Abstract
The automatization of manufacturing cell or the makeup of flexible automatic production lines in the process of extrusion production is an efficient way to carry out the production in highspeed, high efficiency and high quality. It is one of the most important directions of modern extrusion technology. As special and specific extrusion equipment, it cost high and a small number have been using manual loading. Furthermore, their work efficiency is very slow in our country because its feeding and blanking depend on manual operation, which are difficult and dangerous. These traditional operation ways restrict the utilization ratio of large extrusion machines for heads seriously and have a side effect on the competitive power of domestic enterprises in international markets.
The work of my paper is as follows: to study the large-scale horizontal extrusion production process and analyze the large horizontal extrusion hosts work and structural features and the requirements for loading and unloading work to determine the loading and unloading of auxiliary works, designed auxiliary automatic loading and unloading system solutions. I determine the loading and unloading of auxiliary works and designed automatic loading and unloading system solutions auxiliaries. Starting from the system program, according to a modular design approach, calculation and analysis the mechanical gripper, rotating parts, loading and unloading devices supporting beams, as well as dynamic components of the cylinder design. Research on dynamic components used in pneumatic systems. Analysis of mechanical gripper crawl, horizontal movement and rotation angle of the rotating mechanism, developed the principle of pneumatic systems and check the strength of the key components .conclude the paper work and the problems of research and prospects of future development prospects of the loading and unloading device in summary and outlook section.
