Mukamva 'mtengo waufa zitsulo', nambala yoyamba yomwe imabwera m'maganizo ambiri ndi mawu opangira pa kilo. Ndipamene vuto nthawi zambiri limayambira. Kunena zoona, mtengo wa ufa umenewo ndi tikiti chabe yopita kumasewera. Mtengo weniweni ndi zisankho zingapo, kunyengerera, ndipo nthawi zina, zodabwitsa zosasangalatsa zomwe zimachitika panthawi yopanga. Sikuti amangogula ufa wachitsulo; ndizo zonse zomwe zimachitika mutatsegula thumba.
Chinyengo cha Mtengo Wagawo
Ndakhala pamisonkhano pomwe kugula kumakondwerera kupeza kuchotsera kwa 5% pakusakaniza kwachitsulo-mkuwa-carbon pre-mix. Zimamveka bwino pamapepala. Koma ndiye kupanga kumayamba. Kuthamanga kwake kumachoka pang'ono, zomwe zimapangitsa kuti zisadzaze mosagwirizana m'mabowo a zida zovuta. Mwadzidzidzi, mukukumana ndi kuwonjezeka kwa 2% pakusiyana kolemera, zomwe zikutanthauza kuti makina achiwiri tsopano akuyenera kuwerengera zambiri. Kupulumutsa kumeneko kumasanduka nthunzi gawo loyamba lobiriwira lisanatenthedwe. Kodi tikuphunzirapo chiyani? Ufa wotsika mtengo kwambiri ukhoza kukhala wamtengo wapatali kwambiri pansi ngati mawonekedwe ake - kachulukidwe kampopi, kagayidwe kake kakang'ono - sakufanana ndi kakhazikitsidwe kanu kokanikizira ndi sintering.
Apa ndipamene maubwenzi anthawi yayitali ndi ogulitsa odalirika amafunikira kwambiri kuposa malonda amsika. Kusasinthika kwa morphology ya ufa ndikopulumutsa ndalama zobisika. Kusintha kwa batch-to-batch komwe simukutha kuwona kumatha kusokoneza nyimbo yanu yonse yophatikizika, zomwe zimapangitsa kuti pakhale zida zapamwamba kwambiri kapena, choyipitsitsa, zovuta pambuyo pa sintering. Simukungogula chinthu; mukugula kulosera.
Ndipo tiyeni tiyankhule zosakaniza. Kusuntha kuchokera ku Fe-Cu-C yokhazikika kupita ku ufa wophatikizika-osakaniza kuti ukhale wamphamvu kwambiri? Kudumpha kwa mtengo kumakhala kofunikira, koma kulungamitsidwa nthawi zambiri kumalephera kuganizira zotsatira zakutsika. Nthawi zina, kuti umafunika ufa siters pa kutentha otsika kapena ndi mkombero lalifupi, mwina kupulumutsa ng'anjo nthawi ndi mphamvu. Mtengo wa equation uyenera kukhala wokhazikika. A mtengo wazitsulo wa ufa chitsanzo chomwe chimangoyang'ana P.O. mzere wasweka kwenikweni.
Zida: Silent Budget Killer
Tooling ndiye mtima wa PM, ndipo mtengo wake ndi wapamwamba kwambiri. Invoice yoyamba ya CAD ndi waya-EDM ndi nsonga chabe. Kumene mudatulutsa ndalama ndikukonza, kukonza, ndi kulephera msanga. Ndimakumbukira pulojekiti yopangira chinthu chododometsa - gawo lamitundu yambiri yokhala ndi flange yopyapyala. Mapangidwe a zida adawoneka bwino poyerekezera. M'malo mwake, nkhonya yapansi, yomwe imayambitsa kupanga flange, idayamba kuwonetsa ma fractures pambuyo pa 30,000. Osati kulephera kwathunthu, koma kokwanira kuyambitsa kung'anima pang'ono komwe kumafunikira sitepe yowonjezera yowonjezera. The per-part mtengo wazitsulo wa ufa mwakachetechete idakwera ndi 12% chifukwa cha ntchito yachiwiri yosakonzekera komanso kufunikira kokonzekera zida.
