Xa iinjineli zichaza a rollformers shaft ifektri roller, abagcini nje uku-odola inxalenye-baqinisekisa umqolo ojikelezayo we-high-cycle metal forming line. Siye sabona ukumiswa kwemveliso okuninzi okubangelwa zii-shaft rollers ezijike emva kwe-3,000 yeemitha ze-coil feed eqhubekayo, okanye ukukhangela ukuqina komphezulu okusilelayo kwi-58 HRC. Yiyo loo nto ukuchaneka kungakhethi apha-yinto esisiseko.
Kutheni ii-Shaft Rollers zisilela-kwaye yintoni eneneni esebenzayo
Uninzi lweentsilelo lulandela oonobangela abathathu: ubume besinyithi obungahambelaniyo, ukukhukuliseka okulinganayo ngexesha lokukhwela ibhayisekile, kunye nokungonelanga komphezulu wemfezeko phantsi konxibelelwano olurhabaxa. Iirola zentsimbi eziqhelekileyo zekhabhoni ziyaqhekeka phantsi koxinzelelo lokugoba ngokuphindaphindiweyo kwiindawo zokumisa. Ukugalela okudityanisiweyo ngaphandle kokucocwa okuziinkozo okulawulwayo kuphuhlisa iintanda ezincinci kufutshane neendlela eziphambili. Kwaye ukutshintshwa koomatshini be-CNC bahlala betsiba ukukhululeka koxinzelelo lwasemva komatshini-ke bagqwethe kwiiyure ezingama-48 zofakelo.
Sivavanya yonke i-shaft roller yokuqina kwe-torsional sisebenzisa iiprothokholi ze-ASTM E143-kwaye sikhaba nayiphi na iyunithi ebonisa> 0.012 mm i-radial runout kwi-3,000 rpm. Ukuqinisekiswa kwehlabathi lokwenyani kubaluleke ngaphezu kweenkcazo zekhathalogu. Omnye umatshini wokusila wetyhubhu waseMntla waseMelika uxele i-47% yobomi benkonzo obude emva kokutshintsha ukusuka kwi-AISI 4140 yegeneric ukuya kwi-AMS 5387 cobalt-nickel alloy rollers yethu, nangona le yokugqibela ixabisa i-2.3 × ngaphezulu ngaphambili. I-ROI yavela ekupheliseni ukutshintshwa kweveki kunye nokuphepha ixesha lokuphumla elingacwangciswanga ngexesha lokuqhuba umbhobho wokukhupha iimoto.
Ukudityaniswa okuthe nkqo kuSombulula into engenakukwazi ukukhutshwa ngaphandle
Awukwazi ukukhupha i-metallurgical control. Xa umthengi ethumela umzobo we-GD & T we-215 mm OD × 1,850 mm ubude be-winch centre shaft roller-ene-± 0.005 mm cylindricity, i-62-65 HRC yobunzima bomhlaba, kunye nokulandelelwa ngokupheleleyo kwi-MTRs-udinga ukuphosa, umatshini, kunye nonyango lokushisa phantsi kophahla olulodwa. Akukho handoffs. Akukho bhetshi idibanisayo.
Isixhobo sethu esithobela i-ISO sisebenza kuzo zontathu:
- Ukugalelwa kwesanti yentsimbi ye-ductile kunye nezindlu zensimbi ezingenasici kunye namazinga okupholisa alawulwayo ukukhusela i-nodular graphite clustering
- I-Multi-axis CNC ukujika kunye nokusila yeeshafu ezilukhuni-ukusebenzisa ukuqinisekiswa kwe-CMM ekuqhubekeni emva kokurhabaxa, ukugqitywa kwesiqingatha, kunye nokupasa kokugqibela
- Ngokwenza lukhuni + ukwenziwa lukhuni komphezulu, iqinisekiswe nge-Rockwell C-scale cross-sections rhoqo nge-150 mm ubude
Oku kuphelisa i-classic "i-gap ye-foundry-to-machine-shop": apho ukucutha kwe-shrinkage kungabalwa kwi-machining stock allowances, okanye apho ukuphathwa kobushushu kuphazamisa imilinganiselo yokugqiba kwangaphambili. Siye sanciphisa ukusebenza ngokutsha kwii-roller eziyinkimbinkimbi nge-68% ukususela ekuphunyezweni kwembuyekezo ye-thermal evaliweyo kwiinkqubo zethu ze-CNC.
