Ukuhlelwa komatshini wokubumba kunye nokuqaliswa komsebenzi

Ukuhlelwa komatshini wokubumba kunye nokuqaliswa komsebenzi
Umatshini wokubumba sisixhobo esingundoqo esisetyenziselwa imveliso yokuphosa ukuvelisa iimbumba zesanti (i-molds). Umsebenzi wayo ongundoqo kukuguqula isanti ebumbayo ekhululekileyo ibe sisingundo sesanti esinamandla athile kunye nokuchaneka kokugalela isinyithi esinyibilikisiweyo. Oku kulandelayo luhlelo kunye nokuqaliswa komsebenzi womatshini wokubumba.
1. Ihlelwa ngendlela yokubumba (umgaqo wocinezelo)
Le yeyona ndlela ingundoqo yokuhlela, ebonisa inkqubo yophuhliso kunye nenqanaba lobuchwepheshe.
1. Umatshini wokubumba wokungcangcazela
Umgaqo: Ukusebenzisa umoya oxinzelelweyo ukwenza i-worktable (okanye ibhokisi yesanti) kunye nesanti yokubumba iphakame ngokukhawuleza ize ivele ngokukhawuleza, ivelise ukungcangcazela komothuko, okubangela ukuba isanti ebumbayo ihlanganiswe ngenxa yamandla angenayo.
Iimpawu: Izixhobo ezilula, ixabiso eliphantsi. Nangona kunjalo, inengxolo ephezulu, ukusetyenziswa kwamandla aphezulu, ukubumbana okungalinganiyo (ukukhululeka okuphezulu kunye nokuqina okuphantsi), imveliso ephantsi, kunye neemfuno eziphezulu zesiseko. Ngokusisiseko iye yapheliswa okanye isetyenziswa kuphela ngezihlandlo ezikhethekileyo ezifana nolondolozo.
2. Umatshini wokubumba impembelelo
UmGaqo: Okokuqala, iyangcangcazela ukwenza isanti yokubumba esezantsi ihlangane, kwaye emva koko isebenzisa isilinda esicinezelayo (okanye isilinda sobuchwephesha behydraulic) ukongeza ukucinezelwa komphezulu wokungunda kwesanti ukuphucula ukufana ngokubanzi.
Iimpawu: Ingcono kunongcangcazelo olulula, kwaye yayikade sesona sixhobo siphambili kwiifektri zokusabisa ezincinci naphakathi{0}eziphakathi. Nangona kunjalo, isenayo ingxolo kunye neengxaki zokusebenza kakuhle, kunye nokuqina komphezulu kunye nokuthe tye kwecavity yi-avareji.
3. Ukubumba umatshini wokubumba
UmGaqo: Ukusebenzisa ngokulula uxinzelelo lomoya okanye uxinzelelo loxinzelelo lwehydraulic-intloko ecofayo eqhutywayo (intloko ecofayo ecaba, ukwenza intloko ecofayo, okanye kaninzi{1}}ucofa intloko yoqhagamshelwano) ukudibanisa ngokwestatiki isanti ebumbayo ukusuka phezulu okanye ngaphantsi kwebhokisi yesanti. Uphawu:
Ukudibanisa okulula: Isakhiwo esilula, ingxolo ephantsi, kodwa ukudibanisa kuncipha kakhulu kwicala lokuphakama (qina phezulu kwaye ukhulule ezantsi).
I-Multi- yokudibana koqhagamshelwano: Isilinda esincinci se-hydraulic sentloko nganye siyakwazi ukuziqhelanisa nokwahluka kobude bomngundo, kwenze ukuxinana kufane ngakumbi kwaye kukulungele ukubumba okunzima.
Uxinzelelo oluphezulu{{0}loxinzelelo oluphezulu: Ukusebenzisa uxinzelelo oluphezulu oluthile (ngokuqhelekileyo> 0.7 MPa), ukuqina okuphezulu kunye nokuchaneka okuphezulu kokubumba kwesanti kunokufumaneka.
4. Umatshini wokubumba oxinzelelekileyo
Umgaqo: Ukusebenzisa umoya ocinezelweyo ukudubula ngoko nangoko isanti ebumbayo ngesantya esiphezulu kwibhokisi yesanti (ukuzalisa isanti), kulandele{0}}ukuxinezeleka koxinzelelo oluphezulu. Le ngoku yeyona nto iphambili kwaye isebenzayo itekhnoloji yokubumba.
Iimpawu: Ukuzaliswa kwesanti ngokukhawuleza kunye nokufana okufanayo, umphumo omuhle wokudibanisa, ukuchaneka kwesikhunta esiphezulu sesanti, kunye nokuzenzekelayo okulula. Ingohlulwa ibe yibhokisi -inyuswe ucinezelo kunye no{2}}ibhokisi{3}}inyuswe uxinzelelo.
Umngundo wokwahlula ngokuthe nkqo ngaphandle komatshini wokubumba woxinzelelo lwebhokisi (ofana nomgca we-DISA): Ukubumba, ukubopha okungundoqo, ukugalela, kunye nokupholisa zonke ziqhutyelwa kumgca wemveliso othe nkqo, onemveliso ephezulu kakhulu, elungele ukulahlwa kwenqanaba elikhulu, eliphakathi{1}}elifana ne-brake discs, imizimba ye-clamp, njl.
Umatshini wokubumba wokubumba owahlukanisiweyo othe tyaba: Ingohlulwa ibe ngundoqo-umatshini wokubumba wokukhulula kunye nebhokisi{1}}umatshini wokubumba oxhonyiweyo (ohlala usenza umgca wokubumba ozenzekelayo).

