Abstract
A general type press system with variable-speed slider-crank mechanism driven by a servomotor which can be used for various types of press work by providing various corresponding input speed trajectories. The press includes a frame, a linkage-mechanism with a crank as its input and a slider as its output, and a servomotor. The servomotor is used for driving the crank of the linkage-mechanism. The output motion of the press, i.e., the ram's motion, is accomplished by the slider of the mechanism. The speed of the servomotor is controlled by a micro-computer or a personal computer equipped with a digital signal processor (DSP). This computer supports a number of speed functions for different types of press work to obtain optimal processing results. Because the existing traditional linkage press can also be upgraded to a multi-purpose press, the disclosed press is an innovative design with the advantages of flexibility and practicability.
