Description

Technical Field

[0001] This application relates to the field of sheet metal processing, and in particular to a device for automatically riveting sheet metal parts. Background Technology

[0002] The television casing is a crucial component of a television set, typically made of metal or alloy materials and manufactured through processes such as stamping, bending, and stretching. It serves to protect internal components, support the television's structure, and enhance its appearance. As a type of sheet metal part, the television casing plays a vital role in the television manufacturing process, and its quality directly impacts the overall performance and user experience of the television.

[0003] Television casing panels require rivets to connect to other components, typically installed using a press. One type of television casing panel requires three rivets on the front and four on the back. However, existing presses can only rivet one or both sides of the panel. After riveting one side, the panel must be manually flipped over to complete the riveting of the other side. This process is inefficient and prone to missing rivets, affecting production quality. Summary of the Invention

[0004] To improve processing efficiency, this application provides an automatic riveting device for sheet metal parts.
