Gas injection sealing machine for compressing and locking gas springs

Abstract

Disclosed is a gas injection sealing machine for compressing and locking gas springs. The gas injection sealing machine comprises a gas injection device body, a gas inlet, a hydraulic cylinder and a sealing plug cover. A notch corresponding to the rear portion of a gas spring cylinder is formed in the front portion of the gas injection device body, the rear portion of the gas spring cylinder barrel is arranged in the notch in the front portion of the gas injection device body, and the rear portion of the gas spring cylinder is hermetically connected with the notch in the front portion of the gas injection device body; an actuating rod is arranged on the front portion of the hydraulic cylinder, a notch corresponding to the actuating rod on the front portion of the hydraulic cylinder is formed in the rear portion of the gas injection device body, and the actuating rod on the front portion of the hydraulic cylinder is arranged in a notch in the rear portion of the gas injection device body, is hermetically connected with the notch in the rear portion of the gas injection device body, and abuts against the sealing plug cover; and a gas inlet is formed in the upper part of the gas injection device body, and the gas injection device body is filled with high-pressure nitrogen. According to the gas injection sealing machine for the compressing and locking gas springs, firstly, gas is injected into the cylinder, then the cylinder is sealed, and the processed and manufactured gas springs are accurate in pressure, stable in pressure value and high in safety.

Description

technical field [0001] The invention relates to the technical field of gas spring processing, in particular to a compressed and lockable gas spring injection sealing machine. Background technique [0002] Gas spring is an industrial accessory that can perform functions such as support, buffer, brake, height adjustment and angle adjustment. The gas spring mainly includes a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, and a filler, etc. The filler can be an inert gas or a mixture of oil and gas, an internal control element and an external control element (referring to a controllable gas spring) and joints. The principle is to fill the closed pressure cylinder with an inert gas or an oil-gas mixture, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and the pressure difference generated by the cross-sectional area of ​​the piston rod is smaller than that of the piston. To realize the movement of t...

AI Technical Summary

Problems solved by technology

Compression and lockable gas springs generally use gaps or pressure steel balls to block gas injection. These two gas injection methods are slow, inaccurate, low in efficiency, and poor in safety, and cannot meet the requirements of gas spring processing and use.
