Esona sixhobo siphambili sokubumba imveliso yi-hydraulic press.Indima yomatshini wokushicilela we-hydraulic kwinkqubo yokucinezela kukusebenzisa uxinzelelo kwiplastiki ngokusebenzisa i-mold, vula i-mold kwaye ukhuphe imveliso.
Ukubunjwa koxinzelelo kusetyenziswa ikakhulu ukubumba iiplastiki ze-thermosetting.Kwi-thermoplastics, ngenxa yesidingo sokulungiselela i-blank kwangaphambili, kufuneka ifudunyezwe kwaye ipholile ngokunye, ngoko ke umjikelezo wemveliso ude, ukusebenza kakuhle kwemveliso kuphantsi, kwaye ukusetyenziswa kwamandla kukhulu.Ngaphaya koko, iimveliso ezinemilo entsonkothileyo kunye nobukhulu obuchanekileyo azinakucinezelwa.Yiyo ke into eqhelekileyo ekubumbeni inaliti yoqoqosho ngakumbi.
Iumatshini wokubumba woxinzelelo(cofa ngokufutshane) esetyenziselwa ukubumba isishicileli soxinzelelo lwehydraulic.Umthamo wayo ocinezelayo ubonakaliswa ngetoni yegama, ngokubanzi, kukho i-40t ﹑ 630t ﹑ 100t ﹑ 160t ﹑ 200t ﹑ 250t ﹑ 400t ﹑ 500t uthotho loshicilelo.Kukho ngaphezu kwe-1,000 yeetoni zoomatshini bokushicilela abanemigangatho emininzi.Imixholo ephambili yenkcazo yokushicilela ibandakanya i-tonnage yokusebenza, i-ejection tonnage, ubukhulu beplaten bokulungisa ukufa, kunye nemivimbo yepiston yokusebenza kunye nepiston ejection, njl. .Amalungu amancinci angasebenzisa i-cold press (akukho kufudumala, amanzi okupholisa kuphela) ukubunjwa nokupholisa.Sebenzisa umshicileli wokufudumeza ngokukodwa kwiplastiki ye-thermal, enokugcina amandla.
Ngokweqondo le-automation, oomatshini bokushicilela banokwahlulwa babe ngoomatshini bokushicilela bezandla, oomatshini bokushicilela abazenzela ngokwabo, kunye noomatshini abazenzekela ngokupheleleyo.Ngokwenani leengqimba zeplati ecwecwe, inokwahlulwa ibe yi-double-layer kunye ne-multi-layer presses.
Umshicileli we-hydraulic ngumatshini woxinzelelo osebenza ngokuhanjiswa kwe-hydraulic.Xa ucinezela, iplastiki yongezwa kuqala kwi-mold evulekileyo.Emva koko yondla ioli yoxinzelelo kwi-cylinder esebenzayo.Ukukhokelwa yikholomu, ipiston kunye ne-beam ehambayo ihlehla (okanye phezulu) ukuvala ukungunda.Ekugqibeleni, amandla aveliswa ngumshicileli we-hydraulic adluliselwa kwi-mold kwaye asebenze kwiplastiki.
Iplastiki ngaphakathi kokungunda iyanyibilika kwaye ithambile phantsi kwesenzo sobushushu.Isikhunta sizaliswe ngoxinzelelo oluvela kwi-hydraulic press kwaye ukusabela kweekhemikhali kwenzeka.Ukuze ukhuphe umswakama kunye nezinye izinto eziguquguqukayo eziveliswa ngexesha lokuphendula kwe-condensation yeeplastiki kunye nokuqinisekisa umgangatho wemveliso, kuyimfuneko ukwenza uxinzelelo kunye nokukhupha.Yandisa ngokukhawuleza kwaye ugcine.Ngeli xesha, i-resin kwiplastiki iyaqhubeka ifumana iikhemikhali.Emva kwexesha elithile, i-insoluble kunye ne-infusible hard state state yenziwa, kwaye ukubunjwa kokuqina kugqityiwe.Isikhunta sivulwa ngokukhawuleza, kwaye imveliso ikhutshwe kwi-mold.Emva kokuba ukungunda kucociwe, umjikelo olandelayo wemveliso ungaqhubeka.
Inokubonwa kule nkqubo ingentla ukuba ubushushu, uxinzelelo, kunye nexesha ziimeko ezibalulekileyo zokubumba ucinezelo.Ukuze kuphuculwe imveliso yomatshini kunye nokhuseleko kunye nokuthembeka komsebenzi, isantya sokusebenza somatshini siyinto ebalulekileyo engenakunakwa.Ke ngoko, umatshini wokushicilela owenziwe ngeplastiki osetyenziselwa ukucinezela kufuneka ube nako ukuhlangabezana nezi mfuno zingundoqo zilandelayo:
① Uxinzelelo olucinezelayo kufuneka lwanele kwaye luhlengahlengiswe, kwaye luyafuneka ukufikelela kunye nokugcina uxinzelelo olumiselwe kwangaphambili ngexesha elithile.
② Umqadi oshukumayo we-hydraulic press unokumisa kwaye ubuyele kuyo nayiphi na indawo kwi-stroke.Oku kubaluleke kakhulu xa ufaka iimolds, ukucofa kwangaphambili, ukutshaja ibhetshi, okanye ukusilela.
③ Umqadi oshukumayo we-hydraulic press unokulawula isantya kwaye usebenzise uxinzelelo lokusebenza nakweyiphi na indawo kwi-stroke.Ukuhlangabezana neemfuno zokubumba ezinobude obuhlukeneyo.
Umbhobho oshukumayo we-hydraulic press kufuneka ube nesantya esikhawulezayo kwi-stroke engenanto ngaphambi kokuba i-mold yendoda ichukumise iplastiki, ukwenzela ukuba unciphise umjikelezo wokucinezela, uphucule imveliso yomatshini kwaye ugweme ukunciphisa okanye ukuqina kokuhamba kweplastiki.Xa umngundo oyindoda uchukumisa iplastiki, isantya sokuvala isikhunta kufuneka sithotywe.Ngaphandle koko, i-mold okanye ifake ingonakaliswa okanye i-powder ingahlanjwa ngaphandle kwe-female mold.Ngelo xesha, ukucotha isantya kunokususa ngokupheleleyo umoya kwi-mold.
