Ezi zifakelo zekama ziyilelwe ukuba zifakwe kwizibiyeli ezikhethekileyo kwaye zincede ukuphelisa imibimbi kwiinkqubo ezahlukeneyo ze-crankshaft.
Umxhasi uza kuwe nomsebenzi wokwenza umbhobho we-90-degree.Olu setyenziso lufuna 2″ iityhubhu.I-Outer Diameter (OD), 0.065 in. Ubukhulu bodonga, i-intshi ezi-4.Umbindi weRadiyo (CLR).Umthengi ufuna amaqhekeza angama-200 ngeveki ngonyaka.
Iimfuno zokufa: ukugoba kuyafa, ukugoba kuyafa, i-press iyafa, i-mandrels kunye nokucoca kuyafa.akhongxaki.Kubonakala ngathi zonke izixhobo eziyimfuneko zokugoba ezinye zeeprototypes zisevenkileni kwaye zilungele ukuhamba.Emva kokumisela inkqubo yomatshini, umqhubi ulayisha umbhobho kwaye enze ukugoba kwesilingo ukuqinisekisa ukuba umatshini kufuneka ulungiswe.Ujike omnye wehla emotweni kwaye ilungile.Ngaloo ndlela, umenzi uthumela iisampulu ezininzi zeepayipi ezigobileyo kumthengi, othi ke agqibe isivumelwano, esiya kukhokelela kwishishini eliqhelekileyo elinenzuzo.Yonke into ibonakala ime ngocwangco ehlabathini.
Kwaqengqeleka iinyanga, yaye kwaloo mthengi wayefuna ukunciphisa iindleko zezinto eziphathekayo.Olu setyenziso lutsha lufuna 2″ OD x 0.035″ ishubhu edayamitha.ubukhulu bodonga kunye ne-intshi ezi-3.I-CLR.Izixhobo ezisuka kwesinye isicelo zibanjwe ngaphakathi yinkampani, ngoko iworkshop inokuvelisa ngokukhawuleza iiprototypes.Umsebenzisi ulayisha zonke izixhobo kwi-brake yokushicilela kwaye uzama ukujonga ukugoba.Ukugoba kokuqala kwavela kumatshini onamaqhekeza ngaphakathi kwi-bend.Ngoba?Oku kungenxa yecandelo lesixhobo esibaluleke kakhulu ukugoba imibhobho eneendonga ezincinci kunye ne-radii encinci: i-wiper iyafa.
Kwinkqubo yokugoba ityhubhu eyidrafti ejikelezayo, kwenzeka izinto ezimbini: udonga lwangaphandle lombhobho luyawa kwaye lube luncinci, ngelixa ingaphakathi lombhobho liyancipha kwaye liwa.Ubuncinci beemfuno zezixhobo zokugoba zemibhobho ezineengalo ezijikelezayo kukugoba ukugoba apho umbhobho ugobile kwaye i-clamping die ukubamba umbhobho kwindawo njengoko ugobile ujikeleze ukufa.
I-clamping die inceda ukugcina uxinzelelo oluqhubekayo kumbhobho kwi-tangent apho i-bend iyenzeka khona.Oku kunika amandla okusabela okwenza ukugoba.Ubude bokufa buxhomekeke kwi-curvature yecandelo kunye ne-radius yomgca ophakathi.
Isicelo ngokwaso siya kugqiba izixhobo ozidingayo.Kwezinye iimeko, ukugoba kuphela kuyafa, ukugoba kuyafa kwaye ucinezelo uyafa.Ukuba umsebenzi wakho iindonga ezishinyeneyo ezivelisa radii enkulu, usenokungafuni wiper die okanye mandrel.Ezinye izicelo zifuna iseti epheleleyo yezixhobo, kubandakanywa ukufa kokusila, i-mandrel, kunye (kwezinye iimatshini) i-collet yokunceda ukukhokela umbhobho kunye nokugoba indiza yokujikeleza ngexesha lokugoba (jonga uMfanekiso 1).
I-squeegee ifa inceda ukugcina kunye nokuphelisa imibimbi kwiradius yangaphakathi yokugoba.Bakwacutha ukonakala okungaphandle kwemibhobho.Imibimbi kwenzeka xa mandrel ngaphakathi umbhobho akasakwazi ukunika amandla asebenzayo ngokwaneleyo.
