Umenzi weFektri waseTshayina Umthengisi weDin 7991 Hexagon Socket Countersunk Head Cap Bolt

Ukusetyenziswa:

Kumphezulu womngxuma wokufakelwa kwinxalenye edibanisayo, kucutshungulwa isokhethi ejikelezileyo engama-90-degree, kwaye intloko yesikrufu somatshini esithe tyaba ikule sokhethi ijikelezileyo, egudileyo nomphezulu wenxalenye edibanisayo. Izikrufu zomatshini ezithe tyaba zikwasetyenziswa ngamanye amaxesha ngezikrufu zomatshini ezithe tyaba ezinentloko ejikelezileyo. Olu hlobo lwesikrufu luhle ngakumbi kwaye lusetyenziswa kwiindawo apho umphezulu unokuvumela ukuphuma kancinci.

Ikhowuni yentloko yesikrufu sentloko esifakwe i-countersunk ine-engile yekhowuni engama-90 °. Ngokwesiqhelo, i-engile ye-apex ye-drill bit esandul’ ukuthengwa yi-118 ° -120 °. Abanye abasebenzi abangaqeqeshwanga abazi lo mahluko we-engile, kwaye badla ngokusebenzisa i-120 ° drill Reaming, nto leyo ebangela ukuba izikrufu zentloko ezifakwe i-countersunk azixinwa xa kuqiniswa izikrufu zentloko ezifakwe i-countersunk, kodwa zinomgca osezantsi kwentloko yesikrufu, enye yezizathu zokuba izikrufu ezibizwa ngokuba yi-countersunk zingakwazi ukubamba ngokuqinileyo.

Amanyathelo okhuseleko ngexesha lokusetyenziswa:
1. Ubushushu bomngxuma ojikelezayo kufuneka bube yi-90 °. Ukuqinisekisa oko, kungcono ukuba bube ngaphantsi kwe-90 °, bungadluli kwi-90 °. Eli licebo eliphambili.
2.Ukuba ubukhulu beshiti yesinyithi bungaphantsi kobukhulu bentloko yesikrufu sentloko esifakwe kwi-countersunk, ungasitshintsha isikrufu esincinci, okanye endaweni yoko wandise umngxuma ube mncinci kunokwandisa umngxuma ukuze ububanzi bomngxuma ongezantsi bube bukhulu kwaye inxalenye ingaqini.
3. Ukuba kukho imingxunya emininzi yezikrufu efakwe kwi-countersunk kwicandelo, cacisa ngakumbi ngexesha lokwenziwa. Nje ukuba i-drill igobile, kunzima ukubona i-assembly, kodwa ingaqiniswa logama nje impazamo incinci, kuba xa isikrufu singaqinanga kakhulu. Inkulu (malunga ne-8mm), xa kukho impazamo kumgama womngxuma, intloko yesikrufu iya konakala ngenxa yamandla xa iqinisiwe, okanye iya kuqina.
