I-screw inokuhlangabezana njani nokumelana nokunxiba kunye neemfuno zokusetyenzwa okuphezulu?

Kwintsimi yeplastiki ye-extrusion kunye nenaliti yokubumba, iisikrufu esinyelelona candelo lamandla lilo lonke umgca wemveliso. Idizayinwe kakuhle kwaye yenziwe ngokuchanekileyo, ayibonisi kuphela ukuzinza kwezinto ezihambisayo kunye nomgangatho weplastiki, kodwa ichaphazela ngokuthe ngqo ukuchaneka komgangatho weemveliso ezigqityiweyo kunye nokuqhubekeka kwemveliso. Ukujongana nezixhobo ezintsonkothileyo eziqulathe ifayibha yeglasi, i-calcium carbonate, izihluzi zezimbiwa, kunye nezongezo ezitshatyalaliswayo, ukugcina ukuxhathisa okugqwesileyo kokunxiba kunye nokuchaneka okuzinzileyo kokusetyenzwa kweli candelo liphambili phantsi komthwalo ophakamileyo wexesha elide, ukungqubana okuphezulu kunye nobushushu obuphezulu kuye kwaba lujoliso lobuchwephesha kubaphathi bezixhobo kunye neenjineli zenkqubo.

Ukunxiba kunye nokuGwabala: Izizathu eziphambili eziSekwe kwiDatha yoMveliso

Izinto ezikhokelela ekungaphumelelini kobuso be-screw kwangaphambi kwexesha zihambelana ngokuthe ngqo neempawu zezinto ezicutshungulwayo. Izixhobo ezahlukeneyo zivelisa iindlela ezahlukeneyo zomonakalo kwiI-Screw enye,ifuna izisombululo zokhuseleko ekujoliswe kuzo. Itheyibhile engezantsi ishwankathela iintlobo ezintathu eziqhelekileyo zomonakalo wezinto eziphathekayo kunye nemiphumo yazo:

Kwimveliso yokwenyani, ukunxitywa kwe-abrasive kunye nokubola kweekhemikhali zihlala zitshintshana, ziqhubela phambili ukukhawulezisa ukuwohloka kwesikrufu. Ngoko ke, inkqubo yokukhusela epheleleyo kufuneka yakhiwe kwiinkalo ezintathu: izinto eziphathekayo, unyango lobushushu, kunye nobunjineli bomhlaba.

Iindlela eziPhambili zobuGcisa zokuphucula ukuNxibelela kunye nokuchaneka

Iinkqubo ezingundoqo: ukuKhuselwa okuCwangcisiweyo ukusuka kwiSiseko soNyango lweMpatho ukuya kwiNqaku eliQinisekileyo

Ukufezekisa ukuxhathisa kokunxiba okuphezulu kunye nokuchaneka okuphezulu, abavelisi abaziingcali bahlala bethatha le nkqubo ilandelayo yenkqubo:

• Izinto ezisisiseko zokucima kunye nokuthambisa-Sebenzisa i-38CrMoAlA intsimbi yealloyi, yenza ukucima kunye nobushushu obuphezulu ukuze ufumane ulwakhiwo lwe-sorbite efanayo, ukuphelisa uxinzelelo kunye nokubonelela ngokuqina okuhle.
• Ukusila ngokuchanekileyo-Sebenzisa i-cylindrical ephezulu echanekileyo kunye ne-CNC yokusila intambo ukuqinisekisa ukuchaneka kwejometri yeprofayile yendiza. Ukuthi tye, ukunyamezelwa kwesandi selizwi, kunye noburhabaxa bomphezulu aI-Screw enyezilawulwa kumgangatho we-micron, ukunciphisa ukunyibilika umva kunye nengxabano yendawo.
• Umphezulu we-nitriding– Faka igesi okanye i-ion nitriding ukwenza umaleko omhlophe oyi-0.3–0.6 mm kumphezulu osisijiwu, uphumeze ubulukhuni bomphezulu be-HV900–1100, uphucula kakhulu ukuxhathisa ukunxiba kwe-abrasive ngelixa ugcina ubungqongqo obungundoqo.
• I-Electroplating okanye i-electroless plating-Kwizinto ezonakalisa kakhulu (umzekelo, i-PVC, i-fluoroplastics), yongeza i-chromium eqinile okanye i-nickel umaleko we-nickel phezu komgangatho we-nitrided ukutywina i-micro-pores kunye nokwandisa ukuxhathisa ukubola, ngelixa unciphisa ukuncamathela okunyibilikayo.
• I-dual-alloy spray welding (i-PTA okanye i-laser cladding)-Kwizinto ezirhabaxa kakhulu ezifana nefiber yeglasi, i-calcium carbonate, okanye imathiriyeli esetyenzisiweyo, sebenzisa i-nickel-based okanye i-cobalt-based alloy kwiingcebiso zokubhabha, ukuphumeza ubulukhuni ngaphezu kwe-HRC60. Esi sakhiwo sidityanisiweyo sivumela isikrufu ukuba sigcine umthamo weplastiki ozinzileyo kunye nokukhutshwa okuchanekileyo phantsi kwe-speed-speed extrusion kunye neendawo ezinobungozi.

