Iyo abantu benshi bumvise 'gutunganya neza plastike', bashushanya imashini ya CNC yikubita hasi, ahari icyumba gisukuye, nibice bisa neza. Iyo niyo shusho yo kwamamaza. Ukuri, uwo wiga nyuma yo gukuraho amadorari magana make ya PEEK cyangwa ukareba igice cyihanganira igice cya UHMWPE icyumweru nyuma yo kubyara, ni uko ibisobanuro hano byerekeranye na psychologiya yibintu nkuko bijyanye na kalibrasi yimashini. Numushyikirano hagati yubukomezi bwa dogma ikata ibyuma na flexible, akenshi imiterere, imiterere ya polymers. Amaduka menshi afite ibyuma byatsitaye hano, afata plastike nka aluminiyumu yoroshye, kandi niho ibibazo bitangirira - no kwiga nyabyo.
Ibikoresho ni Byambere Ibihinduka, Ntabwo bihoraho
Ntushobora gupakira gusa porogaramu rusange. Buri muryango wa polymer witwara nkubwoko butandukanye. Imashini delrin (POM) ninzozi - irahamye, iteganijwe, chip neza. Urumva nabi umutekano. Noneho uhindukire nylon cyangwa PTFE, hanyuma mu buryo butunguranye urwanya kwinjiza amazi no kwagura ubushyuhe hagati. Igice wapimye neza ku ntebe ya mashini ntikiboneka nyuma yisaha imwe. Ibi nabyize inzira igoye hakiri kare hamwe no kwiruka kwa POM yagombaga guhura na pin idafite ingese. Twashyizeho imisumari yo kwihanganira, ariko umukiriya yahamagaye inyuma: ibihuru byatontomaga. Kubera iki? Twabikoresheje neza cyane, hejuru yari yoroshye cyane kubwamavuta yagenewe. Rimwe na rimwe, kuri plastiki, hejuru yuburyo bwuzuye ntabwo aribwo bworoshye cyane ku mbonerahamwe.
Aha niho hambere mugutunganya ibintu byagutse biba ingirakamaro. Fata isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Hamwe nimyaka irenga 30 mugukora no gutunganya ibyuma-cyane cyane ibintu byoroshye nkibikomoka kuri nikel-begera ibikoresho-bubaha ibikoresho byubaha cyane imitungo yabyo. Iyo mitekerereze irasobanura. Iyo bitwaye gutunganya neza plastike, ntabwo ari kuruhande; ni ugukoresha ubwo bumenyi bukomeye. Kumenya gucunga ubushyuhe no guhangayika muri superalloy biguha urwego rwimbitse rwo gucunga kimwe muri plastiki ikora cyane nka PEEK, aho guhangayika bisigaye ari umwanzi wumutekano uhagaze.
Uburyo bwo gukonjesha ni umutego wa kera. Umwuzure ukonje? Akenshi igitekerezo giteye ubwoba kuri plastiki nyinshi ya hygroscopique. Irashobora gucengera igatera kubyimba nyuma. Umwuka ucanye ni mwiza, ariko ugomba gucunga static na chip evacuation. Kuri geometrike zimwe, twasanze ibisubizo byiza byaturutse kubintu byoroheje, bigamije gukonjesha hamwe na fluide ya dielectric iburyo, ikintu twahinduye nyuma yo kuvugana nuwabikoze. Nibikorwa bito byo guhuza n'imihindagurikire y'ikirere, bitigeze bivugwa mu gitabo cy'imashini, bisobanura neza ukuri.
Igikoresho no Gutunganya: Ubuhanzi Bworoheje bwo Gufata Inyuma
Umuntu wese yitaye kubikoresho bya geometrie - inguni ya rake, helix ya plastiki, nibindi birakomeye, byanze bikunze. Ariko guhuza niho imirimo iba cyangwa ipfa. Fata cyane kuri PC cyangwa uruzitiro ruto? Uzabona ibyanditse, cyangwa bibi, kora ingingo ihangayikishije nyuma. Vacuum chucks ninziza, ariko kuri prototype cyangwa amajwi make yiruka, ubona guhanga. Twifashishije ibicuruzwa byoroheje-jaws byakozwe kuva urethane yo hepfo-durometero, cyangwa no gukoresha ingamba zo gukoresha kaseti y'impande ebyiri kubice bito, bidafite ferrous. Intego nukuyifata bihagije kugirango irwanye imbaraga zo guca, ariko ntizigoreka. Nibyiyumvo utera imbere.
Kwambara ibikoresho bibaho ukundi, kandi. Mu byuma, urabona impande zambara. Muri plastiki zuzuye zuzuye nka nylon yuzuye ibirahuri, gukata birashobora kubona isura nziza, hafi yijimye mbere yuko ikata, kandi ubuso bwawe burangirika bucece. Ugomba gukurikirana ibi ukurikije ubuziranenge, ntabwo ukoresheje metero yisaha gusa. Twashyizeho ibiti byoroshye kubikoresho bimwe: Igice cya 50 hejuru Ra kugenzura. Yafashe ibikoresho birenze kimwe bitesha agaciro mbere yo kwangiza icyiciro.
