Ukususela Uhlaselo Nails

Self-tapping Izikrufu
I-self-tapping screw luhlobo lwe-fastener ene-threaded, eqhubela intambo yabasetyhini kumngxuma owenziwe ngaphambili wesinyithi okanye izinto ezingezizo.

Intshayelelo yeMveliso
Ngenxa yokuba iyazibumba okanye inokucofa intambo ehambelana nayo, inamandla aphezulu okuchasa ukukhulula kwaye inokudityaniswa kwaye iqhawuke.Izixhobo zokuzibamba izikhonkwane zingahlulwa zibe yi-carbon steel kunye nensimbi engenasici, phakathi kwayo i-carbon steel ikakhulu i-1022 medium carbon steel, edla ngokusetyenziswa kwiingcango, iifestile kunye namaphepha ensimbi.Intloko yayo ngumphezulu othweleyo owenziwe yinxalenye enesiphelo esinye senziwe sayimilo eyandisiweyo.
Ukwenza intambo kunye nokusika intambo, intloko ye-Flat Countersunk, intloko ye-Oval Countersunk, intloko yePan, iHex kunye neHex washer Head zezona zibalulekileyo, ezithatha phantse i-90% yazo zonke izikrufu zokuzibhora.Ezinye iindidi ezintlanu yi-Flat Undercut, i-Flat Trim, i-Oval Undercut, i-Oval Trim, kunye ne-Fillister, ezingaqhelekanga kakhulu.

Uphuhliso
Ngelo xesha, yayisetyenziselwa ukudityaniswa kwamaphepha entsimbi kwimibhobho yeenkqubo zokupholisa umoya, ngoko yayikwabizwa ngokuba zizikrufu zentsimbi.Emva kweminyaka engaphezu kwama-80 yophuhliso, inokwahlulwa ibe ngamaxesha amane-ukwenza imisonto, ukusika intambo, ukuqengqeleka kwentambo kunye nokuzibhora.
I-thread-forming self-tapping screw iphuhliswe ngokuthe ngqo kwi-screw ye-tin, kunye ne-screws zokwenza intambo, umngxuma kufuneka ugrunjwe kwangaphambili, emva koko i-screw ifakwe emngxunyeni.
Umsonto wokusika i-self-tapping screw usika inotshi enye okanye ngaphezulu ekupheleni komsila womsonto, ukuze xa isikrufu sikrwelelwe kumngxunya owenziwe ngaphambili, umsila kunye nezinyo lesikrufu zingasetyenziselwa ukusika imazi ehambelanayo. umsonto ngendlela efana nokucofa.Ingasetyenziswa kwiipleyiti ezishinyeneyo, izinto eziqinileyo okanye eziethe-ethe ekungekho lula ukuzibumba.
Izikrufu zokuzicofa ezinemisonto ziyilwe ngokukodwa imisonto kunye neziphelo zomsila, ukuze izikrufu ziqengqeleke zibe yimisonto yabasetyhini ngokwazo phantsi koxinzelelo oluphakathi.Kwangaxeshanye, izinto ezijikeleze umngxuma zinokuzalisa ngokulula indawo yomsonto kunye nezinyo ezantsi kwi-self-tapping screws.Ngenxa yokuba amandla ayo okukhuhlana amancinane kunezikrufu ezizincamathelisayo, anokusetyenziswa kwizinto ezityebileyo, itorque efunekayo ukujikeleza ilawulwa ngcono, kwaye amandla emva kokudityaniswa aphezulu.Umgangatho wobunjineli inkcazo yentambo eqengqelekayo yokuzicofa isikrufu iphezulu kwaye icace ngakumbi kunaleyo yokwenza okanye ukusika i-self-tapping screw kunyango lobushushu obuphathekayo, eyenza i-thread rolling self-tapping screw a real "structural" fastener.
I-screw self-drilling ayifuni u-pre-drilling, enokugcina iindleko kwaye idibanise ukugaya, ukucofa kunye ne-screwing.Ubunzima bomphezulu kunye nokuqina okungundoqo kwesikrufu somsila we-drill ziphezulu kancinane kunezo zesikrufu sokuzicofa ngokubanzi, kuba isikrufu somsila we-drill sinomsebenzi owongezelelweyo wokomba, kwaye isikrufu somsila we-drill sisafuna uvavanyo lokungena ukuvavanya ukuba Screw unokubhoboza kwaye ucofe intambo ngexesha elichaziweyo.

