I-1) Ibhanti yomsebenzi we-mold ayilungiswanga ngokufanelekileyo kwaye ukulungiswa kwesikhunta akukho ndawo. 2) Ubungakanani bomngxuma we-shunt okanye igumbi langaphambili alifanelekanga. Ukutsala okanye amandla okwandisa iphrofayili kwindawo yokudibanisa ibangela utshintsho oluncinci kwindiza. I-3) Inkqubo yokupholisa ayilingani, kwaye inxalenye enodonga olungqingqwa okanye inxalenye ye-intersection Izinga lokupholisa licothayo, okubangela ukuba kubekho amanqanaba ahlukeneyo okunciphisa kunye nokuguqulwa kwendiza ngexesha lenkqubo yokupholisa. 4) Ngenxa yomahluko omkhulu kubunzima, umahluko phakathi kolwakhiwo lwenxalenye engqindilili-engqingqwa okanye indawo yenguqu kunye neyamanye amalungu ayanda.
Iindlela zokuthintela
1) Ukuphucula umgangatho woyilo lokubumba, ukuveliswa kunye nokulungiswa kwesikhunta 2) Qinisekisa izinga lokupholisa elifanayo.
20. Iimpawu zokungcangcazela
Iimpawu zokungcangcazela ziziphene ezithe tyaba zemigca ethe tyaba kumphezulu weemveliso ezikhutshiweyo. Ibonakaliswa yimivimbo ethe tye eqhubekayo yeperiodic kumphezulu wemveliso. Igophe lomgca lihambelana nokumila kwebhanti elisebenzayo lokungunda. Kwiimeko ezinzima, inokubonakala okucacileyo kunye ne-convex.
Oonobangela abaphambili beempawu zokungcangcazela
shaft ishukuma phambili ngenxa yeengxaki zezixhobo, ibangela ukuba isinyithi sishukume xa siphuma emngxunyeni. I-2) Intsimbi iyagubha xa iphuma kwi-mold hole ngenxa yeengxaki zokubumba. I-3) I-pad yokuxhasa i-mold ayifanelekanga, ukuqina kwe-mold kubi, kwaye ukugubha kwenzeka xa uxinzelelo lwe-extrusion luguquguquka.
Iindlela zokuthintela
1) Sebenzisa i-molds efanelekileyo 2) Sebenzisa iipads zokuxhasa ezifanelekileyo xa ufaka i-mold 3) Lungisa izixhobo.
21. Ukubandakanywa Izizathu eziphambili zokubandakanywa
Oonobangela abaphambili beukubandakanywa
Ngenxa yokuba i-blank blank iqulethe i-metal okanye i-non-metal inclusions, ayifumanekanga kwinkqubo yangaphambili kwaye ihlale phezu komhlaba okanye ngaphakathi kwemveliso emva kokukhutshwa.
Iindlela zokuthintela
Ukuqinisa ukuhlolwa kweebhilithi (kubandakanywa nokuhlolwa kwe-ultrasonic) ukukhusela iibhilidi eziqulethe isinyithi okanye i-non-metallic inclusions ekungeneni kwinkqubo yokukhupha.
22. Iimpawu zamanzi
Ukukhanya okumhlophe okukhanyayo okanye okumnyama okumnyama okungaqhelekanga kumgca wamanzi kumphezulu weemveliso kuthiwa ziimpawu zamanzi.

I-1) Uyilo lwe-mold alunangqiqo, okanye i-tooling assembly ayifanelekanga. I-2) I-barrel ye-extrusion kunye nenaliti ye-extrusion ayikho kumgca weziko elifanayo, okubangela ukuba i-eccentricity. I-3) Umgca wangaphakathi we-barrel extrusion ugqitywe kakhulu, kwaye isikhunta asikwazi ukuqiniswa ngokuqinileyo, okubangela ukuba i-eccentricity. 4) Ubunzima bodonga lwe-ingot blank ngokwalo alulingani, kwaye alukwazi ukupheliswa emva kwe-extrusions yokuqala neyesibini. Ubunzima bodonga bezinto ezinqabileyo azilingani emva kokukhutshwa, kwaye abususwanga emva kokuqengqeleka kunye nokwelula. I-5) Ioli yokuthambisa isetyenziswe ngokungafaniyo, okubangelwa ukuhamba kwesinyithi esingalinganiyo.
