Abstract
The invention discloses a mechanical hydraulic combination-drive pressing machine, which comprises a mechanical power dive system and a hydraulic power drive system, wherein two systems can respectively work independently and also can work simultaneously. When the mechanical power drive system works independently, the performance is like that of an ordinary mechanical pressing machine, and a hydraulic cylinder can be used as the hydraulic cushion of the ordinary mechanical pressing machine; when the hydraulic power drive system of the mechanical hydraulic combination-drive pressing machine works independently, the characteristic that the hydraulic cylinder is small in inertia can be brought into full play, and a lower slider is driven to carry out high-frequency and small-range up-and-down movement, so that the punching stroke is greatly reduced and high-speed pressing is realized; when the mechanical power drive system and the hydraulic power drive system work simultaneously, the mechanical power drive system drives the slider-crank mechanism of the pressing machine to work, and the hydraulic power drive system can drive the lower slider to generate high-frequency vibration through the hydraulic system while an upper slider drives the lower slider to move downwards, so that the pressing machine has the working manner of vibration machining and satisfies the requirement of special techniques.
