Abstract

METODO DE FABRICAR UNA UNIDAD DE PISTON DE CILINDRO. SEGUN UN EJEMPLO ILUSTRADO DE LA INVENCION, UN AMORTIGUADOR DE VIBRACIONES DE TUBO DOBLE SE CIERRA CURVANDO RADIALMENTE UNA PORCION DE EXTREMO SUPERIOR DEL CILINDRO DE CURVAR FORMANDO UNA PESTAÑA DIRIGIDA RADIALMENTE HACIA DENTRO. DICHA CURVATURA SE EFECTUA MEDIANTE UN RODILLO DE CURVAR. DICHO RODILLO DE CURVAR SE BASCULA ALREDEDOR DE UN EJE DE BASCULAMIENTO SUSTANCIALMENTE TANGENCIAL A LA SUPERFICIE DEL RODILLO DE CURVAR Y SUSTANCIALMENTE TANGENCIAL AL CILINDRO ADYACENTE A SU PORCION EL EXTREMO SUPERIOR.METHOD OF MANUFACTURING A CYLINDER PISTON UNIT. ACCORDING TO AN ILLUSTRATED EXAMPLE OF THE INVENTION, A DOUBLE TUBE VIBRATION DAMPER CLOSES BY RADIALLY BENDING A TOP END PORTION OF THE CYLINDER TO BEND FORMING A RADIALLY DIRECTED INNER TAB. SUCH BENDING IS CARRIED OUT THROUGH A BENDING ROLLER. SUCH A BENDING ROLLER IS TILTED AROUND A SUBSTANTIALLY TANGENTIAL TILTING AXIS TO THE SURFACE OF THE CURVING ROLLER AND SUBSTANTIALLY TANGENTIAL TO THE CYLINDER ADJACENT TO ITS PORTION THE UPPER END.
