Matanho ekudzivirira kubva pakutyoka kwe self drilling screws
Kutyoka kwekepisi yakatyoka, muswe wakatyoka, tsvimbo yakatyoka, inowanzoitika mumartensitic carbon steel self drilling screw, martensitic carbon steel self drilling screw kuburikidza nepamusoro tembiricha carbonitriding pamusoro kuoma kwakasvika ≥560HV, nekupinda kwakasimba, asi zvakare yakawedzera brittleness ye screw. Kana iyo self drilling sikuruu kana yakawandisa mutoro, yakawandisa torque, nyore vibration zvichaitika brittle fracture phenomenon.Kana self drilling breaks, hazvizongokanganisa kufambira mberi kwekuvaka, kwete kunaka, asiwo kuunza nhevedzano yenjodzi dzekuchengetedza. Iko kune zvakanyanya zvinotevera zvinhu zvekudzivirira kutyoka kwedrilling screw:
1: Sarudza chigadzirwa chakakodzera
a: Usati washandisa, simbisa kana michina yechigadzirwa ichigona kuzadzisa zvinodiwa zvekushandisa
b: Inonzwisisika kusarudzwa kwehukuru hwekukurisa uye kureba
C: Inokurudzirwa kushandisa hafu zino kana kaviri mazino chigadzirwa munzvimbo ye interlayer
2: Shandisa nhamba
A: Shandisa 4-6 screws pa square mita
B: Nhamba yedenga uye ndiro inorema inofanira kuwedzerwa zvakakodzera
C: Mhepo nzvimbo yakakura yakakodzera kuwedzera dosage
3: Nzira yekushandisa kwayo
A: Tinya perpendicular kune axis yeshinda, usarerekera
B: Mukuita kwekusimbisa, simba rinofanira kunge rakafanana, uye torque yekusimbisa haifanirwe kudarika iyo yekuchengetedza torque.
C: 12 #, 14 # zvakatemwa zvigadzirwa, yemagetsi chibooreso kumhanya 1000-1800 chimurenga haigoni kukurumidza
4: Kutadza torque (pazasi data rereferensi chete) unit:Nm
| tsanangudzo | Paradzai torque min |
| 4# | 1.5 |
| 6# | 2.8 |
| 8# | 4.7 |
| 10# | 6.9 |
| 12# | 10.4 |
| 14# | 16.9 |
