I-Screw fasteners idlala indima ebalulekileyo kumashishini ahlukeneyo kunye nezicelo, ukubonelela ngendlela ethembekileyo nesebenzayo yokujoyina izixhobo.
1. Ukubaluleka kwezikrufu:
Izikrufu zibalulekile kulo lonke ushishino, ukusuka kulwakhiwo kunye neemoto ukuya kwizinto zombane kunye nefanitshala. Ezi fasteners eziguquguqukayo zinika uxhulumaniso oluqinileyo, luqinisekisa ukuzinza kunye nokunyaniseka kwamacandelo adibeneyo. Ngokuqinisa ngokukhuselekileyo izinto ezahlukeneyo, izikrufu zenza iimveliso ezisebenzayo kunye nezizinzileyo.
2. Inkqubo yokwenziwa kwezikrufu:
Ukuveliswa kwezibophelelo zesikrufu kubandakanya amanyathelo asisiseko aliqela, kuquka:
a) Ukukhethwa kwezinto:
Abavelisi bakhetha ngononophelo imathiriyeli yesikrufu esifanelekileyo, bethathela ingqalelo izinto ezifana namandla, ukuxhathisa umhlwa, kunye nokufaneleka kwendawo ethile. Izinto eziqhelekileyo ziquka insimbi engenasici, i-carbon steel, i-aluminium, kunye nobhedu.
b) Imveliso yocingo:
Izinto ezikhethiweyo zenziwa ngocingo ngeenkqubo ezifana nokuqengqeleka okushushu okanye umzobo obandayo. Eli nyathelo liqinisekisa ngokungaguquguqukiyo, izithuba eziphakamileyo ze-screw ziveliswa.
c) Ubude:
Ucingo olungenanto lusikwe kubude obufunwayo kwaye lubunjwe kumatshini wesihloko. Le nkqubo ibumba intloko ye-screw kwaye iyilungiselele ukuguqulwa okulandelayo.
d) Ukulungiswa komsonto:
I-threading ibandakanya ukudala i-helical groove kwi-screw shaft evumela ukuba ingene kwaye ibandakanye icandelo elihambelanayo. Oku kunokufezekiswa ngeendlela ezifana nokuqengqeleka kwentambo, ukusika intambo okanye ukwenza intambo.
e) Unyango lobushushu kunye nokwaleka:
Ukuze kwandiswe iipropathi zoomatshini kunye nokunganyangeki komhlwa, izikrufu zihlala ziphantsi kweenkqubo zonyango lobushushu ezinje nge-annealing, quenching, and tempering. Ukongeza, iingubo ezinje ngegalvanized, galvanized or organic coatings zisetyenziselwa ukubonelela ngokhuseleko olungaphezulu lokuhlwa.
f) Ukuhlolwa nokupakishwa:
Phambi kokupakishwa, izikrufu zihlolwa kumgangatho ongqongqo ukuqinisekisa ukuchaneka komda, amandla kunye nokugqiba komphezulu. Emva kokuba zivunyiwe, zipakishwa ngobuninzi okanye ubuninzi obuthile, zilungele ukuhanjiswa.

3. Imfuno yemarike yezikrufu:
Imfuno yentengiso yezikrufu iyaqhubeka ukuba namandla ngenxa yezi zizathu zilandelayo:
a) Ukukhula kwamashishini:
Njengoko imizi-mveliso efana neyokwakha, iimoto kunye ne-elektroniki isanda kwihlabathi jikelele, imfuno yezisombululo ezithembekileyo nezisebenzayo zokuqinisa iye yanda. Izikrufu zibonelela ngezinto ezahlukeneyo kunye neendlela ezinokwenziwa ngokwezifiso ukuhlangabezana nezi mfuno kuwo wonke amashishini.
b) Ukulungiswa nokugcinwa:
Njengoko izixhobo ezikhoyo kunye nezixhobo zifuna ukulungiswa okanye ukuphuculwa, imfuno yezikrufu iba yinto ebalulekileyo. I-Fasteners idlala indima ebalulekileyo ekugcinweni nasekuphileni ixesha elide koomatshini, iqinisekisa ukusebenza kakuhle kunye nokuthintela ukuchithwa kweendleko.
Shwankathela:
Inkqubo yokwenziwa kwe-screw fasteners ibandakanya ingqalelo ecokisekileyo ekukhetheni izinto, ukwenziwa kunye nokugqiba. Izikrufu zidlala indima ebalulekileyo ekuboneleleni ngoqhagamshelo olukhuselekileyo kunye nokuzalisekisa iimfuno zamashishini ahlukeneyo kwaye ngenxa yoko zihlala ziyimveliso esisiseko kwizicelo ezingenakubalwa.
