Kwimizi-mveliso yangoku,{0}}oomatshini bokuwelda bamaxesha aphakathi baye baba sisixhobo esiyimfuneko kumashishini afana neemoto, izixhobo zasekhaya, kunye nombane. Ngenxa yokusebenza kakuhle kwabo, -ukugcina amandla, kunye neempawu ezihambelana nokusingqongileyo, aba matshini bewelda basetyenziswa kakhulu kwiinkqubo ezahlukeneyo zokwenziwa kweemveliso.
Xa usebenzisa-i-inverter yamaxesha aphakathioomatshini bokuwelda amabala, uyilo kunye nemilinganiselo yamaqhuqhuva omsebenzi abalulekile njengoko achaphazela ngokuthe ngqo umgangatho we-welding kunye nokusebenza kakuhle kwemveliso. Ngokulawula ngokuchanekileyo ubungakanani kunye nokumila kwamaqhuqhuva, amandla e-welding anokuphuculwa, iziphene zincitshiswe, kwaye iindleko zemveliso ziphuculwe.
Ubungakanani bamaqhuqhuva kunye nokuTyaniswa koButyenene beMathiriyeli
Phakathi{0}}oomatshini bokuwelda amabala aqhelekileyo aneemfuno ezingqongqo zobude beqhuqhuva lomsebenzi, ngokwesiqhelo 1.2 ukuya ku-1.5 ukuphinda-phinda ubukhulu bezinto. Umzekelo, xa welding 1.5mm carbon steel sheets, enconyiweyo ukuphakama nodule phakathi 1.8mm kunye 2.2mm. Ukuba ukuphakama kwamaqhuqhuva akuhambelani nomgangatho, kunokubangela ukuhla komgangatho we-welding:
- I-Nodule ephantsi: I-nodule ephantsi iya kubangela ukuba i-current isasazeke, ikhokelela kumandla anganeleyo we-welding, enokuthi ichaphazele uzinzo kunye nokuthembeka kwexesha elide le-weld.
- I-Nodule ephezulu: Iqhuqhuva eliphezulu kakhulu linokubangela ukuxinana okugqithisileyo kwangoku, okunokubangela ukutshiza okanye ukutshisa{0}}kudlule, kuchaphazele kakubi ukuchaneka kweweld.
Olu phawu luthetha ukuba ubungakanani beqhuqhuva kufuneka buchaneke ngokuchanekileyo kubukhulu bezinto zokuqinisekisa ukusasazwa kobushushu kunye noxinzelelo ngexesha lenkqubo ye-welding.
I-Nodule Diameter kunye ne-Electrode Pressure Coordination
Kwiwelding ebonakalayo, idiameter yeqhuqhuva kufuneka ilungelelaniswe noxinzelelo lwe-electrode yomatshini wokuwelda webala eliphakathi{0}} Ngokusekwe kwidatha yokwenyani{2} yehlabathi, amaqhuqhuva amakhulu afuna uxinzelelo oluphezulu lwe-electrode ukuqinisekisa umgangatho wokuwelda.
Ngokomzekelo, xa udibanisa i-nodule enobubanzi obuyi-5mm, uxinzelelo lwe-electrode kufuneka ilawulwe phakathi kwe-70,000N kunye ne-75,000N. Olu luhlu loxinzelelo luqinisekisa uqhagamshelwano oluzinzileyo ngexesha lenkqubo ye-welding kwaye ikhusela ukusabalalisa okungalinganiyo kwangoku kunye neziphene ze-weld.
Umsebenzi wohlengahlengiso loxinzelelo lwe-electrode kwindawo ephakathi{0}}kumatshini wokuwelda amabala aphindaphindayo kwenza olu lungelelaniso phakathi koxinzelelo kunye nedayamitha yeqhuqhuva lwenzeke, ukuqinisekisa ukusasazeka kwendawo etyhidiweyo kunye nokuphucula amandla e-weld joint.
Imilo yamaqhuqhuva kunye noHlengahlengiso lweMphumo yangoku
Phakathi{0}}isiguquli sokuphindaphindaoomatshini bokuwelda amabalazixhotyiswe ngesakhono esinamandla solawulo lwangoku, ngowona mzuzu uphezulu -wesekethe yangoku ukuya kuthi ga kwi-60KA. Ke ngoko, uyilo lobume beqhuqhuva lubalulekile. Imilo yejiyometri eqhelekileyo efana nesiqingatha-esetyhula okanye i-conical nodules inceda ujoliso lwangoku kunye nokunciphisa inkcitho yamandla. Ngokwahlukileyo, amaqhuqhuva amile ngokungaqhelekanga angakhokelela ekusabalazweni okungalinganiyo kwangoku, okuchaphazela kakubi umgangatho we-welding.
Ngokulungisa imilo yamaqhuqhuva, imveliso yangoku esebenzayo inokuqinisekiswa, ukuphucula umgangatho we-welding, ukunciphisa ukusetyenziswa kwamandla kwezixhobo, kunye nokunciphisa iindleko zemveliso.
Impembelelo ye-Electrode Wear kwiMimano yeNodule
Ngokuhamba kwexesha, ii-electrode eziphakathi{0}}kumatshini wokuwelda amabala aqhelekileyo ziya kuthi kancinane ziwohloke, oko kubangele indawo yoqhagamshelwano eyandisiweyo, echaphazela uzinzo lwemilinganiselo yamaqhuqhuva.
Ukugqoka okuqhubekayo kunokukhokelela kumgangatho we-welding ongazinzanga, ngoko ke kuyimfuneko ukugaya i-electrodes ngezikhathi ezithile ukuze kugcinwe ukucoceka kwendawo kunye noqhagamshelwano.
Ukongezelela, ukusebenzisa inkqubo yokupholisa kunokunciphisa ngokufanelekileyo isantya sokunxiba i-electrode, ukwandisa ubomi benkonzo ye-electrode. Ukuhlolwa rhoqo kunye nokugcinwa kwee-electrode kubalulekile ekuqinisekiseni ukuhambelana kwe-welding kunye nokuphucula ukusebenza kakuhle kwemveliso.
Ukuqukumbela
Iimfuno zamaqhuqhuva omsebenzi aphakathi{0}}oomatshini bokuwelda indawo abaphindaphindayo abalungiswanga kodwa kufuneka bahlengahlengiswe ngokusekwe kwiipropati eziphathekayo, iiparamitha zezixhobo, kunye neemfuno zenkqubo. Ngokulawula ngokuchanekileyo ubude, ububanzi, imilo ye-nodule, kunye noxinzelelo lwe-electrode, umgangatho we-welding unokuphuculwa kakhulu ngelixa ukwandisa ubomi benkonzo yezixhobo.
Kwimisebenzi eyenziwayo, kuyacetyiswa ukuba kusetyenziswe eyonyani{0}}imisebenzi yokubeka iliso yexesha eliphakathi{1}}lomatshini we-frequency spot welding ukuze ngokuqhubekayo uphucule useto lweparameter, uqinisekisa imveliso esebenzayo nezinzileyo.
Ngaphaya koko, njengesixhobo sokuwelda esisebenzayo-esisebenzayo, -i-frequency ephakathi umatshini wokuwelda indawo ayiphuculi nje kuphela umgangatho wee-welds kodwa ikwanciphisa iindleko zemveliso kumashishini, iyenza ibe sisixhobo esiphambili ekufezekiseni ukwenziwa kobuchule.
