Mukamva 'zodzigudubuza shaft roller', anthu ambiri nthawi yomweyo amangojambula chodzigudubuza chokhachokha—silinda yachitsulo yolimba, mwina yokhala ndi ma bere. Ndiko kulakwitsa koyamba. Kunena zoona, ndi dongosolo. Ntchitoyi imadalira mgwirizano pakati pa zitsulo za shaft, mapeto a roller pamwamba ndi kuuma kwa mbiri, ndi kulolerana kwa msonkhano. Ndawona machitidwe ambiri akungoyang'ana pa zodzigudubuza za OD, ndiye ndikudabwa chifukwa chake amavala msanga kapena kugoletsa mbiri. Mphepete, yomwe nthawi zambiri imaganiziridwa pambuyo pake, ndipamene zolephera zambiri zimayambira. Si pini chabe; ndi dynamically yodzaza chigawo chimodzi.
Kusankha Zinthu Zakuthupi Si Masewera Ongoyerekeza
Kumayambiriro kwa nthawi yanga ndikugwira ntchito ndi mizere ya rollform, tinali ndi vuto lobwerezabwereza ndi linalake rollformers shaft roller seti yomwe imagwiritsidwa ntchito popanga ngalande zachitsulo zamphamvu kwambiri. Zodzigudubuza, zopangidwa kuchokera ku chitsulo chodziwika bwino cha D2, zidakhazikika bwino, koma tidapitilirabe kukumana ndi shaft. Osati breakage, kungopindika kokwanira kuponya kulolerana kwa mbiri pambuyo pa maola angapo akuthamanga. Lingaliroli nthawi zonse linkafunika shaft yayikulu yokulirapo, yomwe idapangitsa kuti pakhale zovuta zokonzanso nyumba.
Kukonzekera kwenikweni kunachokera ku kusintha kwakuthupi kwa shaft palokha. Tinasintha kuchoka ku chitsulo chokhazikika cha 4140 kupita ku aloyi yolimba kwambiri ya 4340, tikugwira ntchito ndi wothandizira yemwe amamvetsa kutopa kwa katundu. Ichi sichinali chigamulo chochokera m'ndandanda; idachokera pakuwunika mawonekedwe ophwanyika komanso kayendedwe ka micro pampando wonyamula. Malo ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd. khalani ndi maziko a izi. Ndi zaka zoposa 30 akuponya ndi kupanga makina, amapeza shaft kuti ikhale yolemetsa shaft roller sikungotembenuzidwa ku bar katundu. Nthawi zambiri imayenera kukhala yopangidwa mwachinyengo kapena yosasunthika bwino kuti iwonetsetse kuti mbewu imayenda bwino, kenako imapangidwa kuti igwirizane ndi zomwe zingalole. Ntchito yawo yokhala ndi ma aloyi apadera monga ma aloyi opangidwa ndi faifi ndi yofunikira pano-nthawi zina, chifukwa cha malo ovuta, muyenera kuyang'ana kupyola magiredi achitsulo.
Izi zimabweretsa nuance ina: mawonekedwe. Mipando yonyamula shaft nthawi zambiri imakhala pansi, koma ma radii osinthira amakhala ovuta. Ngodya yakuthwa ndi cholumikizira kupsinjika chomwe chikudikirira kuti apange poyambira ming'alu. Tinaphunzira kulongosola ndi kuyang'ana ma radii awa mosamala. Ndi kachidutswa kakang'ono pajambula komwe kumapangitsa kusiyana kwakukulu pakati pa nthawi yolephera.
The Harder is Better Fallacy for Rollers
Pali nthano yodziwika kuti kukulitsa kuuma kwa pamwamba pa roller mpaka max (titi, 65 HRC ndi pamwambapa) kumapereka moyo wautali kwambiri. Ndi msampha wokwera mtengo. Za odzigudubuza odzigudubuza, makamaka zomwe zimapanga zida zomatira kapena zonyezimira (monga zitsulo zina zamalati), malo olimba kwambiri amatha kukhala osalimba. M'malo movala mokongola, imatha kupukuta kapena kupukuta, kuwononga nthawi yomweyo pepalalo.
