Kana mainjiniya akatsanangura grey iron castings, havasi kungoodha zvikamu - ivo vari kuzvipira kune hwaro hwekudzikama kwedimensional, vibration damping, uye refu-refu kupfeka kuramba pasi pemitoro chaiyo yenyika. A grey iron castings fekitori izvo zvinozadzisa zvipikirwa izvozvo hazvivimbi nekutaura kwakakura. Iyo inozviratidza muiyo microstructure yekudururwa kwega kwega, kudzokororwa kweyese machining kutenderera, uye kuteedzera kuseri kwese kwese-kupisa-kupisa batch.
Kururamisa Kunotanga neKudzorwa Kubatanidzwa-Kwete Kungozadza Mold
Isu takaona mapurojekiti akawandisa achimira pabvunzo yekutanga inoshanda-kwete nekuda kwekukanganisa kwedhizaini, asi nekuti kugovera kwegraphite flake kwaisaenderana neinodiwa ASTM A48 Kirasi 30B kusimba kwesimba kana kuomarara chimiro. Grey iron haisi "nyore" iron. Kuita kwayo kunotsamira pakudzora kwakasimba pamusoro pekabhoni yakaenzana (CE), kutonhora rate, inoculation nguva, uye kuoma kwe mold. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., jecha rega rega rinotanga nekuongororwa kwekemikari yeladle - kwete kungoumbwa chete, asi kugona kweokisijeni uye mazinga etitanium asara. Ndiwo mabatiro atinoita nguva dzose ± 0.15 mm pazvibhorani zvakakosha mupiston pombi silinda dzimba, kunyangwe pamadziro akakora kubva pa12 mm kusvika 65 mm.
Vatengi vanowanzobvunza kuti: "Unogona kukanda miviri yakatetepa-yakavharirwa mavharuvhu pasina shrink porosity?" Ehe-asi chete kana gating dhizaini yakasimbiswa kuburikidza ne MAGMAsoft solidification simulation * pamberi * pateni kubvumidzwa, uye kana epakati prints akagadzirwa kuti arambe kufamba panguva yekuzunza. Hatibati kukanda sebhokisi dema. Isu tinomepu anodziya magradients munguva chaiyo tichishandisa yakadzamirirwa thermocouples panguva yekufanirwa kumhanya. Iyo data inodyisa zvakananga muCNC yekumisikidza yedu-saka machining inotsiva inofanotaurwa inotungamira shrinkage, kwete kufungidzira.
Kugara Kunoda Kubatanidzwa Kwakajeka-Kwete Kungokanda kana Kugadzira wega
Vamwe vatengesi vanoregedza castings kune vechitatu-bato machinists. Izvo zvinogadzira mikaha: kutendeseka kwepamusoro kunoshatisa pakati pekuputika kwepfuti uye kutendeuka kwekupedzisira; kupisa kwekurapa kukanganiswa kunoenda kusingayerwe kusvika kuongororwa kwekupedzisira; GD&T callouts senge chinzvimbo kushivirira Ø0.05 mm hukama kune yakakandwa datum inove isingagone kubata. Pane yedu ISO-inoenderana nzvimbo muQingdao, grey iron castings inofamba isina musono kubva pakubata kuenda kune yakawanda-axis CNC-hapana kutamiswa kwekunze, hapana kugadzirisa patsva, hapana kurasikirwa kwekuenderera kwedatum.
Kubatanidzwa uku kunopa mhedzisiro inoyerwa:
- Kupera kwepamusoro pazvigaro zve hydraulic valve zvakabatwa kuRa 0.8 µm-pasina kupeta kechipiri-nekuti machining anotevera mukati memaawa makumi maviri nemana ekurerutsira-kurerutsa.
- Microhardness kuenderana pamadziro akabhowa (210-230 HBW) yakasimbiswa neRockwell B kuyedzwa * mushure me* yekupedzisira kupisa kupisa, kwete zvisati zvaitika.
- Kuteedzera kuzere: Chikamu chega chega chinotakura laser-etched lot ID inobatanidza kumashure kunyunguduka kuongororwa, kukanda zuva, kupisa kupisa curve, uye CMM chirevo.
Ndosaka mainjiniya emota winch centre shaft rollers-zvichienderana nekukotama uye kubata abrasive-inogara ichipfuura zviuru gumi nezviviri zvehupenyu hwemumunda muEuropean OEM deployments. Durability haina kuwedzerwa gare gare. Yakagadzirirwa mukati mekushanda.
Kuvimbwa Kunowanikwa Kuburikidza Nekujeka-Kwete Zvitupa Pamadziro
"ISO yakasimbiswa" inoreva zvishoma kana zvitupa zvezvinhu zvinouya zvikasatariswa pamishumo yebvunzo yeguyo-kana kana ongororo yakaitwa padanho rekupedzisira. Isu tinocherekedza kutevedza kwezvakagadzirwa *pasati* kunyunguduka: ongororo yakaitwa yenguruve iron, zvimedu zvekuchaja ratios, uye ferroalloy akawedzera anoiswa uye anochengetwa. Yese grey iron casting inopinda matatu anosungirwa kutarisa nzvimbo:
- Kupinda kwezvinhu zvekuongorora (spectral + tensile sampu pakupisa)
- Mu-process CMM scan yeakakosha datums mushure mekukashama machining
- Yekupedzisira optical kuyerwa kwekuisa chisimbiso nzvimbo uchishandisa 5-micron resolution yekuona masisitimu
Hapana kunze - kunyangwe kune prototypes. Mumwe mugadziri wepombi wekuNorth America akawana izvi panguva yavo yechipiri: dhizaini yavo yakadzokororwa yaisanganisira yakaomesesa flatness spec pane inokwira flange. Chikwata chedu chakachiratidzira panguva yekuongorora kweinjiniya-kwete nekuramba, asi nechikumbiro chekugadzira: kushandura dhamu rekukanda kudzikisa kukanganisa-kukonzeresa kutsauka. Vakazvibvumira. Chekutanga-chinyorwa chekugamuchira mwero chakakwira kubva pa68% kusvika pa100%.
Nei Global Engineers Vachidzokera kune Iyi Grey Iron Castings Factory
Haisi yemutengo wakaderera. Ndezvekubvisa njodzi yakavanzwa-iyo mhando inowanikwa panguva yekuyedzwa kweFAT kana, zvakanyanya, mumunda. Kana vharuvhu yako ichifanira kuvhara pa 350 bar kwemakore makumi maviri, kana pombi yako nheyo inoramba resonant frequencies kusvika 1,200 Hz, fungidziro inodhura kupfuura chaiyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda uko metallurgy inosangana nemakanika: maitiro ekukanda akarongedzerwa nzvimbo dzakati dzesevhisi, machining marongero anoenderana negraphite morphology, uye mhando mapuroteni akagadzirirwa chinangwa-chakakosha kuzvidavirira. Isu tinoshandira vatengi vanoda grey iron castings inoita-kwete kungosvika.
Tichitarisa kumberi, yedu R&D tarisiro inoramba iri pahybrid casting-machining optimization: kudzikisa yakazara yekutungamira nguva yedzimba dzakaomarara pasina kupira microstructural kutendeseka. Nekuti kusimba hakuyerwe mumakore chete. Inoyerwa mukuvimba - pese nguva iyo system inosimuka.
