⚙️ The working principle and function of the rivet machine (taking the electric contact rivet machine as an example)

A rivet machine is a specialized device that uses pressure or impact to firmly connect metal contacts (such as copper or silver) to metal sheets or terminals.
The entire process does not require heating or welding, so there is no risk of welding slag, oxide layers, or unstable resistance.

🧭 1. Automatic Feeding

The machine is equipped with an automatic vibrating plate or feeding mechanism to feed the rivets (contacts) and workpieces into designated positions, enabling fully automatic loading and reducing manual labor.

🧲 2. Precision Positioning

The workpiece and rivet are precisely positioned in the fixture using a pneumatic cylinder or servo system, ensuring precise contact-to-metal bonding and preventing misalignment and scrap.

🛠️ 3. Riveting and Forming

A spindle (or servo motor) applies downward pressure, using cold pressing or impact forming technology to securely bond the rivet to the workpiece at room temperature. This riveting method does not compromise the electrical conductivity of the contacts or cause thermal deformation.

🔩 4. Pressure Control

The machine's built-in pressure sensing system automatically detects and controls the pressure of each riveting operation, ensuring consistent riveting results, stable strength, and a smooth, trace-free surface for every product.
