Chiitiko chekuti madziro emadziro ehukuru hwakafanana extruded chigadzirwa haana kuenzana mune imwechete muchinjikwa chikamu kana longitudinal nhungamiro inonzi isina kuenzana madziro ukobvu.
Zvinonyanya kukonzera kusaenzana kwemadziro ukobvu
1) Iyo mold dhizaini haina musoro, kana gungano rekushandisa harina kunaka. 2) The extrusion barrel uye extrusion tsono haisi pamutsetse wakafanana wepakati, zvichiita kuti eccentricity. 3) Iyo yemukati yemukati ye extrusion barrel yakapfekwa zvakanyanya, uye mold haigone kusimbiswa zvakasimba, zvichikonzera eccentricity. 4) Ukobvu hwemadziro eingot blank pachayo hauna kuenzana, uye haigone kubviswa mushure mekutanga uye yechipiri extrusions. Ukobvu hwemadziro eiyo rough material hauna kuenzana mushure meextrusion, uye hahubviswe mushure mekukunguruka uye kutambanudza. 5) Mafuta ekuzora anoshandiswa zvisina kuenzana, zvichikonzera kusaenzana kwesimbi kuyerera.
Nzira dzekudzivirira
1) Gadzirisa chishandiso uye kufa dhizaini nekugadzira, uye zvine musoro kuunganidza uye kugadzirisa 2) Rongedza pakati peiyo extruder uye extrusion chishandiso uye kufa 3)
Sarudza vanokwanisa billet 4) Zvinonzwisisika kudzora maitiro parameters akadai extrusion tembiricha uye extrusion kumhanya.
25. Kuwedzera (kufanana)
Kukanganisika kwemativi maviri ezvigadzirwa zveprofile zvakaburitswa senge groove-shaped uye I-shaped zvigadzirwa zvinotsvedza kunze zvinonzi flaring, uye kukanganisa kwekutsvedza mukati kunonzi paralleling.
Zvikonzero zvikuru zvekuwedzera (parallel)
1) Kusaenzana kwesimbi kuyerera mwero we "makumbo" maviri (kana "gumbo" rimwe) remugero kana dhiri-senge chimiro kana I-yakaita chimiro 2) Kusaenzana kuyerera kwebhanhire rekushanda pamativi ese echigero chepasi ndiro 3) Kusatendeka kutambanudza uye kururamisa muchina 4) Kusakwana kutonhora kweiyo online mhinduro kurapwa mushure mekunge chigadzirwa chinosiya gomba rekufa.
Nzira dzekudzivirira
1) Nyatsodzora kumhanya kweextrusion uye tembiricha yeextrusion 2) Iva nechokwadi chekufanana kwekutonhora 3) Kunyatso gadzira uye kugadzira mold 4) Nyatsodzora tembiricha yeextrusion nekumhanya, uye nekuisa nenzira kwayo mold.
26. Kutwasanura mamakisi
Iyo spiral mitsetse inogadzirwa kana iyo extruded chigadzirwa ichitwasanudzwa nepamusoro roller inonzi kutwasanuka mamakisi. Zvese zvigadzirwa zvakatwasanudzwa nepamusoro roller hazvigone kudzivirira kutwasuka mamakisi.
Zvikonzero zvikuru zvekutwasanura mamakisi
1) Kune mitsara pamusoro pekugadzirisa roller surface 2) Kutenderera kwechigadzirwa kwakanyanyisa 3) Kudzvinyirira kwakanyanyisa 4) Iko kona yerori inogadzirisa yakakura zvikuru 5) Chigadzirwa chine ovality yakakura.
Nzira dzekudzivirira
Tora matanho akakodzera kugadzirisa maererano nezvikonzero.
27. Stop marks, momentary marks, bite marks
yechigadzirwa perpendicular kune extrusion direction inogadzirwa panguva ye extrusion process inonzi mavanga ekurumwa kana mavanga epakarepo (anowanzozivikanwa se "enhema kupaka mamaki").
Munguva yeextrusion, izvo zvakasungirirwa zvakasungirirwa pamusoro pebhanhire rekushanda zvichabva zvadonha uye zvinonamatira kumusoro kwechigadzirwa chakawedzerwa kuita mapatani. Mitsetse yakatwasuka pabhandi rekushanda inoonekwa kana extrusion yamira inonzi parking marks; mitsetse yakatwasuka inoonekwa panguva yeextrusion process inodaidzwa pakarepo mavanga kana bite marks, izvo zvinozoita ruzha panguva yeextrusion.
