Chifukwa chiyani chogwirira ntchito chimasokonekera mukatenthedwa ndi zida zowumitsira?

The zida zolimbitsa imatenthetsa workpiece mwachangu kwambiri, ndipo Kutentha ndi yunifolomu, yomwe imangokumana ndi kugwiritsidwa ntchito kowonjezeka kwa zida zosiyanasiyana zakuzimitsira. Ndi kudzera mukutentha mwachangu komanso kuziziritsa mwachangu kwazitsulo kuti mupeze kokha kolimba ngati martensite. Titha kungogwiritsa ntchito njira zingapo kuwongolera kuchuluka kwa mapangidwe, koma vuto la mapangidwe a workpiece silingathetsedwe kwathunthu.

1. Kulipira ndi kukonza

Chida cholimbitsira chotenthetsera chikatenthedwa, chogwirira ntchito chimapanga zolakwika zosiyanasiyana. Chonde tengani njira zofananira kuti muteteze.

Mukamapanga crankshafts, kutuluka kwa fiber kumachitika chifukwa cha kusintha kwamachitidwe. Mbali zina zimakonzedwa pang’ono, koma zina zimakonzedwa kwambiri.

2. Kuzizira kosagwirizana

Ngati mafuta ozimitsa amatha kuyenda mosasunthika pamagawo onse ogwira ntchito, ndiye kuti cholembera chilichonse ndi magawo osiyanasiyana a workpiece amatha kuzirala mofananamo, yomwe ndi njira yofunika kwambiri yopewera kusinthaku.

Zida zazing’ono zomwe zimakhwimitsidwa ndikulimbitsidwa ndi zida zowumitsira, ngati chowotcha lawi ndi shaft sizili pamtunda womwewo ndipo mtunda kuchokera pamalo opopera madzi sizikugwirizana, kusinthako kudzawonjezeka pakutha. Kuphatikiza pakukonzanso kosazolowereka kosazolowereka, mutha kupitilira Onjezani kuti muchepetse kupindika.

Zitatu, kuthamanga

Magawo a shaft amatambasula mukatenthedwa ndi zida zolimbitsa. Ngati kutanuka sikuli bwino, kapena ngakhale kulimba kwake kuli bwino, ziwalozo zimapindika ndikupunduka chifukwa chothinidwa kwambiri kapena shaft yayitali kwambiri.

Chachinayi, kapangidwe kake ndi kosayenera

Mumapangidwe apangidwe, ndikofunikira kupewa mawonekedwe osakanikirana ndi magawo osagwirizana, komanso kusiyana kwa masitepe kukhala ochepa momwe zingathere, komanso kusintha kosalala ndi ma circular ozungulira pamakona.

Zisanu, kupsinjika

Ndi njira zotsatirazi, titha kuchepetsa kwambiri kusinthaku kwa cholembedwacho pambuyo pakuumitsa. Zomwe zachitika zikuwonetsa kuti ngati kutentha kwakukulu kumawonjezeredwa m’zigawo za shaft mutatha kupanga, kupsinjika kwamakina ndi kuwongolera kupondereza kusanathe kumatha.
