Isakhiwo sensimbi ekhanyayo yinkqubo yentsimbi encinci kunye nebalulekileyo. Isetyenziswe ngokubanzi kwimizi-mveliso jikelele, ezolimo, zorhwebo, kunye nezakhiwo zenkonzo. Ikwasetyenziswa ekongezeni imigangatho, ekuguquleni nasekuqiniseni izakhiwo ezidala, nakwiindawo ezingenazo izinto zokwakha nakwiindawo ezinezothutho ezingafanelekanga. Ishedyuli yokwakha engqongqo kunye nezakhiwo ezishukumayo nezisusekayo zithandwa kakhulu ngabanini. Isixhobo esiyimfuneko kuthi xa sisakha ezi zikrweqe zentsimbi zikhaphukhaphu yi-drill-tailed self-tapping screws. Ke unolwazi olungakanani malunga nokuzicofa ngezikrufu?

"Izikhonkwane zokuzibhobhoza" zikwabizwa ngokuba "izikhonkwane zokugaya", "izikhonkwane zokugaya", "izikhonkwane zokuzibhobhoza", ezikwabizwa ngokuba yi "dovetail screws", IsiNgesi: SELF DRILLING SCREWS. Imigangatho yokuphunyezwa kwayo ibandakanya umgangatho wesizwe we-GB / T 15856.1-2002, umgangatho waseJamani we-DIN7504N-1995, kunye nomgangatho waseJapan JIS B 1124-2003.

Olu hlobo lwesikrufu lunencam yomsila we-drill, ethiywe ngegama lencam efana ne-twist drill. Ngexesha lokudibanisa, isikrufu sinokukhupha umngxuma osembindini ngokwaso, kwaye emva koko sisebenzise indawo enemisonto ekufutshane ukuze uzibethele kwaye ukhuphe isikrufu esihambelanayo kumngxunya kumphathi. Umsonto, ngoko ubizwa ngokuba yi-self-drilling kunye nezikrufu zokucofa.

Ngokwemigangatho yokuphunyezwa, izikrufu zomsila we-drill zingahlulwa zibe: umgangatho wesizwe we-GB / T, umgangatho waseJamani we-DIN, umgangatho waseJapan we-JIS, kunye nomgangatho wamazwe ngamazwe we-ISO.

Isenokwahlulwa ngokwezi ndidi zilandelayo ngokokusetyenziswa kunye nokumila:

1. Umnqamlezo we-pan e-recessed head self-drilling kunye nezikrufu zokucofa. I-Cross recessed pan head drilling screws nge-tapping screw thread Umgangatho wokuphunyezwa: GB/T 15856.1-2002 inezi nkcukacha zilandelayo: (ekwabizwa ngokuba ngumsila wentloko engqukuva).

2. I-Cross recessed countersunk head self-drilling kunye nezikrufu zokucofa. Cross recessed countersunk head drilling screws with tapping screw thread Umgangatho wokuphunyezwa: GB/T 15856.2-2002 inezi nkcukacha zilandelayo: (ekwaziwa ngokuba yi-flat drill tail, isaladi yentloko ye-drill tail).

3. Hexagon flange intloko izikrufu zokomba nge tapping Screw thread. Ukuphunyezwa komgangatho: GB/T 15856.4-2002. Inezi nkcukacha zilandelayo: (ekwabizwa ngokuba yihexagonal Dahua drill tail, enye yezikrufu zomsila we-drill. Eyona isetyenziswayo kunye neyona miba inkulu.)

4. Ihexagon washer entloko izikrufu zokomba ngomsonto wokucofa. Ukuphunyezwa komgangatho: GB/T 15856.5-2002. Inezi nkcukacha zilandelayo: (ekwabizwa ngokuba yi-hexagonal encinci yewasha drill tail.)
