Kushanda Nheyo yeFixed Extrusion Musoro weAluminium Extrusion Machine

Extrusion musoro wealuminium extrusion

The extrusion musoro ndiyo inonyanya kukosha extrusion midziyo inoshandiswa mualuminium extrusion process (Fig 1). Hunhu hwechigadzirwa chakatsikirirwa uye kugadzirwa kwese kweiyo extruder kunoenderana nazvo.

Fig 1 Extrusion musoro mune yakajairwa chishandiso gadziriro yeiyo extrusion maitiro

Fig 2Typical dhizaini ye extrusion musoro: extrusion cake uye extrusion tsvimbo

Fig 3 Yakajairika dhizaini yemusoro weextrusion: dzinde revharuvhu uye keke rekuwedzera

Kuita kwakanaka kwemusoro weextrusion kunoenderana nezvinhu zvakaita se:

Yakazara kurongeka kweiyo extruder

Kugovera kwekushisa kweiyo extrusion barrel

Tembiricha uye zvemuviri zvimiro zvealuminium billet

Kuzora kwakakodzera

Nguva dzose kuchengetedza

Basa remusoro weextrusion

Basa remusoro weextrusion rinoratidzika nyore kwazvo pakutanga kuona. Ichi chikamu chakafanana nekuenderera kweiyo extrusion tsvimbo uye yakagadzirirwa kusundira inopisa uye yakapfava aruminiyamu alloy zvakananga kuburikidza nekufa. The extrusion cake inofanira kuita zvinotevera mabasa:

Tumira kumanikidza kune alloy mune yega yega extrusion kutenderera pasi pemamiriro ekushisa kwakanyanya;

Kurumidza kuwedzera pasi pekumanikidzwa kusvika kumuganhu wakatemerwa (Mufananidzo 4), uchisiya chete chidimbu chitete chealuminium alloy pane sleeve yemudziyo;

Zviri nyore kuparadzanisa kubva kune billet mushure mokunge extrusion yapera;

Usateya chero gasi, rinogona kukuvadza mudziyo wemidziyo kana dummy block pachayo;

Batsira kugadzirisa matambudziko madiki nekurongeka kwemapepanhau;

Kugona kukurumidza kukwidzwa / kudzikiswa padanda rekudhinda.

Izvi zvinofanirwa kuvimbiswa neyakanaka extruder centering. Kutsauka mukufamba kwemusoro weextrusion kubva kune extruder axis kazhinji kunozivikanwa nyore nekusafanana kupfeka, kunoonekwa pazvindori zvekeke reextrusion. Naizvozvo, iyo yekutsikirira inofanira kurongeka zvakanyatsonaka uye nguva nenguva.

Simbi yemusoro weextrusion

Musoro weextrusion ndiyo chikamu chechishandiso cheextrusion chinoiswa pasi pekumanikidza kwakanyanya. Musoro weextrusion wakagadzirwa nesimbi inofa (eg H13 simbi). Usati watanga kudhinda, musoro weextrusion unopisa kune tembiricha inosvika 300 ºС. Izvi zvinowedzera kumira kwesimbi kune zvinopisa zvinopisa uye zvinodzivirira kutsemuka nekuda kwekuvhunduka kwekupisa.

Kupisa kwebillet, mudziyo uye kufa

Billet yakanyanyisa (pamusoro pe500ºC) inoderedza kudzvinyirira kwemusoro weextrusion panguva yeextrusion process. Izvi zvinogona kukonzera kusakwana kwekuwedzera kwemusoro weextrusion, izvo zvinoita kuti simbi yebillet inyinywe mugomba pakati pemusoro weextrusion nemudziyo. Izvi zvinogona kupfupisa hupenyu hwesevhisi yedummy block uye kunyange kutungamira kune yakakosha purasitiki deformation yesimbi yayo nemusoro weextrusion. Mamiriro akafanana anogona kuitika nemidziyo ine nzvimbo dzakasiyana dzekudziya.

Kunamatira kumusoro weextrusion kune billet idambudziko rakakura kwazvo. Mamiriro ezvinhu aya anonyanya kufarirwa nemashizha ekushanda akareba uye zvinyoro zvinyoro. Mhinduro yemazuva ano yedambudziko iri ndeyekushandisa lubricant yakavakirwa pa boron nitride kusvika kumagumo echishandiso.

Kugadziriswa kwemusoro we extrusion

Musoro weextrusion unofanirwa kuongororwa zuva nezuva.

Zvinogoneka aluminium adhesion inotarirwa nekutarisa kwekuona.

Tarisa kufamba kwakasununguka kwetsvimbo uye mhete, pamwe chete nekuvimbika kwekugadzirisa kwese screws.

Iyo keke yeextrusion inofanira kubviswa kubva mukudhinda svondo rega rega uye kucheneswa mufa etching groove.

Panguva yekushanda kwemusoro weextrusion, kuwedzera kwakanyanya kunogona kuitika. Izvo zvinodiwa kudzora kuwedzera uku kusave kwakakura. Kuwedzera kwekuwedzera kwedhayamita yewashi yekumanikidza kuchapfupisa zvakanyanya hupenyu hwayo hwesevhisi.