Zomwe zimagwiritsidwa ntchito pazida zokha ndizoyendetsa mtengo wofunikira. Mukugwiritsa ntchito chitsulo chokhazikika pakuthamanga kwambiri kwazitsulo zosapanga dzimbiri? Ndiwo njira yachangu yosinthira zida pafupipafupi. Kukwezera ku premium carbide kapena zitsulo zokutira zitha kuwirikiza mtengo wa zida zoyambira, koma zimatha kuwirikiza katatu moyo wa chida. Kuwerengera sikolunjika. Mufunika zolosera za kuchuluka kwa zinthu zomwe mumakhulupirira. Kwa kanthawi kochepa, zida za premium sizingadzilipirire zokha. Ndi chigamulo chotengera zomwe zachitika, zomwe nthawi zambiri zimapangidwa ndi data yosakwanira.
Ndiye pali khwekhwe ndi kusintha nthawi. Kwa shopu ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., yokhala ndi mizu yozama kuponya ndalama ndi CNC makina, maganizo ndi osiyana. Pamakina, mumakhazikitsa chipika ndipo njira za zida zimayenda. Mu PM, kusintha gawo nthawi zambiri kumatanthawuza kusintha kwathunthu -kugwirizanitsa nkhonya zapamwamba, ndodo zapakati, ndi nkhonya zotsika ndi micron-level yolondola. Ndi maola 4-8 akutsitsa atolankhani. Ngati mukugwiritsa ntchito magulu ang'onoang'ono, mtengo wanthawi yosapanga iyi ukhoza kutsika mtengo wazinthu. Ichi ndichifukwa chake ntchito zosakanikirana, zotsika kwambiri za PM zimakhala zovuta kwambiri kuti zikhale zotsika mtengo; ndalama zobisika za kusinthasintha ndi zazikulu.
Sintering: Kumene Mphamvu ndi Mumlengalenga Zimawononga Mitsinje
Sintering ndiye gawo lamatsenga, koma ng'anjo ndi chilombo chanjala. Mtengo wodziwikiratu ndi gasi kapena magetsi. Zosadziwikiratu, ndipo nthawi zambiri zimakhala zosasunthika, mtengo wake ndi mpweya. Kugwiritsa ntchito mpweya wosiyana wa ammonia (DA) motsutsana ndi nitrogen-hydrogen blend sikungosankha mwaukadaulo; ndi chuma. Mtengo wa ammonia umasinthasintha ndi msika wapadziko lonse lapansi. Chochitika cha geopolitical chikhoza kukweza mtengo wamlengalenga wanu ndi 30% kotala, ndi chenjezo lopanda chenjezo.
Ndawonapo zoyesayesa zochepetsera ndalama powonjezera ma sintering cycles kapena kuchepetsa kutentha kuti tisunge mphamvu. Nthawi zonse zimabwerera m'mbuyo. Zigawo zomwe sizinachuluke kwambiri kapena kulimba, zimadzetsa kukana kwambiri pakatenthedwe kapena kukonza makina. Kapena choyipa kwambiri, zigawozo zimadutsa QC yoyamba koma zimalephera pakuyesa kumunda chifukwa cha kutopa. Kupulumutsaku kumasanduka ngozi ya mbiri komanso zachuma. Chinsinsi cha sintering ndi pangano; kupatuka kwa izo kuti apulumutse 1 tambala kumawononga madola.
Kukonza ng'anjo ndi bokosi lina lakuda. Mphepo yotayira kapena thermocouple yolakwika sikungosiya kupanga. Ikhoza kupanga mpweya wotsekemera mkati mwa ng'anjo, kuwononga gulu lonse la magawo. Kumeneko sikungotayika chabe ufa zitsulo zakuthupi ndi ntchito; ndiye mtengo wa mwayi wosowa kutumiza. Madongosolo okonzekera bwino ndi mtengo wosakambitsirana pochita bizinesi, koma nthawi zambiri amakhala chinthu choyamba chofinyidwa pamene oyang'anira akufunafuna kuchita bwino.
Zotsatira zake: Ntchito Zachiwiri ndi QSY Parallel
Kawirikawiri gawo la PM limatuluka pa lamba wokonzekera kutumizidwa. Ambiri amafunikira china chowonjezera - kukula kwake, ndalama, kuthira mafuta, kutenthetsa, kapena kukonza makina. Apa ndi pamene chiwerengero mtengo wazitsulo wa ufa zimafika poyang'ana, ndipo zomwe timakumana nazo muzochita zina zimapereka kufananitsa kwakukulu.
