Pane nzira dzinoverengeka dzekupeta kana kuparadzira muromo pane cylindrical chikamu. Semuenzaniso, izvi zvinogona kuitwa uchishandisa muchina kana orbital molding muchina. Nekudaro, dambudziko nemaitiro aya (kunyanya yekutanga) nderekuti zvinoda simba rakawanda.
Izvi hazvina kunaka kune dzakatetepa-madziro akakomberedzwa kana zvikamu zvinogadzirwa kubva kushoma ductile zvinhu. Kune aya maapplication, nzira yechitatu inobuda: profiling.
Kufanana ne orbital uye radial kuumba, kukunguruka inzira isiri-inokanganisa yekutonhora kuumba simbi. Nekudaro, pachinzvimbo chekugadzira musoro weposvo kana rivet, maitiro aya anogadzira curl kana mupendero pamucheto kana rimu rehollow cylindrical piece. Izvi zvinogona kuitwa kuchengetedza chimwe chikamu (chakadai sebhengi kana chivharo) mukati mechimwe chikamu, kana kungobata panoperera chubhu yesimbi kuti ive yakachengeteka, kuvandudza chimiro chayo, kana kuita kuti zvive nyore kuisa chubhu. pakati pechubhu yesimbi. chimwe chikamu.
Mukugadzira orbital uye radial, musoro unoumbwa uchishandisa sando musoro wakasungirirwa kune chinotenderera chinotenderera, icho panguva imwe chete chinoshandisa simba rekudzika pasi pane workpiece. Paunenge uchinyora, ma roller akati wandei anoshandiswa pachinzvimbo chenozzles. Musoro unotenderera pa300 kusvika 600 rpm, uye imwe neimwe yeroller inosundidzira zvinyoro nyoro uye inotsvedza zvinhu kuita isina musono, yakasimba chimiro. Mukuenzanisa, maitiro ekugadzira track anowanzo mhanya pa1200 rpm.
"Orbital uye radial modes ari nani kune akasimba rivets. Zviri nani kune tubular zvikamu, "akadaro Tim Lauritzen, chigadzirwa chekushandisa mainjiniya kuBalTec Corp.
Ma rollers anoyambuka workpiece pamwe chete nemutsara chaiwo wekubatana, zvishoma nezvishoma achigadzira zvinhu muchimiro chaidiwa. Izvi zvinotora 1 kusvika 6 seconds.
"[Nguva yekuumba] zvinoenderana nechinhu, kuti inoda kufambiswa kusvika papi uye kuti zvinhu zvinoda kuumbwa sei geometry," akadaro Brian Wright, mutevedzeri wemutungamiri wekutengesa kuOrbitform Group. "Iwe unofanirwa kufunga nezvekukora kwemadziro uye kusimba kwepombi."
Mupumburu unogona kuumbwa kubva kumusoro kusvika pasi, pasi kusvika kumusoro kana kumativi. Chinodiwa chete kupa nzvimbo yakakwana yezvishandiso.
Iyi nzira inogona kugadzira zvinhu zvakasiyana-siyana, zvinosanganisira ndarira, mhangura, aluminium yakakanda, simbi yakapfava, high carbon steel, uye simbi isina tsvina.
"Cast aluminium chinhu chakanaka chekugadzira roll nekuti kupfeka kunogona kuitika panguva yekugadzira," anodaro Lauritzen. “Dzimwe nguva zvinofanirwa kuzora mafuta kuitira kuti isasakara. Isu takagadzira hurongwa hwekuzora ma roller paanenge achigadzira zvinhu. "
Roll forming inogona kushandiswa kugadzira madziro ari 0.03 kusvika 0.12 inches gobvu. Iyo dhayamita yemachubhu inosiyana kubva 0.5 kusvika 18 inches. "Mazhinji maapplication ari pakati pe1 uye 6 inches mudhayamita," Wright anodaro.
Nekuda kwechimwe chikamu chetorque, kuumba roll kunoda 20% kushoma kudzika simba kugadzira curl kana mupendero pane crimper. Naizvozvo, maitiro aya akakodzera zvinhu zvisina kusimba senge akakanda aluminium uye zvinhu zvinonzwisa tsitsi zvakaita semasensa.
“Kudai waizoshandisa muchina wokudhinda kugadzira chubhu, ungada simba rakapetwa kashanu sokunge waizoshandisa kugadzira roll,” anodaro Wright. “Masimba epamusoro anowedzera zvakanyanya njodzi yekuwedzera kwepombi kana kukotama, saka maturusi ave kuoma uye anodhura.
Kune marudzi maviri emisoro yeroller: static roller misoro uye misoro yakataurwa. Misoro yemusoro ndiyo inonyanya kutaurwa. Iine vertically oriented mipumburu mavhiri ari preset chinzvimbo. Simba rekugadzira rinoshandiswa vertically kune workpiece.
Kusiyana neizvi, musoro wepivot une ma roller akatwasuka akaiswa pamapini anofamba zvakaenzanirana, senge chuck shaya dzechibhorani. Zvigunwe zvinofambisa roller radially mune yakaumbwa workpiece panguva imwe chete ichiisa clamping mutoro kugungano. Rudzi urwu rwemusoro runobatsira kana zvikamu zvegungano zvakabuda pamusoro pegomba repakati.
