| 英文摘要: |
| The work aims to resolve problems present in double-J hook forming machine, such as quality instability of hook shape, low level of automation and design defects of equipment structure. Production technical process was planned in overall based on thorough research on production technology and equipment structure. Optimal design of the equipment structure was carried out using parametric 3D design software, and performance of the new equipment was analyzed by means of trial-manufacture, debugging and trial-production. The production technology was optimized to achieve full automatic production from raw materials to the hook, and production efficiency was increased by 50% or more. Wedge drive mechanism was applied to realize fast bending and forming and it could work stably and reliably. Structural design defects of the original equipment were solved. The new equipment could adapt to serial production of different double-J hooks by taking advantage of its high flexibility. The optimization of production process flow and equipment structure meets design requirements in a favorable manner, and can improve product quality and production efficiency significantly. |
