Description

Technical Field

[0001] The invention relates to the technical field of bottle cap production, in particular to a bottle cap edge wrapping production process. Background Art

[0002] In the production process of snap-on bottle caps, the edge of the bottle cap needs to be stamped and formed, and the stamping and forming of the edge needs to be carried out through a mold. The existing edge forming mold has certain defects in the accuracy of the stamping position, and there are many structures for stamping on the mold, and the operation during installation is also more complicated.

[0003] like Fig.11 As shown, in the prior art, the buckle-type bottle cap is usually hemmed by directly punching out the buckle structure through a stamping die. After the buckle is stamped and formed, the buckle will protrude from the blank. At this time, the blank needs to be flattened by the stamping die, and finally the blank is cut. The existing hemming production process requires three steps to achieve the final shaping of the hemming; in the production and processing of large quantities of bottle caps, each step needs to be processed by a separate device. The production area occupied by these devices is quite large, and corresponding personnel must be equipped to operate them at the same time. The production cost is high, and the processing efficiency of the bottle caps is not high.
