Bolt na Nut kwa Kufuatilia Sehemu ya Viatu Kufuatilia Roller Kukata Edge
Ukubwa wa kawaida wa bolt ya kuchimba na nati zinaweza kutofautiana kulingana na muundo na mfano wa mchimbaji.Ukubwa wa kawaida ni pamoja na M12, M16, M20, na M24.
Hatua ya 1: Ukaguzi na uhifadhi wa malighafi
Malighafi ya bolt itaamuliwa kwa mbuni kulingana na utumizi.Nyenzo zitatumika kukaguliwa na kisha mahali pazuri pa kuhifadhiwa patambuliwe ili kuepusha kutokea kwa kutu na kufunika vizuri kunahitajika kutolewa.
Hatua ya 2: Utengenezaji wa bolt ambao haujasomwa / ambao haujakamilika
Mara nyingi urushaji na ughushi hutumika katika hatua hii.Njia zingine pia zinaweza kutumika:
1. Kuimba
2. Kuchapa (Haraka)
Hatua ya 3: Utengenezaji wa CNC
Baada ya sehemu hiyo kutengenezwa kupitia njia ya kughushi/kutupwa, kisha inatengenezwa kwa vipimo vinavyohitajika kwa kawaida na CNC.
Operesheni zinazofuatwa hapa ni: kuashiria, kutazama, kunyoosha.
Hatua ya 4: Matibabu ya joto
Matibabu ya joto hufanyika baada ya machining kufanya fasteners nguvu.Shughuli za ugumu na ukali hufuatwa.
Kwanza, ugumu unafanywa ili bolt inapokanzwa kwa joto la 850-900 ° C na kisha kuzimishwa kwenye vyombo vya habari vya baridi.
Pili, bolt huwashwa tena moto ili kurudisha boliti iliyo ngumu zaidi kuwa laini kidogo, ili boliti ibaki kuwa na nguvu.Kupokanzwa tena kunafanywa ili kuleta chini brittleness ya bolt ambayo ilitokea wakati wa ugumu.
Hatua ya 5: Kumaliza uso
Ifuatayo ni mchakato wa kumaliza uso.Kawaida, mchakato wa kusaga unafanywa ili kufanya uso kuwa laini kulingana na vipimo vya kumaliza uso.
Hatua ya 6: Kusokota kwa nyuzi
Baada ya kumaliza mchakato, rolling thread inafanywa na kufa mbili.Moja ni ya kusimama na nyingine ni kufa inayosonga ambayo kwa kweli inatoa shinikizo kwenye bolts na kuunda nyuzi.
Hatua ya 7: Mipako
Baada ya kusongesha uzi, boliti na viunzi vya skrubu hupakwa ili kuzuia kutu na kutu.Mfano mzuri wa upakaji wa bolt ni upakaji wa kijiometri katika boli ambazo zitajaribiwa kwa SST (Mtihani wa Kunyunyizia Chumvi) kulingana na idadi ya saa kama ilivyobainishwa.
Mashine inayoitwa FISCHERSCOPE hutumiwa kubainisha unene wa kupaka pamoja na vyombo vingine vya kupimia unene kama vile mita ya unene wa kupaka.
Hatua ya 8: Ukaguzi wa Fomu, Fit & Kazi:
Baada ya taratibu zote kufanyika, hatimaye sehemu huenda kukaguliwa.Inapaswa kukutana
1.Mtihani wa torque, SST
2.Kufaa na nut
3. Nguvu ya athari (mtihani wa athari charpy)
4.Jaribio la nguvu ya mkazo (%refusho ya bolt)
5.Ugumu wa msingi wa bolt
6.Unene wa mipako
Ukaguzi wa dimensional nk.
