1) cold punch cavity die
冷冲凹模
1.
The crack arrest in Cr12 cold punch cavity die with half-embedding and half-ellipse crack on inside surface using electromagnetic heating was analyzed.
对内表面含有半埋藏半椭圆裂纹的Cr12冷冲凹模进行了电磁热止裂研究。
2) silicon steel sheet cool punching concave die
硅钢片冷冲凹模
3) cold stamping female die
冷压凹模
1.
The fracture analysis result of the failure cold stamping female die shows that the little crack of the cold stamping die belongs to fatigue crack,and that at the same time the non-uniform distribution of the carbide can introduce the crack origination and the low-cycle fatigue rupture failure of die.
由冷压凹模断口形貌失效分析结果表明,凹模内壁微小裂纹属于疲劳裂纹,同时凹模材质CrWMn钢中的所存在的碳化物不均匀性诱发了裂纹的产生,导致模具在低周疲劳状态下发生断裂失效。
