高性能复杂整体模锻件要求巨型模锻液压机必须具备多缸同步运行的能力,但由于锻件材质不均、形状不对称等原因,巨型模锻压机极易出现活动横梁倾斜现象。针对这一问题,本文建立了模锻液压机同步系统的数学模型,在考虑模锻压机各工况特点的基础上,对同步系统性能进行了仿真验证。通过对仿真系统的综合分析得了压机系统各参数对同步性能的影响规律,以及提高压机同步系统稳定性、控制精度、抑制最大偏转角以及缩短纠偏时间的方法。
High-performance complex overall forging pieces require giant forging hydraulic press must have the ability to synchronize multi-cylinder operation, but due to uneven forging material, asymmetric shape and other reasons, the giant forging press is prone to tilt the movable beam. To solve this problem, this paper established a mathematic model of hydraulic system for die forging press. Based on the characteristics of each working condition of die forging press, the performance of the synchronous system was verified by simulation. Through the comprehensive analysis of the simulation system, the influence law of the parameters of the press system on the synchronization performance is obtained, as well as the ways to improve the stability, control accuracy, maximum deflection angle and shorten the correction time of the press synchronization system.
