Abstract

PURPOSE: To regulate the forming work for the metallic material always to uniform treating condition, and to perform a wide range of forming work, by tuning up the distortion of the moving apron to the distortion of the long size stationary apron.
CONSTITUTION: The amount of distortion of the moving apron 5, depending on the forming condition for the metallic material to be formed, is regulated so as to tune up to the distortion of the stationary apron 11. Next, the main lever 43 is turned round keeping the relation of the positional upper limits of two contact levers 53, 65; and the positional upper limits of levers 53, 65, against the contact pieces 55, 83, are set. Under this condition, the metallic material (sheet) is interposed between the upper die 15 and the lower die 9, and then, the forming work is performed. Hereupon, the main cylinder 17 installed under the moving apron 5 and the subcylinders 19a, 19b, installed at both sides of the main cylinder 17, are driven to extend by the specified pressure difference through the oil pressure control circuit. The positional upper limits of cylinders 17, 19a, 19b, are previously set by the positioning device 23 in order to stop the extending motion of each cylinder at its positional uppor limit, and the distortion of the press machine is straightened.
