Abstract

The invention discloses a permanent magnet high pressure nitrogen spring which comprises a cylinder body, a permanent magnet A, a permanent magnet B, a permanent magnet C, a permanent magnet D, a gas charging valve, a rod piston, an upper end cover, a rodless movable piston and a lower end cover. A cavity A is formed in a piston rod. The permanent magnet A is installed at the bottom of a piston body. The piston body and the permanent magnet A are provided with a gas walking hole A. The permanent magnet B and the permanent magnet C are installed inside the rodless movable piston. The rodless movable piston is provided with a gas walking hole B. A cavity B is formed between the rodless movable piston and the piston body. The top of the lower end cover is provided with the permanent magnet D. The lower end cover is provided with a gas walking hole C. A cavity C is formed between the lower end cover and the rodless movable piston. The permanent magnet high pressure nitrogen spring overcomes defects in domestic and foreign technology and has the very important significance in improving safety, stability and buffering capacity of the nitrogen spring in industries such as mold manufacturing, saving energy, improving the product quality and reducing the product cost.

Description

technical field [0001] The invention relates to the technical field of elastic elements, in particular to a permanent magnet high-pressure nitrogen gas spring. Background technique [0002] In terms of the development of nitrogen gas springs, Germany and the United States are at the forefront of the world. The mold nitrogen gas spring developed by FIBRO Company of Germany and DADCO Company of the United States has been widely used in many industrial fields. But so far the world does not have an effective method for high and low pressure alarms and compensations for nitrogen gas spring systems. However, the research on the application of mold nitrogen springs in my country is in its infancy. Although some achievements have been made, there is still a big gap with foreign products in terms of performance. At the same time, the same problem exists: "the service life of mold nitrogen springs is When the mold closing height is small and the stroke is required to be long, ordinar...
