Vanhu vazhinji pavanonzwa 'makambani ekukanda jecha', vanofananidzira uriri hwakasvibira, hune huruva, huchingodurura simbi muzviumbwa zvejecha. Ndiwo mufananidzo wekare, asi ingori 20% yenyaya nhasi. Dambudziko chairo, uye uko mapurojekiti mazhinji anokanganiswa, hakusi kuzvikanda-ndizvo zvese zvinoitika simbi isati yarova jecha uye mushure mekunge yatonhora. Ndiyo mhinduro yedhizaini, kugadzira patani, iyo post-casting machining, uye zvinhu zvesainzi kuseri kwayo. Kana iwe uri kungotenga kukanda, iwe unenge uchisiya kukosha-uye kuvimbika-patafura.
Iyo Core Misconception: Ingori Chigadzirwa
Zvikwata zvakawanda zvekutenga zvinhu zvinobata jecha rekukanda sekutenga kuri nyore. Tumira dhirowa, tora quote, tora yakachipa, mirira zvikamu. Nzira iyoyo ndiyo nzira yekurapa misoro. Maitiro ekukanda jecha anoshamisa, asi kuti kuita zvakasiyana-siyana zvinoreva kuti mhedzisiro inotsamira zvakanyanya pahunyanzvi hwevakatanga. Saizi yejecha rezviyo, binder system (jecha regirini rinopesana neresin-bonded, semuenzaniso), dhizaini yekugezera — izvi hazvisi zvidiki. Ivo vanoraira zvimiro zvemuchina, kupera kwepamusoro, uye mukana wekukanganisa kwakavanzika senge shrinkage porosity.
Ndakaona zvikamu zvakagadzirirwa zvakanaka zvichitadza mukuyedza nekuti iyo yakasarudzika yakasarudzwa zvichienderana nemutengo yakashandisa isina kufanira jecha system yejiometry, zvichitungamira kusingawirirane kutonhora. Kudhirowa kwacho kwaida imwe giredhi re ductile iron, uye chemistry report yaienderana, asi microstructure yaive yakashata nekuti mwero wekutonhora muforoma wanga usina kunaka. Muvambi wacho akaita chaizvo izvo zvaive padhinda, asi kudhinda hakuna-uye hakwaigona-kutsanangura maitiro ekutanga. Ndiyo mukaha.
Apa ndipo panozvisiyanisa vatambi vagara kwenguva refu. Hazvisi zvekuva nemavira makuru; ndezvekuva nemetallurgical uye process engineering in-house kutungamira dhizaini. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), somuenzaniso, nemakore avo 30 okugadzira nokugadzira, sezvingabvira vane zivo iyoyo yakadzika midzi. Unogona kuvawana panzvimbo yavo, tsngtaocnc.com. Chinangwa chavo hachisi chekungogadzira mold; zvakanyorwa ipapo: zvinosanganiswa shell mold casting uye Investment casting unyanzvi ne CNC machining. Icho chiratidzo chekuti vari kufunga nezve yese yekugadzira cheni, kwete yekutanga nhanho.
Iyo Yakakosha Link: Kubva Kukanda kuenda kuMachining
Uyu ndiwo mutyairi wemutengo usingatarisirwi zvakanyanya. Kukandwa kwejecha kunobuda nemakona ekudhirowa, mitsara yekuparadzanisa, uye zvinhu zvakawandisa (gedhi uye sisitimu yekusimudza). Kuchigadzira kusvika kumagumo ekupedzisira kunopihwa. Asi kana mupi wekukanda uye shopu yemuchina ari masangano akaparadzana, unowana mutambo wekupomera. Iye machinist anowana nzvimbo yakaoma kana yepasi pevhu isina chinhu, uye iko kurwira kuti imhosva yani-yekutanga yekukanda kwakashata kana machinist yekutora zvakanyanya kuchekwa.
