Abstract
This article introduced Steel bar stacker Overall design theory and entire piles up the process in detail, and introduced the design of Turnover mechanism emphasis. In this paper, there has mainly included the entire design of the axis, the gear, hydraulic cylinder of turnover mechanism, and in that there were also including bearing's selection and shaft coupling's selection and examination.
This profiled bar automate profiled bar stow machine has good capability, movement is agility, operating is simple; the frequency of trouble is small, maintenance is simple, and could meet the need of teaching and learning
