Zofunikira za kufa: kupindika kufa, kupukuta kumafa, makina osindikizira, mandrels ndi kuyeretsa kufa.palibe vuto.Zikuwoneka ngati zida zonse zofunika zopindika zina mwazomwe zili m'sitolo ndipo zakonzeka kupita.Pambuyo pokhazikitsa pulogalamu yamakina, wogwiritsa ntchitoyo amanyamula chitoliro ndikupanga kuyeserera kuti atsimikizire kuti makinawo akuyenera kusinthidwa.Chokhota chimodzi chinatsika mgalimotomo ndipo inali yabwino.Chifukwa chake, wopanga amatumiza zitsanzo zingapo zamapaipi opindika kwa kasitomala, ndiyeno amamaliza mgwirizano, womwe umabweretsa bizinesi yopindulitsa nthawi zonse.Chilichonse chikuwoneka kuti chili mwadongosolo padziko lapansi.
Miyezi inadutsa, ndipo kasitomala yemweyo ankafuna kuchepetsa ndalama zakuthupi.Ntchito yatsopanoyi imafuna machubu a 2 ″ OD x 0.035 ″ awiri.makulidwe a khoma ndi mainchesi 3.CLR.Zida zochokera ku ntchito ina zimachitikira mkati mwa kampani, kotero msonkhanowu ukhoza kupanga ma prototypes nthawi yomweyo.Wogwira ntchitoyo amanyamula zida zonse pa brake yosindikizira ndikuyesa kuyang'ana kupindika.Kupindika koyamba kunachokera ku makina okhala ndi ma creases mkati mwa bend.Chifukwa chiyani?Izi ndichifukwa cha chigawo cha chida chomwe chili chofunikira kwambiri pakupinda mapaipi okhala ndi makoma opyapyala ndi ma radii ang'onoang'ono: wiper kufa.
Popindika chubu chozungulira chozungulira, zinthu ziwiri zimachitika: khoma lakunja la chubu limagwa ndikukhala lochepa thupi, pomwe mkati mwa chubu limachepa ndikugwa.Zomwe zimafunikira pazida zopindika za chitoliro chokhala ndi mikono yozungulira ndi chopindika chomwe chitoliro chimapindika ndikumangirira kuti chitolirocho chikhale m'malo mwake pomwe chimapindika popindika.
Kufa kwa clamping kumathandiza kuti chitoliro chikhale chokhazikika pa tangent pomwe kupindika kumachitika.Izi zimapereka mphamvu yochitira yomwe imapanga bend.Kutalika kwa kufa kumadalira kupindika kwa gawolo ndi utali wozungulira wa mzere wapakati.
Ntchito yokhayo imatsimikizira zida zomwe mukufuna.Nthawi zina, kumangopindika kumafa, kumenyedwa kumafa ndikusindikiza kufa kumafunika.Ngati ntchito yanu ili ndi makoma okhuthala omwe amapanga radii yayikulu, simungafune wiper die kapena mandrel.Ntchito zina zimafuna zida zonse, kuphatikizapo mphero, mandrel, ndi (pamakina ena) collet yothandizira kutsogolera chitoliro ndi kupindika ndege yozungulira panthawi yopindika (onani Chithunzi 1).
Squeegee kufa kumathandiza kusunga ndi kuthetsa makwinya pa utali wamkati wa bend.Amachepetsanso kupunduka kwa kunja kwa chitoliro.Makwinya zimachitika pamene mandrel mkati chitoliro sangathenso kupereka zokwanira zotakataka mphamvu.
Popinda, chopukutacho chimagwiritsidwa ntchito nthawi zonse ndi mandrel omwe amalowetsedwa mu chitoliro.Ntchito yayikulu ya mandrel ndikuwongolera mawonekedwe a utali wakunja wa bend.Mandrels amathandiziranso ma radii amkati, ngakhale amangopereka chithandizo chokwanira pamapulogalamu okhudzana ndi magawo ena a D-bend ndi ma ratios a khoma.Bend D ndi bend CLR yogawidwa ndi kunja kwa chitoliro, ndipo khoma la khoma ndi kunja kwa chitoliro chogawidwa ndi makulidwe a khoma la chitoliro (onani Chithunzi 2).
Wiper amafa ntchito pamene mandrel sangathenso kupereka ulamuliro wokwanira kapena thandizo kwa utali wozungulira mkati.Monga lamulo, chovula chovula chimafunika kupindika mandrel aliwonse owonda.(Thin-walled mandrels nthawi zina amatchedwa fine pitch mandrels, ndipo phula ndi mtunda pakati pa mipira pa mandrel.) Mandrel ndi kufa kusankha zimadalira chitoliro OD, chitoliro khoma makulidwe, ndi bend utali wozungulira.
Zosintha zoyenera zogaya zimakhala zofunika makamaka pamene mapulogalamu amafuna makoma ang'onoang'ono kapena ma radiyo ang'onoang'ono.Taganiziraninso chitsanzo chimene chili kumayambiriro kwa nkhaniyi.Zomwe zimagwira ntchito 4 mainchesi.CLR ikhoza kusakwanira mainchesi atatu.Zosintha zomwe zimafunidwa ndi CLR ndi makasitomala kuti asunge ndalama zimatsagana ndi kulondola kwapamwamba komwe kumafunikira kukonza masanjidwewo.
