The Design of Mechanisms for Automatic Press in Powder Metallurgy

The design process of the mechanisms for automatic press in powder mentallurgy is introduced,which is reconstructed by ordinary puncher. The coordination relation of movement of automatic press is studied. According to the techhological requirement of pressing process,the angle of one cycle operation of the crankshatt is allocated to solve the question of the coordinations of mutual noninterference for three groups of mechanisms follower movement by circulation diagram of movement. The combination mechanisms of the automatic press for powder metallurgy are designed. According to displacement corresponding realtion, the relation of master follower roatation angle of the powder transmission system is studies, and the can is also designed.
