1·Tools for forge machine, die insert, extrusion mould for Cu alloy, hot shearing knives.

平锻机上的凸、凹模，铜合金挤压模，镶块，高温工作下的热剪切刀。

2·The die for the blanking under the radial clamp of nuts for 1C engine is designed based on The effect of radial stress on the shearing method for bars and the fracture shape.

根据轴向应力对棒料剪断方式及其断口形状的影响，设计了对螺帽锻造所用热轧棒料能进行精密剪切下料的新型结构的径向支持下料模具。

3·Shearing force, which is necessary in device inspection, increases with the die dimension, and challenges the reliability of back metallization process greatly.

剪切力是器件考核的基本项目，随管芯面积的增大而增大，这就对背面金属化可靠性提出了较高的要求。
