Abstract
The utility model discloses a lubricating oil circulated lubricating and cooling structure for a ball head and a ball bowl of a high-speed blanking press. The lubricating oil circulated lubricating and cooling structure comprises a lubricating pump station (1). The lubricating pump station is installed on one side of a blanking press lower beam (29), connected with a lubricating oil inlet (6) of a sliding block cylinder body (3) for oil supplying, and connected with an oil chamber in a blanking press upper beam (28) for oil returning. A through oil hole (20) is formed in a guide column screw (8). An oil inlet (26) is formed in the center of the bottom of the lower ball bowl (21) and communicated with the through oil hole, and a piston opening (19) is formed in the side wall of a hydraulic cushion piston (7).