Ndikukumbukira pulojekiti yomwe tinali kupanga zitsulo za aluminiyamu-bronze. Zinthu zake zinali ngati gummy. Gulu lathu loyamba la odzigudubuza linali lolimba kwambiri. Iwo sanali kuvala; amangodzaza ndi zinthu, kunyamula aloyi pamwamba pake kenako ndikusindikizanso zolakwika pamzere. Yankho lake linali lotsutsana: tidagwiritsa ntchito chodzigudubuza chofewa pang'ono chokhala ndi chopukutidwa, pafupifupi ngati galasi komanso mankhwala apadera kuti achepetse ndulu. Kuvala kumayendetsedwa ndi njira yosiyana - mafuta onunkhira osati kuuma koopsa.
Apa ndipamene luso lapadera la makina ndi kumaliza limafunikira. Kampani ngati QSY, yomwe ili ndi luso lakuya la CNC makina opangira nkhungu, imatha kupanga zodzigudubuza zokhala ndi njira zoziziritsira mkati (zofunikira pakuthamanga kwambiri) komanso mawonekedwe owongolera. Kutha kugwira ntchito ndi chitsulo chosapanga dzimbiri kapena ma aloyi opangidwa ndi cobalt kumatsegula zitseko zopangira zida zowononga kapena zotentha kwambiri zomwe ma roller zitsulo za kaboni sangathe kuzigwira.
Kuchita Zokwanira: The Make or Break Tolerance
Izi zitha kukhala gawo logwira ntchito kwambiri, loyipa kwambiri pantchitoyo, koma kupeza kokwanira kolakwika pa a shaft roller kusonkhanitsa kudzawononga ntchito yanu yonse yabwino pazipangizo. Sikuti kungokanikizira tsinde pa shaft. Pali kulingalira kwa kutentha ndi kuganiziridwa kwa zone ya katundu. Pamakonzedwe osasunthika, mufunika chosokoneza chomwe chili chokwanira kuti muteteze kukwawa koma osalemera kwambiri kotero kuti chimadzaza mochulukira kapena kusokoneza mpikisano wamkati.
Nthawi ina tinasonkhanitsa ma roller atsopano pazitsulo zomwe bukuli linanena kuti ndizoyenera. Pansi pa katundu ndi kutentha kwa ntchito, shaft inakula mokwanira kuti ipangike pang'ono. Chotsatira chake sichinali kulephera koopsa; kunali kugwedezeka kosalekeza, kwafupipafupi komwe kumawonekera ngati mafunde obisika muzinthu zopangidwa. Zinatitengera masiku ozindikira kuti tibwererenso kumayendedwe ang'onoang'ono. Kukonzaku kunali kusintha kokwanira kosankha kutengera miyeso yeniyeni yoyezedwa pa kutentha kolamulidwa, osati kungosindikiza kwadzidzidzi.
Kwa nyumba yonyamula mu roller yokha, kulolerana kumakhala kosavuta. Zothina kwambiri, ndipo mumayika pachiwopsezo chomanga chogudubuza chikatenthedwa. Zotayirira kwambiri, ndipo mumapeza sewero lomwe limatanthawuza molakwika mawonekedwe. Awa ndi gawo la makina olondola. Sizongokhudza kugunda nambala; ndi za kusasinthika kudutsa gulu lonse la odzigudubuza kwa mzere wamagulu angapo. Kuthekera kogwira chakhumi (0.0001 mainchesi) mosadukiza, monga mungayembekezere kuchokera kwa wopanga makina a CNC, sikungangokambirana.
Kuphatikiza ndi Kuyesa Kwapadziko Lonse
Mutha kukhala ndi zida zamtundu uliwonse - shaft yopangidwa bwino kwambiri yochokera ku aloyi ya premium, chogudubuza chokhala ndi kulimba koyenera ndi kumalizidwa, ndi zonyamula zolondola - ndikulepherabe dongosolo. Kuphatikiza ndikofunika. Kodi chodzigudubuza chimatenthedwa bwanji? Kodi ndi gawo lopakidwa mafuta, losindikizidwa kwa moyo wonse (lofala koma lopanda kutentha), kapena lili ndi makonzedwe a nkhungu yamafuta osalekeza? Chisankhocho chimalamula mapangidwe amkati a rollformers shaft roller.
