1.Iriburiro
Amavuta ya aluminiyumu afite imbaraga ziciriritse agaragaza uburyo bwiza bwo gutunganya, kuzimya ibyiyumvo, gukomera kwingaruka, no kurwanya ruswa. Bakoreshwa cyane mubikorwa bitandukanye, nka electronics na marine, mugukora imiyoboro, inkoni, imyirondoro, ninsinga. Kugeza ubu, harakenewe kwiyongera kuri 6082 ya aluminiyumu. Kugirango duhuze ibyifuzo byamasoko nibisabwa nabakoresha, twakoze ubushakashatsi kubikorwa bitandukanye byo gushyushya ibicuruzwa hamwe nuburyo bwa nyuma bwo gutunganya ubushyuhe bwa 6082-T6. Intego yacu yari ukumenya uburyo bwo kuvura ubushyuhe bwujuje ibyangombwa bisabwa kugirango utubari.
2.Ibikoresho byubushakashatsi hamwe nuburyo bwo gutunganya umusaruro
2.1 Ibikoresho by'igerageza
Gutera ingero zingana na F162 × 500 byakozwe hakoreshejwe uburyo bwa kimwe cya kabiri gikomeza kandi bikorerwa imiti imwe. Ubwiza bwa metallurgical of ingots bwujuje ubuziranenge bwikigo imbere. Ibigize imiti ya 6082 bivangwa bigaragara mu mbonerahamwe ya 1.
2.2 Uburyo bwo gutunganya umusaruro
Ubushakashatsi bwakorewe 6082 bwari bufite ibisobanuro bya Ф14mm. Igikoresho cyo gukuramo cyari gifite umurambararo wa Ф170mm ufite igishushanyo mbonera cya 4 cyo gukuramo na coefficient ya 18.5. Inzira yihariye yarimo gushyushya ingot, gusohora, kuzimya, kurambura kugorora no gutoranya, kugorora uruziga, gukata bwa nyuma, gusaza ibihimbano, kugenzura ubuziranenge, no gutanga.
3. Intego zubushakashatsi
Icyari kigamijwe muri ubu bushakashatsi kwari ukumenya ibipimo byo gutunganya ubushyuhe bwo gukuramo ubushyuhe hamwe n’ibipimo bya nyuma byo gutunganya ubushyuhe bigira ingaruka ku mikorere y’utubari 6082-T6, amaherezo tugera ku bisabwa bisanzwe. Ukurikije ibipimo ngenderwaho, imiterere ya mashini ndende ya 6082 ivanze igomba kuba yujuje ibisobanuro biri mu mbonerahamwe ya 2.
4.Ubushakashatsi
4.1 Iperereza ryo Kuvura Ubushyuhe
Iperereza ryokuvura ubushyuhe bwibanze cyane cyane ku ngaruka ziterwa no guta ubushyuhe bwa ingot hamwe nubushyuhe bwa kontineri yubushyuhe. Guhitamo ibipimo byihariye birambuye mu mbonerahamwe ya 3.
4.2 Igisubizo gikomeye hamwe nubusaza bwo kuvura ubushyuhe
Igishushanyo mbonera cya orthogonal cyakoreshejwe mugukemura gukomeye no gusaza uburyo bwo kuvura ubushyuhe. Urwego rwatoranijwe rutangwa mu mbonerahamwe ya 4, hamwe nimbonerahamwe yerekana imiterere ya IJ9 (34).
5.Ibisubizo n'isesengura
5.1 Ibisubizo Byubushakashatsi Bwakorewe Ubushakashatsi hamwe nisesengura
Ibyavuye mu bushakashatsi bwo kuvura ubushyuhe bwerekanwe mu mbonerahamwe ya 5 n’ishusho 1. Ingero icyenda zafashwe kuri buri tsinda, kandi hagaragajwe impuzandengo y’imikorere y’ubukanishi. Hashingiwe ku isesengura ry’ibyuma n’ibigize imiti, hashyizweho uburyo bwo kuvura ubushyuhe: kuzimya 520 ° C mu minota 40 no gusaza kuri 165 ° C mu masaha 12. Kuva ku mbonerahamwe ya 5 n’ishusho ya 1, birashobora kugaragara ko uko ubushyuhe bwo guta ingot hamwe nubushyuhe bwa kontineri bwiyongereye, imbaraga zingutu nimbaraga zitanga umusaruro byiyongera buhoro buhoro. Ibisubizo byiza byabonetse kubushyuhe bwa 450-500 ° C hamwe nubushyuhe bwa kontineri ya 450 ° C, bujuje ibyangombwa bisanzwe. Ibi byatewe n'ingaruka z'imirimo ikonje ikomera ku bushyuhe buke bwo guterwa, bigatuma imvune zimbibi zimbibi kandi byongera kwangirika gukomeye hagati ya A1 na Mn mugihe cyo gushyushya mbere yo kuzimya, biganisha ku kongera gukora. Mugihe ubushyuhe bwo gukuramo bwiyongereye, imbaraga zanyuma Rm yibicuruzwa byateye imbere cyane. Iyo ubushyuhe bwa kontineri yubushuhe bwegereye cyangwa burenze ubushyuhe bwa ingot, ihindagurika ridahwanye ryaragabanutse, bigabanya ubujyakuzimu bwimpeta nini kandi byongera umusaruro Rm. Rero, ibipimo bifatika byo kuvura ubushyuhe ni: ubushyuhe bwo gukuramo ingot ya 450-500 ° C hamwe nubushyuhe bwa kontineri ya 430-450 ° C.
