Lezi zifakwa zekama zenzelwe ukuthi zifakwe kubakaki abakhethekile futhi zisize ukuqeda imibimbi ezinhlobonhlobo zezinhlelo zokusebenza ze-crankshaft.
Iklayenti liza kuwe nomsebenzi wokwenza amapayipi angama-90-degree.Lolu hlelo lokusebenza ludinga 2″ amashubhu.Ububanzi Bangaphandle (OD), 0.065 in. Ukujiya kwezindonga, amayintshi angu-4.I-Centerline Radius (CLR).Ikhasimende lidinga izingcezu ezingu-200 ngeviki unyaka wonke.
Izidingo zokufa: ukugoba kuyafa, ukugoba kuyafa, ukucindezela kuyafa, ama-mandrels nokuhlanza kuyafa.ayikho inkinga.Kubukeka sengathi wonke amathuluzi adingekayo okugoba amanye ama-prototype asesitolo futhi alungele ukusebenza.Ngemva kokumisa uhlelo lomshini, opharetha ulayisha ipayipi futhi enze ukugoba kwesilingo ukuze aqinisekise ukuthi umshini udinga ukulungiswa.Kuqhamuke i-turn one yehle emotweni futhi iphelele.Ngakho-ke, umkhiqizi uthumela amasampula amaningana amapayipi agobile kumthengi, obese ephetha inkontileka, okuzoholela ebhizinisini elivamile elinenzuzo.Konke kubonakala kuhlelekile emhlabeni.
Kwadlula izinyanga, lona leli khasimende lafuna ukunciphisa izindleko zezinto ezibonakalayo.Lolu hlelo lokusebenza olusha ludinga 2″ OD x 0.035″ ubukhulu beshubhu.ukujiya kodonga namayintshi angu-3.I-CLR.Amathuluzi avela kolunye uhlelo lokusebenza aphethwe ngaphakathi yinkampani, ngakho-ke i-workshop ingakwazi ukukhiqiza ama-prototypes ngokushesha.Umsebenzisi ulayisha wonke amathuluzi kubhuleki lokucindezela futhi azame ukuhlola ukugoba.Ukugoba kokuqala kwavela kude nomshini onama-creases ngaphakathi kokugoba.Kungani?Lokhu kungenxa yengxenye yethuluzi elibaluleke kakhulu ukugoba amapayipi anezindonga ezincane kanye nama-radii amancane: i-wiper iyafa.
Enqubweni yokugoba ishubhu elisalungiswa elizungezayo, kwenzeka izinto ezimbili: udonga lwangaphandle lweshubhu luyawa futhi lube luncane, kuyilapho ingaphakathi leshubhu lishwabana futhi ligoqe.Izidingo ezincane zamathuluzi okugoba amapayipi anezingalo ezijikelezayo wukufa okugoba lapho ipayipi ligotshwa khona kanye ne-clamping die ukuze ibambe ipayipi endaweni lapho ligotshwa khona lapho ligoba khona.
I-clamping die isiza ukugcina ingcindezi eqhubekayo kwipayipi ku-tangent lapho ukugoba kwenzeka khona.Lokhu kunikeza amandla okusabela adala ukugoba.Ubude bokufa buncike ekugobeni kwengxenye kanye nerediyasi yomugqa omaphakathi.
Uhlelo lokusebenza ngokwalo luzonquma amathuluzi owadingayo.Kwezinye izimo, ukugoba kuphela kuyafa, ukugoqa kuyafa futhi ukucindezela kuyafa kuyadingeka.Uma umsebenzi wakho unezindonga eziwugqinsi ezikhiqiza i-radii enkulu, ungase ungadingi i-wiper die noma i-mandrel.Ezinye izinhlelo zokusebenza zidinga isethi ephelele yamathuluzi, okuhlanganisa ukufa kokugaya, i-mandrel, kanye (kweminye imishini) i-collet ukusiza ukuqondisa ipayipi nokugoba indiza yokuzungeza phakathi nenqubo yokugoba (bona Umfanekiso 1).
I-Squeegee dies isiza ukugcina nokuqeda imibimbi endaweni engaphakathi yokugoba.Baphinde banciphise ukuguga ngaphandle kwepayipi.Imibimbi kwenzeka lapho mandrel ngaphakathi ipayipi ingasakwazi ukunikeza amandla anele asebenzayo.
