为应对目前市场上长轴加工仍然以锻造和楔横单扎为主的加工方式的缺点，基于遗传算法优化，建立了多楔耦合关系，通过多楔控制，使多楔之间的转速、力矩、压力等因素形成协同关系，满足加工精度需要。通过遗传算法优化多楔内楔入段、外楔入段、多楔展宽段、内楔精整段以及外楔精整段五个阶段的控制，避免建立复杂模型从而提高了效率节约了成本。试验结果表明，楔横轧多楔同步技术克服了锻造和楔横单扎加工方式的不足，能够很好地解决长轴加工精度控制和成本问题。%Multi-wedge synchronous cross -wedge rolling is a precise technology for processing long axial parts , can well control the machining accuracy and reduce processing cost .Based on the optimization of the genetic al-gorithm, it establishes a multi-wedge coupling relationship to realize multi -wedge control .These collaborative relationships include the speed , torque , pressure and other factors of the multi wedges for the processing preci-sion requirements .It presents the genetic algorithm to optimize the control of the following five stages: multi-wedge inner wedge part , outer wedge part , multi-wedge widening part , inner wedge finishing part and outer wedge finishing part in order to avoid the establishment of complex models and reduce cost .
