摘　　要： 通过对实验室拉伸性能测试用哑铃形试样冲切装置的优化设计,包括对压板、连体裁刀、缓冲层及顶出装置等的设计,能够在实验室对哑铃形试样冲切及自动顶出。采用该装置能同时制备一组试样,提高了工作效率。连体裁刀周边的缓冲层对刀刃具有防护作用,存放安全。弹簧和顶板的配合有利于冲切后试样的自动弹出,省时省力,减少了由于取出方法不当对试样质量产生的影响,确保了试样的规范性。 Through the optimized design of the dumbbell-shaped punching device,including the design of the pressure plate,the combined cutter,the buffer layer and the ejector device,the dumbbell-shaped sample can be cut and automatically ejected in the laboratory.The device can be used to prepare a set of samples at the same time,which improves the work efficiency.The buffer layer around the cutting knife has a protective effect on the blade and keeps it safe.The combination of the spring and the top plate is beneficial to ejection of the sample after punching,,reducing the effect of the improper removal method on the sample quality and ensuring the normality of the sample.
