How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. regularly inspect and adjust mold clearances?

Regular inspection and adjustment of mold clearances are important measures to ensure the quality of punching and the lifespan of the mold. Here are some suggested steps and methods:
1. Determine the inspection cycle: Determine the appropriate inspection cycle based on factors such as the frequency of mold use, material properties, and punching accuracy. It is usually recommended to conduct a weekly or monthly inspection, but the specific cycle should be adjusted according to the actual situation.
2. Prepare tools: Prepare necessary tools and measuring equipment, such as vernier calipers, feeler gauges, micrometers, etc., to accurately measure gap values.
3. Disassembling the mold: Remove the mold from the punching machine, clean it thoroughly for clearance inspection.
4. Check the gap: Use tools such as vernier calipers and feeler gauges to measure the gap value between the convex and concave molds. Measure at multiple locations to ensure the uniformity of gap values. If the gap value is found to be too large or too small, it needs to be adjusted in a timely manner.
5. Adjust the gap: Select the appropriate adjustment method based on the size of the gap value. For example, methods such as gasket method, electroplating method, and paper cutting method can be used to adjust the gap. The specific method should be selected based on the structure and characteristics of the mold.
6. Reassembly and trial punching: After adjusting the gap, reassemble the mold and perform a trial punching. Observe the punching effect, and if any problems are found, continue to adjust the gap until the best effect is achieved.
7. Record data: After each inspection and adjustment of the gap, relevant data should be recorded, such as gap value, adjustment method, trial punching effect, etc. These data can provide reference for subsequent maintenance and debugging.
In summary, regular inspection and adjustment of mold clearances are key steps to ensure the quality of punching and the lifespan of the mold. By having a reasonable inspection cycle, preparing necessary tools, selecting appropriate adjustment methods, and recording relevant data, it is possible to effectively avoid punching defects caused by improper mold clearances.
