Kusarudza zvakanaka metal cast maitiro haasi ekutora zita kubva pane rondedzero. Zviri zvekufananidza fizikisi, geometry, uye basa - mold yekutanga isati yadururwa. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Takakanda zvikamu gumi nezviviri zvakasiyana zvemavharuvhu ehydraulic, dzimba dzepombi, uye mawinji ekumahombekombe. Kukundikana kwese kwakatidzidzisa chimwe chinhu kongiri: kukanda jecha hakuzobati ± 0.05 mm pane cobalt-alloy nozzle seat; mari achikanda makatsemuka kana ukasvetuka preheat pamusoro AMS 5387; uye centrifugal casting inokundikana zvakashata apo mudhuri wemadziro unodonha pasi pe 18 mm pa-high-pressure cylinder liners.
Tanga nechikamu-kwete maitiro
Mazhinji mainjiniya anotanga nekubvunza kuti "Ndeipi nzira yekukanda simbi iri nani?" Mubvunzo iwoyo unoita kuti uwedzere kutarisisa kana kusashanda zvakanaka. Pane kudaro, bvunza zvinhu zvitatu: Ichatakura mitoro ipi? Painokundikana mubasa? Ndeapi dimensional kushivirira anofanirwa kupona machining ekupedzisira?
Takambogamuchira dhirowa yeT800 cobalt alloy piston pombi yedzimba-yakanangana ne350 bar operation. Mutengi akatsanangura kukanda jecha. Asi mushure mekupisa kwekushushikana kwekuenzanisa uye microstructure ongororo, isu takakurudzira kukanda mari nekudzora kusimba. Sei? Kukandwa kwejecha kwakagadzira chimiro chezviyo chisingaenderane padyo nevhavha port interface. Maviri ebvunzo mayuniti akatsemuka pa280 bar panguva yekuputika kuyedzwa. Investment casting yakaunza yunifomu yedendrite ruoko spacing, yakapfuura 420 bar kusimbiswa, uye yakaderedza post-machining zvimedu kubva pa37% kusvika 9%.
Iyo yekutora: Geometry inotyaira maitiro sarudzo. Yakatetepa-madziro, yakaoma contours ine yakasimba GD&T kudana kwekudyara kukanda. Heavy-section structural bases? Kukandira jecha kunopa zvirinani kudzora mutengo uye kugadzikana kwekupisa. Rotational symmetry ine yunifomu yemadziro ukobvu? Centrifugal casting inopa huwandu hwepamusoro uye hupenyu hwekuneta-kunyanya kune simbi isina tsvina yepombi nheyo dzakafumurwa nekukukurwa kwemvura yemunyu.
Material inotsanangura sirin'i yako-uye miganhu yako
Iwe haugone kukanda chausingakwanise kudyisa. Cobalt-nickel alloys akaita seAMS 5387 uye T800 ane yakakwirira kunyunguduka (1370-1420 ° C), yakaderera fluidity, uye yakanyanya kunzwisiswa kune mold tembiricha gradients. Takaona zvitoro zvichiedza kuvamanikidza kuita girinhi-jecha mold-kungowana zvivharo zvinotonhora, kupera porosity, uye interdendritic kuparuka. Aya haasi "maitiro akakundikana." Iwo zvinhu-maitiro kusawirirana.
Nzvimbo yedu inomhanyisa mitsetse miviri yakafanana yekukanda: imwe yakagadziridzwa simbi uye kabhoni simbi (jecha kukanda, kusvika 500 kg), imwe yakatsaurirwa kune yakakwira-alloy superalloys (investment casting, vacuum-assisted pour, preheated ceramic shells). Kune AMS 5387 nozzles, isu tinoshandisa silica-based shell masisitimu preheated kusvika 1050 ° C - kwete 800 ° C - kudzivirira kupisa kwekupisa uye kuona kuti mold yakazara. Iyo imwe chete parameter shanduko yakacheka mukati oxide inclusions ne 63% muongororo yedu yekupedzisira yemwedzi gumi nemasere.