UKhetho lweMathiriyeli AyiloMthambo wePhepha eliKhethekileyo
"Intsimbi engenasici" ayithethi nto ngaphandle komxholo. Iirolaformers ezisebenza ngentsimbi okanye i-abrasive-coated steel, i-304SS inxiba ngaphantsi kweeyure ezingama-800. I-T800 yethu ye-cobalt-based alloy rollers ihlala ngaphezulu kweeyure ezingama-5,200-kuba i-carbide dispersion yabo iyaxhathisa i-galling, kungekhona nje ukubola. Kwaye i-AMS 5387 ayisiyiyo nje "i-cobalt alloy" -yinkqubo ye-Co-Ni-Cr-Mo-W elungelelaniswe ngokuchanekileyo eyenzelwe ukugcinwa kobunzima obushushu ngaphezulu kwe-600 ° C, ibaluleke kakhulu xa i-friction yokufudumala i-spikes ngexesha lokwenziwa kwesantya esiphezulu.
Sifumana ii-ingots ezikrwada kuphela kwii-mills eziqinisekisiweyo ukuya kwi-AMS 2301 kunye ne-EN 10204 3.1, kunye nokulandeleka okugcweleyo kobushushu. Ibhetshi nganye yenziwa uhlalutyo lwe-spectrographic phambi kokusaswa-kwaye sigcina iisampulu iminyaka eli-10. Ukuba umthengi unika ingxelo yokunxiba kwangaphambi kwexesha, sitsala i-MTR yasekuqaleni, siyithelekise ngokuchasene neyona ndawo incinci ye-microstructure (nge-SEM/EDS), kwaye sikhethe ukuba ngaba umcimbi wawuyinto, inkqubo, okanye ukungasebenzisi isicelo.
Ukuthembeka Kuqala Phambi KokuSika Kokuqala
A ethembekileyo rollformers shaft ifektri roller ayilindi ukuba imizobo ifike. Isebenza kwangoko-kuphononongo loyilo. Sihlala sifola imiba efana nemitha yemitha engaphantsi egxininisa uxinizelelo kwizihlalo ezithweleyo, okanye ukunganyamezeli indlela engundoqo ebangela ukunxitywa okukhathazayo. Kunyaka ophelileyo, siye sanceda i-OEM yaseMzantsi-mpuma ye-Asia ihlaziya i-geometry yegxalaba kwi-shaft ye-rolling-stand-12-ukunciphisa i-peak von Mises uxinzelelo nge-31% kunye nokwandisa ubomi bokudinwa ngaphaya kwe-10.7 imijikelo.
Uzinzo lonikezelo lulandela kucwangciso olubhityileyo—hayi izithembiso. Silandelelanisa ukugalela, imithwalo yokuphatha ubushushu, kunye neeshedyuli zoomatshini kwiibhloko zeeyure ezi-4. Iiodolo zePrototype zithunyelwa ngeentsuku ze-18; umthamo womthamo ophakathi ubambe kwiifestile zeentsuku ezi-±2. Akukho ntlawulo zikhawulezayo. Akukho "phantsi kokufumaneka kwezinto" amagatya. Ngenxa yokuba ukuthembeka akukhona nje malunga nokuba yintoni eyinyani-imalunga nento efika ngexesha, rhoqo.
Kwiinjineli ezichaza amacandelo apho ukungaphumeleli kumisa imigca yokuvelisa, ukhetho alukho phakathi kwabathengisi-kuphakathi kweengcinga kunye nobungqina. Iirola zeshaft ezichanekileyo zifuna intsebenziswano echanekileyo. Oko kuqala nge-metallurgy onokuthi uyiqinisekise, iinkqubo onokuthi uziphicothe, kunye neziphumo onokuthi uzilinganise-kungekhona nje kwii-microns, kodwa ngexesha.
