摘要
下死点精度是伺服压力机的关键性能指标之一。主要影响因素有压力机整体刚度、加工装配精度、工作环境以及冲压模式等。本文在分析国内外研究现状基础上,提出了一种压力机下死点精度实时检测和自动调节控制方法。通过NC装置、伺服调模电机、滑块位移光栅尺以及温度控制装置,实现对压力机下死点精度的自动调节,有效保证了压力机下死点工作精度和精度稳定性。
A real-time detection and automatic adjustment control method of BDC precision has been put forward to the press in the text on the basis of domestic& foreign research status analysis. The automatic adjustment of the BDC precision for press has been achieved by means of NC device, servo motor, sliding displacement grating scale and temperature control device. The working precision and precision stability of BDC in press have been ensured effectively.
