The soft collection chute in the finishing and collection area of the large bar production line at Lingyuan Iron and Steel is a core equipment in the bar packing and collection process. However, the original structure was affected by the frequent impact loads during the bar conveying process, resulting in frequent failures of the chain and the support bearing seats of the rotating sprockets. This not only directly led to production interruptions, but also significantly increased the maintenance difficulty and labor-hour costs due to the limited working space for chain restoration and the cumbersome disassembly and assembly procedures, seriously restricting the maintenance efficiency and the continuous operation ability of the entire production line. To address this production bottleneck, targeted improvement and optimization of the soft collection chute structure were implemented for the soft collection chute, including optimizing the force transmission path, enhancing the structural strength of key components, and conducting adaptive structural design. These measures fundamentally eliminated the problems of chain breakage, bearing seat damage and narrow operation space. After the improvement, the integrated operational stability of the equipment was improved by more than fivefold, while maintenance efficiency was enhanced by 80.0% to 83.3%. This was expected to generate annual direct economic benefits amounting to over 1 million yuan. It not only reduced the consumption of spare parts and maintenance costs, but also decreased the unplanned downtime, achieving a dual improvement in production efficiency and economic benefits.
