Kusiyana kwa Cold Forging ndi Hot Forging

Cold forging and otentha forging ndi njira ziwiri zofunika zomwe zimafala pakupanga zitsulo.Iwo ali ndi kusiyana kwakukulu mu pulasitiki zinthu, kutentha, microstructure, ndi ntchito zosiyanasiyana.M'nkhaniyi, tikambirana mwatsatanetsatane makhalidwe a njira ziwirizi, komanso kugwiritsa ntchito makina ozizira ndi otentha pakupanga kwenikweni.

Kusiyana pakati pa kuzizira kozizira ndi kufota kotentha

Cold forging amatanthauzakukonza ndondomekoikuchitika firiji, ndi kutentha kwa workpiece zitsulo ndi wotsika kuposa kutentha recrystallization.Chifukwa cha kusauka kwa pulasitiki kwa zinthu pa kutentha kochepa, kuzizira kozizira nthawi zambiri kumafuna mphamvu yaikulu kuti iwononge pulasitiki.Choncho, kuzizira kozizira ndi koyenera kwa zipangizo za alloy ndi mphamvu zapamwamba.Hot forging ndi kupanga ndondomeko ikuchitika pansi pa zinthu mkulu-kutentha, ndi kutentha kwa workpiece zitsulo ndi apamwamba kuposa kutentha recrystallization.Pa kutentha kwambiri, zitsulo zimakhala ndi pulasitiki yabwino, kotero kuti kutentha kwamoto kumafunika kugwiritsa ntchito mphamvu zochepa, zomwe zimakhala zoyenera pamitundu yosiyanasiyana yazitsulo.

Kusiyana kwa kutentha pakati pa kuzizira kozizira ndi kutentha kotentha kumakhudza kwambiri microstructure ya zinthu.Pakuzizira kozizira, njere zachitsulo sizimakonda kukonzanso, kotero morphology ya mbewu zoyambirira nthawi zambiri imasungidwa pambuyo pozizira kozizira.Pakuwotcha kotentha, njere zachitsulo zimakhala zosavuta kukonzanso pa kutentha kwakukulu, kotero kuti mawonekedwe a yunifolomu ndi abwino kwambiri ambewu nthawi zambiri amapezeka pambuyo popanga kutentha.Chifukwa chake, kupangira kotentha kumatha kupititsa patsogolo kulimba komanso pulasitiki yazinthu.

Kuphatikiza apo, kuzizira kozizira komanso kufota kotentha kumakhala ndi mitundu yosiyanasiyana yogwiritsira ntchito.Cold forging imagwiritsidwa ntchito kwambiri popanga zida za aloyi zokhala ndi mphamvu zambiri komanso mapulasitiki otsika, monga chitsulo champhamvu kwambiri.Chifukwa kuzizira kozizira kumafuna kugwiritsa ntchito mphamvu zazikulu, nthawi zambiri amagwiritsidwa ntchito popanga tinthu tating'onoting'ono komanso tosavuta.Kutentha kotentha kumakhala koyenera pazinthu zambiri zachitsulo.Itha kupanga zida zogwirira ntchito zokhala ndi mawonekedwe ovuta ndipo zimatha kukonza kulimba komanso kukhazikika kwazinthu.Amagwiritsidwa ntchito kwambiri popanga zida zazikulu zamafakitale monga zida zamagalimoto, zida zam'mlengalenga, ndi makina opanga uinjiniya.

Makina opukutira ozizira ozizira ndi makina otentha opangira

A makina ozizira ozizirandi chida chapadera chozizira chopangira njira, mbali yake yayikulu ndikuti imatha kuchita zitsulo zopangira zitsulo firiji.Makina oziziritsa ozizira nthawi zambiri amakhala ndi makina opangira ma hydraulic ozizira ndi makina ozizira ozizira.Makina opangira ma hydraulic ozizira amayendetsa njira yopangira ma hydraulic system, yomwe ili ndi mphamvu yayikulu yopangira komanso kusinthasintha ndipo imatha kugwiritsidwa ntchito popanga ma workpiece amitundu yosiyanasiyana.Makina ozizira opangira makina amazindikira njira yopangira kudzera pamakina.Poyerekeza ndi makina opangira ma hydraulic ozizira, mphamvu yake yopangira ndi yaying'ono, koma ili ndi zabwino pazogwiritsa ntchito zina.
Makina opangira otentha ndi chida chapadera chopangira zitsulo zotentha ndipo amatha kupanga zitsulo pansi pa kutentha kwambiri.Nthawi zambiri amatengera ma hydraulic kapena mechanical transmission.Ndipo mitundu yosiyanasiyana ya makina amasankhidwa malinga ndi mphamvu yopangira mphamvu ndi zofunikira za ndondomeko.Theotentha forging pressamatenthetsa workpiece zitsulo pamwamba pa kutentha recrystallization kuti afike plasticity wabwino ndiyeno imagwiritsa ntchito mphamvu yoyenera kumaliza ndondomeko forging.

Pakupanga kwenikweni, makina onse ozizira ozizira komanso makina otentha otentha amatenga gawo lofunikira.Makina oziziritsa ozizira ndi oyenera zida za aloyi zomwe zimakhala ndi pulasitiki yotsika komanso zofunikira zamphamvu.Nthawi zambiri amagwiritsidwa ntchito popanga zing'onozing'ono zogwirira ntchito, monga ma bolts, mtedza, etc. Makina otentha otentha ndi oyenera zipangizo zachitsulo zomwe zimakhala ndi zofunikira kwambiri pa pulasitiki yakuthupi ndipo zimafunika kuwongolera kulimba ndi pulasitiki.Itha kupanga zida zazikulu komanso zowoneka bwino, monga ma crankshaft amagalimoto ndi zida za injini ya aero.

Kufotokozera mwachidule, kuzizira kozizira ndi kupangira kutentha ndi njira ziwiri zomwe zimagwiritsidwa ntchito popanga zitsulo.Ndipo ali ndi kusiyana kwakukulu kwa kutentha, pulasitiki yakuthupi, microstructure, ndi ntchito zosiyanasiyana.Cold forging ndi yoyenera kwa zida za aloyi zokhala ndi mphamvu zambiri komanso pulasitiki yotsika, pomwe kupangira kotentha ndikoyenera zitsulo zamitundu yosiyanasiyana, makamaka zomwe zimafunikira kuwongolera kulimba ndi pulasitiki.Makina oziziritsa ozizira ndi makina opangira otentha ndi zida zapadera zomwe zimagwiritsidwa ntchito kuzindikira njira ziwirizi.Amagwira ntchito yofunika kwambiri pakupanga zitsulo, kupereka zigawo zazitsulo zapamwamba zamafakitale osiyanasiyana.

Zhengxi ndi wodziwika bwinowopanga makina osindikizira ku China, kupereka makina opangira ozizira ozizira komanso makina otentha otentha.Ngati muli ndi zosowa, chonde titumizireni nthawi yomweyo.Akatswiri athu amakupatsirani mayankho abwino kwambiri a hydraulic press.