Umgaqo: Okokuqala, vuthela umoya oxinzelelweyo kwibhokisi yesanti ukuze uqale ukunyibilikisa isanti ebumbayo kwaye ugcwalise onke amalungu ebhokisi yesanti (phambi-ukucutheka), emva koko wenze uqhagamshelo oluninzi ngoxinzelelo oluphezulu oluthile. Uphawu:
Ukubumbana komngundo wesanti kuphezulu kakhulu kwaye kufana ngokugqithisileyo, kunye nobunzima obungaphezulu kwama-90.
Ukuchaneka kwe-demolding kuphezulu, kwaye imilinganiselo yokuphosa ichanekile, kunye nomphezulu ogudileyo.
Ulwakhiwo lwezixhobo lunzima kwaye utyalo-mali lukhulu. Lolona khetho lukhethwayo lokuvelisa{1}}umgangatho ophezulu kunye nokubunjwa okuntsokothileyo (okufana neebhloko zenjini kunye namaqweqwe eemoto).
6. Umatshini wokuBumba iMpembelelo
Umgaqo: Ukusebenzisa isantya somxhuzulane (okufana nokuwa ngokukhawuleza kunye neempembelelo emva kwevacuum ebambe ibhokisi yentlabathi) okanye amaza othusayo aveliswa kugqabhuko-dubulo lwerhasi, isanti ifumana amandla ekinetic ngexesha elifutshane kakhulu kwaye ixinene.
Iimpawu: Isantya sokudibanisa ngokukhawuleza, ukufana kakuhle kwesikhunta sesanti, ingxolo ephantsi kunohlobo lwe-vibration compaction. Nangona kunjalo, iimfuno zokugcina izixhobo ziphezulu.
7. Cinezela uMshini wokuBumba (usetyenziswa ikakhulu ukwenza iintsimbi zesanti)
Umgaqo: Isanti engundoqo itofwa kwibhokisi yentsimbi efudunyeziweyo, kwaye umbindi wesanti wenziwe bubushushu{0}ukuqina kwesanti yentlaka ye-thermosetting. Ngokuqhelekileyo ibhekisa kumatshini wokutofa (ibhokisi engundoqo eshushu, ibhokisi engundoqo ebandayo).
Iimpawu: Isetyenziselwa ukuvelisa-ukuchaneka okuphezulu kunye{1}}nokuqina okuphezulu kweecores zesanti.
II. Ukuhlelwa ngokweSand Mold State
Nge-ibhokisi yoMshini wokuBumba: Usebenzisa ukubumba kwesanti esisigxina ukubumba, kwaye emva kokubumba, ukubumba kwesanti kunye nebhokisi yesanti kuyathuthwa kwaye kugalelwe. Inobubhetyebhetye obuhle kwaye ifanele ubukhulu kunye nobukhulu obuphakathi{2}}ukubunjwa kunye nemigca yokubumba.
Ngaphandle - kwebhokisi Umatshini wokuBumba: Ngexesha lokubumba, isakhelo setemplate sisetyenzisiwe, kwaye emva kokuba isikhunta sesanti senziwe, senza "ibhloko yesanti" eqinileyo ngokwayo, kwaye akukho mfuneko yebhokisi yesanti yokubumba. Igcina iindleko kunye nolawulo lweebhokisi zesanti kwaye zinemveliso ephezulu. Ummeli ngumatshini wokubumba ucinezela othe nkqo.
De-ibhokisi Umatshini wokuBumba: Ngexesha lokubumba, i-mold yesanti ekhutshwayo (i-sleeve mold) iyasetyenziswa. Emva kokubunjwa, ukungunda kwesanti kuyasuswa, kwaye ukubumba kwesanti kukwimeko ebambene ngokufana nangaphandle kwe-bhokisi. Yindlela eqhelekileyo yokuveliswa kwebhetshi yee-castings ezincinci.
III. Ukuhlelwa ngokoMkhombandlela woMphezulu woKwahlula
Umatshini wokubumba othe tyaba wokuqhekeka: Umphezulu wokuqhekeka ukwicala elithe tye, elihambelana nomkhwa wokubumba wendabuko. Kukulungele ukufaka ingundoqo, kwaye inoluhlu olubanzi lwesicelo.
Umatshini wokuBumba oQoqoqqqqqqqqqqqqqqqqzazazamla nkqo: Umphezulu wokwahlula ukwicala elithe nkqo. Ummeli oqhelekileyo lukwahlula ngokuthe nkqo ngaphandle{1}}kwebhokisi umatshini wokubumba. Inokusetyenziswa kwendawo ephezulu kwaye izenzekela ngokupheleleyo kunye nemveliso eqhubekayo.
IV. Intshayelelo yeMisebenzi enguNdoqo
Ukuzalisa isanti: Gcwalisa ibhokisi yesanti okanye isakhelo setemplate ngobungakanani besanti ngokukhawuleza nangokulinganayo.
Ukudibanisa: Ukwandisa ubuninzi besanti ngeendlela ezibonakalayo (ukungcangcazela, ukucinezela, ukuhamba komoya, impembelelo, njl.
I-Demolding: Emva kokuba i-sand mold idibene, ngokuchanekileyo kwaye ihlulwe ngokufanelekileyo imodeli (isikhunta) kwi-mold yesanti ukwenza i-cavity. Eli linyathelo eliphambili lokuqinisekisa ukuchaneka komgangatho wokusaswa.
Imisebenzi eNcedisayo (kumatshini wokubumba ozenzekelayo):
Ukuthuthwa kokungunda kwesanti kunye nokubeka indawo.
Template replacement (kwimveliso ezininzi-ezihlukeneyo).
Ukufaka ii-cores, ukuvala ukubumba. Ukukhutshwa kwesanti ngundo kunye nokuhambisa.