Integrated suppliers, avo chokwadi makambani ekukanda jecha izvo zvinobatawo machining, bvisa izvozvo. Ndivo varidzi vehurongwa hwese kubva kusimbi yakanyungudutswa kusvika pachikamu chapera. PaQSY, vanotaura zvakajeka kushanda nesimbi yakakandwa, simbi, isina tsvina, uye alloys akakosha senge cobalt uye nickel-based. Kugadzira izvi, kunyanya ma superalloys, ishasha pachayo. Kuve nekukandira uye machining pasi pedenga remba kunoreva kuti vanogona kukwidziridza dhizaini yekukandira-pamwe vachiwedzera imwe pfuma munzvimbo ine hunyanzvi vachiziva yavo CNC dhipatimendi ichazvibata. Ivo vakatove vakakonzeresa mukukanganiswa kubva mukupisa kurapwa kusati kwaitwa kwekutanga kucheka. Hazvina musono.
Ndinoyeuka purojekiti yemuviri wevharuvhu mustainless 316. Masampuli ekutanga kubva kune foundry-chete mutengesi akagadzirwa zvisina kunaka, ane chatter chatter uye kukurumidza kuisa kupfeka. Takaunza dambudziko kune akabatanidzwa mupi. Mhinduro yavo yaive yakapusa: vakagadzirisa zvimbi zvekutonhodza muforoma zvishoma kuti vashandure kusimba kwekutevedzana, zvichikonzera kuomarara kwakafanana munzvimbo dzinofanirwa kugadzirwa. Dhirowa haina kuchinja, asi chikamu chekukandwa chaive chakanyanya kugoneka. Iro rudzi rwekugadzirisa chete rinouya kubva pakudzora ese ari maviri maitiro.
Kusarudzwa Kwezvinhu Haisi Ingori Menyu yekudonha
Vatengi vanowanzouya vachiti, ndinoida musimbi isina tsvina. Zvakanaka, asi ndeipi? 304 ye general corrosion? 316 yemakloridi? Kana CF8M yakakandwa yakaenzana? Uye ndezvekuremerwa kwemutoro here kana kungochengeterwa mvura? Sarudzo inobata zvakananga kukanda kwejecha. Austenitic stainlesses ine yakakwira shrinkage rates-inoda yakasimba kusimuka masisitimu akagadzirwa nemunhu anoziva iyo chaiyo alloy maitiro.
Apa ndipo panotaurwa nezve alloys akakosha paprofile yekambani. Kana a kambani yekukanda jecha inonyora nickel-based kana cobalt-based alloys, inondiudza kuti vangangove vari kubata nepamusoro-tembiricha kana corrosive service applications. Funga turbine zvikamu, pombi impellers kune hutsinye makemikari. Aya haasi mabasa akajairika. Kudira ma alloys aya kunoda kunyatso kudzora tembiricha, kazhinji pasi pemamiriro ekunze ekudzivirira, uye kemisitiri yejecha mold inofanirwa kuenderana kudzivirira kuita kwepasi. Iligi rakasiyana nekukanda grey iron kune counterweight.
Ndakaita chikanganiso kamwe chete, ndichisundira kune yevaridzi nickel alloy yeyakanyanya-kupisa gadziriso nekuti iyo data sheet zvivakwa zvaive zvakakwana. Handina kubvunza zvakadzama zvakakwana ne foundry kutanga. Zvakazoonekwa kuti alloy yaizivikanwa nekupisa kubvaruka muzvikamu zvakakora nejecha ravaishandisa. Isu taifanira kudzokera kumashure, chinja kune rimwe giredhi rinokandwa, uye nekugadzirisazve zvivakwa zvakasiyana zvishoma. Chidzidzo: Kusarudzwa kwezvinhu inhaurirano nemetalurgist yevakatanga, kwete sarudzo yega engineering.
