摘　　要：在传统的管材斜辊矫直原理的基础上 ,通过数模分析 ,建立了一套以辊子的布置方式、辊形函数和调节影响系数三项基本参量表示的数学模型 ,该数学模型具有广泛意义 ,同时适合多环节矫直机和单环节矫直机 ,开发了十一辊高精度管材矫直机 ,其矫直精度由传统的 0 .1%～0 .35%提高到 0 .0 0 8%～ 0 .0 0 2 5% ,圆度也提高了 30 %～ 50 %。实践证明采用多环节组合辊列不等辊距布置能有效提高矫直精度。Based on the principle of traditional pipe inclined roller straighten, the math model composing of three basic parameters is established, that is the roller position arrangement, roller shape function and adjusting coefficient. This model is very meaning. It suit to more tache and single tache straighten machine. The straighten precision of the developed 11 roller high precision pipe straighten machine is improved from the traditional 0.1% -0.35% to 0.008%-0.0025%, the roundness is also improved 30%-50%. It approved that adopting the more tahce combined roller line and different distance arrangement can improve the straightening precision effectively.
