Description

Reinforcing structure of a sheet metal bending part

technical field

The utility model relates to the field of support structures, in particular to a reinforcement structure of sheet metal bending parts.

Background technique

A large number of sheet metal structures are used in aircraft. Conventional sheet metal parts have no load-bearing structure after bending, and will bend and deform when subjected to a small load. For bending sheet metal parts with load-bearing structures, the weight requirements in aircraft are often very strict. In order to increase the load, a reinforcing rib is welded or riveted on the sheet metal structure to increase the carrying capacity of the sheet metal, but the added structure not only increases the cost, reduces the stability of product quality, but also increases the weight of the product.
