Anthu ambiri akamva 'makina apulasitiki olondola' amawona makina a CNC akung'ung'udza, mwina chipinda choyera, ndi zida zowoneka bwino. Ndicho chithunzi cha malonda. Chowonadi, chomwe mumaphunzira mutataya PEEK ya madola mazana angapo kapena kuyang'ana gawo la UHMWPE lololerana kwambiri patatha sabata pambuyo pobereka, ndikuti kulondola apa kuli zambiri zokhudzana ndi psychology monga momwe zimakhalira kuwongolera makina. Ndi kukambirana pakati pa kulimba kwa chiphunzitso chodula zitsulo ndi kusinthasintha, nthawi zambiri kupsa mtima, chikhalidwe cha ma polima. Mashopu ambiri omwe ali ndi zitsulo zonyezimira amapunthwa pano, amachitira pulasitiki ngati aluminiyamu yofewa, ndipo ndipamene mavuto-ndi kuphunzira kwenikweni kumayambira.
Nkhaniyi Ndi Yoyamba Yosinthika, Osati Yokhazikika
Simungathe kungoyika pulogalamu yapulasitiki yokhazikika. Banja lililonse la polima limakhala ngati mitundu yosiyana. Machining delrin (POM) ndi loto-ndilokhazikika, lodziwikiratu, tchipisi bwino. Mumaona kuti ndinu otetezeka. Ndiye inu kusintha kwa nayiloni kapena PTFE, ndipo mwadzidzidzi mukulimbana ndi mayamwidwe a chinyezi ndi kufalikira kwapakati pakatikati. Gawo lomwe mudaliyeza bwino pa benchi yamakina lachoka pa ola limodzi pambuyo pake. Ndidaphunzira izi movutikira koyambirira ndikuthamanga kwa ma POM tchire omwe amayenera kukhala ndi mapini osapanga. Tidakhomerera kulolerana, koma kasitomala adayimbanso: ma bushings anali kukuwa. Chifukwa chiyani? Tinkawapanga mwaukhondo kwambiri, pamwamba pake kunali kosalala kwambiri kuti tisakonzeke mafuta. Nthawi zina, kwa mapulasitiki, kumalizidwa koyenera pamwamba sikumakhala kosalala kwambiri pa tchati.
Apa ndipamene maziko akukonza zinthu zambiri amakhala ofunika kwambiri. Tengani kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd.. Pazaka zopitilira 30 akuponya ndi kupanga zitsulo -makamaka zinthu zachinyengo monga ma aloyi opangidwa ndi faifi tambala - amayandikira zida molemekeza kwambiri zinthu zomwe adabadwa nazo. Maganizo amenewo amamasulira. Pamene akugwira mwatsatanetsatane makina apulasitiki, si m'mbali; ndikugwiritsa ntchito sayansi yokhwima yomweyi. Kudziwa momwe mungasamalire kutentha ndi kupsinjika mu superalloy kumakupatsani mwayi wowongolera zomwezo mu pulasitiki yochita bwino kwambiri ngati PEEK, pomwe kupsinjika kotsalira ndi mdani wa kukhazikika kwa dimensional.
Njira yoziziritsira ndi dzenje lachikale. Zoziziritsira kusefukira? Nthawi zambiri lingaliro loyipa la mapulasitiki ambiri a hygroscopic. Imatha kulowa mkati ndikuyambitsa kutupa pambuyo pake. Mpweya woponderezedwa ndi wabwinoko, koma muyenera kuyang'anira kusamuka kwa static ndi chip. Kwa ma geometries ena, tidapeza zotulukapo zabwino kwambiri zochokera kumadzi ozizira, omwe amawunikiridwa ndi ma dielectric fluid, zomwe tidasintha titalankhula ndi wopanga nkhungu. Ndi kusintha kwakung'ono kumeneku, komwe sikunatchulidwe mu buku la makina, komwe kumatanthauzira kulondola kwenikweni.
Zida ndi Kukonza: Luso Lobisika Logwira Mmbuyo
Aliyense amayang'ana kwambiri zida za geometry-rake angles, helix ya mapulasitiki, ndi zina zotero. Ndizofunikira, zedi. Koma kukonza ndi komwe ntchito zimakhala kapena kufa. Gwirani mwamphamvu kwambiri pa PC yokhala ndi mipanda yopyapyala kapena chubu la acrylic? Mudzawona chizindikirocho, kapena choyipitsitsa, chimapanga malo opanikizika omwe amasweka pambuyo pake. Vacuum chucks ndiabwino, koma kwa ma prototype kapena otsika kwambiri, mumapanga kupanga. Tagwiritsa ntchito nsagwada zofewa zomwe zidapangidwa kuchokera ku urethane yapansi-durometer, kapena kugwiritsa ntchito mwanzeru tepi ya mbali ziwiri pazigawo zing'onozing'ono, zopanda chitsulo. Cholinga chake ndikuchigwira mokwanira kukana mphamvu zodulira, koma osati kusokoneza. Ndikumverera komwe mumakulitsa.
Kuvala zida kumachitikanso mosiyana. Muzitsulo, mumawona malo ovala m'mbali. M'mapulasitiki odzaza ndi abrasive ngati nayiloni yodzazidwa ndi magalasi, m'mphepete mwake mumatha kukhala opukutidwa, owoneka ngati osasunthika nthawi yayitali asanagwe, ndipo kumapeto kwanu kumatsika mwakachetechete. Muyenera kutsatira izi ndi gawo la mtundu, osati ndi mita ya ola lokha. Tidayambitsa chipika chosavuta cha zida zina: Gawo 50 cheke cha Ra. Idagwira zida zopitilira chimodzi isanawononge gulu.
