Abstract
The invention relates to a main cylinder sealing structure for a six-axis numerical control frame type hydraulic press. The structure comprises a plunger piston, a main cylinder, a guide sleeve and a dustproof ring, wherein the guide sleeve and the dustproof ring are arranged between the plunger piston and the main cylinder. The structure is characterized in that a combined sealing structure is arranged between the plunger piston and the main cylinder and divides the plunger piston and the main cylinder into an upper lubricating cavity and a lower lubricating cavity; the upper lubricating cavity is filled with high-pressure oil through a high-pressure oil port of the main cylinder to realize sealing; the plunger piston in the lower lubricating cavity is provided with a self-lubricating structure, and the self-lubricating structure is arranged in the self-lubricating cavity through a flange plate and a fastening piece; the flange plate is provided with an oil return port; and a sealing ring is arranged between the flange plate and the plunger piston. In conclusion, the invention is more suitable for working conditions of serious unbalance loading; the sealing structure improves the sealing property and also prolongs the service life of parts; and the adopted combined sealing structure has compensation, thus the replacement of the sealing structure is reduced so as to reduce the maintenance cost. In addition, the invention also has the advantages of compact structure and the like and is convenient for mounting and disassembly.
