Kuzizira kozizirandi mtundu waukadaulo wopanga pulasitiki wolondola, wokhala ndi zabwino zosayerekezeka, monga zida zabwino zamakina, zokolola zambiri komanso kugwiritsa ntchito zinthu zambiri, makamaka zoyenera kupanga misa, ndipo zitha kugwiritsidwa ntchito ngati njira yopangira zinthu zomaliza, kuzizira kozizira muzamlengalenga ndi zoyendera. Makampani opanga zida zamakina ndi mafakitale ena amagwiritsa ntchito kwambiri. Pakadali pano, kutukuka kwachangu kwamakampani amagalimoto, makampani oyendetsa njinga zamoto ndi zida zamakina kumathandizira kuti pakhale chitukuko chaukadaulo waukadaulo wazopanga zozizira.Cold forging ndondomekoku China mwina sangayambe mochedwa, koma liwiro chitukuko ali ndi kusiyana kwakukulu ndi mayiko otukuka, mpaka pano, kupanga China cha ozizira forging pa galimoto masekeli zosakwana 20 kg, lofanana ndi theka la mayiko otukuka, ali ndi kuthekera kwakukulu kwa chitukuko. , kulimbikitsa chitukuko chakuzizira koziziraukadaulo ndi kugwiritsa ntchito ndi ntchito yofunika kwambiri mdziko lathu pano.
Maonekedwe a forgings ozizira ayamba kukhala ovuta kwambiri, kuyambira pachiyambi cha shaft, zomangira, zomangira, mtedza ndi ma conduits, ndi zina zotero, mpaka mawonekedwe a forgings ovuta. Zomwe zimachitika pa shaft ya spline ndi: ndodo yotulutsa -- kusokoneza mutu wapakati -- extrusion spline; Njira yayikulu yopangira manja a spline ndi: chikho chakumbuyo cha extrusion - - pansi mu mphete - - manja otulutsa. Pakali pano, ukadaulo wozizira wotulutsa zida za cylindrical wagwiritsidwanso ntchito bwino popanga. Kuphatikiza pa zitsulo zachitsulo, aloyi yamkuwa, aloyi ya magnesium ndi aluminium alloy alloy amagwiritsidwa ntchito kwambiri pozizira.

Kupitirizabe ndondomeko zatsopano
Cold precision forging ndi (pafupi) kupanga maukonde. Zigawo zomwe zimapangidwa ndi njirayi zimakhala ndi mphamvu zambiri, zolondola kwambiri komanso zapamwamba. Pakalipano, kuchuluka kwazitsulo zozizira zomwe zimagwiritsidwa ntchito ndi galimoto wamba kunja kwa dziko lapansi ndi 40 ~ 45kg, pakati pazigawo zonse za dzino ndizoposa 10kg. Kulemera kumodzi kwa zida zoziziritsa kuzizira kumatha kufika kupitirira 1kg, ndipo kulondola kwadzino kumatha kufika pamilingo 7.
Kupitirizabe zamakono zamakono zalimbikitsa chitukuko cha teknoloji yozizira extrusion. Kuyambira zaka za m'ma 1980, akatswiri odziwa kupanga molondola kunyumba ndi kunja adayamba kugwiritsa ntchito chiphunzitso cha shunt forging mpaka kuzizira kwa magiya a spur ndi helical. Mfundo yayikulu ya shunt forging ndikukhazikitsa shunt cavity kapena njira yazinthu zomwe zimapanga gawo lopanda kanthu kapena kufa. Popanga, gawo lina lazinthu limathamangira ku shunt cavity kapena njira ndikudzaza patsekeke. Pogwiritsa ntchito ukadaulo wa shunt forging, makina opangira zida zolondola kwambiri komanso osadulira afika mwachangu pamafakitale. Pazigawo zotulutsa zokhala ndi chiyerekezo cham'mimba mwake 5, monga pini ya pistoni, kuzizira kotulutsa nthawi imodzi kumatha kutheka potengera chipika cha axial chotsalira kudzera pa axial shunt kwambiri, ndipo kukhazikika kwa nkhonya ndikwabwino. Pakupanga zida za flat spur, mawonekedwe ozizira opangira ma forging amathanso kuzindikirika pogwiritsa ntchito midadada yotsalira yotsalira.
Block forging ndi pafupi kufa kudzera mmodzi kapena awiri nkhonya njira imodzi kapena zosiyana extrusion zitsulo kupanga mu nthawi imodzi, kupeza pafupi woyera mawonekedwe abwino forging popanda kung'anima m'mphepete. Zigawo zina zamagalimoto zolondola, monga mapulaneti ndi theka la shaft gear, manja a nyenyezi, kunyamula mtanda, ndi zina zotero, ngati njira yodulira ikugwiritsidwa ntchito, osati kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito ndizochepa kwambiri (zosakwana 40% pafupifupi), komanso. mtengo wa maola a munthu, mtengo wokwera wopangira. Ukadaulo wotsekera wotsekedwa umatengedwa kuti upangitse ma forgings oyera kunja, omwe amachotsa njira zambiri zodulira ndikuchepetsa mtengo kwambiri.
Kukula kwa njira yozizira yopangira zida makamaka kukulitsa zinthu zamtengo wapatali kuti muchepetse mtengo wopangira. Panthawi imodzimodziyo, imalowanso nthawi zonse kapena kulowetsa minda ya kudula, ufa zitsulo, kuponyera, kutentha kwamoto, kupanga mapepala achitsulo, etc., ndipo ikhoza kuphatikizidwa ndi njirazi kuti apange njira zophatikizana. Tekinoloje yotentha yopangira pulasitiki yotentha ndi njira yatsopano yopangira zitsulo yomwe imaphatikiza ukadaulo wotentha komanso wozizira. Zimatengera mwayi wokwanira pazabwino zopangira zotentha komanso zozizira motsatana. Chitsulo chotentha chimakhala ndi pulasitiki yabwino komanso kupanikizika kochepa, kotero njira yayikulu yosinthira imatsirizidwa ndi kupangira kutentha. Kulondola kwa kuzizira kozizira ndikwambiri, kotero miyeso yofunika kwambiri ya zigawozo imapangidwa ndi kuzizira kozizira. Tekinoloje yotentha yopangira pulasitiki yopangira pulasitiki idawoneka m'ma 1980, ndipo yakhala ikugwiritsidwa ntchito kwambiri kuyambira m'ma 1990. Magawo opangidwa ndiukadaulowu apeza zotsatira zabwino pakuwongolera kulondola komanso kuchepetsa mtengo.
