Iyo abantu benshi bumvise 'ibice bitunganijwe neza', bashushanya imashini nziza ya CNC yikubita hasi, igacira ibice byuzuye. Nibyo urumuri rwo kwamamaza. Ukuri, igice cyingenzi mubyukuri, nicyo kibera mumipaka - ibyemezo byafashwe mbere yigikoresho cya mbere gikora kuri stock, no gukemura ibibazo bibaho mugihe, byanze bikunze, ikintu kitajya kuri gahunda. Ntabwo ari ukwihanganirana gusa; ni ukumva uburyo ubwo bworoherane bubaho kwisi, mubibazo, mubushyuhe, mubiterane. Amaduka menshi cyane amanikwa kubushobozi bwimashini kumpapuro, akibagirwa ko ibikoresho, ibikoresho, ingamba zo gukoresha inzira, ndetse na coolant, aribwo bukemurampaka nyabwo.
Urufatiro: Itangirana na Casting
Ntushobora gukora imashini neza muburyo bubi. Aha niho imishinga myinshi, cyane cyane iyigoye, ijya kuruhande hakiri kare. Twabonye icapiro ryibintu bya turbine cyangwa umubiri wa valve, hanyuma guhita twibanda gusimbuka kwihanganira bore kwihanganira no hejuru birangira. Ariko niba gukina kwambere bifite kugabanuka imbere, uburebure bwurukuta rudahuye, cyangwa ahantu hakomeye, urwana urugamba rwo gutsindwa kuva mugitangira. Gutunganya bihinduka ibikorwa byo gukiza, ntabwo aribikorwa byuzuye.
Iyi niyo mpamvu inzira yacu kuri Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ni mu buryo busubira inyuma kuri bamwe. Hamwe nimyaka irenga 30 mugukina, tureba igice cyose. Kumubiri wumuvuduko mwinshi wa valve muri duplex idafite ibyuma, ikiganiro gitangirana nigishushanyo mbonera cyibikorwa byo gushora imari. Nigute dushobora kuyobora igice mugikonoshwa kugirango tumenye neza icyerekezo kandi tugabanye ububobere mubice bikomeye byo gufunga? Icyo cyemezo, cyafashwe ibyumweru mbere yo gutunganywa, gifite ingaruka nini mugushikira igice-cyanyuma, gihamye cyane kuruta icyahinduwe kumunota wanyuma kuri CNC.
Ndibuka akazi kumashanyarazi ya marine mumashanyarazi ya nikel. Umukiriya yaje iwacu nyuma yandi mangazini arwana no kumena ibikoresho kandi ntashobora gufata ibipimo byerekana. Ikibazo ntabwo cyari gahunda yo gutunganya; yari ingano yintete muri casting. Inzira yumwimerere yashizeho uburyo butemewe, bworoshye. Twongeye gushushanya sisitemu yo kwinjirira mugikonoshwa cyibikorwa kugirango dutezimbere ingano imwe, nziza. Mu buryo butunguranye, gutunganya byari byarahanuwe, ibikoresho byarakomeje, kandi impirimbanyi zingana byari byiza muri spec. Uwiteka gutunganya neza ibice yaratsinze kuko casting yabigenewe.
Ibikoresho ntabwo ari uguhitamo gusa kumurongo wamanutse
Gukorana nudusimba twihariye nka cobalt-ishingiye cyangwa Inconel ikurikirana ntabwo ari uguhindura gusa ibintu birwanya kwambara. Imyitwarire yibikoresho itegeka byose. Nibiganiro nicyuma. Ibyuma bidafite ingese, kurugero, bifuza gukora-gukomera. Winjiye ukoresheje urumuri ruciriritse, ibiryo bitinze, kandi urashobora gutobora hejuru, bigatuma inzira ikurikira irushaho gukomera no kwangiza igikoresho. Ukeneye icyizere cyo gufata ubukana buhagije kugirango ugere munsi yurwego rukomereye akazi, bisaba guhuza bikomeye hamwe na mashini ifite torque.
Noneho hari ubushyuhe. Gukora aya mavuta bitanga ubushyuhe bukabije, bwaho. Ubwo bushyuhe bugana he? Ahanini mubikoresho, niyo mpamvu guhitamo gukonjesha no gusaba ari ngombwa. Ariko nanone ijya mubice. Kubice bikikijwe n'inkuta ya cobalt alloy aerospace bracket, uko kwagura ubushyuhe nukuri. Urashobora kuyikora kugirango igere neza kuri 25 ° C, ariko ubushyuhe buva mumashini bwaraguye. Iyo ikonje inyuma mucyumba cyubugenzuzi, ntibishobora kwihanganira. Ugomba kwishyura ibyo, haba muburyo bukonje cyangwa muri gahunda yawe ya CAM. Nibyiyumvo utera imbere mugihe, ukareba uko chipi zigoramye nibara ryazo.
Ibi twabyize inzira igoye hakiri kare hamwe nicyicaro cya Stellite. Twese twabashizeho kugeza kumpera yo hasi yihanganira, dufata inzira nziza, nziza. CMM yaberetse byose bidashyizwe munsi gato nyuma yuburinganire bwumuriro. Byabaye ngombwa ko usiba ubufindo. Noneho, kubipimo byingenzi kuri ibyo bikoresho, twubaka muri offset yumuriro cyangwa, icyiza kurushaho, koresha murwego rwo kugenzura nyuma yo kugenzura gukonje. Yongera igihe, ariko ni itandukaniro hagati yigice na a igice cyuzuye.
CNC ni Umufatanyabikorwa, Ntabwo ari Umupfumu
Kureshya kwa 5-axis yo gutunganya ikigo birakomeye. Igitekerezo cy'uko ushobora guhuza ibice bigoye hamwe na mashini buri kintu cyose ni tekiniki. Ariko ibikorwa biratandukanye. Igihe cyose uhengamye umutwe cyangwa ukazenguruka ameza, uba uhinduye vector yo gukata imbaraga, imikorere ya coolant, hamwe nuburemere bwimikorere. Kubyubakishijwe ibyuma biremereye, ibyo ntacyo bitwaye. Kuburyo bworoshye, butarangiye bwa 17-4 PH idafite umwanda, birashobora kuganisha kubiganiro cyangwa gutandukana.
Rimwe na rimwe, uburyo buke busobanutse neza. Turashobora guhitamo gukora igikorwa cya kabiri kumurongo wa 3-axis hamwe nibikoresho byabugenewe kugirango bishyirireho ibyambu, kuko iyo mikorere itanga ituze ntagereranywa kubikorwa byihariye. Intego nigice cyanyuma ubunyangamugayo, kuterekana ubushobozi bwimashini. Ubunararibonye bwitsinda mugucira urubanza ibi - mugihe cyo gukoresha 5-axis icyarimwe, igihe cyo kwerekana, igihe cyo gukoresha icyiciro cya kabiri-nigiciro kitagaragara. Ntushobora kugura iyo software.
Nari nsubiramo gahunda yimikorere ejobundi kuri manifold. Injeniyeri ukiri muto yari yateguye gahunda nziza, ikora imwe-igizwe na 5-axis toolpath. Byasaga neza neza na simulation. Ariko namusabye kubihindura. Imwe mu mpapuro zirangiza zaba zarasize igikoresho gikurura ibikoresho muburyo bugororotse, bujyanye nicyo cyiciro cyihariye cyicyuma, cyateza imbere ubuso bubi mumaso ikomeye. Twabigabanyijemo ibice bibiri. Byatwaye igihe kirekire, ariko kurangiza byari byiza. Imashini ni igikoresho; inzira yubumenyi nubukorikori.
