The up-down and back-forward positions of the vibratory feeder and the rivet feeding track can be easily adjusted to ensure that the rivet can accurately slide down below the magnetic upper riveting die and be magnetically attracted by it.

[0026] It should be noted that the button rivet in this utility model is a semi-hollow rivet. A semi-hollow rivet is a type of rivet with a hollow structure at the tail. Its working principle is to form a permanent snap fastener by pressing the hollow part outwards. The core application scenarios are concentrated in light industrial industries such as clothing, footwear, and bags.

[0027] Specifically, the working principle and process of this utility model are as follows: First, the rivets to be riveted are placed into a vibratory feeder. The vibratory feeder's main function is to feed the rivets in an orderly manner. Electromagnetic vibration causes the rivets to move directionally along a spiral track, ultimately delivering each rivet to a T-shaped groove in the rivet feeding track. Under gravity, the rivets slide down the T-shaped groove to the U-shaped opening at the lower end, ensuring that the rivets enter the processing position sequentially and accurately, improving production efficiency. Then, the magnetic riveting die magnetically attracts the rivets, and the through-hole of the workpiece to be riveted passes through the positioning pin of the floating core die. The outward-pushing cylinder is activated to push the rivet feeding track outward, moving the U-shaped opening away from the magnetic riveting die to avoid affecting the riveting process. Finally, the hydraulic cylinder is activated to drive the magnetic riveting die. The rivet moves downwards until it passes through the hole in the workpiece. Simultaneously, the through hole at the lower end of the rivet fits onto the positioning post at the upper end of the floating die. The positioning post serves a positioning function. The magnetic upper riveting die continues to press down, forming a permanent snap-fit ​​by squeezing the hollow part at the lower end of the rivet outwards. Then, the workpiece is removed, and the next workpiece to be riveted is placed back on the floating die. The outward-pushing cylinder pulls the rivet feeding track inwards to reset it. Then, the next rivet continues to slide down to the lower end of the magnetic upper riveting die and is attracted by it. This process is repeated, which allows for rapid riveting, improves production efficiency, and ensures the accuracy and consistency of the riveting process, thereby improving product quality.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