Chithunzi 1 Zigawo zazikulu za bender ya chitoliro chozungulira ndikumangirira, kupindika ndi kumenya kufa.Kuyika kwina kungafunike kuti mandrel alowetsedwe mu chubu, pamene ena amafuna kugwiritsa ntchito mutu wa dokotala wa mandrel.Khola (lomwe silinatchulidwe apa, koma lidzakhala pakati pomwe mudzalowetsa chubu) limathandiza kutsogolera chubu panthawi yopindika.Mtunda pakati pa tangent (pamene kupindika kumachitika) ndi nsonga ya chofufutira amatchedwa theoretical wiper offset.
Kusankha scraper yolondola kufa, kupereka chithandizo choyenera kuchokera ku kupindika kufa, kufa ndi mandrel, ndikupeza malo oyenerera a wiper kufa kuti athetse mipata yomwe imayambitsa makwinya ndi kumenyana ndi makiyi opangira khalidwe lapamwamba, zomangira zolimba.Nthawi zambiri, nsonga ya zisa iyenera kukhala pakati pa 0.060 ndi 0.300 mainchesi kuchokera ku tangent (onani kupotokola kwachisa komwe kukuwonetsedwa pa Chithunzi 1), kutengera kukula kwa chubu ndi utali wozungulira.Chonde funsani ndi wopereka zida zanu kuti muwone kukula kwake.
Onetsetsani kuti nsonga ya chopukuta ndi yonyowa ndi chubu ndipo palibe kusiyana (kapena "kuphulika") pakati pa nsonga yopukuta ndi chubu.Yang'ananinso zokonda zanu za nkhungu.Ngati zisa zili pamalo oyenera potsata poyambira, ikani kanikiziro kakang'ono ku matrix okakamiza kukankhira chubu munjira yopindika ndikuthandizira kusalaza makwinya.
Ma Wiper amabwera m'mawonekedwe ndi makulidwe osiyanasiyana.Mutha kugula ma wiper a rectangular/square wiper pamapaipi amakona anayi ndi masikweya, ndipo mutha kugwiritsanso ntchito zopukuta zozungulira / zowoneka bwino kuti zigwirizane ndi mawonekedwe enaake ndikuthandizira mawonekedwe apadera.
Mitundu iwiri yodziwika kwambiri ndi matrix a square-back wiper matrix ndi chofukizira chala.Square back wiper imafa (onani Chithunzi 3) imagwiritsidwa ntchito pazinthu zopyapyala zokhala ndi mipanda, zopindika zopapatiza za D (nthawi zambiri 1.25D kapena kuchepera), zakuthambo, zokongoletsa kwambiri, komanso kupanga batch yaying'ono mpaka yapakati.
Kwa ma curve ochepera 2D, mutha kuyamba ndi wiper-back-backed wiper kufa, kuwongolera njirayo.Mwachitsanzo, mukhoza kuyamba ndi 2D square back curved scraper ndi khoma factor 150. Kapenanso, mungagwiritse ntchito scraper chofukizira ndi tsamba kwa ntchito zochepa aukali monga 2D curves ndi khoma factor 25.
Ma mbale a square back wiper amapereka chithandizo chokwanira cha radius yamkati.Athanso kudulidwa pambuyo povala nsonga, koma muyenera kusintha makinawo kuti agwirizane ndi kufa kwa wiper kwakanthawi mukadula.
Mtundu wina wamba wa scraper blade holder ndi wotsika mtengo komanso wokwera mtengo popanga bend (onani Chithunzi 4).Atha kugwiritsidwa ntchito ngati mapindika olimba a D, komanso kupindika mapaipi osiyanasiyana okhala ndi mainchesi akunja ndi CLR.Mukangowona kuti nsonga zavala, mutha kuzisintha.Mukachita izi, mudzawona kuti nsongayo imayikidwa pamalo omwewo monga tsamba lapitalo, kutanthauza kuti simuyenera kusintha kuyika kwa mkono wa wiper.Zindikirani, komabe, kuti masinthidwe ndi malo a kiyi ya tsamba pa chotengera chotsuka chotsuka ndi chosiyana, kotero muyenera kuwonetsetsa kuti kapangidwe ka tsambalo kamagwirizana ndi kapangidwe ka chogwirizira burashi.
Ma Wiper okhala ndi zoyikapo amachepetsa nthawi yoyika koma osavomerezeka pa radiyo yaying'ono.Sagwiranso ntchito ndi machubu amakona anayi kapena masikweya kapena mbiri.Zisa zonse za ma square back wiper ndi manja oyikapo amatha kupangidwa moyandikana.Ma wiper osalumikizana nawo adapangidwa kuti achepetse zinyalala zapaipi, kulola kuti utali wogwirira ntchito ukhale wamfupi pokulitsa chomata kumbuyo kwa chopukuta ndikulola kuti collet (chubu chowongolera) ayimitsidwe pafupi ndi chopindika (onani Chithunzi 5).
