Abstract：

A new hydraulic combined punching and shearing machine QA35Y-30 was designed.It adopted the single-cylinder and transmission lever controlled by the MCU to realize single,continuous,micro punching and shearing operation,and had the function of automatic counting and pre-setting.Shearing mechanism was optimized.So,with the same power and simplified structure,the ability of cutting steels of different shape such as square,round,angle,etc.was increased obviously.Comparing with other machines,the single cutting width was increased by 28.3%.The machine net weight was reduced by 1 t,the contour was reduced by 400mm in the length,and 14.7% reduction rate was achieved.So the QA35Y-30 is a high efficiency and low energy consumption machine with the feature of mechanical,electrical and hydraulic integration.
