Gupfa
Gupfa gupfa ni uburyo bwo gukora bukoreshwa mu gukora ibyuma bifite uburinganire buringaniye kandi burangije.Harimo guhatira icyuma gishongeshejwe mukibumbano cyumuvuduko mwinshi.Umuyoboro wububiko urema ibyuma bibiri bikomye bipfa gukorerwa muburyo bwifuzwa.
Inzira itangirana no gushonga ibyuma, mubisanzwe aluminium, zinc, cyangwa magnesium, mu itanura.Icyuma gishongeshejwe noneho gishyirwa mubibumbano kumuvuduko mwinshi ukoresheje imashini ya hydraulic.Icyuma kirakomera vuba imbere mububiko, kandi ibice bibiri byububiko byafunguwe kugirango birekure igice cyarangiye.
Die casting ikoreshwa cyane mugukora ibice bifite imiterere igoye nurukuta ruto, nka moteri ya moteri, amazu yohereza, hamwe nibice bitandukanye byimodoka nindege.Inzira irazwi cyane no gukora ibicuruzwa byabaguzi, nkibikinisho, ibikoresho byo mu gikoni, na elegitoroniki.
Umuvuduko wo Gupfa
Gupfa gupfa ni inzira yihariye yateye imbere cyane cyane mu kinyejana cya 20.Inzira y'ibanze igizwe na: icyuma gishongeshejwe gisukwa / kigaterwa mu cyuma kandi binyuze mu muvuduko mwinshi, umuvuduko uhoraho kandi ukaza umurego (mu gitutu cyo gupfa) no gukonjesha icyuma gishongeshejwe birakomera kugira ngo bikore neza.Mubisanzwe, inzira ubwayo ifata amasegonda make kandi nuburyo bwihuse bwo gukora ibicuruzwa biva mubikoresho fatizo.Gupfa gupfa bikwiranye nibikoresho nka amabati, isasu, zinc, aluminium, magnesium kugeza kumuringa wumuringa ndetse nibyuma byuma nkibyuma bitagira umwanda.Amavuta nyamukuru akoreshwa uyumunsi mugupfa gupfa ni aluminium, zinc na magnesium.Kuva imashini zipfa kwambere zerekanaga ibikoresho bipfa kwerekera muburyo bugororotse kugeza kurwego rusanzwe rwerekezo rwa horizontal nicyerekezo, imirongo ine ihuza umurongo hamwe na mudasobwa igenzurwa byuzuye inzira igenda itera imbere mumyaka yose.
Inganda zimaze gukura zikora imashini ikora ku isi yose, ikora ibice bya porogaramu zitandukanye, ibyinshi muri byo bizagerwaho bivuye ku bo ubwabo kuko ibicuruzwa bikoreshwa mu rupfu biratandukanye.
Inyungu zumuvuduko upfa guta
Zimwe mu nyungu z'umuvuduko ukabije upfa guta:
• Inzira ikwiranye numusaruro mwinshi.
• Kora ibintu byoroshye cyane ugereranije nibindi bikoresho byo gukora ibyuma (urugero: gutunganya).
• Ibikoresho byimbaraga nyinshi byakozwe muburyo bwo gukina (ukurikije igishushanyo mbonera).
• Gusubiramo ibipimo.
• Urukuta ruto rushoboka (urugero: 1-2.5mm).
• Kwihanganira umurongo mwiza (urugero: 2mm / m).
• Kurangiza neza neza (urugero 0.5-3 µm).
