Iluphi uhlobo lwensimbi nensimbi lufanele izikulufu zesokhethi ze-hex zebanga le-12.9 langempela

Ibanga 12.9 amabhawodi nezikulufi bheka izikulufu zamandla aphezulu kakhulu ezenziwe nge-35CrMo, 42CrMo, kanye nezinto zensimbi yengxubevange ye-B7, ezinamandla amancane aqinile angu-1220Mpa kanye nobulukhuni obungu-39-44HRC. Isetshenziswa kakhulu ezimbonini zendwangu, i-hydraulic, i-injection molding, kanye nezimboni zemishini ekhaya.

1. Isikulufu sebanga le-12.9 sisho isikulufu samandla aphezulu kakhulu esenziwe ngezinto zensimbi yengxubevange ye-SCM435, esinamandla amancane okubamba angu-1220Mpa kanye nobulukhuni obungu-39-44HRC. Isetshenziswa kakhulu ezimbonini zendwangu, i-hydraulic, i-injection molding, kanye nezimboni zemishini ekhaya.

2. Ngokusho kwento, ingahlukaniswa ngezinhlobo ezahlukene ezifana12.9 amabhawodi angaphandle angama-hexagonal, 12.9 ibangaizikulufu zekhanda ezingama-hexagonal zangaphakathi(ikhanda lenkomishi), izikulufu eziyi-hexagonal zebanga elingu-10.9 (inkomishi eyisicaba), izikulufu eziyindilinga ezine-hexagonal yebanga elingu-10.9 (inkomishi eyisiyingi), izikulufu zesethi yebanga elingu-12.9 (imitha yomshini), izikulufu zepulaki ezingama-hexagonal zebanga elingu-12.9, njll. Ngokusho intambo, ihlukaniswe yaba intambo eqinile, intambo enhle, i-metric, iBrithani, iMelika, njll.

3. Ibanga le-12.9 izinhlobonhlobo eziphezulu zezikulufi, ezinokuqina okuphezulu namandla aqinile. Ukuqina kwayo kwe-Rockwell (HRC) kungafinyelela ku-39-44, futhi amandla ayo aqinile angafinyelela ku-1220N/mm2. Kodwa-ke, ngenxa yomumo ohlukene wokukhiqiza isikulufu, izikulufu ze-hex ezishisiwe (izinkomishi eziyisicaba) kanye nezikulufu ze-hex ezinekhanda eliyindilinga (izinkomishi eziyindilinga) ezikhiqizwe ngento efanayo zingafinyelela kuphela amandla amancane okunyakazisa webanga le-10.9. Ingakwazi futhi ukuhlangabezana ngokugcwele nezidingo eziphakeme zezinkampani zezimboni nezimayini zokubopha ngezikhathi ezikhethekile nezingxenye.

I-Ningbo Zhongli bolts Production Co.ltd inikeza kuphela ibanga langempela le-12.9I-Hex socket screws DIN912ISO4762, ifektri ineminyaka engu-21 isipiliyoni sokukhiqiza.
