Kukandwa kwejecha kunoramba kuri kunonyanya kushandiswa kwesimbi kuumba maitiro-inoverengera inopfuura 70% yezvese zvinokandwa zvinogadzirwa pasi rose. Asi kune vatsva vanopinda mune imwe nheyo, nhamba huru ye zvikamu zvekukanda jecha anogona kunzwa kuremerwa. Mapeteni, cope uye kudhonza, sprues, risers, cores, magedhi-chimwe nechimwe chine basa risingagone kutaurirana kana kukanda kunobuda mutsindo kana zvimedu.
Isu takaona akawanda ekutanga-nguva mainjiniya achikanganisa mutsara wekuparadzanisa panguva yekuungana kweforoma. Isu takaona nyanzvi dzine ruzivo dzichifuratira kuiswa kwemhepo-uye kuzopedzisira nehomwe dzegasi mumitumbi ye hydraulic valve. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kwatinogadzira simbi chaiyo uye simbi yekukandira dzimba dzepombi inotsikirira necobalt-alloy nozzles, chikamu chose chejecha mold chinosimbiswa-kwete kufungidzirwa. Ngatitarisei zvakakosha zvikamu zvekukanda jecha, kwete sekutsanangurwa kwebhuku, asi sezvinhu zvinoshanda zvatinovimba nazvo zuva nezuva kuendesa zvikamu zvinobata 350+ bar kudzvanywa pasina kuvuza.
Izvo Zvikamu Zvikuru Zvaunofanirwa Kunzwisisa Usati Wadira
Jecha rekukanda mold haringori jecha rakazara. Iyo yakanyatso kugadzirwa sisitimu yakagadzirirwa kudzora kuyerera kwesimbi, kusimba kwekudya, uye kuburitsa magasi akavharirwa. Heano zvikamu zvishanu zvisingagone kutaurirana-uye chii chinoitika kana chero munhu akakundikana:
- Muenzaniso: Mufananidzo wakazara wechikamu chekupedzisira-chinowanzo gadzirwa nematanda, epurasitiki, kana aruminiyamu yemuchina. Kururama kwayo kunotsanangura zvakananga kushivirira kwedimensional. Isu tinoshandisa CNC-yakagadzirwa aruminiyamu mapatani ehumburumbira dzimba nekuti inobata ± 0.15 mm pamusoro pe400 mm kureba-yakakosha kana machining chisimbiso nzvimbo post-cast.
- Cope uye Dhonza: Pamusoro (kutsungirira) uye pasi (dhonza) mold halves. Chimiro chavo ndiwo mutsara wekuparadzanisa. Kusarongeka pano kunogadzira flash iyo inofanirwa kunge yakadzikwa-inodhura rework nhanho yatinodzivirira nekushandisa dowel-pini kunyoreswa pane ese ekugadzira mold.
- Sprue: Mugero wakatwasuka unopinda nawo simbi yakanyungudutswa mumhango ye mold. Kunyanya kutetepa? Turbulence inowedzera kuumbwa kweokisijeni. Zvakafara zvikuru? Kusashanda zvakanaka kwekudya. Kune yedu T800 cobalt alloy pombi zvikamu, isu saizi sprues zvichibva pane metallostatic musoro kuverenga-kwete mutemo-we-chigunwe machati.
- Riser: Dziva rakaiswa pamusoro kana padivi pekukandira kudyisa shrinkage panguva yekusimba. Chikanganiso chinowanzoitika: kudzikisa pasisiers kune zvikamu zvakakora. Mune imwe batch yepiston pombi cylinder housings, kusakwana kwekusimudza vhoriyamu kwakakonzera centreline porosity-inongoonekwa panguva yekuongorora kwe ultrasonic. Iye zvino isu tinotevedzera kusimba ne MAGMAsoft pamberi pekugadzira mold.
- Core: Ijecha rakasiyana rinopinza rinoumba maburi emukati—sezvinoita mavharuvhu kana kuti mabhomba. Macores anofanirwa kumira metallostatic pressure uye thermal shock. Isu tinoshandisa makemikari akasungwa silica jecha nefuran resin yekusimba kwepakati, tozobika pa220 ° C kwemaminitsi makumi mapfumbamwe. Makori asina kubikwa anodonha pasi pe1,450°C simbi yakanyungudutswa.
