Welded zitsulo chitoliro ndi seamed zitsulo chitoliro.Kupanga kwake ndikupinda chubu chopanda kanthu (mbale yachitsulo ndi chingwe chachitsulo) kukhala chubu chokhala ndi mawonekedwe ofunikira pagawo ndi kukula mwa njira zosiyanasiyana zopangira, ndiyeno gwiritsani ntchito njira zowotcherera zowotcherera pamodzi.Njira yopezera mapaipi achitsulo.
Poyerekeza ndi chitoliro chosasunthika chachitsulo ndi chitoliro chowotcherera, chimakhala ndi mawonekedwe amtundu wapamwamba kwambiri, makamaka makulidwe a khoma, zida zosavuta zazikulu, zopondapo zazing'ono, ntchito yosalekeza yopanga, kupanga zosinthika, ndi mitundu yonse yamagulu a unit.
Mmodzi, The ndondomeko yopanga ozungulira zitsulo chitoliro ali pafupifupi motere:
1. The zopangira za ozungulira zitsulo chitoliro ndi strip zitsulo koyilo, kuwotcherera waya ndi flux.
2. Asanayambe kupanga, chitsulo chowongolera chimakonzedwa, chokonzedwa, chokonzedwa, chotsuka pamwamba, chonyamulidwa ndi kupindika.
3. The weld gap control chipangizo ntchito kuonetsetsa kuti kuwotcherera kusiyana amakwaniritsa zofunika kuwotcherera, ndi m'mimba mwake chitoliro, misalignment ndi kuwotcherera kusiyana mosamalitsa.
4. Pambuyo podula mipope imodzi yachitsulo, mapaipi achitsulo atatu oyambirira a gulu lirilonse ayenera kuyang'anitsitsa dongosolo loyamba loyang'ana kuti ayang'ane makina, mankhwala, mawonekedwe a ma welds, khalidwe lapamwamba la mipope yachitsulo ndi kuyesa kosawononga. kuonetsetsa kuti ndondomeko yopanga chitoliro ndi yoyenera.Pambuyo pake, ikhoza kukhazikitsidwa mwalamulo kupanga.
Chachiwiri, chitoliro chowongoka chamsoko wowongoka wa arc welded:
Chitoliro chowongoka cha arc welded chitoliro (LSAW) nthawi zambiri chimagwiritsa ntchito mbale zachitsulo ngati zopangira, ndipo zimapanga njira zosiyanasiyana zopangira mapaipi otchingidwa ndi mbali ziwiri zowotcherera arc ndi kukulitsa m'mimba mwake.
Zida zazikuluzikulu zikuphatikizapo makina ophera m'mphepete, makina opindika, makina opangira, makina opangira zitsulo, makina owonjezera awiri, etc. Pa nthawi yomweyo, kupanga njira za LSAW mapaipi akuphatikizapo UO (UOE), RB (RBE), JCO. (JCOE), etc. Chitsulo chachitsulo chimakanikizidwa koyamba mu mawonekedwe a U pakupanga kufa, ndiyeno kukanikizidwa mu mawonekedwe a O, ndiyeno mkati ndi kunja kulowetsedwa kwa arc kuwotcherera kumachitika.Pambuyo kuwotcherera, m'mimba mwake (Kukulitsa) kumapeto kapena kutalika konseko kumatchedwa UOE welded chitoliro, ndipo chopanda kukula kwake chimatchedwa UOE welded chitoliro.Kwa UO welded chitoliro.Chitsulo chachitsulo chimakulungidwa mu mawonekedwe (Roll Bending), ndiyeno kuwotcherera kwamkati ndi kunja kwa arc kumachitika.Pambuyo kuwotcherera, m'mimba mwake ndi kukodzedwa mu RBE welded chitoliro kapena RBE welded chitoliro popanda kukula m'mimba mwake.Chitsulo mbale aumbike mu dongosolo la JCO-mtundu, ndipo pambuyo kuwotcherera, awiriwo kukodzedwa mu JCOE welded chitoliro kapena JCO welded chitoliro popanda kukula m'mimba mwake.
Njira yopangira chitoliro cha UOE LSAW:
Njira zazikulu zitatu zopangira njira yopangira chitoliro cha UOE LSAW ndi izi: chitsulo chopindika chisanadze, U kupanga ndi O kupanga.Njira iliyonse imagwiritsa ntchito makina osindikizira apadera kuti amalize njira zitatu zokhotakhota m'mphepete mwa mbale yachitsulo, U kupanga ndi O kupanga motsatizana, ndikusintha mbale yachitsulo kukhala chubu chozungulira.
Njira yopangira mapaipi a JCOE LSAW:
Kupanga: Pambuyo popondaponda pang'onopang'ono pamakina opangira JC0, theka loyamba la mbale yachitsulo imakanikizidwa mu mawonekedwe a "J", ndiyeno theka lina la mbale yachitsulo imakanikizidwa mu mawonekedwe a "J" kuti apange. mawonekedwe a C, ndipo pamapeto pake amapanikizidwa kuchokera pakati kuti Pangani "0" mawonekedwe a chubu chotseguka.
Kuyerekeza kwa JCO ndi njira zopangira UO:
Kupanga kwa JCO ndikopanga kukakamiza kopitilira muyeso, komwe kumasintha njira yopangira chitoliro chachitsulo kuchokera ku masitepe awiri a UO kupanga masitepe angapo.Panthawi yopanga, kusinthika kwa mbale yachitsulo ndi yunifolomu, kupanikizika kotsalira kumakhala kochepa, ndipo pamwamba sipanga zokopa.
