The idle power source is provided with inertial energy storage device; a r, auspicious source 'eight The utility model provides a power source capable of providing variable speed rotation; a differential transmission can be connected to the fixed speed power source and the Wei power source, and the slider can generate a straight line punching action. The visit also has two input power sources that can provide constant speed and variable speed, and the two-input power is accurately connected to the slider by the speed transmission group; and, on the source? There is an inertial energy storage device, the inertial energy storage device is placed in a fine touch to store energy, and the corresponding (four) work, y in the instant of punching a large amount of energy 4, and only a small power source can reach its ΐ ' The power source that can provide variable speed rotation is used to adjust the slider and the moving curve to achieve the control of the slider. Compared with the traditional mechanical punching machine, the differential transmission of the Wei Liling service punch can be processed for non-type processing. Good effect' and effectively reduce the noise of the punching machine and prolong the service life of the mold. Compared with the single-power source servo punching machine, the invention can provide a large punching capacity under the specifications of the same servo motor. 6 200800587 [Embodiment] As shown in FIG. 2 to FIG. 2, basically, the dual-powered wood of the differential transmission of the present invention is mainly composed of a slider group 1, and a movable group capable of rotating at a constant speed. A power source 3 for providing variable speed rotation, and a differential transmission group 4, such that the ghost group 1 is provided with a slider 12 in a hollow slider seat 11, which can generate a straight line in the slider holder 11. Limit movement. Force If the power source 2 for constant speed rotation is provided on the punching machine, there is a movement 22, and the machine is equipped with a certain speed rotation 1 by 22, which is the fixed speed shaft rotation shaft! By: - flywheel a; wherein 'the fixed speed of the power, check Jf5 has a pulley 221, and a belt 222 is connected to the flywheel Λ '俾 so that the power motor 21 can drive the fixed speed shaft 22 The rotating power source 3 is provided on the punching machine.
