Kwinkqubo ye-welding, ngenxa yokuba ukutshintshwa kokuchasana kuya kukhokelela ekutshintsheni kwe-welding yangoku, i-welding current ifuna ukulungiswa ngexesha. Okwangoku, iindlela ezisetyenziswa ngokuqhelekileyo ziquka indlela yokuchasana okuguquguqukayo kunye nendlela yokulawula ngoku rhoqo, njl., injongo yayo kukugcina i-welding yangoku ngokuqhubekayo ngokusebenzisa amanyathelo okulawula. Ngenxa yokuba ukuchasana okuguquguqukayo kunzima ukulinganisa, umsebenzi wokulawula kunzima ukuphumeza.
Ke ngoko, uXiaobian wamkela indlela yolawulo lwangoku ukuxoxa, kwaye kuqala ahlalutye izizathu ezikhokelela ekuchanekeni kolawulo lwe-welding ephantsi. Ulawulo lwangoku lwe-intermediate frequency spot welding machine, usebenzisa ummiselo we-thyristor conduction Angle ukulawula i-welding yangoku, i-China isebenzisa i-50Hz ngokutshintshana ngoku, ixesha li-20ms, umjikelo ngamnye unamaza amabini, isiqingatha ngasinye se-10ms, ukuba kukuba, ukulawulwa kwe-Angle yokuqhuba i-thyristor inokuhlengahlengiswa kuphela kwi-10ms. Ngokubhekiselele kulawulo lwedijithali, ixesha lokubetha li-10ms.
Le 10ms yingxaki: ixesha lokubetha lide kakhulu. Ekubeni ukuchasana kwento edibeneyo kuya kutshintsha ngokunyuka kweqondo lokushisa, ixesha le-10ms lanele ukuvelisa inani elikhulu lokutshintsha. I-Angle conduction ibalwa ngexesha lokuqala le-10ms ayisafanelekanga kurhulumente emva kokutshintsha kokumelana, ngoko ke i-welding yangoku iya kuvelisa impazamo enkulu. Emva kokuba ulawulo lwe-loop evaliweyo lwamkelwe, i-Angle conduction ye-beat elandelayo inokulungelelaniswa ngokwe-welding current ebuyiselwe yimpendulo, kodwa ingxaki efanayo iya kwenzeka kwi-beat elandelayo, kwaye imveliso yangoku yomlawuli iya kuhlala ihleli. Itenxa kakhulu kwixabiso elinikiweyo.
Kolu hlalutyo lungentla, kunokubonwa ukuba ixesha elide lokubetha sesona sizathu sikhokelela kwimpazamo enkulu ye-welding yangoku. Kwinkqubo ye-welding, ukuba utshintsho oluchasayo lunokuqikelelwa kwangaphambili, kwaye izinto ezichaphazelayo zithathelwa ingqalelo xa kubalwa i-angle, i-angle enengqiqo ngakumbi inokufumaneka, ukwenzela ukuba i-welding current isondele kwi-angle. ixabiso. Ngokusekelwe kule nto, ulawulo lwe-feedforward longezwa kwisiseko solawulo oluqhelekileyo, kwaye i-algorithm yokulawula i-feedforward ngokuyinhloko ukuqikelela utshintsho lwangoku olubangelwa utshintsho oluchasayo. Ngaloo ndlela injongo yolawulo oluchanekileyo lwe-welding current iyafezekiswa.
