[0002] The easy-pull bottle cap is a common beverage sealing device. Usually, in order to facilitate the drinker to open it, the manufacturer will set a pull ring on the easy-pull bottle cap to assist the opening of the bottle cap, so that the drinker can complete the beverage without using tools. However, since the pull ring of the easy-open lid usually has a sharp edge profile, it needs to be riveted and folded during processing, so that the edge will not scratch the drinker's hand when opening it, and the The usual riveting process is mostly realized through the cooperation of multiple sets of molds, which is inconvenient and inefficient, so there is a certain capacity limitation, which restricts production efficiency

Embodiment Construction
[0028] Such as Figures 1 to 4 As shown in one, the easy-open bottle cap pull ring riveting mold of the present invention is used for stamping the easy-pull bottle cap pull ring blank 3, and the easy-pull bottle cap pull ring includes a riveting part 35 for riveting with the bottle cap and the draw ring part 36, there is a gap 33 between the draw ring part 36 and the riveting part 35, the trimming edge of the draw ring part 36 is provided with a first bending part 361, and the riveting part 35 The edges of the trimmed contours on both sides are provided with a second bending portion 351. The mold includes an upper mold 2 and a lower mold 1. The lower mold 1 is a stamping die and is provided with an opposite position and is used for the pull ring of the easy-pull bottle cap. The material inlet 11 and the material outlet 12 where the blank 3 is fed and output, and the lower die 1 is provided with a first punching recess 151 and a first die forming in sequence along the direction...

The invention discloses an edge riveting die for a pull ring of an easy-pulled bottle cap, and a forming method thereof. A first punching recession, a first compression recession, a second punching recession, a first trimming recession, a first shaping recession, a first flanging recession and a second shaping recession are sequentially arranged on a lower die in a direction from a charge port ofthe lower die to a discharge port, and a first punching bulge, a first compression bulge, a second punching bulge, a first trimming bulge, a first shaping bulge, a first flanging bulge and a second shaping bulge which correspondingly carry out matching action with the lower die are arranged on an upper die, so that the treatment of first-time punching, compression, second-time punching, trimming,first-time shaping, first-time flanging and second-time shaping are sequentially completed when a pull ring blank of the easy-pulled bottle cap is conveyed to the discharge port from the charge port of the lower die, the operation is simple and efficient, and the cost of the die can be saved, so that one die is capable of completing most of machining treatment for the pull ring blank of the easy-pulled bottle cap.
