Paunonzwa 'investment casting for engineering machines,' mufananidzo uripo unogona kunge uri wepristine, yakaoma turbine mablades emuchadenga. Ndiko kushamwaridzana kwakajairika, kunenge kutarisisa. Asi mune yakasviba-pasi pezvigunwe nyika yepasi, vanochera, uye inorema-basa gearboxes, iko kushandiswa kune grittier, kushivirira kunotaurirana zvakasiyana, uye mutengo-kudzvanywa hauregi. Hazvisi zvekuwana kukwana kwedzidziso; ndezvekupa chikamu chinopukunyuka mutoro wematani makumi maviri mugomba rematope kwemaawa gumi pasina kukundikana. Musiyano iwoyo ndizvo zvese.
Kukwezva Kwakashata Kwekuoma kunzwisisa
Vatengi vanowanzouya vakagadziriswa pane geometry. Tarisa iyi chiteshi chemukati, ivo vanodaro, vachinongedza kune yeCAD modhi. Uye hongu, kukanda kwekudyara kunokunda pane izvozvo. Asi kune boom ruoko yekubatanidza kana hydraulic valve body, kukosha chaiko hakusi kuumba zvisingaite. Kutendeseka kwezvinhu pasi pesimba uye kuneta. Ndakaona maitiro akaomesesa ewakisi achiturikira kuita zvekukanda izvo zvakatadza mukuedzwa kwemumunda nekuti kusarudzwa kwealloy kwakatorwa sekufunga kwakatevera. Nzira yacho inotanga nezvinhu, kwete mold. Makambani anowana izvi, senge Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), iva nehupenyu hurefu hwekuzviratidzira. Makore makumi matatu mune iyi niche zvinoreva kuti vaona izvo alloys inoshanda kupi. Pfungwa dzavo pa special alloys-nickel-based for corrosion in slurry pumps, cobalt-based for wear faces in crusher parts-chiratidzo chechiitiko chinoshanda, kwete bhurocha chete.
Pane fungidziro inoramba iripo yekuti kuisa mari pakudyara inzira yekupedza. Hazvisizvo. Kunyanya kune zvikamu zvemichina. Iyo as-cast surface inogona kunge yakanaka, asi nzvimbo yekubatanidza ye-high-pressure chisimbiso? Never. Ndiko uko kuwirirana neCNC machining kunova kusingagone kutaurirana. Hatisi kungoita zvekukandira; tiri kugadzira pedo-net-shape preform yeakakosha machining. Ini ndinorangarira chirongwa che compact planetary gear carrier. Iyo yekukandira yakawana iyo yemukati splines uye inochengetedza huremu homwe, asi iyo flange face yaida 0.05mm flatness kushivirira. Iyo yakawanikwa iyo yaibata machining sedambudziko remumwe munhu yakakonzera hope dzehusiku hwekurongeka. Chitoro chinosanganisa machining kuronga mune yekutanga kukanda dhizaini, inova nzira yakabatanidzwa yaunoona pakuvhiya seQSY (saiti yavo pa. tsngtaocnc.com zvinonyatsobatanidza kukanda uye kugadzira), inochengetedza mwedzi yemusoro. Ipfungwa dzakasiyana.
Iko Shell Mold Inoita Kumira Kwayo (Uye Kwaisingaite)
Izvi zvinotungamira kune gakava risingaperi mune inorema michina yekugovera cheni: shell mold casting vs. investment casting. Haisi hurongwa huri nyore. Kune hombe, yakapfava, ine madziro ane makobvu, mold imambo-nekukurumidza, isingadhuri. Asi iyo nguva yaunenge uine emukati macores, matete madziro ari padhuze neakakora zvikamu, kana anoda yepamusoro metallurgical zviyo chimiro, kukanda mari kunodhonza kumberi. Iyo ceramic shell mukati Investment casting inobvumira ruzivo rwakanyanya uye zvirinani kutonhora kutonga.
Muenzaniso wekongiri: pfeka mahwendefa emusoro wedombo. Shell mold yaigona kuigadzira, asi kuenderana kwekuoma uye kupinza kwemagoro akaomarara kwaigara kuri kubheja. Kuchinjira kukudyara kwekudyara kwezvikamu zvakakosha zvekupfeka zvakatipa fungidziro, yunifomu yezvinhu zvivakwa. Mutengo wepa-chikamu chaive chakakwira, asi kudzikiswa kwekutadza kwemunda uye kuderera kwemushandisi wekupedzisira kwakagadzira kuchengetedza. Ndiyo maverengero ane basa. Zviri pamusoro pemutengo wakakwana wevaridzi, kwete chete chidimbu mutengo. Apa ndipo panoedzwa ruzivo rwemutengesi-vanogona here kukutungamirira kune nzira chaiyo, kunyange isiri iyo inotanga kudhura?
