[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This solution uses a traction chain to guide the semi-finished chain from the inlet guide rail to the cover plate. The servo sprocket begins positioning, and the feeding cylinder delivers two parallel outer plates from the feeding tube to the top of the semi-finished chain in one go. The magnetic seat holds the two outer plates, and the feeding cylinder retracts. The upper template begins to press down. First, the guide pin is inserted into the two holes of the outer plate to make the outer plate and the chain pin concentric. Then, the guide impactor presses down the two outer plates held by the magnetic seat and presses them into the pin. The upper template rises. Driven by the sprocket, the chain advances six links to the bottom of the protruding mold. The upper template begins to press down, causing the protruding mold on the protruding mold seat to press against the outer plate, creating a height difference between the pin and the outer plate. At this point, the chain protrusion is completed.

[0019] 2. In this solution, the servo motor drives the sprocket to advance the chain by six sections. The riveting head positioning cylinder extends and pushes out the riveting head positioning slider to insert into the chain. If the chain is misaligned, the sensor light will not be triggered, and the equipment will alarm. Once the chain is positioned, the hydraulic cylinder extends and the movable module descends, causing the riveting head block on the riveting head mold seat to press into the chain pins. Since the length of the riveting head block exactly covers the four pins, the riveting work of the ends of the four pins is completed in one go.

[0020] This invention requires only two workers to manually assemble the inner and outer links into a semi-finished chain, while one worker operates the machine, saving manpower and improving production efficiency. Furthermore, the current process enables the production of two outer pieces at once, so the punch press can simultaneously press in two outer pieces, and the current process speed reaches 126 meters per hour.

Then, the guide impactor 21 presses down the two outer pieces held by the magnetic seat 6, and presses in the pin. The upper template 14 rises back. Driven by the sprocket 35 driven by the servo motor, the chain advances 6 links to the bottom of the protruding mold 17. The upper template 14 begins to press down, so that the protruding mold 17 on the protruding mold seat 16 presses against the outer piece, so that the pin and the outer piece form a height difference. At this time, the protrusion of the chain is completed.

[0036] The servo motor drives the sprocket 35 to move the chain forward 6 links. The rivet head positioning cylinder 39 extends and pushes out the rivet head positioning slider 41 to insert the chain. If the chain is misaligned, the sensor light will not be triggered and the equipment will alarm.

[0037] Once the chain is positioned, the hydraulic cylinder 30 extends and the movable module 32 descends, causing the riveting block 46 of the riveting head mold seat 47 to press into the chain pins. Since the length of the riveting block just covers the four pins, the riveting work of the ends of the four pins is completed in one go.
