Pamene mainjiniya amatchula a fakitale ya rollformers shaft roller, sikuti amangoyitanitsa gawo-amateteza msana wozungulira wa mzere wopangira zitsulo zapamwamba. Tawona kuyimitsidwa kochulukira kopangidwa chifukwa cha ma shaft roller omwe adasokonekera pambuyo pa 3,000 metres a chakudya chokhazikika cha ma coil, kapena kulephera kuwunika kuuma kwa pamwamba pa 58 HRC. Ichi ndichifukwa chake kulondola sikuli kosankha apa - ndiye maziko.
Chifukwa Chake Ma Shaft Roller Amalephera—Ndipo Zomwe Zimagwira Ntchito
Zolephereka zambiri zimayambira pazifukwa zitatu: zitsulo zosagwirizana, kutengeka pang'onopang'ono panthawi yotentha, komanso kusakhulupirika kwapamtunda pokhudzana ndi abrasive. Standard mpweya zitsulo zodzigudubuza kusweka pansi mobwerezabwereza kupinda kupsyinjika mu rollforming maimidwe. Ma alloyed castings popanda kuwongolera bwino kwambewu kumapanga ming'alu yaying'ono pafupi ndi ma keyways. Ndipo zosintha zamakina a CNC nthawi zambiri zimalumpha mpumulo wapambuyo popanga makina - kotero amasokoneza mkati mwa maola 48 akhazikitsa.
Timayesa shaft roller iliyonse kuti ikhale yolimba pogwiritsa ntchito ma protocol a ASTM E143 - ndikukana gawo lililonse lomwe likuwonetsa > 0.012 mm radial runout pa 3,000 rpm. Kutsimikizika kwapadziko lonse lapansi ndikofunikira kwambiri kuposa zolemba zamakalata. Mphero imodzi yaku North America chubu idati 47% moyo wautali wautumiki atasintha kuchoka ku AISI 4140 kupita ku AMS 5387 cobalt-nickel alloy rollers, ngakhale yomaliza idawononga 2.3 × zambiri kutsogolo. ROI idachokera pakuchotsa zololeza zonyamula mlungu uliwonse ndikupewa kutsika kosakonzekera panthawi yothamangitsa mapaipi amoto.
Kuphatikiza Koyima Kumathetsa Zomwe Kutulutsa Sizingatheke
Simungathe kutulutsa zowongolera zazitsulo. Wogula akatumiza chojambula cha GD&T cha 215 mm OD × 1,850 mm kutalika kwa winch center shaft roller-yokhala ndi ± 0.005 mm cylindricity, 62-65 HRC pamwamba kuuma, ndi traceability zonse ku MTRs - mumafunika kuponyera, makina, ndi kutentha mankhwala pansi pa denga limodzi. Palibe ma handoffs. Palibe kusagwirizana kwamagulu.
Malo athu ogwirizana ndi ISO amathandizira onse atatu:
- Kuponya mchenga za chitsulo cha ductile ndi zitsulo zosapanga dzimbiri zokhala ndi mitengo yoziziritsa yoyendetsedwa bwino kuti muteteze kusakanikirana kwa ma nodular graphite
- Multi-axis CNC kutembenuka ndikupera za ma shaft olimba - kugwiritsa ntchito kutsimikizira kwa CMM mutatha kusokoneza, kumaliza, komanso kupita komaliza.
- Kupyolera mu kuumitsa + kulowetsa pamwamba kuumitsa, yotsimikiziridwa ndi magawo amtundu wa Rockwell C pa 150 mm kutalika kwake
Izi zimachotsa "mpata wopeza makina opangira makina": pomwe kuchepa kwapang'onopang'ono sikumawerengeredwa popereka ndalama zogulira zinthu, kapena pomwe kupotoza kwa kutentha kumalepheretsa miyeso yomaliza. Tachepetsa kukonzanso kwa ma roller ovuta ndi 68% kuyambira pomwe tidakhazikitsa chipukuta misozi chotseka pamapulogalamu athu a CNC.
Kusankha Zinthu Zofunika Sizinthu Zochita Mwapadera
"Chitsulo chosapanga dzimbiri" sichitanthauza kanthu popanda nkhani. Kwa odzigudubuza omwe ali ndi zitsulo zokhala ndi malata kapena zokutira, 304SS imavala mkati mwa maola 800. Ma rollers athu a T800 okhala ndi cobalt amakhala opitilira maola 5,200 - chifukwa kubalalitsidwa kwawo kwa carbide kumalimbana ndi ndulu, osati dzimbiri. Ndipo AMS 5387 sikuti ndi "cobalt alloy" yokha - ndi njira yofananira bwino ya Co-Ni-Cr-Mo-W yopangidwa kuti isunge kuuma kotentha pamwamba pa 600 ° C, yofunikira kwambiri pakuwotcha kwamakangana pakapangidwe kothamanga kwambiri.
Timapeza ma ingots aiwisi okha kuchokera ku mphero zovomerezeka kupita ku AMS 2301 ndi EN 10204 3.1, zokhala ndi kutentha kwathunthu. Gulu lililonse limawunikiridwa musanawonyedwe - ndipo timasunga zitsanzo kwa zaka 10. Ngati kasitomala anena kuti wavala msanga, timakoka MTR yoyambirira, ndikuiyerekeza ndi gawo lenileni (kudzera pa SEM/EDS), ndikudzipatula ngati vutolo linali lakuthupi, ndondomeko, kapena kusagwirizana kwa ntchito.
Kudalirika Kumayamba Asanayambe Kudula Kwambiri
A odalirika fakitale ya rollformers shaft roller samadikirira kuti zojambula zifike. Zimagwira ntchito koyambirira - pakuwunikanso mapangidwe. Nthawi zambiri timayang'ana zinthu ngati fillet radii yocheperako yomwe imayang'ana kwambiri mipando, kapena kusalolera kwa makiyi omwe amapangitsa kuvala kovutitsa. Chaka chatha, tidathandiza Southeast Asian OEM kukonzanso mapewa a geometry pa shaft yoyimilira 12-kuchepetsa kupsinjika kwa von Mises ndi 31% ndikukulitsa moyo wotopa kupitilira 10.7 mikombero.
Kukhazikika kwa kaperekedwe kumatsatiridwa ndi kulinganiza kosasunthika—osati malonjezo. Timatsata kutsanulira, kutenthetsa kutentha, ndi ndondomeko zamakina mu midadada ya maola 4. Prototype imayitanitsa sitima m'masiku 18; mawindo apakati-voliyumu amagwira mawindo amasiku ± 2. Palibe ndalama zofulumira. Palibe "kutengera kupezeka kwa zinthu". Chifukwa kudalirika sikungokhudza zomwe zimachitika zoona-komanso zomwe zimafika pa nthawi yake, nthawi zonse.
Kwa mainjiniya omwe amafotokozera magawo omwe kulephera kumayimitsa mizere yopanga, kusankha sikuli pakati pa ogulitsa-ndi pakati pa zongoganiza ndi umboni. Zodzigudubuza za Precision shaft zimafuna maubwenzi olondola. Izi zimayamba ndi zitsulo zomwe mungatsimikizire, njira zomwe mungayang'anire, ndi zotsatira zomwe mungathe kuziyeza, osati mu ma microns, koma mu nthawi.
