Precautions For The Use Of Nitrogen Gas Springs

The mold nitrogen gas spring is an elastic component with high pressure nitrogen as the working medium, which requires customers to install and use it correctly to ensure its safety, reliability, expected use effect and ideal service life. The following content, the editor of Shiruida has sorted out some precautions for the use of nitrogen gas springs:

Precautions for the use of mold gas springs

1. Ensure that the workpiece pressed against the upper end of the piston rod of the nitrogen gas spring of the mold is completely fitted with the piston rod during movement, and the hardness is sufficient. After the nitrogen gas spring is compressed, it must not return freely, which will easily damage the nitrogen gas spring and seriously affect the life of the spring. (According to past experience, this is the cause of the most damage to the gas spring)

2. The movement direction of the top of the piston rod pressing the workpiece must be parallel to the piston rod; the contact surface of the workpiece on the top of the piston rod should be perpendicular to the axis of the piston rod, and eccentric load is not allowed.

3. In theory, the production stroke S of the die gas spring can be fully utilized. In actual use, we recommend using the full stroke to prevent the nitrogen gas spring from being overloaded due to mold replacement or other reasons exceeding the stroke. It is recommended to use 90% of the stroke S.

4. It is strictly forbidden to place the nitrogen gas spring in the environment of exposure and high heat source, and the maximum allowable temperature is +80℃. (Of course, except for the special high temperature resistant nitrogen gas spring)

5. The nitrogen gas spring cannot be disassembled at will. Maintenance requires professional personnel to complete.

As a new type of product that can simplify the production and design of molds, save product design and mold production, mold nitrogen springs need to pay attention to the above-mentioned items in use to ensure that they can bring you the expected use effect.
