摘要

METHOD OF BENDING FOR DOUBLE forming machine for bending SECTIONS METAL FOR PRODUCING ELBOW A LEFT AND RIGHT OF 90 (degrees) OR MORE UNDERSTANDING THE MACHINE forming TWO POSTS CURVADO (10A, 10B) between which there is a clamping element (17 ), each comprising POSTS CURVADO (10A, 10B) a bending assembly (12) with a rotating (13) A disc that includes a CONTRASTADOR FINS (15) and a pin BENDING (15), IN WHICH , in order to perform two consecutive CODOS in opposite directions to each other in the same piece ROUND (16), the following steps are included: - ELBOW PERFORMS FIRST ROUND IN PART (16); SOAR CONTRASTADOR ELEMENT (15) AND ALSO RISES PART ROUND (16) to a level at least higher than the top (14A) of the pin BENDING; - DISC ROTATING (13) TURNS TO CARRY CURVADO pin (14) on the opposite side PIECE ROUND (16) WITH RESPECT TO THE OCCUPIED PRIMERCODO POSITION TO BE CARRIED OUT; - CONTRASTADOR repositions ELEMENT WING (15); - THE ROUND PIECE (16) ADVANCES TO ELBOW NEXT FOR THE POSITION; - PERFORMING AN ELBOW IN THE OPPOSITE DIRECTION TO ELBOW PERFORMED PREVIOUSLY. MACHINE forming DOUBLE TO CARRY OUT THE METHOD MENTIONED, where each element CONTRASTADOR FINS (15) is associated with an actuator (18) for lifting ABOVE THE PLANE BENDING IN A LEVEL correlated with Pin Height CURVADO (14) AND THE LOWER LEVEL IN THIS PART ROUND (16) to be formed.
