Chii chinonzi kufa casting
Die casting inzira yekugadzira inoshandiswa kugadzira simbi zvikamu zvine huremu hwepamusoro uye kupera kwepamusoro.Zvinosanganisira kumanikidza simbi yakanyungudutswa mugomba rekuumbwa pasi pekumanikidzwa kwakanyanya.Iyo mold mhango inogadzirwa nesimbi mbiri dzakaomeswa dzinofa dzakagadzirwa mune inodiwa chimiro.
Maitiro anotanga nekunyunguduka kwesimbi, kazhinji aruminiyamu, zingi, kana magnesium, muchoto.Simbi yakanyungudutswa inobva yapinzwa muforoma pahigh pressure uchishandisa hydraulic press.Simbi inokurumidza kusimba mukati me mold, uye mahafu maviri emuumbi anovhurwa kuti abudise chikamu chakapedzwa.
Die casting inoshandiswa zvakanyanya kugadzira zvikamu zvine maumbirwo akaomarara uye madziro matete, senge mabhuroko einjini, kutapurirana dzimba, uye akasiyana emotokari uye aerospace zvikamu.Maitiro aya anozivikanwa zvakare mukugadzirwa kwezvinhu zvevatengi, sematoyi, kitchenware, uye zvemagetsi.
Pressure Die Casting
Die casting inzira yakasarudzika yakagadziridzwa zvakanyanya mukati mezana ramakore rechi20.Maitiro ekutanga anosanganisira: simbi yakanyungudutswa inodirwa/inoiswa muforoma yesimbi uye kuburikidza nehigh velocity, inogara ichiwedzera uye inosimbisa dzvinyiriro (mukudzvanya kufa) uye kutonhodza simbi yakanyungudutswa inoomesa kuita kukanda kwakasimba.Kazhinji, maitiro acho pachawo anotora masekondi mashoma uye inzira yekukurumidza yekugadzira simbi chigadzirwa kubva pambishi.Die casting inokodzera zvinhu zvakaita serata, lead, zingi, aluminium, magnesium kune alloys yemhangura uye kunyange maaloyi esimbi sesimbi isina tsvina.Iwo makuru alloys anoshandiswa nhasi mukumanikidza kufa casting ialuminium, zinc uye magnesium.Kubva pamichina yekutanga kufa yakamisikidza maturusi ekufa mune yakatwasuka kusvika kune yakajairika chiyero cheyakatwasuka yekutarisa uye kushanda, ina tie bar tensioning uye yakazara komputa inodzorwa nhanho maitiro maitiro akaenderera mberi mumakore ese.
Indasitiri yakura kuita muchina wepasi rose wekugadzira, uchigadzira zvikamu zvezvakasiyana-siyana zvekushandisa, zvakawanda zvacho zvichange zvichisvika kubva kune wega sezvo chigadzirwa chekushandisa chekufa castings chakasiyana.
Benefits of pressure die casting
Mamwe mabhenefiti eiyo high pressure die casting:
• Nzira yacho inokodzera kugadzirwa kwepamusoro.
• Gadzira zviumbwa zvakaoma kunzwisisa nekukasira zvichienzaniswa nedzimwe nzira dzekugadzira simbi (eg. machining).
• Zvikamu zvesimba zvakakura zvinogadzirwa muas cast condition (zvichienderana nechikamu chekugadzira).
• Dimensional repeatability.
• Zvikamu zvitete zvemadziro zvinogoneka (semuenzaniso. 1-2.5mm).
• Kushivirira kwakanaka kwemutsara (semuenzaniso. 2mm/m).
• Kupera kwakanaka kwepamusoro (eg. 0.5-3 µm).
