Title The Slider-crank Mechanism Design of Open-cycle Crank Press

Abstract Crank pressure machine is a forging machine that changes the rotation of motor into the reciprocating motion of the slider ,so that the feedstock can be molded. The crank press movement is steady and reliable, and it is widely used in crafts such as ramming, extrusion, drop forging and powder metallurgy. This article discusses the definition, crank press composition and work principle, and the classification of the press. According to the given parameters, the overall design programme is given. The components of the slider-crank mechanism are including following, such as the crankshaft, connecting rod, slider, sliding bearings and overload, closed height adjustment devices so on. The size specifications of the various parts are determined by calculating and checking. Finally, three-dimensional modeling of the crank pressure machine is given to by using the Solid works.
