[0002] Metal zipper is the originator of all zippers, it is still widely used and has become one of the indispensable daily necessities in people's life, due to its durable and chemical properties Stable characteristics, so there is no other product that can replace it. In the past fifty years, with the vigorous development of the manufacturing industry, the output of metal zippers has also increased steadily, and the manufacturing methods of metal zippers have also been continuously innovated. , high efficiency, energy saving, and scientific purposes, continuously improve, develop and explore its manufacturing methods, and strive to introduce a method with lower manufacturing costs
[0003] Nowadays, flat metal wires are commonly used to make zipper elements, which have the following disadvantages: 1) Poor performance: the zipper elements are deformed and the finish cannot meet the requirements, so The finished zipper has a low smoothness of pulling and closing; 2) High cost: there are many waste materials and side materials generated, and the material utilization rate is extremely low, resulting in high cost; 3) Low efficiency: the waste material is not discharged smoothly, and the production efficiency is low

Embodiment Construction
[0016] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0017] Such as figure 1 As shown, the metal wire of the present invention includes a head 1, two legs 2 extending from the head 1, a claw 3 located at the front end of the leg 2, and the claw 3 has an inwardly protruding occlusal point 3 After being made into chain teeth, the occlusal points 3 of the two claws cooperate with each other to tightly bite the zipper tape. Preferably, some anti-slip grooves can be processed on the inner surface 21 of the legs, which can not only increase the friction with the zipper tape, but also make the fastener elements difficult to fall off from the zipper tape after being stressed, and can also play a role in m...

The invention discloses a metal wire for manufacturing zipper teeth. The metal wire has a Y-shaped section, and comprises a head, two legs extending from the head and claws positioned at the front ends of the legs, wherein the claws are provided with an inward protruding occlusion point. The metal wire is reasonable in structure, and convenient to process; when the metal wire is used for manufacturing the zipper teeth, waste materials are a few, so that materials are saved, the production efficiency is high, and the metal wire is suitable for batch production; and the produced zipper teeth have high strength, and are well engaged with a zipper belt.
Description
technical field [0001] The invention discloses a special-shaped cross-section metal strip wire, in particular to a special-shaped cross-section metal wire used for making zipper elements. Background technique [0002] Metal zipper is the originator of all zippers. It is still widely used and has become one of the indispensable daily necessities in people's life. Due to its durable and stable chemical properties, there is no other product that can replace it. Nearly five years In the past ten years, with the vigorous development of the manufacturing industry, the output of metal zippers has also increased steadily, and the manufacturing methods of metal zippers have also been continuously introduced. Focusing on the purpose of being simpler, more efficient, energy-saving and scientific, the manufacturing methods have been constantly improved. Improve development and exploration, aiming for a method that is less expensive to manufacture. [0003] Nowadays, flat metal wires a...
