摘要： 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are guided utilizing the moving-downward motion of the inner frames, and the stack body is formed in series so as to be withdrawn from the roll stand.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.
摘要翻译： 提供了一种成形装置，其具有简单且紧凑的结构，其中可以容易地更换辊子，而不需要在内框架或辊子支架上安装用于形成或拆卸辊轴承座和轭架的堆叠体的液压致动器等， 通过沿着与产品行进方向垂直的方向从成形辊架撤回堆叠体，从而能够更换辊的目的。 为了实现这一点，内框架被布置在成形辊架中以便上下移动。 在相应的辊轴承座和轭架与内框架之间的相对面上设置凸凹接合的机械结构。 在释放与加压装置的连接之后，利用内框架的向下运动来引导辊轴承座和轭架，并且堆叠体被串联形成以便从轧机机架中抽出。 利用内部框架的向上运动来拆卸堆叠体，并且可以将辊轴承座和轭架引导至支架内的期望位置并锁定。
