【摘要】 本课题主要是对MW1050自动烫金模切机中模切烫金部件的肘杆机构进行了分析研究。具体内容和创新归纳如下： 1) 采用极坐标矢量法对肘杆机构进行了运动特性分析，得到活动平台的位移、速度和加速度等参数。研究表明肘杆机构动态特性对模切精度的影响较小，但所产生的动压力对模切压力影响较大。 2) 应用达朗贝尔原理对肘杆机构进行了刚性动力学分析，评价模切压力的大小及其影响因素，为企业设计和使用模切机提供参考依据，也为模切压力的测试奠定了基础。 3) 建立了一套肘杆机构活动平台加速度测试系统，对MW1050自动烫印模切机空载状态和加压工作状态进行了实测。根据测得的数据，得到了肘杆机构活动平台在两种情况下的实际运动规律，并验证了理论分析的正确性。 4) 对模切机模切加载过程进行分析，采用数学方法拟合了一条加载过程曲线，确定了肘杆机构可承受的最大模切压力值。 通过本课题的研究，为该模切机的改进提供了可靠的理论依据，并为进一步开发该设备的运行状态监测系统奠定了基础。更多还原

【Abstract】 In this article, elbow-bar framework of the Die-Cutting system of MW1050 Automatic Blocking Die-Cutter produced by Shanghai Yahua Printing Machine Ltd. Co. was analyzed. The main contents and innovations are as follows:1. The movement characteristic analysis of elbow-bar framework is dealt with to gain displacement, velocity and acceleration of moving bedplate by adopting polar coordinates vector method. The research result indicates that dynamic characteristic of elbow-bar framework less influences the die-cutting precision, but the moving press brought by it has more influence.2. Rigidity movement analysis of elbow-bar framework is disposed to evaluate die-cutting press and its affect by using d’Alembert principle, whose result offers the design and use of enterprise reference, and establish a base for the test of die-cutting press.3. A set of acceleration test system of elbow-bar framework is founded for the material test of MW1050 automatic blocking die-cutter while it is load-off or not. On the base of the tested data, actual movement rule of moving bedplate on the condition of two instances and validate the correctness of theory analysis.4. After the analysis of loading process, a loading curve is simulated by math method,which fixes on the most press value that can be endured by elbow-bar framework.The thesis not only provide necessary analysis and credible theoretic proof for improve velocity of Automatic Blocking Die-Cutter, but also lay a foundation for further development of running state inspecting system of the device.更多还原
