Chiyambi cha Zomangira-2

4. Chithunzi cha Zigawo za Bolt

5. Kuzindikira Bolt

6. Zizindikiro, Magiredi Ogwira Ntchito, ndi zina zotero.

1. Zizindikiro: Pa maboliti ndi zomangira za hexagonal (m'mimba mwake wa ulusi >5mm), zizindikiro ziyenera kupangidwa pamwamba pa mutu pogwiritsa ntchito zilembo zokwezedwa kapena zobisika, kapena kumbali ya mutu pogwiritsa ntchito zilembo zobisika. Izi zikuphatikizapo magiredi a magwiridwe antchito ndi zizindikiro za wopanga. Pa chitsulo cha carbon: Khodi yolembera mphamvu imapangidwa ndi magulu awiri a manambala olekanitsidwa ndi "·". Tanthauzo la gawo la nambala patsogolo pa "·" mu code yolembera limasonyeza mphamvu yokhazikika. Mwachitsanzo, "4" mu giredi 4.8 imasonyeza mphamvu yomangirira ya 400N/mm2, kapena 1/100 ya iyo. Tanthauzo la gawo la nambala pambuyo pa "·" mu giredi yolembera limasonyeza chiŵerengero cha yield-to-tensile, chomwe ndi chiŵerengero cha mfundo yomangira ya nomine kapena mphamvu yomangira ya nomine ku mphamvu yomangira ya nomine. Mwachitsanzo, mfundo yomangira ya chinthu cha giredi 4.8 ndi 320N/mm2. Zizindikiro za mphamvu ya chinthu chachitsulo chosapanga dzimbiri zimapangidwa ndi magawo awiri olekanitsidwa ndi "-". Chizindikiro chisanafike "-" mu giredi yolembera chimasonyeza zinthuzo, monga A2, A4, ndi zina zotero. Chizindikiro pambuyo pa "-" chimasonyeza mphamvu, monga A2-70.

2). Giredi: Pa chitsulo cha carbon, magiredi a magwiridwe antchito a makina a metric bolt amatha kugawidwa m'magiredi 10 a magwiridwe antchito: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, ndi 12.9. Chitsulo chosapanga dzimbiri chimagawidwa m'magulu atatu: 60, 70, 80 (austenitic); 50, 70, 80, 110 (martensitic); 45, 60 (ferritic).

7. Chithandizo cha pamwamba

Kukonza pamwamba makamaka kumafuna kuonjezera kukana dzimbiri, ndipo ena amaganiziranso za utoto, kotero makamaka ndi zinthu zopangidwa ndi chitsulo cha kaboni, zomwe nthawi zambiri zimafuna kukonzedwa pamwamba. Kukonza pamwamba kofala kumaphatikizapo kufinya, kuyika galvanizing, kuyika mkuwa, kuyika nickel, kuyika chrome, kuyika siliva, kuyika golide, kuyika dacromet, kuyika galvanizing yotentha, ndi zina zotero; pali mitundu yambiri ya kuyika galvanizing, monga zinc yabuluu ndi yoyera, zinc yabuluu, zinc yoyera, zinc yachikasu, zinc yakuda, zinc yobiriwira, ndi zina zotero, ndipo zimagawidwanso m'mitundu yosamalira chilengedwe komanso yosasamalira chilengedwe. Gulu lililonse lili ndi makulidwe angapo ophimba kuti akwaniritse zofunikira zosiyanasiyana zoyesera mchere.

Chidule cha Zogulitsa Zazigawo Zagalimoto Zokhazikika

1). Chidule cha Zigawo Zoyenera za Magalimoto

Zigawo zokhazikika zamagalimoto zili ndi mitundu yosiyanasiyana ndipo zimagwiritsidwa ntchito popanga zida zosiyanasiyana zamagalimoto, komanso kulumikizana ndi kusonkhanitsa ma subsystem osiyanasiyana kuti apange galimoto yonse. Ubwino wa zigawo zokhazikika umakhudza kwambiri ubwino ndi magwiridwe antchito a zida zamakanika, ndipo opanga magalimoto nthawi zambiri amakhala ndi njira zowunikira mozama komanso miyezo yotsimikizira makina olumikizira. Kukula kwakukulu kwa msika wamagalimoto kumapereka malo ambiri okulirapo opangira zida zokhazikika zamagalimoto. Malinga ndi ziwerengero, galimoto yopepuka kapena yonyamula anthu imafuna pafupifupi 50kg (pafupifupi zidutswa 5,000), pomwe galimoto yamalonda yapakatikati kapena yolemera imafuna pafupifupi 90kg (pafupifupi zidutswa 5,710).

2). Manambala Oyenera a Zigawo za Magalimoto

Wopanga injini wamkulu aliyense mumakampani opanga magalimoto amagwiritsa ntchito "Malamulo Owerengera Zinthu Zagalimoto Okhazikika" (QC/T 326-2013) kuti apange zofunikira pakuwunika manambala azinthu zamakampani, ndipo zomwe zili mkati mwake zimakhalabe chimodzimodzi ngakhale pali kusiyana.

Manambala a zigawo zokhazikika zamagalimoto nthawi zambiri amakhala ndi magawo 7, motsatira izi:

- Gawo 1: Khodi ya zida zoyezera magalimoto;
- Gawo 2: Khodi yosiyana;
- Gawo 3: Sinthani khodi (ngati mukufuna);
- Gawo 4: Khodi yofotokozera za miyeso;
- Gawo 5: Kagwiridwe ka ntchito ka makina kapena mfundo za zinthu;
- Gawo 6: Khodi yochizira pamwamba;
- Gawo 7: Khodi yogawa (ngati mukufuna).

Chitsanzo: Q150B1250TF61 ikuyimira boluti ya mutu wa hexagonal yokhala ndi ulusi wa M12, kutalika kwa boluti ya 50mm, giredi yogwira ntchito ya 10.9, ndi chophimba cha zinc chosakhala cha electrolytic (siliva-imvi). Njira yowonetsera ndi iyi:
