Iyo wunvise 'icyuma gitera inshinge zikora', ubwenge bwinshi burahita busimbukira hejuru cyane, ntoya, ibice bigoye. Nibyo, ariko kandi niho imyumvire ya mbere yibeshya iba. Abantu batekereza ko aribwo buryo buhendutse bwo gutunganya ibice ibihumbi. Mubyukuri, agaciro ntabwo kari mubunini gusa; ni muri geometrike bidashoboka rwose cyangwa birabujijwe guhembwa imashini cyangwa guta bisanzwe. Umurinzi w'irembo ntabwo ari imashini, ni ibiryo, inzinguzingo, hamwe n'ubumenyi bwo gucumura. Nabonye imishinga myinshi inanirwa kuko umuntu yashakishije a uruganda rukora inshinge hashingiwe ku gatabo kavuzwe udasobanukiwe imyitwarire yo kugabanuka kubintu cyangwa ibikoresho byifashishwa munsi.
Imbyino Yibanze: Ntabwo ari Gushushanya gusa
Inzira ya MIM ni marato, ntabwo ari kwiruka. Utangirana nibiryo bya granular-ifu yicyuma ihagarikwa muri polymer binder. Kubumba ubwabyo byunvikana niba uzi gushushanya inshinge za plastiki. Ariko icyo ni igice cyoroshye. Umaze gukora 'icyatsi kibisi' ahanini gihuza. Noneho haza kugabanuka, intambwe itinze, ikomeye yo gukuraho iyo binder idateye inenge. Byihuta cyane, kandi igice kirabya cyangwa gisenyutse. Aha niho uburambe bwuwabikoze ataka. Amaduka nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), afite amateka yimbitse mu gushora imari, mubyukuri afite ukuguru hano. Imitekerereze yo gucunga ibintu byubushyuhe no guhindura ibintu muburyo bwo gucumura biregeranye. Amateka yabo maremare muri Igikonoshwa na gushora imari bivuze ko atari abanyamahanga kubintu bigoye, hafi-net-shusho yuburyo bukomeye hamwe no kugenzura gukomeye nyuma yo gucumura.
Gucumura ni intambwe yubumaji. Igice kijya mu itanura, naho ibyuma bisigaye byahujwe hamwe, bikabije. Igice kiragabanuka - birashoboka, urizera. Uku kugabanuka guteganijwe ni grail yera. Uruganda rumaze igihe kinini rwubatse imyirondoro yibikoresho bitandukanye - ibyuma bitagira umwanda, idasanzwe-Kugerageza, ikosa, hamwe na metero nyinshi. Ntabwo ari resept isanzwe ukura mu gitabo. Kurugero, igice gifite uburebure butandukanye bwurukuta bizacumura neza niba umwirondoro witanura utabigenewe. Wiga ko mugusenya ibyiciro, ntabwo usoma impapuro zihariye.
Niyo mpamvu imashini ya CNC nyuma yo gucumura batanga ntabwo ari ugutekereza; akenshi ni ngombwa. Ndetse hamwe nuburyo bwiza bwo kugenzura, ibintu bimwe na bimwe-nkurudodo rufite kwihanganira ultra-gufatana cyangwa guhuza ibitsina - birashobora gukenera isuku rya nyuma. Kugira Imashini ya CNC murugo, nkuko QSY ibikora, ninyungu nini. Yemerera kugenzura ibikorwa. Ntabwo wohereje igice cyacumuye kubandi bacuruzi, bishobora guhura nibibazo byo guhuza. Urashobora gushushanya igice cya MIM, uzi ko ibintu byingenzi bya datum bishobora gutunganywa nyuma yo gucumura kugirango uhamagare +/- 0.05mm. Ihindura imbogamizi imbaraga zo gukora imvange.
