钢板剪切工艺规程

剪切工艺流程

Shenring process procedure 钢板剪切工艺规程（以下简称规程）适用于（数显）剪切机及通用剪切机斜刃剪切低碳钢板。

Steel plate shear process planning (hereinafter referred to as the rules) is suitable for the (digital) and general shearing machine shearing machine shearing of low carbon steel.

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

隙的推荐数据见表1。

Last, the lower blade clearance is too small, easily crushed fracture section of shearband, shear stress increases. When the gap is too large, the strip bending and stretching serious burr size precision, increase, decrease. The recommended dataunder the blade gap, see table 1.

表1剪切刀片间隙

3.2刀片的直线度

The 3.2 blade straightness

刀片的直线度一般规定为0.03mm。

Straightness general blade is 0.03mm.

3.3后定位及标尺

3.3 after the location and scale

根据产品图样规定尺寸要求，调整后定位及左（或右）标尺并紧固。当剪切材料较厚、尺寸比较大的板料时，为保证尺寸准确，可同时采用前后定位。

According to the drawings required size requirements, after adjustment for positioningand left (or right) scale and fastening. When cutting thick material, dimensions of material of relatively large, in order to ensure the accurate size, can also adopt thepositioning.

3.4试剪

3.4 shear test

机器调整好后，试剪1～2块料，检查试品的长宽，直线度，垂直度，毛刺高度等，若误差不符合要求，应继续调整。

Adjust the machine, try to cut 1 ~ 2 block, check the sample length and width,straightness, vertical, burr height, if the error does not meet the requirements, shouldcontinue to adjust

3.质量要求

3 quality requirements

4.1 材料平面度

4.1 material flatness

钢板平面应不大于表2的规定，当钢板平面度超过表2规定时需用钢板校平机校平后再进行剪切。

The provisions of steel plate should be less than 2, when the plate flatness specified in Table 2 with the steel plate leveling machine leveling and shearing.
