4. Kiʻikuhi ʻĀpana Bolt

5. Ka ʻike ʻana i ka ʻūlū

6. Nā Māka, Nā Māka Hana, a pēlā aku.

1. Nā Māka: No nā ʻōwili hexagonal a me nā wili (ke anawaena o ke kaula >5mm), pono e hana ʻia nā māka ma ka ʻili luna o ke poʻo me ka hoʻohana ʻana i nā leka i hāpai ʻia a i ʻole i hoʻihoʻi ʻia, a i ʻole ma ka ʻaoʻao o ke poʻo me ka hoʻohana ʻana i nā leka i hoʻihoʻi ʻia. Hoʻokomo pū kēia i nā māka hana a me nā māka a ka mea hana. No ke kila kalapona: Ua haku ʻia ke code māka māka ikaika i ʻelua mau seti o nā helu i hoʻokaʻawale ʻia e kahi "·". ʻO ke ʻano o ka ʻāpana helu ma mua o ka "·" i loko o ke code māka e hōʻike ana 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 ia mea. ʻO ke ʻano o ka ʻāpana helu ma hope o ka "·" i loko o ke code hōʻailona e hōʻike ana i ka lakio yield-to-tensile, ʻo ia ka lakio o ka nominal yield point a i ʻole ka nominal yield strength i ka nominal tensile strength. No ka laʻana, ʻo ke kiko yield o ka huahana 4.8 he 320N/mm2. Ua haku ʻia nā māka papa ikaika huahana kila kila i ʻelua ʻāpana i hoʻokaʻawale ʻia e "-". ʻO ka hōʻailona ma mua o ka "-" i loko o ke code hōʻailona e hōʻike ana i ka mea, e like me A2, A4, a pēlā aku. ʻO ka hōʻailona ma hope o ka "-" e hōʻike ana i ka ikaika, e like me A2-70.

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

7. Ka mālama ʻana i ka ʻili

ʻO ka mālama ʻana i ka ʻili, ʻo ia ke hoʻonui i ke kūpaʻa ʻana i ka pala, a noʻonoʻo kekahi i ke kala, no laila, ʻo ia ke kumu nui no nā huahana kila kalapona, ka mea maʻamau e pono ai ka mālama ʻana i ka ʻili. ʻO nā mālama ʻili maʻamau e pili ana i ka ʻeleʻele, ka galvanizing, ke keleawe plating, ka nickel plating, ka chrome plating, ke kālā plating, ke gula plating, dacromet, ka hoʻoluʻu wela galvanizing, a pēlā aku; he nui nā ʻano galvanizing, e like me ka zinc polū a me ke keʻokeʻo, ka zinc polū, ka zinc keʻokeʻo, ka zinc melemele, ka zinc ʻeleʻele, ka zinc ʻōmaʻomaʻo, a pēlā aku, a ua hoʻokaʻawale ʻia hoʻi lākou i nā ʻano aloha kaiapuni a me nā ʻano aloha ʻole i ke kaiapuni. Loaʻa i kēlā me kēia māhele nā ​​mānoanoa uhi he nui e hoʻokō ai i nā koi hoʻāʻo pīpī paʻakai like ʻole.

ʻIkepili o nā Huahana ʻĀpana Maʻamau o ke Kaʻa

1). ʻIkepili o nā ʻĀpana Maʻamau o ke Kaʻa

He ʻano like ʻole nā ​​ʻāpana maʻamau o ke kaʻa a hoʻohana ʻia i ka hana kikoʻī o nā ʻāpana like ʻole a me nā ʻāpana o nā kaʻa, a me ka hoʻopili ʻana a me ka ʻākoakoa ʻana o nā ʻōnaehana like ʻole e hana i ke 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 he mau ʻano loiloi koʻikoʻi a me nā kūlana hōʻoia no nā ʻōnaehana hoʻolako paʻa. ʻO ka nui o ka mākeke o ka ʻoihana kaʻa e hāʻawi i kahi ākea ākea no nā huahana ʻāpana maʻamau o ke kaʻa. Wahi a nā helu helu, pono kahi kaʻa māmā a kaʻa paha ma kahi o 50kg (ma kahi o 5,000 ʻāpana) o nā ʻāpana maʻamau, ʻoiai ʻo kahi kaʻa kalepa waena a kaumaha paha e pono ai ma kahi o 90kg (ma kahi o 5,710 ʻāpana).

2). Ka Helu ʻana i nā ʻĀpana Maʻamau o ke Kaʻa

Hoʻohana kēlā me kēia mea hana ʻenekini nui i ka ʻoihana kaʻa i ke kūlana maʻamau "Automotive Standard Parts Product Numbering Rules" (QC/T 326-2013) e hoʻokumu i nā kikoʻī no ka helu ʻana i nā ʻāpana maʻamau o ka ʻoihana, a ua like mau ka ʻike me nā ʻokoʻa.

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

- Māhele 1: Kōmike hiʻona ʻāpana maʻamau o ke kaʻa;
- Māhele 2: Kōmike ʻano like ʻole;
- Māhele 3: Hoʻololi i ke code (koho);
- Māhele 4: Kōmike kikoʻī ana;
- Māhele 5: Hana mīkini a i ʻole ke code mea;
- Māhele 6: Kōkuhi mālama ʻili;
- Māhele 7: Kōmike hoʻokaʻawale (koho).

Laʻana: Hōʻike ʻo Q150B1250TF61 i kahi wili poʻo hexagonal me kahi kikoʻī kaula o M12, kahi lōʻihi o ka wili he 50mm, kahi papa hana o 10.9, a me kahi uhi zinc non-electrolytic (hina-kala). Penei ke ʻano hōʻike:
