Design Calculation of Linkage-structured Centering Roll Steadier
-
摘要: 定心辊装置是无缝钢管穿制生产线上的一个重要装置,它在管坯穿孔过程中抱紧顶杆和毛管,可以起到提高穿孔机顶杆的刚度以及防止顶杆和毛管跑偏而造成毛管内孔偏心、质量下降的作用。介绍了一种连杆机构定心辊装置的新型设计计算方法,即采用作图法和Inventor三维软件草图方法,使所设计的定心辊装置在开口度为Φ100~500 mm情况下的定心精度达到0.05 mm以上。Abstract: As one of the key mill units of the seamless steel pipe rolling plant,the centering roll steadier clamps the plug bar-shell piece during the piercing process so as to enhance the rigidity of the piercer plug and bar prevent any deviation of the plug bar-shell piece from the normal rolling line,which may consequentially lead to internal bore eccentricity of the shell,and thus lessen the product quality. A calculation method for designing a new type of leakage centering roll steadier is elaborated here in the paper,i.e.,using both the construction technique and the Inventor 3-D sketch software to make the centering accuracy of the said centering roll steadier as designed up to 0.03 mm when the opening rangs is of Φ100~500 mm.