Pamene Precision Ikumana ndi Dziko Lenileni
Mlandu womwe umakhalabe ndi ine unali kasitomala yemwe amafunikira kachipangizo kakang'ono, kocholowana ka PVDF kachipangizo kosanthula mankhwala. Zosindikizazo zimafuna ± 0.025mm pamabowo angapo olumikizana. Tinazipanga, kuziyeza pa CMM, ndipo zinali zangwiro. Tinatumiza. Izo zinalephera mu msonkhano wawo. Chifukwa chiyani? Anali kugwiritsa ntchito chitsulo chosapanga dzimbiri choyikapo, ndipo mchitidwe wokanikiziramo udatulutsa kutentha kokwanira komweko ndi kupsinjika komwe kumapangitsa kuti chibowocho chiwonongeke ndi ma microns angapo - zokwanira kuti zithetse kulolerana. Makina athu olondola anali opanda cholakwika, koma sitinawerengere gawo lotsatira la moyo wa gawolo.
Kulephera kumeneko kunakakamiza kusintha kwa ndondomeko. M'magawo otsatirawa, tidawonjeza sitepe yochepetsera kupsinjika pambuyo pakukonza, kenako ndikumaliza komaliza. Idawonjezera mtengo ndi nthawi, koma idapereka gawo lomwe lidakhazikika m'munda. Ndiwo gawo lobisika la mwatsatanetsatane makina apulasitiki: sikungokhala momwe gawolo likuchoka m'sitolo, koma ndi momwe zimagwirira ntchito. Mawonedwe athunthu awa ndichinthu chomwe mumawona nthawi zambiri m'masitolo omwe ali ndi cholowa m'magawo ofunikira. Mtengo wa QSY, mwachitsanzo, ndi mbiri yake pakupanga ndalama komanso kukonza ma alloys ofunikira, amagwiritsidwa ntchito poganiza za kukonzanso, kutentha, ndi ntchito yomaliza, osati kungopanga gawo lodzipatula.
The Bridge from Metal to Plastic
Pali lingaliro lolakwika kuti makina apulasitiki ndi sitepe yotsika kuchokera kuzitsulo. Si. Ndi njira yofananira yomwe ili ndi zovuta zake zamtundu wa PhD. M'malo mwake, ukatswiri pazitsulo zovuta ku makina ungakhale mwayi waukulu. Lamulo la kuwongolera kugwedezeka, kutentha, ndi kupotoza kwa zida pamene mphero Inconel imadziwitsa mwachindunji momwe mumafikira gulu lodzaza magalasi. Lingaliro la uinjiniya wamakina pa makina osavuta ndikofunikira.
Ndikuwona luso la kampani ngati Mtengo wa QSY. Kuponyera nkhungu za zipolopolo, kupanga ndalama, kukonza makina a CNC a cobalt ndi nickel alloys - izi ndi njira zomwe zimafuna kuwongolera kwambiri. Kugwiritsa ntchito dongosolo lomwelo lowongolera, kuyang'ana komweku kwa ziphaso zakuthupi ndi magawo azinthu, kumapulasitiki ndizomwe zimakweza kuchoka pakupanga magawo kukhala odalirika. mwatsatanetsatane makina apulasitiki. Zimatanthawuza kumvetsetsa kuti mawonekedwe a katundu (ndodo, mbale, zopanda kanthu) zili ndi mbiri yakeyake yopanikizika, kuti kutentha kwa sitolo kumakhudza, komanso kuti zonyamula katundu zingakhudze chinyezi.
Pamapeto pake, Ndi Za Kuyembekezera
Ndiye, chotengera chiyani pambuyo pa zaka izi? Kulondola si nambala chabe pa kusindikiza. Ndi dongosolo. Zimayamba ndi kumvetsera moona mtima zakuthupi-podziwa kuti nayiloni idzayamwa madzi, kuti acetal imakhala ndi malo otsika osungunuka, kuti PTFE idzayenda pansi pa katundu. Ikupitiliza kupanga njira yomwe imalemekeza zovutazo, ndi zida zomwe zimachepetsa kutentha, zosintha zomwe sizisokoneza, ndi miyeso yomwe imatengedwa pamalo okhazikika gawolo litakhazikika.
Zimatha, chofunika kwambiri, ndikuyembekezera zomwe zidzachitike ku gawolo litasiyidwa pa benchi yanu. Kodi idzasonkhanitsidwa? Kodi idzawona mayendedwe a kutentha? Kodi chigawo chachitsulo chidzaikidwa mmenemo? Kuwoneratu komalizako ndi komwe kumalekanitsa katswiri wamakina waluso ndi mnzake weniweni wopanga. Ndiko kusiyana pakati pa kupanga gawo lomwe liri lolondola mu vacuum ndi kupereka chigawo chomwe chimatsimikizira kuti mzere wa msonkhano wa kasitomala usayime, kapena mapeto awo salephera. Ndicho cholinga chenicheni, ndipo kunena zoona, chinthu chokhacho chofunika. Makinawa ndi zida chabe zofikira kumeneko; chidziwitso ndi chomwe chimapangitsa kulondola.
