Q12Y20×4000B型剪切机用剪刀片脆裂原因分析

Analysis of reason of forfex slice Crack of the Q12Y20×4000 type cutter

示波冲击试验等试验手段,综合分析了9SiCr制剪刀片脆裂的原因,并指出现行剪刀片的刃口形状和它所剪切的钢板不适合采用9SiCr材料。如果必须采用,应在热处理工艺的设计上有所改进。此外,还要在被剪切钢板的材质和厚度上加以限制。

This paper applies instruct wave impact test ways, synthetically analyses reason of foffex slice crack in 9SiCr, and presents forfex slice knife edge and cutting steel plate are unsuitable with 9SiCr materialo In case this material must be used, it should improve on design in heat treatmento Moreover,material and thickness should be restricted.