Dhiyabhorosi mune Details: Gating, Shrinkage, uye Chokwadi
Madhizaini egating emabhuku haabatsiri. Kune yakakwira-kushushikana pivot poindi pane yekuchera, haungodyisa simbi; iwe unonangisa kusimba kuti ugadzire inonzwika tsanga inoyerera munzira dzekutakura. Takadzidza izvi nenzira yakaoma pachikwata chezvombo zvakarembera. Kukandwa kwakanaka, kwakapfuura X-ray. Asi mukuyedzwa kwekuneta, vakatsemuka pane imwe nzvimbo. Ongororo yekutadza yakanongedza kune diki shrinkage porosity cluster chaipo pakakwira kushushikana kwekushushikana. Gedhi rakanga rakanyatsokodzera kuti rizadzwe, asi rakashata kuhupenyu hwemuchina wechikamu. Taifanira kugadzirisa zvakare mumhanyi uye riser system, tichiwedzera mutengo uye huwandu munzvimbo dzisiri dzakakosha kuti tikweve kusimba kuburikidza nenzvimbo yakaoma. Zvakashanda.
Uyu ndiwo musimboti usina kunaka webasa. Isimbi, simba remvura, uye ongororo yekushushikana zvese zvinotenderera mugomba receramic. A supplier list simbi yakakandwa uye simbi isina tsvina ichitoro chezvigadzirwa. Imwe inotaura nezvekugadzirisa kunyunguduka uye mold preheat ye duplex simbi isina tsvina kudzivirira sigma chikamu chekugadzirwa kwenzvimbo inoparadza yemigodhi chikamu-iyo mubatsiri. Nhanganyaya pfupi yeQSY inotaura nezvebasa ravo pane iyi spectrum, kubva kumagiredhi akajairika kusvika kune exotics. Rudzi urwu runoratidza kuti vaifanira kugadzirisa matambudziko aya, kwete kungodira simbi.
Kukundikana seKumanikidza Basa
Hausati wanyatsodzidza kuisa mari kumakina kusvika waona kukundikana. Chandainyanya kudzidzisa yaive seti yemapombi eheavy-duty dredge pump. Inconel 625, mashizha akaoma kunzwisisa. Vakapasa NDT yese. Mwedzi mitanhatu ndiri mumunda, kutsemuka kwakaparara. Mupari wemhosva? Residual shell material. Chidimbu checeramic core, chakavharirwa muchikamu chekutonhora chemukati chataifunga kuti chakajeka, chakagadzira nzvimbo inopisa uye chakashandura microstructure yemunharaunda panguva yekushanda. Yakava nucleation point yekutsemuka. Kugadzirisa kwanga kusiri kuongororwa; yaive yakawedzera hukasha uye yakasimbiswa leaching maitiro ekubvisa kwepakati. Zvino, kana ini ndichiongorora mutengesi, ndinobvunza nezve yavo yepakati yekubvisa mapuroteni emapofu ndima. Mhinduro inondiudza kupfuura chero chitupa chemhando.
Kubatanidzwa ndiyo chete nzira yekuenda mberi
Tichitarisa mamiriro ezvinhu izvozvi, ramangwana harizi mudzimba dzekukandira dzakazvimirira. Injiniya muchina maOEM ari kudzvanya nguva dzekutungamira uye achida izere chikamu chebasa. Iyo yakabudirira modhi yekubatanidza yakatwasuka: kugadzira pateni, kukanda, kurapwa kwekupisa, uye chaiyo machining pasi pedenga remba, kana zvishoma pasi pekubatana kwakasimba. Izvi zvinotonga zvinoshanduka. Kana iyo machinist ikawana kutsauka kudiki mukukanda, ivo vanogona nekukurumidza mhinduro kune iyo injinjiniya, uye kudira kunotevera kunogadziriswa. Kuparadzaniswa kwemabasa aya kunowedzera mavhiki uye zvidimbu zve opacity.
Ichi ndicho chikonzero muenzaniso wekambani unoda QSY zvine musoro. Yavo yakataurwa nyanzvi mune ese ari maviri shell mold casting uye Investment casting, pamwe chete CNC machining, haisi rondedzero yebasa chete. Kuziva kuti chikamu ndicho chigadzirwa chekupedzisira, kwete kukanda. Makumi matatu avo emakore angangodaro anoreva kuti vakashanduka kubva kune yakavamba kuita mupi wemhinduro, nekuti musika wakavamanikidza. Iwe haugone kurarama kwenguva yakareba kudaro uchishandira iyo engineering michina chikamu nekungogadzira yakanaka wakisi mapatani. Iwe unopona nekuona kuti chikamu chinosungirirwa pamushini hachidzoke.
Saka, kana iwe uchitsvaga, tarisa kunze kweiyo kiyi izwi. Tsvaga humbowo hwekubatanidzwa kwekugadzirisa matambudziko. Bvunza nezve hunhu hweimwe alloy mukushandisa kwakafanana. Ongorora nyaya yekukundikana uye zvakadzidzwa. Hunyanzvi chaihwo mu mari yekukandira yeinjiniya michina zvikamu yakavigwa mune izvo zvisina kunaka, ruzivo runoshanda, kure kure nezvinopenya zvivimbiso zvekushambadzira. Iri muhuremu hwekambani yemakore makumi matatu ichiri kugadzirisa, uye mukuvimba kwakanyarara kunobva pakugadzirisa zvakaputsika.