Iyo Precision ihuye nisi nyayo
Urubanza rukomezanya nanjye ni umukiriya wari ukeneye ibintu bito, bigoye bivuye muri PVDF kubikoresho byo gusesengura imiti. Ibicapo byahamagaye ± 0.025mm kuri bores nyinshi zihuza. Twarayikoze, tuyipima kuri CMM, kandi yari itunganye. Twarayohereje. Ntabwo byananiye mu iteraniro ryabo. Kubera iki? Bakoreshaga icyuma kidafite ingese, kandi igikorwa cyo kugikanda cyabyaye ubushyuhe buhagije bwaho kandi bigahangayikishwa no kugoreka bore yegeranye na microne nkeya - bihagije kugirango bihangane. Gutunganya neza kwacu kwari kutagira inenge, ariko ntitwabaze intambwe ikurikira mubuzima bwigice.
Ibyo kunanirwa byatumye inzira ihinduka. Kubice byakurikiyeho, twongeyeho stress-yoroheje annealing intambwe nyuma yo gutunganya, hanyuma urumuri rwanyuma rurangiza. Yongeyeho ikiguzi nigihe, ariko yatanze igice cyagumye gihamye mumurima. Nibyo byihishe bya gutunganya neza plastike: ntabwo imiterere y igice gusa iyo ivuye mu iduka, ahubwo leta yayo iyo ishyizwe kukazi. Iyi mitekerereze yuzuye nikintu ukunze kubona mumaduka afite umurage mubice bikomeye. QSY, nkurugero, hamwe namateka yarwo mugushora imari no gutunganya ibicuruzwa bisabwa, ikoreshwa muburyo bwo gutekereza kubyakozwe nyuma yo gutunganywa, kuvura ubushyuhe, nibikorwa byanyuma, ntabwo ari intambwe yo gukora wenyine.
Ikiraro kuva mu cyuma kugera kuri plastiki
Hariho kwibeshya ko gutunganya plastike ari intambwe iva mubyuma. Ntabwo aribyo. Ninzira ibangikanye nibibazo byayo bya PhD. Mubyukuri, ubuhanga mubyuma bigoye kumashini birashobora kuba inyungu nini. Indero yo kugenzura kunyeganyega, ubushyuhe, no gutandukanya ibikoresho mugihe usya Inconel iramenyesha mu buryo butaziguye uburyo wegera ikirahuri cyuzuye ikirahure. Imitekerereze yubuhanga butunganya imashini yoroshye ni urufunguzo.
Ndebye ubushobozi bwikigo nka QSY. Gukora ibishishwa, gushora imari, gutunganya CNC ya cobalt na nikel alloys - izi ni inzira zisaba kugenzura bikabije. Gushyira mu bikorwa ubwo buryo bumwe bwo kugenzura, iryo genzura rimwe ku byemezo bifatika n'ibipimo bitunganyirizwa, kuri plastiki nibyo bizamura kuva mubice byoroheje bikora kugeza byizewe gutunganya neza plastike. Bisobanura kumva ko imiterere yimigabane (inkoni, isahani, ibumba ryubatswe) ifite amateka yacyo yibibazo, ko ubushyuhe bwibidukikije bwibidukikije bifite akamaro, kandi ko gupakira ibicuruzwa bishobora kugira ingaruka kubirimo.
Mukurangiza, Byerekeranye no Gutegereza
None, ni ubuhe buryo bwo gufata nyuma yimyaka yibi? Icyitonderwa ntabwo ari umubare gusa ku icapiro. Ni sisitemu. Bitangirana no kumva rwose ibikoresho - uzi ko nylon izakurura amazi, ko acetal ifite aho ishonga, PTFE izanyerera munsi yumutwaro. Irakomeza hamwe no gutegura inzira yubaha ibyo bisambo, hamwe ninzira nyabagendwa igabanya ubushyuhe, ibikoresho bitagoreka, hamwe n'ibipimo byafashwe ahantu hatuje nyuma yuko igice kimaze kuba gisanzwe.
Irangira, cyane cyane, hamwe no gutegereza ibizaba igice nyuma yo kuva ku ntebe yawe. Bizaterana? Bizabona ubushyuhe bwikurikiranya? Ese icyuma kizashyirwamo? Ako kantu ka nyuma ko gushishoza nicyo gitandukanya umukanishi ubishoboye nabafatanyabikorwa nyabo bakora. Ni itandukaniro riri hagati yo gukora igice gisobanutse neza mu cyuho no gutanga igice cyemeza ko umurongo witeranirizo wabakiriya udahagarara, cyangwa ibicuruzwa byabo byanyuma ntibinanirwa. Iyo niyo ntego nyayo, kandi mvugishije ukuri, ikintu cyonyine cyingenzi. Imashini nibikoresho gusa kugirango tugereyo; ubumenyi nicyo kibisobanura neza.
