I-China Factory Manufacturer Wholesale Supplier DIN 7991 Hexagon Socket Countersunk Head Cap Bolt

Ukusetshenziswa:

Ngaphezulu kwembobo efakwe engxenyeni yokuxhuma, isokhethi eyindilinga eyindilinga engu-90-degree iyacutshungulwa, futhi ikhanda lesikulufu somshini oyisicaba likulesi sokhethi esiyindilinga, esigubhayo ngobuso besiqeshana sokuxhuma. Izikulufu zomshini oyisicaba zibuye zisetshenziswe kwezinye izikhathi ngezikulufa zomshini wekhanda eliyindilinga. Lolu hlobo lwesikulufu luhle kakhulu futhi lusetshenziswa ezindaweni lapho indawo engaphezulu ingavumela ukuphuma kancane.

Ikhoni yekhanda lesikulufu sekhanda elishisiwe ine-engeli yekhoni engu-90 °. Ngokuvamile, i-engeli ephezulu ye-drill bit esanda kuthengwa ingu-118 ° -120 °. Ezinye izisebenzi ezingaqeqeshiwe aziwazi lo mehluko we-engeli, futhi ngokuvamile zisebenzisa i-120 ° drill Reaming, okuholela ekutheni izikulufu zekhanda ezishisiwe azicindezelwe lapho kuqiniswa izikulufu zekhanda ezishisiwe, kodwa umugqa ongezansi kwekhanda lesikulufu, okungesinye sezizathu ezenza lokho okubizwa ngokuthi izikulufu ze-countersunk zingakwazi ukubamba ziqine.

Izinyathelo zokuqapha ngesikhathi sokusetshenziswa:
1.I-taper yembobo yokubuyisela kabusha kufanele ibe ngu-90 °. Ukuze uqinisekise, kungcono ukuba ngaphansi kuka-90 °, hhayi ngaphezu kuka-90 °. Leli iqhinga eliyisihluthulelo.
2.Uma ubukhulu beshidi lensimbi bungaphansi kobukhulu bekhanda le-screw head screw, ungashintsha isikulufu esincane, noma kunalokho wandise imbobo encane kunokwandisa imbobo ukuze ububanzi bomgodi ongezansi bube bukhulu futhi ingxenye ingaqinile.
3. Uma kunezimbobo eziningi zesikulufa esiphikisayo engxenyeni, cacisa kakhulu ngesikhathi somshini. Uma i-drill isigwegwile, kunzima ukubona umhlangano, kodwa ingaqiniswa inqobo nje uma iphutha lincane, ngoba lapho isikulufu singaqinile kakhulu Esikhulu (cishe singabi ngaphezu kuka-8mm), uma kunephutha ebangeni lembobo, ikhanda le-screw lizokhubazeka ngenxa yokuphoqelela lapho liqiniswa, noma lizoqiniswa.
