Njira zoyambira zopangira kwaulere zimaphatikizapo kukhumudwitsa, kukulitsa, kukhomerera, kupindika, kupindika, kusamuka, kudula, ndi kupanga.
Free forging elongation
Elongation, yomwe imadziwikanso kuti kukulitsa, ndi njira yopangira yomwe imachepetsa gawo lozungulira la billet ndikuwonjezera kutalika kwake. Elongation imagwiritsidwa ntchito popanga ndodo ndi ma shaft. Pali njira ziwiri zazikuluzikulu zotalikitsira: 1. kukweza pachochonde chophwathalala. 2. Wonjezerani pa ndodo yapakati. Pakupanga, ndodo yapakati imalowetsedwa mu nkhonya yopanda kanthu kenaka imakulitsidwa ngati yopanda kanthu. Pojambula, nthawi zambiri samachita nthawi imodzi. Chosowacho chimayamba kukokedwa kukhala mawonekedwe a hexagonal, kupangidwa mpaka kutalika kofunikira, kenako kuzunguliridwa ndi kuzungulira, ndipo ndodo yapakati imachotsedwa. Kuti muthe kuchotsa ndodo yapakati, gawo logwira ntchito la ndodo yapakati liyenera kukhala ndi malo otsetsereka a 1:100. Njira yotalikirayi imatha kukulitsa kutalika kwa billet, kuchepetsa makulidwe a khoma, ndikusunga mkati mwake. Nthawi zambiri amagwiritsidwa ntchito popanga malaya amtundu wautali.
Zopanda malire komanso zopanda malire
Kukwiyitsa ndi njira yopangira yomwe imachepetsa kutalika kwa chopanda kanthu ndikuwonjezera gawo la magawo. Njira yokwiyitsa imagwiritsidwa ntchito makamaka popanga ma giya osasowekapo ndi zopangira keke zozungulira. Njira yokhumudwitsa imatha kusintha bwino mawonekedwe a billet ndikuchepetsa anisotropy yama makina. Kubwerezabwereza kukhumudwitsa ndi kukulitsa kumatha kusintha kapangidwe kake komanso kugawa kwa carbides muzitsulo zachitsulo cha aloyi. Pali mitundu itatu yayikulu yokhumudwitsa: 1. Kukhumudwitsa kwathunthu. Kusokoneza kwathunthu ndi njira yoyika chopanda kanthu pamwamba pa anvil, ndipo pansi pa chiwombankhanga chapamwamba, chopandacho chimakhala ndi mapindikidwe a pulasitiki ndi kuchepa kwa msinkhu komanso kuwonjezeka kwa gawo lozungulira. 2. Kuthetsa kukhumudwitsa. Mukatenthetsa chopanda kanthu, mbali imodzi imayikidwa mu mbale yotayira kapena nkhungu ya tayala kuti muchepetse kusinthika kwa pulasitiki kwa gawo ili, ndiyeno mbali ina ya chopandacho imamenyedwa kuti ipangitse kukhumudwitsa. Njira yokhumudwitsa yogwiritsira ntchito mbale zomwe zikusowa nthawi zambiri zimagwiritsidwa ntchito popanga magulu ang'onoang'ono; Njira yosokoneza nkhungu ya matayala imagwiritsidwa ntchito popanga misa. Pansi pamikhalidwe yopanga chidutswa chimodzi, mbali zomwe zimafunikira kukhumudwa zimatha kutenthedwa kwanuko, kapena zigawo zomwe siziyenera kukhumudwa zimatha kuzimitsidwa m'madzi mutatha kutentha kwathunthu, kenako kukhumudwa kumatha kuchitika. 3. Kukhumudwa pakati. Njirayi imagwiritsidwa ntchito popanga ma forging okhala ndi gawo lalikulu lapakati komanso magawo ang'onoang'ono omaliza, monga ma giya opanda kanthu ndi mabwana mbali zonse. Musanasokoneze chosowekacho, nsonga zonse ziwiri za chosowekacho ziyenera kuzulidwa kaye, ndiyeno chopandacho chizimenyedwera molunjika pakati pa mbale ziwiri zotulukamo kuti zisokoneze gawo lapakati la chosowekacho. Pofuna kupewa kupindika kwa billet panthawi yachisokonezo, chiŵerengero cha kutalika kwa billet h mpaka m'mimba mwake dh/d ndi ≤ 2.5.
Kukhomerera kwaulere
Kukhomerera ndi njira yokhomera yomwe imaphatikizapo kuboola kapena kubowola popanda kanthu. Pali njira ziwiri zazikuluzikulu zokhomerera: 1. Njira yokhomerera mbali ziwiri. Mukamagwiritsa ntchito nkhonya kuti mukhomenye zopanda kanthu mpaka kuya kwa 2/3-3/4, chotsani nkhonyayo, tembenuzani chopanda kanthu, ndiyeno gwirizanitsani nkhonyayo ndi malo kuchokera mbali ina kuti mubowole. 2. Njira yokhomerera m'mbali imodzi. Njira imodzi yokhomerera mbali imodzi ingagwiritsidwe ntchito pa billets ndi makulidwe ang'onoang'ono. Pokhomerera, chopanda kanthu chimayikidwa pa mphete yochirikiza, ndipo mapeto aakulu a nkhonya ya tapered pang'ono imagwirizana ndi malo okhomerera. Chosowekacho chimamenyedweramo mpaka dzenjelo litalowa.
