Ubushushu
Umlinganiselo wobushushu kunye nolawulo kubaluleke kakhulu ekubumbeni inaliti. Nangona le milinganiselo ilula, uninzi loomatshini bokubumba inaliti abanawo amaqondo obushushu aneleyo okanye iingcingo.
Kuninzi koomatshini besitofu, iqondo lobushushu liviwa yi-thermocouple.
I-thermocouple ngokusisiseko ziintambo ezimbini ezahlukeneyo ezihlanganayo ekugqibeleni. Ukuba isiphelo esinye sishushu kunesinye, umyalezo omncinci wetelegraph uya kuveliswa. Ubushushu obuninzi, umqondiso womelele.
Ulawulo lobushushu
Ii-Thermocouples zikwasetyenziswa ngokubanzi njengezinzwa kwiinkqubo zokulawula ubushushu. Kwisixhobo sokulawula, iqondo lokushisa elifunekayo lisetyenzisiwe, kwaye i-sensor display ifaniswa nobushushu obuveliswe kwindawo yokumisela.
Kwinkqubo elula, xa iqondo lokushisa lifikelela kwindawo emiselweyo, licinyiwe, kwaye amandla abuyele kwakhona xa ukushisa kwehla.
Le nkqubo ibizwa ngokuba yi-on/off control kuba ivuliwe okanye ivaliwe.
Uxinzelelo lwesitofu
Olu xinzelelo olubangela ukuba iplastiki ihambe kwaye inokulinganiswa ngeenzwa kwi-nozzle okanye kumgca we-hydraulic.
Ayinaxabiso elimiselweyo, kwaye kunzima ngakumbi ukuzalisa isikhunta, uxinzelelo lwenaliti luyanda, kwaye kukho ubudlelwane obuthe ngqo phakathi koxinzelelo lomgca wenaliti kunye noxinzelelo lwenaliti.
Uxinzelelo lwenqanaba loku-1 kunye noxinzelelo lwenqanaba lesi-2
Ngethuba lokuzaliswa komjikelezo we-injection, uxinzelelo oluphezulu lwe-injection lunokufuneka ukuze kugcinwe izinga lokutofa kwinqanaba elifunekayo.
Uxinzelelo oluphezulu alusafuneki emva kokuba i-mold izaliswe.
Nangona kunjalo, kwisitofu sokubumba ezinye ze-semi-crystalline thermoplastics (ezifana ne-PA kunye ne-POM), isakhiwo siya kusonakala ngenxa yokutshintsha ngokukhawuleza koxinzelelo, ngoko ngamanye amaxesha akukho mfuneko yokusebenzisa uxinzelelo lwesibini.
Uxinzelelo lokubamba
Ukulwa noxinzelelo lwenaliti, uxinzelelo lwe-clamping kufuneka lusetyenziswe. Esikhundleni sokukhetha ngokuzenzekelayo ixabiso eliphezulu elikhoyo, qwalasela indawo eqikelelweyo kwaye ubale ixabiso elifanelekileyo. Ummandla oqikelelweyo weqhekeza lenaliti yeyona ndawo inkulu ebonwayo ukusuka kwicala lesicelo se-clamping force. Kwiimeko ezininzi zokubumba inaliti, malunga neetoni ezi-2 nge-intshi nganye yesikwere, okanye i-31 yeemegabytes nge-square meter nganye. Nangona kunjalo, eli lixabiso eliphantsi kwaye kufuneka lithathelwe ingqalelo njengomgaqo ongqongqo, kuba emva kokuba i-injection piece inobunzulu, iindonga zecala kufuneka ziqwalaselwe.
Uxinzelelo lwangasemva
Olu luxinzelelo ekufuneka isikrufu senziwe kwaye sigqithiswe phambi kokuba sibuyele umva. Uxinzelelo oluphezulu lwe-back back lunceda ukusabalalisa umbala ofanayo kunye nokunyibilika kweplastiki, kodwa kwangaxeshanye, kwandisa ixesha lokubuya kwe-screw ephakathi, ukunciphisa ubude befiber equlethwe kwiplastiki yokuzalisa, kwaye kwandisa uxinzelelo lokubumba inaliti. umatshini.
Ke ngoko, uxinzelelo olusezantsi ngasemva, lungcono, phantsi kweemeko ezinokuthi lugqithise uxinzelelo lomatshini wokubumba inaliti (i-quota ephezulu) ngama-20%.
Uxinzelelo lombhobho
Uxinzelelo lombhobho luxinzelelo lokudubula emlonyeni. Imalunga noxinzelelo olubangela ukuba iplastiki ihambe. Ayinalo ixabiso elimiselweyo, kodwa inyuka ngobunzima bokuzaliswa kwesikhunta. Kukho ubudlelwane obuthe ngqo phakathi koxinzelelo lombhobho, uxinzelelo lomgca kunye noxinzelelo lwenaliti.
Kumatshini wokutofa ngesijiyu, uxinzelelo lombhobho lumalunga ne-10 % ngaphantsi koxinzelelo lwenaliti. Kumatshini wokubumba inaliti yepiston, ilahleko yoxinzelelo inokufikelela malunga ne-10%. Ilahleko yoxinzelelo ingaba malunga neepesenti ezingama-50 ngomatshini wokubumba inaliti yepiston.
Isantya sokutofa
Oku kubhekiselele kwisantya sokuzaliswa kwe-die xa i-screw isetyenziswe njenge-punch. Izinga eliphezulu lokudubula kufuneka lisetyenziswe ekubunjweni kwenaliti yeemveliso ezinodonga olucekethekileyo, ukwenzela ukuba iglue enyibilikayo igcwalise isikhunta ngokupheleleyo ngaphambi kokuqina ukuvelisa indawo egudileyo. Uthotho lwamazinga okudubula acwangcisiweyo asetyenziselwa ukuphepha iziphene ezifana nenaliti okanye ukubanjwa kwegesi. Inaliti inokuqhutywa kwi-open-loop okanye inkqubo yokulawula i-loop evaliweyo.
Kungakhathaliseki ukuba isantya senaliti esetyenzisiweyo, ixabiso lesantya kufuneka lirekhodwe kwiphepha lerekhodi kunye nexesha le-injection, eli lixesha elifunekayo ukuze isikhunta sifikelele kuxinzelelo lwe-injection yokuqala, njengenxalenye yexesha le-screw propulsion.
