Udonga olushinyeneyo lwempahla yombhobho wentsimbi
Owona mahluko mkhulu phakathi kombhobho wentsimbi eludongeni olungqindilili kunye nombhobho wentsimbi obhityileyo wodonga ulele kubunzima bodonga lombhobho wentsimbi. Ngokubanzi, imibhobho yentsimbi eludongeni olucekethekileyo ibuchwephesha obutsalwa ngokubanda, ngelixa imibhobho yentsimbi eludongeni eshinyeneyo ibuchwephesha obujikelezileyo. Ukuba yahlulwe ngeyunithi yokulinganisa, kuthathwa ngokubanzi ukuba ubukhulu bodonga / idayamitha yombhobho elingana ne-0.05 yindawo yamanzi phakathi kombhobho wentsimbi yodonga olungqingqwa kunye nombhobho wentsimbi obhityileyo, umbhobho wentsimbi obhityileyo onobunzima bodonga / ububanzi bombhobho ngaphantsi kwe-0.05 kunye nombhobho wentsimbi ongqindilili onobubanzi obungaphezulu kwe-0.05. Ngokubhekiselele kwisicelo, umbhobho wensimbi obhityileyo usetyenziswa kakhulu kumbhobho. Umbhobho wentsimbi ongqindilili wodonga usetyenziswa ikakhulu kwindawo engenanto. Isetyenziselwa ukunyanzeliswa koxinzelelo kunye nemibhobho ebalulekileyo.
Izinto ezisetyenziswa ngokuqhelekileyo e-China zezi: 10 #, 20 #, 45 #, 42CrMo, 36crmo, 40Cr, 20Cr, 15CrMo, 12Cr1MoV, Q235A, Q235B, 0Cr13, 1Cr17, 001cr5, Q4, Q4, Q4, 1, 001cr5, Q4, Q4, Q4, Q4, Q4, Q4, 19, Q4, Q4, 1, 001cr5, Q4, Q4, Q4, Q4, Q4, 1, 19 Cr1, Q4, 1, Q4, 1, 1, 19, 1, 1, Q4, Q4, Q4, 1, 1, 1, 1, 1, 1. L290, X42, X46, X70, X80.
Xa udibanisa imibhobho yentsimbi eludongeni olungqindilili, coca kuqala i-oyile, ipeyinti, amanzi, irusi, njl. Ezityebileyo ziya kuvulwa zibe zikhulu kwaye ezibhityileyo ziya kuvulwa zincinci (i-angle grinder), kwaye ke isithuba phakathi kweemveliso, ngokuqhelekileyo amaxesha angama-1-1.5 ububanzi bentonga ye-welding okanye i-welding wire. Ukuba i-groove ivulwe ngengozi enkulu, inokugcinwa incinci. I-spot welding iya kwenziwa ubuncinane ngamanqaku amathathu. Ngokuqhelekileyo, kulula ukusebenza kwiingongoma ezine. Xa i-welding, kufuneka ifakwe isiqingatha. Indawo yokuqala kufuneka ibe malunga ne-1 cm ngaphezu kwendawo engezantsi, ukwenzela ukuba idibeneyo ingenziwa ukusuka kwelinye icala. Ukuba udonga lombhobho wensimbi lunzima, kufuneka lubekwe, ubuncinane ubuncinane ezimbini. Uluhlu lwesibini lunokudityaniswa kuphela emva kokuba uluhlu lokuqala ludityaniswe kwisangqa esipheleleyo.
Ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka okunqamlezayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukhuphelo → ukuhluba umbhobho → ukulinganisa (okanye ukunciphisa) → ukupholisa → ukulungisa → uvavanyo lwe-hydrostatic (okanye ubhaqo lwesiphene) → ukumakisha
Xa ubukhulu bodonga lombhobho wensimbi bungekho ngaphezu kwe-12.5mm, ukuqiniswa kwe-weld akukho ngaphezu kwe-3.0mm; Xa ubukhulu bodonga lombhobho wensimbi bukhulu kune-12.5mm, ukuqiniswa kwe-weld akuyi kuba mkhulu kune-3.5mm.
Umbhobho wensimbi kunye nobukhulu bangaphandle obuqhelekileyo obungekho ngaphezu kwe-168.3mm iya kuba ngqo okanye ngokwesalathisi sokugoba esivunyelwene ngumthengisi kunye nomthengi.
Kwimibhobho yensimbi ene-nominal yangaphandle ububanzi ngaphezu kwe-168.3mm, i-curvature ayiyi kuba ngaphezu kwe-0.2% yobude obupheleleyo bombhobho wensimbi.
Kuba umbhobho wentsimbi kunye nobukhulu bodonga obukhulu kune-4mm ekupheleni kombhobho, isiphelo sombhobho sinokucutshungulwa nge-groove ye-30 ° + 5 ° 0 °, ingcambu ye-1.6mm ± 0.8mm, kunye ne-slope ekupheleni kombhobho ingaphantsi okanye ilingana no 5mm.
