Gravity cast iron parts zvinhu zvesimbi zvinogadzirwa nekudira simbi yakanyungudutswa muforoma pasi pesimba regiravhiti, pasina kumanikidzwa kwekunze. Iyi inodhura-inoshanda yekukanda nzira yakanakira kugadzira akaomesesa geometries ane yakanakisa mekiniki zvivakwa, zvichiita kuti ive sarudzo inosarudzika yemotokari, muchina, uye mashandisirwo ezvivakwa uko kusimba uye kugadzikana kwedimensional kwakakosha.
Chii chinonzi Gravity Cast Iron Parts?
Gravity cast iron parts inoreva zvikamu zvakagadzirwa kuburikidza negiravhiti kufa kukanda kana kugadzika mold kukanda maitiro uchishandisa iron-based alloys. Kusiyana ne-high-pressure die casting, iyi nzira inotsamira chete pasimba rinokwevera rekuzadza gomba remuvhu. Mhedzisiro ndeye dense microstructure ine shoma gasi porosity, inopa simba repamusoro kana ichienzaniswa nekukanda jecha.
Maitiro acho anowanzo sanganisira reusable metal molds, kazhinji inogadzirwa kubva kusimbi kana simbi, iyo inobvumira kushivirira kwakasimba uye kutsetseka kwepamusoro kupera. Gravity cast iron parts vanozivikanwa zvakanyanya mumainjiniya madenderedzwa kune chiyero chavo pakati pekuita basa rekugadzira uye kuvimbika kwezvinhu.
Mainjiniya vanofarira nzira iyi pavanenge vachigadzira zvinhu zvinofanirwa kumirisana nekupisa bhasikoro kana kushushikana kwemagetsi. Kusavapo kwekunetseka kuzadza kunoderedza oxide inclusions, kuve nechokwadi chekuti chigadzirwa chekupedzisira chinosangana neakaomarara indasitiri zviyero zvekuvimbika uye hupenyu hurefu.
Maitiro ekugadzira eGravity Cast Iron
Kunzwisisa mafambiro ekugadzira kwakakosha kune vatengi vanoongorora kugona kwevanopa. Iyo gravity yekukanda maitiro yakasarudzika nekuda kweiyo inodzorwa yekuzadza uye kusimba zvikamu, izvo zvinopesvedzera zvakananga kunaka kwechikamu chekupedzisira.
Nhanho-ne-Nhanho Kugadzira Kufambiswa Kwekushanda
- Kugadzirira Mold: Reusable metal molds preheated kune chaiyo tembiricha kudzivirira kupisa kutyisa uye kuve nechokwadi chekuyerera kwesimbi.
- Kunyunguduka uye Alloying: Simbi yakasvibirira inonyungudutswa muchoto, iine madhirigi chaiwo anounzwa kuti awane makemikari anodiwa.
- Kudira: Simbi yakanyungudutswa inodururwa nemaoko kana kuti otomatiki mugomba reforoma iri pasi pesimba regiravhiti.
- Solidification: Iyo simbi inotonhorera uye inoomesa mukati me mold, ichigadzira pedyo-neti chimiro chechikamu.
- Ejection uye Kuchenesa: Kana yatonhodzwa, chikamu chinobudiswa, uye magedhi kana zvikwiriso zvinobviswa kuburikidza nekugadzira kana kugaya.
- Kuongorora Kwemhando: Zvikamu zvekupedzisira zvinoongororwa mativi uye bvunzo dzisiri dzekuparadza kuti dzione kutendeseka.
Iyi nzira yakarongeka inovimbisa kuenderana mukati memaitiro makuru ekugadzira. Iyo inodzorwa yekutonhodza mwero inobvumira kuumbwa kweiyo yakanaka yezviyo chimiro, iyo yakakosha mukusimudzira ma mechanic properties ye. giravity cast iron parts.
Key Technical Parameters
Kukandira kwakabudirira kunoenderana nekuchengetedza kudzora kwakasimba pane akati wandei. Mold tembiricha, kumhanya kwekudira, uye alloy kuumbwa ndizvo zvinhu zvekutanga zvinotaridza mwero wekubudirira. Kutsauswa mune aya ma parameter kunogona kutungamirira kune hurema hwakadai sechando kuvhara kana misruns.
Vashandi veindasitiri vanosimbisa kukosha kwehunyanzvi hwekuputira mold. Aya machira anochengetedza mold pamusoro uye anogadzirisa kupisa kupisa, achiwedzera kunatsa iyo microstructure yekukanda. Kutarisira kwakaringana kwezvinhu izvi zvehunyanzvi kunosiyanisa vagadziri vemhando yepamusoro kubva kune avhareji vatengesi.
Mhando dzeIron Alloys Anoshandiswa muGravity Casting
Kusarudza alloy yakarurama kwakakosha pakuita kwechikamu chekupedzisira. Akasiyana masimbi alloys anopa akasiyana mazinga esimba, ductility, uye kupfeka kuramba, akagadzirirwa kune chaiyo application zvinodiwa.
Grey Cast Iron
Grey cast iron ndiyo inonyanya kushandiswa mukukanda giravhiti nekuda kwekunaka kwayo kukanda uye vibration kunyorova maitiro. Kuvapo kwema graphite flakes kunopa self-lubricating properties, zvichiita kuti zvive zvakanaka kune injini mabhuroko uye mabhureki discs.
Kunyange iine simba rakadzika rekusimba kana ichienzaniswa nemamwe alloys, simba rayo rekumanikidza rakasiyana. Mainjiniya anowanzo tsanangura gireyi simbi yemashandisirwo uko kuomarara uye kupisa conductivity kwakanyanya kukosha pane kupikisa kuramba.
Ductile (Nodular) Iron
Ductile iron, inozivikanwawo se nodular iron, ine spheroidal graphite zvimiro zvinovandudza zvakanyanya kuoma uye kureba. Izvi zvinoita giravity cast iron parts yakagadzirwa kubva kune ductile iron yakakodzera kune inorema-basa kunyorera senge crankshafts uye gearboxes.
Kugadziriswa kwechimiro chegirafu panguva yekunyunguduka kunowedzera kugona kwechinhu kutora simba pasina kutsemuka. Inovhara mukaha pakati pekukandwa kwegireyi iron uye michina yesimbi.
Iron inogoneka
Simbi inogadzika inogadzirwa nekupisa-inobata simbi chena yakakandwa kushandura kabhoni kuita hasha kabhoni node. Iyi nzira inoburitsa chinhu chine yakanaka ductility uye machinability, anowanzo shandiswa kune zvidiki, zvakaomarara zvigadziriso uye zvekurima zvekushandisa.
Kunyangwe kutenderera kwekugadzira kwakareba nekuda kweiyo annealing nhanho, izvo zvinokonzeresa zvivakwa zvinoruramisa iyo mari yezvikamu zvinoda kupikisa kwakanyanya muzvikamu zvitete.
Zvakanakira uye Zvakaipa Kuongorora
Kuongorora zvakanakira nezvayakaipira kunobatsira vatengi kuita sarudzo dzine ruzivo maererano nekugoneka kweprojekiti uye kugoverwa kwebhajeti. Gravity casting inopa yakasarudzika seti yemabhenefiti asi zvakare inopa zvimwe zvipimo zvichienzaniswa nedzimwe nzira dzekugadzira.
| Feature | Zvakanakira | Zvakaipa |
