What are the common faults of metal stamping parts?

The metal stamping parts are formed in the progressive die by punching the remaining material around the stamping parts to form the shape of the stamping parts. The main reason for the turning and distortion of the punching parts is the influence of the punching force. When punching, due to the existence of the punching gap, the material is stretched on one side of the die (the material is warped upwards) and compressed on the side of the punch. When using the unloading plate, the unloading plate is used to compress the material to prevent the material on the die side from warping upwards. At this time, the force of the material changes accordingly. As the discharge plate increases its pressing force, the material on the punch side is stretched (compression force tends to decrease), while the material on the concave die surface is compressed (tension force tends to decrease). The overturning of the metal stamping parts is caused by the stretching of the material on the die surface. Therefore, when punching, pressing and compacting the material is the key to prevent the punching from turning over and twisting. Causes and countermeasures of turning over and twisting of stamping parts during bending. It is caused by the burrs of the punching parts produced during blanking. Need to study the cutting edge, and pay attention to check whether the blanking gap is reasonable. During the blanking process, the turning, distortion and deformation of the blanking parts have occurred, resulting in poor forming after bending, which needs to be solved from the blanking and unloading station. It is caused by the instability of stamping parts during bending. Mainly for U-shaped and V-shaped bending. To deal with this problem, the guiding position of the stamping part before bending, the guide position during the bending process, and the pressing of the material during the bending process to prevent the stamping part from slipping during bending are the key points to solve the problem. The precision of hardware-stamping products reaches 0.01MM, the daily output is 3 million punching times, and the mold can be produced in 4 days. Strictly abide by the confidentiality agreement.
