Mukamva 'kampani yaufa', anthu ambiri nthawi yomweyo amajambula fakitale ikung'ambika, zobowoleza zamkuwa kapena zida zachitsulo. Ndicho chithunzi chapamwamba, ndipo si cholakwika, koma chiri ngati kufotokozera malo odyera amakono monga malo omwe amapereka chakudya. Zowona pamtunda ndizovuta komanso zosangalatsa. Vuto lenileni sikungokanikiza ndi kusakaniza ufa; ndi kuphatikizira luso pachimake mu unyolo wathunthu zothetsera, makamaka pamene mukuchita ndi mkulu ntchito zipangizo. Ndawonapo mashopu ambiri akukakamira m'malingaliro omwe timapanga magawo a PM, kupikisana pamtengo pa kilogalamu, pomwe mtengo weniweni umasamukira kumtunda kukapanga ndi kutsika mpaka kumaliza. Awo ndi malo ovuta kukhalamo.
Zinthuzo Ndi Poyambira Poyambira
Tiyeni tikambirane kaye zida, chifukwa ndipamene kukambirana kumayambira. Timagwira ntchito kwambiri ndi chitsulo, chitsulo, ndi ufa wachitsulo chosapanga dzimbiri, koma masewerawa amasintha ndi ma aloyi apadera. Ganizirani ma superalloys opangidwa ndi nickel kapena cobalt pakugwiritsa ntchito kutentha kwambiri. Nali mutu wothandiza: mawonekedwe oyenda a ufa wonyezimira wa aloyi ndi wosiyana kwambiri ndi kusakaniza kwanu kwachitsulo. Atha kukhala ogwirizana kwambiri, osasunthika, omwe amataya makina odzaza okha omwe amalinganizidwa ndi zinthu wamba. Simungangotaya ufa watsopano mu hopper ndikuyembekezera kuchulukana komweko. Zimafunika kusintha nsapato ya chakudya, nthawi zina ngakhale kugwedezeka kwafupipafupi panthawi yodzaza. Ndikachulukidwe kakang'ono, koma kulakwitsa kumatanthauza kusagwirizana kwa gawo musanagunde ng'anjo ya sinter. Ndikukumbukira pulojekiti ina yomwe tidakhala masiku awiri tikungodzaza gawo latsopano la nickel alloy, kuthamanga ma compact compact ndi kuyeza kachulukidwe gradient. Zinkawoneka ngati kuchedwa, koma kudumpha sitepeyo kukanatsimikizira kulephera kwa gulu pambuyo pake.
Apa ndipamene kukhala ndi maziko ochulukira azinthu ndi mwayi waukulu. Opaleshoni yathu ya makolo, Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., wakhala akuponya ndi makina kwa zaka zambiri. Mbiri yozama imeneyo yokhala ndi zitsulo zosungunuka ngati chitsulo chosungunula ndi ma aloyi apadera amatipatsa malingaliro osiyana pa mbali ya ufa. Sitikungogula ufa kuchokera kwa ogulitsa ndikukanikiza mwachimbulimbuli. Timamvetsetsa zitsulo kuchokera kumtunda wamadzimadzi, zomwe zimatidziwitsa momwe timachitira ndi solid-state sintering. Mwachitsanzo, kumvetsetsa makonda a tsankho a zinthu zina mu melt kumatithandiza kuyembekezera momwe angachitire panthawi ya kufalikira kwamphamvu mu sintering. Ndi chidziwitso cholumikizidwa.
