I-truss head self-drilling screws
Izikulufu ze-truss izikulufu ezinomumo othile kanye nemisebenzi, ngokuvamile esetshenziselwa ukuxhuma izingxenye ezihlukahlukene zesakhiwo se-truss. Zisetshenziswa kabanzi kubunjiniyela bemishini, ubunjiniyela bezokwakha, i-aerospace neminye imikhakha. Ukuma nosayizi wabo ngokuvamile kubenza bafaneleke kakhulu ekuxhumekeni kwe-truss.
Izikulufu ze-truss ngokuvamile zenziwe ngensimbi eqinile ye-alloy, insimbi engagqwali, i-titanium alloy nezinye izinto zokuqinisekisa ukuthi zingakwazi ukumelana nemithwalo ephezulu futhi ngeke zibe nokugqwala noma ezinye izinkinga ngesikhathi sokusetshenziswa isikhathi eside.
Izikulufu ze-truss ziyizixhumi ezibalulekile ekwakhiweni kwesakhiwo se-truss. Zinemisebenzi elandelayo:
1. Xhuma izingxenye ezihlukahlukene zesakhiwo se-truss;
2. Ukuthuthukisa ukuzinza nokuqina kwesakhiwo se-truss;
3. Nikeza ukuxhumana okuthembeke kakhulu ezinhlelweni ezihlukahlukene zobunjiniyela.
Izici ezibalulekile ekukhetheni izikulufu ezifanele ze-truss umthwalo, ingcindezi, nendawo. Uma amandla okubamba emakhulu, usayizi wesikulufa esikhulu udinga ukukhethwa ukuze uhlangabezane nezidingo ngaphansi kwezimo zomthwalo ophezulu. Ezindaweni zasolwandle, ezonakalisayo, nakwezinye ezinokhahlo, kubalulekile ukukhetha izinto eziqinile njengensimbi engagqwali noma ama-titanium alloys ahlangabezana nezidingo.
Izikulufu ze-truss zingenye yezingxenye eziyinhloko ezixhuma izakhiwo ze-truss, ezivame ukusetshenziswa ekwakheni amapulatifomu, izigaba, izitendi zemibukiso, nezinye izikhathi. Ukucaciswa kwayo kufaka phakathi ububanzi bentambo, ubude, iphimbo, i-material, nezinye izici.
① Ububanzi bochungechunge
I-diameter yentambo yezikulufi ze-truss ingahlukaniswa ngezinhlobo zezintambo ezijwayelekile nezicolile, ngokuvamile i-M8, M10, M12, njll. Uhlobo lwentambo enhle lulungiswa kancane ngesisekelo sohlobo olujwayelekile ukuze kuthuthukiswe ukuzinza koxhumano.
②Ubude
Ubude bezikulufu ze-truss ngokuvamile buphakathi kuka-20mm no-200mm, obuhlobene nobude besakhiwo se-truss futhi udinga ukukhethwa ngokuya ngesimo sangempela.
③ Iphimbo lochungechunge
Ukuphakama kwezikulufu ze-truss ngokuvamile kungu-1.5mm~2.0mm, futhi uma iphimbo lincane, kulapho uxhumano luqina khona.
④ Okubalulekile
Ngokuvamile kunezinhlobo ezimbili zezinto zokwakha izikulufi ze-truss: i-carbon steel nensimbi engagqwali. Insimbi engagqwali inempilo ende yesevisi kanye nokumelana nokugqwala okungcono, kodwa intengo ehambisanayo nayo iphakeme.
