Iyo abantu benshi bumvise 'ibicuruzwa bikozwe na powder metallurgie', bahita batekereza kuri ibyo bikoresho bito, bigoye cyane cyangwa byifashisha amavuta. Ibyo ntabwo ari bibi, ariko ni nkaho gusobanura imodoka ukoresheje ibyuma byayo. Ukuri gushizwe cyane mubuzima bwa buri munsi bwinganda kuruta uko. Hariho imyumvire itari yo, cyane cyane kubakozi bakorana cyane nicyuma gishongeshejwe, nko mu ruganda rwacu, ko ibice bya PM aribindi bihendutse, bikora neza. Mumaze imyaka ibarirwa muri za mirongo muri Qingdao Qiangsenyuan Technology Co., Ltd. Binyuze mu bufatanye butaziguye n'abashinzwe gutanga PM no kugerageza gusimbuza ibice bimwe na bimwe nasobanukiwe neza aho ifu ya metallurgie imurika - kandi aho itagaragara rwose.
Imiterere yubucuruzi: Aho PM ibereye
Kuri QSY, isi yacu ni ibyuma byamazi - gusuka, gukomera, gutunganya. Noneho, mugihe umukiriya winteko ya hydraulic yateranije gutsimbarara ku gukoresha PM yakozwe na PM aho gukoresha verisiyo ya mashini ya CNC ivuye mububiko, nagize amakenga. Igishushanyo cyahamagaye imiyoboro yimbere yimbere yari inzozi mbi kumashini. Isoko rya PM yatanze igice-hafi-net-shusho. Ubucucike nubuso bwo kurangiza byari impungenge zahise. Cyakoze, ariko igipimo cyumuvuduko cyagombaga guteshwa agaciro gato ugereranije nuwakozwe. Uku gucuruza-bigoye kugabanyirizwa gato mumitungo yubukanishi-ni imibare ya buri munsi muriki gice.
Aha niho hafatirwa icyemezo nyacyo. Ntabwo ari inzira 'nziza' mu cyuho. Kubyibushye cyane bya turbine mubyuma bishingiye kuri nikel, gushora imari nigihome cyacu. Ariko kuri kamera nini cyane, ifite kamera nini mumashanyarazi avanze, aho gukoresha ibikoresho biva mumashini byaba munsi ya 40%, ifu ya metallurgie itangira kuririmba indirimbo yayo ya siren. Impaka zishingiye ku bukungu n’ibintu zirakabije, mugihe igishushanyo mbonera cyiza cyo guhuza no gucumura guhera.
Ndibuka kugerageza kunanirwa gukoresha PM ihuza inkoni muri moteri ya prototype. Amakuru yumunaniro yasaga neza kumpapuro, ariko twabuze nuance yimiterere ya anisotropique. Igice cyananiranye mu ndege ikanda munsi yikizunguruka, uburyo bwa PM bwananiwe uburyo igice cyahimbwe cyangwa cyashizweho kitagaragaza muburyo bumwe. Byari isomo rikomeye ko udashobora gufata igishushanyo cyigice cyakozwe hanyuma ukohereza mububiko bwa PM. Igishushanyo kigomba kuvuga ururimi rwibikorwa.
Ibiganiro Byibikoresho: Amavuta hamwe ninyungu za PM
Ibi biganisha ku bikoresho. Akazi kacu kuri QSY hamwe n'amavuta adasanzwe nka cobalt-ishingiye kuri nikel akenshi ni kubidukikije bikabije-ubushyuhe bwinshi, ruswa. Powder metallurgie ifite umukino udasanzwe hano gukina ntibishobora guhura byoroshye: ibyuma bya matrix na Inzego. Nabonye ibice bya PM aho uduce twa ceramic dukwirakwizwa kimwe muri materique ya aluminiyumu kugirango irwanye kwambara, ikintu kidashoboka kugerwaho nta gutandukanya gukabije muri casting.
Kubikoresho byihuta byibyuma, PM numwami. Imiterere ya karbide nziza, ukura muri atomize no guhuza ifu bivamo igikoresho gisya neza kandi cyambara neza kurenza uko bisanzwe gisanzwe. Dutanga ibikoresho byakozwe na PM kubikoresho byacu bwite bya CNC. Itandukaniro muburyo buhoraho hagati yitsinda riragaragara.
Nyamara, hari aho bigarukira. Kubintu binini, byubaka muburyo bukomeye mubyuma bidafite ibyuma bikoreshwa mumazi, turacyashingira kuri casting. Ubunyangamugayo bukabije bwigice cyashizwe neza, imiterere yacyo ya isotropique, hamwe nubushobozi bwo gutanga ibice biremereye cyane biracyabiha impande zose. Ibice bya PM, birenze ubunini, birwana nuburinganire. Nimbogamizi yumubiri yibikorwa byingutu.
Imbyino ya Dimensional: Ubworoherane nibikorwa bya kabiri
Ingingo nini yo gutongana, cyangwa kuruta kutumva, ni kwihanganira ibipimo. 'Hafi-net-shusho' isezerano rya ifu ya metallurgie ni ukuri, ariko 'hafi' nijambo rikoreshwa. Kubiranga perpendicular yerekeza kanda, urashobora kwihanganira ibintu bitangaje, rimwe na rimwe mubihumbi bibiri bya santimetero. Ariko mu cyerekezo cyihuta, urimo guhangana na comptabilite yo kugaruka no kugabanuka kugabanuka, byongeraho guhinduka.
