High-speed precise numerical-control stamping machine mechanismstructure capable of realizing dynamic lower dead point precision compensation

The invention discloses a high-speed precise numerical-control stamping machine mechanismstructure capable of realizing dynamic lower dead point precision compensation. The high-speed precise numerical-control stamping machine mechanismstructure consists of a slider-crank mechanism, two push rods, two multi-rod mechanisms, two lower connecting rods and a stamping slider, wherein the slider-crank mechanism is arranged on a stamping machine body along the vertical direction, the vertical-movement stamping slider is arranged right belowunder the slider-crank mechanism, the two push rods, the two multi-rod mechanisms and the two lower connecting rods are respectively and symmetrically arranged at the two sides of the slider-crank mechanism, the slider-crank mechanism and the two multi-rod mechanisms are connected together by the two push rods, and the stamping slider and the two multi-rod mechanisms are connected together by the two lower connecting rods. According to the high-speed precise numerical-control stamping machine mechanismstructure capable of realizing the dynamic lower dead point precision compensation, the influence on horizontal-movement sliders, subjected to dynamic precision adjustment, caused by a stamping machining impact load is little, thereby being beneficial to the improvement of compensation precision and the prolongation of the service life of an adjustment system.
