Description

Sheet metal bonding structure

This creation is related to the sheet metal structure, in particular it refers to a sheet metal joint structure that can ensure its dimensional accuracy after being assembled, and at the same time achieves a reliable waterproof, impact-resistant and impact-resistant sheet metal joint structure.

By the way, items made of sheet metal are quite common in the market. Generally, sheet metal is joined by riveting or welding. In terms of welding methods, spot welding and full-circle welding are currently widely used sheet metal joining methods. Spot welding is only to make the two metal plates easy to join. Full-circle welding is to melt the solder into the two metal plates during welding. Although the bonding position has better bonding strength after welding, the temperature generated by the full-circle welding is quite high. Therefore, the surrounding position of the metal plate welding part is prone to bending deformation due to the high temperature of the welding, resulting in dimensional deformation, which will cause subsequent Assembling troubles, therefore, in some sheet metal applications that require high dimensional accuracy, riveting or spot welding is usually used to join the metal plates to form the required sheet metal structure.

However, the sheet metal structure made by riveting or spot welding will inevitably have a gap in the joint position of the two metal plates, which cannot achieve 100% waterproof effect, which limits the scope of its subsequent applications. Therefore, how to provide a Ensuring the dimensional accuracy after the sheet metal structure is composed, and at the same time achieving a sheet metal joint structure that can be reliably waterproof and impact-resistant is the primary issue that this creation intends to solve.

Preferably, the glue layer has a top edge, and the top edge of the glue layer is lower than the extension height of the top ends of the first plate and the second plate respectively, so that the first plate and the second plate A drainage channel extending along the top edge of the glue layer is formed in between.
