Ukanzwa 'mhete yevharuvhu', vazhinji vanofunga nezvechikamu chiri nyore chekuisa chisimbiso. Ndiyo yekutanga kusanzwisisa. Muchokwadi, a vharafu mhete chimiro chakakosha, chikamu chekupfeka chinoraira hupenyu hwebasa uye kuvimbika kwehurongwa. Hazvisi zvekungobata pressure; ndezvekutonga kukwesha, kutenderera kwemafuta, uye kuenderana kwezvinhu pasi pemitoro ine simba. Ndakaona mapurojekiti akawandisa apo mhete yaive yekufungidzira, zvichikonzera kukundikana nguva isati yakwana. Chokwadi ndechekuti, kuita kwayo kunowanzo kuve bhodhoro regungano rese revharuvhu.
Iyo Material Conundrum: Haisi Kungori Simbi
Kutsanangura zvinyorwa zve a vharafu mhete ndipo panosangana dzidziso nemuguyo. Chaizvoizvo. Kushevedzera kwegeneric kwesimbi isina tsvina ndiyo nzira yedambudziko. Iri kushanda munzvimbo ine gasi rakavava here? Iwe unogona kunge wakatarisa super duplex kana nickel-based alloy seInconel 625. Ringi haisi kungogara ipapo; inogara ichibatanidza uye isingabatanidzi. Isu takanga tine nyaya yemutengi muchikamu chemakemikari umo yakajairwa 316L mhete dzakaora uye dzakaputika mukati memwedzi. Ongororo yekutadza yakaratidza chloride-induced stress corrosion cracking. Mhinduro yakanga isiri kungochinja giredhi; yakanga iri shanduko mune yese nzira yekugadzira.
Apa ndipo panobva pava neruzivo rwakadzama rwezvinhu. Ndakashanda nevashambadziri vakaita Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) pamatambudziko akafanana. Makumi matatu avo ekukanda alloys akakosha haisi nzvimbo yekutengesa chete. Nokuda kwepurojekiti yepamusoro-soro yevhavhavha, taida zvindori mu cobalt-based alloy (Stellite 6) yekupfeka zvakanyanya uye kudzivirira kupisa. Dambudziko rakanga risiri kungorikanda; yaive ichiwana homogeneous microstructure kudzivirira kupaza panguva yaitevera CNC machining. Chiitiko cheQSY negoko rekuumbwa uye kukanda mari kune alloys akadaro zvaireva kuti vaigona kuraira pane yakakwana pre-kupisa tembiricha uye gating system dhizaini kuderedza kushushikana kwemukati kubva pakutanga. Irwo ruzivo runoshanda, rwemaitiro-chikamu ndicho chinoparadzanisa mupi wezvikamu kubva kune wekugadzira shamwari.
Sarudzo pakati pemitoo yekukandira inobata zvakananga zvimiro zvekupedzisira zvering. Kune yakaoma geometries kana yepamusoro yepamusoro kupedzisa, kuisa mari kukanda mambo. Asi kune mamwe akakwira-vhoriyamu, akareruka profiles, yakanyatso itwa ganda mold casting inogona kupa iri nani mutengo-kuita reshiyo. Chinokosha kunzwisisa kutengeserana-offs: kukanda mari kunogona kukupa chimiro chepedyo-neti chinoda kushoma machining, asi kune dzimwe mhuri dzealloy, chimiro chezviyo chakatsetseka kubva kugoko regoko chingave chiri nani pakuoma kwekupedzisira. Hapana mhinduro yepasi rose.
Precision iMaitirwo, Kwete Danho
Iwe haugoni kukanda zvakakwana vharafu mhete yakagadzirira kuiswa. The as-cast part inongova isina chinhu. Iwo mashiripiti chaiwo — uye uko kukundika kwakanyanya kunoitika — kuri mukugadzira. Kushivirira kwemhete grooves, kutaridzika kwechiso, uye kupera kwepamusoro (kazhinji Ra 0.4 kana zvirinani) zvine hutsinye. Ndinoyeuka batch apo marin'i akapfuura macheki emativi asi achikonzera kubuda. Nyaya yacho? Micrometer-level waviness pachiso chekuisa chisimbiso icho chisina kubatwa neyakajairwa Ra kuyerwa. Zvaida profilometer uye machinist ainzwisisa kuti kupera kwekupedzisira kunoda imwe nzira yekushandisa uye kuoma.
Izvi zvinosimbisa kukosha kwekugadzirwa kwakabatanidzwa. Kuve nekukanda uye CNC machining pasi pedenga remba, sezvinoita QSY, inobvisa yakakura yengozi. Iwo machinist ipapo anoshanda nekukandira ivo pachavo vanogadzira foundry. Ivo vanoziva maitiro chaiwo ehunhu, mukana wenzvimbo dzakaoma, uye iwo akanakisa mafidhi uye nekumhanya.
