Its operating principles are: Ituse electric motors level triangle belt transmission and secondary gear transmission toslowdown. Then, itdrives the crank rotate, The crank connected toslide block and moving blades inthe slippery way make the back and forth straight line sport ,makes the moving blades and the fixed blade shear and cut steel. According tothe working environment choice the type ofelectric motors, using horizontal installation, protection ofthe electrical, squirrel-cage three-phase asynchronous motor. Option three slowdown, first level belt slowdown, followed bythe secondary gear deceleration . First level with the introduction ofautomated, because ithas abuffer, absorb shock and operate smoothly, small noise, and can protect the over loading. Then introduce asecondary gear deceleration slowdown, because gear transmission can beused totransmit arbitrary space between the two axis movement and momentum, and the scope ofpower, transmission efficient transmission accurately, long using life, such assafe and reliable character. Power output byelectric motors through slow down transmission system toimport power tothe executive body. Asthe system make rotation movement, The steel cutting machine needs the back and forth straight line sport ,in order toachieve this transformation, wecan use cslider-crank ear and