Ndipo pomaliza. Mulungu, kutsiriza ndi kumene ambiri ufa zitsulo mapulojekiti amakhala moyo kapena kufa. Mutha kuyika gawo lapafupi ndi ukonde mokongola, koma ngati likufunika chobowolera cholondola kapena chinthu chovuta kwambiri, mupita ku makina a CNC. Kukonza gawo lopangidwa sintered sikuli ngati kukonza bala yopangidwa. Porosity imatha kuwononga zida, ndipo imatha kukhudza momwe zimameta. Tinaphunzira izi movutikira m’mbuyo kwambiri, n’kumayatsa mphero pazimene zinkaoneka ngati chitsulo chosavuta. Tsopano, ma protocol athu opanga magawo a PM ndi osiyana. Timagwiritsa ntchito zida zosiyanasiyana za geometri, nthawi zina zoziziritsa kuzizira zosiyanasiyana, ndipo nthawi zonse timawerengera mosiyanasiyana liwiro ndi chakudya. Ndi ndondomeko Integrated. Mfundo yakuti QSY ili ndi gawo lake lodzipereka la CNC Machining (tsngtaocnc.com tsatanetsatane wa kuthekera kwawo) sizongochitika mwangozi; ndichofunika. Gawolo silinathe pamene likuchoka mu ng'anjo yotentha. Izo zatha pamene izo zakonzeka kwa kasitomala msonkhano mzere.
The Shell Mold Crossover: Niche Worth Worth Exploring
Izi zitha kuwoneka ngati zosiyana, koma pirirani nane. Malo amodzi omwe sapeza chidwi chokwanira ndi mphambano pakati pawo ufa zitsulo ndi kuponya ndalama, makamaka kuponya nkhungu. Nthawi zambiri amawonedwa ngati njira zopikisana, ndipo mbali zambiri, ali. Koma pali synergy mu prototyping ndi otsika voliyumu, mkulu-zovuta ntchito. Tagwiritsa ntchito PM kupanga zida zopangira zipolopolo. Nthawi zina, kasitomala amafunikira gulu loyesera la zida 50 zovuta, zomwe nthawi zambiri zimakhala ntchito yoponya. Kupanga nkhungu yachitsulo popanga zipolopolo ndizokwera mtengo kwambiri pa voliyumu imeneyo. Tachita bwino pogwiritsa ntchito jekeseni wazitsulo (MIM, msuweni wa PM) kapena zitsulo zolimba kwambiri zopangira mabokosi kapena zoyikamo nkhungu popanga zipolopolo. Kumapeto kwake sikokwanira bwino ngati kuyika kwachitsulo chopangidwa ndi makina, koma kwa ma 50-100 oponyera, kumakhazikika ndikuchepetsa nthawi yotsogolera kuchokera miyezi mpaka masabata.
Ndi chinyengo chapadera, osati yankho wamba. Kutentha kwa njinga kuchokera kutsanulira zitsulo zosungunuka mu chipolopolo chomangidwa pazitsulo zosungunula kumayambitsa kutopa ndi kusweka. Koma kupanga mlatho kapena prototyping, ndizofunika kwambiri. Ndimalingaliro amtundu wotere - kugwiritsa ntchito njira imodzi kuthandiza ina - komwe kumalekanitsa malo ogulitsa ntchito ndi omwe amapereka mayankho. Mutha kupeza maphunziro amilandu panjira yophatikizira pollination mu mbiri yotakata Mtengo wa QSYtsamba la. Imalankhula ndi filosofi yogwira ntchito yomwe ikukhudzana ndi kuthetsa mkangano wopanga, osati kungogulitsa njira imodzi.
Mbali yakutsogolo ndikuwongolera zomwe makasitomala amayembekeza. Mukapereka njira yosakanizidwa yotereyi, muyenera kumveketsa bwino za malire. Inde, titha kukupatsirani magawo omwe angayesedwe m'masabata atatu pogwiritsa ntchito njira iyi, koma chidacho chidzasokoneza pambuyo pa kuzungulira kwa 80, ndipo kuuma kwapamwamba pa gawo lomaliza kudzakhala Ra wa 6.3, osati 3.2. Kodi ndizovomerezeka pagawo lanu lovomerezeka? Kukambitsirana moona mtima, kwapatsogolo kumeneko, kozikidwa pa zoyeserera zakale (kuphatikiza zolephera zomwe tidalonjeza kwambiri za moyo wa zida), kumakulitsa chidaliro kuposa kabuku kalikonse kowoneka bwino.
