||A toggle cutting mechanisms driven by cylindrical cam is presented, which is used in automatic die-cutting machine. First of all, to synthesize the follower motion curves of cylindrical cam, based on the rigid body transformation, the cam profiles and the properties of the cam mechanisms can be determined. In addition, the toggle cutting mechanisms is driven by the follower of cylindrical cam. Based on the vector operation, the motion of links and pins are analyzed. That is kinematics analysis of toggle cutting mechanisms.|
Since the main function of this mechanism is to provide working cutting force, from analyzing the driving force of toggle mechanism and each bearing reaction forces, based on to the cutting force from cutting action, the transmission forces between cylindrical cam and its follower is calculated and the power required by this mechanism is determined.
Furthermore, refer to the load of cardboard conveyor, through applying the rational B-splines to tune time sequence of the toggle cutting mechanisms and using different design parameters, such as the radius of the cylindrical cam, initial angle of follower and arm of follower, the power required of this mechanism is reducing and the high working speed and load toggle cutting mechanisms are investigated.
