Ukubunjwa kokuvuthela okungenanto kukwenziwa kwe-extrusion okanye ukubunjwa kwenaliti efunyenwe yi-billet yeplastiki enyibilikayo kwiintlobo ezahlukeneyo ze-abrasive, i-abrasive evaliweyo, kwi-billet ngokokunyanzeliswa komoya, ukuze ihlangane nodonga lwe-abrasive, emva kokupholisa. ubugcisa bokungunda kunye nomngxuma.Ingasetyenziselwa ukuveliswa kweoyile etyiwayo, iziselo, iziselo, i-seasonings, ubisi kunye nezinye izinto zokupakisha ukutya ngeebhotile zeplastiki, iindidi ze-annular, isikwere, ezibunjiweyo kunye nemigqomo ye-doorknob, iinkonkxa kunye nobunye ubugcisa obungenanto.
Ukubumba ukuvuthela okungenanto kukuguqulwa kweplastiki yeplastiki engenanto ebekwe kwisixhobo sokusila, ukunyanzeliswa komoya kwindawo engenanto, ukuyivuthela, yenze ibe kufutshane nodonga lomngxuma wokungunda, emva kokupholisa ukufumana imilo ethile yeplastiki engenanto imveliso kunye nokucubungula. .Ngokwendlela yokubumba ayifani, inokwahlulwa ngeendlela ezine.
1, ukubumba ivuthelo extrusion
I-1 - Intloko yomatshini we-Extrusion 2 - i-blow molding die 3 - i-tubular billet 4 - ibhoiler yoxinzelelo lomoya vuthela ityhubhu 5 - iinxalenye zeplastiki
I-extruder yokuqala yakhupha i-tubular billet;Khipha icandelo lokugqibezela umbhobho wokugaya kwaye ulibeke kwisixhobo sokusila ngelixa lishushu, vala amacala asekhohlo nasekunene kwelinye uhlobo lokudibanisa olungenanto lwesixhobo sokugaya esivulekileyo;
Emva koko kwi-concave bafe kuxinzelelo lomoya, ukuze i-billet ivuthe kwaye ifakwe kudonga lwangaphakathi lwetafile engundoqo ye-die;
Ekugqibeleni, emva kokugcinwa koxinzelelo, ifriji kunye nokwenza, kunokususa ukunyanzeliswa komoya kunye nokubumba ukususa iindawo zeplastiki.
I-Extrusion blow blowing mold design ilula, utyalo-mali lweprojekthi luncinci, umsebenzi wokwenyani ulula kakhulu, ulungele ukubumba umngxuma weplastiki.I-Extrusion blow blown iziphene zokubumba akulula ukuqina kodonga olulinganayo, iinxalenye zeplastiki kufuneka ziqwalaselwe emva kokususwa kwe-burr.
2, ukubumba ukuvuthela ngesitofu
1 — I-injector nozzle 2 — Uhlobo lwenaliti alunalutho 3 — isiseko sokungunda esinomgongxo (core) 4 — Isifudumezi sombane 5 — ukubumba ukubumba 6 — iinxalenye zeplastiki
Isitofu sokuqala sokungunda kumatshini wokutofa ukwenza uhlobo olungenanto lwembonakalo lungenanto;
Emva koko i-core kunye ne-billet ihanjiswe kwi-mold mold mold, i-core is hollow kwaye udonga lwangaphakathi luqulethe i-microporous plate;
Emva koko, i-mold ivaliwe kwaye igxininiswe kumbhobho we-core shaft emoyeni, ukwenzela ukuba i-blank ivuthelwe kwaye ifakwe eludongeni lwangaphakathi lwe-concave mold surface ye-abrasive tool;
Ekugqibeleni, emva kokugcinwa koxinzelelo, ifriji kunye nokwenza, kunokususa ukunyanzeliswa komoya kunye nokubumba ukususa iindawo zeplastiki.
