Amanyathelo othintelo ngokuchasene nokophuka kwezikrufu zokuzibhora
Ukwaphuka kwekepusi eyaphukileyo, umsila owaphukileyo, intonga eyaphukileyo, kaninzi kwenzeka kwi-martensitic carbon steel self-drilling screw, martensitic carbon steel self-drilling screw ngokusebenzisa ubushushu obuphezulu be-carbonitriding surface hardness ifike ku-≥560HV, kunye nokungena olomeleleyo, kodwa kwakhona kwandise ubuqhophololo besikrufu. Xa i-self-drilling screw kwimeko yomthwalo ogqithisileyo, i-torque egqithisileyo, i-vibration elula iya kwenzeka i-brittle fracture phenomenon.Xa i-self-drilling breaks, ayiyi kuchaphazela kuphela inkqubela phambili yokwakhiwa, intle, kodwa iphinde izise uluhlu lweengozi zokhuseleko. Kukho ikakhulu le miba ilandelayo ukuthintela ukophuka kwesikrufu sokomba:
1: Khetha imveliso efanelekileyo
a: Phambi kokusetyenziswa, qinisekisa ukuba iipropathi zomatshini zemveliso zinokuhlangabezana neemfuno zokusetyenziswa
b: Ukukhetha okunengqiqo kobukhulu besijija kunye nobude
C: Kucetyiswa ukuba usebenzise isiqingatha sezinyo okanye imveliso yezinyo kabini kwindawo ye-interlayer
2: Sebenzisa inombolo
A: Sebenzisa izikrufu ezi-4-6 ngemitha yesikwere
B: Inani lephahla kunye nepleyiti enzima kufuneka linyuswe ngokufanelekileyo
C: Indawo yomoya inkulu ngokufanelekileyo yonyuselo lwedosi
3: Indlela echanekileyo yokusetyenziswa
A: Thepha ngokuthe ngqo kwi-axis yomsonto, musa ukutyekela
B: Kwinkqubo yokuqinisa, amandla kufuneka afane, kwaye i-torque yokuqinisa akufanele idlule i-torque yokhuseleko.
C: 12 #, 14 # iimveliso ezibalulwe, isantya sombane 1000-1800 revolution ayikwazi ukuba ngokukhawuleza kakhulu
4: Itorque yokusilela (ngaphantsi kwedatha yereferensi kuphela) iyunithi:Nm
