Abstract

The invention provides a nitrogen cylinder structure capable of prolonging the service lifetime. The nitrogen cylinder structure comprises a piston rod, a fixed part, a moving part, a nitrogen cylinder body, an isolation protection block, a protection sleeve and a sealing device, the moving part is arranged at the upper end of the piston rod, the piston rod is arranged in the nitrogen cylinder body, the sealing device is arranged at the inner sides of the piston rod and the nitrogen cylinder body, the fixed part is arranged at the outer side of the moving part, and the nitrogen cylinder body is connected with the fixed part through the isolation protection block. According to the structure, the goals of reducing abrasion of the sealing device and the piston rod and prolonging the service lifetime of the nitrogen cylinder can be achieved.

Description

technical field [0001] The invention belongs to the technical field of stamping die manufacturing, and in particular relates to a nitrogen cylinder structure capable of prolonging service life. Background technique [0002] With the widespread application of nitrogen cylinders in the field of stamping die manufacturing, the proportion of its purchase cost in the die manufacturing cost continues to increase. Prolonging the service life of the nitrogen cylinder is becoming more and more important for controlling the cost of mold use. The sealing performance of the nitrogen cylinder is a major factor affecting its reliability and service life. During the use of the nitrogen cylinder, dust is easily affected by the air flow and gathers on the surface of the piston rod, and rubs against the sealing device of the cylinder port through the movement of the piston. As a result, the sealing device and the piston rod are worn, which in turn leads to failure and air leakage, which gre...
