What causes the incomplete separation of precision stamping parts? 'Hardware'

What causes the incomplete separation of the trimming of precision stamping parts? The reasons are as follows: 1. The clearance of precision stamping parts is not suitable. Excessive clearance is also one of the reasons for incomplete separation of waste, or large burrs. The size of the blanking depends on the size of the die, and the gap is taken on the punch; the size of the punching depends on the size of the punch, and the gap is taken on the die. If the die is chipped or damaged, repair welding is usually performed, and then the die is processed by CNC, as a single reference, and the punch is developed. 2. The closing height of precision stamping parts is not high. This problem usually occurs during the debugging stage. Due to the unstable state of the mold, multiple debugging is required. After mass production, the parameters can be set in the press part. Generally easy to appear in the corner. 3. The height of the scrap knife for precision stamping parts is not enough, and the scrap knife is too low, resulting in poor contact between the upper and lower knife edges when trimming. The scrap knife can be repaired or the height of the installation seat of the scrap knife can be increased. The above is about the reasons that lead to the incomplete separation of precision stamping parts. I hope it will help you.
