焊接結构在工程机械中的应用非常广泛。以我厂生产的几种挖掘机为例,焊接鋼結构占机器总重60～75%。設計焊接結构时,除了注意使用要求外,还必須使結构在生产准备和制造上既經济又簡单。但是,后者常为我們所忽視,对結构的工艺性問題注意不够。結果,影响产品制造周期,成本提高,有时还降低整个机器的質量和使用寿命。焊接結构的工艺性要求很多。本文仅提出下面几个問題,供大家参考。
Welding structures are widely used in construction machinery. Taking several excavators produced by our factory as an example, the welded steel structure accounts for 60 to 75% of the total weight of the machine. When designing a welded structure, besides paying attention to the use requirements, it is also necessary to make the structure economical and simple in production preparation and manufacturing. However, the latter is often overlooked by us. We do not pay enough attention to the technical problems of the structure. As a result, the product manufacturing cycle is affected, costs increase, and sometimes the overall machine quality and service life are reduced. The technical requirements of the welded structure are many. This article only proposes the following questions for your reference.
