The cam for thorn riveting and flattening mechanism in automatic riveting machine is the key to decide the quality of electrolytic capacitors.Taking riveting machine of full-automatic riveting/winding assembling appliance

Through motion simulation for its 3D model in Inventor

it is found that the original cam motion performance is conform to the law of quadratic polynomial

the vibration and shock of riveting machine has impact on product processing quality.Based on the quintic polynomial

the improvement of this mechanism is carried out

the motion law of cam oscillating bar is changed.Experiments show that through optimization

the precision and stability of riveting machine is improved.The quality of aluminum electrolytic capacitor becomes better.
