Forging machine air cushion structure

Abstract

Disclosed is a forging machine air cushion structure. The forging machine air cushion structure is characterized in that a silica gel filling cushion is placed at the bottom of a structure body, a piston rod is mounted at the middle end of the structure body and connected with a piston, the piston is mounted in a cylinder and can move up and down in the cylinder, and silica gel buffering cushions are mounted on the piston and fixed on an up-down cover of the piston through own bolts. Silica gel has a good buffering function; when the piston is positioned at the highest or lowest position, the silica gel buffering cushions firstly contact with the inner surface of an up-down cover of the cylinder; the silica gel filling cushion is elastic, so that impact of the inner surface of the up-down cover can be effectively avoided, and the forging machine air cushion structure has the advantages of less proneness to being damaged, good die protecting performance, convenience in maintaining and difficult-to-damage piston rod.

Description

technical field [0001] The invention relates to an air cushion structure, in particular to an air cushion structure of a forging press, belonging to the technical field of forging machinery equipment. Background technique [0002] The air cushion mechanism of forging press is a commonly used functional part of forging machinery and equipment. Its main function is to withdraw the workpiece in the mold from the mold. In the current air cushion structure of forging press, since the air cushion structure is at the highest or lowest position Among them, the upper and lower sides of the piston often collide with the inner surfaces of the upper and lower covers of the cylinder in blind spots. Therefore, the existing forging press air cushion structure has the defects of easy damage to the air cushion, easy damage to the mold, difficult maintenance, and easy damage to the piston rod. Contents of the invention [0003] The object of the present invention is to provide a forging...

AI Technical Summary

Problems solved by technology

[0005] Beneficial effects: Since the silica gel material used in the present invention has a good cushioning function, when the piston is at the highest or lowest position, the silica gel cushion first contacts the inner surface of the upper and lower covers of the cylinder, and the silica gel filling pad springs, which can effectively Avoiding the impact on the inner surface of the upper and lower covers, so that the overall air cushion structure has the advantages of undamaged air cushion, good mold protection performance, convenient maintenance, and undamaged piston rod, which achieves the purpose of the present invention and effectively overcomes the problems caused by the air cushion of the existing forging press. Existing defects such as easily damaged air cushions, easily damaged molds, difficult maintenance, and easily damaged piston rods