Lapho ugoba, i-wiper ihlale isetshenziswa nge-mandrel efakwe epayipini.Umsebenzi oyinhloko we-mandrel ukulawula ukuma kwe-radius yangaphandle yokugoba.I-Mandrels iphinde isekele i-radii yangaphakathi, nakuba inikeza kuphela ukusekelwa okugcwele kwezinhlelo zokusebenza ezibandakanya uhla olulinganiselwe lwama-D-bend kanye nezilinganiso zodonga.I-Bend D i-CLR yokugoba ehlukaniswe ububanzi obungaphandle bepayipi, futhi isici sodonga ububanzi obungaphandle bepayipi obuhlukaniswe ukushuba kodonga lwepayipi (bheka Umfanekiso 2).
I-Wiper efa isetshenziswa lapho i-mandrel ingasakwazi ukunikeza ukulawula okwanele noma ukusekelwa kwendawo engaba ngaphakathi.Njengomthetho ojwayelekile, ukufa kokuhlubula kuyadingeka ukugoba noma iyiphi i-mandrel enezindonga ezincane.(Ama-mandrel anezindonga ezincane ngezinye izikhathi abizwa ngokuthi ama-mandrels e-pitch amahle, futhi i-pitch ibanga phakathi kwamabhola ku-mandrel.) Ukukhetha kwe-Mandrel kanye nokufa kuncike ku-OD yepayipi, ukushuba kodonga lwamapayipi, kanye ne-radius yokugoba.
Izilungiselelo ezifanele zokufa kokugaya zibaluleka ikakhulukazi uma izinhlelo zokusebenza zidinga izindonga ezincanyana noma ama-radio amancane.Cabanga futhi ngesibonelo esisekuqaleni kwalesi sihloko.Yini esebenza ngamayintshi angu-4.I-CLR ingase ingalingani amayintshi angu-3.Izinguquko zezinto ezibonakalayo ezidingwa i-CLR namakhasimende ukonga imali zihambisana nokunemba okuphezulu okudingekayo ukuze kushune i-matrix.
Umfanekiso 1 Izingxenye eziyinhloko ze-rotary pipe bender ukubopha, ukugoba kanye nokubopha kuyafa.Okunye ukufakwa kungase kudinge ukuthi i-mandrel ifakwe ku-tube, kuyilapho ezinye zidinga ukusetshenziswa kwekhanda likadokotela mandrel.Ikholethi (engashiwongo lapha, kodwa izoba phakathi nendawo lapho uzofaka khona ishubhu) isiza ukuqondisa ishubhu ngesikhathi sokugoba.Ibanga phakathi kwe-tangent (iphuzu lapho ukugoba kwenzeka khona) kanye nethiphu ye-wiper ibizwa ngokuthi i-offset ye-wiper offset.
Ukukhetha ukufa kwe-scraper efanele, ukuhlinzeka ngokusekela okufanele kusukela ekugobeni kokufa, i-die kanye ne-mandrel, nokuthola indawo efanele yokufa kwe-wiper ukuze kuqedwe izikhala ezibangela ukushwabana nokungqubuzana yizihluthulelo zokukhiqiza izinga eliphezulu, ukugoba okuqinile.Ngokuvamile, indawo yethiphu yekama kufanele ibe phakathi kuka-0.060 no-0.300 amayintshi ukusuka ku-tangent (bona ukuchezuka kwekamu okungokomfanekiso okuboniswe kuMfanekiso 1), kuye ngosayizi weshubhu kanye nerediyasi.Sicela uhlole nomhlinzeki wakho wamathuluzi ukuze uthole ubukhulu obuqondile.
Qinisekisa ukuthi ichopho le-wiper die ligcwele i-tube groove nokuthi alikho igebe (noma "iqhubu") phakathi kwephuzu lokusula kanye ne-tube groove.Futhi hlola izilungiselelo zokucindezela kwesikhunta.Uma ikamu lisendaweni efanele ngokuphathelene ne-tube groove, cindezela kancane ku-matrix yokucindezela ukuze uphushe ishubhu ku-matrix egobile futhi usize ukushelela imibimbi.