5.2 Igisubizo gikomeye hamwe nubusaza Orthogonal Ibisubizo byubushakashatsi hamwe nisesengura
Imbonerahamwe 6 irerekana ko urwego rwiza ari A3B1C2D3, hamwe no kuzimya kuri 520 ° C, ubushyuhe bwo gusaza bwubukorikori buri hagati ya 165-170 ° C, no gusaza kumasaha 12, bikavamo imbaraga nyinshi na plastike yutubari. Inzira yo kuzimya ikora igisubizo gikomeye. Ubushyuhe bwo hasi bwo kuzimya, kwibumbira hamwe kwumuti urenze urugero bigabanuka, bigira ingaruka kumbaraga. Ubushyuhe bwo kuzimya hafi 520 ° C bwongera cyane ingaruka zo kuzimya-guterwa no gukomera gukomeye. Intera iri hagati yo kuzimya no gusaza kwubukorikori, ni ukuvuga kubika ubushyuhe bwicyumba, bigira ingaruka cyane kumiterere. Ibi bigaragara cyane kubiti bitarambuye nyuma yo kuzimya. Iyo intera iri hagati yo kuzimya no gusaza irenze isaha 1, imbaraga, cyane cyane umusaruro, zigabanuka cyane.
5.3 Isesengura rya Microstructure Microstructure
Isesengura ryinshi hamwe n’isesengura ryakozwe ku tubari 6082-T6 ku bushyuhe bukomeye bwa 520 ° C na 530 ° C. Amafoto yo hejuru cyane yerekanaga imvura igwa hamwe nibice byinshi byimvura igabanijwe neza. Isesengura ryumucyo ukoresheje ibikoresho bya Axiovert200 ryerekanye itandukaniro ritandukanye kumafoto yimiterere yintete. Agace ko hagati kagaragaje ibinyampeke bito kandi bimwe, mugihe impande zerekanaga bimwe byongeye kugarurwa hamwe nintete ndende. Ibi biterwa no gukura kwa nuclei ya kirisiti ku bushyuhe bwo hejuru, ikora inshinge nini zimeze nk'imvura.
6.Isuzuma ryimyitozo yumusaruro
Mu musaruro nyirizina, imibare yimikorere yakozwe mubice 20 byutubari na 20 byimyirondoro. Ibisubizo byerekanwe mu mbonerahamwe ya 7 n'iya 8. Mu musaruro nyirizina, gahunda yo gusohora yakorewe ku bushyuhe bigatuma T6 ingero za leta, kandi imikorere ya mashini yujuje indangagaciro.
7.Umwanzuro
(1) Ibipimo byo kuvura ubushyuhe bukabije: Ubushyuhe bwo gukuramo ubushyuhe bwa 450-500 ° C; ubushyuhe bwa kontineri yubushyuhe bwa 430-450 ° C.
(2) Ibipimo byanyuma byo kuvura ubushyuhe: Ubushyuhe bwiza bwo gukemura bwa 520-530 ° C; ubushyuhe bwo gusaza kuri 165 ± 5 ° C, gusaza amasaha 12; intera iri hagati yo kuzimya no gusaza ntigomba kurenza isaha 1.
. ubushyuhe bukomeye bwa 510-520 ° C; gahunda yo gusaza ya 155-170 ° C mu masaha 12; nta karimbi kihariye ku ntera iri hagati yo kuzimya no gusaza. Ibi birashobora kwinjizwa mumabwiriza yimikorere.
