High-strength aluminum alloy cabins are commonly used in multiple models of products from the 211 factory. In the past, the products of this type of cabin section were mainly cast and forged, but there were &#8220;defects&#8221; in the production of casting and forging. In the pre-research stage of a key model, the factory proposed to adopt an additive manufacturing method, which was approved by the design department.<br \/>\nHowever, the rough weight of the cabin section is too large, which exceeds the load-bearing limit of the working platform of the arc additive equipment. The research team independently researched the structure of the working platform, removed the waste weight of the platform, and designed and manufactured the &#8220;eight claw&#8221; structure tooling, which not only greatly reduced the weight of the platform, but also maximized the size of the formed parts. However, as soon as the cabin section was put on the shelf, the problem reappeared. Due to the characteristic structure on the inner wall, the cabin section needs to be turned 90 degrees and then formed. However, the cabin section is too heavy, and the turning is susceptible to inertia, resulting in a position shift. The research team designed a positioning and card installation plan without increasing the weight, which solved the problem of cabin offset in the printing process. The factory successfully mastered the 3D printing technology of cabin products.<\/p>\n<div class=\"37c28470d9d6d3cb9ff74e663adb766a\" data-index=\"2\" style=\"float: none; margin:0px 0 0px 0; text-align:center;\">\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3594734025006597\"\r\n     crossorigin=\"anonymous\"><\/script>\n<\/div>\n\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>In 2021, the development of China&#8217;s aerospace industry is in full swing.