Xa ukugoba, i-wiper isoloko isetyenziswa kunye ne-mandrel efakwe kumbhobho.Umsebenzi ophambili we-mandrel kukulawula imilo yeradiyasi yangaphandle yokugoba.I-Mandrels nayo ixhasa i-radii yangaphakathi, nangona ibonelela kuphela ngenkxaso epheleleyo kwizicelo ezibandakanya uluhlu oluthile lwe-D-bends kunye nemilinganiselo yodonga.I-Bend D yi-CLR ye-bend eyahlulwe ngaphandle kobubanzi bombhobho, kwaye i-factor yodonga yi-diameter yangaphandle yombhobho eyahlulwe ngobunzima bodonga lombhobho (jonga uMzobo 2).
Wiper uyafa zisetyenziswa xa mandrel akasakwazi ukunika ulawulo olwaneleyo okanye inkxaso radius ngaphakathi.Njengomgaqo jikelele, a ukuhluba die kufuneka ukugoba nayiphi mandrel obhityileyo-eludonga.(Thin-walled mandrels mandrels mandrel mandrel mandrel mandrel mandrel, kwaye pitch umgama phakathi kweebhola kwi mandrel.) Mandrel kunye fa ukhetho kuxhomekeke OD umbhobho, umbhobho udonga ubukhulu, kunye nerediyasi bend.
Iisetingi ezifanelekileyo zokusila zibaluleke kakhulu xa izicelo zifuna iindonga ezibhityileyo okanye iradiya encinci.Khawucinge kwakhona ngomzekelo osekuqaleni kweli nqaku.Yintoni esebenza kwi-intshi ezi-4.I-CLR isenokungangeni ii-intshi ezi-3.Utshintsho lwezinto ezifunekayo yi-CLR kunye nabathengi ukugcina imali ihamba kunye nokuchaneka okuphezulu okufunekayo ukutshiza i-matrix.
Umzobo 1 Amacandelo aphambili e-rotary pipe bender i-clamping, ukugoba kunye nokudibanisa kuyafa.Ezinye ufakelo kungafuna mandrel ukuba ifakwe ityhubhu, lo gama abanye kufuna ukusetyenziswa intloko mandrel ugqirha.I-collet (engaqanjwanga apha, kodwa iya kuba sembindini apho uya kufaka ityhubhu) inceda ukukhokela ityhubhu ngexesha lokugoba.Umgama phakathi kwe-tangent (indawo apho ukugoba kwenzeka khona) kunye nencam ye-wiper ibizwa ngokuba yi-theoretical wiper offset.
Ukukhetha i-scraper echanekileyo yokufa, ukubonelela ngenkxaso efanelekileyo kwi-egoba die, die and mandrel, kunye nokufumana indawo echanekileyo yokufa kwe-wiper ukuphelisa izithuba ezibangela ukushwabana kunye ne-warping zizitshixo zokuvelisa umgangatho ophezulu, ukugoba okuqinileyo.Ngokuqhelekileyo, indawo yencopho yekama kufuneka ibe phakathi kwe-0.060 kunye ne-0.300 intshi ukusuka kwi-tangent (bona i-theory comb deflection eboniswe kuMzobo 1), kuxhomekeke kubukhulu betyhubhu kunye neradius.Nceda uqhagamshelane nomthengisi wakho wesixhobo malunga nemilinganiselo echanekileyo.
Qinisekisa ukuba incam ye-wiper die igungxulwe kunye ne-tube groove kwaye akukho sithuba (okanye "i-bulge") phakathi kwencam yosula kunye ne-tube groove.Khangela kwakhona useto lwakho loxinzelelo lomngundo.Ukuba i-comb ikwindawo echanekileyo ngokubhekiselele kwi-tube groove, faka uxinzelelo oluncinci kwi-matrix yoxinzelelo ukutyhala ityhubhu kwi-matrix yokugoba kwaye uncede ukugulisa imibimbi.
