在100kN材料试验机上做剪切试验,切断的试样常被剪切头挤压在装置里面,靠手锤和铁棒的敲击才能取出,这样易使剪切装置损坏,为不使剪切装置损坏,提高试验效率,我们自制了剪切装置拉勾图1。 1 原理两拉勾底部插入材料试验机工作台的燕尾槽中,其拉勾上部分别插入剪切装置底部的方形通孔中,靠 In the 100kN material testing machine to do the shear test, cut the sample is often squeezed inside the device by the shear head, by hand hammer and iron bar percussion to remove, so easy to shear device damage, in order not to shear device Damage, improve test efficiency, we made a self-made shear device pull hook Figure 1. 1 Principle Two pull the bottom of the hook into the material testing machine bench dovetail slot, the upper part of the hook were inserted into the shear at the bottom of the square through-hole, by
