Mazano ekushandisa core shooting machine
Muchina wekupfura wepakati chinhu chakakosha chemidziyo inoshandiswa muindasitiri yekugadzira yekugadzira jecha cores. Chiyero chayo chekushanda chinokanganisa zvakananga kunaka kwejecha cores, kubudirira kwekugadzira uye mutengo. Zvakafanana nematangi anoputika uye michina yekupfura, kuchengetedza ndiyo inonyanya kukosha, asi michina yekupfura yakakosha inoisa zvakanyanya kusimba pakutonga chaiko kwemaitiro paramita.
Aya anotevera matipi ekushandisa akazara emakina ekupfura (kunyanya anowanzo shandiswa kupisa musimboti bhokisi uye inotonhora yepakati bhokisi musimboti wekupfura michina) kubva pakugadzirira kusvika kugadzirisa.
Core musimboti: Kuchengetedzeka uye kugadzikana
Chengetedzo dzekuchengetedza: Masks egasi anofanirwa kupfekwa (kunyanya kana uchishandisa gasi reamine mumabhokisi anotonhora epakati), magirovhosi akakwira-anodzivirira kutonhora, magirazi ekudzivirira, uye shangu dzekuchengetedza. Magonhi ekuchengetedza uye midziyo yakavharika yemidziyo inofanirwa kunge iri mumamiriro akanaka uye inoshanda.
Kugadzikana kwemaitiro: Hunhu hwejecha cores hunoenderana zvakanyanya nekugadzikana maitiro paramita (sekumanikidza, nguva, tembiricha, nezvimwewo). Chero shanduko diki inogona kutungamira kune batch yezvakaremara zvigadzirwa.
Tsanangudzo Yakadzama yeCore Shooting Machine Usage Skills
I. Kugadzirira Usati Waita Homuweki
Iyo "Nhanhatu-Nzira yenhanho" yeCore Shooting muchina uye kuongorora mold:
Kuongorora kuchengetedza: Simbisa kuti gonhi rekuchengetedza, pneumatic / hydraulic locking mudziyo uye emergency stop bhatani riri kushanda nemazvo.
Mhepo uye kumanikidza: Tarisa kana kudzvanywa kwemhepo huru kwakadzikama (kazhinji 0.5-0.7MPa), dhonza mvura uye kusefa mhepo, uye tarisa kana zviito zveimwe solenoid vharafu necylinder zvinonzwa. Pressure ndiwo mweya wepakati.
Sandblasting system: Tarisa uone kana vharafu yejecha uye exhaust plug hazvina kuvharika uye kana mhete yekuvharisa yemusoro wejecha yakapfekwa. Bvisa jecha rasara kudzivirira kugadzikana.
Mold (core box): Uyu ndiwo musimboti. Bhokisi repakati rinofanira kunyatsocheneswa. Shandisa mhangura kana maturusi akakosha kubvisa chero yasara flash kana jecha raunga. Pfaya iyo mold release agent zvakaenzana (muzvishoma asi zvakaenzana; zvakawandisa zvinokonzeresa porosity defects).
Heating system (hot core box) : Tarisa uone kana tembiricha yekudziya ndiro yakaenzana uye yakagadzikana, inosvika pakukosha kwakaiswa (kazhinji 180-280 degree). Eresa chaiyo yepakati bhokisi tembiricha pane akawanda mapoinzi ne thermometer.
Jecha rekushandisa system: Ita shuwa kuti mune jecha rakakwana rakakwana muhopper yejecha, uye jecha reshiyo yejecha (resin, kurapa mumiriri, nezvimwewo) yemusanganiswa wejecha yakagadzikana uye yakarurama.
Kusimbiswa kweiyo core shooting process parameters
Zvinoenderana nechimiro, saizi uye kuomarara kwejecha core, isa kana simbisa anotevera epakati paramita:
Jecha kupfura kudzvinyirirwa uye nguva: Kusakwana kudzvanywa kana kupfupika kwenguva kuchaita kuti jecha repakati rirege "kupfurwa zvakasimba" uye risununguke. Kuwedzeredza kudzvanywa kana kureba kwenguva kunogona kutungamira kune "kupfuura", zvichiita kuti mucous membrane kana jecha repakati riite brittle.
Kurapa nguva (yehot core boxes)/kuvhuvhuta nguva (yechando core boxes) : Kana nguva yacho isina kukwana, kusimba kwejecha core hakuzokwani. Kana nguva yacho yakarebesa, inoderedza kushanda zvakanaka uye inogona kutungamira mukupisa kana jecha repakati kuita brittle.
Core ejection uye musimboti kubviswa: Gadzirisa sitiroko uye nekumhanya kweiyo core ejection tsvimbo kuti ive nechokwadi ejection yakatsetseka pasina kupaza iyo jecha musimboti.
Ii. Kushanda panguva yepakati yekupfura muchina wekushanda
Maitiro ekushanda akaenzana
Kuvhara Mold: Mushure mekuona kuti bhokisi repakati rakachena zvachose, tanga nzira yekuvhara mold uye simbisa kuti yakakiyiwa panzvimbo.
Sandblasting: Dzvanya bhatani rejecha uye nyatso tarisisa ruzha rwejecha. Ruzha rwakajairika rwejecha kupfura ipfupi asi ine simba "sizzle". Ruzha rusinganzwisisike runogona kuratidza kuvharika, ukuwo ruzha rusinganzwisisike runogona kuratidza kubuda kwemhepo.