Mipope yachitsulo yokonzedwayo imakhala ndi kusinthasintha kwakukulu mu kukula ndi mawonekedwe a m'mimba mwake ndi makulidwe a khoma, ndipo imatha kupanga zinthu zazikulu ndi zazing'ono;imatha kupanga mapaipi achitsulo okhala ndi mainchesi akulu akulu-mphamvu zokhuthala, komanso kupanga mapaipi achitsulo okhala ndi mipanda yaying'ono ndi yokhuthala;makamaka popanga mapaipi apamwamba kwambiri okhala ndi mipanda, makamaka mapaipi ang'onoang'ono komanso apakati apakati, omwe ali ndi zabwino zosayerekezeka panjira zina.
Ikhoza kukwaniritsa zofunikira zambiri za ogwiritsa ntchito ponena za ndondomeko ya chitoliro chachitsulo.Ndalamazo ndizochepa, koma kupanga kwake kumakhala kochepa, ndipo kutulutsa kwapachaka ndi matani 100,000 mpaka 250,000.
Kujambula kwa UO kumapangidwa ndi U ndi O nthawi ziwiri za kukakamiza.Amadziwika ndi mphamvu zazikulu komanso kutulutsa kwakukulu.Nthawi zambiri, kutulutsa kwapachaka kumatha kufika matani 300,000 mpaka 1 miliyoni, omwe ndi oyenera kupanga misa yamtundu umodzi.
3. Molunjika msoko mkulu pafupipafupi welded chitoliro:
Chitoliro chowongoka chowongoleredwa chowongoka kwambiri (RW) ndikuwotcha ndikusungunula m'mphepete mwa chubu cha chubu pogwiritsa ntchito mawonekedwe akhungu komanso kuyandikira kwapanthawi yaposachedwa kwambiri pambuyo popanga koyilo yotentha yopangidwa ndi makina opangira, komanso kukakamiza. kuwotcherera ikuchitika pansi pa zochita za wodzigudubuza extrusion kukwaniritsa kupanga.
Welded zitsulo chitoliro, amatchedwanso welded chitoliro, ndi chitoliro zitsulo zopangidwa mbale zitsulo kapena Mzere zitsulo pambuyo crimping ndi kuwotcherera.Welded zitsulo chitoliro ali ndondomeko yosavuta kupanga, dzuwa mkulu kupanga, mitundu yambiri ndi specifications, ndi ndalama zochepa zida, koma mphamvu zake zonse ndi otsika kuposa chitoliro chosasokonezeka zitsulo.
Kuyambira m'ma 1930, ndi chitukuko mofulumira anagubuduza kupanga mosalekeza anagubuduza kupanga apamwamba Mzere zitsulo ndi kupita patsogolo kwa kuwotcherera ndi kuyendera luso, khalidwe la welds wakhala mosalekeza bwino, ndi mitundu ndi specifications welded mipope zitsulo zawonjezeka tsiku ndi tsiku. .Chitoliro chachitsulo cha msoko.Welded zitsulo mipope anawagawa mowongoka msoko mipope welded ndi mipope ozungulira welded malinga ndi mawonekedwe a weld msoko.
Gulu ndi njira yopanga: gulu la ndondomeko - chitoliro cha arc welded, chitoliro chamagetsi chowotcherera, (mafupipafupi, otsika pafupipafupi) chitoliro chowotcherera cha gasi, chitoliro chowotcherera cha ng'anjo.Kupanga kwa chitoliro chowongoka chowongoka chowongoka ndi chosavuta, kupanga bwino ndikwambiri, mtengo wake ndi wochepa, ndipo chitukuko ndi chachangu.Mphamvu ya ozungulira welded chitoliro zambiri apamwamba kuposa msoko wowongoka welded chitoliro, ndi welded chitoliro ndi awiri okulirapo akhoza kupangidwa ndi billet yopapatiza, ndi mipope welded ndi diameters osiyana akhoza kupangidwa ndi m'lifupi billet chomwecho.Koma poyerekeza ndi chitoliro chowongoka cha kutalika komweko, kutalika kwa weld kumawonjezeka ndi 30 ~ 100%, ndipo liwiro la kupanga ndilotsika.

Zopanga zamakono ndi ndondomeko
Kupanga kwa chitoliro chowongoka chowongoka chowongoka ndi chosavuta, kupanga bwino ndikwambiri, mtengo wake ndi wochepa, ndipo chitukuko ndi chachangu.Mphamvu ya ozungulira welded chitoliro zambiri apamwamba kuposa msoko wowongoka welded chitoliro, ndi welded chitoliro ndi awiri okulirapo akhoza kupangidwa ndi billet yopapatiza, ndi mipope welded ndi diameters osiyana akhoza kupangidwa ndi m'lifupi billet chomwecho.Koma poyerekeza ndi chitoliro chowongoka cha kutalika komweko, kutalika kwa weld kumawonjezeka ndi 30 ~ 100%, ndipo liwiro la kupanga ndilotsika.
Mipope yowotcherera yokhala ndi mainchesi akulu kapena mainchesi okhuthala nthawi zambiri amapangidwa mwachindunji ndi zitsulo zachitsulo, pomwe mapaipi ang'onoang'ono owotcherera ndi mipope yopyapyala yokhala ndi mipanda yopyapyala imangofunika kuwotcherera mwachindunji ndi zingwe zachitsulo.Ndiye mutatha kupukuta kosavuta, kupaka pa izo.Choncho, mipope yambiri yowotcherera yokhala ndi mainchesi ang'onoang'ono imatenga kuwotcherera kwa msoko wowongoka, ndipo mipope yambiri yowotcherera imagwiritsa ntchito kuwotcherera kozungulira.
