Abstract

SE PRESENTA UNA MAQUINA DE SOLDAR POR ARCO ACCIONADA POR UN MOTOR ADAPTADA PARA CONVERTIR LA SALIDA DE CA DE UN GENERADOR PARA SOLDAR EN UN SALIDA DE CC PARA QUE PUEDA LLEVAR A CABO UN CONTROL DE CONMUTACION MEDIANTE LA UTILIZACION DE UN CIRCUITO DE CONMUTACION PARA DETECTAR UNA SALIDA DEL CIRCUITO DE CONMUTACION Y CONTROLAR SU PERIODO DE ACTIVACI(ALFA)N/DESACTIVACI(ALFA)N SEGUN EL CONTENIDO DETECTADO PARA CONTROLAR UNA CORRIENTE DE SOLDADURA. ESTA MAQUINA DE SOLDAR ACCIONADA POR UN MOTOR CONSTA ADEMAS DE UN CIRCUITO GENERADOR DE UNA SEÑAL DE REFERENCIA PARA GENERAR UNA SEÑAL DE REFERENCIA TAL QUE CUANDO LA TENSION DETECTADA A TRAVES DE LOS TERMINALES DE SOLDADURA SEA SUPERIOR A UN PRIMER VALOR PREDETERMINADO, TENGA UN PRIMER VALOR DE REFERENCIA, CUANDO LA TENSION DETECTADA SEA INFERIOR A UN SEGUNDO VALOR DE REFERENCIA MAYOR QUE EL PRIMER VALOR DE REFERENCIA Y CUANDO LA TENSION DETECTADA SE ENCUENTRE ENTRE EL PRIMER Y SEGUNDO VALORES PREDETERMINADOS, TENGA UN VALOR DE REFERENCIA CON UNA CARACTERISTICA DE CAIDA QUE CONECTA DE FORMA CONTINUA EL PRIMER Y SEGUNDO VALORES DE REFERENCIA PARA ASI COMPARAR UNA SEÑAL DETECTADA EN EL TERMINAL DE SOLDADURA CON LA SEÑAL DE REFERENCIA DEL CIRCUITO GENERADOR DE SEÑALES DE REFERENCIA PARA CONTROLAR EL CIRCUITO DE CONMUTACION. ADEMAS, ESTA INVENCION SE PUEDE UTILIZAR CON MAQUINA DE SOLDAR POR ARCO ACCIONADA POR UN MOTOR QUE TENGA UNA FUNCION LIMITADORA DE LA CARGA. EN ESTE CASO SE UTILIZA AVR EN UN BUCLE DE REGULACION POR REACCION PARA LA TENSION DEL GENERADOR. LA CONFIGURACION DEL CIRCUITO INCLUYE UN CIRCUITO CARACTERISTICO DE F/V Y UN CIRCUITO SUPRESOR DE LA SALIDA PARA COMPARAR UNA TENSION DETECTADA DEL GENERADOR DE SOLDADURA CON UNA TENSION DE REFERENCIA PREDETERMINADA PARA SUMINISTRAR, CUANDO LA TENSION DETECTADA SEA INFERIOR A LA TENSION DE REFERENCIA, UNA SEÑAL PARA SUPRIMIR UNA SALIDA DE SOLDADURA A UN CIRCUITO DE CONTROL DE CORRIENTE CONSTANTE PARA CONTROLAR LA CORRIENTE DE SOLDADURA DE MODO QUE SEA IGUAL A UN VALOR FIJO.
