Mugadziri wepombi dzakakora nemadziro
Sezvinoratidzwa nezita racho, square pombi imhando yesquare pombi mhando. Zvishandiso zvakawanda zvinogona kuita square pombi muviri. Inoshandiswa nechinangwa chei uye kupi. Mapaipi akawanda eskweya mapaipi esimbi. Mushure mokusunungura, kuenzanisa, crimping uye welding, vanogadzira mapaipi akatenderera, ayo anokungurutswa kuita mapaipi akaenzana, uye ozocheka muhurefu hunodiwa. Kazhinji, kune 50 square tubes pasuru. Panyaya yenzvimbo, machubhu mazhinji ari muhukuru hwakakura, kubva pa10 * 10 * 0.8-1.5 kusvika 500 * 500 * 10-25. Machubhu eskweya anoshandiswa kune zvimiro mativi machubhu, yekushongedza mativi machubhu, kuvaka square machubhu, mechanical square chubhu, nezvimwe.
Mukobvu wakakomberedzwa sikweya pombi imhando yepiipi yakakora yakakomberedzwa nesimbi ine hollow square chikamu, inozivikanwawo sesimbi inotonhora-yakaumbwa chimiro. Icho chikamu chesimbi chine sikweya chikamu chimiro uye saizi, iyo inogadzirwa neQ235 inopisa-yakatenderedzwa kana kutonhora-yakatenderedzwa tambo kana coil seyakadzika zvinhu, kutonhora kubhenda uye yakakwirira-frequency welding. Pamusoro pekukobvura kwemadziro, saizi yekona uye kumucheto kufuratira kwekupisa-yakakungurutswa yakawedzera gobvu madziro sikweya pombi inosvika kana kutopfuura mwero wekudzivirira welding inotonhora yakagadzirwa sikweya pombi.
Makobvu akakomberedzwa square machubhu anoshandiswa mukuvaka, kugadzira michina, simbi nesimbi mapurojekiti ekuvaka, kuvaka ngarava, magetsi ezuva anotsigira, simbi chimiro engineering, magetsi emagetsi, zvidyarwa zvemagetsi, zvekurima nemakemikari michina, girazi keteni madziro, mota chassis, airport, boiler. kuvaka, njanji dzenzira, kuvaka dzimba, zvakafanana nemachubhu emakwere, nezvimwe.
Kupatsanurwa kwegobvu nemadziro epaipi pombi yekugadzira maitiro
Zvinoenderana nemaitiro ekugadzira, gobvu madziro sikweya pombi yakakamurwa kuita inopisa-yakakungurutswa gobvu madziro mativi pombi, inotonhora inoswededzwa gobvu madziro sikweya pombi, extruded gobvu madziro sikweya pombi uye welded sikweya pombi.
(a) Zvinoenderana nemaitiro - arc welding square chubhu, kuramba welding square chubhu (yakakwira frequency uye yakaderera frequency), gasi welding square chubhu uye choto welding square chubhu.
(b) Yakakamurwa ne weld - straight welded square pombi uye spiral welded square pombi.
Square machubhu akakamurwa kuita akajairwa kabhoni simbi sikweya machubhu uye yakaderera alloy square machubhu zvinoenderana nezvinhu. Ordinary kabhoni simbi yakakamurwa: Q195, Q215, Q235, SS400, 20 # simbi, 45 # simbi, etc; Low alloy simbi dzakakamurwa kuita Q345, 16Mn, Q390, St52-3, nezvimwe.
Square machubhu akakamurwa kuita yenyika akajairwa square machubhu, Japanese standard square chubhu, British standard square chubhu, American standard square chubhu, European standard square machubhu uye asiri-standard square chubhu zvinoenderana nemaitiro ekugadzira.
Square mapaipi akaiswa muchikamu zvichienderana nechikamu chimiro:
(1) Yakareruka chikamu square chubhu - square chubhu, gobvu madziro rectangular chubhu.
(2) Sikweya pombi ine chikamu chakaoma - ruva rakaita gobvu madziro mativi pombi, rakavhurika gobvu madziro sikweya pombi, marata gobvu madziro mativi pombi uye yakakosha-yakaumbwa gobvu madziro epaipi.
Zvinoenderana nepamusoro pekurapa, gobvu madziro sikweya pombi yakakamurwa kuita: gobvu madziro inopisa-dip galvanized square pombi, gobvu rusvingo electro galvanized square pombi, gobvu rusvingo oiled square pombi uye gobvu rusvingo pickled square pombi.
