4. Kiʻi ʻāpana Bolt

5. ʻIkepili Bolt

6. Hoailona, ​​Papa Hana, etc.

1. Nā hōʻailona: No nā kī hexagonal a me nā wili (ke anawaena o ke kaula >5mm), pono e hana ʻia nā kaha ma ka ʻaoʻao o luna o ke poʻo me ka hoʻohana ʻana i nā leka i hoʻokiʻekiʻe ʻia a i ʻole, a i ʻole ma ka ʻaoʻao o ke poʻo me nā leka hoʻomaha. Loaʻa kēia i nā māka hana a me nā māka hana. No ke kila kalapona: Ua haku ʻia ka helu kaha mākaʻikaʻi me ʻelua pūʻulu helu i hoʻokaʻawale ʻia e kahi “·”. ʻO ka manaʻo o ka hapa helu ma mua o ka "·" ma ke code marking e hōʻike i ka ikaika tensile nominal. No ka laʻana, ʻo ka “4″ ma ka papa 4.8 e hōʻike ana i ka ikaika tensile nominal o 400N/mm2, a i ʻole 1/100 o kēlā. ʻO ka manaʻo o ka hapa helu ma hope o ka "·" ma ke code marking e hōʻike ana i ka ratio yield-to-tensile, ʻo ia ka ratio o ka helu hua inoa a i ʻole ka ikaika hāʻawi inoa i ka ikaika tensile nominal. No ka laʻana, ʻo 320N/mm2 ka helu hua o ka huahana papa 4.8. Hoʻokumu ʻia nā hōʻailona ikaika o ka huahana kila kila i ʻelua ʻāpana i hoʻokaʻawale ʻia e "-". ʻO ka hōʻailona ma mua o ka "-" ma ke code marking e hōʻike i ka mea, e like me A2, A4, etc. ʻO ka hōʻailona ma hope o ka "-" hōʻike i ka ikaika, e like me A2-70.

2). Papa: No ke kila kalapona, hiki ke hoʻokaʻawale ʻia nā māka hana metric bolt mechanical i 10 mau māka hana: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, a me 12.9. Hoʻokaʻawale ʻia ke kila kila i ʻekolu mau ʻāpana: 60, 70, 80 (austenitic); 50, 70, 80, 110 (martensitic); 45, 60 (ferritic).

7. Lapaʻau ʻili

ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili ka mea nui e hoʻonui i ka pale ʻana i ka corrosion, a noʻonoʻo kekahi i ke kala, no laila ʻo ia ka mea maʻamau no nā huahana kalapona, ka mea maʻamau e koi ai i ka mālama ʻana. ʻO nā lāʻau lapaʻau maʻamau e pili ana i ka blackening, galvanizing, copper plating, nickel plating, chrome plating, silver plating, gula plating, dacromet, hot-dip galvanizing, etc.; he nui nā ʻano galvanizing, e like me ka zinc uliuli a me ke keʻokeʻo, ka zinc uliuli, ka zinc keʻokeʻo, ka zinc melemele, ka zinc ʻeleʻele, ka zinc ʻōmaʻomaʻo, a me nā mea ʻē aʻe, a ua hoʻokaʻawale ʻia lākou i loko o nā ʻano kūlohelohe a me nā ʻano pili ʻole. Loaʻa i kēlā me kēia ʻāpana nā mānoanoa uhi he nui e hoʻokō i nā koi hoʻāʻo paʻakai.

ʻO ka nānā ʻana o nā huahana ʻāpana maʻamau o ka automotive

1). Nānā o nā ʻāpana maʻamau kaʻa

Loaʻa i nā ʻāpana maʻamau o ka automotive nā ʻano ʻano like ʻole a hoʻohana ʻia i ka hana kikoʻī o nā ʻāpana like ʻole a me nā ʻāpana o nā kaʻa, a me ka pilina a me ka hui ʻana o nā subsystems like ʻole e hana i ka kaʻa holoʻokoʻa. He hopena koʻikoʻi ka maikaʻi o nā ʻāpana maʻamau i ka maikaʻi holoʻokoʻa a me ka hana o nā lako mīkini, a ʻo nā mea hana kaʻa maʻamau i loaʻa i nā mīkini loiloi koʻikoʻi a me nā kūlana hōʻoia no nā ʻōnaehana lako paʻa. Hāʻawi ka nui o ka mākeke nui o ka ʻoihana automotive i kahi ākea ākea no nā huahana ʻāpana maʻamau automotive. Wahi a nā helu helu, pono ke kaʻa māmā a i ʻole kaʻa kaʻa e pili ana i 50kg (ma kahi o 5,000 mau ʻāpana) o nā ʻāpana maʻamau, ʻoiai ke kaʻa kalepa ʻoi a kaumaha paha e pono ai ma kahi o 90kg (ma kahi o 5,710 mau ʻāpana).

2). Helu 'āpana maʻamau kaʻa

Ke hoʻohana nei kēlā me kēia mea hana ʻenekini nui i ka ʻoihana kaʻa i ka maʻamau "Automotive Standard Parts Product Numbering Rules" (QC/T 326-2013) no ka hoʻokumu ʻana i nā kikoʻī no ka helu ʻana i nā ʻāpana maʻamau o ka ʻoihana, a e mau ana ka ʻike me nā ʻano like ʻole.

ʻO ka helu ʻana i nā ʻāpana maʻamau o ka automotive he 7 mau ʻāpana, ma ke ʻano:

- Māhele 1: Nā ʻāpana maʻamau o nā ʻāpana kaʻa kaʻa;
- Māhele 2: Code like ʻole;
- Māhele 3: Hoʻololi i ke code (koho);
- Māhele 4: Ka helu kikoʻī kikoʻī;
- Māhele 5: Ka hana mīkini a i ʻole ke code waiwai;
- Māhele 6: Ke code lapaʻau ʻili;
- Māhele 7: Ka helu helu (koho).

Laʻana: Q150B1250TF61 e hōʻike ana i ke poʻo hexagonal me kahi kikoʻī o ke kaula o M12, ka lōʻihi o ka bolt o 50mm, kahi māka hana o 10.9, a me ka uhi ʻana i ka zinc non-electrolytic (kela-hina). ʻO ke ʻano o ka hōʻike ʻana penei:
