Xa usiva 'intsimbi yokubumba inaliti yeplastiki', umfanekiso ongoko nangoko ukholisa ukuba yintsimbi elula efakwe kwiplastiki. Kodwa kulapho ingcamango yokuqala ephosakeleyo ilele. Ayisiyonto nje yokubeka iqhekeza lesinyithi kwimold kunye nokudubula iplastiki ngeenxa zonke. Umceli mngeni wokwenene, kwaye apho uninzi lweeprojekthi zikhubeka, kukulawula ukwandiswa kwe-thermal eyahlukileyo kunye nokuphumeza ibhondi ehlala phantsi koxinzelelo, hayi nje ibukeka ilungile kwisampulu. Ndibone uyilo oluninzi lusilela kuba luyithathe njengengcinga yasemva.
Ucelomngeni Olungundoqo: NguMtshato, Akunjalo
Umba osisiseko lujongano. Iikhontrakthi zentsimbi malunga ne-0.000006 nge-°F nganye, ngelixa iplastiki eqhelekileyo efana nenayiloni inokosuleleka ngokuphindwe kalishumi kwelo zinga. Ukuba uyila nje ufakelo olugobileyo oluthe tye kwaye ulubumbe ngaphakathi, iplastiki iya kucutheka kuyo, ngokuqinisekileyo. Kodwa ngaba iya kubamba phantsi kwebhayisekile eshushu? Mhlawumbi akunjalo. Uxinzelelo lunokubangela ukuqhekeka okanye, okubi ngakumbi, ukulahleka kancinci kwamandla etorque ukuba kufakwe umsonto. Awujoyini nje izixhobo; utshata nokuziphatha kwabo.
Kulapho amava avela kwezinye iinkqubo ebaluleka kakhulu. Jonga inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY). Ngemvelaphi yabo yeminyaka engama-30 utyalo mali kwaye CNC Machining yeentsimbi kunye ne-alloys ekhethekileyo, baqonda isinyithi. Olo lwazi lunzulu lwemathiriyeli lubalulekile xa uchaza isihlomelo. Ukukhethwa kwe-alloy, ukugqiba kwayo phezulu, kunye nembali yayo ye-thermal evela kwi-casting okanye inkqubo yomatshini ichaphazela ibhondi yokugqibela. Isifakelo asiyonxalenye yempahla yorhwebo; imiba yayo yangaphambili.
Umzekelo, sakha sasebenzisa umgangatho we-304 wokufaka i-stainless yendlu eya kubona ukuguquka kobushushu ngaphandle. Iplastiki yayiyiPBT ezaliswe yiglasi. Iibhetshi zokuqala ziphumelele iimvavanyo zokukhupha. Kodwa emva kwe-500 ye-thermal cycles, indlu yaphuhliswa ukuqhekeka kweenwele ngeenxa zonke ezifakiweyo. Ukusilela kwakungekho ekubumbeni; bekukudityaniswa kwezinto kunye noyilo lweempawu zokugcinwa kwesifakelo. Kwafuneka sibuyele umva, sitshintshele kwi-insert enejiyometri enobundlongondlongo, i-undercut ye-undercut eyenziwe ngomatshini ukusuka kwinqanaba elahlukileyo, kwaye siyifudumeze kubushushu obuthile ngaphambi kokubunjwa. Umahluko wawubusuku nemini.
Inkqubo Nuances: UMtyholi kwiiNkcukacha
I-automation ivakala imnandi de ujongane ne-microscopic burrs. Elinye lawona manyathelo adinayo, kodwa abaluleke kakhulu, kukulungiselela nokuphatha. Ukuba ukhangela izinto ezifakwayo kumatshini ochanekileyo onje nge-QSY (uyakwazi ukubona iphothifoliyo yabo https://www.tsingtaocnc.com), ufumana iinxalenye ezinonyamezelo oluhambelanayo. Kodwa nangona kunjalo, inkqubo yokuhlawula imali ayixoxiswana. Ibhula encinci inokusebenza njengesigxininisi soxinzelelo, iqalise ukuqhekeka kwiplastiki njengoko iphola kwaye incipha.
