I-Torx Drive Countersunk Chipboard Screw Zinc Ifakwe ngeSaw Thread

I-Chipboard Screw:

1. Ukunyanga ukushisa: Yindlela yokufudumeza intsimbi kumaqondo ahlukeneyo kwaye emva koko usebenzisa iindlela zokupholisa ezahlukeneyo ukufezekisa iinjongo ezahlukeneyo zokutshintsha iimpawu zentsimbi.Unyango oluqhelekileyo olusetyenziswayo lobushushu ngala: ukucinywa, ukutshisa, kunye nokuthoba.Ziziphi iziphumo eziya kuvelisa ezi ndlela zintathu?

2. Ukucima: Indlela yokucoca ubushushu apho intsimbi ifudunyezwa ngaphezu kwe-942 degrees Celsius ukwenza iikristale zentsimbi kwi-austenitic state, kwaye emva koko ifakwe emanzini abandayo okanye ioli yokupholisa ukucima ukwenza iikristali zentsimbi kwimeko ye-martensitic.Le ndlela inokunyusa amandla kunye nobunzima bentsimbi.Kukho umehluko omkhulu kakhulu kumandla kunye nobunzima bentsimbi kunye nelebula efanayo emva kokucima kwaye ngaphandle kokucima.

3. I-Anealing: Indlela yonyango lobushushu apho intsimbi iphinda ifudunyezwe kwi-austenitic state kwaye ipholiswe ngokwemvelo emoyeni.Le ndlela inokunciphisa amandla kunye nobunzima bentsimbi, iphucule ukuguquguquka kwayo, kwaye iququzelele ukusetyenzwa.Ngokuqhelekileyo, intsimbi iya kuhamba ngeli nyathelo ngaphambi kokuba iqhutywe.

4. I-Tempering: Ingaba iyacinywa, i-annealed okanye i-press-formed, insimbi iya kuvelisa uxinzelelo lwangaphakathi, kwaye ukungalingani koxinzelelo lwangaphakathi kuya kuchaphazela isakhiwo kunye neempawu zomatshini zetsimbi ukusuka ngaphakathi, ngoko kufuneka inkqubo yokufudumala.Izinto eziphathekayo zigcinwa zifudumele ngokuqhubekayo kwiqondo lokushisa elingaphezu kwama-700 degrees, uxinzelelo lwangaphakathi lutshintshwa kwaye lupholile ngokwemvelo.
