Problems solved by technology

The carrier of the iconic pattern is mainly the chain tooth body of the metal zipper, and the technology for forming patterns, trademarks, patterns, etc. on the zipper is not yet mature, such as directly pressing the pattern on the chain teeth or using laser engraving The chain teeth will be deformed during pressing or engraving, resulting in poor structural stability, large single tooth displacement, easy loosening, and greatly reduced pulling and closing smoothness
Therefore, none of the current zipper processes can produce a zipper meeting the above requirements.

Embodiment Construction

[0033] In order to further disclose the process of the present invention, a specific description will be given below in conjunction with accompanying drawings 3, 4, 5, 6, 7, 8, 12, and 13.

[0034] The present invention comprises the following steps:

[0035] A. Feeding, the metal wire is sent into the stamping area of ​​the metal shearing extrusion die through the feeding mechanism of the punch-type host machine;

[0036] B. Trimming, both sides of the metal wire are cut off the side waste between the two chain teeth by the cutter on the first station of the metal shearing extrusion die;

[0037] C. Do point, the metal wire is extruded by the do point cutter on the second station of the metal shearing extrusion die, and a protruding point 1 and a groove 2 of a sprocket are formed on the upper and lower sides of the metal wire to form a sprocket tooth;

[0038] D. Cutting, the gear cutting knife on the third station of the metal shearing extrusion mold cuts off the formed sp...

Abstract

The invention relates to the technical field of zipper, in particular to a manufacturing process of carved patterned metal zipper and a molding module. With artful design of first web and innovation of carved patterned process of sprocket body of a sprocket, the invention punches the first web of the sprocket on wire rod when cutting off the sprocket, moreover, the first web is a double bottle-port first web; and then a clamping flowering mode of the module is used for clamping the first web on a cloth belt to form a one-sided zipper. The invention has simple process, moreover, sprocket body of the sprocket of the zipper is pressured with brand mark and picture so that art component of the invention is increased, with anti-counterfeiting function, high synthesis strength, small shifting of single tooth, difficult alteration and high drawing proper degree.

Description

Technical field: [0001] The invention relates to the technical field of zippers, in particular to a manufacturing process of a carved metal zipper and a molding die thereof. Background technique: [0002] Zippers have become one of the indispensable daily necessities in people's lives in today's society. Zippers are classified according to their materials, mainly including: metal zippers, nylon zippers and plastic steel zippers; according to their uses, they mainly include: clothing, bags, shoes and hats, Toys, industrial, medical, etc. According to the requirements of use, it mainly includes: one-way zipper and two-way zipper. Metal zipper is the originator of all zippers. Due to its strong, durable and chemically stable properties, there is currently no other product that can replace it. However, the structure of the metal zipper has always been single. The earliest P type, as shown in Figure 1, includes a bump 1, a corresponding groove 2, and a tooth body 3. This chain ...
