Yini efa
I-Die Casting inqubo yokukhiqiza esetshenziselwa ukukhiqiza izingxenye zensimbi ngokunemba okuphezulu okuphezulu kanye nokuqedwa komhlaba. Kubandakanya ukuphoqa insimbi encibilikisiwe ibe yi-capity eyisikhukhula ngaphansi kwengcindezi ephezulu. I-Mild Cavity idalwe yi-wether eluhlaza eyonakalisiwe etholwa emkhakheni owufunayo.
Inqubo iqala ngokuncibilika kwensimbi, ngokujwayelekile i-aluminium, i-zinc, noma i-magnesium, esithandweni somlilo. Insimbi ebilisiwe bese ifakwa kubumba ngokucindezela okukhulu kusetshenziswa umshini we-hydraulic. Insimbi yensimbi iqinisa ngokushesha ngaphakathi kwesikhunta, futhi ama-halves amabili wesikhunta avulwa ukukhipha ingxenye ephelile.
Ukudla okufa kusetshenziswa kabanzi ukukhiqiza izingxenye ezinobukhulu obuyinkimbinkimbi kanye nezindonga ezincanyana, njengamabhulokhi enjini, izindlu ezihambisayo nezimoto ezihlukile. Le nqubo iyathandwa futhi ekukhiqizweni kwezimpahla zabathengi, njengamathoyizi, ekhishini, kanye ne-elekthronikhi.
Ingcindezi Die Casting
I-Die Casting iyinqubo ekhethekile ekhethekile eye yathuthuka kakhulu phakathi kwekhulu lama-20. Inqubo eyisisekelo iqukethe: Kuthunyelwa insimbi ebiwe kabusha / kufakwe kubumba lensimbi futhi ngengcindezi ephezulu, ihlala icindezele (ekucindezelweni kwensimbi eqinile) nokupholisa i-molate yensimbi iqinisa ukusakaza okuqinile. Imvamisa, inqubo uqobo ithatha imizuzwana embalwa futhi iyindlela esheshayo yokwakha umkhiqizo wensimbi kusuka ezintweni ezingavuthiwe. I-Die Casting ilungele izinto ezifana ne-tin, ukuhola, i-zinc, i-aluminium, i-magnesium kuya kwama-aloys angenazinsimbi. Ama-alloys asemqoka asetshenziswa namuhla ekucindezelweni kwe-die casting yi-aluminium, i-zinc ne-magnesium. Kusuka emishinini yokufa kokuqala okususwe amathuluzi okufa ngokuqondile okuthe mpo kwiZinga elijwayelekile manje elijwayelekile lokufunda okuvundlile nokusebenza, inqubo yokulawulwa kwe-tie elawulwa ngokuphelele nenqubo yenqubo eye yathuthukiswa kuyo yonke le minyaka.
Umkhakha ukhule waba ngumshini wokukhiqiza emhlabeni jikelele, wenza izakhi zezinhlelo zokusebenza ezahlukahlukene, eziningi zazo ezizofinyelela kubantu uqobo njengohlelo lokusebenza lomkhiqizo oluhlukile.
Izinzuzo zengcindezi efa
Ezinye zezinzuzo zengcindezi ephezulu yokufa okudina:
• Inqubo ilungele ukukhiqizwa kwevolumu ephezulu.
• Khiqiza ukukhonkotha okuyinkimbinkimbi ngokushesha uma kuqhathaniswa nezinye izinqubo zokwakha zensimbi (isib. Ukufakwa kwemishini).
• Izakhi zamandla aphezulu ezikhiqizwe ku-As Cast Stage (ngokuya ekwakhiweni kwengxenye).
• Ukuphindaphinda okuyisisekelo.
• Izigaba zodonga oluncanyana kungenzeka (isib. 1-2.5mm).
• Ukubekezelela okuqondile okuqondile (isib. 2mm / m).
• Ukuqedwa okuhle komhlaba (isib. 0.5-3 μm).
