Ngokuqhelekileyo, emva kokufakwa kwe-screws ye-countersunk self-tapping screws, ukubonakala kwamacandelo kucaba kwaye akuyi kuba ne-bulge.Amacandelo ayo agxininiswe ngokuqinileyo ahlulwe abe ngamancinci kwaye anzima.Ukutyeba kubhekiselele kumlinganiselo ozalanayo phakathi kobukhulu bamalungu kunye nobukhulu bezikrufu ezizibambayo ezizibambayo.Eyangaphambili kufuneka ibenkulu kuneyamva.Xa uqiniswa, kuya kubakho imisonto ngaphandle, kodwa into enye ekufuneka uyiqaphele kukuba i-countersunk screws kufuneka iqiniswe.
Isikrufu esinqandisiweyo esijikelezileyo
Ukongeza, ubukhulu becala bungaphantsi kobunzima bentloko ye-countersunk self-tapping screw, enye imeko.Kwizixhobo ezininzi zoomatshini, kuya kubakho iinxalenye zentsimbi, njengokudityaniswa phakathi kwesixhobo kunye nesigqubuthelo sentsimbi, kunye nokudityaniswa komnyango phakathi kweebhokisi.Ngenxa yokuba ubukhulu bendawo yokubopha buncinci, i-screw ngokusebenzisa umngxuma yenza umngxuma we-conical.Xa uqinisa i-countersunk self-tapping screw, intloko ye-screw ayicinezeli inxalenye yentsimbi yeshidi, kodwa umzantsi we-screw kunye nomphezulu we-threaded emngxunyeni ucinezela ukufa.Ngenxa yoku, ngamanye amaxesha sivakalelwa kukuba izikhonkwane ziqinile, kodwa i-sheet sheet ayiqinile ngokwenene.
Isikrufu somsonto wehexagon wangaphandle wokuzicofa
Ngethuba lofakelo lwe-screws ye-countersunk head tapping screws, i-taper yokubuyisela i-reaming kufuneka ibe ngaphantsi okanye ilingane ne-90 degrees kwaye ingabi ngaphezu kwama-90 degrees.Ukuba kukho imingxuma emininzi eyenziwe yi-countersunk screws kumacandelo, kuyimfuneko ukugcina ukuchaneka kwaye ugweme ukuphambuka ngexesha lokucubungula ukuqinisekisa ubuhle emva kokuhlanganisana.Ukuba kukho impazamo encinci, inokulungiswa kwaye iqiniswe kancinci.Kodwa ububanzi be-screw akufanele budlule i-8mm, ekufuneka igcinwe engqondweni.Ukuba ubukhulu be-countersunk self-tapping screw bukhulu kunobunzima be-sheet metal, kuyimfuneko ukutshintsha i-screw encinci okanye ukwandise umngxuma.Ukuze ugweme ukukhulula iinxalenye, kucetyiswa ukuba ungandisi i-diameter yokubuyisela.
Ngamafutshane, qaphela xa ufaka i-countersunk head tapping screws.Okokuqala, inokuqinisekisa ukufakwa okugudileyo, kwaye okwesibini, kunokwenza umphumo wofakelo ube yinto efanelekileyo.Oku ngasentla sisishwankathelo seendlela zokusetyenziswa kunye nezilumkiso ze-countersunk head tapping screws.Ndikholelwa ukuba ukufunda eli nqaku kuya kukunceda.
