AI Technical Summary

Technical Problem

Traditional casting cable saddles have problems such as high energy consumption, high pollution, low mechanical properties and long manufacturing cycles, which are difficult to meet the high strength and lightweight needs of large-span suspension bridges.

Method used

The forging process is used instead of the casting process. Through the structural design of forging and welding, the cable saddle structure is decomposed for forging and welding. Combined with the use of high-strength steel plates, the strength and lightweight effect of the cable saddle are improved, and the welding difficulty is reduced through reasonable planning of the welding process.

Benefits of technology

It realizes high strength and lightweight of cable saddles, reduces material usage and processing costs, improves product quality and manufacturing efficiency, and meets the high performance needs of large-span suspension bridges.

Abstract

The present invention relates to the application of forging and welding technology in the manufacturing and forming of suspension bridge saddles, and specifically discloses a forging and welding forming process of the main saddle of a suspension bridge, wherein the main process flow involves: (1) forming a seat plate and a bottom plate of a saddle groove by a forging process, (2) cutting various components of the saddle body structure and the side wall plates of the saddle groove; (3) welding the bottom plate of the saddle groove and the side wall plates to obtain the saddle groove, and (4) planning the welding sequence of the plates of the saddle body structure to obtain the optimal welding space and welding quality. In the traditional process, the saddle groove is usually formed by casting, resulting in low quality and strength. In the present scheme, the bottom plate of the saddle groove is formed by forging to achieve the purpose of light weight and improved strength.
