本文主要阐述了旋转框架式矫直机的结构特点,其中涉及矫直机的结构设计的说明、工作原理等。由于挤压或连铸的铜管坯在冷却时会发生弯曲,当管坯进入轧制工序时,往往造成轧机的芯棒难以顺利地穿过管坯。因此,必须在挤压与轧制或铸造与轧制工序之间配置一台矫直设备,通过矫直提高管坯的直线度,确保在轧制时芯棒能顺利地穿过管坯内孔。常用的旋转框架式矫直机具有矫直精度高、管坯不旋转等特点,当管坯在旋转框架中交叉布置的矫直辊所形成的孔型中间通过 This article mainly expounds the structural characteristics of the rotary frame type straightening machine, which involves the description of the structural design of the straightening machine, working principle and so on. As the extrusion or continuous casting of copper tube cooling occurs when bending, when the tube into the rolling process, often resulting in the rolling mill mandrel is difficult to smoothly through the tube. Therefore, the extrusion and rolling or casting and rolling process must be configured between a straightening equipment, straightening to improve the straightness of the tube to ensure that the mandrel during rolling can successfully pass through the tube bore . Commonly used rotary frame straightening machine with high precision straightening, the tube does not rotate and so on, when the tube in the rotating frame cross-shaped straightening roller formed by the middle pass
