Description

Technical Field

[0001] This utility model relates to the technical field of descaling devices, specifically a shot blasting device for descaling automotive frame rivets. Background Technology

[0002] Rivets are key components connecting various parts of a car's frame. They provide sufficient strength to ensure safety by supporting the weight of the entire vehicle and the impact of driving. They also have advantages such as weight saving, easy installation, and disassembly. They are mostly made of high-strength steel such as No. 45 steel, with a nominal diameter between M4 and M20. The length depends on the frame structure. The surface is often treated with galvanizing, nickel plating, or hot-dip galvanizing. There are two types of riveting: cold riveting and hot riveting. In terms of removal, traditional methods such as gas cutting, drilling, and chiseling are inefficient and can easily damage the frame. Currently, hydraulic or electric handheld rivet guns are commonly used to achieve precise, efficient, and non-destructive removal.

[0003] The equipment used for shot blasting to remove oxide scale from automotive frame rivets is usually a shot blasting machine. Its working principle is to accelerate the shot and propel it onto the rivet surface through a high-speed rotating impeller, using the impact force of the shot to remove the oxide scale.

[0004] This application improves upon the existing technology. In the existing technology, the existing shot blasting device for removing oxide scale from automotive frame rivets is not convenient for screening automotive frame rivets and shot after shot blasting to remove oxide scale from automotive frame rivets, which will reduce the production efficiency of automotive frame rivets.
