Isakhiwo sensimbi ekhanyayo siwuhlelo olusha futhi olubalulekile lwesakhiwo sensimbi. Isetshenziswe kabanzi kumabhilidi ajwayelekile ezimboni, ezolimo, ezentengiselwano kanye nezinkonzo. Ibuye isetshenziselwe ukwengeza phansi, ukuguqula, nokuqinisa izakhiwo ezindala, nasezindaweni ezingenazo izinto zokwakha nasezindaweni ezinezokuthutha ezingesihle. Uhlelo lokwakha oluqinile kanye nezakhiwo ezinyakazayo nezisusekayo zithandwa kakhulu ngabanikazi. Into ebalulekile kithi uma sakha lezi zakhiwo zensimbi elula izikulufu zokuzithepha ezi-drill-tailed. Ngakho-ke kungakanani okwaziyo ngezikulufa zokuzithepha?

"Izikulufu zokuzibhoboza" zibuye zibizwe ngokuthi "izikulufu zokubhoboza", "izikulufu zokubhoboza", "izikulufu zokuzibhoboza", ezibuye zibizwe ngokuthi "izikulufu ze-dovetail", isiNgisi: SELF DRILLING SCREWS. Izindinganiso zayo zokusetshenziswa zibandakanya i-GB/T 15856.1-2002 ejwayelekile kazwelonke, i-DIN7504N-1995 ejwayelekile yaseJalimane, kanye ne-Japanese standard JIS B 1124-2003.

Lolu hlobo lwesikulufu lunomsila wokubhoboza, oqanjwe ngethiphu elifana ne-twist drill. Phakathi nokuhlanganisa, isikulufu singazibhoboza ngokwaso imbobo emaphakathi, bese sisebenzise ingxenye exhumene eduze ukuze sizithephe futhi sikhiphe isikulufu esifanayo embobeni yesithwali. Intambo, ngakho-ke ibizwa ngokuthi izikulufa zokuzibhoboza nezokuthinta.

Ngokwamazinga okusebenza, izikulufu zomsila wokubhoboza zingahlukaniswa zibe: i-GB/T ejwayelekile kazwelonke, i-DIN evamile yaseJalimane, i-JIS evamile yaseJapane, kanye ne-ISO evamile yamazwe ngamazwe.

Ingabuye ihlukaniswe ngezigaba ezilandelayo ngokuya ngokusetshenziswa kanye nesimo:

1. Phambana ngekhanda le-pan eline-recessed self-drilling kanye nezikulufu zokuthepha. Izikulufu zokubhoboza ekhanda le-pan elinesikulufa ngokuthepha ngentambo yesikulufu Izinga Lokusebenza: I-GB/T 15856.1-2002 inokucaciswa okulandelayo: (ebuye ibizwe ngokuthi umsila oyindilinga wokubhoboza wekhanda).

2. I-counter-recessed countersunk head self-drilling kanye nezikulufu zokuthepha. Izikulufu zokubhoboza zekhanda eziphambanayo ezinezikulufa zokuchofa ngokuchofoza Izinga lokuqalisa: I-GB/T 15856.2-2002 inezincazelo ezilandelayo: (eyaziwa nangokuthi umsila wokubhoboza wekhanda eliyisicaba, umsila wesaladi wokubhoboza ikhanda).

3. Izikulufu ze-hexagon flange zekhanda ezinezikulufu zokuthepha. Izinga lokusetshenziswa: GB/T 15856.4-2002. Inokucaciswa okulandelayo: (ebuye ibizwe nge-hexagonal Dahua drill tail, okungesinye sezikulufu zomsila wokubhoboza. Ukucaciswa okuvame ukusetshenziswa kakhulu nokukhulu kakhulu.)

4. Ihexagon washer ekhanda izikulufu zokubhoboza ezinezikulufa zokuthepha. Izinga lokusetshenziswa: GB/T 15856.5-2002. Inokucaciswa okulandelayo: (ebuye ibizwe ngokuthi umsila wewasha oyi-hexagonal omncane.)
