Muchiito chese chekushandisa muchina wekugezesa otomatiki, mushandisi anosangana nedambudziko rakakura, iro "kupfuura-kupenya".Iyo nguva yekupenya yakarebesa uye kunaka kwepamusoro pemidziyo mold haina kunaka.Mumamiriro ezvinhu akajairika, "orange" ichaonekwa."Ganda", "gomba" uye mamwe mamiriro.Tevere, kambani yedu ichakuudza nzira yekugadzirisa dambudziko re "kupfuura-kukwenenzvera" kwe otomatiki polishing michina.

Kana iyo chigadzirwa workpiece ikaita "orenji peel", inonyanya kukonzerwa nekupisa kwakanyanya kweiyo mold surface layer kana yakawandisa carburization.Kana kugaya uye kuputira kudzvanywa kwakakura, nguva yekukuya uye yekupuruzira yakareba, izvo zvinokonzeresa kutaridzika kwemidziyo."Orange peel" mamiriro.Saka chii chinonzi "orange peel"?Kureva kuti, mupendero wepamusoro hauna kurongeka uye wakakasharara.Ndiro yesimbi yakaoma yakaoma inokwanisa kumira nekukuya nekuporiswa kudzvanywa kwakakura zvakati kuti, uye ndiro yakapfava isina simbi inogaya zvakanyanya kukuya nekupukuta.

Saka, sei kubvisa "orenji peel" yechigadzirwa workpiece?Isu tinofanirwa kutanga tabvisa iyo yakaremara pamusoro peturu, uye ipapo kukura kwezviyo kwakakora zvishoma pane nhamba yejecha yakashandiswa kare, uye kuderedza tembiricha yekudzima ne25 ℃, uye ipapo kushushikana kuri kuitwa.Chenesa, wozoshandisa mold ine nhamba yejecha yakatsetseka kukwenenzvera, wozopuruzira zvine simba rakareruka kusvika zvabuda zvinogutsa.

Izvo zvinonzi "pitting" ndiko kutaridzika kwemakomba-akaita semakomba ari pamusoro pechigadzirwa che workpiece mushure mekupenya.Izvi zvinonyanya kuitika nekuti mamwe asiri-metallic tsvina akasara achasanganiswa musimbi chigadzirwa workpieces, ayo anowanzo kuoma uye brittle oxides.Kana kukwenenzverwa kwekukwenenzverwa kwakanyanyisa kana kuti nguva yekupenya yakarebesa, tsvina iyi uye zvisaririra zvinoburitswa kubva pamusoro peplate resimbi isina tsvina, zvichigadzira dot-like micro-pits.Kunyanya kana kuchena kwesimbi yesimbi isina kukwana uye zvinyorwa zvezvakaoma zvakasara zvakasara zvakakwirira;nzvimbo yepamusoro yeplate yesimbi isina tsvina yakasvibiswa uye yakasvibiswa kana kuti ganda dema harina kucheneswa, "pitting corrosion" inowanzoitika.

Nzira yekubvisa sei "pitting" mamiriro?Iyo yepamusoro pechigadzirwa workpiece inokwenenzverwa zvakare.Hukuru hwezviyo hwejecha reforoma rinoshandiswa nhanho imwe yakakora kupfuura yaimboshandiswa kare, uye simba rekukwenenzvera rinofanira kuva diki.Mune ramangwana, shandisa matombo eoiri akapfava uye anopinza kune anotevera ekupukuta matanho, uye wozoita maitiro ekupukuta mushure mekuwana mhedzisiro inogutsa.Kana iyo otomatiki yekupuruzira muchina ichipuruzira, kana saizi yegrit isingasviki 1 mm, zvinodikanwa kudzivirira kushandiswa kwezvinyoro zvekupuruzira zvishandiso.Kusimba kwekukuya nekupukuta kunofanira kunge kuri kudiki sezvinobvira, uye nguva yacho inofanira kunge ipfupi sezvinobvira.
