Nkhani - Momwe Mungapangire Mano Oyenera a Tsamba Lanu la Saw

Pankhani yodula macheka m'mafakitale, masamba a macheka nthawi zambiri amasokonezedwa ndi zinthu wamba zogwiritsidwa ntchito. Komabe, kwa mainjiniya odziwa bwino ntchito kapena oyang'anira kupanga, tsamba la macheka ndi chida chopangidwa mwaluso. Ubwino wa zotsatira zodula nthawi zambiri umadalira kusintha kwa madigiri awiri kapena atatu okha mu mawonekedwe a dzino, zomwe zingayambitse kusweka kwakukulu kwa tsamba la macheka kapena kupangitsa kuti pamwamba pake pakhale posalala ngati galasi.

Nthawi ino tikuyang'ana kwambiri mawonekedwe a ngodya za mano odulidwa, ndikuwonetsa momwe mawonekedwe enieni a mano amakhudzira kuchuluka kwa kutentha, kuchuluka kwa zipilala ndi mtundu wa kudula kwa mitundu itatu yayikulu ya zinthu: zitsulo zachitsulo (zodula zouma), matabwa ndi zinthu zopangidwa ndi zomangamanga.

Kapangidwe ka Dzino

Tisanayang'ane ntchito zinazake, tiyenera kusintha mawu athu okhudzana ndi miyeso itatu yofunika kwambiri ya angular yomwe imafotokoza momwe kudula kumagwirira ntchito.

Mzere wa Rake ndi ngodya ya nkhope ya dzino poyerekeza ndi mzere wozungulira womwe umatengedwa kuchokera pakati pa tsamba mpaka kumapeto kwa dzino.

Ntchito:Zimazindikira "kuuma" kwa chodulidwacho. Zimalamulira ngodya ya shear plane—ngodya yomwe zinthuzo zimasokonekera ndikulekanitsidwa ndi chogwirira ntchito.

Lamulo la Chala Chachikulu:Ma angles abwino kwambiri amafuna mphamvu zochepa koma amapanga mapeto olimba komanso olimba pang'ono. Ma angles oipa amafuna mphamvu zambiri koma amapereka mphamvu zowongolera komanso mphamvu zambiri m'mphepete.

Ngodya Yotseguka (Ngodya Yothandizira) —β

Uwu ndi bevel pamwamba pa dzino lomwe lili kutali ndi m'mphepete mwa dzino.

Ntchito yake ndikuletsa nsonga za carbide kuti zisakwiyitse pa zinthu zomwe mwangodula kumene.

Nayi njira yosinthira:Ngati ngodya ili yolimba kwambiri, nsonga za dzino zimakhala zofooka komanso zopanda chithandizo, zomwe zimapangitsa kuti ziphwanye. Ngati ili yocheperako kwambiri, kukangana kumabweretsa kutentha kwambiri, zomwe zimapangitsa kuti kutentha kutukuke ndipo pamapeto pake kuwotcha ntchito.

Chipatala cha Radial (Mbali)

Ngodya iyi imachepetsera dzino kuyambira kutsogolo kupita kumbuyo m'mbali.

Imachepetsa kukangana pakati pa mbali za mano ndi makoma a kerf (malo odulira). Pa ntchito zodulira zouma pomwe palibe mafuta oziziritsira mbali za mano, ngodya iyi ndi yofunika kwambiri poletsa kutentha kuti kusakunjikane.

Zitsulo za Ferrous (Chotsukira Chozizira Chodulidwa)

Kuyang'ana Kwambiri: Kuyang'anira Kutentha ndi Kukana Kukhudzidwa

Macheka ozizira odulidwa mouma (okhala ndi nsonga za cermet kapena carbide yokutidwa) ndi gulu lovuta kwambiri kupanga. Ndipo cholinga chake ndi ichi: tikufuna kupanga kutentha, koma tiyenera kuchotsa nthawi yomweyo.

