Factors Affecting The Service Life Of Cold Stamping Dies

3. Wear


The cold stamping die has a long time frequent friction between the convex and concave molds and the material to be processed, resulting in wear. Since the convex and concave molds rub against each other for a long time between the materials to be processed, large-scale blanking of the machined parts for a long time, the burrs of the punched parts are too large (the gap is too large), and the convex and concave gaps are too small, etc. An important reason for the wear of the convex and concave die edges. For example, the convex and concave die edges become dull, the corners become gardens, and the like.


4. Bruises


The cold stamping die has a convex and concave die gap adjustment assembly unevenly, and the adjacent edges of the convex and concave die bite each other, causing the convex and concave die edges to be bruised. For example, when the mold is assembled, the position of the convex and concave molds is offset, and the gap is not uniform. When the mold without the guide is installed, the gap adjustment of the convex and concave molds is not suitable, and the convex and concave molds are bitten and damaged.