Makobvu ane madziro ane mativi echubhu anoiswa maererano nekushandiswa kwawo - sikweya machubhu ekushongedza, sikweya machubhu echishandiso chemuchina, masikweya machubhu eindasitiri yemakemikari, sikweya machubhu eindasitiri yemakemikari, masikweya machubhu echimiro chesimbi, sikweya machubhu ekuvaka ngarava, sikweya machubhu emotokari. , machubhu masikweya ematanda esimbi nemakoramu, nemachubhu masikweya ezvinangwa zvakakosha
Machubhu eskweya anokamurwa nemadziro emadziro - super gobvu madziro square machubhu, gobvu madziro square machubhu uye matete emadziro square machubhu.
Huremu hwekuverenga huremu hwehukobvu hwakakomberedzwa sikweya pombi: 4 * madziro ukobvu * (kurutivi kureba kwemadziro ukobvu) * 7.85
Kuverengera formula yehuremu hwepombi: {(perimeter ÷ 3.14) - kukora kwemadziro} * ukobvu hwemadziro * 0.02466
Iyo yakanyanya kutsanangurwa yerectangular pombi yekugadzira mutsetse we process Institute ndeye 500mm * 500mm * 19mm, inova yechipiri munyika. Iyo yakakura 26 inch square chubhu yekugadzira mutsara weNippon Steel munyika ndeye 550mm * 550mm * 22mm. Parizvino, iyo yakakura kududzira yeskweya rectangular pombi munyika dzeEurope neAmerica ndeye 400 * 400 * 12.7mm.
Mumakore achangopfuura, nekudyara kwehurumende mukuvaka kukuru, mamwe mapurojekiti makuru emanisipala uye ekuvaka munyika yose atora chimiro chesimbi. Nekuda kwemabhenefiti ekutarisika kwakanaka, kushushikana kwakadzikama uye nyore node kurapwa, hombe-saizi gobvu yakakomberedzwa square chubhu rectangular chubhu inoshandiswa zvakanyanya muairport terminal building Truss structure system uye curtain wall inotsigira sisitimu yenzvimbo dzemitambo uye Kokorodzano nenzvimbo dzekuratidzira dzakapararira. inoshandiswa senhengo dzesimbi. Nekudaro, mukushandisa kunoshanda, mapaipi emakona uye rectangular simbi anosanganawo nemamwe matambudziko anoda kugadziriswa nekukurumidza.
Kuti uderedze uremu uye uvandudze mashandiro ekuchengetedza senge kudengenyeka kwepasi uye kupikisa kupikisa, simbi yakasimba-yakanyanya kushandiswa zvakanyanya kumba nekune dzimwe nyika, uye muganhu wesimba rezvinhu wasvika 630mpa kana kutopfuura. Kusimba kwekusimba kwesimbi yepasi yeskweya uye rectangular pombi inogadzirwa nekuita inogona kusvika 630mpa, inomira yekutanga munyika zvichienderana negiredhi resimba rechigadzirwa. Iyo yakanyanya simba rezvigadzirwa zveNippon Steel yekugadzira mutsara muJapan ingori 550MPa, ine mutsauko ungangoita gumi nemashanu%.
Ukobvu hwepamusoro hweskweya uye rectangular chubhu inogadzirwa nemaitiro ndeye 19mm. Ukobvu hwepamusoro haungoratidziri muhupamhi hwakakwana, asiwo muhupamhi hwechigadzirwa. Ukobvu indekisi yakakosha yekuomerwa kwekutonhora kupeta kuumba. Iyo square chubhu inoratidzirwa neiyo kumucheto ukobvu ratio. Parizvino, kunowanzo tenda kumba nekune dzimwe nyika kuti kana mupendero ukobvu reshiyo iri pasi pegumi, chigadzirwa chine kukwirira kuumba kuoma. Kune sikweya uye rectangular pombi inogadzirwa nemaitiro, kumucheto ukobvu reshiyo yechigadzirwa chine chikamu chidiki uye yakakura madziro ukobvu inogona kusvika 7, senge 100mm * 100mm * 14mm, 120mm * 120mm * 16mm, nezvimwe.
Iyo inotonhora-yakaumbwa yakakura-saizi gobvu madziro square pombi yakagadzirwa neB490RNQ inopisa-yakakungurutswa simbi inosangana zvizere uye inodarika zvinodiwa zveyenyika standard Q345B maererano nemidziyo yemagetsi patembiricha yekamuri, kuumba kwayo nekugadzirisa zvivakwa zvakaenzana kana zvirinani pane Q345B, uye muyero wegoho unosangana nezvinodiwa zvekudengenyeka kwenyika indasitiri yekuvaka indasitiri. Panguva imwecheteyo, kuita kwayo kwepamusoro-tembiricha kuri nani zvakanyanya kupfuura Q345B yedanho rakafanana. Pa600, simba regoho reB490RNQ rinoramba riri pa310mpa, iro rakakwirira kudarika 2/3 yekushisa kwekamuri goho resimba, ukuwo simba regoho reQ345B nehupamhi hwemadziro hunopfuura 8mm mu500 process yakaderera pane 2/3. yekamuri tembiricha goho simba.