Emva koko kukho ukubekwa. Ukulayisha ngesandla kunempazamo kwaye kuyacotha. Iingalo zerobhothi zingcono, kodwa zifuna ukulungiswa okugqibeleleyo kubumba. I-mold ngokwayo idinga i-cavities echanekileyo kwaye isoloko idinga ulawulo lwe-thermal-ngamanye amaxesha kufuneka ushushu i-pocket yokufaka, ngamanye amaxesha kufuneka upholise ngokukhawuleza, kuxhomekeke kwiplastiki. Akukho mgaqo omnye. Ndikhumbula iprojekthi apho kwafuneka sisebenzise izifudumezi ze-induction zasekhaya ezakhiwe kwi-mold ukuzisa ukufakwa kwe-aluminium kwi-120 ° C ngaphambi kokuba i-injection ithintele imigca ye-weld kunye nokuqinisekisa ukuhamba malunga neempawu ezinzima.
Kwaye flash. Owu, ilitha. Ukuba into efakiweyo ayihlalanga ngokugqibeleleyo, okanye ukuba i-clamping force ayonelanga, iplastiki iya kungena kwesona sikhewu sincinci. Oku kudala ilitha ekunzima ngokumangalisayo ukulisusa kuba lijijelwe ngentsimbi. Ihlala ifuna umsebenzi wesibini womatshini, oyoyisa injongo yenkqubo yokwakheka komnatha. Lo ngumbulali weendleko ezithe cwaka ukuba izicatshulwa ezininzi ziphosakele ngokupheleleyo.
Ukukhethwa kwezinto: I-Symphony, hayi iSolo
Awukwazi ukuthetha ngenkqubo ngaphandle kokuthetha ngeplastiki. Kungumgibe oqhelekileyo ukukhetha iplastiki yecandelo eliphambili lomsebenzi kwaye unethemba lokuba ukufakwa kusebenza. Kufuneka ibe sisigqibo esidibeneyo. I-amorphous resins njenge-ABS okanye i-PC bond ngokwahlukileyo kune-semi-crystalline efana ne-POM okanye i-PA. Iiglasi okanye izihluzi zeeminerali zonyusa ukuqina kodwa zinciphisa ukucinezeleka-ukungaphumeleli, zenza ujongano lube brittle.
Kulapho ubuchwephesha bentsimbi obuvela kwiqabane buba bubalulekile. Umsebenzi we-QSY kunye cobalt-based kwaye ialloys esekwe nickel kuxinzelelo oluphezulu, izicelo zobushushu obuphezulu zibanika ukuqonda okungaphakathi kwendlela isinyithi eziziphatha ngayo phantsi komqobo. Xa befaka umatshini wokufaka, bacinga ngesakhiwo senkozo, uxinzelelo olushiyekileyo olusuka ekusikeni, kunye nendlela loo ndawo iya kusebenzisana ngayo nepolima etyhidiweyo equkuqela kuxinzelelo oluphezulu. Leyo asiyongcinga eqhelekileyo yevenkile yoomatshini ngokubanzi.
Sasinecandelo lesixhobo sonyango esasifuna ukwenziwa ngokuzenzekela. Iplastiki yayiyiPEEK yobushushu obuphezulu. Ukhetho olucacileyo lokufakela yayiyintsimbi ecoliweyo eyenziwe ngoomatshini. Kodwa ukwenziwa komatshini okusemgangathweni kushiye iiyantlukwano ze-micro-surface ezidale iindawo ezibuthathaka. Ukusebenza neqela eliwuqondayo wonke umjikelo wobomi, sigqibe kwelokuba sichaze ukuthungwa komphezulu obekwe ngokukodwa kwisifakelo, esathi sagqithiswa. Amandla ebhondi emva kwemijikelo yokuvala inzala ayengaphezulu kwama-40% ngaphezulu. Oko kwavela kwincoko enzulu, yentsebenziswano yezinto eziphathekayo, kungekhona nje ukuncokola.
