Description

Technical Field

[0001] The utility model relates to the technical field of riveting, and more specifically, it relates to a riveting device for the production of radio frequency connectors. Background Art

[0002] The riveting device for the production of radio frequency connectors is an automated device specifically used for the production of radio frequency connectors. Its main function is to firmly connect the various components of the radio frequency connector through the riveting process.

[0003] In the existing technology, firstly, some devices may shake under high-pressure working conditions, affecting the riveting accuracy. It is impossible to quickly and accurately adjust the pressure of the lower die assembly, affecting production efficiency and product quality. Without the buffer design of the push frame and rubber block, it may lead to increased equipment wear and rising maintenance costs. Secondly, it will be cumbersome to replace the mold for some devices, reducing production flexibility, which may lead to unstable connection, affecting the consistency and reliability of the product. Lack of the automatic locking function of the lock frame and tension spring may cause the connection to fall off during high-speed production, posing a safety hazard. Finally, some devices cannot quickly and accurately position the clamping rod, and it is difficult to control the distance between the locking groove and the lock frame, affecting the processing accuracy of the product. The operator needs to manually adjust it, increasing the complexity and time cost of the operation. Summary of the Utility Model
