How can Manhart (Guangdong) CNC Machine Tool Co., Ltd. avoid punching defects caused by improper mold clearance?

To avoid punching defects caused by improper mold clearance, the following aspects can be taken into consideration:
1. Reasonably determine the punching gap: The size of the punching gap has a decisive impact on the quality of the workpiece and the lifespan of the mold. If the gap is too large, it will make the cross-section of the punched part not bright and rough, the size is too large, and the convex die is prone to wear; If the gap is too small, it will increase the punching force, make the convex and concave molds prone to wear, and in severe cases, they may even get stuck. Therefore, it is very important to reasonably determine the punching clearance. Generally speaking, the gap value can be calculated and selected based on factors such as material thickness, strength, and hardness.
2. Regular inspection and maintenance of molds: The accuracy and stability of molds also have a significant impact on the cutting effect. Therefore, it is necessary to regularly inspect and maintain the mold, repair worn and damaged components in a timely manner, and ensure the accuracy and stability of the mold.
3. Control punching force and stamping speed: The magnitude of punching force and stamping speed can also affect the cutting effect. If the punching force is too large or the stamping speed is too fast, it will generate excessive heat and stress during the punching process, leading to defects such as cracks and deformation in the punched parts. Therefore, it is necessary to control the punching force and stamping speed reasonably based on factors such as material properties and thickness.
4. Optimize punching process: In addition to the above measures, the punching process can also be optimized to avoid punching defects caused by improper mold gaps. For example, using advanced punching processes such as multi-station progressive molds and continuous molds can improve punching efficiency and accuracy, and reduce problems caused by improper mold clearances.
In short, to avoid punching defects caused by improper mold gaps, multiple factors need to be comprehensively considered, starting from mold design, manufacturing, use, and maintenance, and taking effective measures to ensure the quality and stability of punching.
