| 目的 介绍一种新型拉伸机冲杆行星齿轮式驱动机构。 方法 首先，对易拉罐成型拉伸动作进行概述；然后，简要分析了传统拉伸机冲杆驱动机构的结构组成及工作原理；其次，详尽分析新型拉伸机冲杆行星齿轮式驱动机构的结构组成及工作原理，并进行了受力分析；最后，对传统与新型拉伸机驱动机构进行比较分析，得出了新型拉伸机驱动机构的优异特点。 结果 传统的驱动机构实质上是曲柄滑块机构，冲杆会受到垂直水平方向变化的分力，从而影响冲杆的工作性能；新型的驱动机构实质上是行星齿轮式直线运动机构，冲杆不受到垂直水平方向的分力，不会影响冲杆的工作性能。 结论 新型拉伸机冲杆行星齿轮式直线运动驱动机构的特点是振动小，稳定性能好，能达到设计要求。 |

| Abstract: |
| To introduce a new kind of bodymaker punch planetary gear driving mechanism, this paper firstly summarized the cans forming and stretching movements; secondly, briefly analyzed the structures and working principles of the traditional bodymaker driving mechanism; thirdly, detailedly analyzed the structures and working principles of the new bodymaker punch planetary gear driving mechanism; finally, compared the traditional with the new driving mechanism bodymaker and obtained the excellent features of the new bodymaker driving mechanism. The traditional driving mechanism was essentially the slider-crank mechanism. The punch of the slider-crank mechanism was subject to a system of forces from horizontal and vertical direction, which badly affected the punch's performance. The new driving mechanism was essentially the planetary gear type linear motion mechanism. The punch would not change by vertical and horizontal direction component, without degrading performance of the punch. The features of the new bodymaker punch planetary gear driving mechanism are small vibration, good stability, and conformance with the design requirements. |
