Kukho iindlela ezininzi zokugoba okanye ukusabalalisa umlomo kwindawo ye-cylindrical. Umzekelo, oku kunokwenziwa kusetyenziswa umatshini wokushicilela okanye umatshini wokubumba we-orbital. Nangona kunjalo, ingxaki ngezi nkqubo (ingakumbi eyokuqala) kukuba zifuna amandla amaninzi.
Oku akulunganga kwiindawo ezinodonga olucekethekileyo okanye iinxalenye ezenziwe ngezinto ezincinci ze-ductile. Kwezi zicelo, kuvela indlela yesithathu: iprofayili.
Njengokwenziwa kwe-orbital kunye ne-radial, ukuqengqeleka yinkqubo engeyiyo impembelelo yokwenza okubandayo kwesinyithi. Nangona kunjalo, endaweni yokwenza intloko yeposi okanye i-rivet, le nkqubo idala i-curl okanye i-edge kwi-edge okanye i-rim yeqhekeza elingenalutho le-cylindrical. Oku kunokwenziwa ukukhusela icandelo elinye (elifana nokuthwala okanye i-cap) ngaphakathi kwelinye icandelo, okanye nje ukunyanga isiphelo sombhobho wesinyithi ukuze ukhuseleke, uphucule ukubonakala kwayo, okanye wenze kube lula ukufaka ityhubhu. embindini wetyhubhu yentsimbi. enye inxalenye.
Kwi-orbital kunye ne-radial forming, intloko yenziwa kusetyenziswa ihamile yentloko edityaniswe kwi-spindle ejikelezayo, ethi kwangaxeshanye isebenzise amandla okuhla kwi-workpiece. Xa kusenziwa iprofayili, kusetyenziswa iiroli ezininzi endaweni yemilomo. Intloko ijikeleza kwi-300 ukuya kwi-600 rpm, kwaye ipasi nganye ye-roller ityhala ngobumnene kwaye igudise izinto zibe yinto engenamthungo, ehlala ixesha elide. Xa kuthelekiswa, imisebenzi yokwenza umkhondo idla ngokuqhutywa kwi-1200 rpm.
"Iindlela ze-Orbital kunye ne-radial zingcono kakhulu kwiirivethi eziqinileyo. Kungcono kumacandelo e-tubular, ”utshilo uTim Lauritzen, injineli yemveliso kwiBalTec Corp.
Ii-roller ziwela i-workpiece kunye nomgca ochanekileyo woqhagamshelwano, ngokuthe ngcembe ubumba izinto eziphathekayo kwimilo efunwayo. Le nkqubo ithatha malunga nemizuzwana eyi-1 ukuya kwe-6.
"[Ixesha lokubumba] lixhomekeke kwizinto eziphathekayo, ukuba kufuneka zihanjiswe kude kangakanani kwaye yintoni ijometri ekufuneka yenziwe," utshilo uBrian Wright, usekela mongameli wentengiso kwi-Orbitform Group. "Kufuneka uqwalasele ubukhulu bodonga kunye namandla okuqina kombhobho."
Umqulu unokuqulunqwa ukusuka phezulu ukuya phezulu, phantsi ukuya phezulu okanye ecaleni. Imfuneko kuphela kukubonelela ngesithuba esaneleyo sezixhobo.
Le nkqubo inokuvelisa izinto ezahlukeneyo, ezibandakanya ubhedu, ubhedu, i-aluminium ephosiweyo, intsimbi ethambileyo, intsimbi ephezulu yekhabhoni, kunye nensimbi engenasici.
"I-aluminium ephosiweyo sisixhobo esilungileyo sokwenza umqulu kuba ukunxitywa kungenzeka ngexesha lokwenziwa," utshilo uLauritzen. Ngamanye amaxesha kuye kufuneke ukuba uthambise amalungu ukuze unciphise ukuguga. Enyanisweni, siye savelisa inkqubo yokuthambisa iirola njengoko zibumba izinto.”
Ukwenziwa komqulu kungasetyenziselwa ukwenza iindonga ezinobunzima obuyi-0.03 ukuya kwi-0.12 intshi ubukhulu. Ububanzi beetyhubhu buhluka ukusuka kwi-0.5 ukuya kwi-18 intshi. "Izicelo ezininzi ziphakathi kwe-intshi e-1 kunye ne-6 ububanzi," utshilo u-Wright.
