金属材料的拉伸、冲击等试验中,在试样端头打钢字模时,由于试样端面小,不易夹持,会出现将拉伸试样打弯,冲击试样打飞的情况。若试样较多,会使这一问题更棘手。在实践中,我们自制了一个试样打钢字模用夹具,很好地解决了这一难题。 Metal materials such as tensile, impact and other tests, the sample when playing steel-type die, the sample end is small, not easy to hold, there will be tensile specimens bent, the impact of sample flying. If more samples will make this problem more difficult. In practice, we made a self-made steel plate with a fixture, a good solution to this problem.
