摘要
为实现楔横轧机轧辊的可拆卸,以便于模具更换和加热,对楔横轧机轧辊端进行设计,通过引入液压系统,实现了轧辊在工作过程中固定,在更换模具时的拆卸等工作。首先,为进一步了解轧辊工作时的受力大小,通过仿真分析得到了模具工作时的轴向载荷,以此为基础设计了以液压缸为主的液压锁紧回路,在液压缸不工作时,不因泄漏、轴向冲击等因素改变轧辊和楔横轧半轴的相对位置,保证了楔横轧工作时的稳定性。其次,为了使液压系统在冲击载荷下保持稳定,设计了以液压缸和双液控单向阀为主的液压系统,并根据其在工作载荷下的工作状态进行了优化分析。最后,利用楔横轧机样机对该液压系统进行了实验测试,验证了该系统优化方案的可行性,提升了系统的稳定性和可靠性,节省了模具更换时间,加快了企业的生产效率。
In order to realize the roller detachability for the cross wedge rolling mill and facilitate the die replacement and heating,the roller end of the cross wedge rolling mill was designed,and the roller was fixed during operation and disassembled during die replacement which was realized by introducing a hydraulic system.Firstly,in order to further get the magnitude of force during the operation of rollers,the axial load of the die during operation was obtained by simulation analysis,and based on this,a hydraulic locking circuit composed of hydraulic cylinders was designed.When the hydraulic cylinder was not working,the relative position between roller and cross wedge roll-ing half shaft was not changed due to factors such as leakage and axial impact,ensuring the stability during the cross wedge rolling opera-tion.Secondly,in order to maintain the stability of the hydraulic system under the impact load,the hydraulic system mainly composed of hydraulic cylinders and dual hydraulic control check valve was designed,and optimization analysis was conducted based on its working state under working load.Finally,the hydraulic system was tested by the cross wedge rolling mill prototype,which verified the feasibility of the system optimization scheme,improved the reliability and stability of the system,saved the time on die replacement,and accelera-ting the production efficiency of the enterprise.