Ngenxa yecandelo le-torque eyongezelelweyo, ukuqulunqwa kwe-roll kufuna i-20% ngaphantsi kwamandla angaphantsi ukwenza i-curl okanye i-edge kune-crimper. Ke ngoko, le nkqubo ifanelekile kwizinto ezibuthathaka ezifana ne-aluminium ephosiweyo kunye namacandelo anovakalelo anje ngezinzwa.
UWright uthi: “Ukuba ubunokusebenzisa umatshini wokushicilela ukuze wenze ithubhu edityanisiweyo, kuya kufuneka ukuba ube namandla ngokuphindwe kahlanu kunokusebenzisa ukwenza imiqulu. “Amandla aphezulu anyusa kakhulu umngcipheko wokwandiswa kwemibhobho okanye ukugoba, ngoko ke izixhobo ngoku ziya zisiba nzima kwaye ziyabiza.
Kukho iintlobo ezimbini zeentloko ze-roller: iintloko ze-static roller kunye neentloko ezichazwe. Iiheader ezimileyo zezona zixhaphakileyo. Inamavili okuskrola ajonge ngokuthe nkqo kwindawo esetwe kwangaphambili. Amandla okwenza isetyenziswe ngokuthe nkqo kwi-workpiece.
Ngokwahlukileyo, intloko yepivot ineerola ezithe tyaba ezithe tyaba ezifakwe kwizikhonkwane ezihamba ngaxeshanye, njengemihlathi ye-chuck ye-drill press. Iminwe ihambisa i-roller nge-radially kwi-workpiece ebunjiweyo ngelixa kwangaxeshanye ifaka umthwalo obambezelayo kwindibano. Olu hlobo lwentloko luluncedo ukuba iinxalenye zendibano ziphuma ngaphezu komngxuma ophakathi.
“Olu hlobo lusebenza ngamandla angaphandle ngaphakathi,” uyachaza uWright. “Ungangena ngaphakathi okanye wenze izinto ezifana ne-O-ring grooves okanye undercuts. Intloko yedrayivu imane ihambisa isixhobo phezulu nasezantsi ecaleni kwe-axis ye-Z.
Inkqubo yokwenza i-pivot roller isetyenziswa ngokuqhelekileyo ukulungisa imibhobho yofakelo lokuthwala. "Le nkqubo isetyenziselwa ukudala i-groove ngaphandle kwenxalenye kunye ne-ridge ehambelanayo ngaphakathi kwendawo esebenza njengesigxina esiqinileyo sokuthwala," u-Wright uyachaza. Emva koko, xa i-bearing ingenile, ubumba isiphelo sombhobho ukuze ukhusele ukuthwala. Ngaphambili, abavelisi bekufuneka banqumle igxalaba kumbhobho njengendawo yokumisa eqinile. ”
Xa uxhotyiswe ngeseti eyongezelelweyo yeerola zangaphakathi ezilungelelanisiweyo, i-swivel joint inokwenza i-diameter yangaphandle nangaphakathi ye-workpiece.
Ingaba i-static okanye i-articulated, i-roller nganye kunye ne-roller indibano yentloko yenziwe ngokwesiko kwisicelo esithile. Nangona kunjalo, intloko ye-roller iguqulwa ngokulula. Enyanisweni, umatshini ofanayo osisiseko unokwenza umgaqo kaloliwe owenziweyo kunye nokuqengqeleka. Kwaye njengokubunjwa kwe-orbital kunye ne-radial, ukuqulunqwa komqulu kunokwenziwa njengenkqubo yokuma yodwa ye-semi-automated okanye idityaniswe kwi-automated assembly system.
Iirola zenziwe ngentsimbi yensimbi eqinile kwaye ziqhele ukusuka kwi-1 ukuya kwi-intshi eyi-1.5 ububanzi, utshilo uLauritzen. Inani lee-roller entloko lixhomekeke kubukhulu kunye nezinto eziphathekayo zenxalenye, kunye nomthamo wokusetyenziswa kwamandla. Eyona nto isetyenziswa ngokuqhelekileyo yi-three-roller. Amalungu amancinci anokufuna iirola ezimbini kuphela, ngelixa iindawo ezinkulu kakhulu zinokufuna ezintandathu.