Iindlela zokuthintela
1) Lungiselela isixhobo kunye noyilo lokufa kunye nokuveliswa, kwaye udibanise ngokufanelekileyo kwaye ulungelelanise i-2) Lungisa iziko le-extruder kunye nesixhobo sokukhupha kwaye ufe 3)
Khetha i-billet efanelekayo 4) Ukulawula ngokufanelekileyo iiparameters zenkqubo ezifana nokushisa kwe-extrusion kunye nesantya sokugqithisa.
25. Ukwandiswa (ngokuhambelanayo)
Isiphene samacala amabini eemveliso zeprofayili ezikhutshiweyo ezifana ne-groove-shaped kunye neemveliso ezimile njenge-I ezithambekele ngaphandle zibizwa ngokuba yi-flaring, kwaye isiphene sokuthambekela ngaphakathi sibizwa ngokuba yi-paralleling.
Abona nobangela baphambili bokwandiswa (ngokuhambelanayo)
I-1) Isantya sokuhamba kwesinyithi esingalinganiyo "yemilenze" emibini (okanye "umlenze" omnye) weprofayili okanye iprofayili efana ne-I-shaped profile okanye i-I-shaped profile 2) Ukungalingani kokuhamba kwebhanti yokusebenza kumacala omabini eplate ephantsi yomkhombe 3 ) Ukwelula okungafanelekanga kunye nomatshini wokulungisa 4) Ukupholisa okungafaniyo konyango lwesisombululo se-intanethi emva kokuba umkhiqizo ushiya umgodi wokufa.
Iindlela zokuthintela
I-1) Lawula ngokungqongqo isantya se-extrusion kunye nokushisa kwe-extrusion 2) Qinisekisa ukufana kokupholisa 3) Ukuyila ngokuchanekileyo kunye nokwenza isikhunta 4) Lawula ngokungqongqo ukushisa kunye nesantya, kwaye ufake ngokuchanekileyo i-mold.
26. Amanqaku olula
Imigca ejikelezayo eveliswayo xa imveliso eyongeziweyo ilungiswa yirola ephezulu ibizwa ngokuba ngamanqaku okuqondisa. Zonke iimveliso ezichanekileyo nge-roller ephezulu azikwazi ukuphepha iimpawu ezichanekileyo.

Thabatha amanyathelo afanelekileyo okuhlengahlengisa ngokwezizathu.
27. Ukuyeka amanqaku, amanqaku ethutyana, amanqaku okuluma
yemveliso perpendicular ukuya ulwalathiso extrusion eveliswe ngexesha lenkqubo extrusion zibizwa ngokuba bite marks okanye instantaneous marks (eyaziwa ngokuba "ziimpawu zokupaka zobuxoki").
Ngexesha lokukhutshwa, iziqhotyoshelo ezinamathele ngokuzinzile kumphezulu webhanti esebenzayo ziya kuwa ngokukhawuleza kwaye zihambelane nomgangatho wemveliso ekhutshiweyo ukwenza iipatheni. Imigca ethe tye kwibhanti yokusebenza ebonakala xa i-extrusion stops ibizwa ngokuba ngamanqaku okupaka; imigca ethe tye ebonakala ngexesha lenkqubo ye-extrusion ibizwa ngokuba ngamanqaku akhawulezayo okanye amanqaku okuluma, okuya kwenza isandi ngexesha le-extrusion.
Oyena nobangela wamanqaku okuyeka, amanqaku omzuzu, kunye namanqaku okuluma
I-1) Ukushisa kweqondo lokushisa kwe-ingot akulingani okanye isantya sokukhupha kunye noxinzelelo lutshintsha ngokukhawuleza. 2) Inxalenye ephambili yesikhunta ayilungiswanga kakuhle okanye yenziwe okanye idityaniswe ngokungafaniyo okanye inezikhewu. 3) Kukho amandla angaphandle e-perpendicular ukuya kwi-extrusion direction. I-4) I-extruder iqhuba ngokungazinzi kwaye kukho izinambuzane.
Iindlela zokuthintela
1) Ubushushu obuphezulu, isantya esicothayo, i-extrusion efanayo, kwaye ugcine uxinzelelo lwe-extrusion luzinzile 2) Thintela amandla angaphandle e-perpendicular ukuya kwinqanaba le-extrusion ekusebenzeni kwimveliso 3) Yila ngokufanelekileyo isixhobo kunye nokubumba, kwaye ukhethe ngokuchanekileyo izinto, ubukhulu, amandla. nokuqina komngundo.
28. Ukuqhawuka komphezulu wangaphakathi
I-abrasion kwindawo yangaphakathi yemveliso ekhutshiweyo ngexesha lenkqubo ye-extrusion ibizwa ngokuba yi-inner surface abrasion.
