Pamene mainjiniya amatchula a kuponya zitsulo gawo fakitale, sikuti amangoyitanitsa zinthu zina - amateteza kukhulupirika kwapangidwe pansi pa 300 bar hydraulic pressure, kukhazikika kwa dimensional pambuyo pa kutentha kwa 500 ° C, kapena kukana kuvala m'malo otsekemera a slurry. Ichi ndichifukwa chake tawona makasitomala akubwerera katatu kwa okondedwa omwewo: osati pamtengo wotsika kwambiri, koma chifukwa cha ziro-first-run scrap pa AMS 5387 cobalt alloy pump housings, kubwereza GD&T kutsatiridwa pa bore za piston cylinder, ndi kufufuza kwathunthu kwa zinthu mpaka kusungunula batch ndi lipoti loyesa.
Chifukwa chiyani kusankha kwa fakitale yachitsulo kumalephera - makina asanayambe ngakhale kuyamba
Magulu ambiri ogula zinthu amawona kuponya ngati chinthu chofunikira. Sazindikira kuti 68% ya kusakhazikika kwapang'onopang'ono m'matupi othamanga kwambiri amachokera ku mapangidwe a nkhungu-osati mapulogalamu a CNC. Taziyeza: nyumba zachitsulo zoponyedwa mchenga zokhala ndi zoziziritsa zosalamulirika zimawonetsa kupotoza kwa 0.042 mm pambuyo popuma kupsinjika. Magawo a cobalt a T800 otayira ndalama amachepa mosadziwika bwino ngati kukulitsa kwa sera sikungafanane ndi chinyezi komanso kutentha. A zoona kuponya zitsulo gawo fakitale sichimangothira zitsulo - imawonetsa kugawa kwamafuta ambiri, imatsimikizira kuyerekezera kolimba motsutsana ndi mawonekedwe enieni, ndikusintha chitseko chisanayambe kuthira koyamba.
Umu ndi momwe QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapereka makulidwe osasinthasintha a khoma mu maziko a pampu 120 mm-mosasamala kanthu za njira zoziziritsira mkati zovuta. Mapangidwe awo ogwirizana ndi ISO amayendetsa ntchito zofananira ndi kupanga makina. Chifukwa chake kasitomala akatumiza chojambula cha mphuno ya aloyi ya cobalt yomwe si yokhazikika, mainjiniya amayang'ana kuthekera koponyera * asanatchule mawu akuti: "Kodi utali wa 3.2 mm uwu ungakhalebe ndi kulimba? Inde, timagwiritsa ntchito ma cores a ceramic ndi kuzirala kolowera. Palibe zongoganizira. Basi zitsulo chifukwa-ndi-zotsatira.
Maluso anayi omwe amalekanitsa makina olondola kuchokera kwa ogulitsa zinthu
- Cobalt-nickel alloy mastery-osati kungogwira, koma kukhathamiritsa: AMS 5387 si makina; ndi kukhumudwa. Malo awo ogulitsira amagwiritsa ntchito zida za carbide zokhala ndi ma angles a 8 ° negative, zoziziritsa kusefukira pa 42 bar pressure, komanso kugwedera kwanthawi yeniyeni pamagiro a 5-axis. Zotsatira: Kumaliza pamwamba Ra ≤ 0.8 µm pazibowo zamkati za mapulagi a aloyi a cobalt, popanda kung'amba pang'ono.
- Kuphatikizika koyima komwe kumalepheretsa kulolerana kukwera: Kuponyera mchenga, chithandizo cha kutentha, CNC Machining, ndi CMM kuyendera kumachitika pansi pa denga limodzi. Palibe wogulitsa kutentha kunja komwe amasinthira kuuma. Palibe chopukusira chachitatu chomwe chikuyambitsa kutha. Pamene winch center shaft roller imafuna HRC 58-62 kuuma kwapamtunda * ndi * 0.008 mm Total indicator reading (TIR), kulumikizana kumeneku kumangokhala ndi njira yotseka.
- Geometry yogwira ntchito pa zodzikongoletsera: Akatswiri awo amakana zojambula zomwe zimatchula "kusintha kosalala" popanda kufotokozera coefficient kapena kutsika kwa kuthamanga. M'malo mwake, amatengera mphamvu zamadzimadzi m'malo ovuta - kenaka amasintha ma radii a fillet, ma angles ojambulira, ndi malo a zipata kuti akwaniritse magwiridwe antchito, osati kungosindikiza.
