为了保证矫正质量,矫正辊应和管棒材呈线接触。基于此,本文从啮合原理的角度推导出了斜辊矫直机矫正辊的理想型线(双曲线),并与传统的包络线法进行了比较。试验表明,新算法较包络线法精度高。 In order to ensure the quality of correction, the correction roll should be in line contact with the tube bar. Based on this, this paper deduces the ideal line (hyperbolic curve) of the correction roller of the skew-roll straightener from the aspect of meshing principle, and compares it with the traditional envelope method. Experiments show that the new algorithm is more accurate than the envelope method.