Ukuchaneka koMatshini kunye neNkqubo yokuTyaniswa: Ukuqinisekisa iPlastiki eFanayo kunye nokuNxibelelana kweMveliso

Ukuchaneka okuphezulu akukhona nje malunga nokunyamezela kwe-screw's dimensional toleranceal, kodwa malunga nokulawula ukukhutshwa phakathi kwe-screw flight diameter yangaphandle kunye nodonga lwangaphakathi lombhobho. Amava abonisa ukuba ukulawula ucoceko phakathi aI-Screw enye kunye ne-barrel ngaphakathi kwe-0.10-0.20 mm (kuxhomekeke kububanzi) kunciphisa kakhulu ukuvuza kwe-melt kunye nokwandisa umkhiqizo othile. Ukongeza, imilinganiselo yejometri ephuculweyo (umlinganiselo woxinzelelo, umlinganiselo we-L / D) ohambelana ne-grooved barrel feed bushings unokufikelela kwi-plasticizing ye-shear ephezulu ngesantya esisezantsi se-screw, ukunciphisa ubushushu bokunyibilika malunga ne-10 ° C, ngaloo ndlela kuphuculwe umgangatho wemveliso kunye nokuzinza kwe-dimensional.

Izisombululo zizonke zeeMeko zokuSebenza eziNgqwirha

Kwiimathiriyeli ezikhethekileyo ezinje ngeplastic composite (WPC), iiplastiki zobunjineli ezizaliswe kakhulu, kunye nemathiriyeli esetyenzisiweyo, abavelisi abakhokelayo baye basuka ekusetyenzweni kwenxalenye elula ukuya kwiinkonzo zobugcisa ezidityanisiweyo ezigubungela “ukhetho lwezinto – uyilo lwenkqubo – emva konyango”.

Ngokomzekelo, i-nylon eyomeleziweyo equlethe ngaphezu kwe-30% ye-fiber yeglasi, i-screw inokuyilwa kunye ne-pitch eguquguqukayo kunye nobunzulu besiteshi esiguquguqukayo, kunye neenguqu ezijikelezileyo kwingcambu yendiza ukunciphisa uxinzelelo loxinzelelo. Idityaniswe ne-dual-alloy spray welding kunye ne-mirror polishing (uburhabaxa be-surface Ra ≤ 0.05 μm), oku kunciphisa ingozi yediphozithi yekhabhoni kwaye iququzelele ukucoca.

Isiphelo: Ixabiso leXesha elide lokuTyalo-mali kwiSikrikri sokuSebenza okuPhezulu

Ngamafutshane, aI-Screw enyeyenziwe ngoyilo oluchanekileyo kunye nonyango olukhuselayo oluninzi alunandisi kakhulu ubomi bayo benkonzo kuphela, kodwa ikwaphucula i-extrusion kunye nenaliti yokubumba amandla okusebenza kakuhle, inciphisa ukuphindaphindwa kokugcinwa, kwaye iqinisekisa ukungaguquguquki komgangatho wemveliso. Xa iinkampani zokulungisa iplastiki zikhetha umenzi onjeZhoushan Nanhaiya Plastic Machinery Co., Ltd.– enetsheyini yenkqubo epheleleyo, izixhobo zomatshini ezichanekileyo, kunye namava abanzi kwishishini – bafumana isiqinisekiso sobugcisa esinye sokuma kwisixhobo sokujiya, unyango lobushushu ukuya kumanqwanqwa angaphezulu, babeka isiseko esiluqilima semveliso ezinzileyo yexesha elide.
