NXZ Bearing Rail Transit Workshop has successfully completed the upgrade and renovation of an automatic phosphating line for bearing rings

Recently, the rail transit workshop successfully completed the upgrade and transformation of an automated bearing ring phosphating line, effectively improving overall production efficiency. This transformation not only solved long-standing equipment malfunctions that had plagued production, but also fully demonstrated the wisdom and commitment of employees in innovation, improvement, cost reduction, and efficiency enhancement.

Before the upgrade, the phosphating line used a traditional belt conveyor structure. During operation, the belt frequently experienced slippage, misalignment, wear, and even breakage, resulting in a high equipment failure rate. Frequent downtime for maintenance not only severely impacted the continuity of the bearing ring phosphating process and slowed down the overall production pace, but also required continuous monitoring by dedicated personnel, increasing manpower and placing employees under high labor intensity for extended periods. This conveyor belt had become a bottleneck restricting the production capacity and quality stability of this process.

Faced with this problem, the workshop did not directly apply for new equipment procurement, but instead turned its attention to the surplus conveyor belts stored in the warehouse. Adhering to the principle of "saving costs and making the most of resources," the workshop quickly organized a technical team to tackle the problem. Based on a detailed assessment, and considering the actual operational needs of the phosphating line and the conveying characteristics of the bearing rings, the team meticulously designed a feasible upgrade plan.

During implementation, the upgrade team selected still-durable surplus conveyor belt components from the warehouse to replace and reinforce the original structure. By redesigning the tensioning mechanism and optimizing the support and guiding structure, the operational stability and load-bearing capacity of the conveyor belt were significantly improved. The entire renovation process made full use of existing resources and minimized cost input.

After the renovation, the phosphating line's operation was significantly improved. Equipment failure rates were drastically reduced, the new conveyor belt operated smoothly, and previously frequent malfunctions were largely eliminated, ensuring continuous and stable production. Production efficiency was effectively improved, downtime was significantly reduced, and the bearing ring phosphating process was smoother. Employee workload was also reduced, and the stability of automated operation was enhanced. There was no longer a need for dedicated personnel for continuous monitoring and emergency handling, freeing employees from repetitive, high-intensity monitoring work, allowing them to perform higher value-added tasks, thus increasing employee satisfaction. Furthermore, the renovation made full use of scrap materials, saving on new equipment purchase costs and putting into practice the company's management philosophy of repairing and reusing old materials to reduce costs and increase efficiency.

This successful renovation of the bearing ring phosphating line conveyor belt is an effective innovation based on practical problems and utilizing existing resources. Practice has proven that through meticulous observation, rigorous design, and proactive implementation, small renovations can also solve major problems and create tangible benefits. This initiative not only improved the production efficiency of specific processes, but also fostered a positive atmosphere of innovation and continuous improvement within the workshop, accumulating valuable experience for the ongoing efforts to reduce costs, increase efficiency, and optimize equipment.
