Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen springs, in particular to a feasible high-temperature resistant water-cooled nitrogen spring structure. Background Art

[0002] Nitrogen spring is a new type of elastic component that uses high-pressure nitrogen as the working medium. It has small size, large elastic force, long stroke, stable operation, precision manufacturing, long service life, flat elastic force curve, and no need for pre-tightening. Nitrogen spring has a wide range of uses and its appearance meets the requirements of the times.

[0003] At present, there are many high-temperature resistant environments for nitrogen springs. Traditional nitrogen springs lack the effect of high-temperature resistance. After the internal high-pressure nitrogen moves up and down repeatedly for compression during long-term use, it will gradually generate higher temperatures. In high-temperature environments, the seals of nitrogen springs are prone to deformation and damage, leading to gas leakage. Precision parts will also produce thermal expansion reactions, which seriously affect the service life of nitrogen springs. In addition to using high-temperature resistant seals inside the product, corresponding measures need to be taken for the cooling of the product to prevent excessive temperature from affecting its life and the risk of cylinder explosion. Therefore, the internal structure of the cylinder of traditional nitrogen spring parts adopts the method of connecting water circuit circulation cooling, so that the temperature can be taken away by cooling water to achieve the purpose of cooling. At present, the internal water circuit of the cylinder is difficult to process or cannot be processed. Because the cylinder is cylindrical and has limited wall thickness, if 3D metal printing technology is used, bubble holes will be generated inside the structure, resulting in insufficient strength, limited pressure resistance, and easy cylinder explosion.