Hafi ya buri gice gikomeye cya PM twakemuye gikorerwa ibikorwa bya kabiri. Aho niho sosiyete nkiyacu, hamwe nimbaraga Imashini ya CNC ubuhanga, akenshi biza mubishusho. Ibikoresho byacumuye birashobora gukenera gusya cyangwa gusya kuri bore, cyangwa ibice byubatswe bishobora gukenera isura ikomeye yakozwe kugirango yizere neza. Gukorana birasobanutse: PM irema geometrie igoye neza, kandi gutunganya neza byongeraho gukoraho kunegura. Nukuboko kwintoki hagati yimikorere, ntabwo ari umusimbura.
Ndibuka ko nagenzuye icyiciro cya PM flanges aho umuzenguruko wa bolt wari muto nyuma ya sinteri. Impamvu? Ubucucike butari bumwe buturutse hagati-bwuzuza urupfu. Umucuruzi wa PM yagombaga kongeramo intambwe yo kubikosora. Ubu bwoko bwibikorwa ntibigaragara kurupapuro rwamakuru ariko nukuri kwaburi munsi mubikorwa.
Gutwara Ibitaboneka: Ubukungu nyabwo
Umuntu wese avuga kubijyanye no kuzigama kwa PM, nukuri - ntabwo uhindura 60% yibikoresho byawe. Ariko inkuru yukuri yibiciro iri mubikoresho nubunini. Ibishushanyo byo guhuza ifu bihenze, biragoye, kandi birakomeye. Birumvikana ko umusaruro ukoreshwa mubice 50.000, ntabwo ari 500.Ibi bihabanye rwose na logique yacu yo guta umucanga, aho igiti gihenze kandi cyihuse.
Hariho kandi ikiguzi cyihishe cya powder ubwacyo. Ifu yo mu rwego rwohejuru, ibanziriza ifu yicyuma ntabwo ihendutse. Kubisanzwe ibyuma-umuringa-karubone bivanze, birarushanwa. Ariko iyo winjiye muri izo feri ya nikel cyangwa ibikoresho byuma, ibikoresho fatizo kubiro birashobora kuguha guhagarara. Urimo kwishyura inzira ya atomisation hamwe nubunini bugabanijwe kugabanywa. Gutsindishirizwa bigomba kuva mubikorwa no kurandura intambwe yo gutunganya intambwe.
Twakoze isesengura ryibiciro kumuryango wibice bito bya lever. Mubice 5000, CNC itunganya ibicuruzwa byabigenewe byari bihendutse. Ku bice 50.000, PM yarihendutse 30%. Kuri 500.000, icyuho cyagutse kugera kuri 50%. Ariko ibi byafashwe gusa niba igishushanyo mbonera cyahujwe mukinyamakuru kimwe. Ongeraho urwego rwa kabiri ibiranga ukoresheje ibikorwa bitandukanye byishe margin. Ingingo yubukungu-niyo ngingo ni intego igenda, yunvikana cyane kubishushanyo mbonera.
Urebye Hirya no hino: Gukina na PM Icyerekezo
Kuva ku cyicaro cyanjye mu ruganda rukora imashini, kuzamura PM byabaye inyigisho. Byaduhatiye gukara kubyerekeye agaciro kacu bwite. Kubice bifite umwobo w'imbere-nkuwimuka ufite icyuma gitwikiriye - gushora imari biracyatsindwa. PM ntashobora kubikora. Kubice bisaba ubucucike bukabije nubuzima bwumunaniro, nka crankshaft ya moteri ikora cyane, guhimba biracyategeka, nubwo PM yibeshya irimo kwinjira.
Ariko kuri iyo mpamvu nini yo hagati yuburyo, kwambara, hamwe na magnetiki - tekereza Muyunguruzi, clutch hubs, pole ibice bya moteri - ifu ya metallurgie ni amahitamo meza atavuguruzwa. Ninzira ikuze, ihanitse. Ubwihindurize bwa tekinike nko guterwa inshinge (MIM) byarushijeho guhindura umurongo, bituma ibice bito, bigoye cyane bidasanzwe bitaba PM gakondo cyangwa micro-casting byashoboraga gukemura mubukungu.
Mu kurangiza, ni ukugira igikoresho cyiza kumurimo. Kuri Qingdao Qiangsenyuan Technology Co., Ltd., imbaraga zacu nuguhindura ibyuma byamazi mubice byuzuye, byizewe. Ifu ya metallurgie ni isanzure isanganywe aho ibyuma bikomeye byegeranijwe mubice byingenzi. Ba injeniyeri bazi ubwenge nzi ko badasezerana inzira imwe. Basobanukiwe ururimi rwabo bose - gukina, gutunganya, guhimba, na ifu ya metallurgie- hanyuma uhitemo imvugo ivuga neza ibicuruzwa byabo. Igikorwa nyacyo kibaho mubisobanuro.