Usafunga kuti "simbi isina tsvina" inoreva chinhu chimwe. 316 isina tsvina inoita zvakasiyana zvakanyanya pane 17-4PH kana F22. Uye cobalt alloys inoda akasiyana gating, kusimuka, uye kutonhora mazano pane nickel-based Inconels. Kana mutengesi wako akasabvunza yako yakazara metallurgical spec sheet-kusanganisira nhoroondo yekupisa yekurapa uye inodiwa tensile/impact values - iwe watove kumashure.
Kubatanidzwa kunokunda kuzviparadzanisa-nguva dzose
Kukandira kwakakwana hakubatsiri kana kusingakwanise kugadzirwa kuti kudhindwe. Isu tinoona izvi zuva nezuva: mutengi anoodha jecha-akakanda simbi hwaro, obva adaidzira ± 0.025 mm kupfava pamusoro pe600 × 400 mm pamusoro. Hazvigoneki pasina kuzorora kwekushushikana uye kunyatsogadzirisa. Kana iyo yekudyara-yakakanda cobalt plug inosvika iine 0.3 mm kupenya pamutsara wekuparadzanisa-inozorambwa nekuti chitoro cheCNC chinoshaya maturusi anobhowa eiyo 3.2 mm yemukati shinda.
Ndicho chikonzero QINGDAO QIANGSENYUAN TECHNOLOGY ichibatanidza kukanda, kupisa kupisa, akawanda-axis machining, uye CMM kuongorora pasi peimwe ISO-inoenderana nedenga. Kana tichitaura nezvemuviri wevharuvhu yekumanikidza, tinotevedzera mafambiro ese ebasa: kukanda shrinkage muripo, kunetseka-kuzorodza kutenderera nguva, dhizaini yekugadzira yakatetepa-madziro clamping, uye yekuona kuyerwa kwenzvimbo dzakakomba dzekuisa chisimbiso. Isu hatisi kupa zvikamu-tinopa zvikamu zvakasimbiswa zvinoshanda.
Uku kubatanidzwa kunocheka nguva yekutungamira ne31% pane yepakati-vhoriyamu maodha uye kubvisa 94% yedimensional rework. Zvinotonyanya kukosha, zvinoita kuti tigadzirise matambudziko asati avapo-sekugadzirisa gating kudzikisa kusara kunetseka muwinch centre shaft roller kuitira kuti kugaya kwekupedzisira kuwane Ra 0.4 µm pasina chatter.
Bvunza mibvunzo yakakodzera-usati wazvipira
Usati wasarudza a metal cast shamwari, simbisa aya mapoinzi mashanu:
- Vanosimbisa maitiro avo ekukanda-kwete kungoongorora mhedzisiro? Bvunza kusimba simulation mishumo uye inopisa gradient matanda pane mujenya.
- Vanogona here kuteedzera batch yega yega kune yakabikwa certs-kusanganisira mill bvunzo mishumo uye spectrographic ongororo? Hapana kunze kwecobalt kana nickel alloys.
- Vanoita-in-process CMM cheki pane zvakasvibirira kana wakisi mapatani-kwete zvikamu zvekupedzisira chete? Yakakosha kune GD&T-inorema magungano senge pombi silinda dzimba.
- Ndeipi chiyero chavo chegoho chakasimbiswa pane yako chaiyo alloy uye geometry? Kwete “avhareji yeindasitiri”—yako.
- Ivo vanobatana-kuongorora manufacturability panguva yekuburitswa kweinjiniya-kwete mushure mekutanga kwekushandisa? Isu tinocherekedza njodzi senge undercuts inoteya ceramic shell material kana radii idiki zvakanyanya pamapini epakati.
Iko hakuna pasi rose "yakanakisa" simbi yekukanda nzira. Pane chete mutambo wakakodzera - wekesi yako yemutoro, zvinhu zvako, kushivirira kwako, uye hwindo rako rekuburitsa repasirese. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tinobata zvese zvekukandira sehurongwa-kwete chikamu. Nekuti muma hydraulic masisitimu, oiri & gasi zvishandiso, uye engineering mota drivetrains, imwechete porosity cluster haisi yekushongedza kukanganisa. Iyo inzira yekudonha. Kuneta kwakabva. Kukundikana kwemunda kwakamirira kuitika.
Sarudza maitiro anoremekedza chinangwa chechikamu chako-kwete chimiro chayo chete.
