Kana mainjiniya ataura grey iron casting yeakakwira-duty hydraulic mavharuvhu kana pombi dzimba, ivo havasi kungosarudza chinhu-vari kubheja pakudzikama kwedimensional pasi pekupisa bhasikoro, kutenderera kwe graphite flake kugovera munzvimbo dzekupisa, uye kuvimbika kwepasi mushure mekugadzira. Ndicho chikonzero kusarudza chakanaka grey iron cast kambani hazvisi zvemabhurocha kana zvitupa chete. Iri nezve maitiro akaratidzwa mukugadzirwa kwepasirese: mabatiro anoita tembiricha yekudonha panguva yekuchinja kwemaawa makumi manomwe nemaviri, ingave jecha rayo mold compaction data logs inoteedzerwa kune yega yega yekukanda mijenya, uye kana CNC shopu yayo inogona kubata ± 0.015 mm pane 320 mm bore- * mushure * yekuzorodza pfungwa.
Isu takaona mapurojekiti akawanda achimira nekuti mutengesi aibata grey simbi se "simbi yakangokandwa" - tichiregeredza kuti misiyano midiki yekabhoni yakaenzana (CE), kutonhora, kana shakeout nguva inokonzeresa machinability yemacylinder bores kana inovuza-inovhara nzvimbo. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., grey iron hachisi chinhu chekutengesa. Iyo inodzorwa metallurgical system. Yavo QT450-10 uye GG25 castings inoongororwa spectral * isati yadururwa, neEC yakabatwa mukati me ± 0.08 mapoinzi pamabhechi. Kupisa kwega kwega kunotakura kuteedzera kuzere: melt log, nhamba yeladle, mold cavity ID, uye post-kupisa-kurapa Brinell kuomarara kwechokwadi-kwete chete chitupa chakadhindwa "chinoenderana."
Simba ravo riri mukubatanidzwa kwakatwasuka-kwete sezwi, asi senzira yekuranga. Imba yepiston pombi silinda inotanga sejecha-yakandwa GG25 isina chinhu, yobva yaenda yakananga kune yavo ISO 9001-yakasimbiswa CNC pasi pasina pakati-nzvimbo yekufambisa. Hapana zvakare-clamping zvinoshamisa. Hapana coordination system misalignment pakati pekukanda datum uye machining fixture. Ivo vanogadzira zviso zvakakomba zvekuisa chisimbiso mune imwe setup, vachishandisa Renishaw-probed chishandiso chinobvisa kutsiva kuomarara kwenzvimbo. Ndiwo mabudisiro avanoita 0.4 µm Ra kupedzisa pazvigaro zvevharuvhu-pasina kuputika kwechipiri-uye kuchengetedza 0.02 mm concentricity pakati pebore uye kukwira flange kuyambuka 120 mm kureba. Vatengi kuNorth America vanoshuma 30% mashoma emunda anovuza pane yekutsiva pombi dzimba vachipesana nevatangi vekutanga-nekuti madhizaini ekukanda haana kumanikidza machining ane hukasha akafumura pasi pepasi porosity.
Asi kubatanidzwa kunoreva zvishoma pasina kudzika kwehunyanzvi mune alloy maitiro. Grey iron haina kuparadzaniswa pano-yakagadzirwa padivi pecobalt-nickel masisitimu. Kana mutengi achida mubatanidzwa wehybrid — toti, GG25 pombi hwaro ine AMS 5387 cobalt alloy valve inoisa — timu imwechete inobata ese ari maviri. Vanoziva T800's thermal expansion coefficient i37% yakaderera pane grey iron, saka vanogadzira kupindirana kunopindirana uye annealing cycles izvo zvinodzivirira kutsemuka kwepakati panguva yebasa pa220°C. Uku kuchinjika-kwezvinhu kutsetsenura zvine basa: inodzivirira kudhizainazve kunodhura kana kusawirirana kwemafuta kuchikonzera kutadza kwegasket nguva isati yakwana kana kupfeka kunetseka pamijaho. Takavaona vachigadzirisa graphite morphology kuburikidza neinoculant timing yekuvandudza damping muwinch centre shaft rollers-kudzikisa vibration kutapurirana ne42% mumiyedzo yemumunda painjiniya mota drivetrains.
Chii chinovaparadzanisa kubva kune vatengesi vemabhuku? Nguva yekupindura pane manufacturability mhinduro. Tumira GD&T-inorema dhirowa yemuviri wevhavhavha yekumanikidza, uye iwe unowana akatsanangurwa maPDF mukati memaawa makumi mana nemasere-kwete zvinyorwa zvegeneric senge "kushivirira kwakasimba kunogoneka," asi chaiyo callouts: "Datum C inofanirwa kuchinjisa 0.3 mm yakanangana nebore axis kudzivirira kuvhiringa vhiri," kana "Kutsanangura Rz pachinzvimbo cheRaten kunovandudza pasina muripo wekusimbisa." Protocol yavo yemhando haisi yekutarisa-inofambiswa; ine njodzi-yakarongwa. Inouya mbishi zvinhu inowana spark emission ongororo * uye * ultrasonic bvunzo yemukati shrinkage. In-process macheki anoshandisa maZeiss CMM ane calibrated ceramic styli-kwete aluminium rods-saka thermal drift haina skew results at 20°C ambient. Kuongorora kwekupedzisira kunosanganisira kushanda kumanikidza kuyedzwa pa1.5 × kushanda kumanikidza, nedhayi-inopinda-inopenya yeese mafillet akagadzirwa.
Kana yako inotevera grey iron yekukanda odha ichida zvinopfuura "inokwana uye isingatsemuke," tsvaga humbowo hweyakamisikidzwa maitiro ekudzora-kwete chete kutevedzera. Tarisa zvitoro uko mametallurgists anoongorora mishumo yekugovera zviyo zvejecha pamberi pekugadzira mold, uko CNC programmers inogadzirisa mitengo yekudyisa zvichibva pane chaiyo-nguva kuomarara mepu yekukanda kwega kwega, uye uko misi yekutumira yakasungirirwa kuchoto kutenderera matanda-kwete zvipikirwa zvekutengesa. Icho ndicho chokwadi chekushanda shure kwezvikamu zvakavimbika zvakatendeseka. Zvekukumbira zvikumbiro mu hydraulics, oiri & gasi, kana inorema mota masisitimu, iko kuenderana hakusi sarudzo. Ndiwo mutsauko pakati pekugadzirisa kwakarongwa uye isina kurongeka yekuderera.