"Rudzi urwu runoshandisa simba kubva kunze mukati," Wright anotsanangura. "Unogona kupinza mukati kana kugadzira zvinhu zvakaita seO-ring grooves kana undercuts. Musoro wekutyaira unongofambisa chishandiso kumusoro nekudzika pamwe neZ axis. "
Iyo pivot roller yekugadzira maitiro inowanzoshandiswa kugadzira mapaipi ekuisirwa kutakura. "Iyi nzira inoshandiswa kugadzira groove kunze kwechikamu uye ridge rinoenderana mukati mechikamu chinoshanda sechinomira chakasimba chekutakura," Wright anotsanangura. “Zvino, kana fanicha yapinda, unoumba magumo echubhu kuchengetedza faniro. Kare, vagadziri vaifanira kucheka pfudzi muchubhu sechimbo chakasimba. ”
Kana yakashongedzwa neseti yekuwedzera yemukati inogadziriswa rollers, iyo swivel joint inogona kuumba ese ekunze nemukati dhayamita yeworkpiece.
Ingave yakamira kana yataurwa, yega yega roller uye roller musoro musangano itsika inogadzirwa kune chaiyo application. Zvisinei, musoro we roller unotsiviwa nyore nyore. Muchokwadi, iwowo muchina wekutanga unogona kuita njanji kuumba uye kutenderera. Uye senge orbital uye radial kuumba, roll kuumba inogona kuitwa seyakamira-yega semi-otomatiki maitiro kana kubatanidzwa mune yakazara otomatiki musangano system.
Iwo ma roller anogadzirwa nesimbi yakaomeswa uye anowanzo kubva pa1 kusvika 1.5 inches mudhayamita, Lauritzen akadaro. Huwandu hwema rollers mumusoro hunoenderana nehupamhi uye zvinhu zvechikamu, pamwe nehuwandu hwesimba rinoshandiswa. Inonyanya kushandiswa ndeye-tatu-roller imwe. Zvikamu zvidiki zvingangoda ma roller maviri, nepo zvikamu zvakakura kwazvo zvingada matanhatu.
"Zvinoenderana nekushandiswa, zvichienderana nekukura uye dhayamita yechikamu uye kuti unoda kufambisa zvinhu zvakadii," akadaro Wright.
"Makumi mapfumbamwe neshanu muzana ezvikumbiro ari pneumatic," akadaro Wright. "Kana uchida basa remukamuri rakanyatsojeka kana rakachena, unoda masisitimu emagetsi."
Mune zvimwe zviitiko, mapedhi ekumanikidza anogona kuvakwa muhurongwa hwekushandisa pre-mutoro kune chikamu chisati chaumbwa. Mune zvimwe zviitiko, mutsara unosiyana unosiyanisa transformer inogona kuvakwa mukati meiyo clamping pad kuyera kureba kwechikamu chisati chasangana secheki yemhando.
Iwo akakosha akasiyana mukuita uku axial simba, radial simba (munyaya yearticulated roller kuumba), torque, kutenderera kumhanya, nguva uye kutamiswa. Aya marongero achasiyana zvichienderana nechikamu saizi, zvinhu, uye bond simba zvinodiwa. Kufanana nekutsikirira, orbital uye radial kugadzira mashandiro, kuumba masisitimu anogona kuve akashongedzerwa kuyera simba uye kutamiswa nekufamba kwenguva.
Vatengesi vezvishandiso vanogona kupa nhungamiro pane yakakwana ma paramita pamwe negwara rekugadzira chikamu preform geometry. Chinangwa ndechekuti zvinhu zvitevere nzira yekushomeka kushoma. Kufamba kwezvinhu hakufanire kudarika chinhambwe chinodiwa kuchengetedza kubatana.
Muindasitiri yemotokari, nzira iyi inoshandiswa kuunganidza solenoid mavharuvhu, sensor housings, cam vateveri, bhora majoini, shock absorbers, mafirita, pombi dzemafuta, pombi dzemvura, vacuum pumps, hydraulic valves, tie rods, airbag assemblies, steering columns, uye antistatic shock absorbers Vhara mabhureki akawanda.
"Isu nguva pfupi yadarika takashanda pane imwe application apo takagadzira kepisi yechrome pamusoro pekuisa shinda kuti tiunganidze nati yemhando yepamusoro," anodaro Lauritzen.
Mutengesi wemotokari anoshandisa roll forming kuchengetedza mabearings mukati mecast aruminiyamu yepombi yemvura. Iyo kambani inoshandisa zvindori zvekuchengetedza kuchengetedza mabearings. Rolling inogadzira mubatanidzwa wakasimba uye inochengetedza mutengo wemhete, pamwe nenguva uye mari yekugezera mhete.
Muindasitiri yemidziyo yekurapa, profiling inoshandiswa kugadzira majoini eprosthetic uye catheter matipi. Muindasitiri yemagetsi, profiling inoshandiswa kuunganidza mamita, zvigadziko, capacitors uye mabhatiri. Aerospace assemblers anoshandisa roll forming kugadzira mabearings uye poppet valves. Tekinoroji iyi inotoshandiswa kugadzira mabhuraketi echitofu chemisasa, mabhureki etafura, uye mapombi ekuisa.
Inenge 98% yekugadzira muUnited States inobva kumabhizinesi madiki uye epakati nepakati. Join Greg Whitt, Process Improvement Manager kuRV mugadziri MORryde, naRyan Kuhlenbeck, CEO wePico MES, pavanenge vachikurukura kuti mabhizinesi epakati angafamba sei kubva pamanyorero kuenda kudhijitari kugadzira, kutangira pauriri hwechitoro.
Nharaunda yedu yakatarisana nematambudziko asina kumboitika ehupfumi, magariro uye zvakatipoteredza. Management consultant uye munyori Olivier Larue anotenda kuti hwaro hwekugadzirisa akawanda ematambudziko aya hunogona kuwanikwa munzvimbo inokatyamadza: iyo Toyota Production System (TPS).
