I. Importance of Tribological Properties of Stamping Dies
Tribology studies the friction, wear, and lubrication behavior between interfaces. During stamping, the interaction between the die and the sheet metal is complex and variable, and changes in the coefficient of friction directly affect the metal flow state, stress distribution, and surface quality. Reasonable control of tribological properties can achieve the following goals:

- Improve forming accuracy: Reduce frictional resistance, promote uniform sheet flow, reduce wrinkles and cracks, and ensure product dimensional accuracy.

- Extend die life: Optimize frictional conditions to reduce die wear, improve die durability and stability, and reduce replacement and maintenance frequency.

- Energy saving and environmental protection: Reduce frictional losses to lower energy consumption, adopt advanced lubrication technologies and materials, and achieve green manufacturing.

- Promote process innovation: Through tribological control, develop new stamping processes such as high-strength steel stamping and precision forming, and promote technological upgrading in the industry.

II. Current Research Status of Tribological Properties of Stamping Dies
Currently, the academic and industrial communities have reached a consensus: the frictional behavior of stamping dies is comprehensively affected by material properties, surface condition, lubrication conditions, and process parameters. Related research mainly focuses on the following four aspects:

1. Material Surface Treatment Technology: Through processes such as surface spraying, nitriding, and laser strengthening, the surface roughness and hardness of molds are adjusted, significantly improving their tribological properties and achieving the requirements of low friction and high wear resistance.

2. Lubricants and Lubrication Technology: Advanced products such as solid lubricants, nano-lubricants, and environmentally friendly water-based lubricants improve lubrication effects while reducing environmental impact; intelligent lubrication systems enable precise control of lubrication volume, further improving lubrication efficiency.

3. Friction Models and Simulation: Applying numerical techniques such as finite element analysis (FEA) and multi-scale simulation, accurate friction models are constructed to guide mold design and process optimization, reduce trial-and-error costs, and promote the implementation of digital manufacturing.

4. Real-time Monitoring and Intelligent Control: Combining sensor technology, the friction state and wear degree of molds are monitored in real time, enabling intelligent prediction and maintenance, extending equipment lifespan, and ensuring production continuity and stability.
