Izinyathelo zokuvimbela ukuphulwa kwezikulufu zokuzibhoboza
Ukuphuka kwekepisi eliphukile, umsila ophukile, induku ephukile, ngokuvamile kwenzeka ku-martensitic carbon steel self-drilling screw, i-martensitic carbon steel self-drilling screw ngokusebenzisa izinga lokushisa eliphezulu le-carbonitriding ebusweni ubulukhuni bufinyelele ku-≥560HV, nokungena okuqinile, kodwa futhi kwandise ukubola kwesikulufu. Lapho i-self-drilling screw esimweni somthwalo oweqile, i-torque eyeqile, ukudlidliza okulula kuzokwenzeka isenzakalo se-brittle fracture.Lapho i-self-drilling iphuka, ngeke nje ithinte inqubekelaphambili yokwakhiwa, hhayi enhle, kodwa futhi ilethe uchungechunge lwezingozi zokuphepha. Kukhona ikakhulukazi izici ezilandelayo zokuvimbela ukuphuka kwesikulufu sokumba:
1: Khetha umkhiqizo olungile
a: Ngaphambi kokusetshenziswa, qinisekisa ukuthi izakhiwo zomshini zomkhiqizo zingahlangabezana nezidingo zokusebenzisa
b: Ukukhetha okunengqondo kosayizi wesikulufa nobude
C: Kunconywa ukusebenzisa izinyo elinguhhafu noma umkhiqizo wezinyo eliphindwe kabili endaweni ye-interlayer
2: Sebenzisa inombolo
A: Sebenzisa izikulufu ezingu-4-6 ngemitha yesikwele ngayinye
B: Inani lophahla kanye nepuleti elisindayo kufanele likhuliswe ngendlela efanele
C: Indawo yomoya inkulu efanelekile yokwenyusa umthamo
3: Indlela yokusetshenziswa efanele
A: Thepha i-perpendicular ku-eksisi yochungechunge, ungatsheki
B: Enqubweni yokuqinisa, amandla kufanele afane, futhi i-torque yokuqinisa akufanele idlule i-torque yokuphepha.
C: 12 #, 14 # imikhiqizo yokucaciswa, isivinini sokuprakthiza kagesi 1000-1800 revolution ayikwazi ukushesha kakhulu
4: I-torque yokwehluleka (ngezansi kwedatha yereferensi kuphela) iyunithi:Nm
| imininingwane | Bhubhisa i-torque min |
| 4# | 1.5 |
| 6# | 2.8 |
| 8# | 4.7 |
| 10# | 6.9 |
| 12# | 10.4 |
| 14# | 16.9 |