Tinaphunzira izi pa mzere wofolerera wothamanga kwambiri. Mafotokozedwe amalingaliro onse anali olondola. Koma pochita, kutentha kwa kutentha kuchokera kumapangidwe kosalekeza pa 150 mapazi pamphindi kunali kwakukulu kuposa momwe ankayembekezera. Mafuta mu mayendedwe muyezo anasweka, kutsogolera kutenthedwa ndi khunyu. Kukonzanso kumaphatikizapo kufotokozera ma roller okhala ndi mawonekedwe otseguka ndikuphatikiza makina apakati amafuta amafuta mu chimango cha rollformer. Miyendoyo inkafunika timizera ta mafuta opingasa. Zinali zoopsa za retrofit zomwe zikadakhala zophweka ngati ntchito yowona yamafuta ikaganiziridwa kuyambira pachiyambi.
Ichi ndichifukwa chake ma prototyping ndi kuyezetsa pansi pa katundu sangalowe m'malo. Wothandizira yemwe samangopereka gawoli koma amatha kulangiza pakuphatikizana kwamakina kutengera sayansi yakuthupi komanso luso lopanga makina amawonjezera phindu lalikulu. Mwachitsanzo, podziwa kuti chipolopolo chopanda chipolopolo chopanda kanthu chikhoza kukupatsani maonekedwe abwino kwambiri a mawonekedwe ovuta kusiyana ndi opangidwa, kapena kuti alloy yopangidwa ndi faifi ndi ofunika mtengo wa kukhazikika kwake kwa kutentha mu ntchito yanu, imachokera zaka zambiri pansi, osati pepala logulitsa.
Kusanthula Kulephera Monga Chida Chophunzirira
Osataya cholephera odzigudubuza odzigudubuza kapena kutsinde osatsegula kaye. Kufa kwakufa ndiye maphunziro abwino kwambiri. Ndimasunga malo osungira zinthu zomwe zidalephera muofesi yanga. Mtsinje umodzi udawonetsa kutopa kwachikale kochokera pachizindikiro cha makina pamalo osafunikira kwambiri - phunziro lofotokoza kumalizidwa kwa shaft yonse, osati mipando yokhayo. Wodzigudubuza wina adawonetsa mavalidwe apadera mbali imodzi yokha, ndikulozera kumayendedwe olakwika pamalo omwe sitinawagwire ndi zizindikiro zoyimba.
Kulephera kumodzi kochititsa chidwi kwambiri kunali chodzigudubuza chomwe chinang'ambika mozungulira. Mlandu woyamba unali pa zofooka zakuthupi. Kusanthula kwa Metallurgical, komwe tidachita ndi labu yakunja (ngakhale opanga ena ophatikizika ngati QSY ali ndi izi m'nyumba chifukwa cha maziko awo oyambira), adawonetsa kuti zinthuzo zinali zabwino. Mng'aluyo adawonetsa kupsinjika kwambiri kwa hoop. Chifukwa chake? Dongosolo la hydraulic lotsekera chogudubuza pa shaft linali kukakamiza kwambiri kuposa momwe linapangidwira, makamaka kupanga kusokoneza komwe kumalimbitsa khoma logudubuza. Kukonzekera kunali kosavuta kukakamiza wowongolera.
Zochitika izi zimapanga ndondomeko yowonjezereka ya pragmatic. Tsopano, poyitanitsa, kukambirana sikungokhudza miyeso ndi mtundu wazinthu. Zimakhudza kugwiritsa ntchito: zinthu zopangidwa, liwiro la mzere, njira yothira mafuta, matani oyembekezeredwa, ndi kayendedwe kasamalidwe. Imasandutsa kugula kwazinthu kukhala ntchito yothandizana ndi uinjiniya, momwe mungakwaniritsire kudalirika komanso kutsika mtengo pantchito yosinthira.
