Fasaha masana'antu Crankshaft:

1. Fasahar simintin gyare-gyare na ƙwanƙwasa ƙarfe na ductile

A. Narkewa

Samun babban zafin jiki, ƙarancin sulfur, ƙarfe mai tsabta mai tsabta shine mabuɗin don samar da ƙarfe mai inganci mai inganci.Kayan aikin samar da gida sun fi dogara ne akan cupola, kuma narkakken ƙarfe ba a riga an ƙazantar da shi ba;na biyu shine ƙarfen alade mai tsabta da ƙarancin ingancin coke.A halin yanzu, an yi amfani da hanyar narkar da narke-tsalle na waje sau biyu, wanda ke amfani da kofi don narkar da narkakkar baƙin ƙarfe, ya lalata shi a wajen tanderun, sannan ya yi zafi yana daidaita abubuwan da ke cikin tanderun shigar da shi.A halin yanzu, an gudanar da gano narkakkar ƙarfe na cikin gida gabaɗaya ta amfani da na'urar sikirin karantawa kai tsaye.

B. Samfura

Tsarin gyare-gyaren tasirin iska a bayyane ya fi aikin nau'in yashi na yumbu, kuma ana iya samun simintin ƙulla madaidaicin madaidaicin crankshaft.Yashi mold samar da tsari yana da halaye na babu rebound nakasawa, wanda yake da muhimmanci musamman ga Multi-juya crankshaft.A halin yanzu, wasu masana'antun crankshaft a cikin kasar Sin sun gabatar da hanyoyin sarrafa tasirin iska daga Jamus, Italiya, Spain da sauran ƙasashe.Duk da haka, kawai 'yan masana'antun sun gabatar da dukkanin layin samarwa.

2. Ƙirƙirar fasahar ƙirƙira na ƙarfe crankshaft

A cikin 'yan shekarun nan, an samar da wasu na'urori na zamani na jabu a kasar Sin, amma saboda karancin adadi, hade da fasahohin kera na'ura da sauran kayayyakin aiki, wasu na'urorin zamani ba su taka rawar da ya kamata ba.Gabaɗaya, akwai tsoffin kayan aikin ƙirƙira da yawa waɗanda ke buƙatar gyara da sabunta su.A lokaci guda, fasahar baya da kayan aiki har yanzu sun mamaye matsayi mafi girma, kuma an yi amfani da fasahar ci gaba amma har yanzu ba a yadu sosai ba.

3. Fasahar sarrafa injina

A halin yanzu, yawancin layukan samar da crankshaft na cikin gida sun ƙunshi kayan aikin injin na yau da kullun da na'urori na musamman na injuna, kuma ingancin samarwa da sarrafa kansa ba su da ƙarancin ƙarfi.Kayan aiki na roughing galibi suna amfani da lathe-kayan kayan aiki da yawa don kunna babban jarida na crankshaft da wuyansa, kuma ingancin kwanciyar hankali na tsari ba shi da kyau, kuma yana da sauƙi don haifar da babban damuwa na ciki, kuma yana da wahala a cimma daidaito mai ma'ana.injialawus.Gabaɗaya gamawa yana amfani da injunan niƙa crankshaft kamar MQ8260 don m niƙa - Semi-karewa - niƙa mai kyau - gogewa, yawanci ta hanyar aikin hannu, kuma ingancin sarrafawa ba shi da tabbas.

4. Heat magani da kuma surface ƙarfafa jiyya fasahar

Makullin fasaha don maganin zafi na crankshaft shine jiyya mai ƙarfafawa.Ductile baƙin ƙarfe crankshafts gaba ɗaya an daidaita su kuma an shirya su don shirye-shiryen saman.Jiyya na ƙarfafawa gabaɗaya suna amfani da hardening induction ko nitriding.Ƙarfe na crankshafts na ƙirƙira ana tattara su kuma an zagaye.Kayan aikin da aka shigo da su sun haɗa da na'urar kashe wuta ta atomatik AEG da injin kashe wuta na EMA.

Wuxi Lead Precision Machinery Co., Ltdyana ba abokan ciniki na kowane girma duka cikakkesabis na ƙirƙira ƙarfe na al'adatare da matakai na musamman.
