Embodiment 1
[0038] Before introducing the technical scheme of the present invention, first introduce the manufacturing method of bottle cap in the prior art, as figure 1 As shown, in the prior art, in order to maximize the number of bottle caps manufactured by one tinplate plate 1, a plurality of round iron sheets 2 for manufacturing bottle caps are distributed in a staggered parallel arrangement on the tinplate plate 1. But after cutting out a plurality of circular iron sheets, there are still a lot of leftover scraps, and the remaining scraps also have utilization value, such as can be made into an iron ring 12, which is convenient for people to open the bottle cap, and solves the difficulty of existing bottle caps. Open technical questions.
[0039]Yet, in order to utilize redundant leftover material to manufacture the iron ring 12 that solves the difficult opening of the bottle cap, the arrangement of the circular iron sheet 2 on the tin plate 1 has been redesigned, as figure 2 sho...
Embodiment 2
[0055] In addition, in order to achieve the above object, the present invention also provides a manufacturing method of the bottle cap.
[0056] Such as Figure 5 as shown, Figure 5 It is a schematicflow chart of Embodiment 2 of the manufacturing method of the bottle cap of the present invention.
[0057] In embodiment 2, the manufacture method of this bottle cap comprises the steps:
[0058] Step S10, draw a plurality of circular iron sheets 2 on a square iron sheet, each of the circular iron sheets 2 is tangent to the edges of four adjacent circular iron sheets 2, so that each of the four circular iron sheets 2 A four-pointed star-shaped iron sheet 3 is formed between the iron sheets 2;
[0059] Step S11, machining a perforation in the center of the four-pointed star-shaped iron sheet 3;
[0060] Step S12, stamping the circular iron sheet 2 connected with the four-pointed star-shaped iron sheet 3 into a first iron sheet having the cover 10 and the skirt 11;
[0061] S...
Embodiment 3
[0065] Such as Figure 6 as shown, Figure 6 It is a schematicflow chart of Embodiment 3 of the manufacturing method of the bottle cap of the present invention.
[0066] The manufacturing method of the bottle cap proposed in Embodiment 3 of the present invention, on the basis of the first embodiment, also includes after step S11:
[0067] Step S20, cutting two corners of the four-pointed star-shaped iron sheet 3 away from the circular iron sheet 2 into an arc shape.
[0068] By cutting the two corners of the four-pointed star-shaped iron sheet 3 away from the circular iron sheet 2 into an arc shape, on the one hand, it avoids the two sharp corners from scratching the user, and on the other hand, it also makes the appearance of the entire bottle cap more beautiful.

Abstract
The invention discloses a stamping die for manufacturing a bottle cap. The stamping die comprises a first die core and a second die core. The first die core is used for stamping out a first iron sheet with a cover part and a skirt part. The second die core is used for stamping out convex wrinkles and concave tooth-shaped openings of the skirt part. The first die core comprises an upper die core body and a lower die core body, and the lower die core body is provided with a cavity in a reversed shape of the upper side body. The bottom of the upper die core body is a small cylinder, the middle of the upper die core body is a circular truncated cone, and the top of the upper die core body is a big cylinder. The second die core is a steel cylinder, the inner wall of the side face of the cylinder comprises a plurality of first protrusions matched with the concave tooth-shaped openings and a plurality of concave parts matched with the convex wrinkles, an arc-shaped protruding block is arranged at the bottom end of the cylinder, the bottom edge of the arc-shaped protruding block is flush with the bottom edge of the cylinder, the thickness of the arc-shaped protruding block is half of the thickness of the cylinder, and the bottom of the arc-shaped protruding block is matched with the top of a perforated hole.
Description
technical field [0001] The invention belongs to the technical field of container seals, and in particular relates to a bottle cap and a manufacturing method thereof, a stamping die for manufacturing the bottle cap and a bottle. Background technique [0002] In the existing market, most alcoholic beverages, carbonated beverages, and canned food are packed in glass bottles. However, since glass bottles are difficult to inject fine threads like plastic bottles, glass bottles are generally made of iron. Iron or steel materials are used to make bottle caps, because iron or steel materials have good hardness, and they are easy to wrap with the bottle body after being processed into a certain shape. However, since the iron or steel bottle cap has good hardness and is tightly packed with the bottle body, special tools are needed to open it. [0003] Usually, after people buy alcoholic beverages, carbonated beverages or cans, such as beer, they cannot obtain the tools for opening be...
