Abstract
Apparatus for lubricating die and/or workpiece surfaces, the apparatus including a container adapted to capture a predetermined volume of lubricant. At least one nozzle is provided for spraying the volume of lubricant onto the die/workpiece surfaces when the volume is received from the container. A first valve is connected between the nozzle and container, and a reservoir of lubricant and a pump for circulating lubricant through the container and past the first valve at a relatively low pressure is provided, the circulation of lubricant occurring during a portion of a lubricating cycle when no lubricant is sprayed onto the die/workpiece surfaces. A second valve is located between the pump and container for interrupting the flow of lubricant past the first valve, and a blocking valve is located between the container and the reservoir for interrupting the flow of lubricant from the container. A piston is located within the container and an actuator is connected to the piston for moving the same within the container to direct the captured volume of lubricant from the container to the first valve at a pressure sufficient to open the first valve.