Pamene Kukwanira Kulibe: Msampha Wolekerera
Tolerances mu ufa zitsulo ndi kukambirana kosalekeza ndi physics. Njira yopangira sintering imaphatikizapo kuchepa, ndipo kucheperako sikumakhala kwangwiro kwa isotropic. Zimatengera gawo la geometry, kachulukidwe kachulukidwe ka makina osindikizira, komanso kutentha kwa ng'anjo. Tikhoza kutengera chitsanzo, koma nthawi zonse zimakhala zosiyana. Pazigawo zambiri zamapangidwe, kulolerana kwa PM ndikwabwino. Koma tikufunsidwa kwambiri kuti tipange zida zomwe zimapikisana ndi zida zamakina pakukhazikika kwazithunzi.
Izi zimakukankhirani muzochitika zachiwiri monga kukula (kukanikizanso gawo losanjidwa mu kufa) kapena makina a CNC. Sekondale iliyonse imawonjezera mtengo. Chifukwa chake ntchito yeniyeni ya uinjiniya ili mu gawo la Design-for-Manufacture (DFM). Kodi tingathe kusintha njira iyi kuti tithetse? Kodi tingasinthire makulidwe a khoma ili kuti tilimbikitse kuphatikizika kofananira kotero kuti kufota kofananako? Nthawi zina, yankho ndi ayi, ndipo muyenera kupanga bajeti ya Machining. Chofunikira ndikukambirana ndi wopanga ufa usanawunidwe. Ndakhala m'misonkhano pomwe tajambulanso gawo lalikulu pa bolodi loyera kuti tiwonetse momwe kusintha kwa radius 1mm kungapulumutse 30% pamtengo wake pothandizira kusindikiza kosavuta-ndi-sinter. Ndiwo mtengo wowonjezera.
Zimagwirizananso ndi zosankha zakuthupi. Chitsulo chochepa chachitsulo cha ufa chikhoza kulowera ku gulu linalake lololera. Ufa wachitsulo chosapanga dzimbiri, wokhala ndi machitidwe ocheperako, ungafunike chipukuta misozi chosiyana kotheratu. Muyenera kudziwa izi kuchokera ku mbiri yakale. Timasunga laibulale yazinthu zocheperako pazinthu zomwe timakonda komanso mabanja a geometry. Si mulingo wofalitsidwa; ndi chikalata chamoyo chamkati, chosinthidwa ndi chilichonse chopanga. Ndiwo mtundu wa chidziwitso chachinsinsi, chothandiza chenicheni kampani ya powder metallurgy amaunjikana.
Supply Chain ndi chinthu chosalimba
Palibe amene amalankhula za chain chain mpaka itasweka. Za a ufa zitsulo ntchito, sikungokhudza kupeza zitsulo ufa. Ndi za kupeza malo oyenera, ndi kugawa kofanana kwa tinthu ndi chemistry. Mtolo wa ufa wokhala ndi kukula kosiyana pang'ono wa tinthu tating'ono ukhoza kusintha kuchuluka kwa kudzaza mu kufa, kusinthira miyeso yomaliza. Tidayenera kuyimitsa zotumizira zonse chifukwa ma cert sanagwirizane ndi mbiri yathu yomwe idatenga nthawi yayitali. Ndi maloto owopsa.