Inzuzo yokubumba isitofu kukuba ubukhulu bodonga lwamacandelo eplastiki bulungelelaniswe kakuhle ngaphandle kwe-flying edge, ngaphandle kwemveliso kunye nokucubungula.Ngenxa yohlobo lwenaliti spectrum engenanto, ngoko akukho joint ezantsi kumalungu eplastiki, amandla aphezulu compressive, imveliso ephezulu kunye nokusebenza ngempumelelo, kodwa utyalo-mali lweprojekthi koomatshini kunye nezixhobo kunye nezixhobo abrasive inkulu kakhulu, ingakumbi kwibhetshi. ukuveliswa kwamalungu eplastiki amancinci naphakathi.
3, isitofu ukolula vuthela ukubumba
1 — I-injector nozzle 2 — injection mold 3 — stretch mandrel (boiler blow tube) 4 — vuthela ukubumba 5 — iinxalenye zeplastiki
Isitofu eyolula ukuvuthela ivuthelo yindlela imveliso kunye processing ukuba inaliti yokubumba spectral blank ifudunyezwe ubushushu obufanelekileyo ngaphantsi kwendawo isisombululo kwaye ibekwe kwisixhobo abrasive.Intonga yokwandiswa kuqala iqhutywe ngokunwebeka kwe-radial kwaye emva koko iye kwi-air compression blow blowing.
Emva kokwelula isibetho esibunjiweyo samalungu eplastiki okucaca kwayo, amandla okumelana nempembelelo, amandla angaphezulu, ukuqina okugoba kunye neempawu zokuxhathisa umphunga zihlala ziphuculwa kakhulu.Isitofu sivuthela isivuthelo sento eyona nto iqhelekileyo ziibhotile zamanzi ezimbiwa zepolyester.Isitofu sokuvuthela isivuthelo sinokwahlulwa ngendlela yebillet eshushu kunye nendlela ebandayo yebillet iindlela ezimbini zokubumba.
Inaliti yokuqala yokubumba i-spectral engenanto;Hambisa ibhilethi kwindawo yokubumba ukolula kunye nokuvuthela ukuze wenze ukolula kunye nokuvuthela ukubumba;Emva kokugcinwa koxinzelelo, ifriji ephuma kwi-mold isuse iindawo zeplastiki.
Olu hlobo lwendlela yokubumba igcina ukufudumeza kwakhona kwe-billet ebandayo kwaye igcina amandla.Ukongeza, inkqubo ye-billet kunye nokubunjwa kwe-stretch blow kuqhutyelwa kumatshini ofanayo kunye nezixhobo, ezithatha indawo encinci, ilungele ukuphuhliswa okuqhubekayo kwemveliso kunye nokuveliswa, kwaye inezinga eliphezulu lobuchwepheshe obuzenzekelayo.
Inaliti ebandayo yebillet eyolula ivuthela ukubumba kukutofwa kobushushu obulungileyo bebillet kwiqondo lobushushu obufanelekileyo kwaye emva koko uyibeke kubumba lokubumba ukubetha ukwenza ukubumba ukubumba.Xa ukhetha indlela yokwenza i-billet ebandayo, inaliti ye-billet kunye ne-stretch blow blowing yamalungu eplastiki aqhutyelwa koomatshini kunye nezixhobo ezahlukeneyo ngokulandelelana.Ngaphambi kokubunjwa kokubetha, ukwenzela ukuhlawulela ukushisa okukhutshwe yifriji ye-billet, ukufudumeza okwesibini kufuneka kuqhutywe ukuze kuqinisekiswe ukubunjwa kwe-billet.
Iiplastiki ezi-4 zokubumba ukuvuthela
Iphepha leplastiki elivuthela ukubumba inaliti yokubumba okanye i-extrusion yokubumba iplastiki yokufudumeza, yenza ukuba ithambe, ibe ngumbumba we-concave, itshixiwe embindini wepleyiti yeplastiki kuxinzelelo lomoya kwaye wenze iindawo zeplastiki ezingenanto.
