DIN7991 Black Hex Socket Countersunk Head Cap Bolt
Yintoni i-hex socket countersunk head cap bolt?
Iibholiti ze-Countersunk ziziqhoboshi ezineentloko ezisicaba ezine-hex socket drive entloko.Iibholithi ze-Countersunk zinentamo yohlobo lwe-cone enentloko ethe tyaba, iibholiti ze-hex socket socket bolts, iibholiti zentloko ezisicaba zezinye iibholiti zentloko ye-hex.Imilinganiselo yeebholithi ze-Countersunk ichazwa kuzo zombini iimetric kunye nee-imperials ubungakanani kunye nepitch yesizwe edibeneyo (UNC), i-pitch ehlawulweyo (UNF), i-fixed pitch(UN) kunye neprofayili ye-ISO metric thread.Ezi ziveliswa kuzo zonke iindidi zezinto kunye neenkcukacha ze-ASTM kodwa zivame ukuveliswa phantsi kwe-F568 grade 8.8, 10.9,12.9, F593, BS, EN, ISO3506-1, SS304, SS316,2205, njl.
Usetyenziso
Phezulu komngxuma wokuxhoma kwisiqwenga sokudibanisa, i-socket ye-conical ejikelezayo engama-90 icutshungulwa, kwaye intloko ye-flat machine screw ikulo sokethi ejikelezileyo, ehlanjululwayo kunye nomphezulu wesiqwenga sokudibanisa.Izikrufu zomatshini weflethi zikwasetyenziswa kwezinye izihlandlo ezinentloko engqukuva izikrufu zomatshini osicaba.Olu hlobo lwe-screw luhle kakhulu kwaye lusetyenziswa kwiindawo apho umphezulu unokuvumela ukukhupha okuncinci.
Uninzi lwe-hex socket countersunk head cap bolts zisetyenziswa kwiindawo apho umphezulu wenxalenye awunakunyuswa emva kofakelo.Zimbini iindidi zamalungu ekufuneka zibotshelelwe.Ubukhulu bentloko, emva kokuba i-screw iqinisiwe, inxalenye yentambo ye-screw ayisayi kungena kumngxuma odibeneyo.Kule meko, i-countersunk head screw ngokuqinisekileyo inokuqiniswa.
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 zentloko countersunk azihluzwanga xa uqinisa izikrufu zentloko countersunk, kodwa umgca ezantsi kwentloko jijwa, nto leyo. esinye sezizathu zokuba into ebizwa ngokuba yi-hex socket countersunk head cap bolts ayikwazi ukubamba nkqi.
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 lesinyithi bungaphantsi kobunzima bentloko yesikrufu sentloko ye-countersunk, unokutshintsha isikrufu esincinci, okanye kunoko wandise umngxuma omncinci kunokwandisa umngxuma ukuze ububanzi bomngxuma osezantsi ube mkhulu. kwaye inxalenye ayiqinile.
3. Ukuba kukho imingxunya ye-hex socket countersunk head cap bolt kwinxalenye, ichaneke ngakumbi ngexesha lomatshini.Emva kokuba i-drill igoso, kunzima ukubona indibano, kodwa inokuqiniswa nje ukuba impazamo incinci, kuba xa i-screw ingaqini kakhulu Enkulu (malunga no-8mm), xa kukho impazamo kuyo. umgama womngxuma, intloko yesijivu iya konakala ngenxa yokunyanzeliswa xa iqinisiwe, okanye iya kuqiniswa.
