Abstract

      The design of symmetric transmission shears, shear-to 10 tons, the itinerary for the slider 22 mm per 30 minutes shear. Powered by the motor through a belt drive and a slowdown Gear. Design of the implementation agencies right mind crank slider, This will shears transmission rotation slider into the reciprocating linear motion, the realization of the right of sheet metal shear. Crank slider is simple in structure, easy processing, easy to maintain and repair, economic and practical advantages in machinery, equipment widely used. The design, right through the plane crank slider mathematical modeling, Turbor C programming, input slider crank agencies that such remarks parameters and the parameters of the whole movement of the simulation process.