Cholinga ndikufupikitsa kutalika kwa chitoliro chomwe chimafunikira, potero kupulumutsa zinthu zogwiritsira ntchito moyenera.Ngakhale ma wiper osagwirawa amachepetsa zinyalala, amapereka chithandizo chocheperako kuposa ma wiper am'mbuyo am'mbuyo kapena ma wiper wamba okhala ndi maburashi.
Onetsetsani kuti mukugwiritsa ntchito zida zabwino kwambiri za scraper die.Mkuwa wa aluminiyamu uyenera kugwiritsidwa ntchito popinda zinthu zolimba monga chitsulo chosapanga dzimbiri, titaniyamu ndi aloyi a INCONEL.Mukapinda zinthu zofewa monga chitsulo chochepa, mkuwa ndi aluminiyamu, gwiritsani ntchito chitsulo kapena chrome chopukutira zitsulo (onani mkuyu 6).
Chithunzi 2 Nthawi zambiri, ntchito zocheperako sizifuna chipangizo choyeretsera.Kuti muwerenge tchatichi, onani makiyi omwe ali pamwambapa.
Mukamagwiritsa ntchito chogwirira cha mpeni chokhala ndi tsamba, chogwiriracho chimakhala chopangidwa ndi chitsulo, koma nthawi zina chogwirira ndi nsonga zimafunika kukhala aluminiyamu yamkuwa.
Kaya mumagwiritsa ntchito chisa kapena chogwirizira chokhala ndi masamba, mudzakhala mukugwiritsa ntchito makina omwewo.Pamene mukugwira chubu momangirira bwino, ikani chopukutira pamwamba pa kupindika ndi kumbuyo kwa chubu.Nsonga yopukutira idzalowa m'malo mwa kumenya kumbuyo kwa gulu la wiper ndi mallet a rabara.
Ngati simungathe kugwiritsa ntchito njirayi, gwiritsani ntchito diso lanu ndi wolamulira (wolamulira) kuti muyike matrix opukuta kapena chofukizira.Samalani ndikugwiritsa ntchito chala chanu kapena diso kuti muwonetsetse kuti nsongayo ndi yowongoka.Onetsetsani kuti nsongayo siili patsogolo kwambiri.Mukufuna kusintha kosalala pamene chubu chikudutsa nsonga ya masanjidwewo a wiper.Bwerezani ndondomekoyi ngati mukufunikira kuti mukhale ndi bend yabwino.
Mlingo wa rake ndi ngodya ya squeegee mogwirizana ndi matrix.Ntchito zina zamaluso muzamlengalenga ndi zina zimagwiritsa ntchito ma wiper opangidwa opanda ma rakes ochepa.Koma pazinthu zambiri, mbali yopendekeka nthawi zambiri imayikidwa pakati pa 1 ndi 2 madigiri, monga momwe zikusonyezedwera mkuyu.1 kuti mupereke chilolezo chokwanira kuti muchepetse kukokera.Mudzafunika kudziwa kotsetsereka kwenikweni pokhazikitsa ndi kutembenuka koyesa, ngakhale nthawi zina mutha kuyiyika poyambira koyamba.
Pogwiritsa ntchito matrix wamba wa wiper, ikani chopukuta pang'ono kumbuyo kwa tangent.Izi zimasiya mpata kuti wogwiritsa ntchito asunthire nsonga yotsukira kutsogolo pamene imavala.Komabe, musamakweze nsonga ya matrix a wiper tangentially kapena kupitirira;izi zidzawononga nsonga ya matrix oyeretsa.
Mukapinda zida zofewa, mutha kugwiritsa ntchito ma rakes ambiri momwe mungafunire.Komabe, ngati mukupinda zida zolimba monga chitsulo chosapanga dzimbiri kapena titaniyamu, yesetsani kuti scraping isafe pang'ono potsetsereka.Gwiritsani ntchito zinthu zolimba kuti scraper ikhale yowongoka momwe mungathere, izi zidzathandiza kuyeretsa ma creases m'mipingo ndi zowongoka pambuyo pa ma curve.Kukonzekera kotereku kuyeneranso kukhala ndi mandrel olimba.
Kuti mukhale wabwino kwambiri wopindika, mandrel ndi scraper die ayenera kugwiritsidwa ntchito kuthandizira mkati mwa bend ndikuwongolera kunja-kuzungulira.Ngati ntchito yanu ikufuna squeegee ndi mandrel, gwiritsani ntchito zonsezi ndipo simudzanong'oneza bondo.
Kubwerera ku vuto lakale, yesetsani kupambana mgwirizano wotsatira wa makoma owonda komanso olimba a CLR.Ndi chopukutira nkhungu m'malo, chubucho chinatuluka pamakina mosalakwitsa popanda makwinya.Izi zikuyimira mtundu womwe makampani akufuna, ndipo mtundu ndi womwe makampaniwo akuyenera.