Uluhlu lwe-Wiper luza kwiintlobo ezahlukeneyo zeemilo kunye nobukhulu.Unokuthenga i-rectangular / i-square wiper yokufa kwimibhobho yoxande kunye neyesikwere, kwaye ungasebenzisa ii-wipers ze-contour / shaped ukuze ulungele iimilo ezithile kunye nokuxhasa iimpawu ezizodwa.
Ezona ndlela zimbini zixhaphakileyo sisiqhekeza esinye isikweri-ngasemva sematriki sokusula kunye nesibambi esinebladed wiper.I-square back wiper iyafa (jonga umfanekiso wesi-3) zisetyenziselwa iimveliso ezinodonga olubhityileyo, ukugoba kwe-D emxinwa (ngokuqhelekileyo i-1.25D okanye ngaphantsi), i-aerospace, izicelo eziphezulu zobuhle, kunye nemveliso yebhetshi encinci ukuya kwephakathi.
Kwiigophe ezingaphantsi kwe-2D, ungaqala nge-square-backed wiper die, ulungelelanisa inkqubo.Umzekelo, ungaqala nge 2D square back curved scraper enento eludongeni ye 150. Kungenjalo, ungasebenzisa isibambi se-scraper esine-blade yezicelo ezinobundlongondlongo ezifana ne-2D curves enento yodonga lwe-25.
Iipleyiti zokwesula ngasemva zesikwere zibonelela ngenkxaso ephezulu kwiradiyasi yangaphakathi.Basenokusikwa emva kokunxitywa kweengcebiso, kodwa kuya kufuneka ulungelelanise umatshini ukuze uvumelane ne-wiper emfutshane yokufa emva kokusika.
Olunye uhlobo oluqhelekileyo lwe-scraper blade holder lungabizi kwaye lunendleko ngakumbi ekwenzeni ukugoba (jonga umfanekiso 4).Zingasetyenziselwa ukugoba okuphakathi ukuya kwi-tight D, kunye nokugoba imibhobho eyahlukeneyo enobubanzi obufanayo obungaphandle kunye ne-CLR.Nje ukuba uqaphele ukunxitywa kweengcebiso, ungayibuyisela.Xa usenza oku, uya kuqaphela ukuba incam isetelwe ngokuzenzekelayo kwindawo efanayo neblade yangaphambili, okuthetha ukuba akufuneki uhlengahlengise ukunyuswa kwengalo ye-wiper.Qaphela, nangona kunjalo, ukuba ubumbeko kunye nendawo yesitshixo se-blade kwisibambi se-matrix esicocekileyo sahlukile, ngoko kufuneka uqinisekise ukuba uyilo lweblade luhambelana noyilo lwesibambi sebrashi.
Abaphathi be-Wiper abafakelwayo banciphisa ixesha lokumisela kodwa abakhuthazwa kwi-radii encinci.Kananjalo azisebenzi ngeetyhubhu ezixande okanye zesikwere okanye iiprofayili.Zombini iikama zokusula ii-square ngasemva kunye nokufaka iingalo zokusula zinokuveliswa kufutshane.I-wiper dies engaqhagamshelwanga iyilelwe ukunciphisa inkunkuma yombhobho, ivumela ubude obufutshane bokusebenza ngokwandisa uncamathiselo emva kwe-wiper kunye nokuvumela i-collet (ibloko yesikhokelo ityhubhu) ibekwe kufutshane kwindawo yokugoba (jonga uMfanekiso 5).
Injongo kukunciphisa ubude bombhobho ofunekayo, ngaloo ndlela ugcina izinto eziphathekayo kwisicelo esichanekileyo.Ngelixa ezi wiper zingathinteliyo zinciphisa inkunkuma, zibonelela ngenkxaso encinci kune-square ngasemva yee-wipers okanye i-standard wiper mounts ngeebrashi.
Qinisekisa ukuba usebenzisa eyona nto ingcono ye-scraper die material.Ubhedu lwe-aluminiyam kufuneka lusetyenziswe xa kugotywa izinto eziqinileyo ezifana nentsimbi engatyiwa, i-titanium kunye ne-INCONEL alloys.Xa ugoba izinto ezithambileyo ezifana nentsimbi ethambileyo, ubhedu kunye ne-aluminium, sebenzisa intsimbi okanye i-chrome wiper yensimbi (jonga umzobo 6).