"Kuxhomekeke kwisicelo, kuxhomekeke kubukhulu kunye nobubanzi benxalenye kunye nokuba ufuna ukuhambisa izinto ezininzi kangakanani," kusho uWright.
"Amashumi alithoba anesihlanu eepesenti zezicelo zomoya," utshilo uWright. "Ukuba ufuna ukuchaneka okuphezulu okanye umsebenzi ococekileyo wegumbi, udinga iinkqubo zombane."
Kwezinye iimeko, iipads zoxinzelelo zinokwakhiwa kwisistim ukuze kufakwe ngaphambili umthwalo kwicandelo ngaphambi kokubumba. Kwezinye iimeko, i-linear variable differential transformer inokwakhiwa kwi-clamping pad ukulinganisa ubude be-stack yecandelo ngaphambi kokuhlanganisa njengokukhangela umgangatho.
Iinguqu eziphambili kule nkqubo ziyi-axial force, i-radial force (kwimeko yokwenziwa kwe-roller edibeneyo), i-torque, isantya sokujikeleza, ixesha kunye nokufuduka. Ezi setingi ziya kwahluka ngokuxhomekeke kubungakanani benxalenye, imathiriyeli, kunye neemfuno zamandla ebhondi. Njengokucofa, ukujikeleza kunye nokusebenza kweradial, iisistim zokubumba zinokuxhotyiswa ukulinganisa amandla kunye nokufuduka ngokuhamba kwexesha.
Ababoneleli ngezixhobo banokubonelela ngesikhokelo kwiiparamitha ezizezona zifanelekileyo kunye nesikhokelo sokuyila inxalenye yejiyometri. Injongo kukuba izinto zilandele indlela yokuchasana okuncinci. Ukunyakaza kwezinto eziphathekayo akufanele kudlule umgama oyimfuneko ukukhusela uxhumano.
Kushishino lweemoto, le ndlela isetyenziselwa ukudibanisa iivalvu ze-solenoid, i-sensor housings, abalandeli becam, ii-absorbers zebhola, izihluzi, iimpompo zeoyile, iimpompo zamanzi, iimpompo ze-vacuum, iivalvu zehydraulic, iinduku zokubopha, iindibano zengxowa yomoya, iikholamu zokuqhuba, i-antistatic shock absorbers Vimba i-brake manifold.
“Kutshanje siye sasebenza kwisicelo apho siye sakha ikepusi yechrome ngaphezulu kokufakwa okufakwe imisonto ukuze sidibanise indongomane ekumgangatho ophezulu,” utshilo uLauritzen.
Umthengisi weemoto usebenzisa i-roll forming ukuze akhusele iibheringi ngaphakathi kwendlu yempompo ye-aluminiyam. Inkampani isebenzisa amakhonkco okugcina ukukhusela iibheringi. Ukuqengqeleka kudala umdibaniso owomeleleyo kwaye konga iindleko zeringi, kunye nexesha kunye neendleko zokukrola iringi.
Kwishishini lezixhobo zonyango, iprofayili isetyenziselwa ukwenza amalungu okufakelwa kunye neengcebiso ze-catheter. Kwishishini lombane, iprofayili isetyenziselwa ukudibanisa iimitha, iisokethi, ii-capacitors kunye neebhetri. Abadibanisi be-aerospace basebenzisa i-roll forming ukuvelisa iibheringi kunye ne-poppet valves. Itekhnoloji ide isetyenziswe ukwenza izibiyeli zesitovu senkampu, iziqhekeza zesarha zetafile, kunye nokufakwa kwemibhobho.
Malunga ne-98% yemveliso eMelika ivela kumashishini amancinci naphakathi. Joyina uGreg Whitt, uMphathi woPhuculo lweNkqubo kumvelisi weRV uMORryde, kunye noRyan Kuhlenbeck, i-CEO yePico MES, njengoko bexoxa ngendlela amashishini aphakathi anokuhamba ngayo ukusuka kwimanyuwali ukuya kwimveliso yedijithali, ukuqala kumgangatho wevenkile.
Uluntu lwethu lujongene nemingeni engazange ibonwe ngaphambili kwezoqoqosho, ezentlalo nezokusingqongileyo. Umcebisi woLawulo kunye nombhali u-Olivier Larue ukholelwa ukuba isiseko sokusombulula ezininzi zezi ngxaki sinokufumaneka kwindawo emangalisayo: i-Toyota Production System (TPS).
