Kupanga Tanthauzo Ndi Concept

1. Tanthauzo la kuzizira kozizira

Cold forging, yomwe imadziwikanso kuti cold volume forging, ndi njira yopangira komanso njira yopangira. Momwemonso njira yosindikizira, njira yoziziritsira yozizira imapangidwa ndi zinthu, zisankho ndi zida. Koma zakuthupi pakukonza masitampu nthawi zambiri zimakhala mbale, ndipo zinthu zomwe zimagwiritsidwa ntchito pozizira kwambiri zimakhala ndi waya wa disk. Japan (JIS) wotchedwa ozizira forging (ozizira forging), China (GB) wotchedwa ozizira mutu, kunja wononga fakitale ngati kuitana mutu.

2. Basic mfundo za ozizira forging

Cold forging amatanthauza kutentha kwachitsulo recrystallization pansipa zosiyanasiyana voliyumu kupanga. Malinga ndi chiphunzitso cha zitsulo, kutentha recrystallization wa zipangizo zosiyanasiyana zitsulo ndi osiyana. T = (0.3 ~ 0.5) T sungunuka. Kutentha kochepa kwa recrystallization kwazitsulo zachitsulo komanso zopanda chitsulo. Ngakhale pa kutentha kwa firiji kapena kutentha kwabwinobwino, kupangika kwa mtovu ndi malata sikutchedwa kufota kozizira, koma kufota kotentha. Koma chitsulo, mkuwa, zotayidwa kupanga processing firiji akhoza kutchedwa ozizira forging.

Muzitsulo, kupangira zinthu kumatenthedwa pamwamba pa kutentha kwa recrystallization (pafupifupi 700 ℃ kwa chitsulo) kumatchedwa kutentha kotentha.

Pakuti forgings zitsulo, recrystallization kutentha m'munsimu ndi apamwamba kuposa wamba kutentha forging amatchedwa ofunda forging.

Ubwino wa mutu ozizira (extrusion)

Pakupanga cholumikizira, ukadaulo wozizira (extrusion) ndiye ukadaulo waukulu wokonza. Kuzizira mutu (extrusion) ndi gulu la zitsulo kuthamanga processing. Popanga, pa kutentha kwabwino, chitsulo chimagwiritsidwa ntchito kunja kwa mphamvu, kotero kuti chitsulo mu nkhungu yokonzedweratu kupanga, njirayi imatchedwa mutu wozizira.

Kupanga chomangira aliyense si njira mapindikidwe a mutu ozizira, akhoza anazindikira mu ndondomeko ozizira mutu, kuwonjezera kukhumudwitsa mapindikidwe, komanso limodzi ndi kutsogolo ndi kumbuyo extrusion, gulu extrusion, kukhomerera kudula, kugudubuza ndi zina. njira deformation. Choncho, dzina la mutu wozizira popanga ndi dzina lachizoloŵezi, ndipo liyenera kutchedwa mutu wozizira (finyani) molondola.

Mutu wozizira (extrusion) uli ndi zabwino zambiri, ndizoyenera kupanga zomangira zambiri. Ubwino wake waukulu umaphatikizapo zinthu izi:

Kugwiritsa ntchito kwambiri chitsulo, mutu wozizira (kufinya) ndi njira yochepetsera, osadula, monga ndodo yopangira, zomangira zomangira hex socket, hex head bolt Machining njira, kugwiritsa ntchito chitsulo mu 25% ~ 35%, ndi kokha ndi njira yozizira yamutu (kufinya), ndipo kugwiritsa ntchito kwake kumatha kufika 85% ~ 95%, ndi mutu, mchira ndi mutu wa hex wodula zina mwazomwe zimadya.

Kuchulukirachulukira: poyerekeza ndi kudula wamba, mutu wozizira (extrusion) kupanga mphamvu ndi kangapo kuposa.

Good makina katundu: ozizira mutu (extrusion) processing wa zigawo, chifukwa zitsulo CHIKWANGWANI si kudula, kotero mphamvu ndi bwino kuposa kudula.

Zoyenera kupanga zokha: zomangira (kuphatikizanso zigawo zina zooneka mwapadera) zoyenera kupanga mutu wozizira (extrusion) ndizozigawo zofananira, zoyenera kupanga makina othamanga kwambiri, ndiyenso njira yayikulu yopangira misa.

Mwachidule, njira yozizira yamutu (extruding) ndi mtundu wa njira yosinthira yokhala ndi phindu lalikulu lazachuma, lomwe limagwiritsidwa ntchito kwambiri m'makampani ogulitsa. Komanso ndi patsogolo processing njira chimagwiritsidwa ntchito kunyumba ndi kunja ndi chitukuko chachikulu.
