Xa abantu abaninzi besiva 'umatshini weplastiki ochanekileyo', bafanekisela umatshini we-CNC oncwinayo, mhlawumbi igumbi elicocekileyo, kunye neendawo ezibonakala zigqibelele. Lowo ngumfanekiso wentengiso. Inyani, le oyifundayo emva kokuchitha i-PEEK engamakhulu ambalwa eedola okanye ukubukela i-UHMWPE yokunyamezelana okuqinileyo kwiveki emva kokunikezelwa, kukuba ukuchaneka apha kuninzi malunga ne-psychology yezinto eziphathekayo njengoko imalunga nokulinganisa koomatshini. Luthethathethwano phakathi kobungqongqo bemfundiso yokusika isinyithi kunye nemvelo eguquguqukayo, ehlala inomsindo, yeepholima. Iivenkile ezininzi eziqaqambileyo ngentsimbi ziyakhubeka apha, ziphatha iplastiki njengealuminiyam ethambileyo, kulapho iingxaki-kunye nokufunda kokwenyani-ziqala khona.
I-Material yi-First Variable, hayi i-Constant
Awunako ukulayisha nje inkqubo yeplastiki yegeneric. Yonke intsapho yepolymer iziphatha njengeentlobo ezahlukeneyo. Umatshini delrin (POM) liphupha—lizinzile, linokuxelwa kwangaphambili, iichips kakuhle. Ufumana imvakalelo yobuxoki yokhuseleko. Emva koko utshintshela kwi inayiloni okanye i-PTFE, kwaye ngequbuliso ulwa nokufunxa ukufuma kunye nokwandiswa kwe-thermal mid-cut. Inxalenye oyilinganise ngokugqibeleleyo kwibhentshi yomatshini iphumile kwi-spec kwiyure kamva. Ndiyifunde le ndlela kabuhlungu kwangethuba ngokuqhutywa kwee-POM bushings ekufuneka zidibene nezikhonkwane ezingenasici. Sibethelele ukunyamezelana, kodwa umxhasi wabuyela emva: i-bushings yayincwina. Ngoba? Besizifake ngoomatshini ngokucocekileyo kakhulu, umphezulu ubugudileyo kakhulu ukuba ungathanjiswanga. Ngamanye amaxesha, kwiiplastiki, ukugqitywa komphezulu ochanekileyo akuyiyo eyona igudileyo kwitshati.
Apha kulapho imvelaphi yokwenziwa kwezinto ngokubanzi iba xabiseke kakhulu. Thatha inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngaphezulu kweminyaka engama-30 yokuphosa kunye nokwenza iintsimbi-ingakumbi izinto ezikhohlisayo ezifana ne-nickel-based alloys-basondela kwizinto ezinentlonipho enzulu kwiipropati zendalo. Loo ngqondo iyaguqulela. Xa bephatha ngokuchanekileyo machining eplastiki, ayingomda; kukusetyenziswa kwaloo nzululwazi ingqongqo yezinto. Ukwazi indlela yokulawula igalelo lobushushu kunye noxinzelelo kwi-superalloy kukunika i-edge enembile yokulawula okufanayo kwiplastiki ephezulu yokusebenza njenge-PEEK, apho uxinzelelo olushiyekileyo lutshaba lozinzo lwe-dimensional.
Indlela yokupholisa yi-pitfall yakudala. Ukupholisa izikhukula? Ngokuqhelekileyo ngumbono ombi kwiiplastiki ezininzi zehygroscopic. Inokungena ngaphakathi kwaye ibangele ukudumba kamva. Umoya oxinanisiweyo ungcono, kodwa kufuneka ulawule ukufuduswa kwe-static kunye ne-chip. Kwezinye iijiyometri, sifumene ezona ziphumo zintle zivela kwisipholisi senkungu esilula, ekujoliswe kuso ngolwelo oluchanekileyo lwe-dielectric, into esiyilungisileyo emva kokuthetha nomenzi wokungunda. Kolu hlengahlengiso lwenkqubo encinci, engazange ikhankanywe kwincwadana yemigaqo, echaza ukuchaneka kokwenyani.
Izixhobo kunye nokuLungisa: UbuGcisa obuBuchule bokuBamba umva
Wonke umntu obsesses phezu isixhobo geometry-rake engile, helix for iiplastiki, etc. Oko kubalulekile, ngokuqinisekileyo. Kodwa ukulungiswa kulapho kuhlala khona imisebenzi okanye kufa. Ibambe nzima kakhulu kwiPC ebhityileyo okanye ityhubhu ye-acrylic? Uya kubona ushicilelo, okanye okubi ngakumbi, udale indawo yoxinzelelo eqhekeka kamva. I-vacuum chucks ilungile, kodwa kwiprototype okanye i-low-volume runs, ufumana ubuchule. Sisebenzise imihlathi ethambileyo eyenziwe ngoomatshini ukusuka kwi-urethane ye-durometer esezantsi, okanye nokusebenzisa ngobuchule itheyiphu enamacala amabini kwiindawo ezincinci, ezingenayo i-ferrous. Injongo kukuyibamba ngokwaneleyo ukuxhathisa amandla okusika, kodwa kungekhona ukuyigqwetha. Kukuziva uphuhlisa.
Ukunxitywa kwesixhobo kwenzeka ngokwahlukileyo, nako. Ngentsimbi, ubona umhlaba onxitywayo weflanki. Kwiiplastiki ezizaliswe yi-abrasive njengenayiloni ezaliswe yiglasi, isiphelo sokusika sinokufumana inkangeleko epholisiweyo, ephantse yabuthuntu ixesha elide ngaphambi kokuba itshiphuke, kwaye umphezulu wakho uwohloka ngokuzolileyo. Kufuneka ulandele oku ngenxalenye yomgangatho, hayi nje ngemitha yeyure. Sasungula ilogi elula kwizinto ezithile: Icandelo 50 i-surface Ra check. Ibambe ngaphezulu kwesixhobo esinye esithoba isidima phambi kokuba yonakalise ibhetshi.
