1.1 pulasitiki
Pulasitiki ndi kuthekera kwazinthu zachitsulo kupanga mapindikidwe apulasitiki (mapindikidwe okhazikika) pansi pa katundu popanda kuwonongeka.
1.2 Kuuma
Kuuma ndi cholozera pamlingo wa kuuma kapena kufewa kwa zinthu zachitsulo.Njira yodziwika kwambiri yodziwira kuuma pakupanga ndi indentation hardness njira, yomwe imagwiritsa ntchito inndenter ya geometry inayake kukanikizira pamwamba pa chitsulo choyesedwa pansi pa katundu wina ndikuzindikira kuuma kwake molingana ndi kuchuluka kwa kukakamizidwa. mu izo.
Njira zomwe zimagwiritsidwa ntchito kwambiri ndi Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) ndi njira za Vickers hardness (HV).
1.3 Kutopa
Mphamvu, pulasitiki ndi kuuma zomwe takambirana kale ndizomwe zimalozera kuzinthu zamakina achitsulo pansi pa katundu wokhazikika.M'malo mwake, zida zambiri zamakina zimagwira ntchito mozungulira mozungulira, ndipo m'mikhalidwe yotereyi ziwalo zimatulutsa kutopa.
1.4 Kulimba kwamphamvu
Katundu womwe umagwira pamakina pa liwiro lalikulu umatchedwa mphamvu yamphamvu, ndipo kuthekera kwachitsulo kukana kuwonongeka kwa katundu kumatchedwa kulimba kwamphamvu.
1.5 Mphamvu
Mphamvu ndi kukana kwa chitsulo chachitsulo kuti chiwonongeke (kuwonongeka kwakukulu kwa pulasitiki kapena kupasuka) pansi pa katundu wosasunthika.Monga katundu kanthu mu mawonekedwe a kumakoka, psinjika, kupinda, kukameta ubweya, kotero mphamvu imagawidwanso mu mphamvu kumakoka, compressive mphamvu, kupinda mphamvu, kukameta ubweya mphamvu, etc.. Nthawi zambiri pali kugwirizana pakati pa mphamvu zosiyanasiyana, kugwiritsa ntchito mphamvu yamphamvu yokhazikika ngati cholozera champhamvu kwambiri.
Square chubu ntchito yomanga, kupanga makina, ntchito zomanga zitsulo, shipbuilding, thandizo mphamvu dzuwa, zomangamanga zitsulo, zomangamanga mphamvu, zomera mphamvu, ulimi ndi mankhwala makina, galasi nsalu yotchinga makoma, galimoto chassis, ndege, kukatentha moto, njanji njanji. , kumanga nyumba, zombo zoponderezedwa, akasinja osungira mafuta, milatho, zida zopangira magetsi, makina onyamula ndi zonyamula ndi zina zambiri zowotcherera zigawo zamapangidwe, etc.
Gulu la ndondomeko
Square chubu amagawidwa molingana ndi ndondomeko kupanga: otentha adagulung'undisa msokonezo lalikulu chubu, ozizira kukokedwa msokonezo lalikulu chubu, extruded opanda lalikulu chubu, welded lalikulu chubu.
Pakati pawo, welded lalikulu chubu lagawidwa mu
1. molingana ndi ndondomekoyi - arc kuwotcherera square chubu, kukana kuwotcherera square chubu (high frequency, otsika pafupipafupi), kuwotcherera mpweya lalikulu chubu, ng'anjo kuwotcherera lalikulu chubu
2. molingana ndi kuwotcherera msoko - molunjika msoko welded lalikulu chitoliro, ozungulira welded lalikulu chitoliro.
Gulu lazinthu
Square chitoliro ndi zinthu: kumveka mpweya zitsulo lalikulu chitoliro, otsika aloyi lalikulu chitoliro.
1. Plain mpweya zitsulo anawagawa: Q195, Q215, Q235, SS400, 20 # zitsulo, 45 # zitsulo, etc.
2. Chitsulo chochepa cha alloy chimagawidwa kukhala: Q345, 16Mn, Q390, ST52-3, etc.
Zopanga muyeso classification
Square chubu molingana ndi mfundo kupanga: dziko muyezo lalikulu chubu, Japanese muyezo lalikulu chubu, mfumu lalikulu chubu, American muyezo lalikulu chubu, European muyezo lalikulu chubu, sanali muyezo lalikulu chubu.
Gawo la mawonekedwe
Square chubu malinga ndi mawonekedwe a gulu gulu.
1. Gawo losavuta lalikulu chubu: chubu lalikulu, chubu lalikulu la rectangular.
2. Chigawo chovuta chachubu: chubu lalikulu la maluwa, chubu lotseguka, chubu lalikulu lamalata, chubu chowoneka bwino.
Gulu lamankhwala apamwamba
Square chubu malinga ndi mankhwala pamwamba: otentha kuviika kanasonkhezereka lalikulu chubu, electro galvanized lalikulu chubu, wopaka mafuta chubu, kuzifutsa lalikulu chubu.
Gwiritsani ntchito magulu
Square chubu ndi ntchito: kukongoletsa lalikulu chubu, zida zida square chubu, makina makampani lalikulu chubu, makampani mankhwala lalikulu chubu, zitsulo kapangidwe lalikulu chubu, shipbuilding lalikulu chubu, magalimoto lalikulu chubu, zitsulo mtengo square chubu, cholinga chapadera lalikulu chubu.
Gulu makulidwe a khoma
Machubu a square amasankhidwa ndi makulidwe a khoma: chubu chachikulu champanda lalikulu, chubu chapakati pakhoma ndi chubu chocheperako.
