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

Ibanga 12.9 amabhawodi nezikulufibheka 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(inkomishi inkomishi), 10.9 grade countersunk ikhanda yangaphakathi ngezikulufi ezinehexagonal (inkomishi flat), 10.9 grade semi round ikhanda izikulufi ezinehexagonal yangaphakathi (inkomishi round), 12.9 grade set ngezikulufo (imitha umshini), 12.9 grade yangaphakathi hexagonal ipulaki ngezikulufo, njll Ngokusho intambo, it ihlukaniswe, intambo British, metric, njll American.

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 ohlukile 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 12.9Izikulufo zesokhethi ze-Hex DIN912ISO4762, ifektri ineminyaka engu-21 isipiliyoni sokukhiqiza.