Pakudula kouma, kutentha kumapangidwa ndi kusintha kwa pulasitiki kwa chitsulo. Maonekedwe a chidacho ayenera kusamutsa pafupifupi 80% mpaka 90% ya kutentha kumeneko kupita ku tchipisi—motere, tsamba ndi chogwirira ntchito zimakhalabe zozizira. Umu ndi momwe mfundo ya "kudula kozizira" imagwirira ntchito.

Jiometri ya "Cold Cut"

Podula chitsulo chopepuka, nthawi zambiri timagwiritsa ntchito njira yopukusira zitsulo zitatu (TCG). Koma ngodya imasiyana malinga ndi kapangidwe ka chitsulocho.

Kugwiritsa Ntchito Makoma Opyapyala (Machubu, Angle Iron, Ma Channels)

Ngodya ya Rake: Zabwino (+5° mpaka +10°)

Ngodya Yochotsera: 10° mpaka $12°

Kuganizira:Mpata wokwera pang'ono umathandiza dzino kutuluka bwino lomwe ladulidwa popanda kukoka chibowo chomwe chimapangidwa mkati mwa chubu.

Kugwiritsa Ntchito Kolimba (Mipiringidzo Yokhala ndi Bar, Mbale Yokhuthala)

Ngodya ya Rake: Zero mpaka Low Zabwino 0° mpaka +3°

Fiziki:Mukadula chitsulo cholimba, dzino limagwira ntchito ndi chinthucho kwa nthawi yayitali, zomwe zimapangitsa kuti katunduyo azigwira ntchito mosalekeza komanso mwamphamvu. Ngodya yakuthwa yamphamvu imasiya nsonga ya carbide yopanda chithandizo komanso yofooka.Ngodya ya Zero Rakeimatsogolera mphamvu zodulira kumbuyo kulowa m'thupi la tsamba, pogwiritsa ntchito mphamvu yokakamiza ya carbide (yomwe ndi yayitali) m'malo mwa mphamvu yake yodula (yomwe ndi yotsika).

Ngodya Yolowera: 8°

Kuganizira:Ngodya yocheperako imawonjezera "nyama" yambiri kumbuyo kwa m'mphepete mwa msewu, imagwira ntchito ngati chotenthetsera kutentha komanso chothandizira kapangidwe kake.

Chitsulo Chosapanga Dzimbiri (Vuto Lolimbitsa Ntchito)

Ngodya ya Rake: 0°mpaka +5°
Kuganizira Mwapadera:Chitsulo chosapanga dzimbiri (monga SUS304) chimakonda "kugwira ntchito molimbika" ngati chikakwezedwa.yenerakudula, osati kutsetsereka. Ngakhale kuti zero rake imapereka mphamvu, nthawi zambiri timafunika lalikulu pang'onoNgodya Yoyeretsera (12)°)kuposa momwe zimagwiritsidwira ntchito pa chitsulo chofewa. Izi zimatsimikizira kuti pambuyo podula, kumbuyo kwa dzino sikukhudza chinthucho, chomwe "chimabwerera" pang'ono chifukwa cha kulimba kwake.

Mapulogalamu Opangira Matabwa

Kuyang'ana Kwambiri: Kutsogolera Tirigu ndi Kudula Ulusi

Matabwa ndi chinthu chopangidwa ndi anisotropic—makhalidwe ake enieni amasiyana malinga ndi momwe mphamvu imayendera poyerekeza ndi tirigu. Chifukwa chake, mawonekedwe a tsamba la macheka ayenera kusinthasintha malinga ndi tirigu.