Iwo Unsexy Details Anogadzira kana Kuputsa Chirongwa
Patternmaking. Ndiwo mutengo wepamberi wese anoda kudzikisira, asi ndiyo hwaro hwezvese. Patani yemapuranga yakachipa, yakamonyoroka inoburitsa mold isingawirirane zvachose. Pakumhanya kwekugadzira, iyo mari mune yakasimba, ine dimensionally yakagadzikana simbi pateni (kazhinji aruminiyamu kana simbi) haigone kutaurirana. Zvakanaka makambani ekukanda jecha zvichava pamusoro peizvi. Vanogona kutotarisira kugadzirira iwe, inova bhenefiti huru.
Zvadaro pane zvinyorwa zvemhando. Yekutengesa-giredhi yekukanda inogona kungowana kuongororwa kwekuona. Chinhu chakakosha chinoda zvinhu cert (mill test report), pamwe radiographic kana ultrasonic bvunzo yekunzwika kwemukati, uye yekutanga-chinyorwa chekuongorora mishumo. Iwe unofanirwa kuziva kuti ndeipi nhanho yaunoda uye simbisa kugona kwemutengesi kunoenderana. Chitoro chinoita zvakare machining chaiwo chinowanzo gadzirirwa nhanho iyi yezvinyorwa, sezvazviri mukugadzira zvitoro zvebasa.
Nguva yokutungamira ndechimwe chipingamupinyi chinoshanda. Vanhu vanofunga kuti kukanda jecha kunokurumidza nekuti inzira iri nyore. Kugadzira chimiro chitsva, kukodzera zvinyorwa zvekutanga, kugadzira mitsetse yekuumba-inotora nguva. Kudira chaiko kunokurumidza. Kurongeka kwechokwadi kubva kune nyanzvi yekugovera account kune ese matanho aya. Chivimbiso chemavhiki maviri ekutungamirira nguva yechikamu chitsva, chakaoma chinowanzova mureza mutsvuku.
Kutarisa Kushanda Kwenyika Yechokwadi
Ngatitendererei kumuenzaniso uya we Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Kugona kwavo kwakanyorwa pa tsngtaocnc.com penda mufananidzo weimwe mhando yekushanda. Vanotaura shell mold casting, inova nhanho pamusoro peyakajairwa jecha regirinhi maererano nedimensional kurongeka uye kupera kwepamusoro. Inowanzoshandiswa kune yepakati-vhoriyamu, yakawanda yakaoma zvikamu. Kubatanidza izvozvo Investment casting (nokuda kwepamusoro nemazvo) uye yakazara CNC machining inoratidza kuti vari kunanga chikamu chemusika chinoda kugadzirira-ku-kuisa zvikamu, kwete rough castings.
Rudzi rwazvo rwezvinhu - kubva kune akajairwa simbi uye simbi kusvika kune ekunze alloys - inoratidza inochinjika yekunyunguduka setup, pamwe masimbi ekupinza anogona kuchinja pakati pealloys nekucheneswa kwakakodzera. Kune mutengi, ichi ndicho chinhu chinokosha. Zvinoreva kuti kana prototype yako ikatanga mucarbon simbi asi ichida kutamira kune tsvina yekuora, ungasazofanira kutsvaga mutengesi. Vanogona kubata iyo shanduko, vachinzwisisa akasiyana maitiro ekukanda.
Iyo yekutora kana uchiongorora chero kambani yekukanda jecha ndiko kutsvaga rudzi urwu rwekubatanidza kwakatwasuka uye hupamhi hwezvinhu. Haisi vimbiso yekukwana, asi chiratidzo chakasimba chavanonzwisisa hupenyu hwakazara hwechikamu. Ivo vangangove vakagadzirisa matambudziko ekumisikidza pakati pekukanda uye machining, uye vangangove vakabata nemusoro wekupihwa zvitupa. Mundima iyi, iyo yakaunganidzwa, inoshanda yekugadzirisa matambudziko-rudzi rwunouya kubva kumakore makumi matatu ekushanda-ndiyo yakakosha pfuma ivo, uye iwe semutengi, unogona kuva nayo. Inoshandura kutenga kuri nyore kwekukanda kuita mubatanidzwa wekugadzira.
