1 材料分析

　　　Q表示的是该种材料的屈服极限，而数字235是指这种材料的屈服点值，在235MPa左右，而且屈服值的大小会随着材料厚度大小的变化而变化，呈负相关的关系。由于该材料的含碳量一般小于0.70%，相对而言，各方面的性能能够互补，具有良好的塑性（），综合性能表现不错，因此得到广泛应用。

　　　Q235的冲压性能良好，即使对于冲压要求比较高的零件，也能够满足生产的需要；通过综合分析，该工件具有十分良好的冲压工艺性。

2 零件结构

　　　该零件结构形状简单，无悬臂，可由落料和冲孔两道工序冲压而成。零件中有3个孔，冲孔的时候要注意孔和孔之间不能干涉。根据实际要求，该冲裁件能够进行实际的冲裁生产。

3 尺寸精度

　　　由于零件图所示尺寸没有尺寸公差，所以需要进行查阅相关图表得到。