Guhitamo Ibikoresho: Aho Amavuta aboneka
Kuvuga ibikoresho muri MIM akenshi bitangirana na 17-4PH bitagira umwanda. Ni ifarashi y'akazi. Ariko umurimo wukuri ushimishije ubaho hamwe na alloys bigoye. Aha niho hapimwa ibicuruzwa bya metallurgical. Nickel ishingiye kuri cobalt cyangwa superalloys yo mu kirere cyangwa gutera imiti bitwara bitandukanye cyane mugihe cyo gucumura. Ibintu byabo bigabanuka biratandukanye, ibyiyumvo byabo kumyuka yumuriro (hydrogen, argon, vacuum) nibyingenzi.
Isosiyete ikora uburambe hamwe cobalt na nikel mubikorwa byabo byo gukina, nkuko ubibona kurubuga rwabo kuri https://www.tsingtaocnc.com, ni ikimenyetso cyubushobozi burenze ibyuma byoroshye. Gukoresha ibyo bikoresho bisaba gufata ifu ikaze (kugenzura ogisijeni), gushyiramo itanura rinini, no gusobanukirwa byimbitse uburyo ibikoresho bya nyuma byubukorikori bigerwaho binyuze mukuzunguruka. Ntabwo ari ubucuruzi bwo ku ruhande; ni umwihariko. Ndibuka umushinga wibikoresho byo kubaga byari bikeneye nikel-chromium. Imikorere ya mbere yo gucumura yatangaga ibice byujuje ibintu ariko bifite ihindagurika. Gukosora ntibyagaragaye - byari uguhindura gato ubushyuhe bwo hejuru bwo gufata umwanya hamwe nigipimo cyo gukonjesha, ikintu cyigiye kubushoramari bwabo bashora hamwe nibisigazwa bisa.
Umutego hano urimo gutekereza ko ababikora bose bashobora gukoresha ibikoresho byose byashyizwe kurutonde. Ikibazo ntabwo Urashobora kubikora? ariko Nyereka igice cy'umusaruro wakoze muri iyi mavuta yihariye, hanyuma turebe ibikoresho bifatika hamwe namakuru yikizamini. Ibikoresho biri ku cyemezo cyo guhuza bigomba gukurikiranira hafi inzira igenzurwa, isubirwamo, ntabwo ari amahirwe.
Igikoresho: Umushoferi ucecetse
Igikoresho cya MIM ni ikindi gikoko. Kubera imiterere yo kugaburira amatungo, ibishushanyo bisanzwe bikozwe mubyuma bikomeye. Igishushanyo cya filozofiya itandukanye nuburyo bwo gutera inshinge. Urimo gushushanya igice kizagabanuka kimwe (nibyiza) kuri 15-20%. Noneho, umwobo wububiko urenze urugero. Igishushanyo mbonera ni ingenzi cyane mu gusohora icyatsi kibisi, cyoroshye.
Ibintu bigoye bizana ibintu byimbere hamwe na undercuts. Mububiko bwa plastike, wakoresha kuruhande-ibikorwa cyangwa guterura. Muri MIM, uragerageza kubyirinda nkicyorezo mubikoresho kuko byongera ikiguzi kandi birashobora kugorana gusohora igice cyoroshye cyicyatsi. Akenshi, igishushanyo mbonera ni uguhindura umwobo hanyuma ugakoresha icyiciro cya kabiri kugirango ureme munsi, cyangwa wemere igishushanyo cyoroshye. Nagiye mu nama yo gusuzuma ibishushanyo aho twamaraga isaha imwe tujya impaka kuri 0.5mm munsi - niba ari igikoresho cyayo, kuyikoresha nyuma, cyangwa kuyikuraho burundu. Uburenganzira uruganda rukora inshinge bizagira ibyo biganiro hakiri kare, bisubize inyuma kubishushanyo bidashoboka atari ukubera ko bidashobora kugerageza, ariko kuberako bazi umusaruro nibiciro biva mubitunaniye kera.