Ama-wiper array afika ngezinhlobonhlobo zomumo nosayizi.Ungathenga amapayipi angama-rectangular/square wiper amapayipi angama-rectangular kanye nesikwele, futhi ungasebenzisa ama-contour/ama-wiper anomumo ukuze alingane umumo othize futhi usekele izici ezihlukile.
Izitayela ezimbili ezivame kakhulu i-matrix yesikwele-emuva yesikwele esisodwa kanye nesibambi sokusula esinezinsimbi.I-square back wiper iyafa (bona Umfanekiso 3) isetshenziselwa imikhiqizo emincane enezindonga, ukugoba kwe-D emincane (imvamisa engu-1.25D noma ngaphansi), i-aerospace, izinhlelo zokusebenza zobuhle eziphakeme, kanye nokukhiqizwa kwenqwaba encane kuya emaphakathi.
Kumajika angaphansi kuka-2D, ungaqala ngokufa kwesikwele esinesikwele, wenze inqubo ibe lula.Isibonelo, ungaqala nge-2D square back scraper curved scraper enesici sodonga esingu-150. Okunye, ungasebenzisa isibambi se-scraper esine-blade yezinhlelo zokusebenza ezinolaka oluncane njengamajika e-2D anesici sodonga esingu-25.
Amapuleti e-square back wiper ahlinzeka ngokusekela okuphezulu kwerediyasi yangaphakathi.Zingaphinde zisikwe ngemva kokugqoka ithiphu, kodwa kuzodingeka ulungise umshini ukuze uvumelane ne-wiper emfishane yokufa ngemva kokusika.
Olunye uhlobo oluvamile lwesibambi se-scraper blade lushibhile futhi lubiza kakhulu ekwenzeni ukugoba (bheka Umfanekiso 4).Angasetshenziselwa ukugoba okumaphakathi kuya kokuqinile kuka-D, kanye nokugoba amapayipi ahlukahlukene anobubanzi obufanayo bangaphandle kanye ne-CLR.Uma nje ubona ukuthi amathiphu, ungawashintsha.Uma wenza lokhu, uzobona ukuthi ithiphu isethwe ngokuzenzakalelayo endaweni efanayo neyeblade yangaphambilini, okusho ukuthi awudingi ukulungisa ukukhwezwa kwengalo ye-wiper.Nokho, qaphela ukuthi ukucushwa nendawo yokhiye we-blade kusibambi se-matrix esihlanzekile kuhlukile, ngakho-ke udinga ukwenza isiqiniseko sokuthi umklamo we-blade ufana nomklamo wokubamba ibhulashi.
Izibambi ze-Wiper ezinokufaka zinciphisa isikhathi sokusetha kodwa azinconywa kumaredi amancane.Futhi azisebenzi ngamashubhu angama-rectangular noma isikwele noma amaphrofayili.Kokubili amakamu e-wiper ayisikwele angemuva kanye nezingalo zokusula zingakhiqizwa eduze.Ama-wiper angaxhunywanga aklanyelwe ukunciphisa udoti wamapayipi, okuvumela ubude obufushane bokusebenza ngokunweba okunamathiselwe ngemuva kwesesula futhi kuvunyelwe ikholethi (ibhulokhi yomhlahlandlela weshubhu) ukuthi ibekwe eduze nendawo yokugoba (bheka uMdwebo 5).
Umgomo uwukufinyeza ubude bepayipi obudingekayo, ngaleyo ndlela ulondoloze izinto zokusetshenziswa okufanele.Nakuba lawa ma-wiper angathinteki enciphisa imfucuza, ahlinzeka ngokusekela okuncane kunama-wiper angemuva ayisikwele ajwayelekile noma ama-wiper mounts ajwayelekile anamabhulashi.
Qinisekisa ukuthi usebenzisa izinto ezingcono kakhulu zokufa ze-scraper.Ithusi le-aluminium kufanele lisetshenziswe lapho kugotshwa izinto eziqinile njengensimbi engagqwali, i-titanium kanye nama-alloys e-INCONEL.Uma ugoba izinto ezithambile ezifana nensimbi ethambile, ithusi ne-aluminium, sebenzisa insimbi noma i-chrome wiper yensimbi (bona umdwebo 6).
