Description

technical field [0001] The invention relates to the field of additive technology, in particular, to an additive processing equipment and a processing method. Background technique [0002] With the development of manned spaceflight, the demand for space stations is increasing. Limited by the rocket's carrying capacity, the cabin of the space station needs to be made of lightweight high-strength aluminum alloys with thin-walled ribbed cabin components. In production and processing, the existing processing method of the thin-walled rib panel cabin body is to decompose the whole into several parts first, and after the parts are manufactured through traditional casting, forging, heat treatment and machining processes, each part is then Connected into integral components by welding, riveting, gluing and other processes. This conventional forming method generally has complex processes in each link, especially the connection between the various components by welding, the probabili...

AI Technical Summary

Problems solved by technology

This conventional forming method generally has complex processes in each link, especially the connection between the various components by welding, the probability of structural defects in the connection is relatively high, and the internal stress of welding is also large. On the one hand, the structural defects caused by welding Severely restricts the overall bearing capacity of the structural parts. On the other hand, the welding stress deformation makes it difficult to meet the design requirements for the dimensional accuracy of the components, and the low yield also leads to high costs.