A. Kung'amba (Kudula ndi Tirigu)

Kung'amba kwenikweni ndi ntchito yocheka. Cholinga chake ndi kuchotsa ulusi wautali.
- Ngodya ya Rake: Zabwino Kwambiri (+20)°mpaka +25°)
- Jiyomethri: Kupukutira Pamwamba Pang'ono (FTG)
- Fiziki:Ngodya yayitali ya mbedza imagwira ntchito ngati chingwe cholunjika, kutulutsa zinthu mwachangu. Ngodya yolimba iyi imakoka matabwa mu tsamba. Ngakhale izi zimathandiza kuti chakudya chizidya mofulumira kwambiri (chofunika kwambiri pa matabwa odulira mitengo), imasiya mawonekedwe osalala.
- Chinthu Chokhudza Mitsempha ya M'mimba:"Gullet" (chigwa pakati pa mano) chiyenera kukhala chakuya komanso chachikulu. Ulusi wautali wa tirigu umapanga zidutswa zazikulu; ngati gullet ndi yaying'ono kwambiri, udzu wa utuchi umakanikirana, kupanga kukangana ndikuwotcha matabwa (ndi tsamba).
B. Kudula Mtanda (Kudula Pakati pa Tirigu)

Kuduladula kumafuna kudula ulusi womwe uli wolunjika kudulako. Ngati mugwiritsa ntchito tsamba lodula (FTG) apa, "lidzaphulika" kapena kuswa matabwa omwe ali mbali yotulukira.
- Ngodya ya Rake: Zabwino Pakati (+10)°mpaka +15°)
- Jiyomethri: Chovala Chokwera Chapamwamba Chosiyana (ATB) kapena Hi-ATB
- Fiziki:Mano ake amapindika kuti apange mfundo zofanana ndi mpeni mbali zosiyanasiyana. Amalemba ulusi kumanzere ndi kumanja kwa kerf.isanafikekuchotsa zinthu zapakati. Ngodya yapansi ya rake (10)°motsutsana ndi 20°) amachepetsa "kugwira" kwa tsamba, zomwe zimathandiza kuti kudula kukhale kosalala komwe kumasiya njere yosalala.

Zopanda Feri ndi Zosakaniza

Kuyang'ana Kwambiri: Chitetezo ndi Kukana Kutupa

A. Aluminiyamu ndi Zitsulo Zosakhala ndi Feri

Aluminiyamu ndi yofewa, yofewa, ndipo imasungunuka pang'ono. Imadziwika kuti ndi "yosalala" ndipo nthawi zambiri imatseka mano a masamba.
- Ngodya ya Rake: Zoipa (-5)°mpaka -6°)
- Jiyomethri: TCG
- Fiziki ya Chitetezo:Ngati mugwiritsa ntchito ngodya yolumikizira bwino (monga tsamba la matabwa) pa aluminiyamu, tsambalo "lidzakwera" pa chinthucho. Mu chocheka chodula ndi manja, ichi chikhoza kukoka mwamphamvu chogwirira cha chocheka pansi kapena kuponya chogwirira ntchito.Rake Woipangodya imasintha mphamvu ya vekitala: imakankhira zinthuzokutalikuchokera pa tsamba ndi ku mpanda wakumbuyo, kuonetsetsa kuti kudulako kuli kotetezeka komanso kolamulidwa.
- Mafuta odzola:Mosiyana ndi kudula kouma kwachitsulo, aluminiyamu nthawi zambiri imafuna mafuta odzola kuti tchipisi zisalumikizidwe ku m'mimba.
B. Zopangira Zomangamanga (Zopaka, Melamine, Simenti ya Ulusi)
- Ngodya ya Rake: Zoyipa (-2)°mpaka -5°)
- Fiziki:Zipangizo monga Melamine zimakhala ndi chophimba cholimba ngati galasi pamwamba pake chofewa. Chingwe chabwino chimakweza chinthucho mmwamba, zomwe zimapangitsa kuti pamwamba pake pofewa pazidutswa zing'ambike.Chingwe Choyipaamakanikiza zinthuzo pansi panthawi yodula, kukanikiza pamwamba pake ndikuletsa kusweka.
- Chidziwitso cha Zinthu:Pa simenti ya ulusi (yomwe imakhala ndi silika wambiri), ngodya yake ndi yofunika kwambiri kuposa nsonga ya chinthucho.Daimondi ya Polycrystalline (PCD)nsonga ndizofunikira kuti munthu akhale ndi moyo wautali, nthawi zambiri zimakhala ndi ma angles otsika (+5)°) kuti azitha kuyang'anira fumbi lolemera.
