1, Iyo pre-deformation dhizaini ndiyo kiyi

Nezve auto mhepo & mvura tangi chigadzirwa chepurasitiki mold, iyo yemhando yekudzora dhizaini nekugadzira yakanyanya kuoma kupfuura yakajairika mhando, sezvo iyi mhando zvikamu zvaiwanzo kuumbwa nechinhu PA6 (PA66) + GF (30-35%) musanganiswa, uye izvi mhando yezvinhu zviri nyore kuwana deformation panguva yekuumba maitiro, uye inoenderana chigadzirwa saizi zviri nyore kuve kunze kwekushivirira. Naizvozvo, kujairana neiyo deformation yenguva dzose, zvino kuita iyo pre-deformation dhizaini yakavakirwa pane ruzivo uye CAE ongororo inokonzeresa mukutanga dhizaini yave kiyi yekubudirira kwekugadzira mold.

Chikwata cheEnuo mold chine makore anopfuura gumi 'ruzivo rwekugadzira pre-deformation mold, uye vakashandira Valeo, Mahle-behr, Delphi nevamwe vane mukurumbira pasi rose zvikamu zvemotokari vatengi. Pano tinosuma muchidimbu ruzivo rwedu pa auto air & water tank mold kugadzira. Chokwadi, makambani akasiyana ane maitiro akasiyana, kana muverengi anodiwa aine maonero akasiyana, gamuchirawo noushamwari kuti utaure nesu.

2, Kuongorora zvikamu zvekudhirowa, kujekesa nzvimbo dzakakosha dzechigadzirwa uye saizi

Kuti unzwisise nzvimbo dzakakosha dzechigadzirwa uye hukuru hunoenderana nehukuru hunogara iri nhanho yekutanga kana zvigadzirwa zvevatengi zvakadhirowa zvasvika, wobva watarisa zvakanyanya kukosha ikoko, senge chigadzirwa "End surface" ("End surface" yaidiwa zvakanyanya kutwasanuka, flatness. uye gadzira saizi yekushivirira, uye zvimwe zvikamu zvechikamu chechigadzirwa zvichatevera kushanduka kwavo),"Tube orifice" nzvimbo (yero ye "tube orifice" yakakoshawo, kazhinji kumira, cylindrical uye dimensional kushivirira kunodiwa) uye chigadzirwa " Boss” uye “U-shape” mbabvu nezvimwewo, zvinoratidzwa pazasi:

Nezve mold nyowani, ita pre-deformation pachigadzirwa (uchiita "material compensation" kune yakapesana yekufungidzirwa deformation pachine nguva maererano neruzivo uye CAE ongororo, kurudzira kuti vagadzirise mushure meiyo deformation yaitwa). Mushure meyedzo yekuumbwa, kuita zvimwe zvidiki shanduko zvichibva pane chaiyo deformation yekuumbwa kwechigadzirwa, kugadzirisa epurasitiki geometry, chimiro uye chinzvimbo uye zvichingodaro.

3, Kudhirowa zvigadzirwa.

Kufambisa ramangwana mold optimization, kudhirowa nyowani 3D chigadzirwa data tega zvinoenderana nechigadzirwa chemutengi inodiwa (yakakosha ma paramita anofanirwa kuchengetwa). Kuona iyo zvigadzirwa deformation kukosha, yakasanganiswa ne mold flow analysis uye ruzivo rwekugadzirisa chigadzirwa data, pazasi unogona kuona ane ruzivo deformation maitiro:

Pano, mamwe matipi anofara kugovaniswa panguva yekudhirowa patsva, senge: gara uchitanga kudhirowa "Base end surface" nzvimbo, zvinoenderana neiyo deformation kukosha kudhirowa kutwasuka, flatness curve pamucheto wechigadzirwa, tarisa kune iwo macurves. ku "Tambanudza"(UG command) kutwasanuka pamusoro. Nzvimbo dzakadzikama dzinoitwa ne "Border" (UG command). Iyi nhanho yakakosha, kufambisa shanduko yenguva yemberi, dhiza curve kutanga, usa "tambanudza" (UG command) pamusoro zvakananga, wozoshandisa deformation yepasi yekutwasuka tora chimiro chechigadzirwa ne "Offset" (UG command). Kuti udzivise kushandura yakawandisa mold zvikamu panguva inotevera mold optimization, kuita epurasitiki zvinhu kucheka pachigadzirwa "Base end surface" nzvimbo, wozozvidzoreredza muT1-T3 shanduko zvichibva pane chaiyo chigadzirwa deformation (pamwe nepurasitiki).

