Kana mainjiniya ataura zvinoumba simbi isina tsvina pamavharuvhu ehydraulic, pombi dzepombi, kana mawinch shafts—zvikamu zvinofanirwa kurarama 300+ bar pressure, abrasive slurry flow, kana cyclic thermal stress—havawanzobvunza kuti “Ndeipi nzira yekukandira yandinofanira kushandisa?” Vanobvunza kuti: "Chikamu ichi chichaita kushivirira ± 0.02 mm * uye * kuramba kuparara kwegomba mubasa remvura yegungwa * uye * ngarava mumavhiki matanhatu?" Apa ndipo pane chokwadi yakarasika wakisi inokanda simbi isina tsvina fekitari inowana nzvimbo yayo-kwete semutengesi, asi sekuwedzera kwekugadzira.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshandisa imwe nzvimbo yakadaro muQingdao. Takakanda AISI 316L mavharuvhu miviri yeNorth Sea subsea control modules apo imwe chete microporosity defect inogona kukonzera kurambwa kuzere. Isu takagadzira AMS 5387 cobalt alloy nozzles yeakakwira-kumanikidza mafuta jekiseni pombi-zvinhu zvakawoma zvekuti inopfeka maturusi ecarbide nekukurumidza kupfuura zvaitarisirwa-uye akaendesa-yekutanga-chinyorwa zvikamu zvine CMM-yakasimbiswa madziro kusiana pasi pe0.015 mm. Uku hakusi kugona kwe theoretical. Iyo inodzokororwa kuuraya mukati me127 kugadzirwa inomhanya gore rapfuura chete.
Zvinhu zvitatu zvehunyanzvi zvinopatsanura kurongeka kwakarasika kubva kuzvitoro zve "investment casting" - uye nei zvichikosha kuchirongwa chako chenguva uye kuvimbika kwemunda:
- Material traceability inotanga pamberi pe mold: Isu tinopa ingots yesimbi isina tsvina yakasimbiswa kuASTM A743/A744 Giredhi CF8M uye EN 1.4408-ine yakazara kupisa zvitupa, spectrographic mishumo yekuongorora, uye intergranular corrosion bvunzo mhinduro dzakachengetwa pane imwe yakawanda. Hapana batch inotsiva. Hapana "yakaenzana giredhi" inotsiva pasina kusaina kweinjiniya.
- Dimensional control inogara mune iyo pateni, kwete iyo yekuongorora report: Yedu mapatani ewakisi ndeye CNC-yakagadzirwa kubva yakasimba POM, kwete 3D-yakadhindwa resin. Sei? Nekuti POM inobata ± 0.01 mm pamusoro pe200 mm pa22 ° C ambient - uye inoderera zvinofanofungidzira panguva yekudonha. Mapatani akadhindwa anokanganisa zvisingatarisike pamusoro pe150 mm. Isu tinosimbisa pateni yega yega neoptical contour scanning *pamberi* chivakwa chegomba chatanga.
- Kutendeseka kwepamusoro hakugone kutaurirana kune kushanda chisimbiso: Chigaro chevhavha yekumanikidza haina kupukutwa kuti itaridzike. Yakadzika kusvika kuRa ≤0.4 µm * mushure me* kurapwa kwekupisa-nekuti kusara kwekunetsekana muas-cast surface layer kunokonzeresa kutsemuka pasi pemutoro wecyclic. Isu tinobatanidza mhinduro annealing (1050 ° C + kudzima mvura) uye kunetseka-kuzorodza kugaya kuita imwe inodzorwa kutevedzana. Kwete maoperation maviri akasiyana.
Vamwe vanogona kupokana kukanda jecha kunowana mutengo wakafanana wezvikamu zvakakura zvisina tsvina. Asi kana imba yako yepiston pombi silinda inoda machani ekutonhodza emukati ane 3.2 mm mudhuri ukobvu, concentricity iri pasi pe0.05 mm kuyambuka 320 mm kureba, uye zero yemukati shrink cavities - kukanda jecha kunotadza. Wakisi yakarasika inouendesa. Isu takayera goho risina mhango pa94.7% yedzimba dziri pasi pe12 kg, maringe ne61% yemhando dzakafanana nejecha-cast-cast mubenchmarking yedu yemukati. Musiyano wacho? Shell mold permeability control, chaiyo preheat ramp rates, uye vacuum-yakabatsira kudurura-zvese zvakagadziriswa pagiredhi alloy uye ukobvu hwechikamu.
Izvi zvinorevei kune yako sarudzo yekutenga? Kutanga, kutungamira nguva yekumanikidza. Kufamba kwedu kwakaonda kunobatanidza GD&T ongororo *panguva* wax pateni hurongwa-kwete mushure mekushandisa kuvakwa. Isu tinocherekedza zvingangoitika kudhirowa nyaya, sink mamaki, kana kukanganiswa kwegedhi pa STEP faira rako mukati memaawa makumi mana nemasere. Chechipiri, kuderedza ngozi. Yese yakakandwa simbi isina tsvina inopinda 100% MPI (magnetic particle inspection) * uye * ultrasonic bvunzo ye subsurface kukanganisa. Chechitatu, scalability. Isu tinomhanyisa mitsara yekuvaka-yakafanana-imwe yekukurumidza-kutendeuka prototypes (7-10 mazuva), imwe yepakati-vhoriyamu maodha (50-500 pcs) ine yakagadziriswa yechoto kutenderera uye yakagovaniswa post-cast kupisa kupisa mabhechi. Hapana requalification inodiwa pakati pemijenya.
Tarisa kumberi: Muganhu unotevera hausi kungoshivirira kwakasimba - kugadzirwa kwakasanganiswa. Isu zvino takamisikidza machina ekutsvaga maficha zvakananga muinvestment casting pattern. Nheyo yepombi inosvika nemakomba ayo anokwirisa, dowel pin bores, uye yekuisa chisimbiso yatopera CNC-kuderedza sekondari ops ne68%. Kune T800 cobalt-based superalloys, isu tinosanganisa kusimba kwekutungamira panguva yekukanda ne cryogenic machining kuchengetedza chimiro chezviyo. Aya haasi maR&D concepts. Vari kumhanya mukugadzira matatu eEuropean OEMs nhasi.
Kana iwe uchida zvinhu zvesimbi zvisina simbi uko kutadza kusiri sarudzo - uye uko "chaizvo" zvinoreva kuyerwa, kudzokororwa, kuita kwakanyorwa - wobva wabatana ne yakarasika wakisi inokanda simbi isina tsvina fekitari iyo inobata simbi sefizikisi, kwete ngano, inoshandura zvese. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. haisi kungokanda simbi. Inosimbisa basa.
