Nsalu zokhala ndi zowonjezera

Pakalipano, nsalu zokometsera zimagwiritsidwa ntchito kwambiri pa zovala za amayi. Ali ndi mawonekedwe okongola, amachotsedwa bwino, ali ndi mphamvu zowonjezera komanso kutsutsana ndi dzuwa. Malingana ndi zomwe zanenedweratu, gawo la nsalu zomwe zili ndi zitsulo zamakono zidzapitiriza kukula. Komabe, kugwiritsa ntchito zipangizo zatsopano zogwirira ntchito zamagetsi kumayenderana ndi mavuto angapo. Mukameta zitsulo mofulumira, singano ya kushona makina imatentha mpaka 300-400 ° C. Popeza nsalu zokongoletsera zimakhala ndi masamba 250 ° C, pamene zimagwirizana ndi singano yamoto, zitsulo zimasungunuka, zomwe zimachititsa kuti phokoso likhale losasunthika ndipo limapangitsa kuuma ndi kuphulika kwa msoko. Chotsatira chake, liwiro la kupyola likucheperachepera, ubwino wa mankhwala omalizawo umachepa. Kuwombera zipangizo kumafuna kugwiritsa ntchito ulusi wopangira mankhwala omwewo ngati chinthucho, mwinamwake makwinya adzawonekera pa kusoka kapena kutsuka kapena kutsuka.

Pali mfundo ziwiri zowonjezera - discrete ndi mosalekeza.

Mfundo yoyamba: mgwirizano uwu wa zigawo zing'onozing'ono ziwiri pansi pa osindikiza. Kukula kwa msoko kumatsimikiziridwa ndi miyeso ya ntchito yogwirira ntchito.

Mfundo yachiwiri: ndi njira yopitilira monga kusoka. Yambani ndi m'mphepete mwa msoko ndi sequentially weld kumbali ina. Mukamagwira ntchito ndi zazikulu zazikulu, mdulidwewo umakhala pa tebulo, ndipo makina opangira zowonjezera amayendayenda. Pamene mukugwira ntchito ndi zovala zamakono - zovala zonse. Wojambula zovala amakhala pambuyo pa makina opangira zowonjezera ndipo amatsogolera mankhwalawo pogwiritsa ntchito makinawo. Ntchitoyi ikufanana ndi ntchito pa makina osakaniza. Pamene chowotcha ndi moto wamoto, "kuyanika" kuli pakati pa zigawo ziwiri zazitsulo. Njira yaikulu ya njira imeneyi ndi kutenthetsa kwa kutentha kwa moto. Mukakwera kutentha ndi mpweya wotentha, pamakhala phokoso pakati pa zigawo, zomwe mpweya wotentha umaperekedwa panthawi yovuta. Pamene kutsekemera ndi kutentha, kutsegula molunjika kwa zigawo ziwiri kumasiyana, ndi kusindikiza feletti welds mothandizidwa ndi matepi apadera. M'lingaliro lenileni, kutsegula tepi ndi ndondomeko yomatira. Pachifukwa ichi, chotsatira cha tepi yosindikizidwa chimapangidwa ndi pulasitiki motsogoleredwa ndi mpweya wotentha, ndipo tepiyo imagwiritsidwa ntchito pamsana. Ndi akupanga kuwotchera njira, zakuthupi Kutentha kumachitika chifukwa zamphamvu mphamvu. Tisaiwale kuti kutentha kwapakati kumadutsa m'kati mwazitali. Mu njira zina zowonjezera kutentha, kutentha kumachitika mwachindunji pa malo ozungulira (kuchokera mkati). Ultrasound ili ndi ubwino waukulu poyerekeza ndi njira zina zowonjezeretsa, chifukwa mu njirayi, palibe mpweya kapena mphete imalepheretsa. Koma ngakhale kwa akupanga kuwotchera pali malire a makulidwe a zakuthupi. Pa makulidwe akuluakulu, chigawo chapansi chimayaka kunja kusanayang'ane mkati mwake.

Kugwiritsiridwa ntchito kwa matekinoloje monga gluing ndi kuwotcherera kuli ndi ubwino wambiri pa njira yachikhalidwe yopangira zovala. Mbali yowonjezera zowonjezera ndi mphamvu zawo zonse. Pogwiritsa ntchito zigawo zake zamagetsi, maselo a weld ali ofanana ndi magawo a zipangizo zomwe zikugwiritsidwa ntchito. Zomwe zimagwirira ntchito zimagonjetsedwa ndi mazira a ultraviolet, monga nsalu yokha. Kuwonongedwa kwa msoko, chifukwa cha kuswa kwa ulusi pansi pa mphamvu ya kuwala ndi kuwala kwa dzuwa, ndizosatheka. Mphamvu ya msokoyi imagawidwa mofanana mpaka kutalika, ndipo sichigwiritsidwa ntchito mofanana monga mu fillet welds. Pa msoko wopangidwa ndi makina osokera ulusi amawonekera. Mtundu wa mthunzi uwu ukhoza kuyesedwa optically. Kuwombera msoko nthawi zambiri kumakhala mkati, ndipo si kosavuta kuunika kuchokera kunja. Chitsimikizo chapamwamba chimaperekedwa nthawi zambiri pogwiritsira ntchito weld weld ndikupitirizabe kukhala ndi phindu lokhazikika pomwe mutapeza mawonekedwe abwino.
