Bolt ndi Mtedza wa Gawo la Nsapato Yotsatizana Yotsatizana Yotsatizana Yotsatizana Yotsatizana

Kukula koyenera kwa boluti ndi mtedza wofukula zinthu zakale kumatha kusiyana kutengera mtundu ndi mtundu wa chofukula zinthu zakale. Kukula kofala ndi monga M12, M16, M20, ndi M24.

Gawo 1: Kuyang'anira ndi kusunga zinthu zopangira
Zipangizo zopangira bolt ziyenera kusankhidwa ndi wopanga malinga ndi momwe zagwiritsidwira ntchito. Zipangizo zoti zigwiritsidwe ntchito kuti ziwunikidwe kenako malo oyenera osungiramo zinthu azindikirike kuti apewe dzimbiri komanso kuti aphimbe bwino.

Gawo 2: Kupanga mabotolo osapangidwa / osamalizidwa
Kawirikawiri kuponyera ndi kupangira zinthu zimagwiritsidwa ntchito pagawoli. Njira zina zingagwiritsidwenso ntchito:
1. Kuyeretsa
2. Kujambula Zithunzi (Mwamsanga)

Gawo 3: CNC makina
Gawolo likapangidwa kudzera mu njira yopangira/kuponyera, limapangidwa ndi makinawo malinga ndi miyeso yofunikira nthawi zambiri ndi CNC.
Ntchito zomwe zikutsatiridwa apa ndi izi: kuloza, kuyang'ana, kugwetsa.

Gawo 4: Kuchiza Kutentha
Kukonza kutentha kumachitika pambuyo pokonza kuti zomangira zikhale zolimba. Ntchito zolimbitsa ndi kutenthetsa zimatsatiridwa.
Choyamba, kuuma kumachitika mwakuti bolt imatenthedwa kufika kutentha kwa 850-900°C kenako kuzimitsidwa mu malo ozizira.
Kachiwiri, boti imatenthedwanso kuti boti yolimba kwambiri isakhale yofewa kwambiri, kuti boti ikhalebe yolimba. Kutenthetsanso kumachitika kuti botiyo isakhale yolimba kwambiri monga momwe idachitikira panthawi yolimbitsira.

Gawo 5: Kumaliza Pamwamba
Chotsatira ndi njira yomaliza pamwamba. Nthawi zambiri, njira yopera imachitika kuti pamwamba pakhale posalala malinga ndi momwe pamwamba pake pamapangidwira.

Gawo 6: Kuzungulira Ulusi
Pambuyo pomaliza ndondomekoyi, kukulunga ulusi kumachitika ndi ma die awiri. Limodzi limakhala losasunthika ndipo lina ndi die yosuntha yomwe imakanikiza mabolt ndikupanga ulusi.

Gawo 7: Kupaka

Pambuyo pozungulira ulusi, maboliti ndi zomangira zomangira zimakutidwa kuti zisachite dzimbiri ndi dzimbiri. Chitsanzo chabwino cha chophimba cha boliti ndi chophimba cha geomet m'maboliti chomwe chidzayesedwa ku SST (Salt Spray Test) kutengera kuchuluka kwa maola monga momwe zafotokozedwera.

Makina otchedwa FISCHERSCOPE amagwiritsidwa ntchito kudziwa makulidwe a chophimba pamodzi ndi zida zina zoyezera makulidwe monga mita yoyezera makulidwe a chophimba.

Gawo 8: Kuyang'anira mawonekedwe, kuyenerera ndi ntchito:

Pambuyo pa zonse zomwe zachitika, pamapeto pake gawolo lipita kukayang'aniridwa. Liyenera kukwaniritsidwa
1. Mayeso a Torque, SST
2. Kugwirizana ndi mtedza
3. Mphamvu ya Impact (Kuyesa kwa Impact charpy)
4. Mayeso a mphamvu yokoka (% kutalika kwa bolt)
5. Kuuma kwa bolt
6.Kukhuthala kwa zokutira
Kuyang'anira miyeso etc.

Chitsanzo chomwe tingapereke
