1.Deformation

The convex and concave molds of a progressive stamping die may undergo shape deformation during use, causing geometric changes in the processed product parts, which require dimensional accuracy and shape requirements. This is mainly due to the shallow quenching hardness layer of the concave and convex molds during the heat treatment process, which causes geometric deformation during the stress process.

2.Wear and Tear

The convex and concave molds of a progressive stamping die will experience wear during prolonged and frequent friction with the processed material. Due to the large gap or burrs between the convex and concave molds, it can cause wear on the cutting edge.

3.Fracture

During use, the convex and concave molds of the Progressive stamping die may break due to the maximum punching pressure they bear during the stamping process. The reasons for the fracture may include improper heat treatment processing (such as quenching too hard or the hardness layer being too deep) or design gaps being too small.

4.Punch Fracture

Various factors such as chip jumping, waste blockage, and material jamming can all cause convex die fracture. When there is inaccurate mold guidance and wear on the guide part of the unloading insert, regular maintenance should be carried out.

5.Deformation of Machined Parts

The wear of the cutting edge can cause changes in the size of the material to be cut, and if the burrs are too large, it may cause variations in subsequent bending. It should be ground or replaced immediately.

6.Defects in Material Cutting, Punching, and Trimming

For example, excessive burrs, deformation, surface scratches, size discrepancies, missing holes, etc. The causes of these defects may include excessive or insufficient clearance between the convex and concave molds, blade wear, and poor guidance accuracy.

7.Flanging Defect

Some defects are caused by large gaps between the convex and concave molds, inaccurate positioning, and inaccurate dimensions of the dropped parts, such as uneven flanging, inconsistent flanging height, flanging burrs, and flanging cracks.
