Novel piston rod mechanism of forging and pressing machinery

Abstract

Disclosed is a novel piston rod mechanism of forging and pressing machinery. The novel piston rod mechanism is characterized in that sealing rings are mounted on two sides of a bearing seat, a piston rod is mounted in the middle of the bearing seat, oil supply grooves are formed in the left side and the right side of the piston rod, an oil seal is arranged on each oil supply groove, and a double-fixing copper sleeve is mounted on the outer side of each oil supply groove and on the inner side of the corresponding sealing ring and mounted on the bearing seat through an own hole; oil inlets and oil return ports are arranged on the bearing seat and the double-fixing copper sleeve, so that lubricating oil is stored in the oil supply grooves after entering the double-fixing copper sleeves and flows out from the double-fixing copper sleeve through the oil return ports of the bearing seat after the oil supply grooves are filled with the lubricating oil to form good circulatory lubrication.

Description

technical field [0001] The invention relates to a piston rod mechanism, in particular to a novel forging machinery piston rod mechanism, which belongs to the technical field of forging machinery. Background technique [0002] The forging mechanical piston rod mechanism is an important component of forging equipment. At present, in the existing forging equipment mechanical piston rod mechanism, the flat end structure is generally used. Since the forging mechanical piston rod needs to pass through the copper sleeve and communicate with the oil supply tank, Both can achieve the normal up and down movement of the piston rod under the condition of sufficient lubricating oil supply. However, since the outer side of the copper sleeve is equipped with a sealing ring, it is difficult for the lubricating oil to enter the oil supply groove. Therefore, the existing forging mechanical piston rod The mechanism has the defects of difficult oil supply, large wear of the piston rod mechanism...

AI Technical Summary

Problems solved by technology

[0005] Beneficial effects: Since the present invention adopts the structure of the oil inlet and the oil return port to connect with the lubricating mechanism, it ensures that the piston rod always has sufficient lubricating performance during the up and down movement, so the present invention has smooth oil supply and lubricating performance. Good, the advantages of less piston rod wear and long service life of the piston rod have achieved the purpose of the present invention, and effectively overcome the difficulty of oil supply in the piston rod mechanism of the existing forging machinery, which leads to large wear of the piston rod mechanism and the use of the piston rod. Short life defect
