cryogenic defiashing tekinoroji yakatanga Kugadzirwa muma1950s.Mukugadzirisa kwekugadzira michina ye cryogenic defiashing, yakapfuura nenguva nhatu dzakakosha.Tevera mune ino chinyorwa kuti uwane kunzwisisa kwese.
(1) Chekutanga cryogenic deflashing muchina
Iyo dhiramu yakaomeswa inoshandiswa semudziyo wekushanda wechando, uye chando chakaoma chinotanga kusarudzwa sefiriji.Zvikamu zvinogadziriswa zvinotakurwa mudhiramu, zvichida pamwe nekuwedzera kweimwe inopikisana inoshanda midhiya.Tembiricha iri mukati medhiramu inodzorwa kuti isvike kune iyo mipendero ine brittle nepo chigadzirwa pachacho chinoramba chisina kukanganiswa.Kuti uwane chinangwa ichi, ukobvu hwemapendero hunofanira kunge huri ≤0.15mm.Iyo ngoma ndiyo chikamu chikuru chemidziyo uye ine octagonal muchimiro.Chinokosha ndechekudzora nzvimbo yekubata kweiyo ejected media, zvichibvumira kuti kutenderera kutenderera kuitike kakawanda.
Iyo ngoma inotenderera inopesana newachi kuti idonhe, uye mushure menguva yakati rebei, mipendero inova brittle uye dhizaini inopedzwa.Chikanganiso chechizvarwa chekutanga chakaomeswa edging haina kukwana edging, kunyanya masara maflash edge pamagumo emutsara wekuparadzanisa.Izvi zvinokonzerwa nekusakwana kwekugadzira mold kana kunyanyisa kukora kwerubha layer pamutsara wekuparadzanisa (kupfuura 0.2mm).
(2) Yechipiri cryogenic deflashing muchina
Yechipiri cryogenic deflashing muchina yakaita kuvandudzwa katatu zvichienderana nechizvarwa chekutanga.Kutanga, firiji inoshandurwa kuita nitrogen yemvura.Dry ice, ine sublimation point ye -78.5 ° C, haikodzeri mamwe e-low-temperature brittle rubbers, akadai sesilicone rubber.Liquid nitrogen, ine kuvira kwe -195.8 ° C, inokodzera marudzi ese erubha.Chechipiri, kunatsiridzwa kwakaitwa mugaba rinobata mativi anofanira kuchekwa.Inoshandurwa kubva padhiramu rinotenderera kuenda kubhandi rekutakura rakaita sedhiri semutakuri.Izvi zvinobvumira kuti zvikamu zvidonhe mumugero, zvichideredza zvakanyanya kuitika kwemavara akafa.Izvi hazvingonatsiridza kushanda zvakanaka chete asiwo zvinowedzera kurongeka kweedging.Chechitatu, pachinzvimbo chekuvimba chete nekudhumhana pakati pezvikamu kuti ubvise mitsetse yemwenje, midhiya inoputika yakatsetseka inounzwa.Simbi kana yakaoma epurasitiki pellets ane particle size ye 0.5 ~ 2mm inopfurwa pamusoro pezvikamu pamutsara wekumhanya we2555m / s, zvichigadzira simba rakakosha.Kuvandudza uku kunopfupisa zvakanyanya nguva yekutenderera.
(3) Yechitatu cryogenic deflashing muchina
Yechitatu cryogenic deflashing muchina kuvandudzwa kunoenderana nechizvarwa chechipiri.Chigaba chezvikamu zvichachekwa chinoshandurwa kuita bhasikiti rezvikamu rine madziro ane maburi.Aya maburi anovhara madziro ebhasiki ane dhayamita inosvika 5mm (yakakura kupfuura dhayamita yepurojekiti) kubvumira mapurojekiti kuti apfuure nemumakomba zvakanaka uye achidzokera kumusoro kwemidziyo kuti ishandiswezve.Izvi hazvingokwidzi simba rinoshanda remudziyo asiwo zvinoderedza huwandu hwekuchengetera kweiyo impact media (projectiles) .The partics basket is not vertically positioning in the trimming machine, asi ine kumwe kurerekera (40°~60°).Iyi kona yekurerekera inokonzeresa kuti dengu ritenderere zvine simba panguva yekugadzira nekuda kwekubatanidzwa kwemasimba maviri: imwe isimba rekutenderera rinopihwa nebhasiketi pacharo richidonha, uye imwe isimba repakati rinogadzirwa neiyo projectile impact.Kana mauto maviri aya abatanidzwa, kufamba kwe360 ° omnidirectional kunoitika, zvichibvumira zvikamu kuti zvibvise mapeji emwenje zvakafanana uye zvizere mumativi ese.