Kurapa / Kuvhuvhuta: Mirira nguva yakatarwa. Usafanovhura musuwo panguva ino.
Mold kuvhurika uye core kutora: Vhura gonhi rekuchengetedza uye tarisa kana jecha repakati rakasundirwa kunze nekubatwa zvakanaka. Izvo zvinorambidzwa zvachose kutora musimboti wakananga kubva mukuumbwa neruoko kudzivirira scalding (hot core box) kana kukuvadza mold. Shandisa pneumatic clamping maturusi kana mapallets.
Chekutanga chinyorwa chekuongorora uye maitiro ekutarisa
Chekutanga chinhu chekuongorora: Mushure mekugadzirwa kwekutanga jecha musimboti, muchina unofanirwa kuvharwa kuti uongororwe zvizere.
Chitarisiko: Ingave yakasimba, isina makona, kusununguka kana kutsemuka.
Zviyero: Tarisa zviyero zvakakosha nemidziyo yekuyeresa kana mapallets.
Kusimba: Shandisa jecha core yekuyedza muchina kana kuti utyore zvine mwero neruoko pane-zvisiri zvakakosha.
Kuongorora kwemaitiro: Dzokorora kuongorora panguva nenguva (senge makumi matatu kusvika makumi mashanu zvinhu). Tarisa shanduko yehuremu hwejecha core (iyo inogona kuratidza zvisina kunanga kuzara kwejecha rakapfurwa).
Maitiro ekugadzirisa zvakanaka
Kugadzirisa dambudziko rejecha rejecha risina kukwana: Chekutanga, wedzera jecha jecha pressure, wobva wawedzera jecha jecha nguva. Tarisa kana iyo exhaust plug yakavharwa.
Kugadzirisa dambudziko rekunamira kwe mold: Tarisa uone kana iyo yekuburitsa yekupfapfaidza inobudirira, dzikisa tembiricha ye mold (yemabhokisi anopisa epakati), kana kuderedza huwandu hweanorapa anoshandiswa (yeanotonhora epakati mabhokisi). Tarisa kupedzwa kwepamusoro kwe mold.
Kugadzirisa dambudziko resacha core brittleness: Inogona kunge yakakonzerwa ne-kupora zvakanyanya (nguva yakarebesa kana tembiricha yakanyanya) kana kusakwana kuwedzera resin.
Sandblasting matekiniki ejecha akaomesesa cores: Kune jecha cores ane akadzika maburi uye matete madziro, zvingave zvakafanira kugadzirisa nzvimbo yejecha bhomba kana kutora akakosha maitiro senge stepwise sandblasting / vacuuming.
Iii. Kugadziriswa kweiyo core Shooting Machine mushure meKushanda
Zuva nezuva/Shift kupera basa:
Kunyatsochenesa jecha: Mushure mekudzima magetsi nemhepo, chenesa jecha rese rasara muhumburumbira hwekupfura nejecha, pakushanda uye mold.
Kugadzirisa Mold: Chenesa bhokisi repakati, pfapfaidza zvishoma zvekudzivirira mold kuburitsa agent, wobva wavhara mold uye uichengete kudzivirira ngura kana deformation.
Exhaust sefa: Inobvisa hunyoro nemafuta mavara kubva kumhepo yedunhu system.
Nguva dzose kuchengetedza
Gara uchiongorora uye kutsiva nhengo dzisina njodzi sevharuvhu yekupfura jecha, mhete yekuisa chisimbiso uye solenoid vharafu.
Chenesa kana kutsiva exhaust plug sefa skrini.
Zora njanji dzegwara uye mapini ekutungamira.
Unyanzvi hwepamusoro uye mazano
Preheating of the mold: Isati yagadzirwa, mold inofanira kunge yakanyatsopisa kusvika kune yakagadzikana yekushanda tembiricha; kana zvisina kudaro, mashoma ekutanga ejecha cores ese achange ari epasi zvigadzirwa.
Kutarisira zvinhu zvejecha: Tembiricha uye hunyoro hwejecha rakasvibira zvine chekuita nemaitiro. Inokurudzirwa kudzora tembiricha yejecha mbishi pa25-35 dhigirii uye mwando uri pasi pe0.3%. Shandisa jecha tembiricha regulator.
Kurekodha uye optimization
Kushandirapamwe: Iyo yakakosha yekupfura muchina anoshanda inofanirwa kuchengetedza kutaurirana kwepedyo nemusanganiswa wejecha, vashandi vekugadzirisa mold, uye kunyungudutsa nekudira vashandi. Nyaya dzehutano dzinoda kuongororwa zvine hungwaru.
Pfupiso: Kushandiswa kwemichina yekupfura yepakati inyanzvi yetekinoroji maitiro. Iyo yakakosha inogona kupfupikiswa se "zvinomwe zvikamu zvekugadzirira, zvikamu zviviri kushanda, uye chikamu chimwe chekugadzirisa". Anoshanda akatanhamara haangori mudziyo wekushandisa asiwo yekutarisa uye adjutor yemaitiro paramita. Ivo vanofanirwa kuve nehunyanzvi hwekutarisa (kutarisa jecha cores uye kuteerera kune ruzha) uye kwakaomarara kugona kuongorora. Kunyatsotevedzera maitirwo ekushanda uye kuramba uchiunganidza ruzivo ndidzo chete nzira dzekuti tive nechokwadi chekugadzirwa kwemhando yepamusoro-.
