandisa yangaphakathi esele emhlabathini bulingana noma bungaphansi kobude be-tube yokwandisa.2, izidingo ze-bolt yangaphakathi yokwandisa. phansi, yiqiniso, kunzima nakakhulu, kubuye kuncike kumandla wento oyidingayo ukuyilungisa.Amandla wamandla afakwe kukhonkolo (C13-15) izikhathi ezinhlanu ukuthi emzimbeni wezitini.3.Ngemva kokufaka kahle ibholidi yokukhulisa yangaphakathi engu-M6/8/10/12 kukhonkolo, amandla ayo aphezulu amile angu-120/170/320/510 kg ngokulandelana.Indlela yokufaka ye-bolt yokwandisa yangaphakathi ayinzima kakhulu, ukusebenza okuqondile kungokulandelayo;Okokuqala khetha i-alloy drill bit enobubanzi obufana nendandatho yokunweba (ishubhu) yesikulufu sokunweba, uyifake ku-drill kagesi bese ubhoboza odongeni, ukujula kwembobo kungcono kakhulu kufane nobude bebhawodi. , bese ubeka ikhithi yesikulufu sokunweba phansi emgodini, khumbula;Ungasikulufi isikulufu, ukuvimbela ukubhoboza imbobo kujulile uma ibhawodi liwela emgodini futhi akukuhle ukulikhipha.Bese ugoqa isikulufu ibhande elingu-2-3 ngemva kokuzwa ukuthi ibhowudi yokunweba yangaphakathi iqinile kodwa ayidedeleki bese uvala isikulufu isikulufu.
