Momwe mungasinthire nthawi yolimbikitsira yapakatikati yamakina owotcherera pafupipafupi?

Nthawi pakati pa chisanadze kukanikiza nthawi ndi pressurization nthawi wapakatikati pafupipafupi malo kuwotcherera makina ndi wofanana ndi nthawi kuchokera yamphamvu kanthu kwa mphamvu yoyamba pa. Ngati kusinthana koyambira kumasulidwa panthawi yotsegulira, kusokonezeka kwa kuwotcherera kudzabwerera ndipo pulogalamu yowotcherera siidzachitika.

Nthawi ikafika nthawi yokakamiza, ngakhale chosinthira choyambira chikatulutsidwa, makina owotcherera amangomaliza ntchito yowotcherera. Moyenerera kusintha preloading nthawi yomweyo kusokoneza ndi kupewa workpiece kuwonongeka ngati workpiece si bwino anaika pa ndondomeko kuwotcherera.

Mu kuwotcherera kwa mfundo zambiri, nthawi yowonjezerera nthawi yoyamba yotsegulira nthawi ya pressurization imagwiritsidwa ntchito, ndipo nthawi yokhayo ya pressurization imagwiritsidwa ntchito pakuwotcherera kwachiwiri. Powotchera ma point ambiri, chosinthira choyambira chiyenera kukhalabe poyambira. Kutalika kwa prepressing ndi pressurization kuyenera kusinthidwa molingana ndi kukula kwa mpweya komanso kuthamanga kwa silinda. Mfundo ndi kuonetsetsa kuti workpiece ndi mphamvu pambuyo wothinikizidwa.
