Abstract
This design topic comes from the current demand for efficient and accurate cutting equipment in the industrial manufacturing field, especially in the steel plate processing industry, there is an urgent demand for the plate shear machine that can quickly and stably complete the cutting task. Considering the advantages of hydraulic drive technology in power transfer and control, as well as the application of mechanical design and manufacturing and its automation technology in improving the performance and efficiency of equipment, we chose the hydraulic drive steel plate shear machine as the research and design object. By using the combination of symmetrical transmission mode, reasonable transmission system design and efficient actuator, it aims to develop a plate shear machine with high performance and reliability to meet the requirements of modern industrial production for the continuous improvement of equipment performance.
This topic not only has practical application value, but also provides new ideas and methods for the research and practice in the field of mechanical design, manufacturing and automation. This paper introduces a design based on hydraulic drive, which combines mechanical design and manufacturing and its automation technology. The shear machine adopts symmetrical transmission mode, with 12 tons of shear force, the slider stroke is 22mm, and can complete 10 shear operations every minute. The power source in the design comes from the motor, through the first belt drive and the second gear transmission to achieve deceleration. The actuator adopts the center crank slider mechanism to effectively convert the rotational movement of the transmission system into the reciprocating linear movement of the slider to achieve efficient plate cutting function. This study not only improves the shear efficiency of shear earing, but also provides a useful reference for mechanical design in related fields.
Key words: hydraulic drive; steel plate shear; symmetrical drive; shear; slide stroke; belt drive; gear drive
