ABSTRACT:
An equalizer assembly that integrates into the die cutting station of a press and comprises two hydraulic actuators, each of which interacts with one of the jackscrews of the press to create an internal hydraulic pressure. The internal pressure of a first of the hydraulic actuators corresponds to a loading force that is imparted upon the rotary cutting die proximate to a first end of the rotary cutting die, and the internal pressure of a second of the hydraulic actuators corresponds to a loading force that is imparted upon the rotary cutting die proximate to a second end of the rotary cutting die. The hydraulic actuators are in fluid communication with one another such that the hydraulic pressures therein are maintained substantially equal to define an overall system hydraulic pressure, and the hydraulic actuators are designed and arranged so that the loading forces generated thereby are substantially equal. Therefore, in response to loading forces of the jackscrews, whether equal or unequal, the equalizer functions to automatically apply equal loading forces to the opposite ends of a rotary cutting die, whereby the rotary cutting die is evenly loaded. A hydraulic pump functions to selectively increase the system hydraulic pressure and a pressure gauge monitors the system hydraulic pressure.
