<p>The present invention relates to a fine adjustment apparatus for a hydraulic press and, more specifically, to the fine adjustment apparatus for the hydraulic press which can facilitate accurate and rapid production of a product without regard to viscosity of a liquid inputted into a hydraulic cylinder, and also can prevent a mold from being damaged due to impact of the hydraulic cylinder. According to the fine adjustment apparatus of the hydraulic press which forms the product by driving the hydraulic cylinder up and down, a load part is formed on an upper part and a lower center of a piston, and a cylinder has a protruded piece formed on an upper side of the upper load part. A cylinder housing has a ram room so that the piston (12) of the cylinder is inserted and moves up and down, and has a descending port and an ascending port to supply and discharge a fluid supplied from a hydraulic supply apparatus to/from the ram room. A pressurizing control valve is installed on the upper surface of the cylinder housing, and can block the descending port of the cylinder housing by being pressurized by the protruded piece of the cylinder.</p> |
