Mafotokozedwe apadera a mankhwala.makulidwe ndi 8-50mm, m'lifupi 150-625mm, kutalika 5-15m, ndi specifications mankhwala ali pafupi mipata kukwaniritsa zosowa za owerenga, ndipo angagwiritsidwe ntchito m'malo mbale sing'anga, popanda kudula, ndipo akhoza mwachindunji welded.
Pamwamba pa mankhwalawa ndi owala komanso oyera.Njira yowonongeka kwa madzi othamanga kwambiri imagwiritsidwa ntchito kachiwiri.
Mbali ziwirizo ndi zoimirira ndipo ngodya zake ndi zomveka bwino.Kudutsa kwachiwiri kwa vertical rolling mu kugubuduza bwino kumatsimikizira kupendekeka kwabwino kwa mbali zonse ziwiri, ngodya zomveka bwino komanso khalidwe labwino la mbali.
Mulingo wa mankhwalawo ndi wolondola, kusiyana kwa mfundo zitatu ndi kusiyana kwa msinkhu womwewo ndikwabwino kuposa chitsulo chachitsulo;mankhwalawo ndi athyathyathya komanso owongoka, ndipo mawonekedwe a mbale ndi abwino.Kugubuduza mwatsatanetsatane kumagwiritsa ntchito njira yopititsira patsogolo, kuwongolera kwamanja kwamanja kuonetsetsa kuti palibe chitsulo chosakanizika komanso kukoka chitsulo, kulondola kwambiri kwazinthuzo, kulolerana, kusiyana kwa mfundo zitatu, kusiyana komweko, kupindika kwa chikwakwa ndi magawo ena abwino kuposa sing'anga. mbale, ndi mbale kuwongoka ndi zabwino.Kumeta ubweya wozizira, kulondola kwakukulu kwa kutalika kwake.
Zogulitsa zimatengera muyezo wadziko lonse, wofanana ndi mbale yachitsulo.Miyezo yaubwino ndiukadaulo imakonzedwa ndikupangidwa molingana ndi YB/T4212-2010 muyezo (Q345B/Q235B imanena za GB/T1591-94, motsatana.
1. Chitsulo chowotcha chotentha ndi chitsulo chachitali, chotheka chogudubuzika chokhala ndi gawo lalikulu la makona atatu kuti chigwiritsidwe ntchito.Mafotokozedwe ake amawonetsedwa mu millimeters of thickness * wide.Chitsulo chophwanyika chikhoza kumalizidwa zitsulo, zogwiritsidwa ntchito pazigawo, makwerero, milatho ndi mipanda, etc. Chitsulo chophwanyika chingagwiritsidwenso ntchito ngati ma billets ndi slabs kwa zitsulo zotsekemera ndi pepala laminated.(Zinthu: Q215, Q235), kukhazikitsa muyezo: GB704-1988 m'malo GB704-83, muyezo uwu umakhudza makulidwe a 3 ~ 60mm, m'lifupi 10 ~ 200mm, amakona anayi mtanda gawo la ambiri cholinga otentha-anagulung'undisa lathyathyathya zitsulo .Mkhalidwe wotumizira: Chitsulo chathyathyathya chimaperekedwa muzitsulo zowongoka.Muyezo: Chitsulo chathyathyathya chautali wokhazikika komanso kutalika kwa anyamata kumaperekedwa ndi kulemera kwake.
2. chitsulo chopukutira chathyathyathya chimapangidwa ndi mbale yachitsulo yayitali yokhala ndi gawo lamakona anayi.Forging sangathe kupeza mawonekedwe ndi kukula kwa forgings, komanso akhoza kwambiri kusintha kuponyedwa zitsulo bungwe, kusintha kachulukidwe zitsulo;akhoza kusintha kugawa kwa fiber bungwe, kuchotsa anisotropy, kukonza makina azitsulo, kuti mphamvu ndi kulimba kwazitsulo zikhale bwino;ndipo akhoza kukonzedwa pulasitiki ndi m'munsi mu mkulu zitsulo ndi mkulu aloyi zitsulo.Chitsulo chokhazikika chathyathyathya chimakhala chitsulo chamtundu wapamwamba kwambiri, chomwe chimagwiritsidwa ntchito ngati akasupe, zida ndi zida zofunika kwambiri zamakina.Mafotokozedwe a chitsulo chonyezimira chathyathyathya amawonetsedwa mu makulidwe * m'lifupi, ndipo mawonekedwe ake ndi 20mm * 40mm ~ 160mm * 300mm.muyezo kuphedwa: GB/T16761-1
Chitsulo chachigawo ndi chimodzi mwa mitundu inayi yayikulu yazitsulo (mbale, chubu, mtundu, waya).Malingana ndi mawonekedwe a chigawocho, chigawo chachitsulo chimagawidwa kukhala chitsulo chosavuta chagawo ndi zitsulo zovuta zagawo (gawo zitsulo).Zakale zimatanthawuza zitsulo zozungulira, zitsulo zozungulira, zitsulo zosalala, zitsulo za ngodya, zitsulo za hexagonal, etc.;omaliza amatanthauza I-mtengo, chitsulo njira, njanji zitsulo, zenera chimango zitsulo, kupinda chitsulo, etc.
Square zitsulo - lalikulu gawo zitsulo, otentha adagulung'undisa ndi ozizira adagulung'undisa;otentha adagulung'undisa lalikulu mbali zitsulo kutalika 5-250mm;ozizira-kokedwa lalikulu mbali zitsulo kutalika 3-100mm.
Chitsulo chozungulira - chigawo chozungulira chachitsulo, chogawidwa kukhala chotentha chopiringidwa, chopukutira ndi chozizira katatu, chotentha chozungulira chitsulo chozungulira 5-250mm, chomwe 5-9mm chimagwiritsidwa ntchito ngati zipangizo zopangira waya wachitsulo, wotchedwa waya ndodo. ;monga mu mbale kupereka amatchedwanso otentha adagulung'undisa koyilo.Chitsulo chopangidwa mozungulira chozungulira chimakhala chokhuthala, chomwe chimagwiritsidwa ntchito ngati shaft billet.Zozizira zozungulira zitsulo m'mimba mwake 3-100mm, kulondola kwapamwamba kwambiri.
Ngongole zitsulo - ogaŵikana mitundu iwiri ya zitsulo ofanana ndi wosafanana ngodya.Mafotokozedwe a zitsulo za ngodya amasonyezedwa ndi kukula kwa kutalika kwa mbali ndi makulidwe a mbali.Kawirikawiri mfundo za ngodya zitsulo zopangidwa ndi No. 2-20, mwachitsanzo, chiwerengero cha masentimita a kutalika kwa mbali.Monga No. 5 equilateral ngodya zitsulo zimene amanena za mbali kutalika kwa 5cm (50mm) ngodya zitsulo.Nambala yofanana ya ngodya nthawi zambiri imakhala ndi makulidwe a 2-7 osiyanasiyana.
Njira yowerengera kulemera kwachitsulo chokhazikika
Lathyathyathya zitsulo: kulemera kwa mita = 0.00785 * makulidwe * mbali m'lifupi
