Abstract

PURPOSE: To prevent the generation of the twist and camber of a stock to be formed by setting the clearance of a roll groove face in unloading state larger than the strip plate thickness at a bearing side.
CONSTITUTION: The clearances 6-1, 6-2, 6-3, 6-4, 7-2 and 7-3 composed of the upper roll pieces 4-4, 4-2 and lower roll pieces 5-7, 5-6, 5-4 and 5-3 of an A row and B row are taken about the same as the thickness (t) of the stock to be formed. The clearances 7-1 and 7-4 composed of the upper roll pieces 4-4, 4-2 and lower roll pieces 5-8, 5-2 are set larger than the plate thickness (t) in unloading state. In this case, the clearances 7-1, 7-4 are found from the displacement at loading time of rolls 4, 5 with the forming reaction force as a center one point concentration load. The local rolling of the stocks 3-1, 3-2 to be formed is thus eliminated even if the displacement of the rolls 4, 5 at loading time be generated and the generation of twist and camber at forming time is prevented.