Tengani zida za sintered zomwe zimafuna njira yolumikizira. Mwagulitsa kale ufa, compaction, ndi sintering. Tsopano mukuyiyika pa makina a CNC broaching. Vuto ndilakuti zida za sintered, ngakhale zitakhala zolimba kwambiri, zimatha kukhala zowopsa. Amatafuna zida zodulira mwachangu kuposa mnzake wachitsulo. Mtengo wanu wamakina pagawo lililonse ndiwokwera kwambiri. Iyi ndi synergy yomwe timagwiritsa ntchito Mtengo wa QSY. Kukhala CNC makina ukatswiri m'nyumba umalola kupanga njira zophatikizika. Titha kusintha kapangidwe ka zida za PM kuti tisiye katundu wocheperako panjirayo, kapena kutchula aloyi yosiyana pang'ono yomwe imapangidwa mwaukhondo, kukhathamiritsa mtengo wonse panjira zonse ziwiri.
Uwu ndiye mwayi wopanga vertically Integrated. Mukawongolera zonse kupanga (monga chipolopolo nkhungu kuponyera kapena PM) ndi kumaliza (CNC makina), mukhoza kupanga malonda. Mwina chinthu chomwe chimakhala chokwera mtengo kwambiri kuchisindikiza ndi sinter chikhoza kuwonjezeredwa pazachuma kudzera mu sitepe yofulumira ya makina pambuyo-sintering. Kapena, monga tikuonera kuponya ndalama za ma aloyi apadera, nthawi zina kusintha ndondomeko yonse kwa gawo lovuta, laling'ono laling'ono ndilofunika kwambiri kuposa kuyesa kukakamiza ku PM kufa. The mtengo wazitsulo wa ufa si chilumba; ndi gawo la zisumbu zopanga.
Volume: The Great Arbitrator of Cost
Chilichonse mu PM chimalozera ku voliyumu. Mtengo wokwera wokhazikika wa zida ndi kukhazikitsa uyenera kuchepetsedwa. Ili ndiye lamulo lofunikira. Gawo lomwe limawononga $ 10 mu ufa ndi kukanikiza zidutswa 100,000 zitha kuwononga $50 pachidutswa chilichonse pakuthamanga kwa 5,000. Masamu ndi ankhanza komanso opanda mzere.
Ndinachita nawo ntchito yolephera yopezera nyumba ya sensor. Gawoli linali loyenera kwa PM-mawonekedwe ovuta, zinthu zabwino zakuthupi. Tinagwira mawu kutengera kuchuluka kwapachaka kwa 50k. Wogulayo adakonda mtengo wake. Kenako ntchito yawo inayimilira, ndipo anaitanitsa koyambirira kwa 5k. Mtengo wathu watsika. Tinayenera kudya mtengo wa zida, ndipo mtengo wagawo lililonse unali wosakhazikika. Tidaphunzira kupanga zodziwikiratu zamphamvu kwambiri m'mawu ndikukhala oona mtima mwankhanza ndi makasitomala pazachuma. Nthawi zina, kwa prototype kapena voliyumu yotsika kwambiri, kulangiza kasitomala kugwiritsa ntchito a makina kapena kuponya ndalama Njira kuyambira pachiyambi, ngakhale mtengo wa gawo lililonse ukuwoneka wokwera, ndiyo njira yowona mtima komanso yopambana.
Choncho, pamene inu kusanthula mtengo wazitsulo wa ufa, musamangoyang'ana pa spreadsheet. Ganizirani za ufa womwe ukuyenda mu nsapato, kuvala kwa nkhonya ya tungsten carbide, kusasinthasintha kwa mpweya wa ng'anjo, ndi phokoso la mphero ya CNC yomaliza datum pamwamba. Mtengo uli mu mphindi zonsezo. Ndi mtengo wa ndondomeko, osati mtengo wakuthupi. Ndipo kuchikonza kumafuna kukhala ndi moyo ndi ndondomekoyi, kupyolera mu zovuta zake ndi zodabwitsa, osati kungowerengera patali.