Inzira yumuvuduko wicyumba gishyushye bipfa gushiramo birimo gushonga ibyuma byinjira mumatanura aherereye hafi / ntaho bihuriye nigice cya kabiri cyagenwe cyimashini zipfa no gutera ibyuma byashongeshejwe binyuze mumashanyarazi yarengewe na gooseneck na nozzle no kwinjira igikoresho cyo gupfa.Gooseneck na nozzle bisaba gushyushya kugirango birinde gukonjesha ibyuma mbere yuko bigera mu cyuho cyo gupfa, ibintu byose bishyushya hamwe nicyuma gishongeshejwe muriki gikorwa niho hava icyumba gishyushye.Uburemere bwo kurasa buterwa na stroke, uburebure na diameter ya plunger kimwe nubunini bwikiganza / icyumba na nozzle nayo igira uruhare rugomba kwitabwaho mugupfa.Iyo icyuma kimaze gukomera mu cyuho cyo gupfa (bifata amasegonda make gusa) igice cyimuka cyimashini ya mashini yimuka igice cyurupfu cyagenwe kugirango ifungurwe kandi casting isohoka mumaso yapfuye ikurwa mubikoresho.Amaso apfa noneho asizwe amavuta akoresheje sisitemu yo gutera, ipfa rifunga kandi inzira irongera.
Kubera ubu buryo "bufunze" ibyuma bishonga / inshinge hamwe na mashini ntoya yimashini ishyushye urugereko rushobora gutanga ubukungu bwiza kubyara umusaruro.Icyuma cya Zinc gikoreshwa cyane cyane mubushyuhe bwicyumba gishyushye bipfa guterwa bifite aho bishonga cyane bitanga izindi nyungu zo kwambara gake kumashini (inkono, gooseneck, amaboko, plunger, nozzle) ndetse no kwambara gake kubikoresho bipfa (ibikoresho birebire cyane ubuzima ugereranije na aluminium apfa ibikoresho byo gutara - bitewe no kwemerwa neza).
Izina imbeho ikonje ituruka mugikorwa cyicyuma gishongeshejwe gisukwa mucyumba gikonje / urushyi rwamasasu rufatanyirijwe mu gice cyagenwe gipfa gupfa inyuma yicyuma cyagenwe cyagenwe.Icyuma gishongeshejwe gifata / gushonga mu itanura mubisanzwe giherereye hafi nkuko bifatika kugeza kurasa kumashini yimashini ipfa kugirango umukoresha wintoki cyangwa icyuma gisuka mu buryo bwikora gishobora gukuramo icyuma gishongeshejwe gisabwa kuri buri kirasa / cycle hamwe nigitereko hanyuma ugasukaho icyuma gishongeshejwe mu mwobo usuka mu cyumba cy'intoki.Isonga ya plunger (nigice gishobora kwambarwa kandi gisimburwa, gikozwe neza kuri diametre yimbere yimbere hamwe namafaranga yo kwagura amashyuza) ihujwe nintama yimashini isunika icyuma gishongeshejwe mucyumba cyo kurasa no mu cyuho cyo gupfa.Imashini yo gupfa iyo isabwe izakora icyiciro cya mbere cyo gusunika icyuma gishongeshejwe hejuru yumwobo usuka mu ntoki.Iyindi ntambwe ibaho bitewe n’umuvuduko mwinshi wa hydraulic uva muri ya mpfizi y'intama kugirango utere icyuma gishongeshejwe mu cyuho.Inzira yose ifata amasegonda, umuvuduko wihuse kandi wiyongera kimwe no kugabanuka kwubushyuhe bwicyuma bituma icyuma gikomera mumyanya ipfa.Igice cyimuka cya platine yimashini yipfuye irakingura (muricyo gice cyimuka cyigikoresho cyo gupfa gishyizwe kuri) kandi ikanasohora imyanda ikomeye mumaso yipfuye.Gukina gukurwaho, isura yipfuye isizwe hamwe na spray hanyuma uruziga rusubirwamo.
Imashini ya chambre ikonje ikwiranye no guta aluminiyumu, ibice kuri mashini (kurasa kurasa, plunger tip) birashobora gusimburwa mugihe, amaboko ashobora kuvurwa ibyuma kugirango yongere igihe kirekire.Aluminiyumu ya aluminiyumu yashongeshejwe muri ceramic ikomeye cyane bitewe na aluminium ugereranije no gushonga cyane kandi bikenewe kugabanya ibyago byo gutwara ibyuma bikaba ari ibyago biri mumababi ya ferrous.Kuberako aluminiyumu ari icyuma cyoroheje gisa nicyuma gitanga ibinini binini kandi biremereye bipfa cyangwa aho bisabwa kongera imbaraga numucyo mubipfa bipfa.
