What are the structural forms of nitrogen gas springs?

Time:2021-05-23    Edit by TengFei

Nitrogen gas spring for molds (referred to as die gas spring or nitrogen gas spring or nitrogen cylinder or nitrogen cylinder) is a new type of elastic component that uses high-pressure nitrogen as the working medium. It is small in size, large in elasticity, long in stroke, stable in work, precise in manufacturing, and suitable for use. Long life (one million times), flat elastic curve, and no need for pre-tensioning, etc. What are the options for the structure of the nitrogen gas spring? First of all, it is necessary to determine its structure, and comprehensively consider factors such as mold structure, equipment, working environment, working conditions, mold cost and adjustment and maintenance according to the stamping process requirements of the required parts.


1. Pipeline connection type:

Pipeline connection type is generally used in large stamping parts and large covering parts. It uses a high-pressure tube to connect the individual nitrogen gas springs together, and then installs a control instrument to make the spring pressures of the nitrogen gas springs of the entire system equal, so that the entire system is integrated, equivalent to an independent gas spring. In this way, a greater balance of elastic force and elastic force transmission is obtained, the life of the mold is improved, and the quality of the stamping parts is guaranteed.

2. Freestanding:

The most widely used is the independent nitrogen gas spring, which occupies a relatively small mold space, is placed tightly, and has various structural forms. The following different installation forms do not require any accessories. It can be used directly by placing it in the mold. It is the design form chosen by designers today.
