Ọkpụkpụ crankshaft bụ "ọkpụkpụ azụ" nke injin, na-ekpebi ike, ogologo ndụ, na ntụkwasị obi nke isi ike. Iji nagide ọnọdụ arụ ọrụ siri ike, anyị na-etinye njikwa siri ike n'elu ihe yana usoro nrụpụta niile site na mmalite - hụ na ejiri DNA dị elu wuo crankshaft forging ọ bụla.
1. Nhọrọ ihe onwunwe adịchaghị: Ntọala siri ike sitere na isi mmalite
Anyị ghọtara na ihe bụ ihe ndabere nke arụmọrụ. Ewezuga nchara alloy egosipụtara dị ka 42CrMoA, anyị na-arụsi ọrụ ike na-eji igwe anaghị agbanyụ agbanyụ na ọkụ (microalloyed) steel dị ka 49MnVS3 na 48MnV. Site na nju oyi a na-achịkwa mgbe a na-achịkwa, nchara ndị a na-enweta ihe ndị a chọrọ na-enweghị ike-ike, mgbagha na-enwe ike ọgwụgwọ okpomọkụ nke akara mmụta ọdịnala-na-akwalite arụmọrụ, ịcha ego, na ịhụ nkwụsi ike na nkwụsi ike nke akụkụ.
Standardkpụrụ akụrụngwa anyị dị n'ime karịrị oke ụkpụrụ ụlọ ọrụ, yana oke siri ike na ihe ngosipụta ike ike ndụ dị ka ịdị ọcha, nha ọka, na usoro ihe ejikọtara ọnụ. Ihe niile sitere n'aka ndị na-ebubata atụmatụ atụmatụ agbaziri agbaziri n'okpuru usoro nkwekọrịta teknụzụ abụọ gbakwunyere nyocha ọzọ na-abata, na-ewepụ ihe egwu dị na isi mmalite.
2. Isi Usoro: Nkọwapụta nkenke maka ike na ike
Ọkpụkpụ crankshaft siri ike ga-eji oghere adịgboroja adịgboroja - a naghị emepụta ya ozugbo site na ngwaahịa ụlọ mmanya - iji hụ na ọ na-aga n'ihu ọka ọka na igwe na-arụ ọrụ kacha mma.
Ịmepụta nkenke: Integral die forging na RR / TR dị elu na-ewe iwe maka nnukwu crankshafts na-enweta nhazi netwọk ziri ezi n'otu ọrụ na igwe igwe dị arọ. A na-eji ube mechiri emechi eme ihe n'ọtụtụ ebe n'imepụta olu iji bulie itinye ihe n'ọrụ.
Njikwa okpomoku ziri ezi: kpo oku na-enweghị oxygen na-egbochi imezigharị elu elu, yana njikwa ọgụgụ isi nke mmalite na imecha okpomọkụ n'ime ± 15 Celsius C maka ịdị mma na-agbanwe agbanwe.
Arụmọrụ ahaziri ahazi: Anyị na-etinye post-processing dị iche iche site na ihe - nweta ezigbo microstructure na nchara anaghị emenyụ site na nju oyi a na-achịkwa, na itinye nhazi ọkọlọtọ na imenyụ na-ekpo ọkụ na nchara alloy, na-eji nlezianya tinye ya n'oge niile iji belata ndakpọ.
3. Nleba anya siri ike: ọtụtụ nchekwa, nnyefe na-enweghị nchegbu
Forging ọ bụla ga-agafe usoro nyocha anyị tupu ahapụ ya.
100% Nnwale na-adịghị emebi emebi: Onye ọ bụla crankshaft na-enyocha ultrasonic na ihe ndọta, na-enyocha ntụpọ dị n'ime na n'elu na ntụpọ efu efu iji hụ na njupụta dị n'ime na elu enweghị ntụpọ.
Asambodo ikike: Mmepụta na njikwa mma niile na-agbaso ụkpụrụ ụlọ ọrụ kachasị ọhụrụ, gụnyere CB/T 4313-2013. Maka ụgbọ mmiri crankshafts, anyị na-enye asambodo zuru oke na-ekpuchi obodo iri bụ isi (CCS, DNV, ABS, LR, na ndị ọzọ) - na-akwado ngwaahịa gị n'ụwa niile site na nyocha mbata ruo na nnabata ikpeazụ.
Họrọ anyị, ma họrọ:

Ihe ndị na-egbu egbu na njikwa isi iyi siri ike
Advanced forging usoro na kpọmkwem usoro njikwa
Usoro nyocha zuru oke na asambodo ikike

Anyị na-ebuga ngwọta agbakwunyere-site na crankshafts dị elu ruo ọrụ asambodo zuru oke-na-enye ntọala siri ike maka obi engine siri ike, nke a pụrụ ịdabere na ya.
