QA35Y-16 hydraulic combined punching & shearing machine design

A new QA35Y-16 hydraulic combined punching & shearing machine has designed. The shearing mechanism has been analyzed and established mathematical model between size and motion parameters. The machine can be realized the parametric design by to solve nonlinear equations. It´s simpler with the same power and structure, the shearing width increase of 37.5%. QA35Y-16 is controlled by the MCU, can realize single, continuous, micro punching and shearing operation, and has the function of automatic counting and pre-setting. It adopts a transmission lever and a single cylinder, working stroke has large pressure, its speed is proper and return speed is high. Comparing with other machines, it´s obviously improved the ability to shearing with different shapes of steel such as square, round, and angled.
