A New Mechanical Press with Controllable Mechanism (Hybrid Driven Mechanical Press)

Summary

A family of new mechanical presses is invented. This type of presess is programmable (including its stroke, speed and acceleration) and energy-efficient (it uses a flywheel to ease the peak energy). Mechanically, it is a 2 degree-of-freedom punching mechanism driven by two different motors (a common motor and a servomotor). This mechanism provides an infinite number of strok travels desirable for varieties of stamping operations (such as blanking, drawing, sheet forging, progressive, transfer, and so on). The mechanical dimesions are optimized for maximum performance and the two motors are selected by minimizing the energy consumption of the servor motor. The PC based control system provides easy usage and optimal control of the press.