Ukuhlelwa
Intloko ejikelezayo: Lolona hlobo lwentloko oluxhaphakileyo lusetyenziswa kwixesha elidlulileyo.
Intloko ecaba: uyilo olutsha olungathatha indawo yentloko engqukuva kunye nentloko yekhowa.Intloko inobubanzi obukhulu, kwaye i-periphery yentloko idibaniswa nomda ophezulu, okwenza ukuba idlale indima yokuqhubela phambili kwi-torque ephezulu.
Intloko yeHexagon: Olu luhlobo olusemgangathweni apho itorque ifakwa kwintloko ene-hexagonal.Ibonakaliswe ngokunquma iikona ezibukhali ukuvala uluhlu lokunyamezela.Ifanelekile kwiipateni ezahlukeneyo ezisemgangathweni kunye needayamitha ezahlukeneyo zentambo.
Iintlobo zokuqhuba: slotted, Philips, kunye pozi .
Imigangatho: iMigangatho yeSizwe (GB), iMigangatho yesiJamani (DIN), iMigangatho yaseMelika (ANSI) kunye neBritish Standard (BS)

Bume bento
Okwangoku, kukho iindidi ezimbini ze-self-tapping screws eziqhelekileyo ezisetyenziswa e-China: intloko ye-countersunk kunye ne-pan yentloko.Unyango lwabo lokugqiba luhlala luyi-blue zinc plating, kwaye luyacinywa ngexesha lokuvelisa, into esiyibiza ngokuba yi-heat treatment, ukwenzela ukuqinisa ubunzima.Iindleko emva kokunyanga ubushushu ziphezulu ngokwemvelo kunoko ngaphandle konyango lobushushu, kodwa ubunzima bayo abukho phezulu njengoko emva kokunyanga ubushushu, ngoko kuxhomekeke kwiimveliso ezisetyenziswa ngabasebenzisi.

Isicelo
I-self-tapping screws yokutshixa nayo isetyenziselwa ukudibanisa phakathi kweepleyiti zetsimbi ezibhityileyo.Intambo yayo intambo eqhelekileyo kunye necandelo lomnqamlezo we-arc triangular, kwaye umphezulu wentambo nawo unobunzima obuphezulu.Ngoko ke, xa udibanisa, i-screw ingaphinda icofe intambo yangaphakathi kumngxuma ongezantsi wentambo yesiqwenga esidibeneyo, ngaloo ndlela senza uxhumano.Olu hlobo lwe-screw lubonakaliswa yi-torque ephantsi ye-screwing kunye nokusebenza kokutshixa okuphezulu.Inokusebenza okungcono kunezikrufu eziqhelekileyo zokuzicofa kwaye inokusetyenziswa endaweni yezikrufu zoomatshini.
I-self-tapping screws ye-wallboard isetyenziselwa ukudibanisa phakathi kwe-gypsum wallboard kunye ne-metal keel.Intambo yayo yintambo ephindwe kabini, kwaye umphezulu wentambo unobunzima obuphezulu (≥HRC53), enokuthi ifakwe ngokukhawuleza kwi-keel ngaphandle kokwenza imingxuma eyenziwe ngaphambili, ngaloo ndlela yenza uxhumano.
Umahluko phakathi kwe-self-drilling screws kunye ne-self-tapping screws kukuba i-elf-tapping screws kufuneka ihambe kwiinkqubo ezimbini: ukubhola kunye nokucofa.Kwizikrini zokuzibhobhoza, iinkqubo ezimbini zokugaya kunye nokucofa zidibene.Isebenzisa i-drill bit ephambi kwesikrufu ukugrumba kuqala, kwaye emva koko isebenzisa isikrufu ukucofa, ukonga ixesha kunye nokuphucula ukusebenza kakuhle.
Intloko ye-pan kunye ne-hexagon head self-tapping screws zifanelekile kwiimeko apho intloko ivunyelwe ukuba ibonakale.Ihexagon intloko izikrufu zokuzicofa zinokusebenzisa itorque enkulu kunezikrufu ezizibethayo zentloko.I-Countersunk self-tapping screws ifanelekile kwiimeko apho intloko ingavumelekanga ukuba ibonakale.

Ingcaciso
Ngokuqhelekileyo, kuthetha ukuba intambo i-self-tapping, ukwenzela ukuba ayifuni ukusetyenziswa ngamantongomane.Zininzi iindidi zezikrufu, kubandakanywa intloko yehexagon yangaphandle, intloko yepani, intloko ye-countersunk kunye nentloko yehexagon yangaphakathi.Kwaye umsila ukhonjwe ngokubanzi.

Umsebenzi
I-self-tapping screws isetyenziselwa isinyithi esingenasinyithi okanye esithambileyo, ngaphandle kwemingxuma yangaphambili kunye nokucofa;I-self-tapping screws ibonakaliswe, ukwenzela ukuba "i-self-tap".I-self-tapping screws inokwemba imicu ehambelanayo kwizinto eziza kulungiswa yimicu yazo, ukuze zihambelane ngokusondeleyo.
