铝护套的质量对保证电缆的安全运行有着重要的作用,这也是本文写作的动因。
铝护套的生产工艺比较多,大致上可以分为:保护焊连续生产工艺、液压铝棒式连续生产工艺以及铝杆式连续挤压生产工艺。
由于铝护套生产工艺属于连续生产的项目,需要从铝杆放线、电缆放线、前后牵引以及挤压成型、冷却轧纹、收线成盘等几大部分。
面面俱到的进行项目介绍有一定难度,所以本文重点就铝护套成型的定径模及相关工艺进行介绍。
本文依托某大型电缆企业的双铝杆式铝护套挤压机的调试和产品试制,主要分析了铝护套的生产工艺、模具设计。
本文通过对各项工艺参数和模具设计的深入分析,运用模具设计理论及材料的合理选择,行成完整的研究方案。
本文的研究结论和成果对国内铝护套生产,在理论和实践两方面有借鉴意义。

Logistics centre a large-scale real estate projects requires system design and planning, all-embracing project introduced is difficulty, so the article focuses on the design of the overall idea of the centre as well as internal and external planning and design .This article relies on the Yuxi modern integrated logistics centre construction projects, mainly introduces the construction of a logistics centre design and comprehensive evaluation. Based on in-depth analysis of the construction of YUXI logistics parks necessity and feasibility, use Logistics Park and Planning theories, method to formate Park Planning and Construction program, Finally, comprehensively Evaluate Construction of logistics parks programConclusions of this study and the results of the logistics centre, both in theory and practice is worth learning for In the western region of China.Keywords:H Logistics Park,Construction scheme,Comprehensive Evaluation重庆大学硕士学位论文 1 绪论目录中文摘要 ································································错误!未定义书签。
