Isikruru sokuBumba ngokuTofwa ngokuthe ngcembe

Esi sikrufu sokubumba ngesitofu ngokuthe ngcembe senziwe ngentsimbi eyi-38CrMoAla. Imathiriyeli ekrwada ibalulekile ekujikeni ukusebenza, kwaye sikhetha amandla aphezulu kunye nentsimbi engagugiyo kubavelisi bentsimbi abaziwayo baseTshayina abahlangabezana nemigangatho yesizwe (GB/T 3077).

Isikrufu sokubumba isikrufu sikaNanhaiya sikaNanhaiya sibonakalisa icandelo elide lokucinezela, ngokuqhelekileyo libalelwa malunga ne-50% yobude bobude bezikrufu. Ubunzulu be-screw groove buyancipha ngokuthe ngcembe ukusuka kwicandelo lokutyisa ukuya kwicandelo lokulinganisa, liqinisekisa ukuhanjiswa kweplastiki egudileyo, ukunyanzeliswa, kunye neplastiki. Ukuguqulwa kwamandla ngexesha leplastiki kuthambile, kwaye umphumo wokucheba kwiplastiki ngaphakathi kwesikrufu uyanda ngokuthe ngcembe, okwenza ukuba inkqubo yeplastiki igqitywe phantsi kweemeko ezinobunono.  

I-Nanhaiya yokubumba imigqomo ye-screw kaNanhaiya ngokuthe ngcembe iye yadlula kwi-R&D emininzi kunye nophuculo kwaye ngoku idityaniswe kwimigca yemveliso eyahlukeneyo yabavelisi, iphumeza ukusebenza komgangatho wobugcisa. Sinikezela ngewaranti yeminyaka eyi-1-2, kuxhomekeke kumlinganiselo othile wokongezwa kwezinto. Imigqomo ye-Nanhaiya ingena kwinkqubo ye-nitriding, kunye ne-0.8 ~ 2m engqindilili ye-nickel-tungsten alloy alloy spray-welded kwiindawo ezithandwa kakhulu. Oku kwandisa ukuqina komphezulu we-barrel yi-HRC55 ~ 62, ukunyusa ukuxhathisa ukunxiba ngamaxesha angama-2-3.

Uphawu kunye nesicelo

Isikrufu sokubumba sikaNanhaiya ngokuthe ngcembe, kunye necandelo laso elide lokucinezela, sifezekisa "iplastiki ethambileyo" yeeplastiki ze-amorphous kunye nobushushu. Ngokufudumeza okucothayo kunye nokucheba okuqhubekayo, kuthintela ukuthotywa kwemathiriyeli ngelixa iqinisekisa ukunyibilika okufanayo, iyenza ifaneleke ngakumbi izicelo ezifuna uzinzo oluphezulu lweplastiki. Icandelo lokucinezela ngokuqhelekileyo libalelwa kwi-40% -60% yobude obupheleleyo be-screw, ixesha elide kakhulu kunezikhonkwane ezikhawulezayo (kuphela i-5% -15%), inika indawo eyaneleyo yenguqu yezinto. Ukusuka kwi-groove enzulu yecandelo lokutya ukuya kwi-groove enzulu yecandelo lokulinganisa, ubunzulu buyancipha ngokucothayo kwaye ngokuqhubekayo, kungabikho manqaku acacileyo "okutshintsha ngokukhawuleza", ngaloo ndlela kuthintela ukunyanzeliswa okukhulu kwezinto. Amacandelo okutya kunye nemitha yokulinganisa ahamba ngokungenamthungo ngokusebenzisa icandelo loxinzelelo olude, ukudala ulwakhiwo oluqhubekayo lwe-screw groove kunye nokuthintela ukuqokelelana kwendawo okanye utshintsho olukhawulezayo loxinzelelo ngexesha lokuhambisa izinto.

I-Gradient injection molding screws ifanelekile kwi-polyvinyl chloride eqinile (PVC), i-polystyrene (PS), i-polycarbonate (i-PC), i-polysulfone (i-PSU), kunye ne-resin ye-ABS. Ezi plastiki mhlawumbi zinezinga elibanzi lobushushu obuthambileyo (umzekelo, i-PVC, malunga ne-80-160 ° C) okanye ukuzinza okungahambi kakuhle kwe-thermal (umzekelo, i-PC, ejongene nokuthotywa kwamaqondo okushisa angaphezu kwe-300 ° C), efuna indawo epholileyo yeplastiki.

Iinkcukacha zeMveliso

Ubushushu obuphezulu, ukuchaneka komatshini, kunye neenkqubo ze-nitriding ziqinisekisa ukusebenza okubanzi kwamacandelo aphambili.

Iindawo ezinobungozi ze-screw kunye ne-barrel ziqiniswa nge-nickel-tungsten alloy layer, ukufikelela kwi-0.8-2.0mm umaleko obunzima kunye nokuphucula kakhulu ukuxhathisa ukunxiba.
