Metal stamping die design, punch rupture easily to know the reason

Metal stamping parts in the mold design, punch rupture easily, in addition to the material of the punch and the design of itself, what are the main causes of the fracture, and everyone together to explore the young writer today? 1, metal stamping mold punch rupture in the process of production, its hardness is too high, the most obvious reason is probably punch punch material selection is not correct, we can replace the punch material, adjust the heat treatment of hardness to solve this problem; 2, mold located in installation lead to material is not correct, cause the punch cutting single side, because of its uneven stress fracture, we can adjust the position or by feeding device to solve this problem; 3, punch without fixed, jumped up and down, lead to fracture when production, we can reattach the punch, when installing the mold must pay attention to this; 4, metal stamping punch cutting edge is not sharp, increase the pressure between the products, need to grind edge; 5, material does not conform to the requirements, cause Angle is bad, lead to dimensional deviation, we can change the material or to adjust the clearance; Authors and everybody together discuss today is easier to analysis the reasons of the late we analysis the deeper reason together. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
