Abstract
1,192,679. Curving. VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE A.G. 16 Dec., 1968 [17 May, 1968], No. 59713/68. Heading B3E. Apparatus for bending an edge portion of sheet metal to be used in the manufacture of tubes or boiler shells comprising two pairs of bending rolls 6, 7; 8, 9 movable along the edge of the sheet metal 1 to be curved and arranged one behind the other in the direction of travel is characterized in that at least one bending roll of each pair consists of two roll elements which are axially spaced apart by a variable distance, the bending roll 6, 8 disposed on the convex side of the curved portion of the sheet metal supporting the edge of the sheet metal only at two spaced-apart points 10, 11, the counterbending roll 7, 9 applying pressure to the edge of the sheet metal between these points, the bending rolls being relatively adjustable to vary their centre spacing. The metal sheet is clamped to a table 4 by hold-down members 3. The bending rolls are rotatably mounted on a carriage 5 movable on wheels along the table 4. Each lower roll consists of roll elements 6a, 6b, 8a, 8b axially adjustable by spacer discs. The counter-bending roll 7 consists of two bead-shaped roll elements 7a, 7b spaced apart by a disc 12 which apply pressure between the spaced points 10, 11 on the elements 6a, 6b of the lower roll 6. The upper counter-bending roll 9 comprises only one bead-shaped element 9a although a second could be provided. The roll pair 8, 9 curve the outer edge of the sheet metal. The upper rolls are adjustable axially and vertically for varying the centre spacing between the rolls and their axes may be inclined relative to the lower rolls. A sensing device 13 and roller feelers (not shown) indicate the curvature imparted to the sheet metal and automatically adjust the bending rolls if desired.
