Laser Shock Peening (LSP) is an advanced surface strengthening technology. By impacting the material surface with a high-energy laser beam, a high-pressure shock wave is generated, thereby forming a layer of high residual stress on the material surface. This technology has a remarkable effect on improving the fatigue resistance, wear resistance and service life of materials. In the application of electric hammers, laser shock strengthening technology can also significantly enhance their performance.
First, enhance the fatigue resistance of bearings
The bearing is a key component in the electric hammer, withstanding high loads and high-frequency impacts. Laser shock strengthening technology can significantly improve the fatigue resistance of bearings. For instance, research shows that GCr15 bearing steel that has undergone laser shock strengthening treatment has significantly enhanced surface hardness and wear resistance, enabling it to better withstand high-frequency impacts. In addition, laser shock strengthening can also form a high-density dislocation network and low-angle grain boundaries on the bearing surface, further enhancing its fatigue resistance.
Second, optimize the microstructure
Laser shock strengthening technology can optimize the microstructure of materials, thereby enhancing their mechanical properties. For example, after laser shock strengthening treatment of IN718 alloy, its densification rate increased to 99.5%, the average grain diameter decreased by 30.8%, and the microstructure had the specified strong texture. The optimization of this microstructure not only enhances the strength and wear resistance of the material, but also improves its performance at various strain rates.
Third, enhance the overall performance of the electric hammer
Through laser shock strengthening technology, the overall performance of the electric hammer has been significantly improved. For instance, laser shock strengthening can significantly enhance the service life and reliability of electric hammer bearings and reduce downtime caused by bearing failures. In addition, laser shock strengthening technology can also optimize the transmission system of the electric hammer, enhancing its transmission efficiency and stability.
Fourth, future development direction
With the continuous advancement of technology, the application of laser shock strengthening technology in electric hammers will become more extensive and in-depth. Future research directions may include:
Intelligence and automation: Through advanced sensors and control systems, the operating status of the electric hammer is monitored in real time, and the laser shock strengthening process is automatically adjusted as needed.
New materials and processes: Develop new reinforcing materials and processes to further enhance the performance and service life of the electric hammer.
The application of laser shock strengthening technology in electric hammers has significantly improved the fatigue resistance of bearings, optimized the microstructure, and enhanced the overall performance of electric hammers. Through laser shock strengthening technology, the electric hammer can maintain stable performance under high-load and high-frequency shock conditions, reducing wear and failure rates. In the future, with the development of intelligent and automated technologies, laser shock strengthening technology will bring more possibilities for the performance improvement of electric hammers.
