Stamping dies are important tools for metal forming and are widely used in the automotive, electronics, aerospace and other industries. Their manufacturing accuracy and life directly affect product quality and production efficiency. Traditional mold processing methods rely on manual operation, with long production cycles and difficult to ensure accuracy. CNC (computer numerical control) machine tools play an important role in stamping die manufacturing with their high precision, high efficiency and automation advantages.
1. CNC precision machining improves mold manufacturing accuracy
Key components such as the cavity, core and punch of the stamping die require extremely high machining accuracy to ensure the consistency and quality of the stamping parts. CNC machine tools can control the processing dimensions at the micron level and ensure the matching degree of each part of the mold through high-precision milling, drilling and grinding processes. For example, the stamping die of the automobile cover requires high finish. The CNC machine tool combines high-speed milling and fine grinding technology to reduce the subsequent polishing process and improve the surface quality.
2. Five-axis CNC machining optimizes complex mold structures
The design of modern stamping molds is becoming more and more complex, involving a variety of curved surfaces, deep cavities and bevel structures, and traditional three-axis machine tools are difficult to complete efficient processing. Five-axis CNC machine tools can cut from multiple angles to achieve one-time clamping processing of complex shapes, reducing tool change and adjustment time. For example, the cavity structure of the stamping mold of the metal shell of a mobile phone is complex, and the five-axis CNC machine tool can accurately control the tool angle to improve processing efficiency and accuracy.
3. Hard material processing capabilities improve mold life
Stamping molds usually use high-hardness materials, such as Cr12MoV, SKD11, etc., to improve wear resistance and service life. However, high-hardness materials are difficult to process, and traditional turning and milling processes are prone to tool loss and surface defects. CNC machine tools use high-speed cutting, hard milling and other technologies to efficiently process high-hardness mold materials. For example, using CNC hard milling to process punches and dies can reduce the discharge machining (EDM) link and increase the service life of the mold.
4. CNC automation improves production efficiency
The combination of CNC machine tools and automation systems can greatly improve the manufacturing efficiency of stamping dies. For example, the CNC machining center is equipped with an automatic tool change system (ATC), which can realize continuous operation of rough machining, semi-finishing and finishing, reducing downtime for tool change. In addition, combined with CAD/CAM software, CNC machine tools can directly read mold design data, realize rapid programming and processing, and accelerate the mold development cycle.
5. Online detection ensures mold quality
CNC machine tools are equipped with online measurement systems, which can detect mold dimensions during processing, automatically adjust errors, and ensure processing accuracy. For example, the cavity depth and surface profile requirements of large automobile stamping dies are strict. CNC machine tools can use non-contact measurement systems to monitor processing quality in real time and reduce rework costs.
Conclusion
The application of CNC machine tools makes stamping die manufacturing more accurate, efficient, and automated, shortens the mold production cycle, and increases the service life of the mold. With the development of intelligent manufacturing, CNC technology will play a greater role in the field of stamping die manufacturing, and promote the metal forming industry to move towards efficiency, precision, and intelligence.