Iyo nzira yekupisa yekamuri yekumanikidza kufa yekukanda inosanganisira kunyungudutswa kwesimbi ingot mukati mevira iyo iri padyo/yakabatana kune yakagadziriswa hafu platen yemuchina wekukanda kufa uye jekiseni resimbi yakanyungudutswa kuburikidza neinonyura pasi pemvura yakananga kuburikidza negooseneck uye muromo uye mukati. mudziyo wekufa.Iyo gooseneck uye nozzle inoda kudziyisa kudzivirira simbi kutonhora isati yasvika pakufa, iyo yese yekudziya uye yakanyungudutswa yesimbi chinhu chechiitiko ichi ndipo panobva zita rinopisa imba.Huremu hwekukanda huremu hunotaridzwa nekurohwa, kureba uye dhayamita yeplunger pamwe nesaizi yesleeve / kamuri uye muromo unotambawo chikamu chinofanira kutariswa pane kufa dhizaini.Kana simbi ichinge yasimba mugomba rekufa (inotora masekonzi mashoma) iyo inofambisa hafu platen yemuchina iyo iyo inofambisa hafu yefa inogadziriswa kuti ivhure uye kukanda kunoburitswa kubva pachiso chefa uye kubviswa pachishandiswa.Zviso zvekufa zvinozoiswa mafuta kuburikidza nespray system, iyo inofa inovhara uye maitiro anotenderera zvakare.
Nekuda kweiyi "yakavharwa" simbi inonyunguduka / jekiseni sisitimu uye kushoma mechini kufamba inopisa kamuri yekukanda kufa inogona kupa hupfumi huri nani hwekugadzira.Zinc simbi alloy inonyanya kushandiswa mukupisa kamuri yekumanikidza kufa yekukanda iyo ine yakanyatso kunyungudika nzvimbo iyo inopa mamwe mabhenefiti ekupfeka akaderera pamakina (poto, gooseneck, sleeve, plunger, nozzle) uye zvakare yakaderera kupfeka pamaturusi ekufa (kurebesa chishandiso. hupenyu hunofananidzwa nealuminium die casting maturusi - zvichienderana nekukanda kugamuchirwa kwemhando).
Iro zita rekuti cold room rinobva mukuitwa kwesimbi yakanyungudutswa ichidirwa mukamuri inotonhora/pfuti sleeve inonamirwa nepakati yakagadzika hafu yefa platen kuseri kweyakagadziriswa half die tool.Simbi yakanyungudutswa inobata/mavira ekunyunguduka anowanzo kuwanikwa padyo nepanoperera pfuti yemuchina wekukanda kufa kuitira kuti anoshanda nemanyorero kana otomatiki yekudira ladle akwanise kuburitsa simbi yakanyungudutswa inodiwa papfuti yega yega / kutenderera neladhi uye odira iyo. simbi yakanyungudutswa ichipinda mugomba rekudira mukati meruoko/mukamuri yekupfura.Plunger tip (inove chikamu chinopfekwa uye chinotsiviwa, chakanyatsogadzirwa kune pfuti sleeve yemukati dhayamita nemvumo yekuwedzera kupisa) yakabatana negondohwe remuchina inosaidzira simbi yakanyungudutswa nemukamuri yekupfura uye mugomba rekufa.Muchina wekukanda kufa kana wakurudzirwa unoitisa nhanho yekutanga kusunda simbi yakanyunguduka kupfuura gomba rekudira muruoko.Mamwe matanho anoitika pasi pekuwedzera kwe hydraulic pressure kubva kugondohwe kuti ibaye simbi yakanyungudutswa mugomba rekufa.Maitiro ese anotora masekonzi, kukurumidza uye kuwedzera kudzvanywa pamwe nekudonha kwekushisa kwesimbi kunoita kuti simbi iome mugomba rekufa.Iyo inofamba hafu platen yemuchina wekukanda kufa inovhura (iyo iyo hafu inofamba yemudziyo wemudziyo wakamisikidzwa) uye inoburitsa iyo yakaomeswa yekukanda kunze kwekufa kumeso kwemudziyo.Iyo yekukanda inobviswa, zviso zvekufa zvinozorwa nespray system uyezve kutenderera kunodzokororwa.
Cold chamber machines inokodzera aluminium die casting, zvikamu pamushini (pfuti sleeve, plunger tip) inogona kutsiviwa nekufamba kwenguva, maoko anogona kugadzirwa nesimbi kuti awedzere kusimba.Aluminium alloy inonyungudutswa muceramic crucible nekuda kwealuminium yakakwira kunyungudika nzvimbo uye kukosha kwekudzikisa njodzi yepickup yesimbi inova njodzi mukati meferrous crucibles.Nekuti aruminiyamu isimbi yakareruka inoita kuti pave nekukandwa kweakakura uye anorema ekufa castings kana uko kwakawedzera simba uye kureruka mukufa castings kunodiwa.
