A halin yanzu, wasu masana'antun crankshaft a kasar Sin sun gabatar da tsarin sarrafa tasirin iska daga kasashen Jamus, Italia, Spain da sauran kasashe. Koyaya, manufacturersan masana'antun ne kawai suka gabatar da dukkanin layin aikin.

2. Kirkirar fasahar karfe karafa

A cikin 'yan shekarun nan, an gabatar da wasu kayan aikin kirkire na zamani a kasar Sin, amma saboda karancin adadin, hade da fasahar kera kere-kere da sauran kayan aiki, wasu kayan aikin na zamani ba su taka rawar da ta kamata ba. Gabaɗaya, akwai tsofaffin kayan aikin ƙirƙira waɗanda suke buƙatar gyara da sabunta su. A lokaci guda, fasaha da kayan aiki na baya suna riƙe da matsayi mai mahimmanci, kuma ana amfani da ingantaccen fasaha amma har yanzu bai bazu ba.

3. Fasahar sarrafa inji

A halin yanzu, yawancin layukan samar da crankshaft na cikin gida an haɗa su da kayan aikin masarufi na yau da kullun da kayan aikin masarufi na musamman, kuma ingancin samarwa da sarrafa kansa ba su da yawa. Kayan aiki masu amfani da kayan aiki galibi suna amfani da lathe na kayan aiki da yawa don juya babban mujallar crankshaft da wuya, kuma ingancin kwanciyar hankali na aikin ba shi da kyau, kuma yana da sauƙi don samar da babban damuwa na ciki, kuma yana da wahala a cimma abin da ya dace inji izni Janar gamawa yana amfani da injunan niƙaƙƙen mashin kamar MQ8260 don ƙara niƙa - ƙarewa-ƙare - nika mai kyau - goge, yawanci ta aikin hannu, kuma ingancin sarrafawa ba shi da karko.

4. Heat jiyya da kuma surface ƙarfafa magani magani

Maballin fasaha don maganin zafin jiki na crankshaft shine karfafa ƙarfin farfajiya. Ductile baƙin ƙarfe crankshafts an daidaita su gabaɗaya kuma an shirya su don shirya ƙasa. Magungunan ƙarfafa samaniya gabaɗaya suna amfani da tauraruwar haɓaka ko nitriding. Ana tafiya da ƙarƙƙƙen ƙarfe na ƙarfe. Kayan da aka shigo da su sun hada da AEG mai cire crankshaft da kuma EMA quenching machine.
