Description

Technical Field

[0001] The utility model relates to the technical field of liquid nitriding of stainless steel control rings, in particular to a loading and unloading fixture used for liquid nitriding of stainless steel control rings. Background Art

[0002] Liquid nitrogen treatment of stainless steel is a common metal surface treatment method, typically used to improve the hardness, wear resistance, and corrosion resistance of stainless steel. This treatment involves placing the stainless steel in liquid nitrogen for cryogenic treatment, typically at temperatures around -196°C. Liquid nitrogen treatment of stainless steel can increase the material's hardness and wear resistance, enhance its corrosion resistance, improve its overall performance, extend its service life, and reduce deformation and wear.

[0003] In order to improve the performance of the stainless steel control ring, it can be subjected to liquid nitriding treatment. The control ring is in the shape of a circular ring. Currently, it is usually hung on a bracket for fixation. The bracket does not have a clamping function for the control ring, resulting in poor stability of the control ring during liquid nitriding, thereby resulting in poor nitriding effect of the control ring.

[0010] As an optional solution of the technical solution of the present invention, it also includes: a side mounting block, one end of which is connected to the base and the other end is connected to the mounting block, for strengthening and fixing the mounting block.

[0011] As an optional solution of the technical solution of the utility model, a slide is provided on the fixed block;

[0012] The movable block is provided with a sliding edge;
