Luluphi uhlobo lwentsimbi kunye nentsimbi efanelekileyo kwibakala lokwenyani le-12.9 hex socket screws

IBakala 12.9 iibholiti kunye nezikrufu bhekisa kwi-ultra high-screws zamandla ezenziwe nge-35CrMo, 42CrMo, kunye ne-B7 ye-alloy yensimbi ye-alloy, kunye namandla amancinci angama-1220Mpa kunye nobunzima be-39-44HRC. Isetyenziswa ikakhulu kwimpahla yelaphu, ihydraulic, isitofu sokubumba, kunye namashishini oomatshini ekhaya.

1. I-screw ye-12.9 grade ibhekisela kwi-screw yamandla e-ultra-high eyenziwe nge-SCM435 i-alloy material yensimbi, kunye namandla amancinci angama-1220Mpa kunye nobunzima be-39-44HRC. Isetyenziswa ikakhulu kwimpahla yelaphu, ihydraulic, isitofu sokubumba, kunye namashishini oomatshini ekhaya.

2. Ngokwento leyo, inokwahlulwa ibe ziindidi ezahlukeneyo ezifana12.9 iibholithi zangaphandle ezinehexagonal, 12.9 ibakalaizikrufu zentloko zehexagonal zangaphakathi(intloko indebe), 10.9 grade countersunk intloko izikrufu hexagonal yangaphakathi (indebe flat), 10.9 grade semi ngeenxa zonke intloko izikrufu zehexagonal yangaphakathi (indebe engqukuva), 12.9 grade set izikrufu (umatshini imitha), 12.9 ibakala yangaphakathi iplagi izikrufu, njl intambo, yohlulwe ibe yintambo erhabaxa, intambo entle, imetriki, iBritane, iMelika, njl.

3. IBakala 12.9 lolona didi luphezulu lwezikrufu, ezinobulukhuni obuphezulu kunye nokomelela kokuqina. Ubunzima bayo be-Rockwell (HRC) bunokufikelela kwi-39-44, kwaye amandla ayo anamandla anokufikelela kwi-1220N / mm2. Nangona kunjalo, ngenxa yeemilo ezahlukeneyo zokwenza izikrufu, izikrufu zeheksi ezishiyiweyo (iikomityi ezisicaba) kunye nezikrufu zeheksi ezinentloko engqukuva (iikomityi ezingqukuva) eziveliswe kwinto enye zinokufikelela kuphela awona mandla asezantsi e-hex ebanga le-10.9. Inokuthi ihlangabezane ngokupheleleyo neemfuno eziphezulu zamashishini kunye nemigodi ye-fasteners kwizihlandlo ezikhethekileyo kunye namacandelo.

I-Ningbo Zhongli ibholithi yokuvelisa i-co.ltd ibonelela kuphela ibakala lokwenyani le-12.9Hex socket screws DIN912ISO4762, umzi-mveliso uneminyaka engama-21 yamava emveliso.
