Mirror polishing process of nitrogen spring piston rod

Abstract

The invention discloses a mirror polishing process of a nitrogen spring piston rod. The mirror polishing process of the nitrogen spring piston rod comprises the following steps of S1, nitriding; S2, removing the nitriding color; S3, spraying five-star diamond oil; S4, spray coating a diamond grinding paste; S5, fixing a nitrogen spring piston rod shaft; S6, pressing the end surface of a nitrogen spring piston rod; and S7, polishing. According to the mirror polishing process of the nitrogen spring piston rod provided by the invention, the smooth finish of the polished nitrogen spring piston rodcan be ensured, the scratches on the surface of the nitrogen spring piston rod are reduced, and the nitrogen spring piston rod can be lubricated conveniently by utilizing the five-star diamond oil soas to be polished conveniently; the surface of the nitrogen spring piston rod can be efficiently polished by utilizing the diamond grinding paste, so that the smooth finish of the surface of the polished nitrogen spring piston rod is further ensured, and the polishing demands of people are met; and the polishing process is simple to operate, high in polishing efficiency and convenient to use by people.

Description

technical field [0001] The invention relates to the technical field of nitrogen spring piston rod processing, in particular to a mirror polishing process for nitrogen spring piston rods. Background technique [0002] Mold-specific nitrogen spring is a new type of elastic component with high-pressure nitrogen as the working medium. It has small size, large elasticity, long stroke, stable operation, precise manufacturing, long service life, gentle elastic curve, and no need for preloading, etc. It has tasks that are difficult for conventional elastic components such as metal springs, rubber and air cushions. It simplifies mold design and manufacturing, facilitates mold installation and adjustment, prolongs the service life of molds, and ensures stable product quality. It can also be designed as a nitrogen spring system. As a part of the mold, it can easily realize constant pressure and time-delay action in the system. It is a new generation of the most ideal elastic component ...

Problems solved by technology

However, the process of traditional nitrogen spring piston rod processing is complex and inconvenient to polish. The surface roughness of some nitrogen spring piston rods is around Ra0.08-0.10, so the surface of nitrogen spring piston rods is relatively rough, and the surface of nitrogen spring piston rods is polished Wheel polishing, easy to produce microscopic cracks and burns on the surface of the workpiece, and the fine grinding marks on the surface cannot be effectively eliminated

Therefore, the traditional processing technology not only cannot guarantee the smoothness of the nitrogen spring piston rod, but also increases the cost of polishing, and is not convenient for people to use. In view of this, we provide a mirror polishing process for the nitrogen spring piston rod
