3.1刀片间隙

The 3.1 blade clearance

上、下刀片间隙过小时，剪切断面的断裂带易被挤坏，剪切力也会增大。当间隙过大时，条料的弯曲和拉伸严重，毛刺增大，尺寸精度下降。上、下刀片间

5.剪切力的确定

一般在剪板机上的铭牌上都有明确的规定，当铭牌上没有此数据时应查阅剪板机的使用说明书。

To determine the 5 shear stress

General provisions are clear in the cutting machine on the nameplate, nameplate onthe data when no should consult the shearing machine instructions.

6.检验

6.1 操作者对每批剪切件的首件应自检，自检合格后再交给检验员检验，经检验员检验合格后方可继续生产。

6 inspection

6.1 the first piece of each batch of shear connectors should be self inspection, self inspection and then to inspector inspection, the inspector before it can continue to produce.

6.2检验员应根据剪切件的品种和数量，除进行首件检验外，还应随时进行抽检，发现问题及时解决。

6.2 the inspector should according to the variety and quantity of shear connectors, in addition to conduct first article inspection, also should carry out sampling at any time,to find and solve problems in a timely manner.
