首先分析了辊式楔横轧机刚度好,但扇形模具加工困难,板式楔横轧机刚度差、占地面积大,但平板模具加工容易,而且两者都不宜加工较大工件.据此分析结论,提出了辊压板式复合楔横轧机的力学原理,进而提出了复合楔横轧机的设计原理和整机设计.在上下滑动压板的上方和下方分别设有上下压辊,压辊与滑动压板滚动接触,平板模具是嵌装在上下滑动压板中,而且成形过程中上下压辊的中心线与轧件的中心线始终在同一垂直面内,这既保留了辊式楔横轧机刚度好和板式楔横轧机模具加工简单的优点,又克服了板式楔横轧机刚度差和辊式楔横轧扇形模具加工复杂的缺点,而且能轧制较大工件.
First of all, the analysis of the roll cross wedge mill stiffness, but the fan-shaped mold processing difficulties, the plate wedge cross-rolling mill stiffness is poor, covers an area of ?? large, but the flat mold processing is easy, and both are not suitable for machining larger parts.According to the analysis of conclusions, The principle of the composite cross wedge rolling mill was proposed and the design principle and machine design of the composite cross wedge rolling mill were put forward.The upper and lower pressure rollers are respectively arranged above and below the upper and lower sliding pressure plate and the pressure rollers are in rolling contact with the sliding pressure plate , The flat mold is embedded in the upper and lower sliding platen, and the forming process center line of the upper and lower pressure roller and the rolling centerline always in the same vertical plane, which not only retains the roll cross wedge stiffness and wedge The advantages of simple mill processing and overcoming the shortcomings of the plate wedge cross-rolling mill stiffness and rolling cross wedge fan mold complex processing, but also rolling larger workpieces.
