Transmission of servo punch press

The utility model discloses a transmission of servo punch press, it includes: a machine support. The eccentric wheel, the eccentric wheel can be equivalent to that the frame makes rotary motion, power component, power component is connected with the eccentric wheel transmission so that its drive eccentric wheel is rotatory for the frame, transmission spindle unit, the transmission spindle unit rotatably support in the frame, go up the connecting rod, the one end that goes up the connecting rod articulates the eccentric department at the eccentric wheel, the other end of going up the connecting rod articulates the eccentric department at transmission spindle unit, the slider, the slider cunning is joined in marriage on the guide rail of servo punch press, lower connecting rod, the one end of connecting rod articulates on transmission spindle unit down, and the other end is articulated mutually with the slider. The utility model discloses can improve the pressing speed and the pressurize ability of press in the servo punch press to adapt to different technologies, different material and the requirement of thickness to some special forming technology such as influence of deformation velocity.