Ndiye pali tooling. Amafa ndi nkhonya. Amapangidwa kuchokera kuzitsulo zapadera, zosagwira ntchito. Chigawo chovuta chikhoza kukhala ndi kufa kwamitundu yambiri ndi nkhonya zingapo zosuntha. Ngati nkhonya imodzi yang'ambika kapena kuvala msanga, mzere wonse wopanga umayima. Nthawi zotsogolera zida zatsopano zazitsulo zitha kukhala masabata 12+. Chifukwa chake mumaphunzira kusunga mndandanda wofunikira wa maupangiri opumira, ndodo zowongolera, komanso ma seti athunthu a magawo apamwamba. Ndi likulu lakufa litakhala pa alumali, koma ndi inshuwaransi. Chowonadi ichi sichimawonekera pazambiri zamalonda zaukadaulo wa PM, koma ndizomwe zimayatsa magetsi. Kampani yomwe ili ndi zaka 30 zakumbuyo, monga gulu kumbuyo Mtengo wa QSY, wakhala akukumana ndi zovuta zambiri ndipo ali ndi maubwenzi ndi ogulitsa kuti ateteze zododometsazo. Ndichinthu chosagwirika koma chofunikira kwambiri.
Ndipo si kuthupi kokha. Ndi kupereka chidziwitso. Katswiri wakale wa atolankhani akapuma pantchito, amakhala ndi chidziwitso chazomwe zimamveka ngati nyimbo yazimitsidwa kapena kusinthika pang'ono pagawo lomwe latulutsidwa kumatanthauza. Kujambula izo pafupifupi zosatheka. Timayesa ndi ma checklists ndi ma sensor data, koma mazenera ena amabadwa kuchokera pazaka zambiri zowonera magawo. Chigawo cha anthu chomwe chili m'gulu lazinthu zogulitsira ndizosalimba kwambiri kuposa zonse.
Kuyang'ana M'tsogolo: Si Gawo Lokha, Ndi Ntchito
Ndiye izi zikuchokera kuti a kampani ya powder metallurgy lero? Omwe azitha kuchita bwino akuchoka pakukhala opereka zigawo. Gawoli ndi njira yopititsira patsogolo. Makasitomala safuna sintered sprocket; iwo akufuna odalirika, otsika mtengo kasinthasintha pagalimoto mawonekedwe. Kodi titha kupereka sprocket, shaft yokwerera yomwe imapangidwa kudzera pa makina a CNC, komanso msonkhano? Kodi titha kulangiza pa ndandanda yamafuta kutengera kulimba kwa zinthu zathu? Ndiko kusintha.
Zimafunika kuphatikizika kozama, ndendende mtundu womwe umawonetsedwa mumakampani omwe amakhala ufa zitsulo, kuponya ndalama, kuumba zipolopolo, ndi makina a CNC pansi pa ambulera imodzi yogwira ntchito. Cholinga ndikukhala ndi zambiri zamtengo wapatali. Zimalola kukhulupirika mwankhanza mu ndondomeko kusankha kwambiri. Nthawi zina, pambuyo pa kuwunika kwa DFM, titha kulangiza kuti gawo lomwe lapangidwa kudzera pa PM litha kugwiritsidwa ntchito ngati kachipangizo kakang'ono kuchokera pamzere wathu wa chipolopolo, kapena billet yopangidwa ndi makina, ndipo titha kuchita izi. Palibe cholimbikitsa kukakamiza kuyenerera kwa PM pomwe sikuyenera.
Pamapeto pake, zimafika pothetsa mavuto, osati kungopanga zidutswa. Ufa ndiye chiyambi cha nkhani, osati mapeto. Ntchito yeniyeni-ntchito yosangalatsa, yokhumudwitsa, ndipo nthawi zina yokhutiritsa kwambiri-imachitika pomvetsetsa momwe chidutswa cha sintered chimagwirira ntchito ndi dziko lapansi: momwe chimamalizidwira, momwe chimasonkhanitsidwa, momwe chimavalira muutumiki. Ndiwo malingaliro. Ndi zochepa za kukhala a kampani ya powder metallurgy ndi zambiri zokhala wopanga mayankho omwe ali ndi zitsulo za ufa ngati chida chofunikira, chomveka bwino mu zida zake. Ndipo, ndikuganiza, ndiyo njira yokhayo yokhazikika yopita patsogolo.
