Development and development of automatic graphic generation method in bolt flange connection static sealing system

1 Parameterized generation of part drawings Because parameterized drawing can improve the design and drawing speed, combined with the features of the bolt flange connection system and the ability of AutoCAD2000 to process non-graphic information, the following describes how to realize the bolt flange connection static sealing system. Part drawing parameterization

1 Parameterized generation of part drawings Because parameterized drawing can improve the design and drawing speed, combined with the features of the bolt flange connection system and the ability of AutoCAD2000 to process non-graphic information, the following describes how to realize the bolt flange connection static sealing system. Parametric design of part drawings.

The drawing design process of a mechanical product is essentially a process of establishing and gradually refining a geometric model, which is described by data. See the main scheme of the part graph parameterization implementation.

The main part design manual of the part drawing parameterization refers to the standard of bolts, flanges and gaskets.

The structural diagram of the dimensioning, tolerance and surface roughness of the part drawing from the long neck butt welding flange is based on the two-dimensional graphic data structure. The graph theory and grammatical basis for automatically marking the mechanical pattern size have been proposed. To the graph adjacency matrix judgment method, but both have great difficulties in practical application to determine, for example: if the material of the flange in the information model is greater than 30mm and 16MnR should be added to the technical requirements in normalized In this way, the drawings can be managed in a unified manner, and the technical requirements can be modified in the same way as the title bar.

In the current various two-dimensional parametric CAD systems, it is rare to be able to automatically generate assembly drawings.

Environmentally friendly lubricant additives are receiving increasing attention. Starting in our country, we believe that new environmentally friendly tribological additives, especially friction polymers, should be developed according to different conditions of lubrication conditions.

5 Conclusion Foreign countries are actively carrying out research and development work on environmentally friendly lubricants, and developing speed. Domestic research on environmentally friendly lubricants has not yet been systematic, so it is necessary for us to carry out this work immediately.

(1) Investigate the environmental impact of various base oils and additives, study the compatibility of environmentally friendly base oils with various additives, and their tribochemical properties, and develop a new generation of environmentally friendly lubricants to meet the needs of the times. .

The development of environmentally friendly lubricants is a continuous development of systems engineering and a complementary research direction for the oil energy crisis. We must promote the advantages of environmentally friendly lubricants, improve their shortcomings, and lay the foundation for the development and application of environmentally friendly lubricants.