Mazano paybe anobatsira:

1. Usateedzera zvigadzirwa zvemutengi kumusoro sezvinobvira, edza kuzvidhirowa wega. Saka kuti, kune inotevera mold shanduko iri nyore kuchinjwa, kusanganisira kukora kwemadziro. kana maumbirwo ari kopi kubva kune chigadzirwa chevatengi saka mushure mekushandurwa kwakawanda, 3D data inowana kukanganisa.
2. Mukuita kwekudhirowa, zvakanyanya sezvinobvira kutarisa mutengi 2/3D chigadzirwa data kudzivirira ivo vakasiyana.

4, Iyo inogoneka deformation maitiro nezve chigadzirwa chakakosha chikamu

1, The deformation yechigadzirwa "Base end surface"

Nepazvinobvira kuita kudzikisa chiito pane epurasitiki zvinhu pakutanga, zvinogona kudzivirira kudzoreredza zvikamu zve mold sezvinobvira. Mutsara mutsvuku pazasi unoratidza chigadzirwa chinofungidzirwa deformation maitiro. ndapota cherechedza mbabvu dze "Boss" kana "U-shaped" kana zvinhu zvine hukama zvinofanirwa kufambiswa ne "Base end surface" pamwe chete (Zvimwe zvezvinhu zviri pasi peshefu zvinodzika pasi 0.5mm, ipapo "Boss" anodzikawo pasi 0.5 ), wozodhirowa vamwe. Zvinokurudzirwa kushandisa "pamusoro" (UG command) kuvadhirowa.

2, Iyo chigadzirwa deformation ye "Tube orifice"

Iyo "R" radius chimiro pamudzi wechubhu inofanirwa kunyatsofanana neyechigadzirwa chevatengi, sezvo iyi "R" radius inokanganisa kusimba kwenzvimbo yakakosha yechigadzirwa. Pamamiriro ezvinhu akajairwa, chubhu yakatenderedzwa inofanira kuderedzwa epurasitiki parutivi kutanga, wozoshandura kukosha zvinoenderana neiyo chaiyo deformation, kune hombe chubhu, iyo chubhu chimiro chinogona kugadzirwa seovhari chimiro pamberi.

3, chigadzirwa "U" chimiro chepurasitiki bit deformation

Plastiki ye "U-shape" inodawo kuita nezve 2-3 madhigirii deformation, iyo yepakati nzvimbo ye "U -shape" mbabvu inofanira kuita kucheka zvinhu padivi zvakare (mufananidzo 1). Mushure mekunge zvigadzirwa zvese zvadhirowewa zvakanaka uye wozogadzira iyo "R" radius (zvakare yekufambisa shanduko, dzimwe nguva "R" kuvakwazve kweradius kuchatadza kana nguva yakareba yashandiswa), kana mamwe majometry muvatengi 3D data asina kukanganisa, tinogona chamfer ivo kana vasina kukanganisa zvikamu gungano (vazhinji vatengi vanosarudza iyo yakapinza chimiro kuve chamfered ne "R" radius). Uye zvakare, mamwe ane mukurumbira geometry pachigadzirwa chikuru muviri akakura, rudzi urwu rwekugadziriswa kwechigadzirwa runofanira kubhadhara zvakanyanya parallelism uye perpendicularity (mufananidzo 2).

5, Mhedziso

Pamusoro pane ruzivo rwedu pakugadzira auto air & tank remvura- "deformation zviri nyore" chigadzirwa mold. kupedzisa nhanho iyi zvakanaka, ndinofunga hafu yekubudirira kwekugadzira molds kwaizowanikwa, saka imwe hafu iripi? ndapota ona chikamu chinotevera chechinyorwa chino "Unoziva here kugadzira pre-deformation mold? -kugadzira chikamu" svondo rinouya.
Zvakanaka, vaverengi vanodiwa. Kutenda kwakawanda nenguva yako yekuverenga pano.kutarisira kukuona pachikamu chinotevera!
