Metallic zvinhu kana simba rekunze richipfuura muganho wegoho zvinhu zvaro, zvinogadzira zvachose deformation yepurasitiki, inova ndiyo musimboti weiyokukotama kwechubhu.Kupeta chubhu, madziro ekunze nekuda kwekutambanudza kwayo uye kutetepa kwekumanikidza kwemukati nekuda kwekukora, kubva pamhedzisiro yekutambanudza nekutsikirira, uye mukukotama, iyo chubhu muchinjiko-chikamu chachinja, shanduko mune denderedzwa kupinda mukati. maitiro e ellipse.

Tube bending nzira yakakamurwa kuita marudzi maviri ekutonhora kukotama nekukotama, kutonhora kuri pakamuri tembiricha ine yakananga gokora rekupeta muchina, kukotama kwakayamwa chikamu chakakombama chechubhu chinopisa kune imwe tembiricha, uyezve mechanic (inokotama pombi muchina) kana nemaoko gokora.Cold-formed metal haiparadzi hunhu hwepakutanga, haiburitse thermal deformation.Asi magokora akaumbwa anotonhora anofanirwa kushandisa simba rakawanda, uye kudzokororwa uye kusara kushushikana kune kuwedzera kwakakosha, asi kwete kukotama radius yekumisikidza kweinotonhora-yakaumbwa diki inopinza misoro.Kuipeta hakugone kufananidzwa neinotonhora-yakaumbwa kuchinjika.

Kupeta uye kuchinjisa zvinoenderana nehurongwa, kukotama nzira inogona zvakare kukamurwa kuita "kutanga kukotama uye welding" uye "mushure mekutanga weld bend" mune maviri akasiyana maitiro ekukotama.Iyo inonzi "kutanga kukotama uye welding," inobva pane zvakasiyana-siyana zvepaipi pombi kana tsvimbo-yakafanana nezvikamu zvekugadzirisa diagram yakapiwa, yekutanga kupfugama.Uye ipapo muSAMS kana SAMS chikuva chekumisikidza chubhu flange yekubatanidza zvishongedzo, basa rewelding.Sarudza kureba kweiyo yakatwasuka pombi yekucheka machining zvikamu zvinoenderana nekudhirowa kana sampuli chubhu tsvimbo, iko kukanganisa kana uchifunga nezvegokora, kucheka kureba kwemaitiro kuisa iyo general allowance.Iyo "yekutanga weld bend" yakavakirwa pakureba kwechubhu dhirowa mutsara pombi saizi komputa inobuda kukosha kwezvikamu dhayagiramu, iyo hama angle flange screw K, flange screw angle uye chirongwa cheNC uye nhevedzano yekugadzira data, uchishandisa kwete. margin pasi pezvinhu, kutanga papuratifomu kana SAMS muchina wakamira wakatwasuka pombi flanges, welding, wozokotama basa.