Xa Ingalunganga: Ukufunda kwiintsilelo
Ayizizo zonke iiprojekthi eziyimpumelelo yeencwadi. Elinye lawona mava athobekayo yayikukuba nendlu enkulu, ecekethekileyo enodonga olunezifakelo zobhedu ezingaphezu kwama-50 kwizihlanganisi. Uyilo lwalujongeka kakuhle ephepheni. Sayibumba. Amalungu aphuma ngokubonakalayo agqibelele. Kodwa ngexesha lovavanyo lokulahla, izindlu azizange ziqhekeke-iplastiki ejikeleze isiqingatha sokufakwa kwalula ukuyiyeka. Izinto ezifakelweyo zasonta ngokukhululekileyo ngaphakathi kwiipokotho zazo.
Uvavanyo lokufa luveze izinto ezimbini. Okokuqala, izinto zobhedu zazinendawo egudileyo, ekhazimlisiweyo ukusuka ekuweni, nto leyo eyayibangela ukuba iplastiki ikwazi ukubambelela ngoomatshini. Okwesibini, nangaphezulu, ipateni yokuhamba kweplastiki idale imigca ye-weld ebuthathaka ngokuthe ngqo emva kokufaka nganye ngenxa yendlela yokufaka ephazamisa ukuhamba. Isisombululo asikokutshintsha nje ukuthungwa kwe-insert. Kuye kwafuneka sihlengahlengise isango kunye nenkqubo yembaleki ukuze siqinisekise ukuba i-flow front iya kudibaniswa ngaphambi kokudibana nokufakwayo, hayi ngeenxa zonke kuyo. Yongeza iindleko kunye nobunzima ekubumbeni, kodwa yayikuphela kwendlela.
Enye imowudi yokungaphumeleli yakudala kukuhlwa. Ukuba usebenzisa isifakelo sesinyithi esingafaniyo kwindawo engabona ukufuma okanye ukungcoliseka kwe-ionic, ukubola kwegalvanic kunokwenzeka kwi-interface, ukuthoba kancinci ibhondi. Ndiyibonile le nto kwi-automotive electronics. Kukusilela okuthatha iinyanga okanye iminyaka ukubonakala. Ngoku, sihlala siqwalasela okusingqongileyo kwaye ngamanye amaxesha sichaza igesi yeplatin okanye i-alloys ehambelanayo, nokuba ixabisa ngaphezulu.
Owona Mfanekiso Mkhulu: Kutheni Uyifanele Ingxaki
Ngoko kutheni uzikhathaza ngako konke oku kuntsonkotha? Kuba xa yenziwe kakuhle, faka intsimbi yokubumba inaliti yeplastiki yenza iindawo ezingenakwenzeka nangayiphi na enye indlela. Ufumana amandla asekuhlaleni, ukuhanjiswa, okanye ukunxitywa kwentsimbi kudityaniswe nenkululeko yoyilo, ukukhaphukhaphu, kunye neendleko-zokusebenza zokubumba iplastiki. Ivumela iindibano ezidibeneyo, inciphise inani leenxalenye, kwaye ihlala iphelisa imisebenzi yendibano yesibini efana nokufakwa kocinezelo okanye ukufakwa kwe-ultrasonic.
Yinkqubo efuna intlonipho kuzo zombini izinto zenzululwazi. Awunakuba yingcaphephe yeplastiki okanye ingcali yesinyithi. Kufuneka ube nobuchule kuzo zombini, okanye usebenze namaqabane akhoyo. Ifemu efana ne-QSY, ibhuloho iqokobhe ngundo ukuphosa kwiifom zetsimbi ezinzima kunye CNC Machining ukuchaneka, izisa ubunzulu obubalulekileyo becala lentsimbi etafileni. Imbali yabo ende ithetha ukuba babonile ukuba izinto zabo zentsimbi zisilela njani ebaleni, nto leyo eyazisa uyilo olungcono lokufaka kwasekuqaleni.
Ekugqibeleni, ukubumba okuyimpumelelo kwesinyithi kungokukulindela incoko phakathi kwezinto ezimbini kubomi bonke bemveliso. Asiyonkqubo ecocekileyo, yethiyori. Kumdaka, kunamandla, kwaye kugcwele izigqibo ezincinci ezineziphumo ezinkulu. Kodwa ukuyilungisa-kulapho ulwaneliseko lokwenyani lobunjineli lulele. Inxalenye isebenza nje, ngokuthula nangokuthembekileyo, kwaye yeyona njongo iphambili.
