A DEVICE FOR AND A METHOD OF CORRECTING WITHOUT FLAME HEATING TRANSVERSE DISTORTION OF PANELS CAUSED DURING FORMATION OF THE SAME BY WELDING MACHINES FOR HIGH PRESSURE BOILERS

摘要

The present invention discloses a device and a method for correcting transverse distortion of Panels caused during the formation of the same by welding machines. The device comprises of two rectangular boxes (3), one placed above the panel (1) and the other below the Panel (1). The boxes (3) are coupled to two side plates (4) placed on two sides of Panel. A screw jack (5) placed over a steel bed (6) is disposed over the Panel (1) with another steel pad (7) placed on the top of screw jack (5). The handle (8) of screw jack (5) is rotated to screw up the said jack (5) against the top rectangular box (3) to provide load downwards on the distortion area of the Panel (1) to correct the distortion of the Panel (1) when the panel (1) is being placed over a plurality of stands (2).