Aha niho hajyaho ibibazo byingirakamaro byubuhanga. Uruganda rufata dosiye ya CAD gusa na cote ni akaga. Imwe isaba guhamagarwa kugirango iganire kubyerekeranye nuburebure bwurukuta, aho amarembo, hamwe nibimenyetso bishobora kurohama ni ukuzana uburambe bwibibanza byabo mubikorwa byawe. Ikiza amezi yumubabaro.
Kwishyira hamwe: Kuva Mububiko kugeza Byarangiye Igice
Ibi birashoboka ko aribyiza bitaganiriweho. MIM ni gake intambwe yanyuma. Hano haribisanzwe, gutitira, kuvura ubushyuhe, kubisahani, cyangwa gutunganya neza. Iyo izi ntambwe zigabanijwe kubatanga ibintu bitandukanye, uba ubuze kuyobora. Kwihanganirana kugereranije. Kuyobora ibihe bya ballon. Amakimbirane meza ahinduka inzozi zo gutunga urutoki.
Igikorwa gihuza MIM nuburyo bwakabiri munsi yinzu imwe ikora akazi gahuza. Fata urugero kurugero rwa QSY: bakora casting (MIM ni mubyara wo gushora imari muri filozofiya), gucumura, hanyuma bakagira Imashini ya CNC ubushobozi ku rubuga. Kubintu bisobanutse neza, bivuze ko igice cyacumuye gishobora kwimurwa muburyo bwimashini ya CNC, gishyizwe hamwe ukoresheje ibimenyetso bya datum byacumuye, bikarangira. Gutanga ibitekerezo birakomeye. Niba icyiciro cyo gucumura gikora kinini, gahunda yo gutunganya irashobora guhinduka gato kugirango yishyure. Uru rwego rwo kugenzura ntirugaragara kubakiriya ariko rugaragarira mubice byiza kandi bike byanze ubufindo.
Nayoboye urunigi rwo gutanga aho igice cya MIM cyakorewe mumujyi umwe, cyoherejwe gutunganyirizwa muwundi, hanyuma nongera koherezwa kubisahani. Ibiciro bya logistique hamwe ningaruka nziza akenshi byahanaguye buri gice cyo kuzigama kwa MIM. Icyitegererezo cyahujwe kigabanya ibyo. Ihindura uwabikoze kuva mubicuruzwa bitunganijwe mubisubizo byumufatanyabikorwa wibikoresho bigoye.
None, Mubyukuri Urashaka Niki?
Guhitamo a uruganda rukora inshinge ntabwo ari ugushaka igiciro gihenze kubice igihumbi. Nijyanye no gushakisha ubujyakuzimu. Ugomba kugenzura ubuhanga bwabo, cyane cyane niba urenze 316L idafite umwanda. Ugomba gusobanukirwa nuburyo bwabo bwo gushushanya ibikoresho nubushake bwabo bwo gufatanya kuri DFM (Igishushanyo mbonera). Byinshi cyane, ugomba gusuzuma igenzura ryurwego rwose rwagaciro - kuva kugaburira kugeza igice cyarangiye, cyagenzuwe.
Imiterere yisosiyete, nkimyaka 30 ya QSY mugukora neza no gutunganya neza, ntabwo ari umurongo wo kwamamaza gusa. Ni porokisi yo gukusanya, ubumenyi bwuzuye mugucunga ibyuma muburyo bwa net-shusho. Ayo mateka yerekana ko basobanukiwe nubushyuhe bwumuriro, imiterere yintete, hamwe nuburinganire buringaniye muburyo iduka rishya, ryeguriwe gusa-MIM-iduka rishobora kuba ryiga binyuze mubigeragezo bibabaza.
Ikizamini cyanyuma gihora mubice. Baza ibyitegererezo bivuye mubikorwa, ntabwo ari prototypes nziza. Shyira munsi ya microscope, ubapime, ugerageze. Amateka yuwabikoze yanditswe muburyo bujyanye n'ubucucike bwabyo hamwe nuburemere bwimpande zabo zanyuma. Nibisubizo nyabyo byubushakashatsi bifite akamaro.