Xa Ukuchaneka Kudibana nehlabathi lokwenyani
Ityala elihlala lihleli kum ibingumxhasi obedinga i-manifold encinci, entsonkothileyo ye-PVDF yesixhobo sokuhlalutya imichiza. Ushicilelo lubize ±0.025mm kwiibhore ezininzi ezidibanisayo. Sayitshintsha, sayilinganisa kwi-CMM, kwaye yayigqibelele. Sayithumela ngenqanawa. Yasilela kwindibano yabo. Ngoba? Babesebenzisa intsimbi engenastainless intambo yokufaka intambo, kwaye isenzo sokuyicinezela ivelise ubushushu obaneleyo bendawo kunye noxinzelelo ukuphazamisa ibhore ekufutshane ngeemicrons ezimbalwa-ngokwaneleyo ukwaphula ukunyamezela. Ukuchaneka kwethu kwakungenasiphako, kodwa asizange siphendule ngenyathelo elilandelayo kubomi becandelo.
Oko kusilela kwanyanzela utshintsho lwenkqubo. Kumacandelo alandelayo, songeze inyathelo lokuthomalalisa uxinzelelo emva komatshini, kwaye emva koko ukugqiba ukukhanya kokugqiba. Yongeza iindleko kunye nexesha, kodwa yahambisa inxalenye eyayihlala izinzile entsimini. Nantso umaleko efihliweyo ngokuchanekileyo machining eplastiki: ayisosimo senxalenye xa iphuma evenkileni, kodwa imeko yayo xa ifakwa emsebenzini. Lo mbono ubanzi yinto odla ngokuyibona kwiivenkile ezinelifa kumacandelo abalulekileyo. QSY, umzekelo, kunye nembali yayo kwi-investment casting kunye ne-machining yokufuna i-alloys, i-structural isetyenziselwa ukucinga malunga ne-post-processing, unyango lobushushu, kunye nokusebenza kokugqibela, kungekhona nje inyathelo lomatshini lokuzihlukanisa.
Ibhulorho esuka kwiMetal ukuya kwiPlastiki
Kukho ukungaqondi kakuhle ukuba ukwenziwa kweplastiki linyathelo lokuhla kwintsimbi. Ayiyo. Yingoma enxuseneyo nemingeni yayo yenqanaba lePhD. Ngapha koko, ubuchwephesha kwiintsimbi ezinzima kumatshini bunokuba yinzuzo enkulu. Uqeqesho lokulawula ukungcangcazela, ubushushu, kunye nokuphambuka kwesixhobo xa usenza i-Inconel yazisa ngokuthe ngqo indlela osondela ngayo kwicomposite ezaliswe yiglasi. Ingqondo yobunjineli benkqubo phezu komatshini olula ngundoqo.
Ndijonge izakhono zefemu efana QSY. I-shell mold casting, utyalo-mali, i-CNC machining ye-cobalt kunye ne-nickel alloys-ezi ziinkqubo ezifuna ulawulo olugqithisileyo. Ukusetyenziswa kwesakhelo solawulo sinye, olo qwalaselo lunye kwizatifikethi zezinto eziphathekayo kunye neeparamitha zenkqubo, kwiiplastiki yiyona nto iphakamisayo ukusuka kwinxalenye elula ukuya ethembekileyo. ngokuchanekileyo machining eplastiki. Kuthetha ukuqonda ukuba ubume bempahla (intonga, ipleyiti, icwecwe elibunjiweyo) linembali yalo yoxinzelelo, ukuba ubushushu bendawo yevenkile bubalulekile, nokuba ukupakishwa kwenqanawa kunokuchaphazela ukufuma.
Ekugqibeleni, Kumalunga nokulindela
Ngoko ke, yintoni enokuthatyathwa emva kweminyaka yoku? Ukuchaneka akulonani nje elikushicilelo. Yinkqubo. Iqala ngokumamela ngokwenene izinto eziphathekayo-ukwazi ukuba inayiloni iya kutsala amanzi, ukuba i-acetal ineqondo eliphantsi lokunyibilika, ukuba i-PTFE iya kukhwela phantsi komthwalo. Iyaqhubeka ngokuyila inkqubo ehlonipha ezo quirks, kunye neendlela zesixhobo ezinciphisa ubushushu, izilungiso ezingagqwethi, kunye nemilinganiselo ethathwe kwindawo ezinzileyo emva kokuba indawo iqhelekile.
Iyaphela, okona kubalulekileyo, ngokulindela ukuba kuya kwenzeka ntoni kwinxalenye emva kokuba ishiye ibhentshi yakho. Ngaba iya kuhlanganiswa? Ngaba iya kubona imijikelo yobushushu? Ngaba inxalenye yentsimbi iya kufakwa kuyo? Loo nto yokugqibela yokubona kwangaphambili yinto eyahlula umatshini onobuchule kwiqabane lokwenyani lemveliso. Ngumahluko phakathi kokwenza inxalenye echanekileyo kwi-vacuum kunye nokuhambisa icandelo eliqinisekisa ukuba umgca wokuhlanganisa umxhasi awuyeki, okanye imveliso yabo yokugqibela ayiphumeleli. Leyo yinjongo yokwenyani, kwaye ngokuphandle, eyona nto ibalulekileyo. Oomatshini zizixhobo nje zokufika apho; ulwazi lukwenza ichaneke.
