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

Ukusetyenziswa:

Phezulu komngxuma wokuxhoma kwisiqwenga sokudibanisa, i-socket ye-conical ejikelezayo engama-90 icutshungulwa, kwaye intloko ye-flat machine screw ikule sokethi ejikelezileyo, ehlanjululwayo kunye nomphezulu wesiqwenga sokudibanisa. Izikrufu zomatshini weflethi zikwasetyenziswa kwezinye izihlandlo ezinentloko engqukuva izikrufu zomatshini weflethi. Olu hlobo lwe-screw luhle kakhulu kwaye lusetyenziswa kwiindawo apho umphezulu unokuvumela ukukhupha okuncinci.

Ikhowuni yentloko yesikrufu sentloko ye countersunk ineengile yecone eyi 90 °. Ngokuqhelekileyo, i-engile ephezulu ye-drill bit esanda kuthengwa yi-118 ° -120 °. Abanye abasebenzi abangaqeqeshwanga abawazi lo mahluko engile, kwaye kaninzi sebenzisa 120 ° drill Reaming, nto leyo ebangela ukuba izikrufu entloko countersunk azihluzwanga xa kuqiniswa izikrufu entloko countersunk, kodwa umgca emazantsi entloko jijwa, nto leyo enye yezizathu zokuba into ebizwa ngokuba izikrufu countersunk ayikwazi ukubamba ngokuqinileyo.

Izilumkiso ngexesha lokusetyenziswa:
1.I-taper yomngxuma wokubuyisela kufuneka ibe ngama-90 °. Ukuyiqinisekisa, kungcono ukuba ngaphantsi kwe-90 °, ingabi ngaphezu kwe-90 °. Eli liqhinga eliphambili.
2.Ukuba ubukhulu bephepha lentsimbi bungaphantsi kobunzima bentloko ye-screw yentloko ye-countersunk, unokutshintsha i-screw encinci, okanye kunoko wandise umngxuma omncinci kunokwandisa umngxuma ukuze ububanzi bomngxuma ophantsi ube mkhulu kwaye inxalenye ayiqinile.
3. Ukuba kukho imingxunya emininzi ye-screw countersunk kwinxalenye, yichaneke ngakumbi ngexesha lomatshini. Emva kokuba i-drill igoso, kunzima ukubona indibano, kodwa inokuqiniswa nje ukuba impazamo incinci, kuba xa i-screw ingaqinanga kakhulu Enkulu (malunga no-8mm), xa kukho impazamo kumgama womngxuma, intloko ye-screw iya kukhubazeka ngenxa yokunyanzeliswa xa igxininiswe, okanye iya kuqiniswa.