Umfanekiso 2 Ngokuvamile, izinhlelo zokusebenza ezinolaka kancane azidingi chip yokuhlanza.Ukuze ufunde leli shadi, bona okhiye abangenhla.
Uma usebenzisa isibambo sommese esine-blade, isibambo ngokuvamile senziwe ngensimbi, kodwa kwezinye izimo kokubili isibambo kanye nethiphu kungase kudingeke ukuthi kube yithusi le-aluminium.
Kungakhathaliseki ukuthi usebenzisa ikamu noma into yokubamba ibhulashi enama-blade, uzobe usebenzisa ukusethwa komshini okufanayo.Ngenkathi ubambe ishubhu endaweni eboshwe ngokugcwele, beka i-scraper phezu kokugoba nangemuva kweshubhu.Ithiphu ye-wiper izongena endaweni ngokushaya ngemuva kwe-wiper array nge-mallet yerabha.
Uma ungeke ukwazi ukusebenzisa le ndlela, sebenzisa iso lakho nerula (rula) ukuze ufake i-wiper matrix noma isibambi se-wiper blade.Qaphela futhi usebenzise umunwe wakho noma inhlamvu yeso ukuze uqiniseke ukuthi ithiphu iqondile.Qinisekisa ukuthi ithiphu ayiphambili kakhulu.Ufuna inguquko ebushelelezi njengoba ithubhu idlula ichopho le-matrix ye-wiper.Phinda inqubo njengoba kudingeka ukuze uzuze ukugoba okuhle kwekhwalithi.
I-engeli ye-rake i-engeli ye-squeegee ngokuhlobene ne-matrix.Ezinye izinhlelo zokusebenza ezichwepheshile ku-aerospace nakweminye imikhakha zisebenzisa ama-wiper aklanywe ngamaraki amancane noma angenawo.Kodwa ezinhlelweni eziningi, i-engeli yokutsheka ivamise ukusethwa phakathi kuka-1 no-2 degrees, njengoba kukhonjisiwe kufig.1 ukuze unikeze imvume eyanele yokunciphisa ukudonsa.Uzodinga ukucacisa umthambeka oqondile phakathi nokusetha nokujika kokuhlola, nakuba ngezinye izikhathi ungase ukusethe ekujikeni kokuqala.
Usebenzisa i-matrix ye-wiper ejwayelekile, setha ithiphu le-wiper emuva kancane ngemuva kwe-tangent.Lokhu kushiya isikhala ku-opharetha ukuthi ahambise ithiphu yokuhlanza phambili njengoba igqoka.Kodwa-ke, ungalokothi ukhweze ithiphu le-wiper matrix ngokuzenzakalelayo noma ngale kwalokho;lokhu kuzolimaza ithiphu le-matrix ehlanzekile.
Lapho ugoba izinto ezithambile, ungasebenzisa amaraki amaningi njengoba udinga.Kodwa-ke, uma ugoba izinto eziqinile njengensimbi engagqwali noma i-titanium, zama ukugcina i-scraping ifa endaweni encane kakhulu.Sebenzisa into eqinile ukwenza i-scraper iqonde ngangokunokwenzeka, lokhu kuzosiza ukuhlanza ama-crease kuma-curve kanye nokuqondile ngemva kwamajika.Ukusetha okunjalo kufanele futhi kufake i-mandrel eqinile.
Ukuze uthole ikhwalithi engcono kakhulu yokugoba, i-mandrel kanye ne-scraper die kufanele isetshenziselwe ukusekela ingaphakathi lokugoba nokulawula ukuphuma kokujikeleza.Uma isicelo sakho sidinga i-squeegee ne-mandrel, sebenzisa kokubili futhi ngeke uzisole.
Ukubuyela enkingeni yangaphambilini, zama ukuwina inkontileka elandelayo yezindonga ezincanyana kanye ne-CLR ecinene.Njengoba isikhunta sokusula sisendaweni, ishubhu laphuma emshinini lingenasici ngaphandle kokushwabana.Lokhu kumelela izinga elifunwa yimboni, kanti ikhwalithi yiyona okufanele imboni.