Umzobo 2 Ngokuqhelekileyo, izicelo ezingaphantsi ezinobundlobongela azidingi i-chip yokucoca.Ukufunda le tshathi, bona izitshixo ezingentla.
Xa usebenzisa isiphatho somela ngencakuba, umqheba udla ngokwenziwa ngentsimbi, kodwa kwezinye iimeko zombini umqheba kunye nencam inokufuneka ibe yi-aluminiyam yobhedu.
Nokuba usebenzisa ikama okanye isibambi sebhrashi esineencakuba, uya kuba usebenzisa umatshini ofanayo wokuseta.Ngelixa ubambe ityhubhu kwindawo egxininiswe ngokupheleleyo, faka i-scraper phezu kwe-bend kunye nomva wombhobho.I-wiper tip iya kungena endaweni ngokubetha ngasemva kwi-wiper array nge-mallet yerabha.
Ukuba awukwazi ukusebenzisa le ndlela, sebenzisa iliso lakho kunye nerula (umlawuli) ukufaka i-matrix yokucima okanye i-wiper blade holder.Qaphela kwaye usebenzise umnwe wakho okanye i-eyeball ukuze uqinisekise ukuba incam ilungile.Qinisekisa ukuba incam ayikho phambili kakhulu.Ufuna inguqu egudileyo njengoko ityhubhu idlula incam ye-matrix ye-wiper.Phinda inkqubo njengoko kuyimfuneko ukufezekisa ukugoba okusemgangathweni.
I-engile yeraki yi-engile ye-squeegee ngokumalunga ne-matrix.Ezinye izicelo zobuchwephesha kwi-aerospace kunye nezinye iindawo zisebenzisa ii-wipers eziyilwe ngokuncinci ukuya kungabikho iiraki.Kodwa kwizicelo ezininzi, i-angle yokuthambeka ihlala ibekwe phakathi kwe-1 kunye ne-2 degrees, njengoko kubonisiwe kwifig.1 ukunika imvume eyaneleyo yokunciphisa ukutsala.Kuya kufuneka uqikelele ngokuthe ngqo ukuthambeka ngexesha lokuseta kunye nokujika kovavanyo, nangona ngamanye amaxesha unokuseta kujiko lokuqala.
Ukusebenzisa i-matrix ye-wiper esemgangathweni, seta i-wiper incam kancinane emva kwe-tangent.Oku kushiya indawo yokuba umsebenzisi ahambise incam yesicoci phambili njengoko inxiba.Nangona kunjalo, ungaze unyuse isicatshulwa sematrix ngokucokisekileyo okanye ngaphaya;oku kuyakonakalisa incam yematrix ecocekileyo.
Xa ugoba izinto ezithambileyo, ungasebenzisa iirakhi ezininzi njengoko ufuna.Nangona kunjalo, ukuba ugoba izinto ezinzima ezifana nensimbi engenasici okanye i-titanium, zama ukugcina i-scraping die kwi-slope encinci.Sebenzisa izinto ezinzima ukwenza i-scraper iqonde ngokusemandleni, oku kuya kunceda ukucoca ii-creases kwii-curves kunye ne-straights emva kwee-curves.Ukuseta okunjalo kufuneka kwakhona kubandakanye i-mandrel eqinile.
Ngowona mgangatho ugobileyo, i-mandrel kunye ne-scraper die kufuneka isetyenziswe ukuxhasa ingaphakathi lokugoba kunye nokulawula ngaphandle kokujikeleza.Ukuba isicelo sakho sibiza i-squeegee kunye ne-mandrel, sebenzisa zombini kwaye awuyi kuzisola.
Ukubuyela kwingxaki yangaphambili, zama ukuphumelela ikhontrakthi elandelayo yeendonga ezincinci kunye ne-CLR exineneyo.Ngesikhuseli sokungunda endaweni, ityhubhu yehla kumatshini ngokugqibeleleyo kungekho mibimbi.Oku kubonisa umgangatho ofunwa lishishini, kwaye umgangatho yinto efanelwe lishishini.
