Design, Modeling, And Simulation Of Tin Earphone Device Control System In Copper Electric-anode Automatic Product Line

Hydraulic control and transmission technology has become an important technology of industrial automatism, and it is the key component of mechanic-electronic. The electro-hydraulic control is one of the most vivid branches of this technology. Proportional unit do not need a high requirement of the clearness of media but rather cheaper, and the static and dynamic responding supplied can meet the using requirements in most industrial fields, and in some fields is no worse than servo valves. The Proportional control technology has a broad prospect in industrial application. So, the research to this proportional closed loop control system has an important theory value and application meaning.This paper takes tin earphone device, which is the main equipment in copper electric-anode automatic product line, as researched object, by referencing some foreign advanced technologies, designs and testifies the result through theoretical analyses, and find some rules. Based on the analysis of each composites of Tin earphone device, it analysis first the key part Milling tool's geometrical parameters, structure and manufacturing abilities. And an experiment is also taken. With the electro-hydraulic proportional directional restricting flowing valve, pressure-reducing valve, DC line speed measuring sensor etc, the electro-hydraulic proportional closed loop speed control system is designed, and the speed of the longitude feeding equipments of Tin earphone can be controlled. This paper analyzes the composting usage of several hydraulic valves thoroughly;construct with emphasis the mathematic model of electro-hydraulic proportional closed loop speed control system with pressure difference compensation. Using the computer engineering software, it analyzes the system and its components' static and dynamic performance, and designs a reasonable corrector, so that the performance of the system designed can fit the application producing requirements better.The practice shows that developed copper electric-anode automatic product line has obtained the anticipated object, which has created huge economic benefits.
