1·The way that two kinds of different potentiometer feeding back the blade gap value in adjusting mechanism of CNC shear have been introduced.

介绍了数控剪板机刀片间隙自动调整机构中两种不同电位器反馈刀片间隙值的方式。

2·This article analyzed the problem about the reasonable choice of horizontal blade gap while double_sides rotary cutting shear and rotary cutting length shear to cut steel plates.

分析了滚切式双边剪和定尺剪剪切钢板时剪刃水平间隙（以下简称剪刃间隙）的合理选择问题。

3·The gap of shear force among finite element simulation, the tested value and calculated value, the results confirmed the correctness of finite element simulation.

有限元模拟得到的剪切力与实测值和经验公式计算值差距很小，证实了有限元模拟结果的正确性。

4·And the impact of the parameters on shear force was analyzed, which includes overlap, side gap, cutting speeds and so on.

并分析了重叠量、侧向间隙、剪切速度等工艺参数对剪切力的影响。

5·Results from the experiment show that the load bearing ability of the single-lap joint decreases as the length of the gap increase but the actual shear strength is increased in same time.

结果表明，随着间隙长度的增加，接头的承载能力趋于减小，但接头的实际剪切强度却持续上升；当间隙长度继续增加时，接头的实际强度趋于下降。

6·Research on the formula for blade gap regulating of slitting double-sided shear and length shear;

滚切式双边剪是宝钢厚板厂切边的主要设备，其剪刃间隙与边部质量的好坏关系密切。

7·The concave block the existence of occlusion chain, so shear force is provided by ash from the gap and the chain, and the specimen cracking load and ultimate load are higher than ordinary masonry.