Ubugenzuzi: Inkuru Ibyatanzwe
Gutsindira ingingo ya mbere igenzura ni ikintu kimwe. Kumva impamvu watsinze nibintu byose. Twishingikirije cyane kuri CMM yacu hamwe na profilometero yubuso bwa profilometero, ariko ntabwo ari kashe ya pass / gutsindwa gusa. Dushakisha imiterere. Niba umurambararo wa bore kumurongo wibyuma bya pompe yamashanyarazi bigenda byerekeza kuruhande rwo hejuru rwo kwihanganira, ariko mubisanzwe, icyo ni ikimenyetso. Nibikoresho byo kwambara? Guhindura ubushyuhe buke? Cyangwa nicyitegererezo mugukina ubwacyo - birashoboka ko bigoramye, bigoretse bike muburyo bwo gukina ubu dushobora guhanura no kwishyura muri CAM?
Aya makuru yo gusubiza amakuru niho hubatswe ubudahwema nyabwo. Ifunga icyuho kiri hagati yububiko bwa casting na centre yimashini. Twasangiye ubwoko bwa raporo hamwe nitsinda ryacu bwite ryabakinnyi, biganisha kuri tweaks mugikorwa cyo gutekesha ibishishwa byagabanije kugabanya ibisigisigi kandi bigatuma imashini ihagarara neza. Iyo ugenzuye inzira zombi, uba ufite uburambe-oya, inshingano-yo gukoresha amakuru kuva murimwe kugirango utezimbere undi.
Kurugero, amakuru aturuka kumashanyarazi adasanzwe akenshi atwereka imashini yibikoresho byimashini bihoraho. Iyo intel isubira mubikoresho byacu. Ni urwego rwo kwishyira hamwe birashoboka gusa mugihe gutunganya bitagaragara nka serivisi yihariye, ariko nkicyiciro kimwe mubuzima bwigice. Iyi ni filozofiya twubatse kuri QSY mu myaka mirongo itatu, kandi irambuye muburyo bwacu tsingtaocnc.com. Intego ntabwo ari ugukora igice cyo gucapa uyu munsi, ahubwo ni ukumva inzira cyane kuburyo dushobora kuyikora neza, kandi byateganijwe ejo.
Umutego mwiza uhagije
Ikibazo gikomeye muri gutunganya neza ibice ntabwo buri gihe ari tekiniki; ni ubucuruzi. Umuvuduko wo kugabanya ikiguzi kuri buri gice ni kinini. Kandi burigihe harigihe igice ari cyiza gihagije - kinyura QC, gihuye (ahanini), umukiriya ntashobora no kubibona. Ariko uwo ni umutego. Mubisabwa nkabakoresha ibinyomoro bishingiye kuri cobalt dukunze gukorana - tekereza sisitemu ya lisansi cyangwa ibikoresho byinganda byambaye imyenda-byiza birananirana. Birananira buhoro, bihenze, kandi biteje akaga.
Gusubiza inyuma kuri ibi bisaba ijwi ryumvikana. Bisobanura rimwe na rimwe kubwira umukiriya ko kwihanganira ibyifuzo byabo kubintu bidakomeye ari ukubatwara bitarenze 20%, cyangwa ko amanota atandukanye yabaha imikorere myiza kubyo basabye. Nukuba umufatanyabikorwa ukora, ntabwo ari umucuruzi gusa. Aha niho imyaka 30 yimiterere ifite akamaro. Twabonye uburyo ibice binanirwa mu murima, kandi ibyo biratangaza uburyo dushimangira ko byakozwe.
Ubwanyuma, gutunganya neza ni imyitozo yo kwizerana. Umukiriya atwizeye gusobanukirwa n'ibisabwa bitavuzwe - ubuzima bw'umunaniro, ukwezi k'ubushyuhe, imitwaro y'iteraniro - bitari ku gishushanyo ariko byanditswe mubisabwa. Twabonye icyo cyizere twerekana akazi kacu, dusobanura impamvu inyuma yo guhitamo inzira, no kugira amateka yo gukina, ibyemezo bifatika, hamwe nuburyo bwuzuye bwo kubishyigikira. Nicyo gicuruzwa nyacyo. Igice cyakorewe ni ibimenyetso bifatika.
