I-Countersunk self-drilling screws

Umgaqo osebenzayo we-countersunk self tapping screws ulula kakhulu. Xa ifakwe kumphezulu wezinto eziphathekayo, i-spiral groove eyakhelwe kuyo iya kunqumla ngokuthe ngqo loo nto ibe yimingxuma efanelekileyo. Njengoko i-screw ijikeleza, isakhiwo se-toothed sentloko yayo siya kugubungela izinto eziphathekayo, ukuvumela ukuba i-screw ihlale endaweni.

Olu hlobo lwe-screw lunomsila obolileyo okanye ocacileyo ekupheleni, ngaphandle kwesidingo sokulungiswa kokuncedisa. Ngexesha lokudityaniswa, isikrufu sinokugrumba umngxuma osembindini ngokwaso, kwaye emva koko sisebenzise iindawo ezinemisonto ekufutshane ukuze uzicofe kwaye ukhuphe umsonto ohambelanayo kumngxunya kumphathi. Ke ngoko, kubizwa ngokuba sisikrufu sokuzibhoboza. Ikakhulu isetyenziselwa ukulungisa iileyile zetsimbi ezinemibala kwizakhiwo zetsimbi kwaye ingasetyenziselwa ukulungisa izinto zeshiti ezincinci kwizakhiwo ezilula, kodwa ayinakusetyenziselwa ukudibanisa kunye nokulungisa isinyithi kwisinyithi.

1. Ukubhola okuzenzekelayo ngokukhawuleza, ukubhola, ukucofa, kunye nokutshixa kugqitywe ngexesha elinye.

2. Ubuchule obuphezulu bokwakha, ukwandisa ukonga ixesha, ukuqinisekisa ukusebenza kakuhle, kunye nokuphucula inzuzo yezoqoqosho.

3. Amandla okubopha anamandla, amandla aphezulu okuqinisa kwangaphambili, kunye nokuzinza okuphezulu.

Umahluko phakathi kwe-countersunk self tapping screws kunye nezikrufu ezinentloko ezisicaba. I-Countersunk self tapping screws ibhekisa kwizikrufu zokuzicofa, ezithi, emva kokuziqinisa, zibe nentloko engekho phezulu kunomphezulu osicaba oqhutywa kuwo, kwaye zinokugcina umphezulu othe tyaba nomhle. Olu hlobo lwesikrufu luneegrooves ezahlukeneyo ezifana negroove ethe tye, i-cross groove, kunye ne-plum blossom groove, kwaye i-grooves kufuneka idlulele embindini we-screw ukuze ithintele ngempumelelo iitshiphusi ekuthinteleni i-groove. Umahluko phakathi kwe-countersunk self tapping screws kunye nezikrufu zentloko ecaba self tapping

① Imbonakalo eyahlukileyo

Umnqwazi we-countersunk self tapping screw unecala elinye elisicaba, ngelixa elinye icala linetaper; Umnqwazi onentloko ethe tyaba yokuzicofa isikrufu sicaba;

② Ukusebenzisa imiphezulu yoqhagamshelwano eyahlukeneyo

Umphezulu woqhagamshelwano phakathi kwe-countersunk self tapping screw kunye nesixhobo sokusebenza singumphezulu oyiconical, ngeli lixa isikhonkwane esinentloko ethe tyaba yokuzicofa ingumphezulu othe tyaba;

③ Amaqabane awohlukeneyo

Izikrufu ze-Countersunk self tapping zingasetyenziswa kuphela ngokudityaniswa newasher ezinomgangatho othile wetaper, ngelixa iqonga izikrufu zokuzicofa zingasetyenziswa kwidibaniso.