- Traceability yomwe imayankha mafunso enieni: Osati “gawo ili linapangidwira kuti?” koma “Ndi gulu liti lothira kutentha lomwe linasonyeza kulimba kwa 12% pa −40°C? Chigawo chilichonse chofunikira chimakhala ndi nambala ya QR yolumikizana ndi ma cert, zipika zozungulira matenthedwe, malipoti a CMM, ndi zolemba zowonera.
Mtengo wobisika wa "kubwereza mwachangu, kutumiza mwachangu" akulonjeza
Mafakitole ena amalonjeza nthawi zotsogola za milungu itatu pakupanga zitsulo. Tayang'ana zomwe zikuchitika kenako: 22% rework rework pa valve pressure chifukwa cha subsurface porosity yosazindikirika; Kuchedwa kwa masiku 3.7 pamene chithandizo cha kutentha chimasonyeza kuuma kosagwirizana; $ 18,000 pamayendedwe apamlengalenga kuti alowe m'malo mwa nyumba imodzi yolephera pampu ya pisitoni yomwe idaphonya kuyesa ntchito.
QINGDAO QIANGSENYUAN simakonzekeletsa kuthamanga kwa kalendala. Amakonzekera *kuchita bwino koyamba *. Kukonzekera kwawo kokonzekera kumaphatikizapo kuwunika ziwopsezo zisanayambike: "Kodi kuponyera kopanda banga kwa 17-4PH uku kungasokonekera panthawi yochotsa njira yothetsera vutoli? Inde, ndiye timawonjezera mikombero yochepetsera kupsinjika * tisanagwiritse ntchito makina omaliza." Kuyenda kwawo kowonda kumatanthawuza kuti palibe vuto poyang'anira - ma CMM amayendetsa 24/7, ndikutulutsa lipoti lokha lolumikizidwa ku ERP. Prototype imayitanitsa sitima m'masiku 18 - osati chifukwa chothamangira, koma chifukwa amachotsa kuyambiranso koyambirira.
Zoyenera kutsimikizira-Musanasaine PO
Funsani wanu kuponya zitsulo gawo fakitale mafunso asanu awa-ndipo amafuna umboni wolembedwa:
- "Ndiwonetseni malipoti atatu omaliza a CMM a gawo lomwe likugwirizana ndi kuyitanidwa kwathu kwa GD&T - makamaka mbiri ndi kulolerana kwamaudindo."
- "Perekani chipika chosungunula ndi lipoti loyeserera la cobalt alloy batch lomwe lagwiritsidwa ntchito posachedwa kwambiri pa AMS 5387."
- "Kodi mumatsimikizira bwanji kayesedwe wokhazikika motsutsana ndi ma microstructure enieni? Gawani chithunzi chodutsana ndi muyeso wa dendrite wotalikirana ndi mkono."
- "Kodi kupatuka kwanu kovomerezeka ndi kotani pakati pa miyeso ya as-cast ndi makina omaliza azitsulo zachitsulo za 300 mm?"
- "Chojambula chikanena za 'kuyesa kosawononga pa ASTM E186', ndi antchito ati omwe ali ndi chiphaso cha ASNT Level II - ndipo mayeso awo omaliza anali liti?"
Awa si macheke amalingaliro. Ndi zosefera zomwe zimawululira ngati wogulitsa akuwona ngati uinjiniya-kapena ngati kungoyerekeza.
A odalirika kuponya zitsulo gawo fakitale samagulitsa magawo. Amagulitsa kulosera. Zimatsimikizira kuti phokoso la alloy cobalt silingawonongeke pa 12 m / s slurry velocity. Kuti chitsulo choponyera chitsulo chimakhala ndi 0.02 mm flatness kudutsa 800 mm pambuyo pa njinga yamoto. Kuti katundu aliyense amafika ndi deta-osati mapepala okha. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga kudalirika kumeneko mu kamangidwe kake, osati malonda ake. Chifukwa m'makina a hydraulic, zida zamafuta, ndi nsanja zamagalimoto opangidwa ndi injiniya, palibe mwayi wachiwiri wakulephera kwapang'onopang'ono.