Inqubo yokutholwa kwengcindezi eshisayo yeChamber Tried ibandakanya ukuncibilika kwe-Ingot Ingot esithandweni somshini osusondele / umjovo we-molten wensimbi ngokuqondile nge-goosenneck ne-nozzle futhi ungene ethubeni lokufa. I-gooseneck ne-nozzle idinga ukufudumeza ukuvikela i-wetal iqhwa ngaphambi kokuthi ifinyelele emgodini we-die, yonke into evuthayo kanye nenqubo evuthayo yenqubo lapho kuvela khona iqembu elishisayo. Isisindo sokudutshulwa se-casting sichazwa yisifo sohlangothi, ubude nobubanzi be-plunger kanye nosayizi we-Sleeve / Chamber kanye ne-nowzle futhi badlala ingxenye ebhekwa ekwakhiweni okufayo. Lapho insimbi iye yaqina emgodini we-die (ithatha amasekhondi ambalwa) isigamu esisesigabeni somshini lapho kufakwa khona uhhafu wokufa okuvuthayo ukuze kuvulwe futhi kukhishwe ithuluzi. Ubuso obufayo bese bukhonjiswe ngohlelo lokufafaza, okufayo kuvalwa kanye nemijikelezo yenqubo futhi.
Ngenxa yalolu hlelo lwe- "luvaliwe" lwensimbi incibilikile / umjovo kanye nokunyakaza okuncane okwenziwe ngomshini okushisayo kweChamber Cast Canling kunganikeza umnotho ongcono wokukhiqiza. I-Zinc Metal Alloy isetshenziswa ngokuyinhloko ekucindezelweni kwegumbi elishisayo lokufa okunendawo enezinto eziphansi eziphansi ezinikezela ngezinzuzo eziphansi ze-Machines
Igama elibandayo liqhamuka kwinqubo yensimbi ebilisiwe ethululelwe emgqonyeni wamahlathi / umkhono odubula onamathiselwe ngesigamu esinqunyelwe isigamu sokufa ngemuva kwe-FITE TOLET TO TOLE TOLET. I-Molten Metal Holding / ancibilika imithwalo itholakala eduze njengoba kusebenza ngokuphela kokudutshulwa komshini wokudubula ukuze kukhishwe i-molate metal edingekayo emgodini ngamunye bese uthele insimbi ebilisiwe emgodini we-Sleeve / Shot Chamber. Ithiphu ye-plunger (okuyingxenye egqokekayo futhi eshintshashintshayo, inembe imishini efakwe kububanzi be-Shot Sleeve wangaphakathi ngokuthola imali evundile) exhunywe kwi-RAM yomshini idonsa insimbi encibilikisiwe egunjini lokudubula nangena emnyolweni obulawe. Umshini wokuphonsa ofa lapho ucelwa uzoqhuba isigaba sokuqala ukusunduza insimbi encibilikisiwe edlule umgodi othululayo esikhwameni. Ezinye izigaba ezengeziwe zenzeka ngaphansi kwezingcindezi ezandayo ze-hydraulic ezivela ku-RAM ukujova insimbi encibilikisiwe emgodini ofayo. Yonke inqubo ithatha imizuzwana, ingcindezi esheshayo neyaqinisa kanye nokwehla kwezinga lokushisa lensimbi kubangela insimbi ukuze iqiniswe emgodini ofayo. Isigamu esishukumisayo somshini wokujikijeleka kokufa siyavulwa (lapho ihafu oluhamba ngalo lwethuluzi lokufa lilungiselelwe) futhi likuphoqelele ukuqina okuqinile kobuso bethuluzi. Ukuphonsa kususwa, ubuso bokufa bukhonjiswe ngohlelo lokufafaza bese kuthi umjikelezo uyaphindwa.
Imishini ebandayo eChander ilungele ukulahlwa kwe-aluminium efa, izingxenye emshinini (umkhono we-shot, i-plunger tip) ingathathelwa indawo ngokuhamba kwesikhathi, imikhono ingaba yinsimbi yelashwa ukuze yandiswe ukuqina kwayo. I-Aluminium Alloy incibilike e-ceramic ehlakaniphile ngenxa ye-aluminium ephakeme ye-aluminium point ephezulu yokuncibilika kanye nesidingo sokunciphisa ubungozi bokuthola i-iron okuwubungozi ngaphakathi kwe-ferrous ama-rucibles. Ngoba i-aluminium iyinhlangano yensimbi ekhanyayo evikela ukuphonswa kwezinkohliso ezinkulu nezisindayo zokufa noma lapho kudingeka khona amandla nokukhanya okusondayo ekusakazelweni kwentela.
