Document Type and Number:
Japanese Patent JP5631337
Kind Code:
B2
Abstract:
There is provided a forming apparatus having a simple and compact structure in which rolls can be easily exchanged, without mounting a hydraulic actuator or the like for forming or disassembling a stack body of roll chocks and yokes on inner frames or a roll stand, for the purpose of enabling the rolls to be exchanged, by withdrawing the stack body from a forming roll stand in a direction perpendicular to a product proceeding direction. For realizing this, the inner frames are arranged in the forming roll stand so as to move up and down. Mechanical structures of convexo-concave engagement are provided on opposed faces between the respective roll chocks and yokes and the inner frames. After connection with a pressing device is released, the roll chocks and yokes are guided utilizing the moving-downward motion of the inner frames, and the stack body is formed in series so as to be withdrawn from the roll stand. The stack body is disassembled utilizing the moving-upward motion of the inner frames, and the roll chocks and yokes can be guided to the desired positions inside the stand and locked.
