1. Nkọwa nke ịgha oyi
Ntu oyi, nke a makwaara dị ka ịgha olu oyi, bụ usoro nrụpụta yana usoro nhazi.N'ụzọ bụ isi dị ka stamping usoro, oyi forging usoro mejupụtara ihe, ebu na akụrụngwa.Ma ihe na stamping nhazi bụ tumadi efere, na ihe na oyi forging nhazi bụ tumadi diski waya.Japan (JIS) a na-akpọ oyi forging (oyi forging), China (GB) a na-akpọ oyi aga, n'èzí ịghasa factory dị ka ịkpọ isi.
2. Isi echiche nke oyi forging
Ntu oyi na-ezo aka na igwe recrystallization okpomọkụ n'okpuru olu dị iche iche na-akpụ.Dị ka ozizi nke metalology si kwuo, okpomọkụ recrystallisation nke dị iche iche metal ihe dị iche iche.T = (0.3 ~ 0.5) T agbaze.Okpomọkụ recrystallization kacha nta nke igwe ferrous na nke na-abụghị igwe.Ọbụlagodi na ọnọdụ okpomọkụ dị n'ime ụlọ ma ọ bụ ọnọdụ okpomọkụ, a naghị akpọ usoro nhazi nke lead na tin ka ọ na-akpụ akpụ oyi, kama ọ na-akpụ akpụ ọkụ.Ma ígwè, ọla kọpa, aluminum na-akpụ nhazi na ụlọ okpomọkụ nwere ike na-akpọ oyi forging.
Na metallics, nke forging ihe kpụ ọkụ n'ọnụ n'elu recrystallization okpomọkụ (banyere 700 ℃ maka ígwè) na-akpọ na-ekpo ọkụ forging.
N'ihi na ígwè forgings, recrystallization okpomọkụ dị n'okpuru na elu karịa ka nkịtị okpomọkụ forging ka a na-akpọ na-ekpo ọkụ forging.
Uru nke isi oyi (extrusion)
Na fastener akpụ, oyi isiokwu (extrusion) technology bụ isi nhazi teknụzụ.Isiokwu oyi (extrusion) bụ nke ụdị nhazi nrụgide ígwè.Na mmepụta, na okpomọkụ nkịtị, a na-etinye ígwè ahụ ike n'èzí, nke mere na ígwè ahụ na-emepụta ihe na-emepụta ihe, a na-akpọkarị usoro a isi oyi.
The akpụ nke ọ bụla fastener bụghị nanị a deformation ụzọ oyi isiokwu, ọ nwere ike na-aghọta na usoro nke oyi isiokwu, na mgbakwunye na iwe iwe, ma na-esonyere n'ihu na azụ extrusion, mejupụtara extrusion, punching ịcha, mpịakọta na ndị ọzọ. ụzọ deformation.Ya mere, aha oyi na-atụ na mmepụta bụ naanị aha omenala, a ga-akpọkwa ya isiokwu oyi (squeeze) nke ọma.
Isi oyi (extrusion) nwere ọtụtụ uru, ọ dabara maka mmepụta oke nke fasteners.Isi uru ya gụnyere akụkụ ndị a:
Ọnụ ọgụgụ dị elu nke nchara, isi oyi (mpanye) bụ usoro nke obere, enweghị ịkpụ, dị ka mkpanaka nhazi, cylinder isi hex socket skru, hex head bolt machining method, ojiji nke ígwè na 25% ~ 35%, na naanị na usoro oyi na-atụ (squeeze), na ọnụ ọgụgụ ojiji ya nwere ike ịdị elu dị ka 85% ~ 95%, bụ naanị isi, ọdụ na isi hex bee ụfọdụ usoro oriri.
