Its operating principles are: It use electric motors level triangle belt transmission and secondary gear transmission to slowdown. Then, it drives the crank rotate, The crank connected to slide block and moving blades in the slippery way make the back and forth straight line sport, makes the moving blades and the fixed blade shear and cut steel. According to the working environment choice the type of electric motors, using horizontal installation, protection of the electrical, squirrel-cage three-phase asynchronous motor. Option three slowdown,first level belt slowdown, followed by the secondary gear deceleration. First level with the introduction of automated, because it has a buffer, absorb shock and operate smoothly, small noise, and can protect the over loading. Then introduce a secondary gear deceleration slowdown, because gear transmission can be used to transmit arbitrary space between the two axis movement and momentum, and the scope of power, transmission efficient transmission accurately, long using life, such as safe and reliable character. Power output by electric motors through slow down transmission system to import power to the executive body. As the system make rotation movement, The steel cutting machine needs the back and forth straight line sport ,in order to achieve this transformation, we can use c slider-crank institutions or gear and rack. I decided to consider realistic conditions using slider-crank as the executing machinery.Keywords cutting architectural reinforcing steel dar gear slider-crank
