Description

Technical Field

[0001] This utility model relates to the field of hook riveting technology, specifically a hook riveting machine. Background Technology

[0002] A hook is a common mechanical connector or household component. Essentially, it is a device with a specific shape and structure that serves functions such as suspension, connection, and fixation. Structurally, a hook typically consists of a hook body and a connecting part. The hook body is generally curved. In mechanical assembly, the hook is riveted as a whole, primarily to ensure a reliable connection between the hook and other components. Riveting, as a connection process, ensures that the connecting parts are pressed together and form a stable mechanical bond.

[0003] However, in traditional hook riveting operations, the accuracy of riveting positioning has always been a key factor affecting production efficiency and product quality. During the riveting process, deviations and misalignments can easily occur between the hook and the part to be riveted due to angle and position issues during the riveting stamping process. When applying pressure, the riveting tool may not be able to accurately act on the predetermined position, resulting in the riveting point shifting. This leads to insufficient connection strength between the hook and the part, or even loosening and falling off, affecting the overall performance and reliability of the product and easily causing problems in subsequent production stages. To address this, we propose a hook riveting machine. Utility Model Content

[0004] One of the technical problems to be solved by this application is: when the hook is riveted, the overall shape may deviate or misalign due to angular position issues, resulting in the rivet point shifting and the connection between the hook and the component becoming loose or falling off.