Nei Gedhi Dhizaini Inoparadzanisa Yakavimbika Castings Kubva Zvimedu
Magedhi-matanho anobatanidza sprue kune mhango-haawanzo kukurukurwa, asi iwo anosarudza kuvimbika kwepamusoro, chimiro chezviyo, uye kugovera kusanganisa. Vamwe vanogona kupokana nzvimbo yegedhi ndeyechipiri kune pateni dhizaini. Nekudaro, muchiitiko chedu neAMS 5387 cobalt alloy 6 zvikamu, geji risiri iro rinokonzeresa kutadza kudzokororwa katatu: kutonhora kuvharika padhuze nemadziro matete, kukukurwa kwejecha munzvimbo dzinomhanya-mhanya, uye kunyura kwemarara panzvimbo yekupinda mukati.
Isu tinoshandisa yepasi-gedhi kune akareba, akatetepa-amadziro edzimba kuderedza mhirizhonga. Kune zvikamu zvakaenzanirana senge winch centre shaft rollers, isu tinoisa akawanda eradial magedhi-eve nechokwadi kuzadza yunifomu uye kusimba kwekutungamira kune anosimuka. Yese gedhi muchinjiko-chikamu chinoverengerwa uchishandisa Bernoulli musimboti wakagadziridzwa simbi viscosity uye tembiricha inodonha. Iyo haisi dzidziso-ndiwo maitiro atinoita Cpk> 1.33 pamadhayamita akakosha mhiri kwe500+ kugadzirwa kunomhanya.
Zvinotariswa neVatangi: Vents, Sanding Sand, uye Shakeout Nguva
Maburi maburi madiki — anowanzo 1–2 mm dhayamita — anoboorwa nepacope kana kudhonzwa kuti mweya nemagasi ekuumbwa zvibude. Svetuka iwo, uye iwe unowana mapinho kana maburi. Isu tinodhiza mavheti nemaoko mushure mekugadzira mold, tichiaisa panzvimbo yekupedzisira-yekuzadza-inotaridzirwa mukuenzanisa. Hapana otomatiki-nekuti kupfeka kwechishandiso kunoshandura gomba geometry, uye kusapindirana kwemhepo kunoparadza microstructure.
Jecha rinopatsanura—iyo yakatsetseka yakapfava pakati pecope and drag—inofanira kuva yakaoma, isina kuyerera, uye isingabatanidzi. Isu tinoshandisa calcined alumina poda, kwete graphite. Graphite inonamira hunyoro mukati me mold interface uye inosimudzira kukanganiswa kweveining musimbi isina tsvina castings.
Shakeout nguva inonyanya kukosha kupfuura zvinofungwa nevakawanda. Kubvisa zvinokandwa nguva isati yakwana kunokonzeresa kutsemuka kwemafuta-kunyanya mu-high-carbon iron. Kunonoka, uye kupisa kwakasara kunokonzera kukanganisa munzvimbo dzakagadzirwa nemichina. Yedu chiyero: mhepo-inotonhorera castings kusvika pamusoro tembiricha yadonha pasi pe150 ° C, yakasimbiswa neruvoko IR mathermometers-kwete matermers.
Kubva kuMold kuenda kuMishinari-Yakakosha Chikamu: Iko Jecha Kukandwa Kwakakodzera Nhasi
Kukandira jecha haisi yenhaka tekinoroji-ndiyo hwaro hwekugadzira yakasanganiswa. PaQINGDAO QIANGSENYUAN TECHNOLOGY, tinobatanidza machira ejecha-akakanda ane akawanda-axis CNC machining, kupisa kupisa, uye kupera kwepamusoro-zvose pasi pedenga rimwe rinoenderana neISO. Kudzora kwakatwasuka kunoita kuti tivimbise kutevedza kweGD&T pazvinhu zvakaita senge concentricity yebore-to-flange (± 0.05 mm) kana kushata kwepamusoro Ra ≤0.8 µm pakusunga zviso.
Kana iwe uri kutsanangura yekumanikidza vharafu imba kana engineering mota winch chikamu, kunzwisisa iyo zvikamu zvekukanda jecha zvinoreva kuziva pakamira shiviriro, panotangira kukanganisa, uye kuti sarudzo dzekugadzira dzinokanganisa sei mutengo uye nguva yekutungamira. Zvinoreva kubvunza kwete "Inogona kukandwa here?" asi “Chiumbwa chimwe nechimwe chichaita sei pa1,520°C nenguva yokudira yemasekondi gumi nemaviri?”
Ndiwo mutsauko uripo pakati pekudhirowa uye chinotakurika. Uye ndosaka vatengi vedu-kubva kuNorth America kuenda kuSoutheast Asia-vanotitumira GD&T-rich dhizaini ine yakasimba metallurgical specs, kwete zvikeche chete. Nekuti ivo vanoziva mold haingori mudziyo. Ndiyo nhanho yekutanga yekutonga kwehutano.