Chikonzero chikuru chekumisa mamakisi, mavanga echinguvana, uye mavanga ekuruma
1) Kupisa kwekupisa kweingot hakuna kuenzana kana iyo extrusion kumhanya uye kudzvanywa kunoshanduka kamwe kamwe. 2) Chikamu chikuru che mold haina kugadzirwa zvakanaka kana kugadzirwa kana kuunganidzwa zvisina kuenzana kana nemapundu. 3) Pane simba rekunze perpendicular kune extrusion direction. 4) Iyo extruder inomhanya isina kugadzikana uye kune zvinokambaira.
Nzira dzekudzivirira
1) Kupisa kwakanyanya, kunonoka kumhanya, yunifomu extrusion, uye chengetedza extrusion pressure yakagadzikana 2) Dzivirira ekunze mauto perpendicular kune extrusion gwara kubva pakuita pane chigadzirwa 3) Zvinonzwisisika gadzira chishandiso uye mold, uye sarudza nemazvo zvinhu, saizi, simba uye kuoma kwe mold.
28. Inner surface abrasion
Iyo abrasion pamusoro pemukati weiyo chigadzirwa chakaburitswa panguva yeextrusion process inonzi inner surface abrasion.
Zvikonzero zvikuru zvekukwenya kwemukati
1) Pane simbi yakanamatira pane tsono yeextrusion 2) Kupisa kwetsono yeextrusion yakaderera 3) Unhu hwepamusoro hwetsono yeextrusion yakashata uye kune mabhupu uye maronda 4) Kupisa kwekushisa uye kukurumidza hakusi kudzorwa zvakanaka 5) Chiyero che extrusion lubricant hazvina kunaka.
Nzira dzekudzivirira
1) Wedzera tembiricha ye extrusion barrel uye extrusion tsono, uye kudzora tembiricha yeextrusion uye extrusion kumhanya. 2) Simbisa kusefa kwemafuta ekuzora, tarisa kana kutsiva mafuta emarara nguva nenguva, uye shandisa oiri zvakaenzana uye muhuwandu hwakakodzera. 3) Chengetedza pamusoro pezvinhu zvakasvibiswa zvakachena. 4) Dzorera zviumbwa zvisina kukodzera uye tsono dzeextrusion munguva, uye chengetedza nzvimbo ye extrusion mold yakachena uye yakatsetseka.
29. Zvisina kukodzera zvemichina
Kana michina yezvigadzirwa zve extruded, senge hb nehv, ikasasangana nezvinodiwa zvehunyanzvi zviyero kana zvakanyanya kusaenzana, inonzi unqualified mechanical properties.
Zvikonzero zvikuru zvezvisina kukodzera zvema mechanical properties
1) Zvinhu zvikuru zvechigadzirwa chemakemikari ealloy zvinodarika chiyero kana chiyero chisingakoshi 2) Iyo extrusion process kana kupisa kupisa kusinganzwisisike 3) Hunhu hweingot kana zvinhu zvakashata hazvina kunaka 4) Kudzima kwepamhepo hakusviki kudziya kwekudzima kana kukurumidza kutonhora hakuna kukwana: 5) Kusakanganisika kwekugadzira kuchembera.
Nzira dzekudzivirira
1) Kunyatsodzora kuumbwa kwemakemikari maererano nemitemo kana kuumba maitiro anobudirira emukati 2) Shandisa ingots yepamusoro-soro kana zvivharo 3) Gadzirisa nzira ye extrusion 4) Nyatsoshandisa nzira yekudzima hurongwa 5) Nyatsoshandisa maitiro ekukwegura uye kutonga tembiricha yechoto 6) Kuyera kuyera uye Kudzora Tembiricha.
30. Zvimwe zvinhu
Muchidimbu, mushure mekutonga kwakazara, izvo zviri pamusoro makumi matatu zvakakanganisika zvealuminium alloy extruded zvigadzirwa zvakabviswa zvinobudirira, kuwana mhando yepamusoro, goho repamusoro, hupenyu hurefu, uye yakanaka chigadzirwa chepamusoro, zvichiunza simba nebudiriro kune bhizinesi, uye kuwana zvakakosha zvehunyanzvi nehupfumi.
