Abstract:

In order to reduce the cost in reconstruction engineering for old equipment, the conception of virtual reconstruction equipment is presented. The prin ciple and characteristics of virtual reconstruction are discussed based on virtual manufacturing techniques. The manufacturing system for non-refillable  steel welded cylinders for industry use is built, and appropriate welding tool machines are reconstructed. The structure and working principle of virtu al prototypes are shown in the design process. The result shows that the welding tool machine＇s structure is simple, and the cost is low, and can satis  sfy the technology requirements in the production.

Key words: （virtual design;virtual manufacturing;virtual reconstructing;non-refillable steel welded cylinder f or industry use）
