Njira zodzitetezera kuti zisasweke zomangira zodzibowolera
Kusweka kwa chipewa chosweka, mchira wosweka, ndodo yosweka, nthawi zambiri kumachitika mu screw ya martensitic carbon steel self drilling, screw ya martensitic carbon steel self drilling kudzera kutentha kwakukulu carbonitriding pamwamba kufika ≥560HV, ndi kulowa mwamphamvu, komanso kumawonjezera kufooka kwa screw. Pamene screw yodzibowola yokha ikakhala yolemera kwambiri, torque yochulukirapo, kugwedezeka kosavuta kumachitika chifukwa cha kusweka kwa brittle. Pamene kudzibowola kusweka, sikungokhudza kupita patsogolo kwa zomangamanga, sikukongola, komanso kumabweretsa zoopsa zingapo zachitetezo. Pali zinthu zotsatirazi zomwe zimaletsa kusweka kwa screw yobowola:
1: Sankhani chinthu choyenera
a: Musanagwiritse ntchito, tsimikizirani ngati mawonekedwe a makina a chinthucho angakwaniritse zofunikira pakugwiritsa ntchito.
b: Kusankha koyenera kwa kukula ndi kutalika kwa screw
C: Ndikoyenera kugwiritsa ntchito mankhwala a theka la mano kapena mano awiri m'malo ozungulira
2: Gwiritsani ntchito nambalayi
A: Gwiritsani ntchito zomangira 4-6 pa mita imodzi
B: Chiwerengero cha denga ndi mbale zolemera ziyenera kuwonjezeredwa moyenera
C: Malo olowera mphepo ndi akulu koyenera kuwonjezera mlingo
3: Njira yogwiritsira ntchito moyenera
A: Dinani molunjika ku mzere wa ulusi, musapendeke
B: Pakulimbitsa, mphamvu iyenera kukhala yofanana, ndipo mphamvu yolimbitsa siyenera kupitirira mphamvu yotetezeka
C: 12#, 14# zinthu zofotokozera, liwiro la kubowola kwamagetsi 1000-1800 singakhale lachangu kwambiri
4: Mphamvu yolephera (pansi pa deta yongogwiritsidwa ntchito kokha) gawo:Nm
