Umkhiqizi Wefektri waseShayina Umhlinzeki Othengisa Izinto Eziningi I-DIN 7991 Hexagon Socket Countersunk Head Cap Bolt

Ukusetshenziswa:

Ebusweni bembobo yokufaka engxenyeni exhumanisayo, kucutshungulwa isokhethi eliyindilinga elingu-90-degree, kanti ikhanda lesikulufu somshini esiyisicaba likulesi sokhethi esiyindilinga, esihambisana nobuso bengxenye exhumanisayo. Izikulufu zomshini eziyisicaba nazo zisetshenziswa kwezinye izikhathi ngezikulufu zomshini eziyisicaba eziyindilinga. Lolu hlobo lwesikulufu luhle kakhulu futhi lusetshenziswa ezindaweni lapho ubuso bungavumela ukuphuma okuncane.

Ikhoni yekhanda lesikulufu sekhanda esingaphansi kwe-countersunk ine-engeli yekhoni engu-90 °. Ngokuvamile, i-engeli ephezulu ye-drill bit esanda kuthengwa ingu-118 ° -120 °. Abanye abasebenzi abangaqeqeshwanga abazi lo mehluko we-engeli, futhi bavame ukusebenzisa i-drill engu-120 ° Reaming, okuholela ekutheni izikulufu zekhanda ezingaphansi kwe-countersunk azicindezelwa lapho kuqinisa izikulufu zekhanda ezingaphansi kwe-countersunk, kodwa umugqa ophansi kwekhanda lesikulufu, okungenye yezizathu ezenza ukuthi izikulufu ezibizwa ngokuthi i-countersunk zingakwazi ukubamba ziqine.

Izinyathelo zokuphepha ngesikhathi sokusetshenziswa:
1. Ukushisa kwembobo yokushintshashintsha kufanele kube ngu-90 °. Ukuqinisekisa lokhu, kungcono kube ngaphansi kuka-90 °, kungabi ngaphezu kuka-90 °. Leli yicebo elibalulekile.
2.Uma ubukhulu bensimbi yeshidi bungaphansi kobukhulu bekhanda lesikulufu sekhanda esifakwe ekhoneni, ungashintsha isikulufu esincane, noma kunalokho wandise imbobo ibe ncane kunokwandisa imbobo ukuze ububanzi bembobo engezansi bube bukhulu futhi ingxenye ingaqini.
3. Uma kunezimbobo eziningi zezikulufo ezifakwe eceleni, cacisa kakhulu ngesikhathi somshini. Uma i-drill isigobile, kunzima ukubona ukuhlanganiswa, kodwa ingaqiniswa uma nje iphutha lincane, ngoba uma isikulufo singaqinile kakhulu. Esikhulu (cishe singadluli ku-8mm), uma kunephutha ebangeni lembobo, ikhanda lesikulufo lizophazamiseka ngenxa yamandla uma liqiniswa, noma lizoqiniswa.
